How will things play out if Peter absorbs Ando's power. Will he be able to amplify the powers he has on his own?

That would be freakin crazy.

Oh crap. Peter would be unstoppable. I was thinking that if Ando was the supercharge Peter, Peter could just absorb all the powers within all of New York in one go. Oh great, don't make Peter more powerful! That's dangerous territory!

That would. We need to know more about Ando's power first, though...

on the other hand, ando doing the same to sylar would probably be just as intense, maybe even moreso

OKAY! having a scrub's JD-type fantasy.
Ando supercharges Peter AND Sylar and they have a mega battle

Only problem: Ando would be dead.

Or, Peter could be overwhelmed. All his powers would be juiced up at once and he might liquify NY with his radioactive-ness

Remember what Daphne said about she wanted to run, and got that ability, Matt was worried about what people think and got his ability.

Ando is now the PERFECT sidekick. His power amplifies the Heroes power.
I wonder if it also works in reverse, limiting their power?

Also, I know in a version of the future it seems like Ando kills Hiro, but maybe Hiro gets a power again, and the reaction of him falling down is similar to Matt's reaction when Ando activated his power on him.
