Biography

Early life

Alexandra Danvers was born in 1989 in Midvale to her parents; scientists Jeremiah and Eliza Danvers.[3] When she was eight years old, Alex met and became best friends with Josie.[4] Since early childhood, Alex displayed a gifted intellect and brilliant attitude towards science. As a teenager, she enrolled in Midvale Junior High, obtaining remarkable results.[5] The star of her family, when Kara arrived in 2003, Alex was jealous due to her abilities and dismayed at the fact that Kara easily excelled at math and science.[4] Thus, she was secretly happy when Kara decided not to use her powers.[3]
Young Alex and Kara

The Danvers sisters in Jr. High school.

At first resentful of that "strange girl" who came into her life and constantly followed her around at school and embarrassed her in front of her friends,[6] Alex began to warm up to Kara and acted as her big sister, often comforting her when she was afraid or sad.[3]

One night, Kara took Alex flying, and the D.E.O. subsequently found out about Kara. They forced Alex's father to work for them in exchange for not taking Kara away. One year later, Jeremiah "died" protecting a martian from the D.E.O.'s ruthless director Hank Henshaw,[7][5] but Eliza told Alex and Kara that he was killed in a plane crash.[1]

Troubled teen

In high school, Alex's relationship with Kara became frosty as she blamed the latter for her father's death and resented having to be her "earthly ambassador". Alex completely put her focus into her studies and social life, becoming a popular girl alongside Josie. In high school, Alex met and befriended Vicki Donahue and secretly, Kenny Li, who was tutoring her in calculus. However, Alex never acknowledged him as a friend outside their tutoring sessions, which she would grow to regret.

When Kenny was murdered, Alex and Kara worked together to investigate his death, in which they discovered that Josie was having an affair with their history teacher, Mr. Bernard, and Kenny found out about it. Despite Josie's protests, Alex reported this to the authorities. When she and Kara were walking home, they were almost killed by a speeding car, whom they thought was Mr. Bernard. However, when Alex discovered that Josie was with him at the time of the attack, she realized he wasn't the culprit. She spoke to the Sheriff, who turned out to be the real killer and he held her at gunpoint, Alex though, showed no fear as she knew that Kara was coming for her. She was proved correct when Kara arrived and knocked out the sheriff, saving her life and making the pair's relationship whole. Afterwards, Alex's friendship with Josie fell apart and she was kicked out of the popular clique, but ultimately didn't mind much. Kara revealed to Alex that Kenny had a picture of her flying, but kept it a secret.[4]

Despite Alex's fallout with Josie and the popular clique, her friendship with Vicki persisted for some time. Alex loved sleeping over at Vicki's house, in which they would share her bed. However, when Alex started to develop feelings toward her friend, she felt confused and scared. Alex began to fight with Vicki over almost everything, even if it was stupid or insignificant, until they just drifted apart. This memory made her feel so bad that she buried it inside of herself for years, consequently not coming out as a lesbian until much later in life.[8]

Over the years, the bond between Alex and Kara became so strong that neither of them can imagine their lives without the other.[6]

After graduation, Alex pursued an MD/PhD at National City University.[5] While there, she had a boyfriend, Capraro, who would write poems about him and Alex fighting and they allegedly broke up because of it.[9] Alex also conducted research in genetic engineering at Stanford, which caught the D.E.O.'s eye.[1]
Alex meets "Hank Henshaw"

Alex first meets "Hank" after she is arrested.

Despite her intelligence and academic results, Alex grew up a troubled young adult who used hard-partying and heavy drinking to cope with her insecurities and troubles, including her latent homosexuality and the loss of her father. This escalated to the point where she began falling behind in school and was placed on academic probation. In 2012, after a night of drinking and clubbing led to a DUI and her arrest, "Hank Henshaw" visited Alex in jail and offered her a position at the D.E.O., telling her that she was special just like Kara and owed it to her father to be the person he knew she could be.[5]

Working for the D.E.O.

Alex had to go through a full year of training before being allowed to work in the field.[10] Despite her close connection to Kara being one of the main reasons the D.E.O. hired her, Alex soon proved herself as one of the best agents, quickly becoming "Hank"'s second-in-command.[3] Alex struggled with dating and romance and unconsciously suppressed any feelings she developed towards other women.[8]

In 2015, Alex had to attend a conference in Geneva but the flight 237, on which she was traveling, was sabotaged by Vartox in an attempt to kill her and other D.E.O. agents onboard. Though the plane was saved by Kara from crashing, Alex later berated her sister for doing so, angry that she had revealed herself to the world, and now there is no turning back. Kara was later captured by the D.E.O. and taken back to their base, where Alex revealed her identity as a D.E.O. agent. After Kara was defeated and almost killed by Vartox, Alex rescued her. revealing that the only way that the Fort Rozz escapees could get back at Kara's mother was through her now. She later went to Kara's apartment, apologetically explaining herself, and encouraging Kara to be a hero. The two then went to the D.E.O. base, where they convinced Director "Hank Henshaw" to let Kara defeat Vartox.[3]

A week later, Alex along with the rest of the D.E.O., tested the limits of Kara's abilities, firing missiles into the sky at her. Afterward, Alex debated with Kara over the necessity of the tests before Kara had to leave to stop a fire raging at National City Port. Days later, the D.E.O. investigated the theft and murder of a security guard on Plastino Chemicals factory, with Alex calling Supergirl to assist in the investigation. Later at the D.E.O. base in the training room, Alex defeated Kara in a sparring match with the assistance of Kryptonite emitters in the room, in an attempt to prepare Kara for anything she might face. She later came to Kara's apartment and questioned her sister as to whether telling James and Winn her secret identity was a good idea, soon after apologizing to Kara, regretting how she handled things earlier however, Alex was soon called by the D.E.O. who needed her back at the base, telling Kara that she'd call her.

The Hellgrammite abducted Alex and takes her to General Astra, who revealed her true identity after she mistaking her for Alura. Alex was later found by Kara who had tracked her down with her super hearing. A fight between Kara and Astra ensued, and Hellgrammite attacked Alex, who tried for radio contact D.E.O., who was able to overcome him by forcing the stinger he protruded from his hand into his heart. Later at the D.E.O. base, Alex was asked by Kara to train her, with Alex promising to make Kara better than herself. Alex then showed Kara a room that had been setup containing an Artificial Intelligence program of Alura that had been sent with her pod. Leaving Kara to talk to it, she thanked "Henshaw" for helping her set up the room.[10]

Alex attempted to continue the relationship, but upon seeing the relationship between Samantha and Ruby Arias, she confessed to Kara, her desire to have children. Maggie, soon realized what was happening and told Alex, that she has to say it, in which Alex ended the relationship with Maggie. The two spent one more night together and the pair parted ways amicably, with Maggie telling Alex that she was going to be a great mom. The heartbreak that Alex suffered caused Kara to take her back to Midvale, in which the two ended up having an argument. The next day, the pair made up, and returned to National City, in which they found a ship which contained Mon-El.

Crisis on Earth-X

After having dealt with a Dominator, Alex and Kara talked about Mon-El in which Alex discovered a wedding invitation to Barry Allen and Iris West's wedding, though hesitant at first, Kara decided to go with Alex. Alex went to the rehearsal dinner, in which she started drinking and was soon joined by Sara Lance. Alex mentioned to Sara her sexuality and how she had to cancel her wedding, and the two continued to drink before making out outside Jitters. The two ended up at a hotel room in which the pair had sex, three times. Alex wakes up to discover Sara next to her and sneaks out. Alex arrived to the wedding where she and Kara talked until Sara arrived who asked if Alex was okay after falling out of bed, thus revealing their interaction to Kara. Kara told Alex that it was okay and mentioned how Sara was an assassin, Alex calls her a "sassy assassin". Alex and Kara entered the church and watched the wedding, but before the ceremony could continue, the priest was killed by Overgirl and the invading Nazi forces of Earth-X. Alex and Sara teamed up and took down many Nazi's as well as knocking out Prometheus.

Everybody returned to S.T.A.R. Labs in which they discovered that the Nazi's were from Earth-X. Alex runs into Sara and was nervous, though Sara didn't think too much of it. Alex then speaks with Kara and admitted that she doesn't know what to feel due to her sleeping with Sara and wondered if she made the right choice when it came to Maggie. Kara tries to console her but Alex believed that she made a mistake when it came to sleeping with Sara and breaking up with Maggie. When the team had discovered Overgirl's location, Alex and Sara teamed up again in which Sara asked if that was okay, Alex agreed. Alex battled along with the others and seemed to be winning until the arrival of Metallo who quickly took down Supergirl and Firestorm with ease, and Alex and the others were knocked out. Once they awoke, they were imprisoned and discovered that Overgirl was dying and that they planned to cut out Kara's heart and put it into Overgirl's. Metallo then knocked them all out again in which they were all taken to Earth-X except Kara.

After awaking on Earth-X, Alex and the group met Ray Terrill who revealed he was in prison because he loved the wrong person, this worried both Alex and Sara due to their sexuality. Suddenly they met the Earth-X version of Sara's father, Quentin Lance who planned to have them executed along with Ray. When they tried to escape they were shocked by the collars they were wearing and were almost executed until the arrival of Leo Snart. Leo freed them and helped them escape when he freed Ray which allowed him to use his powers. They escaped to the Freedom Fighters, who were led by the Earth-X version of Winn Schott, and he refused to allow them to go to the breach as he planned to have it destroyed. Alex tried to convince him due to knowing his Earth Thirty-Eight counterpart, but he still refused. Alex attempted to find a gun so that she could try to rescue Kara, but Sara stopped her by mentioning that she is part of her team now. Sara learned about Maggie and talked to Alex about her own Maggie, Nyssa. Sara then told Alex that she should follow her instincts and that her reasons behind the break-up were valid. Eventually Winn was convinced by Ray and Leo to attempt to get to the portal, in which Alex and Sara teamed up against the Nazi's. They succeed in taking the site, but during the conflict Martin Stein got injured.

Alex along with the other heroes

Alex and the rest of the team along with Ray and Leo arrive back on Earth One, where with the help of the Legends, Team Flash and Team Arrow were able to rescue Kara and escape to the Waverider. Alex was reunited with Kara, in which Kara joked about how their plan to come to Earth One went up in smokes. They soon discovered that Martin Stein dies from his injuries. In the final battle with the Nazi's, Alex and Sara teamed up against the Nazi's and won after the deaths of Black Arrow and Overgirl. Alex attended the funeral of Martin Stein along with everyone else. Alex and Sara had one last conversation in which Alex agreed with Sara that she should follow her instincts, they hugged before parting ways. Alex and Kara said goodbye to Barry, Iris, Oliver and Felicity and returned to Earth Thirty-Eight.

The rise of Reign

After returning home, Alex along with Kara, Winn and J'onn listened to Mon-El and Imra's interpretation of their future, Imra revealed to them that they are part of a group called The Legion and that Mon-El helped create them through what he learned from Supergirl. Alex went to Kara's Christmas party, where she bonded with Ruby Arias through tales of her adventures with Supergirl, who Ruby idolizes. Later when an unknown Kryptonian arrives in National City leaving marks all over the city, Alex finds out along with everyone else that the Kryptonian is said to be the Krypton equivalent of the devil, Reign. When Reign finally makes her presence known and is called out by Kara, Alex tells Kara that she needs to embrace her Kryptonian side. Kara did, but was brutally beaten to unconsciousness. Alex arrived at the scene and took Kara back to the D.E.O. where she attempted to keep Kara alive after her brutal fight with Reign.

Mon-El awakened Querl Dox from his hibernation in order to help Kara and Alex watched with the others. Mo-El and Imra told Alex and the others about their mission and that they know Reign eventually left but with Supergirl out of commission, Reign is creating terror. In order to capture her, Alex, J'onn and the DEO staged a robbery in which Reign arrived to kill them, but when they revealed themselves she hesitated, this allowed the DEO to use their advanced weapons to capture Reign, in which Alex placed a chain with kryptonite on hjer, but she resisted it and broke out and used a whip that was used on her to snap Alex's leg. Alex was taken care of by Querl, in which Alex decided to watch over Kara, she would use words of encouragement that Querl would use to help Kara awaken. Alex witnessed Kara awaken and told her of the plan that the Legion were doing, in order to subdue Reign. Kara left and was successful in subduing Reign, though she escaped.

Bonding with Ruby

With her leg broken, Alex was side-lined from active duty, when Sam couldn't get her usual sitter for Ruby, Alex offered to look after Ruby. Alex and Ruby bonded throughout the day, in which Alex got a text from Maggie, asking about her passport that she left at her place, Alex pointed out to Ruby where she believed it to be and she was right. Ruby then admits to Alex that she is being cyber-bullied, refusing to allow this, Alex had Ruby take her to the girl and pretended to be an FBI agent, and scolded the girl for cyber bulling. Alex and Ruby spent the rest of the day bonding, when Sam arrived to pick her up. Alex pretended that Ruby was a nightmare that Sam laughed about. When Alex asked about Sam's business trip, Sam had no knowledge of it, Sam then asked for Alex's help.

Fully healed from her leg injury, Alex ran some tests on Sam to find out what was wrong but had no luck in finding out. While at the DEO, Kara arrived with a dying Lena, who had ingested some poison, after asking Kara several questions, Alex deduced the poison and had Kara use her freeze breath to counteract the poison. Alex and Sam then went to Kara and Lena in which Sam revealed to them about her blackouts, after hearing from a friend, Alex informed Sam, Lena and Kara that there was nothing wrong with her blood.

Director of D.E.O

Personality

Alex is a courageous and independent person, who faces danger head on. She is caring, confident, and headstrong, with the same passion for bio-engineering like her parents. Alex had dedicated her life to protecting her sister, Kara, and rarely found time for herself since teenhood.

Despite her good traits, sometimes Alex can be impulsive and prone to make difficult decisions crossing the line between right and wrong (some might even classify her as morally grey); such as when she stabbed Astra in the back, or when she assaulted a Cadmus facility on her own by placing mines in the structure to blackmail Lillian Luthor, even if on those occasions it was to save first J'onn J'onzz's and then her father's life.

However, she has a great sense of justice, since when J'onn took the blame for Astra's death, as he did want not Alex to lose her relationship with her adopted sister, knowing it was wrong, she eventually confessed to Kara her role in Astra's death despite her fear to lose her.

After much soul searching and exploration, Alex finds the courage to come out as a lesbian to herself, then to her ex-girlfriend Maggie Sawyer, then Kara, her mother Eliza, her friends and her father Jeremiah. Alex's interactions with Maggie show a more flustered, awkward and almost goofy side of her personality, similar to that of Kara.

Above all, Alex is a strong woman. She fights for what she believes in and has a difficult time giving up. When she was kidnapped by her childhood friend, Rick Malverne, she never stopped trying to escape and was able to use her D.E.O. training to help her survive. She has been referenced as being a "bad-ass" by many people.

After losing Maggie, Alex became devastated unable to cope with it and started drinking heavily. She is also fond of leather jackets.

    • Expert physician: Alex has performed medical procedures on humans and aliens, such as patching James Olsen up after he was knocked out by a super soldier with Livewire's abilities,[28] examining a comatose M'gann after she suffered a psychic attack and figuring out that a Martian mind meld with J'onn would be the only way to save her.[28]

Equipment

  • Kryptonite-powered exosuit: Alex used a special cybernetic exosuit powered via Kryptonite, which she got from Non while under Myriad's mind control, to allow her to fight superhumanly stronger opponents such as Kara Danvers or Metallo by physically enhancing her. Also, the suit's forearm was fitted with a Kryptonite-powered energy gun and it could generate green, concussive shockwaves to physically repel and incapacitate opponents, especially Kryptonians.[18][21]

The pistol itself is shown to be very powerful as it sends any target it hits over a distance and it has even proven strong enough to take down a White Martian, albeit weakened from J'onn and M'gann. Following the constant attacks by the Worldkillers, Winn has upgraded the gun to use not only laser bullets, but also Kryptonite bullets when fighting the Kryptonian witches.
