Mon-El

Mon-El (also known as Mike Matthews) is a Daxamite, hailing from a planet called Daxam who crash-landed on Earth.

Daxam's demise
Mon-El worked as a palace guard for the royal family of Daxam. The day Krypton was destroyed, its debris showered on to the sister planet, causing multiple casualties. Mon-El tried bringing the prince to safety when they spotted a functional Kryptonian pod. Mon-El instantly decided to send the prince away, but the prince locked him in the pod instead and sent him away.

Landing on Earth
The pod travelled passing the Well of Stars, before eventually finding its way to Earth where it crash-landed. Supergirl quickly discovered the pod, and she and J'onn J'onzz took the man to the D.E.O. for tests. However, they discovered that he had skin that could not be penetrated by a needle and so the man remained comatose.

Escape from the D.E.O.
He eventually came to and escaped into the city, and found his way to a station in hopes of sending a signal to his planet. The signal was detected by Winn and Supergirl, upon finding out he was from Daxam and fearing that he was behind the attack on President Marsdin. Supergirl apprehended Mon-El at the Mount Pride Observatory and temporarily incapacitated him. The next day, she apologized for her prejudice after realizing Mon-El wasn't behind the assault. 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.

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

Powers

 * Daxamite physiology: Mon-El didn't used to have super powers on Daxam, due to the fact the planet's orbiting a red sun which negated their physiology. Like Kryptonians, it is possible for Daxamites to gain powers from a yellow or blue sun.
 * Invulnerability: Mon-El's body is impervious to disease and damage than a normal human's, as needles couldn't penetrate his skin; the full extent of his durability is currently unknown.
 * Super strength: Mon-El possesses an incredible amount of strength, as he was able to temporarily hold his own against Kara and easily choke her. Although Winn states, that his strength is not equally as high as Kara's; however, it is likely because Mon-El had just came out of a coma and is not yet at full strength.
 * Super speed: Mon-El is able to move, react and think at amazing speeds far exceeding that of a normal human.
 * Super leaping: Mon-El's incredibly strong legs have the ability to do incredibly high jumps in a single bound.
 * Photosynthesis: Mon-El's cells harness & absorbed the electrical energy surrounding him, manipulating it to regenerate himself at a cellular level and even his own energy source when he was comatose.

Weaknesses

 * Green Kryptonite: Mon-El appeared vulnerable to Kryptonite radiation when the D.E.O. used it to make him weak while he was in a comatose state.
