Probably Kabuto, Think about it.
It entirely depends on whats driving them yknow?Yes, but being brave simply means having no fear, no matter whether it's against any odds or not. While overcoming your fears is exactly what you would expect of a strong willed person. Of course when someone OP rushes to fight it's not that impressive, just like someone rushing in without thinking. But most OP ninja are brave, too - especially the good guys who don't get "blinded" by their power.
Aw man, I don't even know why I'm nitpicking, I guess me being a Virgo kicked in :| I'm sorry
Btw, what would you say about those who go fearlessly against someone beyond their level on someone's order, as in out of loyalty?

You can be lead to do something for all the wrong reasons like Sasuke taking on the 5 Kage to hunt down Danzo out of bloodlust for example.
Being brave is returning to your destroyed village and fighting the leader of the Akatsuki. Because you have to.
Or attacking your reanimated sensei even though you're a kind and gentle person. Because there's no other choice.
Minato, he didn't care Madara was a Jubi's Jinchuriki even stronger than Obito's. He attacked him with no fear
I wouldn't include the last point .Her and Sakura are pretty brave
Sakura did sort of the same
Stood up to Gaara, while defenseless
Stood up to the sound nin
Sacrificed her self for Chiyo
Ran up to Naruto in his feral form.
Was willing to sacrifice her feeling for the leaf, the whole Sasuke thing
I wouldn't include the last point .
That was the moment which made me dislike Sakura even more .
Like seriously ? Leave the village for a boy who hardly gave a shit about her .
Kisame is one of best shinobi nv has produced!!I respect Kisame. His view were bad, but anyone who's willing to die for what they believe in is brave in my book.
Kisame never really backed down from anyone either.
Because he is immortal and he has nothing to lose.
