[DC] The Nobody Is Causing Trouble Again Today

He's just an ordinary Gotham City citizen. He has no superpowers, no money, and he can't exactly be called handsome. Aside from the occasional stay at Arkham, his only real superpower is that he's got great stamina [not that kind]. Of course, it's not that he has no powers at all. It's just that there's a bug: every time he uses his ability, he loses control. And he can't be killed. You could say he's immortal, and his body heals quickly. But he has no idea what happens while he's using it, so he only ever does so in the most desperate situations. He doesn't even know what his ability includes.

A story about an ordinary Gotham City resident who moonlights as an Arkham inmate, hooking up with superheroes and villains.
