Obviously a lot of people believe that either Peter or Sylar are the most powerful out of all of the heroes revealed so far and that is indeed warrented. Peter can absorb any power he comes into contact with without ever having to kill them like Sylar. Both of them now have numerous powers and can pretty much stand up to anyone (except for each other). However, there can be considered any other hero as the most powerful. What about Micah or Molly? They are kids and their powers, such as themselves, are maturing with age and they could potentially become more powerful than either Peter or Sylar. Just throwing out my ideas. Who is the most powerful in your book?
