Scariest Naruto character of all time, is Dosu. Even if he threw a punch at you and missed, he'd get you with his stupid soundwave thing, oh so cheap. Also he's insane, so you don't really know what that @$$ is gonna do. With people like Gaara and Orochimaru you know to avoid them, Dosu would prolly be walking with you in the alley then just snap and throw a punch and you'd be bleeding from the ear and pukin your guts out. Also Hinata is kinda iffy, she is so quiet, shes gonna snap pretty soon too...
