I wonder if Peter got all the powers that Sylar had or just the one that he was manifesting at the time.

He will always have his enemies powers; he just has to realize it.

Just that. He was waltzing around invisible for a few minutes without even realizing it when he first met Claude. Once he realizes he has a power, then he has to learn to consciously control it.

Right. So if he doesn't know Sylar has super-hearing or fabulous memory, I think he wouldn't even know how to access it. At least right now, when he's still learning.

Is it possible that the only power Peter could/did get from Sylar is the ability to figure out how things work? I mean, Sylar's powers weren't natural. He essentially got them by picking people's brains apart and figuring out how to re-wire his own to access or mimic those abilities.

I don't remember if we've seen Peter use a power that Sylar acquired that couldn't be explained as having some other origin. If Peter only acquires Sylar's mechanical ability, that might be difficult for him to figure out.

I don't think Peter's been around anyone else whose power would explain using telekinesis against Sylar and stopping Claude's lead pipe free-for-all. I can maybe see him being limited to powers currently active at the moment of mimicry.

In terms of limitation on Peter's power: the whole "exploding man" thing could be that limitation if the writers want. If Peter overuses his powers, Peter goes boom.

I'd agree, except I don't think he ever saw Claire's healing power in action before he picked that up. Nor Ted's, for that matter, unless you count the prophetic dream, which I do.

Funny thing, that. Telekinesis is the only one of Sylar's powers we've seen Peter use, and, while we know it doesn't come naturally to him, it was the only power the OWI said they could find a genetic trace of when they were experimenting on him.

So, I wonder if it's perhaps the only thing Peter's gotten from Sylar.

To me, it's obvious that one of the things that will never be clear from canon is how, exactly, Peter's powers work. Some powers he doesn't see, and still uses without conscious thought, like Claude's or Claire's. Others he sees in action and makes an effort to utilize them, like Nathan's or Niki's. (Hello, alliteration, old friend.) Some he may never be aware of, others he might spend a lifetime trying to perfect, like Hiro's. It's obviously pretty complex, and I think part of the reason it drives me crazy is that I inevitably compare it to Sylar's mastery of powers, which arises in an entirely different way. But they can't really be compared, and I think the truth about Peter's power is that it is ambiguous that the writers can manipulate it in all sorts of ways to suit the situation they want.

In terms of limitation on Peter's power: the whole "exploding man" thing could be that limitation if the writers want. If Peter overuses his powers, Peter goes boom.

Indeed. Which makes me ask--do we all, generally, believe Peter's still alive? I ask, because they essentially wrote it into the story without ever expressing it in words. If Sylar, in the first reality, was responsible for the explosion and survived it, because he had acquired both Ted and Claire's powers, and if Peter has acquired both Ted and Claire's powers, and Sylar and Peter are set up as counterweights to each other, then surely Peter will survive. Of course, I'll believe it when I see the IMDB sheet on the shooting of the first episode for next season; but for speculation, it seems like they wrote themselves into a logic hole, until what Gar says above holds true.

I believe Peter is alive. The only question for me is: will he have a scar or not?

I am not sure if Sylar is alive. I really hope he is dead, but I'm thinking he may not be.

It might be interesting if the writers had set it up that he went boom because he was confronted with too many powers in his midst at once. Not unlike when he acquired Matt's and Ted's powers.

But I don't think that's the direction that the writers wanted to go in.
