Any anime character that doesn't have giant hair. . .which eliminates almost all of them. But Gaara is cool, he's the deliverer for NinjaSubs (don't ask, there are only two other users on AG who will get this.)
I have watched all Naruto episodes (like 400 or something) and one episode on Full Metal Alchemist (pretty boring) and the opening of Bleach... Omg that one sucked. So I have to say ............. Kankuro or Gaara. Yeah, it was some time since I last saw Naruto.
