"Supergirl is what I can do, Kara is who I am."

- Kara Danvers

Kara Zor-El (born 1966) is the daughter of the scientist Zor-El and judge Alura. Kara was sent to Earth from the dying planet of Krypton to protect her younger cousin Kal-El. However Kara's pod was knocked off course by Krypton's explosion, sending her ship into the Phantom Zone where she slept for decades while being suspended in time and not aging. Her pod later escaped, and she arrived on Earth where she was placed with the Danvers family by an adult Kal-El, now "Clark Kent", later becoming Kara Danvers. She was the personal assistant of Cat Grant at CatCo Worldwide Media until she was promoted to reporter, and is the superheroine known as Supergirl, stylized as the "Girl of Steel", the "Maiden of Might" and the "Last Daughter of Krypton".

Early life
Kara was born in 1966 on the planet Krypton, in the prestigious House of El, to her parents; scientist Zor-El and judicator (judge) Alura Zor-El. In her house she had a room that overlooked the city. As a child Kara went often on vacation with her parents in different planets such as Starhaven and Sedenach.

One night Kara stayed up late to see her mother. Questioning her mother as to why she had come home so late, Kara was told by Alura that a Hellgrammite had been brought before the citadel. When Kara mentioned that she wanted to help people like Alura did one day, she was told by her mother that she would, as she had the heart of a hero. After being told to get some rest by her mother, Kara researched Hellgrammites.

Kara was given a spy beacon by her aunt, Astra, which could be used to call her. When Astra disappeared, Kara messaged her and Astra arrived, telling her that Krypton is dying. Unbeknownst to Kara, it was part of Alura's plan to lure Astra out of hiding to arrest her for her crimes.

Phantom Zone
At the age of thirteen years old, Kara was sent to Earth from the dying planet of Krypton, charged with protecting her baby cousin Kal-El. Until a her pod went off course and left her in the wrong solar system. Her mother told her that due to Earth's yellow sun, she'd have extraordinary powers and go on to do amazing things, but also told her to watch out for what she does and make sure it was for good.However, when Krypton exploded, Kara's ship moved towards the Phantom Zone. She slept there for 24 years until she awoke and noticed computer console in her dashboard that lights up with a logo with three dots in a triangular shape, before Fort Rozz's engines activated.

Sent to Earth
Kara's pod finally landed on Earth. Since time doesn't pass in the Phantom Zone, she still appeared as a thirteen-year-old girl. She was found by a then adult Kal-El, or Clark Kent who had gone on to fame as Superman. She was then taken by Kal-El to live with Jeremiah and Eliza Danvers, a pair of scientists who once helped him understand his own abilities. When she landed, she had frequent panic attacks and was horribly claustrophobic. The claustrophobia was caused by her being stuck in her pod for so many years. She was enrolled at Midvale Junior High School along with Jeremiah and Eliza's daughter Alex Danvers. Kara was freaked out by her new world along with her developing powers. When they went to the beach she embarrassed Alex by staring at the birds as they did not have them on Krypton. When a car crashed close by Kara ran at super-speed to the rescue saving a mother and her child with her super-strength. However Alex was injured by a car door when it exploded. After that, Jeremiah and Kara decided that it was best for Kara to hide her powers, and Jeremiah gave her a pair of glasses she could wear to suppress her vision. One night, on the roof of the Danvers' house Kara convinced Alex to sneak out and go flying with her, despite the latter's initial protests. Kara and Alex were later caught sneaking in by Eliza and Jeremiah, and lectured about the rules. After someone knocked on the door, the girls were sent up to their room, with Eliza telling Kara not to use her super hearing to listen in on their conversation. One year later, her adoptive father 'died' protecting a martian, from D.E.O.'s ruthless director Hank Henshaw, but her adoptive mother told she and Alex that he died in a plane crash.

Kara was invited by Superman to see the Fortress of Solitude several times, though she rejected the offers as she thought it would remind her of Krypton. Over the years the bond between Kara and Alex became so strong that none of them can imagine her lives without the other.

Deciding that the world didn't need another hero, for the next twelve years Kara decided to live a normal life. In high school Kara was friends with Kenny Li until his death. She was also bullied by a girl she nicknamed Belinda-The-Bully and, when she attended the prom, she accidentally stomped on the foot of her partner, breaking him three fingers. After graduation Kara went prior to Stanhope College and then to National City University, where she earned a Bachelor of Arts degree in Marketing; Kara did a summer internship at the Midvale Newspaper and spent three years waitressing at Noonan's Restaurant before she went in for an interview at CatCo, meeting Winn Schott, and using her abilities during the interview to secure the job.

Her sentimental life was always difficult and she often had trouble with kissing having broke the noses of at least four guys due to not controlling her strength, in which she confessed to her lover, Mon-El later.

Embracing her powers
After a failed date, Kara saw on the news that Flight 237, the one her sister Alex Danvers was flying on to go to her conference in Geneva, was going down. Attempting to save the flight, Kara used her abilities for the first time in years, successfully helping the plane land, though not without causing damage to Otto Binder Bridge. Though was later berated at her apartment by Alex, who was upset that she had revealed herself to the world, and couldn't take it back. Deciding to become a hero, Kara confided her secret in Winn the next the day, on the roof of CatCo. With Winn's help, a costume was made, and Kara was able to stop a bank robbery and car chase. Kara was later subdued by the Department of Extra-Normal Operations while trying to stop a fire, the latter whom used Kryptonite darts. Meeting Director Hank Henshaw at the DEO base, it was explained to her that when her ship got loose from the Phantom Zone it dragged Fort Rozz, Krypton's maximum security prison with it to Earth. Though she offered to help, her offer was rejected by Henshaw. The next day, Kara was furious Cat Grant had dubbed her Supergirl, later being contacted by a Fort Rozz escapee, Vartox, and although she was defeated on their first encounter, she later convinced Henshaw to give her another try, in which she defeated him. It was later revealed to Kara that Superman had asked James to come to National City, as Superman had asked him to come there to keep an eye on her. Kara was confused as to why he didn't just tell her he wanted her to be a hero himself, with James revealing to her that Superman wanted her to choose it for herself, the same way he had to, as that was what made a hero. Kara was then given the blanket Kal-El was wrapped in as a baby, that James had been entrusted to give to Kara for her to use as a cape. A week later, Kara tested her abilities with the D.E.O.. She later stopped a fire at the National City Port, and the next day at work, Kara was present at the meeting where Cat told her employees that she wanted an interview with Supergirl. However, Kara soon after told James that she wasn't going to do it, as Cat would recognize her. Kara was later contacted by Alex regarding an alien theft at Plastino Chemicals, with Kara identifying it as a Hellgrammite afterwards. Kara offered to subdue the Hellgrammite, though her offer was rejected by Henshaw who wanted her to prove that she could handle herself beforehand. Kara was then brought into the D.E.O. training room and swiftly defeated by Alex. Arriving into work the next day sore, Kara took advice given by Cat Grant of starting small and working her way up, and enlisted the help of both Winn and James. With their help, Kara was able to handle several situations. Later at her apartment, she thanked Winn and James for their help, and was soon after given an apology by Alex. The following day, Kara listened in on James' conversation with Cat, giving him a pep-talk after he was given a dilemma by Cat. Directly after, Kara was called by Henshaw who notified her that Alex had been abducted by the Hellgrammite. After criticizing Henshaw, Kara tracked down Alex at the warehouse she was being held captive at. There, she discovered her aunt Astra was still alive, and a fight between the two ensued. Kara and Alex were saved from Astra by Henshaw, and later at the D.E.O. Kara was shown a room that had been setup for her to communicate with her own personal A.I.. Kara later carried Cat's car to a remote location for their interview, telling Grant that James Olsen had told her that Cat had wanted to talk to her.

During her interview with Cat, Kara accidentally revealed that her and Superman were cousins, flying off afterwards. The next morning at Noonan's, Kara was teased about her crush on James by Alex, who also told her she had to stop telling people her identity as Supergirl. At CatCo, Cat told Kara that she would be writing an expose on Supergirl for a issue of their monthly magazine, and that'd they be having a big party to launch it. Kara was later alerted by Agent Vasquez of a multiple car collision on the highway. While there she encountered a masked villain who attacked her, after brief battle between the two, the man flew away after she damaged his suit. Back at the D.E.O. headquarters, the man was identified as Reactron, an old villain of Superman. Afterwards Kara was told by Henshaw that the D.E.O. wasn't going to help her deal with him, as Reactron was human, and fell out of their jurisdiction. Later, Kara and James were shown Ed Flaherty's old office by Winn, who had turned it into a base for their Supergirl matters. While going over Reactron's powers and his history with Superman, James suggested that Kara call Superman for assistance, much to her reluctance. After being informed of Maxwell Lord's capture by Reactron, and discovering the latter's identity, Kara found out the location of Reactron's hideout, saving Maxwell though she was soon defeated by Reactron, and subsequently saved by Superman. The next day she discovered that Supergirl was being discredited by Lord in the media because of Superman's intervention, and dismissed James after discovering that James called him. At Cat's party, Kara danced with Winn and later James, though Reactron broke in interrupting them. As Supergirl, Kara stops him, successfully removing the power core, powering his suit. Back at her apartment, Kara and Alex make up, with Alex suggesting that Kara asks James out. However when Kara goes to his office the next day, Kara sees Lucy Lane, James' ex, who arrived to talk to him. Kara overhears the conversation, leading her to believe that Lucy wants to get back with James. Upset about this, even giving Winn the cold shoulder, Kara received a texted apology from Clark. While flying in National City, Kara encountered a drone and destroyed it, afterwards blaming the D.E.O. for following her. Later at CatCo, Kara offered to watch Cat Grant's son after discovering that Grant had won the Siegel Award for Women in Media, and didn't have anyone to watch him. At Noonan's Kara talked with James about his relationship problems with Lucy Lane, leaving after finding out a bomb had went off in a building nearby. After saving the building, Kara was soon after reminded by a call from Cat Grant, that she was late to pick up Carter. After picking up Carter at St. Edmund Hall, Kara brought him back to CatCo, and later stopped James from venting to her about Lucy. Kara then received a call from Alex about the bomb at Lord Technologies, arriving there as Supergirl, and successfully getting the bomb clear of the city, being knocked unconscious from the bomb's explosion. She later awoke at the D.E.O., and was informed of the bomber's identity, Ethan Knox. Though she offered to help, Kara was ordered by Alex to sit out on the case, after falling from the height she had. While getting lunch from Noonan's, Kara encountered Lucy Lane who confided in her about her problems with James, which she later recounted to James. While going to protect Maxwell Lord's super train on it's opening, Kara was alerted to a bomb at Lord Air Terminal. Kara then received a call from Winn who told her both Carter and Knox were on the train, deducing that there two bombs, and telling Alex and Hank to handle the airport, and she'd handle the train. Arriving on the train, Supergirl alerted Lord of the bomb, and told him and Carter to get all of the passengers to the back of the train. After finding Knox, she pleaded with him to deactivate the bomb, though to no avail, having to detach the train car that Ethan was in from the rest of the train, watching it blow up from a distance. The next morning she was berated by Cat for letting Carter get onto the train, and later that day confronted Maxwell Lord after discovering he was the true culprit behind the bombings.

As Supergirl, Kara stopped an alien convict from escaping the D.E.O.. At her apartment, Kara along with Alex greeted Alex's mother, Eliza Danvers, with the Eliza complimenting Kara on her work as Supergirl. At CatCo Kara invited Winn to her family's Thanksgiving dinner, after finding out he had no plans. Afterwards she listened in on Cat demoting Leslie Willis to the traffic chopper, and she later in the day had to save Leslie from the helicopter after lightning hit the aircraft. While doing so, lightning deflected off of Kara it deflected onto Leslie, putting her into the hospital. The next day, Kara went with Cat to visit Leslie in National City Hospital. During Thanksgiving dinner, Kara announced that before everyone ate, she wanted them to go around saying what they were all grateful for. After going first, Kara excused herself to answer a call from James. After an argument between Eliza and Alex broke out, and Winn and Alex left, Kara left to handle an emergency for Cat Grant. While there, Livewire arrived and attacked both Kara and Cat, with Kara causing Leslie to flee as Supergirl. Later, Kara discussed what had happened with Henshaw, who deduced that Kara was the Element X in Leslie getting her powers. Back in Cat's office, the two had a conversation about the death of Kara's parents, her current family problems, and Cat's problems with her own mother. Kara agreed to ask the FBI for a direct line to Supergirl, as well as taking Cat's offer to go home. At the D.E.O. Kara was given a industrial capacitor to capture Leslie with, and working with Cat, she was able to grab a water pipe under the street and short out Leslie with it. Before leaving, Eliza revealed to Kara and Alex that Jeremiah died working for the D.E.O., under Hank Henshaw.

Kara later broke up a road rage between two men, causing one of the men to confront her. Kara caught his punch, and twisted his arm, scaring children in the process. She was later criticized for her actions by both Maxwell Lord, and Hank Henshaw. Kara and Alex later persuaded Winn to hack into the D.E.O. mainframe to discover what had happened to Jeremiah Danvers. Both Kara and Alex were called by Henshaw, and at the D.E.O. base camp, General Lane arrived, demanding that Supergirl fight their field robot, Red Tornado. The next day, Kara as Supergirl flew to the D.E.O. base camp for her fight with Red Tornado. As the fight progressed, Supergirl lost her temper, breaking off Red Tornado's arm in the process. At CatCo, Kara lashed out at Cat, as she was frustrated with always being yelled at, despite working hard at her job. Kara and Cat later had drinks together at Noonan's, with Cat giving Kara advice on controlling her temper at work, furthermore find out why she was angry. Kara was alerted by James of Red Torando's appearance, with Kara arriving as Supergirl and engaging the android in combat. However, Kara had to diffuse a tornado Red Tornado caused, allowing it to escape. At a garage Kara and James blew off steam together, with Kara hitting a car, losing her temper, and soon after confiding in James that she thought she'd never find love or a normal life. At the D.E.O., Kara was informed by Alex that Morrow was still controlling Red Tornado. After the D.E.O. drew the robot out using hologram technology, Supergirl engaged Red Tornado and used her heat vision in an attempt to stop Red Tornado once and for all, causing the android to explode. While later cleaning up a glass from a cup she had dropped, Kara cut herself, much to her surprise.

She was later informed by the A.I. hologram of her mother, that her powers had been drained after she used the full power of her heat vision. Though she is told that her abilities should return in a few days, and Kara is urged by Alex to enjoy her day without her powers. Kara is later sent home by Cat for the day, when Cat sees her sneeze. She later encounters James, and a earthquake occurs soon afterwards, with a car almost colliding with Kara, and although James knocks her out of the way, she sustains a broken arm. After Maxwell Lord criticized Supergirl's absence, Kara and James visit him, with him claiming that Supergirl no longer has her powers due to her recent fight with Red Tornado and may never get them back. Back on the streets, Kara is present when Maxwell attempts to save a woman's father, though in the absence of an X-ray machine to find a venous thrombosis, he fails. Without her power of X-ray vision, Kara is unable to save the man as well, making her feel helpless. Kara hears a robbery happening nearby, showing up as Supergirl, and talking the robber out of it, with James snapping a photo of the event. She is later informed by Winn, that an adrenaline rush will restore her powers. After James almost falls down an elevator shaft, the moment allows for Kara's powers to return. With her powers back, Kara stops several disasters, including a bus of children from falling off a bridge, and a fire at West National City Bank. Kara was later told by Winn that he was disappointed in her, for her actions with James, despite him having a girlfriend. She later thanked Cat Grant as Supergirl for her actions during her absence, and while flying, Kara was attacked by three Kryptonians, led by her Aunt Astra.

Kara fights them off, and although Astra attempts to persuade Kara to join them, Kara refuses and leaves. She then returns to the D.E.O. to inform Alex and Hank, though they suggest she not rush anything, and get some rest. The following day, Kara is asked by Cat to bring in Winn and James for help after news broke of her leaked email server. At the D.E.O., Kara sparred with Alex, with the latter chiding her for hesitating during their session, and furthermore that she thought DEO should handle the Kryptonian threat, because of Kara's familial ties. Kara and James informed Cat that there wasn't anything in the emails that could be used to slander her, though Kara was later told by Cat to keep looking for any more leaks, as she suspected Dirk Armstrong was going to find some way to damage her reputation. Kara, using her hearing, listened to Armstrong admitting to having set Cat up. Kara then asked James to enlist Lucy's help in tracking a paper trail to clear Cat's name. Soon after Kara went to confront Astra, who had called her out publicly. During their battle, Kara eventually gains the upperhand, taking an unconscious Astra back to the D.E.O.. There, Kara discovers her mother used her to summon Astra in the past, to get the latter arrested. At CatCo, Kara learns about Adam Foster, an individual in Opal City Cat had been paying money to. She later finds out from Cat that Adam is her estranged son. Kara is later present when James, Winn, and Lucy arrived presenting her with evidence that Dirk was behind the leaks. Later, Kara goes to Cat, and is surprised to learn that Cat found out that she was Supergirl. During which, Kara gets a call from Alex, and excuses herself and arrives ready to battle Non.

During her fight with Non, Hank is abducted by Non. At D.E.O. headquarters, Kara asks Astra where Non took Hank, but she refuses to reveal anything. Kara tells James and Winn of Cat suspecting her to be Supergirl, a suspicion Cat continues to test through various challenges. Kara is present when Non contacts the D.E.O., offering to trade Hank for Astra. Much to her horror, Kara later has to sit by while General Lane tortures Astra with a Kryptonite injection. Kara later has to save Alex and another D.E.O. agent from an explosion after Astra's revelation of Hank's location turns out to be a trap. At CatCo, Kara is given the dilemma of proving that she isn't Supergirl, or Cat will fire her. Later, Kara thanks Cat for the opportunity to work with her and resigns, explaining that Cat's suspicions make it impossible for her to do her job. Afterwards, she discovers James' injuries that he had sustained, after investigating Maxwell Lord, announcing that she'd go after him. While visiting Astra, Astra tells her that going through with the exchange is the only way to rescue Hank. Kara agrees, though there is initial protest from General Lane. She is present when the trade is made, and though Non springs an ambush, Astra calls off the attack, demanding that Non honor the agreement. Hank later uses his shapeshifting ability to impersonate Supergirl so that Cat can see her and Kara at the same time, and Kara is offered her job back. Though Kara is offered full-time job at the D.E.O. by Hank, she rejects it because her relationships at CatCo are what humanizes her. She later has an online chat with Superman, who offers her both support, and assistance if she ever needs it.

During a flight together, Kara attempts to convince a reluctant J'onn to embrace his powers and reveal himself to the world. The two are then joined by Alex and the three come up with a plan to find out what Maxwell is hiding at Lord Technologies. Kara is later present when Agent Cameron Chase arrives to question him about his father's whereabouts. Kara then confronts Winn, who tells her his father's crimes, and Winn then shows Kara a doll he received on his desk, from Winslow Sr.. Later, Kara questions Cat's reason for hiring Lucy, only to have Cat accuse her of making a move for James. Kara goes along with Winn, when the F.BI. has him go to an arcade to meet his father, in a trap. She later saves several agents and Winn from poisonous gas, inhaling the gas and dispersing it into the air. Back at CatCo, Kara is informed that Winslow Sr. must be hiding in an abandoned factory that he use to own and Kara flies off to capture him before the FBI does. When she arrives at the factory Kara is trapped in a box of quicksand, and overhears a girl's voice from an overhead box that is about to be dropped into a shredder. She escapes but discovers a Supergirl doll in the box, allowing Winslow Sr. to escape. At her apartment, Kara is kissed by Winn while the two were talking, though she rejects him. At National City Toy Con, Kara later saves Winn from being shot by several F.B.I. agents, and uses her x-ray vision to see Winslow Sr. set bombs on a timer. She turns on the sprinklers and freezes the water to create a frozen shield that protects the Con's attendees, foiling Winslow Sr.'s plans and subduing him. Later at CatCo, Kara tries to apologize to Winn, who in turn apologized for kissing her, though isn't sure where they stood because of his feelings for her. Later that evening Kara flies in with her Supergirl costume into her apartment, confiding to Alex about Winn's feelings for her and admitting she felt guilty about it.

Kara is later on the verge of being fired because Adam Foster arrives in National City, after receiving a letter written from Kara, who pretended she was Cat. However, Kara turns things around by offering to have the two dine together by getting them reservations. She later saves Senator Miranda Crane when a White Martian attacks the rally, and afterwards offers to J'onn to help take it down. Kara helps Cat out with getting to know Adam before their dinner, and is later shown photos by James of the White Martian's attack at the rally, who notices that some of them show Miranda's eyes glowing white—much like those of the White Martian. Kara calls Alex, telling her that the White Martian is at the D.E.O., disguised as Miranda. Kara shows up as the White Martian is about to attack, only for the White Martian to escape. At CatCo, Kara tends to Cat who is upset over the dinner earlier because of the letter, which prompts Kara to go see Adam personally. After a short talk and an admission from Kara about the letter, Adam agrees to meet with his mother on the condition that Kara joins them. During their dinner, Kara acts as a mediator and successfully helps mend their relationship. Later, Kara goes with J'onn to the desert to rescue Alex, and defeat the White Martian. During the battle, J'onn puts Kryptonite handcuffs on Kara so he can kill the White Martian, though Kara talks him out of it. At the D.E.O., Kara is thanked by the real Miranda Crane, and later Kara is asked out on a date by Adam, which she agrees to. At her apartment, Kara and Alex see a Supergirl impostor save a car from falling.

At the D.E.O., Kara suggests the impostor is a clone. Kara later notices Cat being nice to her because she was dating Adam. During her date with Adam, Kara sees a news report of a stranded tram, prompting her to bail. Atop the tram, she was confronted by Bizarro, who ignores her questions and attacks her. During their fight, they broke the tram's support, causing it to fall. Supergirl catches it while Bizarro watches in slight puzzlement. Kara is later asked out on another date by Adam, which she was convinced to go on by Alex. On their date, Adam and Kara discussed their parentage, and Kara said it's hard for her to feel normal, though Adam told her no one feels normal and the two kiss. During which, Bizarro swooped down and dragged Kara away. The two fought and Bizarro gained the upper hand until Alex arrived, firing at Bizarro with Kryptonite weapons, causing her biological structure to mutate and decay. Bizarro screamed her hatred for Supergirl before flying off. Kara realized that Bizarro came after her in her civilian identity and deduced that Max knew her secret identity. Kara stated they need to stop Max once and for all. Back at CatCo, Kara broke up with Adam, citing she didn't have room in her life for him. She was later alerted to James' position after he had been captured by Bizarro. Supergirl and Bizarro fought again and the latter tried to strangle Supergirl, though Alex got a clear shot and knocked Bizarro unconscious. Supergirl later got an apology from Bizarro before she was put under. Kara later went to confront Maxwell, telling him he'd never hurt anyone again, before the latter threatened her foster mother, angering Kara. At CatCo, Cat told Kara she wanted their relationship to go back to being strictly professional. Kara was later attacked by a creature when she arrived back at her apartment.

Black Mercy and the death of Astra
Kara woke up on a bed and was surprised to find herself on Krypton, with her mother Alura claiming that Kara had been suffering from "Argo fever". She later panicked as she did not have her powers or didn't understand what was happening. She was distracted by a carving she made for Zor-El when she was eight, but was conflicted over her memory of leaving Krypton as well. She was determined to get to the bottom of the mystery and go home. Kara's memories of Earth later faltered, and she was finally distracted and placated by a young Kal-El, who asked her to open an intricate orb, which she did. The orb opened a large holographic display of the cosmos. With Kal-El pointing out Krypton and Kara quietly agreeing with him that it was beautiful. When Alex arrived in the hallucination, Kara knocked her out with a sculpture, having no memory of her life on Earth. Kara's memories were later jogged when Alex was being sentenced, and she was freed from the Black Mercy. After she awoke, Kara angrily demanded to know who had done it to her, and angrily confronted Non, pummeling him. She later spoke to Astra during her last moments, while she was dying. She later arrived back at her apartment, to find Alex, Winn, and James waiting for her. Later at her apartment, Kara was summoned by Non to attend Astra's funeral. She was also told that there'd be a two week mourning period, and then Non would kill her. At the D.E.O., Kara refused to release Maxwell Lord, and the next day at CatCo, Kara was informed by Cat that she had hired a second assistant. After being one-upped by Cat's new assistant, Siobhan Smythe, Kara overheard Cat telling James and Lucy to investigate Maxwell Lord's disappearance. Soon after, Kara argued with James over the D.E.O.'s ethics, and holding Max without due process. She was later questioned by Siobhan about the nature of her and James' relationship via message, though Kara told her they were simply friends. She later confronted Master Jailer, eventually becoming entangled in chains, allowing him, along with the Fort Rozz escapee he was hunting, to escape. Back at the D.E.O., Hank identified the alien as Luzano, a former drug smuggler Alura had put away in the past. She was later once more confronted by James about the D.E.O.'s imprisonment of Maxwell Lord, though she told him that she did what needed to be done. Kara later discovered that Master Jailer was a police detective through Alex, and confronted him in his civilian guise. She was soon after captured by Master Jailer, finding herself in a cage without her powers. While there she talked with Professor Luzano, with him telling her, his story. The two however were saved by Alex and the D.E.O., and Kara was able to defeat Master Jailer. Kara and Alex later released Maxwell Lord, and later after unsuccessfully questioning her A.I. about Myriad, told Hank she didn't know how to work with him after what he had done to Astra.

In the days following, Kara rejected Alex's offers of coming back to the D.E.O.. She later prevents an accident, after a hacker who appears on CatCo monitors, disrupts the city's traffic signals. Back at her apartment, the hacker teleports through a computer when Winn attempts to crack the hacker's code. However, Alex and Hank arrive, and after making the hacker retreat, she rejects another offer to come back to the D.E.O.. Kara is later taken to Superman's Fortress of Solitude by James, where she questions Kelex, telling it that she's looking for a Coluan. Kelex tells her the hacker is Indigo, a descendant of Brainiac and a prisoner at Fort Rozz for attempted genocide, and is considered the deadliest of all the escaped prisoners. She later tries to talk to Lucy after she gets mad at James for missing their date, recounting a story James told her about how he got his camera. Kara later arrives at a military site to fight Indigo, who was attempting to launch nuclear missions at National City. However, she is forced to abandon the fight when Indigo activates a missile. She attempts to push it off course, but it simply adjusts its path and continues to fly towards National City. With Hank's help however, she is able to successfully disarm the missile. Indigo attempts to launch more missiles though Kara returns to stop her. She is later defeated for good, after being infected by a virus that disabled her. Kara later tells James that he can tell Lucy her secret, though he reveals Lucy broke up with him. Kara later returns to work at the D.E.O., with Alex coming clean about killing Astra, causing the two to embrace. Kara is later infected with Red Kryptonite when she flies out to help a fireman trapped by debris in a fire. The next day, Kara smashes her alarm clock and arrives for work at CatCo wearing somewhat more stylish attire than normal. She later let a K'hund Fort Rozz escapee go after defeating him, and afterwards criticizes Hank for hiding his abilities when him and Alex confront her. At CatCo, Kara gets Siobhan fired by luring her away from her desk long enough to print a copy of the email of her trying to sell the story of Supergirl letting the alien escape, to the Daily Planet. Kara invites Winn and James to celebrate at a club. Kara arrived late, and persuaded James to dance with her. She tried to come on to James, and trashed Lucy in the process. Kara later flies to CatCo, and tells Cat that she's no longer interested in being a hero. To prove her point, she throws Cat over the balcony, and flies down to catch her just in time. Later at her apartment, Kara adopts a new uniform, similar to what Astra and the rest of the Kryptonians wore, laying into Alex when she arrived, pouring out years of resentment. Flying off, Kara wreaked havoc on National City, causing Hank to reveal his true martian form, as J'onn J'onzz and engage her, allowing Alex to use an antidote on her. Kara is later horrified at her actions under the influence of Red Kryptonite, and attempts to soon after apologize to both James and Cat, though unsuccessfully.

Days after, Kara went to stop a bank intervention in the morning, though everyone fled when she arrived, due to her scaring everyone while under the influence of Red Kryptonite. She then took a sick day at work, and later fails at listening in on Colonel James Harper's interrogation of J'onn. Kara along with Alex later object when J'onn is taken into custody, though to no avail. She is later shocked, when Alex is also taken into custody, and the two are both being sent to Project Cadmus. Kara later has James explain what Project Cadmus is, and Kara is forced to reveal her identity to Lucy in an attempt to save J'onn and Alex. Both Kara and Lucy later break J'onn and Alex out while they were in route to Project Cadmus. Kara offers to hide Alex in the Fortress of Solitude while she finds Jeremiah, but Alex insists that she has to be the one to find him. Back at the D.E.O., she agrees to help Lucy, as Lucy is promoted to acting director of the D.E.O.. Upon being informed that a bank robbery is underway, Kara heads off to stop it. However, she didn't know if National City would ever trust her again, though Lucy reassures her that if she can win her trust, she can win back the city.

Livewire and Silver Banshee
Kara along with Winn later took Siobhan to the D.E.O. after she had fell from a roof, as she'd displayed the power to save herself. Later at CatCo, Kara was sent flying by Siobhan using her sonic scream. However, she was caught by The Flash, who accidentally ran them to the desert. Kara proceeded to fly off, but stopped in order to talk to him. Introducing himself and explaining that he was from another universe, he asked for her help to return. Kara took Barry to their makeshift base at CatCo, where he was introduced to Winn and James, explaining to all of them the concept of the multiverse. Promising to help him get home, Kara enlisted Barry's help with Siobhan and Livewire. She then took him to the D.E.O., introducing him to director Lucy Lane. Tracking Siobhan and Livewire, they found them at an abandoned warehouse. Despite being unsuccessful in their attempts to subdue them, Barry suggested that Kara needed to slow down and stop trying so hard, drawing from personal experience. Back at the D.E.O., Kara was contacted by James, telling her than Cat Grant had been kidnapped by Livewire and Siobhan, now known as Silver Banshee. Utilizing ear bud-type devices, the two villains were quickly defeated, along with the help of National City citizens and the fire department. Later, Barry and Kara returned to the desert. They combined their speed in a race, with Kara throwing him through a portal that was created. Later at her apartment, Kara and James shared a kiss, though afterwards she was surprised to see him walk away with a blank stare, and joined hundreds of other people marching blankly down the street, all under the control of Myriad.

Myriad
Kara arrives at the D.E.O., and attempts to stop a prisoner, Maxima, from escaping. However, Lucy stops her with Kryptonite bullets, though she is able to stop the rest of the prisoners from escaping by destroying the computer terminal, using the afterburners from her pod. After removing the bullet, she flies to the Fortress of Solitude to find her cousin Superman, but Kelex tells Kara that he is not on Earth and refuses to inform her about Myriad. However, the A.I. of Alura explains that Myriad was a mind-control system Astra and Non were arrested for trying to use against the people of Krypton, also learning Kara that once Myriad is in effect it can't be stopped. Back in National City, Kara is noticing everyone, even Winn and James, are now under the Myriad effect and watching Kryptonian codes on the screen, General Lane has placed the entire city under quarantine, but Kara informs him that she will help save his daughter. However, she soon finds out Maxwell Lord and Cat Grant are both unaffected, due to Max's technology. Non soon arrives, and forces James, Winn, and Kelly to jump to their deaths. Kara however is only able to save Winn and James. Soon after, she warns Alex not to come to National City, or else she'd be under the control of Myriad. She later agrees to go along with Maxwell Lord's plan, though Cat opposes to it. The two go to Lord Technologies to convince Lord not to launch his bomb, and the trio went to Cat's original broadcasting station intending to broadcast a counter signal to Myriad. However, Alex arrives under the control of Myriad, and in Kryptonite armor, engaging Kara in battle. During the fight, Kara was swiftly defeated by Alex, and almost killed, until J'onn arrived with Eliza, who talked Alex out of it, breaking Myriad's control over her. In the broadcasting station, Kara successfully broke Myriad's control over the people of National City, by giving a speech about hope. Later at the D.E.O., Maxwell Lord informed them that the Kryptonians were now using Myriad, increasing the frequency until every human's cranium exploded. Before she could leave, Maxwell Lord warned Kara that this was in fact a suicide mission as she had no backup. After hearing such, Kara gave Winn, Cat, and James goodbyes of sorts at CatCo. She later, identified the device Maxwell Lord had discovered that was powering Myriad, as a Omegahedron, energy devices used on Krypton. After being informed that the Non and the Kryptonians were hiding out in Nevada in Fort Rozz, Kara went to confront them, along with J'onn who the D.E.O. agreed to release. Before she left, Kara gave Alex the necklace her mother had given her, to keep it safe. There, Supergirl and Non fought each other, and Indigo and J'onn battled one another. Kara eventually defeated Non in a heat vision face off, and a dying Indigo revealed that she had locked Fort Rozz's system, so they couldn't fly away the ship, which was powering Myriad. Kara decided to fly the ship into space, telling her sister goodbye over her intercom. While doing so, Supergirl went unconscious. However she was saved by Alex who used her pod to rescue her. Back at the D.E.O., Kara was congratulated, and the next day at work Kara received praise from Clark via message, and was promoted by Cat. Later at her apartment, Kara had a celebratory dinner, though it was interrupted when a pod flying in the sky caught their attention, causing Kara and J'onn. At the crash site, Kara recognized the pod as identical to hers, and was surprised at what she found inside.

Superman's arrival
Kara and J'onn found a comatose alien in the pod and placed him in D.E.O. National City headquarters. Arriving at CatCo, Kara meets miss Grant, who asks her if she decided what position she wants, to which Kara said that has not yet decided. Then Cat gives her 48 hours to make a decision. After that Kara comes home and starts to pick up a dress for her date with James. As he arrives, bringing pizza and ravioli, Kara turns on the TV, where they sees the launch of the Venture spacecraft, which suddenly begins to fall due to engine failure. Kara flew to the accident site, where she was joined by Superman, and together they prevent catastrophe, to cushion the fall of the shuttle. Kara arrives in D.E.O., bringing Superman with her to shows him the man they had found into the pod the previous night. Then Clark decides to join the investigations on the fall of the shuttle, and offers to go to CatCo with Kara. There Kara apologizes to James for having interrupted their date and appoint a new one. After this Kara and Clark go to the Luthor Corp, to talk with Lena Luthor, who explains that she refused at the last moment to flight on the Venture due to an emergency meetings on the renaming of the company and is not related to the accident. Later Lena Luthor's helicopter was attacked by drones, but Supergirl and Superman saved her, destroying them, and then Supergirl told Lena that someone wants to kill her. Later, Kara tried to talk Lena out of doing her speech, but she said that she should do it. During her speech John Corben attacks Lena but she was saved by Supergirl while Superman support a building from collapsing on a square full of people. The next day Kara came to Cat and said that she decided to become a reporter. Cat said she knew that she would have chooses this position. Then, Kara decided to talk with James and told him that in her opinion it is better to be just friends. In D.E.O. Clark told Kara that he decided to stay in National City a little longer.

After she was promoted to reporter, miss Grant introduced Kara to her new boss, Snapper Carr. Kara started to tell him that she would try to be a good reporter, but he just walked away without listen to her. Later, at her apartment, Clark told her that it was time for him to return to Metropolis, to which Kara was clearly upset. At this point, the news reported about a man who is about to jump down a bridge, so Supergirl and Superman arrive at the site only to discover this person is John Corben, who is now a Kryptonite-powered cyborg dubbed Metallo. He struck Kara with a Kryptonite beam and she lost consciousness, but before he can kill her, Superman threw him off the bridge and brought Kara to the D.E.O.; the next day, Kara returned to CatCo and came to Snapper, but he refused to give her any instructions, saying she is not working there, which outraged Kara, who went to miss Grant and ask her for help, however Cat told her that she should resolve her problem by herself and also that she decided to leave the company to experience something new. Later, Winn made Anti-Kryptonite Devices for Kara and Clark. While Superman and the Martian Manhunter dealt with Gilcrist in Metropolis, Supergirl and Alex overcome Corben in National City, as Alex stabbed him in the chest with a piece of pipe while Kara held him. In the evening Kara flew to Cat Grant in the guise of Supergirl and said that she knew that she was leaving, telling her she admires her. Kara then once again came to Snapper, giving him an article about the battle between Supergirl and Metallo with the testimony of eyewitnesses, and the comments of police, but he did not even want to read it entirely, then Kara said she would find another magazine who will take her article, but he stopped her and said to come back tomorrow. Immediately after that, Kara went to D.E.O., to say goodbye to Clark, who returns to Metropolis. Then she decided to visit the comatose alien, who suddenly woke up and seized Kara by the neck, then threw her aside and ran away from the D.E.O.

Dealing with Mon-El
Later J'onn told Kara that President Olivia Marsdin will come to D.E.O. during her visit to National City, which she commits to sign a decree on granting aliens the rights of US citizens, a news Kara was very excited about, especially After Alex tells her that the President expects Supergirl would meet her as her plane arrives. Later, at work, during a meeting Snapper gave each member of the staff a commission instead of James, and Kara, instead of an interview with the President, was sent to Lena Luthor. Kara, in the guise of Supergirl, arrives at the airport to meet Olivia Marsdin, but as soon as she got off the plane, she was attacked and nearly killed if not for the intervention of Supergirl. After that Kara comes to Lena Luthor, as she needed a comment from "the sister of the most famous alien hater". Lena tells her that L-Corp developed a new device that will identify aliens and offers Kara to test it. When Lena turned, Kara used her laser vision to sabotage the device and then agrees to test it, so it gives a negative result. Lena believes that people have the right to know who is an alien and who is not, therefore, she plans to put the device in all the country stores.

In the evening, Kara brings Snapper the article with Lena Luthor's comments, but he refuses to accept it as it is written too biased, and requires a rewrite. In D.E.O. she is struggling with her rewrite before Winn is able to locate the fugitive alien with Alex's help. They find that he's at the observatory and sending out a deep space signal. At first, Kara believes that he's trying to contact Krypton but Winn sees that the signal isn't heading for Krypton but to the planet Daxam. She immediately then goes to catch him. When she arrives, she physically confronts him as she believes that he is the one who attacked the President. A fight breaks out between them, resulting in the Daxamite getting knocked unconscious by Kara. She takes him to the D.E.O., where she explains to Alex, Winn and J'onn that Krypton had warred against Daxam for generations. She went to confront the Daxamite and they fell into a small argument about how each of their planets view the other's people. Kara then asked why he was at the observatory and he told her that he was just sending a distress call as he was stranded. Kara asked him why he had attacked the President if he was marooned but he claimed to not know what she was talking about which she didn't believe.

Later Kara came back to Lena, who praised her for her wonderful article, although she admitted that initially thought that Kara would "mix it with mud" because of their different views. Olivia Marsdin gave her speech and was about to sign the decree, when she was attacked again. The culprit turned out to be Scorcher, who managed to escape. Later, Alex found out the factory warehouse was where the criminal was hiding and she, along with Kara, arrived at the place and managed to defeat her. The next day, Kara apologized to the alien from Daxam, Mon-El, for having treated him biased due to the fact that her people considers Daxamites a race of bullies and hedonists, and for the fact that she accused him of the attempted assassination of the President. After that, he introduced himself as Mon-El and said he wanted to send a signal back home, but Kara was forced to tell him that Daxam had expired after Krypton's explosion.

Kara joined Alex and Detective Maggie Sawyer to a crime scene, where she helped establish the deceased alien was killed by another alien. Later, she went to work and told Snapper the news, but he refused her article, as she did not have any official sources. Later, after Alex and Maggie found the underground alien fight club, Kara arrives to back them up but, after the ringmaster, Roulette, released Draaga to fight against her, she was quickly overcome so Alex and Maggie shots into the air to disperse all the present forcing Draaga and Roulette to flee. Later at the D.E.O. Kara and Alex told J'onn that they have see M'gann M'orzz at the club. Kara once again went to Snapper with news regarding the fight club, he immediately became interested, but as soon as he learned that Kara again had no source, and only unofficial statements, he says that as long as she does not indicate her sources he can't publish her articles. In the evening Kara stopped Roulette's limousine and told her that she will stop her illegal fights, to which Roulette replied that her club does not violate the law, as aliens are not people, and therefore they have no rights, pointing that on the contrary, she is giving them a place where they can "find glory and earn money". Roulette then told her that she could try to stop the matches but wouldn't stop them for long as she is offering her fighters more than Kara could.

The next day, in D.E.O., Kara wonders if Roulette might have been right about Kara offering nothing to aliens but Alex tells her that Roulette only offers fear and she can give them more than that. Kara then learns that Mon-El had left the D.E.O. with Winn, without permission, and had accidentally injured some people in a bar. She goes to speak with Mon-El about their powers, and about her parents and what they were. Before she left, he told her that he had heard about her fight with Draaga and that he'd seen him fight years ago with the Daxam Royal Family. He told her that during that battle a sword hit him in the right leg, making it his weak spot. The next day Kara learns from Alex that J'onn and M'gann were kidnapped by Roulette and, after she obtains from Lena Luthor the new address in which Roulette will host the battle, Kara comes to it and managed to defeat Draaga. Then she explains to the aliens that Roulette is in fact their enemy, so they agree and let Alex and Maggie arrest her.

The next day Kara comes to Snapper and gives him an article about the fight club, which has an official police report, criminological analysis and comment from Supergirl. He takes the article, but asks to correct some errors. Then she comes to the Mon-El in D.E.O. and she tells him that she was sent to Earth to protect and educate her cousin, but she was unable to fulfill this mission, so now she will train him.

Kara asked Winn to make Mon-El a fake ID as "Mike Matthews", and arranged him a job as a CatCo intern. They come at the office together and Kara introduces him to Eve and James, whit whom she later go to take a coffee, encountering a gang of criminals armed with alien weapon that Kara unsuccessfully tried to stop from robbing a bank and escape. Back in CatCo, Kara learns from Eve that Mon-El asked her to do the work that James had given to him, so she approaches him and explains that he has to do his job. At this point, Lena Luthor comes to CatCo and invites her to a charity event to raise funds for a children's hospital. Then Kara is called Alex, who told her about another robbery, Kara arrives on the scene, and one of the gang members with the help of anti-gravity gun sends a police car in the sky. Flying behind the car, Supergirl managed to saves the policeman, then she returns to CatCo and found Mon-El making out whit Eve. Angered, she tells him that she tries to help him fit but he spoils everything, and that if he does not want to do anything he would look for another coach. Later Kara comes home and found Alex at her door, she tells her that she is in some ways confused but, seeing Kara upset, Alex immediately asks her what happened and the latter responds that Mon-El did not perceive the work seriously. Alex advises Kara to let Mon-El find what he is interested; after that, Kara asks Alex if she was going to say something, but before she can speak, Lena came to Kara's apartment and asked her to arrange a meeting with Supergirl. In the evening, Kara arrives at the L-Corp in the guise of Supergirl and Lena invited her to her charity party in the case of gang attacks. The next evening, Kara and Winn arrive at the charity event, where Kara supports two conversations at once with Lena, both as Supergirl and in her civilian identity, by rapidly changing clothes. After a while, Kara meets Mon-El at the party and he invites her to dance, then the gang of criminals armed with alien weapons broke at the party and start a struggle with Supergirl. At this point, Lena and Winn were able to establish a black burst generator, destroying the criminals' weapons so that they were captured. The next day Kara comes to Mon-El and says that he was fired, then she tells that she will not force him to live as she sees fit, and that he can find what he likes. In the evening Kara, in the guise of Supergirl, flew back to Lena thanking her for her help.

The next night, Kara and Mon-El sat at the alien bar, and she told him that he should find a job and start training with her, however he ignore her advices and offers her an alien cocktail which got Kara drunk for the first time in her life, so Alex and J'onn took her at the D.E.O., where she fell asleep. The following morning, Kara trains with Mon-El to teach him how to "change the world" and become a hero (also taking the chance to getting her revenge on him for what happened the previous night). At this point, Alex asks Kara to talk in private, and they went out into the street. There Alex admitted to Kara that she is a lesbian and that she has feelings for Maggie; to which Kara results a bit shaken. In the evening J'onn sent Kara and Alex in the National City University to arrest doctor Rudy Jones, who was infected by an alien parasite. However, as Kara hit him, he grabbed her hand, sucked out of it a part of her life forces and escaped. The next day, at Kara's apartment, she told a visiting Alex that she understands how it feels to keep part of themselves locked away; she encourages Alex to pursue a relationship with Maggie if that is what she desires. Later in the city center, Kara discovered that Mon-El has found a new work as a loan enforcer, and in the heated conversation that followed, she told him she was disappointed and that he was no hero, and in turn he told her she was not really altruistic, but rather an attention seeker. The exchange left both disheartened. In the evening, J'onn and Supergirl confront Parasite, who defeat them simultaneously sucking the life forces of them both; then they are rescued by Alex and taken at the D.E.O., where Kara quickly recovers thank to solar radiators. meanwhile, Parasite terrorizes National City and is faced by Mon-El and the Guardian until Supergirl arrives and, after offering to him one last chance to surrender, she completely obliterate him by using plutonium from a nuclear power plant. Then she thanked Mon-El for what he has done, and the unknown armored vigilante, whose costume is partly made of lead and so she could not see who is underneath even with her X-ray vision. The next night, Kara came to Alex's apartment to talk to her, but she did not open the door; worried, Kara entered from the window and Alex, weeping, told her that Maggie has rejected her. Kara hugs her and begins to comfort her.

Medusa virus
After Mon-El was captured by a bunch of Cadmus' agents who deliver him to one of their hidden bases, putting him in a cage, Supergirl is informed by Cadmus at a special frequency that they have the Daxamite and promised to kill him if she did not come. When Supergirl arrived in Cadmus, she met the real Hank Henshaw, revived as a cyborg, who was able to overcome her and imprison her in the cell next to that of Mon-El. Here, Lillian Luthor revealed herself to Supergirl as the leader of Project Cadmus and threatened to kill Mon-El, if she does not deprive herself of solar energy with the help of a special device; despite Mon-El's pleas for Kara not to do it, she was forced to agree, then Lillian slapped her and took her blood for the purpose of obtaining information on "Medusa" before to sent her back to the cells. Left alone in the cells, Mon-El and Kara bonded and discussed their fears, and what happens if they do not live through this ordeal. Fortunately they were rescued by Jeremiah Danvers, who had access to Cadmus IDs, and chose to remain behind for unknown reasons. Later that night, Kara, Mon-El and their friends celebrated their return in Kara's apartment and she informs Alex that Jeremiah is alive and well; then she told Mon-El he was brave throughout the ordeal, to which he replied any courage he had, he learnt from her. Preparing for Thanksgiving dinner, Kara helped to cook the turkey using her heat vision. She soon after walked over to Winn and James, the former of whom claimed to not be able to wait for Eliza's glazed carrots. She answered the door to Mon-El, who came bearing flowers and mattress stuffing, having mistaken food stuffing for the latter. She introduced him to Eliza, who hit it off right away with him. When she asked her mother about this, thinking he was hitting on her, Eliza voiced her belief that he was doing this in order to impress Kara, as he in fact liked her. Later on, as they sat down for dinner, they expressed what they were thankful for. Before Alex could come out, they were interrupted by a breach. The following day, Kara, Alex and Winn all headed to work at the D.E.O. Hoping to find out what Lena Luthor knew, Kara headed for L-Corp under the guise of writing a piece for CatCo. However, their interview was cut short. The day after, Kara visited a contained Mon-El, who had come in to contact with a toxin released by Cadmus. Due to its targeting of aliens, she was forced to stay at the D.E.O. Kara and Mon-El played Monopoly to pass the time, before Kara questioned whether Mon-El had feelings for her. He ambiguously denied it, before collapsing in a coughing fit. She opened the cell, seeking medical attention. Deducing that the virus was from Krypton, Kara further deduced that Cadmus had used a sample of her blood to get into the Fortress of Solitude, thus obtaining the virus. Kara traveled to the Fortress, where she was greeted by a reprogrammed Kelex. He attempted to kill her, but she used her heat vision to destroy him. Using the Fortress' computers, she was greeted by a hologram of her father, who explained the virus, Medusa, to her. Returning to the D.E.O. with all of the information she could, Kara sat by Mon-El's bedside, before later reminiscing of her life on Krypton to J'onn, admitting that her parents were not who they seemed. Suddenly, J'onn was struck by an immense wave of pain, showing his oncoming White Martian form. He explained what had happened with M'gann's blood transfusion, believing there to be no cure. Soon after, Supergirl headed to L-Corp, taking on Cyborg Superman. When another breach was opened for a moment, Hank was distracted, allowing Supergirl to gain the upper hand, but he escaped. Kara returned to the D.E.O. with an injured Maggie Sawyer, before she went to talk to Lena. She explained her mother's role in Cadmus, but Lena refused to believe her. Kara, distraught that her family had caused Mon-El's condition, went to sit with him as he woke up. The two kissed, before Mon-El returned to sleep. Later on, Supergirl and J'onn left to the National City port, where Cadmus planned to release Medusa via air. With Lena at the rocket's controls, Supergirl begs her not to launch it but the former justifies as she is "a Luthor". While J'onn took on Cyborg Superman, Kara went after the rocket with the virus. As she caught up with it, Lillian Luthor detonated it. With the virus having been made inert, with no risk to any alien, she returned in time to knock out Cyborg Superman and save J'onn. Back at the D.E.O., Mon-El woke, fully recovered thanks to Eliza's reverse engineering of a living sample of the virus. Kara questioned if Mon-El remembered anything they'd discussed, but he played coy. The following day, Kara returned home with a number of bags to find Barry Allen and Cisco Ramon, wishing to have a favor repaid.

Assisting with the Dominators
Arriving on Earth One in order to help against the Dominators, Barry introduced Kara to everyone, before they all trained against her, much to everyone's losses as they realized her near-invincibility. Barry later appeared, telling everyone that because he created Flashpoint, he had screwed up everyone's lives, and asked to not be trusted, instead staying behind with Oliver. Kara and the other heroes arrived at the salt mine where the Dominators were. A trap was set in place, causing them to be mind controlled and turned against The Flash and Green Arrow. With the Flash's quick thinking, he led Supergirl to the salt mine and tricked her into destroying the mind control device, freeing everyone. As a precaution, Supergirl scouted around Central City and made sure there weren't any more of the devices.

Supergirl and The Flash headed to Star City to assist Team Arrow's recruits in taking down Laura Washington, a scientist who stole a completed prototype of a regulator, something the team needed to decode their alien technology. She double-teamed with the Flash and took down Washington in a flashy technique, thus earning the praise of Rene, who had previously despised them. When the Dominators threaten to release on Earth a bomb that would end every meta-humans life along with millions of human lives, Supergirl and The Flash raced around the world planting the device Lily and Martin Stein made that would put the Dominators in excrutiating pain on every Dominators on Earth. When Felicity activated the devices the Dominators were in extreme pain and once Firestorm transmutated the meta-bomb into water the Dominators retreated leaving Earth. After the heroes beat the Dominators, Kara took part to their celebration party and suggests the new President of U.S. of Earth One to found their version of the D.E.O., prior to return to her Earth using an interdimensional extrapolator given to her as a present by Cisco to allow her to travel between their universes any time she wishes.

Back to her dimension
Around a week after returning from Earth One, a grieving mother came to CatCo seeking help from Snapper Carr on finding her daughter, Izzy, who had disappeared. Though Snapper appeared unsympathetic, Kara eagerly decided to assist. She sought out Maggie Sawyer at the alien bar, gaining information about a suspicious clinic offering monetary rewards for blood tests. Together with Mon-El, who learned of her quest and decided to help, they investigated the clinic under the disguise of a couple of millennials. Soon they discovered the personnel there are in fact aliens and Kara pursued them through the portal that connects Earth to their planet. Despite being told to get help, Mon-El decided to follow her, a good decision as he was able to save her from a sneak attack from one of the aliens, however they found themselves stranded on a planet with a red sun and, therefore, they're both powerless. While Mon-El wanted to retreat, Kara insisted they press on with the mission regardless. Spotting a fortress which they determined to be the aliens' base of operation, they headed towards it only to be ambushed by a local harmless hermit, Jo, from which they learned they're on Maaldoria, the "Slaver's Moon", a hub of sentient trafficking. Kara and Mon-El were able to infiltrate the slavers' fortress by feigning surrender, and afterwards they encountered Roulette, who was partially behind the operation. They also discovered the missing humans, and with them were soon sold to a Dominator. After Kara had a talk with Mon-El about heroism, the slavers ordered the group to start moving. Kara, despite having no powers, attempted to block them from taking the others, only to be hit with electric shocks. As the slavers repeatedly tortured her with their weapons, the others, seeing her in agony, were moved by her sacrifice and seized the opportunity to disarm the slavers moving together to escape. They were then helped out of the fortress and taken to the portal by Alex and the strike team that she had assembled. Later that night, Mon-El went to Kara's apartment and tells her he has decided that he wanted to be a superhero on Earth just like her.

Kara started Mon-El with his hero training at the D.E.O. and after a few trials, it seemed like he might be ready to head out to the field. At that time, Livewire had escaped from prison and although Kara is greatly upset about her nemesis being at large, Mon-El was excited to help her track down the villainess. When the police were attacked by two people with Livewire's powers Kara and Mon-El went to stop them. Kara told Mon-El to stay and protect the officers while she fought the Livewires. Mon-El shielded them from the lightning but when he saw that Kara was starting to be in trouble, he left the officers to try and save her. He accidentally deflected a lightning blast to one of the officers but luckily Guardian had been there to absorb most of it with his shield. After the Livewires retreated, they saw that Guardian was really Jimmy Olsen and Kara has a massive fight with him as she disapprove the risk he is taking, however he reminded her she is not the one who decide who can be an hero and angrily leaves. Later Kara confronted Mon-El with abandoning the officers and he defended himself stating that he saw she was in trouble. However, Kara asked if the real reason that Mon-El was doing this was for her, which Mon-El just left her without answering. Later, it was revealed that Livewire had been kidnapped by a scientist to make Livewire soldiers and Kara felt guilty for not having think about it because of their past together. Meanwhile to prove their value in Kara, with the help of Winn Mon-El and Guardian track down Livewire's copies and the scientist who created them but they're both subdued. Later Winn revealed their location to Kara an she arrived to help free them and Livewire and together the four stopped the scientist and his soldiers. As Livewire was about to kill her former captor, Supergirl moved to reason her not to do it but letting him go to jail insisted, to which Livewire agreed after Supergirl promised not to look for her until after the scientist was locked away, then Livewire left her, promising to return. That evening, Kara told both James and Winn that she had always seen them as heroes even before they became vigilantes and that if they intended to continue she will neither stop nor support them, however they claimed they will not stop. Later Mon-El visited Kara at her apartment and confessed that he remembered kissing her when he was sick. He also told Kara that he saved her during the attack because he cared about her. Though he said that he understood that she might not feel the same way but he asked Kara to still work with him and help him become a hero. As Mon-El left the apartment Kara was speechless and both of them were left awkward and flustered.

Kara had an awkward conversation at the alien bar where she attempted to smooth things over with Mon-El while justifying why she apparently didn't like him. After he left, feeling emotionally unwell, she found Alex and intended to discuss plans to celebrate the day she arrived on Earth to alleviate her stress, however Alex had other plans with Maggie and proposed to postpone the event; despite being visibly hurt, Kara wished Alex a good time. Outside, M'gann confronted J'onn about following her around in different disguises, while J'onn explained it was for her safety against a White Martian attack. That proved to be true in the midst of their conversation as Armek emerged to attack them. Kara arrived outside to intervene and drove Armek away. J'onn decided to invite M'gann to the protection of the DEO headquarters. Kara was present with others in the building when Armek impersonated M'gann and attacked. J'onn sealed the structure to prevent his escape as the group devised means of identifying who Armek may be impersonating next. After a flame test it was revealed that Armek impersonated Winn, and he escaped after a brief fight with Kara and J'onn. J'onn deduced the real Winn must also be in the building, and the group discovered the reactor of the building has been set to explode. Kara alongside Alex searched for the real Winn, and she revealed her feelings to Alex on the way. However it was soon revealed there was a second White Martian, and it has impersonated Alex. Kara was able to defeat this one after a long fight, while Armek was killed by M'gann. The real Alex experienced their conversation through the Martian's telepathic bond and went to Kara's apartment to talk to her. The sisters made peace and celebrated Kara's Earth Birthday together. However Alex also deduced Kara wanted to devote lengthy plans to her celebration to distract away from other emotional stress. While reluctant at first, eventually Kara admitted she in fact has feelings for Mon-El. Under her sister's encouragement, she decided to confess her attraction to him. She encountered him at CatCo the next day, but as she was about to speak to him about her feelings, Mon-El revealed he was on a date with Eve. As the two left, Kara was once again alone feeling disheartened.

Vindication of Lena Luthor and feelings for Mon-El
After Lena betrayed her mother and caused her arrest, Lilian was on trial for her various acts of terror. After learning of this Kara felt like she should speak to her friend in this time of need. She encouraged Lena to visit her mother in prison, which the latter did. Shortly after her visit however, Metallo was secretly given back his kryptonite heart by a Cadmus agent and, during the hearing, after being brought as a witness, Metallo attacked the people gathered at the court. Supergirl intervened but was unable to apprehend either Metallo or Lilian who he helped escape, as Metallo destroyed a nearby crane forcing her to save people instead. As the empowerment of Metallo occurred during the same time as Lena's visit to her mother, suspicions fell on her as the instigator. When video evidence was found of Lena retrieving kryptonite, she was arrested by Maggie Sawyer. Despite all her friends, including her sister and J'onn all believing Lena was guilty, Kara refused to believe her friend abandoned the side of good. This caused a minor rift between her and James, who told her the similar story of Superman and Lex Luthor. While at CatCo, Kara also encountered Eve and asked her about her date with Mon-El. She learned that Mon-El still had feelings for her as during his date he spoke about Kara the whole time. Upon Kara's insistence, Winn examined the footage evidence and discovered it was in fact Hank Henshaw who retrieved the Kryptonite. Now vindicated in her belief in Lena, she flew to Lex Luthor's mountain base, where Lena was held by her mother. Despite being briefly incapacitated by a sonic device and once more overpowered by Metallo, with the help of Martian Manhunter she was able to rescue Lena from her captors. Metallo's kryptonite heart had become unstable, and despite Kara's pleas for him to save himself, he exploded with the facility. Lena thanked Kara in her office and their friendship was reaffirmed. Kara also mended her friendship with James, inviting him to a game night. At her apartment that night, she met with Mon-El, to whom she confessed her attraction. The two moved to kiss, and it seemed that after a long time Kara could at last be happy. At that moment however they were interrupted by Mr. Mxyzptlk, who materialized out of nowhere and proclaimed his love for her.

Mxyzptlk immediately conjured and filled Kara's apartment with flowers and a concerto before he quickly told Kara again that he was in love with her before he was grabbed by Mon-El. Mxyzptlk then banished Mon-El away before he told Kara that he wanted her to marry him before placing her into a wedding dress. Kara quickly and gently told him that she was flattered but she wasn't going to marry him. However, Mxyzptlk thought she was just playing hard to get and told her that he liked a challenge. She went back to the D.E.O. and learned from both J'onn and Mon-El that Mxyzptlk was a fifth dimensional being with powers bordering on magical. When she and Mon-El were alone, they agreed that their moment was nice and wanted to spend Valentine's Day together. Kara then went off to stop some bank robbers but Mxyzptlk arrived and took their guns away. Then, he quickly had them turn and point to shoot at the robbers and Kara quickly went to save them before they could get shot. Alex then came to see her and seemed to be worrying about Maggie and her aversion to celebrating Valentine's Day with her and Kara told her to try surprising her when they saw that Parasite was attacking the city. She and Mon-El rushed to stop him but it was revealed that he was an illusion conjured by Mxyzptlk to try and show off his powers to Kara. Mon-El then angrily told him that he should just say his name backwards and leave Kara alone and she was surprised that was the way to get rid of him. She then sent Mon-El away to try and talk to Mxyzptlk but he told her that unless she agreed to marry him, he would keep unleashing chaos upon National City. Kara then confronted Mon-El about him not telling her about the whole saying the name backwards thing but he told her that he didn't tell her because it never works as it was impossible to get him to say it backwards as Mxyzptlk wasn't stupid and the best way was to kill him. Kara refused to do that and Mon-El accused her of loving the attention that he was giving her as well as with his power. Kara tried to come up with a way to try and get Mxyzptlk to say his name backwards but was starting to think Mon-El was right as she couldn't think of a way to do it. J'onn told her that they found something that might work on beings like him but saw that it was missing and she realized that Mon-El took it. She quickly found the two fighting and arrived just before Mon-El could be shot with a lead bullet. She quickly told Mxyzptlk that she would marry him to the surprise of both men. She told him to meet her at noon in the Fortress of Solitude as she wanted to wear her mother's dress. Mon-El later visited her to find out why Kara was doing this and she told him that the two of them wouldn't work as they were just too different. Mon-El then left her apartment brokenhearted before she left for the fortress. Mxyzptlk arrived but was surprised to see her in her suit and not her mother's dress. She told him that she really brought him here to avoid him hurting people when she told him that she wasn't going to marry him. Mxyzptlk became enraged and then animated the ice sculpture of Jor-El to attack her but Kara quickly destroyed it. Mxyzptlk then said that if he wanted to he could send a crack half-way through the Earth and would follow her across the stars until she agreed to marry him. Kara agreed and then went to activate the self-destruct sequence for the fortress which would kill her. Mxyzptlk said that she was bluffing but Kara said she would rather die than let him keep terrorizing the Earth over her. He then begged her not to do it and she then went to show him the override code. He punched it in and stopped the detonation but it was revealed that the code was his name spelled backwards. He realized that she tricked him and was already starting to disappear. He told Kara that all he wanted was for someone to love him but Kara told him that love wasn't control or forcing someone to obey but about finding someone to be free with. Later, at her apartment, she called Mon-El to see her and she explained that she didn't mean any of the things she said to him. She just wanted to go through with her plan without Mon-El trying to stop her. She told him that she didn't need him to come to her rescue all the time and that she could take care of herself. Mon-El then admitted that he lost himself when it came to her as she had become his kryptonite. The two of them then started kissing and spent the rest of Valentine's Day together.

Return of Jeremiah Danvers
Kara woke early from spending the night with Mon-El, and performed various Super-heroics. She asked Mon-El to keep their relationship a secret before going to work at the DEO. Mon-El reneged on their agreement however and immediately announced to everyone their relationship. Before she could speak with him about this however DEO intercepted Cadmus movements. Kara and J'onn J'onzz intervened and easily defeated Cadmus forces. As Kara went to inspect their cargo however she was shocked to find her foster father inside. The rescue of Jeremiah was welcome news for everybody. He shared a tearful reunion with Kara, Alex, Eliza and J'onn. He told them Cadmus saved him so he could augment Hank Henshaw, and forced him to continue working for them afterwards. He also revealed Cadmus has constructed a bomb with which they plan to destroy National City. Mon-El had suspicions however and stated it was more than luck they found him. Kara with her family and friends hosted a dinner in celebration of her father's return, however Mon-El soured the event by once again raising the issue of his return being a trick. Kara angrily evicted him from her house, and Jeremiah saw him out, stating on the way that he knew who Mon-El was, and that Kara will not like the secret. Mon-El would not give up however and tasked Winn with being vigilant. Kara was forced to consider his position when Winn discovered Jeremiah infiltrating DEO systems. She confronted her father about this, to which he admitted and explained he was trying to learn about the time he missed with his daughters. Kara's suspicions enraged Alex, who accused her of not siding with family and being clouded by her new found relationship. Kara by now however has firmly realized something was wrong, reasoning that her father could have simply spoke with them to learn of past events. Mon-El was proven correct when DEO seemingly located the bomb. As Kara, Alex and DEO forces converged, they found nothing at the location. In the mean time, Jeremiah had retrieved DEO data, defeated J'onn with his cybernetic enhancements, and rejoined Cadmus. Kara and Alex arrived to confront them, however Cadmus sabotaged a train, forcing Kara to save people. Alex, left alone with her father who refused to surrender alive, could not bring herself to shoot him. Traumatized by their father's return and betrayal, both sisters grieved at home. Mon-El visited Kara's apartment and found her crying on the couch. She asked him to stay with her and they embraced. At that moment however Winn called and informed her Jeremiah had taken the Alien Registry, giving Cadmus information on every alien in America. Putting her grief aside, she and Mon-El jumped to action.

With Cadmus now in possession of the list, aliens were being abducted around the country. The D.E.O. couldn't track how and where Cadmus was taking them and it was suggested that Jeremiah was helping them stay out of their field of surveillance. J'onn then decreed that Jeremiah Danvers was now a high priority threat to Kara and Alex's discomfort. Kara wanted to try and warn everyone of the danger with an article but Snapper Carr refused to publish it without hard evidence. Kara attempted to get Snapper's help by promising an interview with Supergirl but after speaking to him as her alter-ego, he found that she wasn't a credible enough source as she couldn't reveal anything that tied her to the D.E.O. Later, Alex went to Kara as J'onn had removed her from the case and she asked Kara to talk to J'onn about putting her back on but Kara seemed to believe it was for the best as she was sure that Alex might get blinded by Jeremiah. Kara ran into Lena Luthor at Catco who was looking for her as they had made plans. However, Kara told her about how Cadmus had taken the Alien Registry and was now abducting the people on it. She also told her of her trouble of getting the word out to warn people and Lena suggested that she try posting a blog about it to try and reach the masses instantaneously. Lena also offered to look into her mother's activities to see if anything popped up. Kara had written her article but was nervous about posting it as she would be acting against Snapper. Mon-El asked if it was the right decision and Kara believed that it would be the best thing to do in order to try and alert people to Cadmus and so she posted it. She then got a phone call from Lena just as some of Cadmus' men were attacking her. Kara flew over as Supergirl and caught Lena as she fell from the building and handled the men. Lena then quickly told her about finding a warehouse that had been recently billed even though it was meant to be defunct which is where she believed Cadmus had taken everyone. Due to Kara's blog, Lillian Luthor moved to act on her plan sooner to take all the aliens they had gathered and banish them from Earth in a space frigate. Alex managed to find the warehouse as well and convince Jeremiah to help her. She stowed away on the frigate and notified the D.E.O. of the ship and they called Kara to help in keeping the ship from leaving the planet's atmosphere where it would then warp away to the other side of the universe. Kara moved to try and keep the ship from getting to the atmosphere but it was proving a little too much for her to stop. Alex tried to stop the thrusters and managed to shut the power down enough for Kara to stop the frigate. When Kara returned to Catco, she was met with an angry Snapper Carr who told Kara that her blog violated her contract. She defended her actions as she had been telling the truth about Cadmus' plot the entire time but Snapper told her that she was only lucky. He informed her that there was a reason why he requested such hard and concrete evidence and sources as one misquote or hole of information could lead to dangerous consequences. He told her that she was fired even though he had been secretly rooting for her. Kara was upset at losing her job and Mon-El tried to comfort her but Kara said that, for now, what she had as Supergirl and him was enough.

Mon-El, the Prince of Daxam and Attack of the Music Meister
Kara and Mon-El were hanging out in her apartment watching movies when Mon-El asked if they could try watching a musical. Kara loves musicals and was happy to recommend one when a transmission came over television from alien visitors demanding Mon-El be given to them. Kara was ready to stand in their way and went to confront the ship but they deployed their weapons against her. When she was fully locked on by the ship, Mon-El quickly sent the ship a message telling them that he would surrender to them and they laid down their weapons. Kara asked why Mon-El was surrendering to them and he told her that he wasn't worth innocent lives. He was getting teleported to the ship when Kara went to grab hold and teleport with him. On the ship, the people immediately bowed and Kara was introduced to Mon-El's parents. She was shocked to learn that his parents were King Lar Gand and Queen Rhea of Daxam meaning that Mon-El was the Prince of Daxam. They invited Kara to dinner and she and Mon-El learned that the king and queen had received his message though it was incomplete and had been searching the galaxy for him. They had heard about his exploits on Maaldoria which they claimed they were surprised about. Kara defended their actions of freeing slaves and fighting slavery though Rhea and Lar Gand argued of their support of slavery and that their treatment of their slaves was always decent. When Mon-El's parents wished to know of how he escaped, he tried to dodge the issue but Kara was insistent to learn the truth. He then revealed of how he had been taken by his guard to the Kryptonian pod that belonged to a Kryptonian emissary. His guard killed the man in anger as Krypton was responsible for the chaos and put Mon-El in the pod to get to safety. Kara then quickly excused herself to go back to Earth and Mon-El followed. Back at the D.E.O. Mon-El tried to explain but Kara was too angry to listen as Mon-El lied about who he was. She was mad that Mon-El turned out to be the prince of a planet that was cruel and unjust. Kara tried to find distraction in the fact that Winn was having trouble with his girlfriend Lyra, who apparently set him up in a robbery of a painting. She was eager to try and find her but quickly deflected bringing Mon-El when Jimmy suggested it. Alex pulled her aside and told her that she shouldn't be involved in the case when she was dealing with something that was strongly personal and needed to talk to Mon-El. Kara then admitted that she hated him right now and wasn't even sure who he really was. She was conflicted as Daxam was a party planet because the royal family of Daxam made their people that way to distract them from the oppression they wrought and Mon-El was now a part of that. A moment later, Queen Rhea appeared at the D.E.O. to speak with her. Rhea came to thank Kara for watching over her son but Kara knew that the queen didn't come just for that. She then asked for Kara's help in getting Mon-El to return with her and her husband to Daxam. She claimed that she needed Mon-El to rebuild Daxam and be the face of their people's future. Kara wasn't sure Mon-El would listen to her but Rhea said he would because he was under her spell. She also told her that she was starting to resent Mon-El for being Daxamite Royalty and it was the best for him to return because if he stayed on Earth he would only eventually learn that he wasn't good enough for her. Mon-El soon went to Kara when he tried to explain himself but Kara quickly told him about his mother's visit. She told him that his parents wanted him to return with them to Daxam but Mon-El refused. Kara told Mon-El to forget about them for the moment and take the time to realize that he was no longer the last Daxamite as he got his people, and his parents, back and not many of them get to have that. She told him that he was the prince so he should start acting like one. Later, Mon-El went to her apartment to try to repair their relationship. He apologized and claimed he never wanted to hurt her, but could not answer when Kara asked if he was ever going to tell her the truth. Saddened by this, she called an end to their relationship, and cried after he left. The next day, the DEO detained a new individual J'onn claims to be an alien. When brought to the DEO lobby, he declared he had been looking for Kara, and hypnotized her with his powers. Then, he stole her interdimensional extrapolator, and escaped to Earth One in pursuit of Barry Allen. On the outside, Kara had slipped into a comatose state. As for Kara, she found herself inside a nightclub where she was moved and made to sing on stage.

Unsure of what to do and seeking answers, J'onn and Mon-El travelled to Earth One arriving in S.T.A.R. Labs to warn The Flash of the Music Meister. There they met the rest of Team Flash and they agreed to help try and save Kara. However the Music Meister struck shortly after, and induced the same coma effect on Barry. Kara was singing Moon River when she quickly found Barry in the crowd. After she was done, she learned that she was on Earth One due to J'onn and Mon-El though she quickly told Barry that Mon-El wasn't her boyfriend when he suggested it. They tried to learn more when they ran into Cutter Moran, who was the counterpart of Malcolm Merlyn. He revealed himself as their gangster boss and demanded that Kara and Barry perform something original for his club. They also ran into Grady and Pablo who were Winn's and Cisco's counterparts and they realized that they were in some kind of musical world. The Music Meister then appeared and told them that he was in the real world and ready to wreak havoc and if they wanted to stop them, they would need to leave this dream world by following the script of a musical. After performing a number for them, he disappeared and they moved off to let themselves be captured.

The two were taken by the men of Digsy Foss, a gangster boss in the dream world that bore the likeness of Joe West. After a brief conversation with Barry in which she told him of her breakup with Mon-El and learned Barry broke up with Iris as well, they were tasked to find Millie, Digsy's daughter, in the likeness of Iris. They found her in an apartment making out with Tommy Moran, son of the man who own the club they "worked" at and Digsy's rival, who to her disgust was in the appearance of Mon-El. Believing the plot required them to help the two imaginary lovers reveal their romance to their parents, Kara went to help Tommy while Barry helped Millie. While explaining to Cutter that Tommy kept his secret for a justifiable reason, she realized the allegory applies to her own situation with Mon-El. After they got the lovers' parents to apparently accept their romance, Kara and Barry didn't understand why they were yet to be freed. They then remembered that Cutter wanted them to perform something original. The two then went on and practiced Super Friend with Grady to try and close out the musical.

However, outside the club, the Moran and Foss' gangs went to war, apparently not truly accepting their children's romance. She and Barry were shot while trying to mediate, and without their powers, laid dying. Mon-El and Iris entered their world with the help of Vibe, and Kara told him she forgave him. They were brought out of the dream world shortly after. The Music Meister stated he did this to them to teach them a lesson about love and how it just wasn't about saving people but letting themselves be saved sometimes. He then left them with that before he vanished. With her relationship with Mon-El somewhat mended, Kara returned to Earth Thirty-Eight with her friends.

Hunted
A new alien attacked National City the following morning as Kara and Mon-El were sitting for breakfast. Kara quickly flew in and defeated it easily but the DEO recovered a device on the alien indicating that a bounty of 300 Quartz Crowns had been placed on Kara's life. They all realized with the bounty in place, there would be series of bounty hunters and galactic killers coming to National City to take a shot at it but Kara wasn't worried. J'onn and Alex wanted Kara to lay low, arguing that even though Kara could take care of herself, a lot of damage could be done with bounty hunters attacking one after the other. Eventually, her friends were able to talk her down and she agreed to lie low for 24 hours to try and give them time to find who placed the bounty.

Kara had been placed on house arrest with James and Winn though she wanted to head out when she saw trouble on the news though they wouldn't let her. Mon-El then arrived and told them that he questioned his parents to see if they had placed the bounty to convince him to leave, but they denied involvement. Suddenly, Mon-El froze in his movements before he charged for Kara and then started to attack her on a rooftop across from her building. He yelled that he wasn't in control of his body and it was acting by itself. It turned out that a telepathic bounty hunter was the one controlling Mon-El to attack her. Kara held him off until the bounty hunter was surprised and detained by Winn, pretending a stapler was a weapon. They took him back to the D.E.O. but he told them that he wouldn't talk. J'onn interrogated the new attacker with mind powers, and confirmed the bounty had indeed come from the Queen of Daxam.

While Kara was cleaning the mess from the last attack at her place, Mon-El suggested that the two of them run away together off world in order to get away from his parents but Kara refused to run. Mon-El knew that Kara would say that but didn't know how to stop his mother. Kara suggested she and Mon-El speak with Rhea, believing that they can convince her to understand that he had made his choice and is happy on Earth. Mon-El was against it but she ultimately convinced him to try. The two met with Rhea in the Fortress of Solitude, and following a cold exchange, Kara attempted to reason with her, saying she believed there was kindness in the Queen. Rhea told Kara that anything that Mon-El found on Earth with her was a lie and it was now over. Kara then started to feel weak and Rhea visually drew two kryptonite daggers and stabbed her. Seeing that his mother is intending to kill Kara, Mon-El agreed to return to Daxam in exchange that she be spared.

Kara returned to the D.E.O. and quickly told Alex and J'onn what had happened. She wanted to rescue Mon-El, but J'onn had orders from the President not to engage the Daxamites for fear of an intergalactic war. She appealed to her friends and was able to convince them to help. Winn repaired the portal from Maaldoria to teleport to the Daxamite ship, and J'onn in the disguise of Kara travelled aboard, defeating Daxamite guards and Rhea as he was immune to kryptonite. Winn rescued Mon-El while the real Kara also arrived when J'onn was getting overwhelmed. Lar Gand fought with J'onn while Kara held off Rhea, but being severely weakened by kryptonite she was at a disadvantage. Before Rhea could fatally strike her, Mon-El broke a ship window and the kryptonite weapons were sucked into space. Seeing no point in further fighting and resigning to his son's wishes, Lar Gand ordered the Daxamites to stand down, much to Rhea's anger.

Kara and Mon-El returned to Earth and shared another romantic moment. Knowing that they would each sacrifice to save the other, their bond became closer. Rhea was enraged that Lar Gand gave up, and murdered him. She then vowed vengeance on Earth.

Reporting again
Kara had come to the D.E.O. ready to fight bad guys but J'onn, Alex and Winn told her that everything in the city was quiet right now. They all left to go do their own things and Kara was left wondering what she would do. She went back home and tried to bake danishes but burned them. She was then visited by Lena who asked her to come with her to a presentation being hosted by Jack Spheer. She told Kara that she and Jack had worked together for years before she moved to National City, and even had dated the final two. However, they broke things off and she was a little nervous about reuniting with him as she felt he was her "kryptonite". Kara agreed to come and report the event for her blog.

When they arrived, she had awkwardly run into Snapper Carr. Snapper sarcastically asked what she was doing there as he didn't know that dotcoms counted as a press pass now. Kara told him she was just there with a friend and tried to snidely talk back to him, unsuccessfully. Jack Spheer then came on stage with his company's CFO Beth Breen and presented his new product: Biomax. He then cut his hand and had the audience watch as his Biomax nanobots move in and heal it. Lena told Kara that she and Jack were working on it for years but it seemed that he had gone on to perfect it. When Spheer called for questions from the audience both she and Snapper were the first ones to stand. She started to ask a question, somewhat hesitantly, which encouraged Snapper to try and cut in on her. However, that seemed to harden Kara's resolve as she then unflinchingly asked if Jack was following the proper health code regulations in introducing the Biomax to National City.

After the presentation, Jack Spheer approached her and Lena. Kara saw that the two of them had a lot to talk about so she left them to do so in private. On her way out, she was pulled aside by a man called Joe Watkins. He told her that she was the only one he could trust and that he had information on Biomax and if she was interested then she would meet him later that night. Kara went to the lot where she found Joe waiting in his car and went inside. She asked why was he going to her and he explained that she had warned everyone about Cadmus' plot against aliens so he could see that she wanted to do the right thing. He told her that he worked at Spheerical Industries but had been fired when he had found that there was no records of any of the human trials done with the Biomax. He told her that the Biomax wasn't safe to use and that Jack Spheer was releasing it anyway. Before anything else could be said, Kara heard a noise just before the whole car exploded. She escaped relatively unscathed but Joe had been killed.

She went to James for his and Catco's help in trying to stall the launch of Biomax but Snapper put a stop to it as he reminded Kara that she no longer worked there and couldn't use Catco resources. Kara then excused herself but then overheard Snapper telling James that he had a lead on Biomax and was going to speak with someone that was one of the test subjects. She followed him as Supergirl to the home of Derrick Simmons and listened in on them. Simmons told Snapper that even though he was listed as a test subject and paid for it, he never actually underwent any tests. Before he could say more, Biomax nanobots came into the apartment and attacked them. Simmons was eaten away by the swarm and it then moved to go for Snapper. Kara burst in and froze the swarm with her freeze breath before she took Snapper away before the swarm could break free. Kara went back to her apartment where Mon-El was waiting and she told him about how the source was just eaten by the nanobots and she had no further leads about Biomax. Mon-El then told her that Jack Spheer was having dinner with Lena and she had called Kara to try and help her get out of it. Kara then took Mon-El to go and get more information. They arrived at the restaurant to the surprise of both Lena and Jack. Kara tried to ask Jack some more questions but Lena cut in and asked if she and Jack could be left alone. Kara understood and moved for Mon-El to leave with her. Mon-El gave Jack a goodbye hug before he left with Kara and he revealed that he had swiped his security card so that they could go into Spheerical.

Kara and Mon-El used the card to go into Jack's office and Kara managed to decrypt his password and get into his files. They found that there were indeed no human test trials but did find a separate file that had a video of Jack using the Biomax on himself. His body had fused with the Biomax nanobots which meant that it was him that had killed both Watkins and Simmons. Kara moved to copy the video before she and Mon-El quickly left the office when they heard the Biomax swarm approaching. Kara went to Lena at her office in L-Corp and told her what she had found out about Jack. Lena couldn't believe it until Kara showed her the video of Jack. Lena then asked if she had told anyone about this yet and Kara said she hadn't. Lena then asked to hold off on it until she found out what was going on with him. However, Kara decided to go over to Snapper and deliver the information she had from Watkins. She then told Snapper that he was right to fire her for going over his head and that she had been lucky with Cadmus but had been so caught up with trying to warn people that she disobeyed the rules. Snapper then shared with Kara that after his source had been killed, he did some digging and learned that the one that signed the checks for the human testers was Beth Breen and if Biomax fails then she would lose everything. With that, she then moved to go to Spheerical where she found that Beth had complete control of Jack and was about to inject Lena with the nanobots to take control of her as well. Beth commanded for Jack to attack Kara and he unleashed himself on her as the Biomax swarm. Lena saw that Kara was in trouble and moved to try and shut down the company's server to deactivate the Biomax, fighting off Beth along the way. She managed to shut the nanobots down but since they had merged fully with Jack, he slowly died in front of both Kara and Lena. After Beth was arrested, Kara went to Lena to try and comfort her and Lena told her that there was a part of her that was glad that Beth was going to suffer in prison for what happened to Jack. She then wondered if she would end up like the rest of her family as this was how her mother had been like during her brother's trial and Kara told her that she wouldn't.

Kara then went to visit Snapper and thanked her for not smearing Jack's name as he had been the victim of Beth's greed. She gave him a danish that she had finished baking and Snapper then gave Kara a copy of the magazine. He told her to look at the byline and she saw that he had credited her alongside him. Snapper told her that Kara's interview with Watkins had been instrumental in Catco scooping its competitors with the story which is why he shared the byline with her. Snapper then told Kara that she was being offered her job back as Kara kept digging and trying to get the story even though two sources were killed. He told her that Catco needed reporters like that and Kara was happy to accept.

Alex's kidnapping
When Kara learned of a bank heist that had hostages involved, she quickly flew and crashed into the building, taking them by surprise. She quickly subdued them and brought them outside to be arrested. She ran into Maggie who was feeling annoyed that she had just charged in and wasted all the time that she was using to try and reason with them. Kara and Mon-El met up with Maggie at Alex's apartment for dinner. Kara believed that she did the right thing in stopping the thieves before they could hurt any of the hostages but Maggie told her that she was being too reckless. She told Kara that while her methods work on super criminals, many normal human criminals that she was catching were starting to use what was called the 'Supergirl Defense' in order to get through trial. She said that her way of charging in with her powers ended up leaving a giant hole in an architectural landmark and she didn't even ask or look to see if she should get involved. Maggie then warned her that she couldn't punch or fly her way out of everything though Kara believed that Maggie was being a sore loser. She and Mon-El then left.

The following day at Catco, Kara ran into Maggie who asked if she'd seen Alex. Kara had believed that she had stayed over with her but Alex had apparently tried to catch up to try and talk to Kara after she left and hasn't been seen since. She also told her that Alex hadn't checked in with the D.E.O. either. Kara then got a call from Alex's phone but when she picked up, a mystery voice answered and told her that he knew she was Supergirl and had Alex. He told her that Alex would die in 36 hours if she didn't break a man named Peter Thompson out of prison. The two went to the D.E.O. but they were unable to track Alex's location and couldn't find any leads on where Alex could've been taken to or by whom. Kara, Maggie and J'onn went to the prison to visit Peter Thompson to find out if he knew anything. Thompson claimed to not know anything about who would want to have him freed but Kara angrily demanded that he tell them what he knew. J'onn then told Kara to calm down and dismissed Thompson as he had read the man's mind and found that he was telling the truth. Winn then called and found that visitor logs and surveillance footage show that Thompson had a son called Rick Malverne and he found where he lived. Kara recognized the name as an old classmate of her and Alex from Midvale and quickly flew there. She found surveillance of Alex in full display and quickly found Rick. Kara told him to let Alex go but Rick told her that he wouldn't do that until she broke his father out of prison like he wanted.

Kara took Rick back to the D.E.O. where he was then interrogated by both Kara and Maggie. Rick revealed that he knew Kara was Supergirl from back in Midvale when she had saved that mother and child from the car crash. He remembered it and Kara from before she wore glasses and when Supergirl showed up in National City, he had put all the pieces together and knew it was her. He told them that he had been watching them and preparing for all of this for a year. Kara asked what had happened to Rick, as she remembered that he was a nice person that had a crush on Alex, and he told her that he really had a rotten childhood with an abusive mother. He then had learned about his father Peter who had then taken him away from Midvale and always did what he could to take care of him and even helped to send him to college. Maggie pointed out to him that Peter killed two people but Rick said they deserved it and if they wanted Alex back then Kara had to free his father within the next 24 hours. He then let them speak to Alex and she told Kara to not do what Rick wanted as Supergirl was bigger than her. When they managed to find where the signal was coming from, Kara quickly moved to get to Alex though Rick told Kara not to go there. Kara then flew over but found that it was a decoy and it triggered a trap that made the holding area where Alex was start to fill with water, cutting her time to only four hours.

Kara was then approached by J'onn and she told him that she was scared and felt powerless. She then admitted that Maggie had been right and there were things that not even she could punch or fly her way out of. They then noticed that Maggie was gone and she had went off to the prison to free Peter Thompson herself. Kara quickly flew there to stop Maggie and tell her that she couldn't do this. She then tried to reason with Peter and tell him what his son was doing. She told him that despite what he had done, he had been a good father to Rick but if he killed Alex then he would never get back from it. Peter then told the two where he believed that Rick had taken her. They went over there and found that Alex's cell was full of water and Kara quickly went and broke through it to get Alex out. They were relieved to find that Alex had used her training to try and buy them more time to find her. Alex was then taken back to the D.E.O. where they learned that J'onn was going to wipe Rick's mind of Supergirl's identity and the D.E.O. Alex agreed and then punched Rick in the face to the amusement of Kara and her friends. Maggie then thanked Kara for stopping her from making a mistake but Kara told Maggie that she merely reminded her of what she had told her before of not always being able to charge in with her powers and that she had been right. Then they shared a hug.

Daxamite invasion
Kara met with Lena for lunch where she revealed that she was working on a new energy project and she was hopeful that it would work soon. She wished Lena luck before she got an alert of an alien attack in the city. An alien with telekinetic powers was running amok and had started throwing people and vehicles about she moved in to save some of the people. Her actions were seen by James, who was starting to feel unaccomplished as Guardian. When Jimmy found the son of the alien from the attack, Marcus, he brought him to Catco to try and find his mother. However, Marcus started to act bizarre and started to unleash his power much like his mother did earlier in the city. Kara then moved to take Marcus away so he wouldn't hurt anyone and found that he had been in some kind of pain. They learned that Marcus was a Phorian and could be affected by energy shifts in the atmosphere. Kara remembered that Lena was working on a new energy project and went to call her but was surprised when Rhea picked up the phone.

Kara warns Rhea to not hurt Lena though she explains that Kara hurt her first when she turned her son against her. Rhea then tells her that everything that is about to happen will be her fault before she hangs up on her. When the D.E.O. tracks another energy shift, Kara, J'onn and Mon-El go to the source in order to confront Rhea. The source of the shifts was a transmatter portal that Rhea had tricked Lena into building for her. At first, Kara attacks Rhea but then she moves to try and shut down the portal. However, Rhea had rigged it to be self-sustaining and Kara tried to find a way to turn it off. J'onn tried to stop Rhea while Kara went to stop the portal but she used a device that she picked up from the White Martians to render him catatonic and experiencing psychic pain. Nothing Kara did worked and she then saw ships begin to emerge from the portal by the hundreds. They were Daxamite ships and were answering a call from Rhea to help her conquer Earth as she took Mon-El and Lena with her to her flagship.

Kara headed for the D.E.O., which was under attack by Rhea's forces. Alex had jumped out of the balcony as she was fighting the Daxamites and Alex caught her before they headed to the Alien Bar as their fallback spot. Kara met up with Winn and James, who had tried fighting some of the Daxamites in the streets. Maggie also found her way to the bar and told all of them that the police had been overwhelmed. Kara guessed that her cousin was on his way, if not already in National City to help them though Maggie said she didn't see him while she was out there. She then saw that J'onn was still out from the device that Rhea had used. They were then visited by Lillian Luthor and the real Hank Henshaw. She took a moment to tell them that her predictions had come true and she wanted to save her daughter from Rhea. They offered an alliance to stop the Daxamites but Kara and the others refused to work with her.

Winn then picked up a signal from Air Force One that signaled that President Marsdin was on her way to National City. She, Alex and Winn then watched as she and Rhea heatedly negotiated with one another as well as threatened. Kara was then surprised to see that Cat Grant was with the President. When they picked up activity from Rhea's ship, Kara flew off to the plane just moments after Rhea had attacked it. She managed to catch Ms. Grant as she was thrust out though they believed that President Marsdin was lost. The two of them became shocked when they saw her rise from the rubble, in an alien form. She took them back to the Alien Bar where Kara learned how Cat had ended up with the President and who Marsdin really was. Marsdin informed them that there was a special cannon at the D.E.O. that could be used to bypass the shields on Rhea's ship and destroy it. Kara told her that they couldn't as Rhea had both Mon-El and Lena with her but the Marsdin told her that it was an order. Kara went off to think about what to do, whether to obey the President or save her friend and boyfriend. She ran into Ms. Grant and told her about her trouble. Cat told her that having loved ones is everything and it wasn't wrong to want to fight to keep her loved ones safe as it gave them all a strong reason to fight. Kara thanked her for the advice and flew off to agree to the alliance with Lillian and Henshaw.

Lillian's plan was to use a portal that was stored in the Fortress of Solitude to sneak onboard the ship and rescue their loved ones before leaving and allowing Alex and Maggie to use the D.E.O.'s positron cannon to destroy her ship. The two of them and Henshaw managed to get onboard and Kara was able to take out any Daxamite guards they ran into. As they looked through the ship, they bumped into both Mon-El and Lena who had escaped and were trying to leave themselves. Kara quickly ran to Mon-El but recovered herself as Lena knew that Mon-El was dating Kara Danvers, not Supergirl and told him that Kara sent her to get him for her benefit. They then went off to the exit point but only Lillian, Lena and Henshaw had been teleported out of the ship. Kara however had anticipated that Lillian might double cross them so she had Winn place an override chip on Henshaw to take control of him and make him reopen the portal for them. When it did, Kara told Mon-El that she wasn't going as she had to try and reason with Rhea to stop though he tried to tell her that his mother wouldn't listen. Kara told him to leave and they shared one last embrace before she watched him head back. Kara then went to the throne room and confronted Rhea, telling her that it was now over. However, Rhea wasn't moved or worried as the cannon had been destroyed and she told her she wouldn't sway her to stop. She then revealed that it was she that killed her husband and Mon-El's father so her words were meaningless to her. Kara was then surprised by a sneak attack and looked up to see that it was her cousin.

Kara was surprised that Clark would attack her but Rhea explained that he doesn't know its her. Her cousin had come earlier to stop Rhea and she had poisoned him with Silver Kryptonite. Now he can only see her as General Zod and hear her pleas to him as his threats to conquer Earth once and for all. Kara and Clark started to battle as she kept trying to find a way to reach him. Their fighting spilled into the streets of National City. Kara was finally able to beat and subdue Clark but the strain of the battle caused her to collapse. They were found by Alex and she took them to the Fortress of Solitude to recuperate. When the Kryptonite was out of Clark's system, he had apologized to Kara but was also awed with the fact that she had defeated him. Kara tried to brush it off as him not being in top form from the Silver Kryptonite but Clark insisted that it didn't weaken his strength at all and he had been fighting as hard as he could. They then went to try to find something in the fortress' archives about the old wars against Daxam and they found a tradition that they felt would give them a chance to stop the invasion.

They all returned to the D.E.O. to find that they had managed to reclaim it from the Daxamites. Kara introduced her cousin to Mon-El and they learned that J'onn was still unconscious. They then shared what they found in the fortress, the Daxamite right of Dakkum Or but Mon-El quickly said it was a bad idea. When they saw that Rhea was launching another attack, Kara quickly contacted Rhea and issued Dakkum Or, a trial by combat. Should Kara defeat Rhea then she and her army must leave Earth. However, should Rhea beat Kara then she and her invasion will be allowed to commence without their interference. Mon-El tried to talk her out of it, even arguing that her cousin fight in her place against Rhea, but Clark stepped in and told Mon-El that Kara had beaten him which makes her the champion for Earth. She then asked for Clark to help her train for the fight. As they trained, Kara wondered if she really was able to defeat Rhea and Clark argued that she could. Kara then confided that she was scared as she now had everything she could ever want, great friends, a great job and a great boyfriend and she was scared of losing it all. Clark told her that those things were the reason that she would win because she had earned them all and wouldn't allow for any of them to be taken away. Kara and Clark then went to see Cat Grant in getting her help to keep bystanders away from Rhea's fight with Supergirl so as not to have anyone get hurt. Ms. Grant also asked if the two of them would help her talk with James as she had learned that he was Guardian and wanted to talk him out of it before he got himself hurt.

The two of them were then contacted by Lena and Lillian Luthor and asked to come to L-Corp. They arrived to find that the two of them had a device that Lex had been working on. It had been designed originally to disperse a trace quantity of Kryptonite into the atmosphere with the purpose of making the Earth uninhabitable for Kryptonians. Lena had taken and modified it to disperse lead instead so as to make the planet uninhabitable for the Daxamites. However, if it was used then it would expel all Daxamites from the planet, including Mon-El. The two of them returned to the D.E.O. with news of the device and Mon-El told them that if they had to use it, then they will. Kara argued that they wouldn't need to use it if she beat Rhea. Mon-El told Kara that he would go with her when she faced his mother.

They arrived at the rooftop where they agreed to have the battle and Rhea arrived with her guard. The two of them began their battle but Rhea quickly called for her army to begin attacking the city, violating the rules. Kara told Mon-El to go and protect the city while she stayed to deal with Rhea. Rhea goaded Kara into attacking her which Kara did and it revealed that Rhea had laced her insides with Kryptonite. Kara was weakened and beaten down by Rhea until Mon-El arrived with the switch for Lena's atmosphere device. Kara gave one last look at Mon-El before she activated it, dispersing lead into Earth's atmosphere. The Daxamite army quickly fled along with every Daxamite ship, stranding both Rhea and Mon-El. Rhea quickly succumbed to it and Mon-El left his mother to her fate as Kara had told him about how she had murdered her father. Mon-El was starting to suffer under the effects of the lead as well and Kara quickly brought him to his space pod. Kara then tearfully gave Mon-El her mother's necklace for him to remember her by before she told him that she loved him. Mon-El told her that she was the reason why he was now a better person and they shared one final kiss before he entered the pod as his condition worsened. Once in the pod, he gave her one last look before Kara watched him leave the Earth.

Kara was off on the terrace of the D.E.O. where she was joined by Clark who told her that he was going to head back to Metropolis. He told Kara that he was humbled by her selflessness as he didn't think he would be able to do the same had he been in her position. He told her that she was stronger than he could ever hope to be. Later, at Catco, she went to see Ms. Grant and confided that for the first time, she had everything she could've wanted but now she lost the one she loved. Ms. Grant told her to not give up on herself just as Kara heard that there was an emergency. She then made an excuse to leave though didn't hear Ms. Grant call her Supergirl. Kara headed for the emergency but let herself send her heart out to Mon-El.

Personality
Kara is kind, caring, selfless, intelligent, brave, and has a sense of justice, honor and good morals, however, when she makes mistakes, she feels guilt and remorse for her actions. Nevertheless, she has a bit of a nagging side, trying to show that she knows what's best for everybody and providing criticism to all who surround her, leading to some backlash with people like Alex Danvers and Mon-El.
 * -|As a civilian=

Due to her being a new superhero, Kara unfortunately does not have the confidence that her cousin Clark Kent possesses. She is also sometimes short-tempered and sometimes lets her emotions get the better of her. But after being a hero for a year she gained more confidence in herself and her abilities and get a better grip on her emotions out on the field.
 * -|As Supergirl=

Kara is also very forgiving and willing to give people several chances hoping to help her aunt Astra find redemption, though ultimately didn't' get the chance because Alex killed her. However, despite her adopted sister killing her aunt Kara chose to forgive her. She is also willing to look past Lena Luthor's ties to the Luthor family seeing her as her own person, whereas many are unwilling to look past her relation to Lex Luthor.

Despite her living on earth for sometime she has a great understanding of other races and their culture in the universe.

Despite loving her parents as a child, since becoming Supergirl, Kara has learned much more about the people they really were and has become quite disgusted and enraged with them. She learned that Alura used her as a means to arrest Astra for her crimes which ironically were an attempt to save Krypton, as Alura was one of the many who refused to accept its impending fate, this made Kara especially resentful towards her mother, though she soon considered that her mother believed that the alternative of using Myriad to control the populace was unethical and an action not worth taking, but not to the point of defending her mother's unspeakable actions, she also learned that father, Zor-El developed the Medusa Virus as a means to kill all lifeforms other than Kryptonian, as a means to defend Krypton from invasion; the more she learns about her parents' true natures, the more Kara feels ashamed of being their daughter.

Kara has a good and loving relationship with her adopted parents; Jeremiah and Eliza Danvers, although she addressed them by their first names instead of as "dad" and "mom". She was devastated when her adopted father had apparently died and was happy to later discover that he was alive. Despite her affection, she had no blind spot for her adopted father, because her biological parents had betrayed her in the past.

Kara has also shown unwavering loyalty in her friends. For example, when everyone else thought Lena broke her step-mother out of prison she refused to believe that she was guilty, also when most members the Legends, Team Arrow, and Cisco Ramon didn't trust Barry after he altered the timeline Kara, Oliver Queen, Jefferson Jackson and Martin Stein still trusted him, mainly because these said teams members and Cisco were all being hypocritical; as Kara would have done exactly the same thing Barry did, if she was in an emotional state, and not thinking clearly. Kara also cares deeply about her friends and family and will do everything she can to help them, or cheer them up when they are sad, and save them even if it risks her own life to do so.

Kara also has shown that she is willing to die for her adopted home world but also shown that she will do what needs to be done to save it. Weather it's sacrificing her own life to do so and also giving up her own happiness our even regrettable kill someone to do so. For example she gave parasite one more chance to stand down and give up but parasite was too far gone and seeing how dangerous and not having the means to contain him she had to overload him with so much energy that it destroyed him. When Rhea broke her promise and started to destroy national city and kill humans and threatened to annihilate the rest of the planet, with Mon-El blessing she turned on Lex's device filling earth atmosphere with lead now making it impossible for all Daximites to be on earth. This killed Rhea and sense Mon-El had absorbed yellow sun radiation he was able to withstand it for some time so Kara brought him back to his pod and they said their goodbyes to each other and she gave him her mother's necklace so that he wouldn't be alone wherever he goes.

Powers

 * Kryptonian physiology: Normally, like all Kryptonians, Kara's capabilities are no greater than a normal human of her physical conditioning. However, once charged by the energy of a blue or yellow sun and metabolized into her body, she becomes able to perform various inhuman feats. While generic for her race, having grown up half her life with these powers have allowed her to use these abilities with far greater control and an equally greater level of raw power compared to other Kryptonians. When Superman was under the effects of Silver Kryptonite he fought her without restraint and yet she was able to best him in their fight, using his rage to outfight him; however, it should be noted that Clark and Kara were at the brink of exhaustion at the time.
 * Solar energy absorption: While Kara's powers are dependent on the energy spectrum from a blue or yellow sun, her body is able to constantly and passively absorb such energy while exposed to it, essentially keeping her reserves fully charged near-constantly. Direct exposure to sunlight will also accelerate her recovery from any injuries she does manage to sustain.
 * Accelerated healing factor: Kara's solar charged metabolism accelerates her healing and allows her to burn calories at a fast rate, making her resilient to weight gain. Upon being struck by an alien war hammer which penetrated the skin of her arm, when the piece was removed she healed instantly.
 * Contaminant immunity: Kara has an immunity to all forms of disease and contaminants on Earth. However, despite being unable to being inebriated or intoxicated by drugs or alcohol from Earth, she has shown herself to have a particularly low tolerance to alien alcohol.
 * Flight: Kara is able to manipulate her own gravitational field to generate thrust and propel herself through the air, often at supersonic speeds, much faster than she can travel by foot. As such, she is able to levitate and fly past Earth's atmosphere and near the planet's orbit. James once described her as being even faster than Clark.
 * Heat vision: By concentrating every solar energy reserve she has in her body, Kara can emit blue energy beams of variable intensity from her eyes. Due to her control over the beams, she has demonstrated being capable of burning through stone and welding metal, causing small explosions and fires, and physically repelling enemies with similar durability, making it useful in combat. However, she has personally utilized it for more mundane uses, such as heating up beverages and cooking food.
 * Invulnerability: Kara is essentially invulnerable to all Earthly weapons, with bullets simply ricocheting whenever they come into contact with her skin. However, her durability has proven to be somewhat weaker than that of her cousin, Clark Kent. This is probably due to the fact that he has spent more time under the Earth's yellow sun than Kara has. She is immune to most forms of extreme punishment, as shown when she was completely unaffected by attacks with the A.T.O.M. Exosuit, and Mick Rory's Heat Gun. She also was able withstand the Flash's lightning despite it having knocked out both Firestorm and Atom though this might be because it was not all directed at her. Caitlin Snow even stated that Kara was "invincible" while she was mind controlled into fighting Barry. However, her near immunity to damage and outside forces did not protect her from the Dominator's mind control device, which forced her to mindlessly turn against her allies.
 * Extreme heat resistance: Kara feels no pain when exposed to extreme heat, as shown when her shirt caught fire after The Flash caught her as she fell out a window and (accidentally) sped her out of National City, and she was able to extinguish the embers on her shirt by casually patting them. This was also shown when she removed a hot pan from her oven with her bare hands.
 * Longevity: As a Kryptonian, Kara's life span is considerably longer than a normal human and likewise ages much slower.
 * Super breath: Kara is able to exhale powerful gusts of air from her mouth which are similar to force winds. She can also cause the temperature of her breath to drop, therefore able to freeze nearly anything.
 * Super hearing: Kara has super-sensitive ears that can perfectly pick up sounds from miles away and even through structures.
 * Super speed: Kara possesses the ability to move at incredible speeds, far greater than that of any normal human. Once she started to actually use her powers in a less restrained way, she was easily able to move at greater supersonic speeds, even to the point where she could almost catch up with a tachyon enhanced speedster like Barry Allen, though it is worth noting that, at that time, Barry could easily go faster than Mach 13 whereas Kara's top speed peaks at around Mach 6-7. She commonly uses her speed to appear and disappear faster than people can notice, as well as to somehow change in or out of her Supergirl suit in seconds.
 * Super strength: Kara's strength is enhanced under a yellow sun, enough to easily kill a normal human if she were to attack them directly. After embracing her powers as Supergirl, Kara's true potential started to manifest, allowing her to stop a train moving at Mach 1, or lift over a million tons of condensed star material. While not limitless, the extent of her super strength is undetermined; making her among the strongest terrestrial beings in the known multiverse alongside her cousin and J'onn J'onzz. Despite her strength, Kara still must physically exert herself when fighting other super powered beings of similar levels of strength and durability, such as other empowered Kryptonians, as well as to lift or press objects or structures that are larger than herself, such as planes or ships.
 * Super leaping: Kara is able to jump several stories in a single bound without having to fly. Even as a child, she was able to leap onto a crashed car several feet away, and when trying to fly again after several years, she was at first only able to jump upwards two stories before shooting skyward. While fighting Alex Danvers, who was controlled by Myriad and wearing a Kryptonite-exosuit, both she and Alex jumped several stories into the air while attacking each other.
 * Telepathy immunity: Kara is immune to all forms of telepathy; even from someone as powerful as J'onn J'onzz, but not from the Dominator device.
 * X-ray vision: Kara has the ability to see through objects, except for lead.
 * Oxygen independence: While Kryptonians do require oxygen, their physicality allows them to survive while inhaling more harsh forms of it.

Abilities

 * Genius level-intellect/Eidetic memory/Skilled detective: Kara has been shown to be quite intelligent due to growing up in a advanced civilization as well as having knowledge about other alien species and their abilities and their heritage. Early in her time on Earth she teased Alex about calculus being an advanced placement subject on Earth since children on Krypton did calculus from age 4. She found high school sciences on Earth easy as well. Kara also seams to have an eidet memory because she can recall everyone she’s ever saved when she was investigating a cult. Kara also has to carefully calculate how she uses her powers so she doesn’t kill someone or destroy the city or catch someone or a building, vehicle, ship with out braking it. Also due to her reporting she picked up investigating skills and, while not at Maggie's level, she did deduce Jack's password on his encrypted computer and follows up on her stories' leads.
 * Dancing: Like Barry, Kara is a talented tap and ballroom dancer as shown in the Music Meister's dream world.
 * Expert hand-to-hand combatant: Since joining the D.E.O., Kara's sister Alex has been teaching Kara to better handle herself in battle against opponents with formidable powers of their own, including how to use their own momentum against them. Ultimately, even with her powers temporarily disabled, Kara has become a highly proficient fighter, able to compete against the more experienced Alex and Astra. As the series went, Kara became even better at this, managing to hold her own against Indigo in their fight, also defeating Maxima. Her proficiency in combining combat skills with her raw might became great enough to even defeat her physically stronger cousin Superman in one-on-one combat (however, it should be noted that Clark and Kara were at the brink of exhaustion at the time) and even fight on par with Rhea while weakened by Green Kryptonite.
 * Indomitable will: Even when weakened by Green Kryptonite, Kara was able to resist and keep fighting Rhea.
 * Bilingual: Kara is capable of fluently speaking English and Kryptonese.
 * Singing: Kara is noted by her sister to be a very talented singer. To which, in Music Meister's dream world, she was able to effectively be a lounge singer. Her voice impressed Barry to which he called her a good singer.
 * Leadership: Kara can inspire the people to be best that they can be and sometimes inspire criminals to do the right thing without resorting to violence.

Weaknesses

 * Kryptonite: Like all Kryptonians, even while empowered, Kara is vulnerable to the exposure of Kryptonite, a radioactive mineral from her home planet Krypton. Depending on the nature of the said Kryptonite, it will cause a different adverse affect on her;
 * Green Kryptonite: Green Kryptonite not only physically hurts Kara and weakens her physical attributes, leaving her vulnerable to weapons and anything in general that can kill a normal human, but if she is exposed to it for too long, it will kill her.
 * Red Kryptonite: If exposed to Red Kryptonite, it gradually destroys Kara's inhibitions and turns her into a corrupt version of herself. Left without morality, compassion, rationality, or any cares whatsoever, Kara will become malevolent and prone to hostility and aggression, making her a danger to everyone around her.
 * Silver Kryptonite: If exposed to Silver Kryptonite, it will cause Kara to go in a deep and frightful hallucination where nothing from the outside world can stir her out of it until it leaves her system.
 * Extreme energy: Extreme amounts of energy, such as the energy from the Reactron suit or Livewire's electricity, while she is at her peak, can be enough to kill Kara.
 * Electricity: Despite her invulnerability, Supergirl seems relatively vulnerable to large amounts of electricity. This was seen when fighting against Livewire, as she was hit with a rather large blast while mid-air and it nearly knocked her unconscious. She seems to have developed her powers since then, as she was able to withstand a powerful blast of the Flash's lightning with little to no effect. Though this may have had something to do with Flash's electricity possibly not being as powerful as Livewire's.
 * Red sun energy: Like all Kryptonians, exposure to the Red Sun will make Kara the equivalent of a human being on Earth.
 * Solar energy depletion: Using her powers to its maximum for an extended period can significantly drain her solar energy to the point where Kara loses all of her powers and is rendered more human-like for at least a day or more. This renders her as weak as a human, allowing Kara to get injured and killed as easily as normal humans. When she wasted away a very large amount of her solar energy on Red Tornado, she became mortal for a while until her body's solar energy reserves were recharged.
 * Dominators' orb: Kara has immunity to telepathy, however the Dominators' orb was capable of overriding this barrier and brainwashed her to battle her trusted friend and ally the Flash.
 * Lead: Kara can not see through lead, even with her X-ray vision.
 * Magic: Like all Kryptonians and humans, Kara can be affected by supernatural forces or powers. This is because her powers are due to her natural physiology and not from the supernatural.
 * High-frequencies: Though considered a strength, Kara's hearing does have its disadvantages. Since her hearing is more sensitive than a normal human's, higher pitch noises (sonic screams, etc.) can disorient her and cause pain in her ears, leaving her vulnerable in a fight. Therefore, enemies with sound based powers, like Silver Banshee can potentially be powerful enough to cause her ears to bleed.
 * Sound-dampening technology: The D.E.O. designed frequencies to block super-hearing and cause Kara slight pain when trying to use it in areas protected by the technology.
 * Phasing: Kara has no defense against phasing once shown in a battle against the Flash and in a battle with Martian Manhunter.
 * Hypnosis: Kara is vulnerable to hypnosis. The Music Meister put her in a hypnotic dream just by gazing at her.
 * Oxygen deprivation: Kara requires a regular influx of oxygen into her system in order to function. As such, she cannot breathe underwater or survive in space for long.

Equipment

 * Supergirl suit: Kara wears a protective suit as her super-heroine alter-ego, Supergirl, to hide her identity from her enemies, when she goes out fighting crime. It was designed by her friend Winn Schott and, though it is also unknown what materials it is made from, it is shown to be just as immune to damage as a Kryptonian, having only been pierced by alien technology, such as Vartox's axe, and by Kryptonite. Kara notably is able to change into her suit in seconds with her speed, usually keeping it underneath her civilian clothing.
 * Lead-based glasses: As a teenager Kara was given a pair of lead lined glasses to help her control her visual powers.
 * Interdimensional extrapolator: Given to her as a present by Cisco, it can create small breaches to allow travel between Earth One and Earth Thirty-Eight anytime she wants to. It also has communication functionality that can allow contact between universes.

Behind the scenes

 * In a nod to Brandon Routh's previous role as the title character in the 2006 film Superman Returns, Ray Palmer made a brief remark about Kara resembling his cousin.
 * Kara Zor-El debuted in Action Comics #252 (May, 1959) as the cousin of Superman, rocketed from Argo City before it's destruction. She later died in the Crisis on Infinite Earths (October, 1985) event. Kara was later re-introduced into the DC continuity in Superman/Batman #8 (2004). She was created by Otto Binder and Al Plastino.
 * The event of Supergirl losing her powers was called a "Solar Flare" by Jimmy Olsen, as he stated Kara's cousin, Superman also called it this at times when he depleted his powers. In Superman #38, part of The New 52, it is revealed that Superman's heat vision is a precursor to a power also called a "Super Flare", in which Superman release a large explosive force of his solar energy from his entire body, which leaves him depleted and the equivalent of a human for 24 hours.
 * In the comics, Supergirl has used several aliases for her civilian identity including: Kara Kent, Linda Lang, Claire Connors and most famously Linda Lee Danvers, who was later adapted to be a separate character altogether. Supergirl's name on the show, "Kara Danvers", is a combination of some of those aliases, this being the first instance this particular name has been used, though it was later incorporated into the comics.
 * Supergirl marks Kara Zor-El's third live action appearance; previously appearing in the 1984 Supergirl film (where she was portrayed by Helen Slater), and Smallville (portrayed by Laura Vandervoort). Both actresses who played Supergirl previously have appeared in this show.
 * Kara's skill in singing is a nod to her actor, Melissa Benoist's role as Marley Rose in the musically-centered series, Glee.
