i want some explanasion because just pain wont be enough xD oke uhm mine is... difficult would you call him a evil character? idk anyway if he is then mine would be ITACHI: itachi the hunted by sasuke guy from the very beginning turning out to be the protector of his little brother. all his pwnage skills developt with hate in the heart he sacreficed everything for sasuke well thats it
lol, jk seriously though, my favorite evil character of all time would have to be Kimimaro he was the only one who was able to beat and almost kill Gaara back then, his powers are awesome, and he's also my favorite character in the ps2 Naruto game... umm.. i forgot the name but there was a 3 in it..
