Mysterion is the superhero alter ego of Kenny McCormick! He’s wearing a purple cape with a hood and a question mark on his head. He’s wearing a purple shirt with a letter M on it, a pair of purple pants and an underwear on top! His power is that he can’t die, because if he dies he will wake up in his bed. And he’s basically the batman of South Park!
Mysterion: *dies*
*in kenny’s room*
Toolshed: Dude, Kenny, what'd you run away for?! We've gotta fight these guys!
Mosquito: Yeah, come on, get your costume on, lazy-ass!
