Uchiha Itachi - Just for the fact he went to all that trouble to protect his brother. And he wiped out the ENITRE Uchiha clan. That takes some skill.
Namikaze Minato - He was one bad ass motherlicker. Flying Thunder God = WIN!
Tsunade - I just like her character and determination. And the fact her chest measures 106cm
BUT level with Tsunade is Zetsu. That guy kinda freaks me out. But in a good way xd
