Forgot about Issac Mendes and Sylar.....
Issac Mendes: The Vision Painter.
Sylar: Death Seed (but I think Sylar might be more suitable as it is).
Peter= Powers of a god and in a constant state of confusion, maybe 'I don't know what's happening please tell me what to do Guy.
Matt= He's dumb and can control your mind, maybe Mindworm, or Brain Insect, or Professor D.
Claire= I think she will live forever, so maybe 'Immortal Jailbait Girl' or 'Someday I might ride your gradchildren Girl'.
Hiro= The Traveling Man ( unless they introduce a hero with space travelling powers, in which case he should get the name, and be played by Peter Stormaire)
Adam: Russell Nash
Here's mine:
Peter = Peter
Nathan = Nathan
Matt = Matt
Claire = Claire
Nikki/Jessica = Nikki/Jessica
Micah = Micah
Hiro = Hiro
Monica = St. Joan
Sylar = Sylar
etc.
