1- Orochimaru, in a creepy kinda way
2- Kakashi, intelligent and strong, plus the mask drives the ladies crazy. And that speech when he battled the 7 swordsmen gave me goose gumps
3- Sasuke, hate him or love him but he got style
4- Sage Mode Naruto, with the coat ( movie 5 ). KB Naruto leaves me indifferent, too unnatural
But the ninja turtles are gods among men when it comes to coolness so it's unfair for them to compete -_-
