(updated to OYL)
Code Name: Doomsboy
Real Name: Still Doomsboy(What? You think he can just put on some glasses and look like a normal person?)
Team Affiliation: Young Injustice(former), DV8(former), Outsiders(from time to time anyway)
Age: 19 (though his growth was accelerated so technically 4 or 5)
Appearance: Bigger than average with gray skin and white, jagged bones poking out. Wears black jacket, shorts and boots. Look at the picture, darn you!
Abilities: Super strength, Invulnerability, The ability to evolve beyond an opponent.
Weaknesses: While Doomsboy may not be an idiot he certainly isn't the smartest guy in the world either. Also there's more of a chance he'll be vulnerable against something he's never faced before.
History: When Superman was killed by Doomsday, the scientists at Cadmus slaved to create a new Man of Steel as a replacement. And eventually finding a way to combine what they could understand of Superman's DNA with Lex Luthor's, made Superboy. But this didn't happen in every reality. When Bedlam got his magical powers back he messed around with Young Justice's origins so that they'd cease to exist. One of those changes was discouraging the Cadmus personel against trying to figure out the Kryptonian genes since they'd already broken down Doomsday's.
And so they stopped the production of the Superman clone and made one of Doomsday instead. After all, who better to replace the world's greatest hero than to clone the monster that killed him? (What? That doesn't make any sense you say? Pshaw!) Anyway, while we don't know for sure whether Westfield or Luthor's the human donor, the assumption leans more towards Westfield. Immediately after getting out Doomsboy made an impact on the world as a hero....just not necessarily a good one. Not only did he charge the innocents to protect them, but he often killed his adversaries, hiding his growing disgust for the one he was cloned to replace.
Eventually the president had enough and wanted to take Doomsboy out but did give his "brother" Conal, the Superman clone that was stopped in mid-creation, to try and plead with Doomsboy and wanted to help him change his ways. It's nice to want things. Long story short Doomsboy waged war on the army but conveniently enough this was when he was enlisted by Bedlam to help with the slowly reforming Young Justice. After Bedlam's defeat, Doomsboy was seemingly erased from existance as the world returned to normal.
Additional History: Acolyte, a previous Young Justice villain, kept with his plan to replace the current God with a new one. With an unexplained power boost he was able to bring to life beings who normally wouldn't be able to exist. First he summoned Harm, who was dead at the time, and tested him out on the Titans before he'd grant him godhood. But due to intervention by Batman, Harm was defeated. Because of Harm's failure Acolyte summoned a new being into existance, Doomsboy. Once again being called to replace someone, Doomsboy made short work of Harm but failed to finish him off causing Harm to find the Titans and eventually join them, defeating Doomsboy in the process.
Shortly afterwards, he joined a supervillain team dubbed Young Injustice in an effort to take down the teen superheroes. After the team failed and disbanned, Doomsboy went on his way. After awhile of wandering around randomly Doomsboy was found by Ivana Baiul and due to some manipulation by Bliss of the Deviants ended up joining them. When they were attacked by the Titans and Young Justice, it was revealed that Bliss didn't control Doomsboy for long, he was just with them willingly because she was hot. But after she tried to enforce her rule over him, he turned on her and helped the good guys win. It was a mutual decision that he wasn't going to be with the Titans and after some searching he ended up joining the Outsiders. Though I wouldn't exactly call it a full membership, he pretty much comes and goes as he pleases, randomly showing up from time to time.
