We have sene battles but not proper full one on one fights. We need to see them back to their normal selves (with peter and full abilities) and have a proper battle with them.
Hmmm... Honestly? Sylar. I think he has better control - and remember I am Peter fan, too, at this bit - more brains. He wouldn't play fair, and he'd be... well, kick ass.
I think Arthur may be equivalent to Sylar, Sylar slightly stronger now. Arthur could have pushed the bullet away but he didn't the GN explained why. If Arthur serious had a fight with Sylar, it would of been close
Ok thats none of my concern but if we're talking graphic imagine the spunk flyin around the room and decorating the walls no need for dulux cos in bed we know the colours that do go.
