Right, some great quesitons there Conivar and Weasel soup.
My 22'227 cents.
Future Hero (5 years) and future peter did have an issue, and wasn't it something to do with Hero giving peter the big scar? So maybe when Hero goes for revenge on Adam and Adam is with Peter he maybe has to attack peter.
I reckon Peter will change time with Adam and avert the huge virus deaths, these things always go that way, even with X-men the futuristic episodes were always harking back to getting the present right. That's kind of ironic that time travel focuses on getting the present right when we're basically putting off saving the planet 'cause it'll all be alright in the end' type syndrome.
The haitian's powers only seem to work on mental or mind powers, like Hero's Parkkans, Eve's and Candice(did I imagine that?) So not sure Peter would be invincible.
Interesting question though, how did peter get the scar in the future, if he can heal why didn't it heal. that leaves the option that in that future that Hero didn't change Peter didn't save the cheerleader and so didn't ab sorb clare's healing ability. But then also would never have come into contact with Adam. Unless peter's scars from before the power would not be healed?
Anyways, glad to see I've some Heros plotline buddies, throw them at me people
