Mon-El

"Wherever I go I'm gonna be better because of you. You'll be in my heart. I promise I'm going to be the man that you thought I could be... I promise."

- Mon-El to Kara

Mon-El is the Prince of Daxam, who crash-landed on Earth after escaping the ravaging of his home planet. Mon-El is also the son of the late Lar Gand and the late Rhea, and the boyfriend of Kara Danvers. While adjusting to living on his new home world, he begin to use the identity of Mike Matthews. After he started to work alongside Supergirl, he became inspired to try and use his new powers to help protect the Earth and become a superhero as well.

Early life
Mon-El was born on the planet Daxam to his parents, king Lar Gand and queen Rhea. He was raised as a prince to his people and spent most of his life indulging himself in all the benefits of his privileged position, becoming knew by many as the "frat boy of the universe". In the fulfillment of his political duties, he went to many different planets; among these was Maaldoria, a world from which his family regularly bought and sold slaves, though he did not personally agree with this practice, and Warworld, where he oversaw a battle featuring the powerful gladiator Draaga, during which the aforementioned was injured by a sword to the right leg.

At some point Mon-El took a girl to the Bismuth Mountains on Sedenach, presumably for romantic reasons. He has also had encounters with fifth dimensional Imps, and grew to both dislike and distrust them, firmly believing the only way to deal with them is to kill them quickly.

Daxam's demise
The day Krypton was destroyed, the debris from the planet showered on to its sister world, Daxam, causing immense destruction and an immeasurable number of casualties. Mon-El was in his room with a girl when his guard barged into the room to tell him that he had to evacuate. He took a moment to look out the window to see the devastation before the guard pulled him away, telling him to leave the girl he had been with and to come with him. He rushed out of the palace to see that many of his people were hurt and dead around him but the guard told him to forget them as he had to get to safety. They made it to a Kryptonian pod from a visiting delegate who was trying to use it to leave the planet. Mon-El watched his guard angrily kill the delegate in cold blood in retribution for what Krypton had been doing to Daxam before the prince was put in the pod. He then activated it and made his escape from the planet.

Landing on Earth
The pod traveled past the Well of Stars, a region in space where time is ceased, and got stuck there for decades. This kept him from aging and he remained there in suspended animation until the pod broke free and then eventually found its way to the planet Earth where it crash-landed on the outskirts of National City.

Supergirl quickly discovered the pod, and she and J'onn J'onzz took the man to the D.E.O. to run some tests. However, they discovered that he had skin that could not be penetrated by a needle and so the man remained comatose. Because of the pod and his apparent vulnerability, both Supergirl and Superman believed him to be a fellow Kryptonian. In his coma, he began to drain some of the nearby energy to help regenerate himself as he was being exposed to Kryptonite.

Escape from the D.E.O.
He eventually came to and escaped into the city, and found his way to a satellite station in hopes of sending a signal to his planet. The signal was detected by Winn and Supergirl, and upon finding out he was from Daxam and fearing that he was behind the attack on President Marsdin she rushed to confront him. The two quickly brawled against one another until Supergirl managed to temporarily incapacitated him. He was thrown in a cell where he was confronted by Supergirl who he quickly realized was a Kryptonian due to the glyph she wore. They argued a little about their respective views on the other's people before she asked him why he had attacked the President but Mon-El had no idea what she was even talking about as he was only trying to send out a distress call. Supergirl didn't seem to believe him and he quickly gave up explaining himself as he knew that she wouldn't believe him because of him being a Daxamite while she was a Kryptonian. The next day, she apologized for her prejudice after realizing Mon-El wasn't behind the assault on the President. She told him that Daxam had become a wasteland, as a result of the planet's moon being struck by Krypton's debris that disrupted Daxam's gravitational force. He then realized his only option was to remain on Earth.

Adjustment to living on Earth
In the following days, Mon-El is placed under the D.E.O.'s custody while they begin processing him. Mon-El claimed that he was a guard to the Royal Family and had escaped when the prince gave him his place in the pod when Daxam was being destroyed. As he and Winn begin to gauge his powers, he is given a break where he stumbles upon Kara speaking with her mother in a hologram. He makes a suggestion of going out to check out the city but Kara insists that he needed to remain at the D.E.O. for safety though Mon-El wasn't sure why he he wasn't safe. Later, he managed to talk Winn into going out with him to a bar where they spent the night playing drinking games with the attendees. Mon-El then was challenged to an arm wrestling match where he accidentally broke the wrist of the man that he was playing against. Another guy then went to punch him but broke his hand on contact with Mon-El's face. Winn then quickly went to take Mon-El back. He then was confronted by Kara where he realized that the reason he had to stay at the D.E.O. was because it wasn't for his safety but for the safety of others. Kara speaks with him about her own beginnings on Earth as well as her parents and what they were. He then told Kara that he heard about what happened at the fight club and informed her all about Draaga's weak spot. Later she comes to him and, after she apologized for having treated him harshly in the days before, Kara 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.

Soon after, Kara asked Winn to make Mon-El a fake ID as "Mike Matthews", and arranged him a job as a CatCo intern. While Kara tried to coach him in human customs and work ethics, he resisted the boring lifestyle of a desk job, refusing to do any work and engaging in office sex with Eve Teschmacher. Eventually, he was fired from CatCo, then Kara, under Alex's advice, tells him that she will not force him to live as she sees fit and that he can find what he likes.

Mon-El found new work as a loan enforcer, to which Kara is oblivious. Eventually, however, she caught him attacking an alien for his employers. 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.

Path to heroism
Soon after, Kara was seriously injured after a battle with Parasite. After seeing her unconscious and still thinking about what was said during their conversation, he became overcome by guilt and left. Mon-El was found by Alex drinking alone at the underground alien bar. Alex appeared to belittle Mon-El and saying that she believed he was a coward but reminded him that Kara, who constantly put herself in danger and was hurt by Parasite, sincerely believed otherwise. Moved by this, Mon-El took off alone to battle Parasite, however, he was no match for the rampaging monster. In the midst of the destruction, however, Mon-El performed his first heroic deed by saving a by-standing child. With the help of Guardian and a recovered Supergirl, they managed to defeat the threat. Seeing Mon-El redeem himself, Kara thanked him, while also noting Guardian's contribution. That night, Mon-El wandered the streets looking for people to help. Approaching what appears to be a sick homeless man, he was instead subdued by the Cadmus agent in disguise. He was transported to a Cadmus facility, where Supergirl was baited to rescue him. After threatening to kill him with lead, Lillian Luthor succeeded in forcing Supergirl to overload her powers, despite his pleas for Kara not to do it. Cadmus then proceeded to obtain Supergirl's blood for the purpose of obtaining information on "Medusa". Left in the cell, 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.

Kara, Mon-El and friends celebrated their return in Kara's apartment. She told Mon-El he was brave throughout the ordeal. He replied any courage he had, he learned from her. During this time Mon-El began developing a romantic interest on Kara, asking Winn and James if she was "mated to anyone". James replies that Kara hasn't mated with someone yet.

A few days later, Mon-El is invited have the Thanksgiving dinner with Kara's family and friends. Later, that night, after a rough fight with Hank Henshaw outside the alien bar, Mon-El contracted the Medusa Virus, which was deadly to all alien species except for humans and Kryptonians. Mon-El was then quarantined at the D.E.O., where he soon collapsed from being infected by the virus. Kara went to visit him and apologized as it was her father who created the Medusa Virus. Mon-El told her that he didn't blame her or her father and then moved to share a kiss with her before he passed out. Eliza Danvers was able to extract a sample of the virus to create a cure. After he recovered, he told Kara that he had no memory of his time being sick so didn't remember kissing her. In the aftermath of the incident involving the virus, Mon-El became a bartender at the alien bar due to many aliens having been killed. When Kara came to bar to speak to Maggie about investigating the disappearance of Izzy Williams, Mon-El decided to help her. The two pretended to be a couple of millennials and visited a clinic linked to the disappearances that was offering money rewards for blood tests. 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 go get help, Mon-El did likewise and follow her. After realizing the new planet they landed on had a red sun, depriving them of their powers, the two were ambushed by a harmless hermit alien and Mon-El realized they were 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 afterward, 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 Mon-El had a talk with Kara 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, Mon-El and others, seeing her in agony, were moved by her sacrifice; the group seized the opportunity to disarm the slavers and moved together to escape. Mon-El helped to hold their pursuers off but saw that one of them was aiming a blaster at Kara and moved to shield her. However, a Dominator stopped the guard before he could fire and insisted that Mon-El must not be harmed before bowing to him in respect. Mon-El slightly nods at this before escaping with Kara. 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 join Kara in her work to protect people. He told her that he wanted to be a superhero on Earth just like her.

Feelings for Kara
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 Mon-El was excited to help Kara track her down. When the police were attacked by two people with Livewire's powers he and Kara 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. Kara later confronted Mon-El with abandoning the officers and Mon-El 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. He overheard Winn calling Jimmy and telling him that he knew where Livewire was even though he told the others that he didn't. He followed after them and arrived to stop the Livewire copies from attacking Guardian. However, the scientist who created them subdued them both. Kara then arrived to help free them and Livewire and together the four stopped the scientist and his soldiers. Mon-El visited Kara at her apartment and confessed that he remembered kissing Kara when he was sick. He also told her 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. He then left the apartment with the both of them awkward and flustered.

Kara ran into Mon-El as he was working in the bar where he apologized for being so honest with his feelings as he had heard that men on Earth weren't supposed to do that. Kara however, told him that she was glad he was honest and said that she agreed that the two of them weren't a good match and that she didn't feel the same way. She told him that they didn't match and he needed to keep looking until he found the right one for him. Mon-El nodded before he moved off for another part of the bar. Mon-El went off for Catco and Kara was happy to see him because she wanted to talk to him but then saw that he had been there to meet with Eve Teschmacher for lunch. When Eve left, Mon-El asked if she was okay as he had heard about the attack at the D.E.O. by the White Martians and Kara assured him that everyone was fine. Kara then asked if the lunch with Eve was a date and Mon-El told her it was as Kara had suggested that he needed to find the right one. Eve then came back and Mon-El left with her while Kara left disheartened.

Mon-El served Kara and her friends their drinks when they went to the Alien Bar to meet Alex's boyfriend though it was revealed that she was dating Maggie. Mon-El and Kara felt a little awkward around each other especially when talk of Eve came up between them. Also, that she had been seeing less of Mon-El lately because she had been busy with hero work. He later went to the D.E.O. where he saw Kara venting out frustration on blocks of concrete due to the mounting suspicion towards Lena Luthor. He told Kara that she wasn't wrong to keep believing in Lena as she had a habit of giving people the benefit of the doubt when others said not to. At first, Kara thought that he was trying to add to the mistrust of Lena but told her that he was referring to the faith she gave to him. Kara admitted that she had been avoiding Mon-El not because of work but because she was angry that he had been dating Eve. Or she was before it was revealed that they had gone on one date but it didn't end well as Mon-El had talked about Kara the entire time. Mon-El was confused as why she would be angry when she said that she didn't like him. He later visited Kara in her apartment where she admitted that she did like him. She had said she didn't because she was worried that she wouldn't be able to be with someone and still be the hero she wanted to be. However, she told him that maybe she could have both after all, with him. They were about to kiss but were interrupted with the arrival of the fifth dimensional being Mxyzptlk. When Mxyzptlk started to show off his powers to Kara, Mon-El went and angrily grabbed the being and told him that Kara was already spoken for. Mxyzptlk laughed at Mon-El as he thought that the Daxamite wasn't worthy of her and then whisked him away to the D.E.O. in his underwear. When Kara returned, he and J'onn told her all about beings like him and how his powers were on par with that of magic. He also told her that on Daxam, they had a zero tolerance policy for beings like them because although they knew 'how to party' they tended to take things too far. Kara then pulled him aside and the two of them agreed that what was about to happen before Mxyzptlk showed up was nice and they both wanted to go back to that, especially as how it was the day of Valentine. When Parasite seemingly appeared to be attacking National City, Mon-El went off to help Kara with him but they were surprised by the arrival of Mxyzptlk in a costume that looked like Superman's. It was then revealed that the imp had conjured Parasite as part of a scheme to try and show off his powers to Kara. Mxyzptlk began to mock him and Mon-El angrily suggested that he just say his name backward and go back to his dimension. Kara then asked Mon-El to leave so that they could talk in private as she felt he was starting to lose control. Back at the D.E.O. the two of them got into a heated argument. Kara was angry that Mon-El didn't tell her about the saying the name backward thing to banish Mxyzptlk but he told her that he didn't because it never works as the imp was annoying but not stupid. He then started to accuse her of being blinded by the attention Mxyzptlk was giving her and getting dazzled by his power. He believed that they should just find a way to kill him but Kara argued against it. Mon-El then stormed off to Winn who told him that he managed to find something that might work on Mxyzptlk and Mon-El swiped it. He then called out for Mxyzptlk and challenged him for Kara. Mxyzptlk accepted and transported them to a theater and got them pistols so that they could have a duel. When Mon-El received his pistol, he let out a shot immediately but it had no effect on him. Mxyzptlk easily overpowered Mon-El until he used the device from Winn to take away his powers. The two of them then fought on seemingly even grounds until Mxyzptlk got the device from him and destroyed it. He then suspended Mon-El up above the stage and prepared to shoot him with a lead bullet but Kara arrived. She said that she would marry Mxyzptlk to the shock of both men. When Mon-El visited Kara at her apartment to ask what she was thinking, she told him that the two of them were just too different and weren't going to work. He then left the apartment brokenhearted. After Kara defeated Mxyzptlk, he visited her again and she told him that she had said all that stuff to him so that he would let her go through with her plan. She told him that she didn't mean any of that stuff she said, though stressed that she didn't need him to swoop in and try and save her. Mon-El admitted that he tended to lose his head when it came to her and said that she was his Kryptonite. The two of them then spent the rest of Valentine's Day kissing on her couch.

Mon-El woke up after his night with Kara to find her missing from the room. He then turned on the news to find that Supergirl had been doing heroic deeds all morning through the city. Kara quickly returned, feeling happy. She asked Mon-El if they could keep their new relationship quiet as she didn't want to have everyone crowding around her like her last relationship. Mon-El agreed, though, as soon as they got to the D.E.O. Mon-El happily announced to everyone that they were dating. Kara then went off on a mission with J'onn to hit a Cadmus convoy and they found that they had been transporting Jeremiah Danvers. Mon-El happily welcomed Jeremiah back in front of everyone and listened to Jeremiah's story as well as warning of Cadmus' new weapon using Kara's heat vision. He then pulled Kara aside and told her that he thought Jeremiah wasn't telling the whole truth. Kara told him that he could trust Jeremiah and to not be so suspicious of him as he saved their lives. Mon-El had been invited to the Danvers' family dinner celebration but when he heard that Jeremiah was going to be given his old position back at the D.E.O. he started to protest it. He was then taken aside by Kara and asked why he was still being so suspicious and in front of her whole family. She argued about how he would feel if his father returned and Mon-El told her that he would be worried as he wasn't a nice man and he didn't think that Jeremiah was the same man that everyone remembers after years of being with Cadmus. Kara thought that it was best if Mon-El left before he upset her and her family even more. Jeremiah then offered to walk Mon-El out. Mon-El tried to explain himself to Jeremiah but he told Mon-El that he knew who he really was. He also told Mon-El that Kara would likely not like the truth and then left Mon-El alone and a bit shaken. Mon-El then told Winn of his suspicions about Jeremiah and how it had been too easy to find him after so long. He then asked him for his help in watching Jeremiah and Winn agreed though he asked for a favor in return. When Mon-El asked what it was, Winn told him to not hurt Kara. Later, he and Winn pulled Kara aside and told her that Jeremiah had tried to break into the D.E.O. mainframe as soon as he was alone which seemed to start giving some credence to Mon-El's suspicions. Mon-El met with Winn later as he was hanging out with his new girlfriend and he confessed that he wanted to not be such a terrible boyfriend for Kara. Winn told him that he shouldn't try so hard with Kara as she didn't need someone to protect her or show her off. He just needed to ask her what she needed from him. But then Winn's program located Cadmus' new weapon and Mon-El went off with Kara, Alex and some D.E.O. agents to the site but they found that it was empty. It turned out to be a distraction as Jeremiah went off to hack into the D.E.O and copy files for Cadmus and had also been enhanced with a cybernetic arm. Later, Mon-El visited Kara at her apartment as she was feeling the weight of Jeremiah's betrayal. He then took Winn's advice and asked Kara if she needed him to do anything for her and she asked for him to be there with her. He then sat and took Kara in his arms as she lightly cried into him. Winn then called and revealed that Jeremiah had taken the registration list of all the aliens living in the country.

When Kara was trying to find a way to warn people of what Cadmus was doing by abducting innocent aliens, she was advised to try and write a blog about it. Mon-El helped Kara make the choice if warning the people with the blog was the right choice which she ultimately did. However, it caused her boss Snapper Carr to fire her as she had done it without his approval even if the story was legitimate. Kara was a little sad to have lost her job at Catco but she told him that she still had her job as Supergirl and him and for now, that was enough.

Prince of Daxam
Mon-El was hanging out with Kara, watching some television when he suggested that they watch a musical, which Kara was excited to do. However, before they could do anything else, a message was sent that asked for Mon-El to be relinquished to them. At the D.E.O. they found a new ship had entered the atmosphere and when Mon-El saw the ship's image he froze at the sight of it though he claimed to not have ever seen the ship before. Kara went to investigate it but it began to attack her when she got close. When Mon-El saw that all of the ship's weapons had a lock on her, he quickly sent a message saying that he was giving himself up to them. Kara asked him why he was giving himself to them but he claimed that he had his reasons and it wasn't worth putting her or anyone else in danger. The ship teleported him to the ship but Kara grabbed onto him in order to go with him. He was shocked that she stowed away with him but they saw that all the people in the ship bowed when they caught sight of him. He then was reunited with his parents Lar Gand and Rhea where he revealed that they were the King and Queen of Daxam. Kara then realized that Mon-El was actually the prince. His parents set up a dinner between the three of them and invited Kara. He asked his parents how they were still alive and they informed him of fleeing to their ship and how they had to survive off-world after the Kryptonite rained down on Daxam after Krypton's destruction. They also informed him that they intercepted his beacon but it was incomplete which made them try to track him down. His mother informed him that they had their big break on Maaldoria where a Dominator ambassador told them that he had been there to free slaves and went to Earth. This sparked some debate between his parents and Kara on slavery before his father broke it off to ask of how Mon-El escaped. Kara wished to know as well as he had told her a lie and revealed the truth of his escape from his palace chamber and taking the Kryptonian pod from the emissary that his guard killed. Kara excused herself back to Earth and Mon-El followed. When they returned to the D.E.O. Kara was angry that Mon-El lied about his identity. He tried to explain that he knew her opinion of Daxamites and thought that she wouldn't even talk to him if she learned that he was really the prince. He said that this didn't change anything between them but she said that it changed everything as he helped lead and benefit from an awful society that preyed and oppressed people. Later, Mon-El tried again to explain himself but Kara told him that his mother had come to visit her. He asked her what she had wanted and Kara told her that she wants him to go back to Daxam with them now that the planet's atmosphere had settled but Mon-El didn't want to. Kara then told him that it might be for the best as before his parents arrived, he thought he was the only Daxamite left and he now knows that his parents, his people are still alive. She reminded him that Mon-El was a prince and perhaps it was time for him to act like one. Mon-El again tried to speak to Kara at her apartment to try and get her forgiveness but Kara couldn't find it in her to forgive him for lying for months. She told him that they had to break up and Mon-El then left brokenhearted. He returned to his parents' ship and told them that things were over between him and Kara. They believed that he was going to return to Daxam with them but he told them that he wasn't. He told them that he was tired of being served and primped up. He accused his parents of not really caring about their own people and only concerned with their own power and told them that he was done being their prince. His mother accused Kara for his behavior but he defended Kara and said that even though they weren't together anymore, being near her made him want to be better. He then demanded to be sent back to Earth and told them that they should leave the planet. His father then silently teleported him back to Earth. At the D.E.O. Mon-El gathered with everyone though Kara tried hard to not make eye contact with him. J'onn announced that they were receiving a new prisoner that was unusual from what they usually got and soon agents brought in the Music Meister. He smiled at all of them and locked eyes on Kara as he sent her into a trance. She was starting to collapse and Mon-El rushed to catch her before she fell. He watched as the Music Meister took her inter-dimensional device to create a breach as he told everyone that now he was off to find the fastest man alive. He then vanished leaving Kara in a comatose state. Mon-El and J'onn brought Kara to Earth One where they found themselves in Star Labs. He met with Barry Allen, Cisco Ramon, Caitlin Snow, H.R. Wells, Iris West and Wally West. They asked who he was and informed him that he was Kara's more than friend. He and J'onn told them about the Music Meister and how they followed him to this Earth when he mentioned that he was going after Barry next. Barry promised Mon-El that they would find the Music Meister and bring Kara back. However, the Music Meister placed his spell on Barry so that he was comatose as well. Inside their shared dream world, Kara and Barry managed to find Mon-El's musical double, Tommy Moran who was in love with Iris' musical double Millie Foss. Caitlin then informed them that both Kara and Barry were being drained of their power and that the Music Meister must be taking it for himself. When Cisco, Wally and J'onn managed to bring him in, the Music Meister told both him and Iris that if they wanted Kara and Barry back that they would have to get free themselves but the two of them could help save them if their love for them was strong enough. When Mon-El saw that Kara seemed to be dying along with Barry, he and Iris went to Cisco who helped Vibe them into their minds where they found the two of them dying from being shot. Mon-El apologized to Kara for lying to her about who he really was but she told him that she forgave him. He gave her a kiss at the same time that Iris kissed Barry and the four of them found themselves back in Star Labs where they were in one piece. The Music Meister then revealed that all of this was to teach the superheroes a lesson about love and letting the two of them be saved by it for a change. They bid all of their new friends goodbye and Kara warned Mon-El that if he lied to her again then she would (literally) drop a mountain on him. They all then returned back to Earth Thirty-Eight.

Mon-El was making Kara some breakfast and revealed that he had been learning how by reading cookbooks. Kara was impressed with how far Mon-El had come as they sat down. Mon-El then revealed that his parents hadn't left Earth and were still orbiting the planet in their ship. Their conversation was cut short when there was an alien attacking the city and Kara had to leave to handle it. Back at the D.E.O. both J'onn and Winn told the two of them that the alien had been a bounty hunter and they found a messaging device on him that announced there was now a bounty on Kara for 300 Quartz Crowns. Mon-El confirmed to Alex that it was a high bounty and it would draw in many bounty hunters across the universe to try and claim it. Kara was recommended to hide out for a while and while she argued against it, Mon-El, J'onn and Alex managed to convince her to lay low for 24 hours so they could find out who had placed the bounty. J'onn pulled Mon-El aside and told him to watch her and he promised he would though he had a lead that he wanted to run through first. Mon-El went back to the Alien Bar to wait on his parents who he summoned to meet with him. His father and mother arrived and were surprised to find that he worked at the bar but he defended his work as something he had pride in. He then told his parents that he knew that they were the ones that issued the bounty on Kara. His father and mother denied that they did though Mon-El asked them that if they didn't do it then why were they still on Earth. His mother told him that they were hoping he would change his mind and return home with them. His father told him that his mother's strength was the reason that they were able to move on after losing him until they learned that he was still alive. Mon-El returned to the apartment where Kara was with James and Winn and she was feeling anxiety about laying low. Kara asked where Mon-El was and he told her about his meeting with his parents. He claimed that even though they denied issuing the bounty, he wasn't sure he believed them. Soon after, Mon-El found that he was starting to lose control of his body. Outside the apartment was another bounty hunter who was psychically controlling Mon-El's body and used him to attack Kara. Mon-El tried to fight his control but couldn't stop himself from attacking Kara. Guardian moved in to try and stop him but Mon-El quickly threw him aside. He assault stopped when Winn found the bounty hunter and bluffed him with a threat to shoot him when he was really holding a stapler. Back at the D.E.O. J'onn interrogated the prisoner and learned that Mon-El's mother was the one that issued the bounty. Mon-El admitted that he was almost starting to believe his mother's innocence. While Alex suggested that they retaliate, J'onn informed them that President Marsdin gave orders to not engage the Daxamite ship as attacking them could spark a war. Mon-El proposed that he and Kara run away from Earth but Kara said that they can't, which he wasn't surprised that she would decide. However, he didn't see any way out of their predicament as he felt his mother wouldn't stop. Kara proposed that the two of them try to talk to his mother. While Mon-El was against it, she convinced him to try nonetheless. They went off to the Fortress of Solitude where his mother beamed down to meet with them. Mon-El informed her that they knew that she issued the bounty and asked to call it off. He told his mother that he found happiness being on Earth, and with Kara, and if she wanted to still have a relationship with him then she had to stop what she was doing. That only seemed to infuriate his mother as she told him that he could not dictate their relationship. Kara then moved in to try and reason with Rhea but she told Kara that whatever he and Kara had found in their 'tryst' was a lie and was over. Kara then started to feel weak and Rhea then revealed that she had Kryptonite weapons hidden and she struck at Kara with them. Mon-El moved to stop her but she tossed him aside. When his mother was about to fatally stab Kara, Mon-El sped off to hold her off and quickly shouted that he would return to Daxam as long as she spared Kara. Kara tried to talk him out of it but Mon-El told her that it was the only way. Mon-El was brought to the ship and his father was happy to see him again. Immediately, Mon-El demanded his mother remove the bounty and she quickly did, to his father's surprise. Mon-El then moved to watch the Earth alone from the window when he was joined by his father. He told Mon-El that he was doing the right thing by choosing to return to Daxam with them. Mon-El told him that he knew it was the right decision because otherwise Rhea would've killed Kara. Lar Gand tried to explain that he would always be Rhea's top concern but Mon-El returning to Daxam was the best thing for their people. Mon-El turned to look at the throne and told his father that if they were going to rebuild Daxam then things had to change. He said that if he was going to be king one day then he wanted to be the ruler of a new system where there was justice and fairness for everyone and get rid of rank. Lar Gand argued that it was ridiculous and not what their people needed. He claimed that their house didn't stand for centuries by giving everyone a say but Mon-El pushed that their house would've eventually have fallen. He pleaded with his father to rebuild Daxam to be better than before when his mother arrived and slapped him silent. She then commanded the guards place him into a cell for their four year trip back to Daxam in order to try and stamp out his delusions. Mon-El was in his cell when there was a flash of light and Winn appeared using the transmatter portal taken from the Maaldorians. Winn freed him from the cell and hacked the security feeds on the ship to find that Kara and J'onn were fighting his parents and their guards. He saw that Kara was in trouble against her mother and her kryptonite and ran off for them. He arrived to see his mother ready to kill Kara and quickly took one of the guard's laser staffs and shot a hole in the window. The suction force pulled the kryptonite away before Lar Gand managed to close the opening. He then watched as his father gave an order to everyone to stop as he saw that Mon-El made his choice and allowed him and his friends to leave peacefully. He and Kara then went back to her apartment where Kara confessed that she thought she had lost him. She also apologized for not listening to Mon-El as he had been right but he said that Kara wasn't wrong. He saw that his father changed as he saw that he was happier on Earth and he hoped that his mother would as well.

Mon-El was at Kara's when she came back after just saving Snapper Carr from the Biomax swarm. She had lost two leads and didn't know where else to turn to get to the truth about Jack Spheer when Mon-El told her that Lena had called to ask her for help talking out of going on a dinner date with him. The two of them then quickly went to the restaurant to crash and break the tension. However, Lena changed her mind and preferred to be alone with Jack so Kara and Mon-El took that as a cue to leave. Mon-El gave Jack a hug and told him that they should hang out sometime, man to man, and left with Kara. However, he revealed that he had did that to swipe Jack's security card so that they could get into Spheerical to find Kara's answers. Mon-El and Kara managed to get to Jack's office and into his computer to start to look through his files. They found a video file that showed that Jack had used the Biomax nanobots on himself. They then moved to save the file on a thumb drive. As they were transferring the data, Mon-El heard something and they found that the Biomax swarm was heading their way and they quickly ran out of the office before it materialized into Jack.

After Kara helped stop some bank robbers who had taken hostages, she and Mon-El went to Maggie's apartment to join her and Alex for dinner. Mon-El made a comment about not needing policemen with Supergirl around which sparked a small argument between Maggie and Kara about the ethics of dealing with normal, human criminals. He and Kara then left when the situation became awkward. The following day, they learned that Alex had been kidnapped by someone that wanted Supergirl to break a man named Peter Thompson out of prison within the next 36 hours or Alex would die. This person also seemed to know that Kara Danvers was Supergirl. Mon-El thought they should just break the man out to get Alex back but J'onn told him they couldn't do that or every bad guy out there would know Supergirl could be controlled and Maggie also knew there was no guarantee that it would get Alex back. They reviewed who might be the one doing this but couldn't come up with anything. It was eventually found out that it was an old classmate of Kara and Alex's named Rick Malverne but Kara and Maggie were able to convince Peter Thompson to tell them where Rick would hide Alex and they found her in time to save her life. When Alex was brought back to the D.E.O. Mon-El told her that he knew that she would end up okay. He then amusingly watched as Alex gave Rick a hard punch in the face before he was sent off to have his mind wiped of the D.E.O. and Supergirl's identity.

Daxamite invasion and his arranged marriage
When a psychic alien launched an attack on National City, Mon-El and Kara went to try and patrol the streets to see if they could find a lead on what happened. As Mon-El was looking around, he saw his mother leaving from a restaurant. Before he could look further into it, he was bumped by someone which made him drop his gaze and when he looked back, he found that his mother was gone. Rattled, he went back to the D.E.O. and asked Winn if his parents' ship was still in Earth's orbit. Winn told him that he tracked the ship and saw it left for Daxam weeks ago and he checked again for Mon-El and they saw that it was nowhere around. Mon-El began to believe that he just imagined seeing his mother though he felt more distraught than relieved.

He went to Kara at Catco and told her about him seeing his mother and he told her that he would've preferred to feel anger at the thought of seeing her but he didn't. Despite everything that she had done, Rhea was still his mother and he still loved her. He didn't like these conflicting emotions and told her that, during moments like this on Daxam, they liked to drug themselves so they wouldn't feel so much at once. Kara told him that it was normal and okay to feel like this and that Rhea was still his mother. Soon after, the alien that James had brought to Catco, Marcus, who was the son of the alien from before, had started to unleash his psychic powers out of nowhere. Mon-El sent Kara to change while he stayed to try and help people get away. He and James watched as Supergirl took Marcus away to try and calm him down.

At the D.E.O., they discovered that a Phorian like Marcus and his mother could be affected by ionic energy changes in the atmosphere. Kara remembered that Lena had mentioned she was working on something like that and went to call her but Rhea ended up picking Lena's phone. Mon-El was shocked that he hadn't imagined his mother and listened as she told Kara that everything that happened to the Earth would be on her head. Mon-El told his mother that her anger was with him and to not take it out on the Earth. Rhea told Mon-El that what she was doing was to finally wake Mon-El up and she then hung up. When the D.E.O. managed to find where Rhea was, Mon-El was insistent on going to confront her. He told Kara that he just needed to pick up something first. When they arrived, they found that there was a giant transmatter portal active and Lena couldn't shut it down. Mon-El realized that his mother was using the portal not to send her away but to bring something to Earth. While Kara went to try and shut it down, he watched J'onn attempt to stop his mother. But Rhea pulled out a device that she got from the White Martians which was used to trapped Green Martians in a mental state that kept them silently reliving a nightmare. Mon-El then angrily pulled out a gun with lead bullets and held it on her. He demanded that his mother stop the machine or he would shoot but Rhea told him that he wouldn't kill his own mother as he had become a hero of Earth and they don't kill their mothers. Rhea then talked about how he said that would always love her when she put him to sleep as a child. She then told him that his father Lar Gand had been so distraught when he abandoned them that he took his own life. Hearing those things made Mon-El break down and drop the gun. He then watched as ships began to come through the portal and his mother told him they were the hundreds of Daxamite ships that had the thousands of Daxamites spread across the universe. They were all arriving to Earth which she christened as their new home, New Daxam. They, along with Lena, were then teleported away to main ship.

Mon-El watched the invasion from above with great distaste and told his mother that the people of Earth weren't going to stand for this. Rhea then told him that they did indeed have to bridge the gap between their people and the humans and would through their customs of arranged marriage. Mon-El wondered who the unlucky human would be that would be forced to marry an alien invader and Rhea told him that he would marry Lena Luthor. Later, he and Lena moved to confront Rhea and told her that the two of them weren't going to get married. However, Rhea told them that there would be a ceremony and the two of them would produce an heir. Though Lena misunderstood the concept and still refused her, Mon-El told her that Rhea didn't need them to do anything for her as she only needed their genetic materials such as locks of hair to produce a child with their DNA. Rhea then brought up a children's hospital and told them that if they didn't agree to her request then it would only be the first of her targets. Both of them then agreed to marry to spare the people.

As they were in the middle of the marriage ceremony, it was interrupted by a video message from Cat Grant. Mon-El and Lena watched in good spirits as she called for the human and alien residents of National City to stand together and fight against the Daxamites. Rhea then ordered for them to be taken away while she went to oversee the quelling of the rising resistance now brewing in the city. Mon-El tried to reason with the guard to let them go but saw that it wasn't working so he moved to fight with him. Lena then took his blaster and shot the guard down which left the two of them to find a way to escape. As they were trying to leave, they ran into Supergirl, Lillian Luthor and Hank Henshaw, who had come together to rescue them. They then tried to leave through the portal that they used to sneak onboard but Lillian had rigged it to only transport her, Lena and Hank away and leave Kara and Mon-El behind before she could give the order for a Positron Cannon to fire on the ship. Kara, however, wasn't surprised by Lillian's betrayal and told Mon-El that Winn had rigged to take control of Hank Henshaw to re-open the portal should she try to do something like this. Mon-El was ready to leave but Kara told her that she had to stay and try talking Rhea down. Mon-El told her that his mother was beyond help but Kara insisted that she try as, with the cannon, there was no chance of victory. They shared a goodbye kiss before Mon-El was transported away to the fortress.

Leaving Earth
After Kara fought against Superman while he was under the influence of Silver Kryptonite and beat him, Kara collapsed. She began to dream that she was back in her apartment with Mon-El. She then told him of the time that she left Krypton when her mother gave her necklace to always be by her daughter's side. Mon-El then told her that she had to wake up as this wasn't real.

Mon-El returned back to the D.E.O. where he was reunited with Kara and formally met her cousin Superman. They told him that they found something at the fortress that could stop Rhea and her invasion, Dakum Or. At once, Mon-El's eyes widened and he told Kara that it was a bad idea. Kara quickly contacted Rhea and formally requested to perform Dakum Or, or trial by combat. Should Kara win then Rhea and her invasion force will leave Earth but should Rhea win then Earth is hers. Mon-El tried to talk Kara out of it and even suggested that Superman take over the fight but he told Mon-El that Kara beat him which officially makes her the champion of Earth and that she could win. Mon-El accepted it but told Kara that he was going to go along with her.

Later, Kara and Clark had visited Lena and Lillian Luthor as they had wanted to meet. They had a fail safe device to use to stop the Daxamites which would release trace amounts of lead into the atmosphere and make it toxic to the Daxamites. Unfortunately, this meant that Mon-El would also be forced to leave the Earth and Kara as well. Mon-El told them that if they had to, then he wanted them to use it as he wouldn't be the reason that the Earth suffers but Kara told him that if she beat Rhea then they wouldn't have to use it. When it came time for the duel, he and Kara went to the meeting spot where Rhea appeared. Mon-El watched as Kara and his mother began fighting but soon after they started, the Daxamite army began to attack the city. Mon-El told Rhea that she had just shamed herself in the eyes of the gods but she claimed that the gods wanted her conquest to succeed. Kara told him to go out and be a hero and protect the people of the city while she stayed to deal with Rhea. Mon-El moved to protect the citizens from the Daxamites attack along with Clark, J'onn, M'gann and her White Martian allies. When Lena called the D.E.O. to tell them that the device was ready, he moved to get to Kara and give her the remote to activate it. They shared a tense moment but he told Kara to do it and she activated it. The Daxamites then started to retreat as they felt the effects and the ships began to leave the Earth and stranded Mon-El and his mother. Rhea begged for her son to save her but he glared at her and angrily asked if he should save her like she 'saved' his father. He and Kara then watched as she succumbed and crumbled to dust.

Mon-El was starting to feel the effects of the atmosphere change and Alex guessed that he didn't have long before he had to leave. Kara then quickly took Mon-El to his pod so that he could escape. Before he left, he told Kara that he was a better person because of her and she will always be in his heart. Kara then took her mother's necklace and gave it to Mon-El before they shared a final kiss goodbye and Kara told Mon-El that she loved him and he told her that he loved her too. Mon-El then went into the pod as the effects worsened. He took one last look at Kara before he went and left the planet.

While traveling in space, he gave a long look at Kara's necklace before a wormhole began to open up in front of him suddenly. He had little time to react as his pod flew into it and he disappeared to an unknown space.

Personality
Prior to his arrival on Earth, Mon-El used to be a selfish spoiled brat, a party boy and a womanizer as well as being ignorant too what was going on Daxam. Despite these negative traits of his at the time, he at least cared about the welfare of his people as during the destruction of Daxam, Mon-El was reluctant to leave his people behind, he only did it because his bodyguard was very insistent; despite this, he felt guilty and undeserving of having survived while his people died.

Mon-El is light-hearted, cheerful, carefree, laid-back and fun-loving. He hates being locked indoors and loves to party. Like all Daxamites, Mon-El dislikes Kryptonians due to their arrogant and self-righteous traits, although he later warms up to Kara Danvers. Mon-El also possesses good morals, as he shows guilt and remorse for his actions.

Some people see Mon-El as a coward who runs away at the first sign of danger. However, in truth, he only avoids fights because he doesn't want to get involved unnecessarily, as well as the fact that he has no desire to become a hero. However, after some word with Alex, Mon-El begins to warm up to the idea and also develops a romantic attraction to Kara.

Since Mon-El is new to Earth, he is naïve to how things work on the planet, as well as expressions, holidays, jobs and dangers etc.; when he attempted to have sex with Eve Teschmacher (before this was prevented by Kara) she asked him if he took protection, Mon-El took this as an expression for a weapon like a sword, unaware that it actually means a condom, or when he mistakenly brought over mattress stuffing for Thanksgiving dinner. Despite this, Mon-El is very intelligent, as he is shown to have more knowledge about the universe than Kara does, due to the fact he was already an adult when he left Daxam at the time of its destruction, well Kara was in her early teens during Krypton's.

When it comes to his feelings for Kara, Mon-El tends to not think straight and loses control of his emotions, despite this, he has no blind spot when it comes to the people that Kara cares about, when Kara's adoptive father, Jeremiah Danvers was rescued from Cadmus, Mon-El was immediately suspicious of him, due to the fact that Jeremiah was Cadmus' prisoner for years and so he felt that this may have succeeded in turning his allegiance, as it turned out Mon-El was right anout his concerns the entire time.

Mon-El kept his status as the prince of Daxam secret from Kara, as he was afraid of how she would react, as he was fully aware of her dislike towards Daxamites.

Powers

 * Daxamite physiology: Normally, like all Daxamites, Mon-El's capabilities are no greater than a normal human of his physical conditioning. However, once charged by the energy of a blue or yellow sun and metabolized into his body, he becomes able to perform various inhuman feats. While generic for his race (as well as for Kryptonians), it is unknown whether Mon-El would have developed other powers had he stayed under the Earth's yellow sun for a greater amount of time.
 * Solar energy absorption: While Mon-El's powers are dependent on the energy spectrum from a blue or yellow sun, his body is able to constantly and passively absorb such energy while exposed to it, essentially keeping his reserves fully charged near-constantly. Direct exposure to sunlight will also accelerate his recovery from any injuries he does manage to sustain.
 * Accelerated healing factor: Mon-El's solar charged metabolism accelerates his healing and allows him to burn calories at a fast rate, making him resilient to weight gain. Upon being shot by a bullet made of lead which penetrated the skin of his arm, when the piece was removed he healed instantly.
 * Electrosynthesis: Mon-El's cells harness and absorbed the electrical energy surrounding him, manipulating it to regenerate himself at a cellular level and manifest his own energy source when he was comatose.
 * Contaminant immunity: Mon-El has an immunity to all forms of disease and contaminants on Earth. He also has shown himself to have a particularly high tolerance to alcohol, even those of alien origins.
 * Green Kryptonite immunity: Despite having a similar physiology to Kryptonians, Mon-El is immune to the radiation effects of Green Kryptonite.
 * Silver Kryptonite immunity: Despite having a similar physiology to Kryptonians, Mon-El is immune to the radiation effects of Silver Kryptonite.
 * Longevity: Presumably like Kryptonians, Mon-El's life-span is considerably longer than a normal human as a result of his accelerated healing factor and his immunity to contaminants, which allows his body to replace aging and damaged cells at a constant rate, thereby decelerating his aging process while also extending his life, though the upper limits of this superhuman longevity has yet to be determined.
 * Super leaping: Mon-El is able to perform incredibly high jumps in a single bound. He demonstrated this power during the attacks of the Daxamite invaders on National City, when he leaped from the ground level to the top of a nearby skyscraper, only barely bending his knees to build up momentum for the jump. This allowed him to hopscotch over the roofs of numerous buildings to get a birds-eye view of the city's destruction.
 * Invulnerability: Mon-El is essentially invulnerable to all Earthly weapons, with needles unable to penetrate his skin. He has sustained damage from meta-humans such as Livewire and recovered with little to no effect on his person. However, his durability has proven to be somewhat weaker than that of a Kryptonian's and its full extent is unknown. This is probably due to the fact that Kara Danvers has spent more time under the Earth's yellow sun than Mon-El has.
 * Super speed: Mon-El possesses the ability to move at incredible speeds, far greater than that of any normal human.
 * Super strength: Mon-El's strength is enhanced under a yellow sun, enough to easily kill a normal human if he were to attack them directly. He was able to hold his own against Kara and easily choke her when they first met. Despite this, Winn states, his strength is still not as high as hers. This is probably due to the fact that she has spent more time under the Earth's yellow sun than Mon-El has.

Abilities

 * Expert hand-to-hand combatant: As a member of the royal family of Daxam, Mon-El is a capable unarmed fighter. Training with Kara further improves his fighting skills. His fighting skills have greatly improved to the point where he was able to take on and defeat highly trained Daxamite soldiers relatively easily.
 * Expert stick fighter: As a member of the royal family of Daxam, Mon-El is a capable stick fighter. He was able to defeat highly trained Daxamite soldiers with little effort.
 * Expert marksman/Firearms: Mon-El has proved to possess a certain level of knowledge on the use of firearms.

Weaknesses

 * Lead: Weapons made from lead will penetrate Mon-El's skin; if lead stayed in his system for too long, he will die from the poisoning. Due to him having spent over a year exposed to Earth's yellow sun-enriched atmosphere, Mon-El is able to endure it's poisoning effects for much longer than most Daxamites.
 * Extreme energy: Extreme amounts of energy, such as Livewire's electricity, while she is at her peak, can be enough to kill Mon-El.
 * Electricity: Despite his invulnerability, Mon-El seems to be vulnerable to large amounts of electricity. This was seen when fighting against Livewire.
 * Red Sun energy: Like Kryptonians, exposure to the Red Sun will make Mon-El the equivalent of a human being on Earth.
 * Magic: Mon-El is not invulnerable to magic because his powers come from his natural physiology and not supernatural means. Mr. Mxyzptik was able to easily teleport him away to the D.E.O's office in only his underpants in an instant.

Trivia

 * Mon-El has similarities to Oliver Queen; they were both initially selfish spoiled brats, rich playboys and womanizers, but they ultimately change their ways after a near-death experience.
 * Despite his name ending with "El", Mon-El is not actually a member of the House of El.

Behind the scenes

 * In the DC comics, Mon-El (alternatively spelled as M'Onel) is the alias of Lar Gand, a Daxamite superhero inspired by a young Superman. He has been also known as Valor.
 * In the DC comics, Lar Gand was an amnesiac who was given his famous alias of "Mon-El" by Superman. The name is derived from the day he arrived on Earth, Monday (Mon), and Kal-El's own Kryptonian family name (El) as he had believed him to be not only a fellow Kryptonian but his brother before his Daxamite physiology was revealed.
 * Alternatively, in the post-Zero Hour version, Lar gets the name "M'Onel", which is the Martian word for "Wanderer". Moreover, in real life, Monel is the name of a group of nickel alloys.
