1. Minato - his Hokage cloak alone puts him at #1, dat swagger is too much. Plus the blond hair and blue eyes, he just looks perfect.
2. Third Raikage - he's a Superhuman, monstrous tank of a ninja. And he's so jacked it's ridiculous.
3. Gaara - Shippuden Gaara is a real step up from part 1. Such a cool, relaxed demeanour. And his auto sand defence fighting style is so cool. All he has to do is stand there.
4. Tobirama - dat fur though

and the arms always folded thing really suits him.
5. Ay - even though he loses his cool a lot, there is no doubt that he is a badass. I love how he put Sasuke in his place. The guy wears a gold belt like he's some wrestling champion. And instead of walls he prefers to just blast wholes in the war instead.
