It has been confirmed that the Seattle Superhero is not Superman, Batman, Spiderman, or any of those other superheroes who people look to to save their miserable lives from the "baddies".
Seattle's Superhero is just plain old Benjamin Fodor, alias Phoenix Jones and he was forced to reveal his real identity in front of the court because the judges thought he looked rather stupid in his mask.
After revealing his true identity he put his mask back on and flew out of the courtroom to confront the local press. He has told Seattle not to worry because he's going to clean the place up single-handed. He will defeat all of the evil characters who haunt the place at night, get rid of all of the junkies, alcholics and general scum. And after a hard days night, go back to the day job, a refuse collector (pretty cleaning up job too).
He also revealed to the press that he was not the son of murdered, mega-rich parents and has no connections with Kryptonites who constantly attempt to destroy him. He also revealed that he loves pussies because Catwoman once bedded him, but that's a different story, miaow!
Outside of the court two men dressed in white were waiting with a straight-jacket, but Phoenix just managed to escape and "flew over the Cuckoos nest!"
