Mon-El

Mon-El is the former 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 king Lar Gand and the late queen Rhea, the ex-boyfriend of Kara Danvers and the husband of Imra Ardeen. While adjusting to living on his new home world, he began to use the identity Mike Matthews.

When Mon-El was exposed to Earth's atmosphere filled with lead, he was forced to leave both Kara and Earth to find a habitable environment for his physiology, but entered a wormhole in the process. He arrived in the 31st century, where L-Corp had cured him of his lead allergy and he and Imra eventually got married and then later worked with the worlds' governments to form the Legion, a team of superheroes that followed in Supergirl's image and morals.

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 known by many as the "frat boy of the universe". While he was still on Daxam, 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 he never tried to stop it, 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 beings, and grew to both dislike and distrust them, firmly believing the only way to deal with them is to kill them quickly.



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 when he did so, he choked Supergirl and threw her across the room because he saw that her chest crest was a Kryptonian crest. The D.E.O. went into high alert and he started to panic and look for an escape. When he was confronted by guards, he was surprised by his new strength and speed before he escaped into the city. He started to ask around for a place to make deep space transmissions and eventually found his way to a satellite station in hopes of sending a signal to his planet. The signal was detected by Winn Schott and Supergirl, and upon finding out he was from Daxam and fearing that he was behind the attack on President Olivia Marsdin she rushed to confront him. The two quickly brawled against one another until Supergirl managed to incapacitate him. He was thrown into a cell where he was confronted by Supergirl who he quickly began to despise. They argued for a long time 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 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 not believing him because she found the actual culprit. When he asked if she could help him contact his home 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 lied and told them 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 able to understand why he wouldn't be safe.



After promising Supergirl that he would stay at the D.E.O., Mon-El managed to convince 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 ended up breaking the wrist of the man that he was playing against. Another man 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 how terribly different they are from each other. 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 be his mentor and train him. He says that nobody would have thought it possible for a person from Daxam and a person from Krypton.

Soon after, Kara asked Winn to make Mon-El a fake ID as "Mike Matthews", and arranged him a job as an intern at CatCo Worldwide Media. While Kara tried to coach him in human customs and work ethics, he resisted the lifestyle of a person with a desk job, refusing to do any work and almost engaging in office sex with Eve Teschmacher. He met Kara at an event held by Lena Luthor and they danced while James Olsen and Winn secretly wondered if Kara could be into him. Mon-El attempts to help Supergirl fight the thieves that crash the party and gets temporarily knocked out because he wasn't competent at fighting. Eventually, he was fired from CatCo, then Kara, under Alex Danvers' advice, tells him that she should not try to force him to live the way she does 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. Mon-El did not care that he was wrong to work together and tells Kara that he is in her hands.

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. Motivated 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 rtrying to redeem himself, Kara sweetly thanked him, while also noting Guardian's contribution.

That night, Mon-El wandered the streets. Approaching what appears to be a sick homeless man and asks him how could he help him as he wants to be better. He was then subdued by the man who was an agent for Project Cadmus. He was transported to a Cadmus facility, where he manages to escape from his cell. Lillian Luthor shows up and brings out who appears to be J'onn J'onzz when it is actually Hank Henshaw and threatens to hurt him.Mon-El agrees to return to his cell. Supergirl was then baited to rescue him. After threatening to kill him with lead, Lillian 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. Mon-El was about to tell Kara something about Daxam but he was interrupted when 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. He then asked Winn and James if Kara was "mated to anyone" and explained that in Daxam they had arranged marriages. Winn says that in Earth people choose their own mate and Mon-El asks if she has chosen. James replies that she has not. Mon-El says that he only asked because he was studying Earthly customs but is looking at Kara intensely.

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, he entered the bar again trying to help and as a consequence of that Mon-El was exposed to 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 risked her life trying to save his life like she does to all people.

Once he was stable Kara spoke with him and apologized as it was her birth father who created the Medusa virus. Mon-El told her that he didn't blame her or her father and then moved to kiss her without her consent before he passed out, saying that she was beautiful.

Eliza Danvers was able to extract a sample of the virus to create a cure. After he recovered, Kara wanted to speak about what happened he told Kara that he had no memory of his time being sick, so they didn't discuss him 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. Kara came to bar to speak to Maggie about investigating the disappearance of Izzy Williams. Mon-El later visited her at CatCo and then decided to help her to impress her.

Fighting Mr. Mxyzptlk
Just as Mon-El and Kara are about to kiss, Mr. Mxyzptlk appears in her apartment and tries to woo Kara with his powers though Mon-El tried to stand in his way. He easily banished Mon-El to the D.E.O. before returning to woo Kara and used his powers to put her in a wedding dress. When Kara tried to stop some thieves, Mxyzptlk arrived and made their guns fly off their hands, though he easily turned them on the thieves themselves and Kara just managed to stand in the way and stopped them from getting shot.

Soon after, Parasite was attacking National City and Kara and Mon-El went to engage him before Mxyzptlk arrived, wearing his version of Superman's suit to try and save everyone. Mon-El, however, saw through the act and knew that he conjured the creature to try and 'play the hero'. Mon-El demanded that Mxyzptlk just say his name backwards and return to his dimension and Kara was surprised that was the way to banish him. Mxyzptlk then made Kara an ultimatum, agree to marry him or he would unleash havoc upon the people of Earth.

Mon-El went out and called Mxyzptlk out and challenged him to a fight. Mxyzptlk accepted and transported them to a theater where he conjured them pistols. Mon-El took his and immediately shot him though it did nothing. Mon-El then revealed that he took an energy dampener from the D.E.O that would render Mxyzptlk powerless. They fought hand to hand though Mxyzptlk managed to swipe the dampener from Mon-El and reversed it, giving him his powers back. He bound Mon-El and was about to shoot him with a lead bullet but Kara arrived and agreed to marry him. She told him to go to the Fortress of Solitude at noon the following day.

Eventually Mon-El and Kara realized that the only way to defeat Mxy was to get him to say his name backwards, which they successfully did by putting the Fortress of Solitude on lockdown. Mxyzptlk began to panic and asked Kara to not do this. She revealed that there was a code to de-activate the self-destruct sequence. They went to the control panel where she pointed out the buttons to punch in the code and Mxyzptlk managed to stop it before it was too late. However, the code was revealed to be 'KLTPZYXM' and he began to fade back into his dimension. He told Kara that all he wanted was to have someone love him but before he vanished she told him that love had to come and find him, not have it forced on anyone.

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 telling her that she would never be alone as she would always be in her daughter's dreams. Mon-El then told her that she had to wake up as this wasn't real and she was at the Fortress.

Mon-El was at the D.E.O. where he hugged Kara when she returned from the Fortress. He then met her cousin Superman. They told him that they found something at the fortress that could stop Rhea and her invasion, Dakkam Ur. 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 Dakkam Ur, 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 because he had no faith in her; but Superman told Mon-El that Kara beat him which officially made her the champion of Earth and that she would win. Mon-El reluctantly accepted that Kara was going to fight his mother.

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 killing to the ones staying on Earth. They realized that this would mean that Mon-El would also be forced to leave the Earth.

Kara and Clark returned to the D.E.O. to tell them about this plan and Winn said that this surely wouldn't mean that Mon-El would have to leave. Clark said that he would probably survive a bit longer because he had been exposed to the yellow sun for months but he would need to leave Earth to survive. Winn was sent to help Lena with the device.

When it came time for the duel, he and Kara went to the meeting spot where Rhea appeared with a soldier. He told Kara that he was there for her. 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 for not following their sacred law and killing his father; which was the only reason he turned against her, but she claimed that the gods only cared about her victory. He then jumped off the building and left.

Because Kara told him to, Mon-El fought alongside Superman, Martian Manhunter, M'gann M'orzz and her White Martian allies. They successfully beat the trained Daxamite soldiers who called him a traitor.

When Lena called the D.E.O. to tell them that the device was ready, he moved to get to Kara. They realized that the invaders were about to destroy the city so he nodded, telling her to activate it. The lead was dispersed in the atmosphere and 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 her son to save her but he glared at her and angrily asked if he should save her like she "saved" his father.

Mon-El started to cough and wheeze and feel the effects of the atmosphere change. Kara asked Alex what to do and she said that they probably had a few minutes before he had to leave Earth. Kara then quickly took Mon-El to his pod so that he could escape while e was coughing and wheezing. Mon-El then went into the pod as the effects worsened.

While traveling in space, Mon-El gave a long sad look at Kara's necklace before a wormhole unexpectedly opened up right in his direct course. He barely had any time to react to this as his pod flew into it and he was whisked away to an unknown space. The wormhole then closed up behind him.

Traveling to the future
The wormhole that Mon-El entered was actually what is known as a 'disturbance' which propelled him forward in time. He arrived back on planet Earth but in the 31st century. There, he was administered a cure to his allergy to lead which was developed by L-Corp about 400 years after he had left. He met Imra Ardeen as well as other aliens and powered individuals as he tried to find some way to return to the 21st century. According to Imra, during the time Mon-El was in the 31st century, he wouldn't look at another woman for years and mostly kept to himself until he finally gave up on finding a way back to the 21st century.

He saw the chaos and problems that the Earth was having in the 31st century and he used Supergirl as inspiration to rally all the powered people he met into a group of heroes and led them in their mission to protect the Earth and beyond. They went on to call themselves The Legion. After a time, he fell in love with and married Imra.

Returning to the 21st century
The Legion learned of a world that was dying and they retrieved the data to save it against the dark threat it was under and hid it in their DNA for safe keeping. They then took off in their ship to save that world but got hurled into a wormhole and they ended up thrown back in time and crashed on Earth over 12,000 years in the past. They could not find a way to return to the future and realized that their only choice was to enter hyper-sleep and wade out time until they returned to their proper century. They waited out in the bedrock and set the ship's system to wake them from their cryotubes when it was the right time.

When the ship's defenses were activated, Mon-El awoke and quickly saw that there were intruders. He took a blaster and fired a warning shot while yelling at them in Saturnian. He then saw that it was Kara, J'onn and Winn. He was taken to the D.E.O. where everyone was surprised that he was breathing normally despite the air still being toxic to Daxamites. He gave vague answers to all of them about where he had been and what he had been doing on the ship until Kara shooed everyone away so that he could get time and space to rest. Kara told him that he had been gone for seven months which shocked him.

After he had rested enough, he snuck out of the med bay to steal a power source from the D.E.O. storage room but was confronted by two guards. He beat them up badly but was quickly attacked by Kara and then thrown into a cell. She began to wonder if it was really him and Mon-El told her that it was. She wondered what had happened to him and he responded simply with a lot. She couldn't understand how he had changed so much and started to beat herself up for hoping as a human would, which he absorbed all in silence.

He was then visited by Winn, and though he expected not to get any answers from Mon-El, he told him that he was trying anyway. Mon-El told him that he needed Winn's help as a friend to return to the ship. Winn initially refused but Mon-El quickly told him that if he didn't get back then a lot of people, including Kara, would be in danger.

Winn freed him from the cell and went with him back to the ship with the power source he had tried to steal before. He checked the other pods to see if they were still working but they were stumbled upon by Kara. She wondered why Mon-El was so different after only seven months but he informed her that he was gone for seven years. He explained about his trip to the future and that he had been living on Earth in the future. Kara accused Mon-El of forgetting about her even though he was still wearing her necklace. But an alert sounded that the life support to the pods was failing. He managed to reroute power to all but one of them. He saw that it was Imra's pod and that she was drowning. He rushed to break it open but couldn't as it was pure dwarf glass. Kara moved to break it and free Imra and Mon-El saw that she was still breathing. They quickly brought her to the D.E.O. to be healed.

Imra was brought to the medical bay where he explained that Imra was from Titan. Kara asked him just who she was but Mon-El didn't answer. He simply asked to be notified when she woke up. Mon-El and Kara went out to the terrace where he explained that he never forgot her and kept the necklace to remind him of all he had learned while he was with her and everything she had done for him. He then told her that he thought he would never see her again and tried to move on. He explained that he had been secretive because he didn't want to hurt her but he now remembered that she didn't need him saving her. Their time was interrupted by Imra who had awakened. He was delighted to see her and moved to embrace and then kiss her. He then introduced Imra to Kara and told Kara that Imra was his wife.

When Kara went off to fight against a Dominator, he went to try and check on her but Alex told him that she was fine because she is Supergirl. She then left him with that.

Mon-El and Imra informed the D.E.O. of how they had wound up back in the past and asked if there was a chance that the D.E.O. could help them fix their ship. J'onn informed him that they would do all they could to help but, for now, they would have to settle in. Kara invited him and Imra to her house for a Christmas party but Mon-El told her that he and Imra couldn't make it as they had to focus on working on the repairs.

Mon-El then took Imra off to the Alien Bar where he introduced her to ribs. They were having a good time before Kara and Winn surprised them. Imra tried to strike up some pleasant conversation. When Winn took Imra away, the two were left and started talking awkwardly with one another. Kara was then called away.

Mon-El went to train with Imra and she took a surprise shot at him, to his amusement. He then went to playfully entrap her in a hold as the two of them laughed together.

Mon-El and Imra went to see Kara as she was brought into the D.E.O. beaten and injured from her battle with Reign.

When Kara had slipped into a coma, Mon-El went to wake up his fellow Legion member QuerlDox/Braniac 5 in order to help her. They put Kara in one of their suspension chambers in the Legion ship as Querl plugged directly into her mind through a neural implant. He told Mon-El and the others that Kara seemed healthy but couldn't wake up for some unexplained reason.

When Reign started to terrorize the city, Winn pointed out that they had Mon-El and his friends to help but he quickly told them that they couldn't interfere. He told them that it was complicated but did inform them that history shows that Kara does come through and Reign does eventually leave. J'onn then revealed to them that the D.E.O. had a contingency plan in case Superman ever turned against them that they could use on Reign instead.

When J'onn's plan failed to stop Reign and Alex had been hurt, Mon-El revealed why the Legion couldn't help. They explained of the world in the future that was dying and of the data in their DNA they were protecting. Should one of them die, then the data would be lost and that world would be doomed in the future. After analyzing Reign's pattern, they saw that she would go on to target the National City prison to kill everyone there, both the inmates and the guards. After speaking with Imra, Mon-El decided that though their mission for the future was important they couldn't just stand by when there were people then and there that needed them. He, Imra and Querl then went off to don their Legion rings and head into battle.

Mon-El and Imra flew over to the prison while Querl piloted the ship. Reign met them in the courtyard where they went into battle. While Querl was firing on her from the ship, Mon-El and Imra tried to bring her down with force but she was able to fight through their efforts. She used her freeze breath to trap Mon-El in a block of ice before she went to attack Imra. Kara was able to awaken from her coma and quickly joined the fight but was still too weak. However, they managed to inject a tranquilizer dart full of Kryptonite into Reign which made her retreat.

Later Mon-El admitted to Kara that he never wanted to be a hero, and that he still didn't want to be one, but was a vigilante regardless because of her.

Personality
Mon-El was proven to be a selfish, spoiled, party boy and womanizer, who has horrible beliefs and morals; which were all traits that were shared with all Daxamites elites according to their reputation of hedonists. He was not at all ignorant to anything that was going on Daxam. Despite these negative traits of his at the time, Mon-El at least cared about the welfare of his people seen during the destruction of the planet where he was reluctant to leave his people behind.

Mon-El was egotistical, misogynistic, careless and self-loving. He hates being inside and indoors and loves to party. He usually tries to make negative feelings go away with inappropriate jokes, sex and other inappropriate activities that he so loves.

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 possessed bad morals, as he showed very little guilt and remorse for his actions, for example, that he tricked Winn Schott into letting him go to a bar. He was disrespectful of women in power positions, including his mother and Kara and has made it very clear that he thinks all women fawn over him; i.e., when he propositioned Maggie Sawyer and Alex Danvers (who are both out lesbians) to have a threesome with him.

Mon-El kept his status as the prince of Daxam secret from Kara, as he was a coward and afraid of how she would react, as he was fully aware of her dislike towards Daxamites. Most people see Mon-El as a coward who runs away at the first sign of danger. He has expressed that he thinks that this is the clever thing to do as it was dangerous and had no desire to become a hero.

Since Mon-El was new to Earth, he was 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; he also mistakenly brought over mattress stuffing for Thanksgiving dinner instead of Turkey stuffing.

Despite this, Mon-El is semi-intelligent but still highly incompetent, as he is getting used to earthly customs in a few months, being mostly successful. He is also intuitive, correctly identifying Jeremiah Danvers as a potential threat and his parents as the ones who hired the bounty hunter. Mon-El is displayed to have about the same amount of knowledge about the universe than Kara does, as he is aware of how Fifth-Dimensional beings could be banished back to their dimension by getting them to say their name backwards, due to the fact he was already an adult when he left Daxam at the time of its destruction, while Kara was in her early teens during Krypton's demise. He learned these traits when he was on Daxam and saw nothing wrong with them, seeing people of Earth as uptight because they disagreed with him.

When it comes to his feelings and beliefs,. Mon-El tends to not think straight and loses control of himself. Because of this, he is not blind to when it comes to the people that Kara cares about, when Kara's adoptive father, Jeremiah Danvers was seemingly rescued from Project 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; it turned out he was right about his concerns the entire time.

Mon-El loved both his parents, Lar Gand and Rhea (at first) very much, however, their relationship became strained due to the fact that he had become a different person so that he could be with Kara, despite the fact that he believed his father was not a good man, he still loved Lar Gand and was devastated on learning that his father had (supposedly) committed suicide, because he chose to stay on Earth; leaving them.

However, when Rhea began the high invasion of Earth, upon realizing that his mother had gone too far, Mon-El was willing to kill her with a gun full of lead bullets and is only deterred when she lies by telling him that Lar Gand was so upset with Mon-El leaving them that he took his own life. Kara later informed Mon-El that Lar Gand did not commit suicide, but was murdered by Rhea - and so - enraged and disgusted by Rhea's actions, Mon-El wanted to take her down; so he said he saw his mother as an irredeemable and immoral person, who bore no guilt, shame or remorse for her action (just like himself in the past). Thus, in her final moments, when Rhea asked Mon-El to save her - he refused and coldly asked if he should save her the way she "saved" his father; and he allows her to die.

After 7 years of being in the future and being part of the Legion, Mon-El has matured somewhat. He also has a bit more wisdom as he was able to help Kara through bouts of emotional crisis during her times against Reign.

Mon-El loves his wife Imra Ardeen, however, it was later revealed to be an arranged marriage, although the two later did (genuinely) fall in love with each other, however, Mon-El's romantic feelings for Kara; are stronger then his romantic feelings for Imra, which caused him to emotionally cheat on her and pine after Kara until he was forced to leave Earth for the second and final time.

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 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 if Mon-El will developed other powers as well.
 * Solar energy absorption: While Mon-El's powers are dependent on the energy spectrum from a 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.
 * Kryptonite immunity: Despite having a similar physiology to Kryptonians, Mon-El is immune to the radiation effects of Kryptonite; such as Green Kryptonite, Red Kryptonite and Silver Kryptonite.
 * Longevity: Like Kryptonians, Mon-El's lifespan is considerably longer than a normal human and likewise ages much slower. After being in the 31th century for 7 years, he looks exactly the same, when he first arrived on Earth in the 20th century.
 * Super jumping/leaping: Mon-El is able to jump several feet off the ground and leap several stories in a single bound without having to fly. 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 bird's-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. Despite being cured of most of his lead weakness, he is stuill vulnerable to lead bullets and other lead weapons.But He survived a RPG exploding at close range without even any bruises, so his invulnerability to anything leadless is still expansive.
 * Super speed: Mon-El possesses the ability to move at incredible speeds, far greater than that of any normal human. He was able to run through the halls of the D.E.O. in a split second, seen as a blur to the naked eye. Despite this, he is not as fast as speedsters such as Barry Allen and Wally West respectively.
 * 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 Kara has spent more time under the Earth's yellow sun than Mon-El has.
 * Lead immunity: After taking a cure when he traveled to the 31st century, Mon-El is no longer vulnerable to lead and can easily withstand Earth's lead-contaminated atmosphere, but is still successptible to Lead weapons.
 * Abilities via Legion Ring: Each member of the Legion is granted a special ring that serves as a form of identification, along with granting each member several other capabilities.
 * Flight: The ring that brainy invented for the legion has been seen to enable Mon-El the ability to fly through unspecific means. It seems to be activated through a telepathic suggestion, as no thoughts or movements were taken to activate it. It appears that it allows Mon-El to fly in a more hover-like stance rather than the typical vertical form of flying found in Martian Manhunter or Supergirl.
 * Telepathy immunity: The ring that Brainy invented for the legion has been seen to give Mon-El the ability to resist telepathic abilities such as when M'yrnn J'onzz loses control in the D.E.O. and cause everyone to display violence towards each other.

Abilities

 * High-level intellect/Expert tactician/Leader: Mon-El has a very high intelligence due to him growing up in an advanced civilization as well as having knowledge about other alien species, their abilities and heritage. He has also become more calmer, focused and significantly wiser. He is also capable of utilizing futuristic technology without any doubts, confusing and hindrance. As a former member of the royal family of Daxam, Mon-El is a capable leader and tactician; as he founded and leads his own team of heroes known as the Legion. He can also analyze the fighting styles of Reign to determine her strengths and weaknesses in order to determine when she is at her strongest and when she is most vulnerable.
 * Multilingual: Mon-El is capable of fluently speaking English and Saturnian.
 * Expert manipulator: As seen on multiple occasions, Mon-El has been able to lie, or charm his way out of consequences, and has even made Kara feel wrongfully guilty for things that he had done.
 * Expert combatant: As a member of the royal family of Daxam, Mon-El is a capable unarmed fighter. Training with Kara further improved his fighting skills. He was able to defeat Guardian and almost was able to kill Kara, though he was being controlled. His fighting skills have greatly improved to the point where he was able to take on and defeat several highly trained Daxamite soldiers with armors and weapons with relatively ease. After returning from the future, he has shown tremendously improved combat abilities, utilizing his reflexes and strength with extreme focus and technique, even learning how to fight with a cape allowing him to easily overpower Supergirl. He would later teach her how to fight with one. He was however easily beaten by Purity and even with Imra Ardeen's help, they were beaten by Pestilence. But together with Supergirl, using the capes from their suits, they could fight Reign to a stalemate.
 * Expert stick fighter: As a member of the royal family of Daxam, Mon-El is a capable stick fighter. His fighting skills have greatly improved to the point where he was able to defeat highly trained Daxamite soldiers with little effort.
 * Expert marksman: Mon-El has proved to possess a certain level of knowledge in the use of firearms.

Weaknesses

 * 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: Mon-El is powerless when exposed to the energy of a red sun.
 * Blue sun energy: Mon-El is powerless when exposed to the energy of a blue sun, its radiation is also fatal to him as well as all men.
 * Magic: Because his abilities stem from his natural physiology and not supernatural means, he is vulnerable to mystical power as any mortal or Kryptonian.

Former 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 a few months exposed to Earth's yellow sun-enriched atmosphere, Mon-El is able to endure it's poisoning effects for much longer than most Daxamites. Later, with science provided in the 31st century, Mon-El was given something that helped him stay alive even longer with lead in his system, but he will still die if he is exposed to lead for extended periods of time.

Equipment

 * Old Legion suit: After Winn Schott fixed his old Legion suit, Mon-El started wearing it to help Kara Danvers train. It carries a hollowed out House of El symbol in the middle of the chest, likely in regards to Supergirl, with a cape that's made of a special kryptonian material.
 * Legion flight ring: Mon-El's legion ringwas built by Brainy, and it allows him to fly.
 * Healing technology: A advanced piece of futuristic technology on his belt allowed Mon-El to heal a young boy and save his life.

Former equipment

 * Legion suit: Mon-El wore a black suit that protected him in battle. After Winn Schott repaired his old suit, Mon-El has stopped wearing this suit.

Trivia

 * Mon-El has similarities to Oliver Queen; they were both initially selfish spoiled brats, rich playboys and womanizers, but ultimately change their ways after a near-death experience. They also both love cooking for their girlfriends.
 * Despite his name ending with "El", Mon-El is not a member of the House of El.
 * Mon-El has had three known love interests, listed in order as follows: Eve Teschmacher, Kara Danvers and Imra Ardeen.
 * Mon-El's superhero name, Valor, has never been used in the TV series, only in official media.
 * Mon-El is actually technically over 12,000 years old, since he time-traveled back to the distant past and went into cryo-sleep until waking up in the present.

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.
