Some interesting things on that site.
I agree that Hiro and Peter are safe...once Peter is gone, where is the threat? unless the hands dude comes back and blows it up trying to kill a bunch of heros at once.
But Peter, other than being able to use the powers of those he is close to, he hasn't proven to be that neat. I would think he would emerge so that he can actually use those powers he got from being near the others and beat up Sylar at some point. If he had a Rogue type setup, where when he was around the others lost their power that would be different, and a copycat, but still not sure what his deal is.
Once the invisible man teaches Peter a thing or two maybe he comes back and is no longer the boom threat but still what is his purpose?
The split personality lady really doesn't serve much of a purpose, other than her and her hubby had a kid who has powers also, but other than that she is strong and nasty - with a nice walk. Does she just prove that breeding the powers is possible?
The cop was ok but he's kind of a bumbling idiot that can't seem to figure out how to prove he can read minds very well. I would think that would be a no brainer. He's not my favorite fella but it would be fun to read thoughts. hehehe
Claire's safe, she's cool, virtually indesctrucable and has some purpose we don't know about yet.
Her dad provides the good yet semi-evil fella and organizer of the team. He's the black helicopter guy that fits in the conspiracy theory. He could be a good guy just helping people to realize and control their powers.
Isaac is needed to continue to paint and give people an idea of what to do, unless Peter takes up that chore....
Hiro is just super. I do like what they said about him not saving the waitress and his powers. FLYING MAN!! swoosh, keep it down would you, *lowers hand* swooosh. hahaha
Flying man, good but he needs an attitude change. He can fly away real fast but a bullet would stop him....
Well, just some ramblings. I think it will be the split personality or the politician.
