Dante from DMC.
Quote from Moozooh: " Oh yeah, Dante. As I said before, everything in this show is about Dante and the process of him being cool. He's so cool he transcends the meaning of the word "cool", like the epitome of coolness never seen since the cool came to cool town. He acts cool, he dresses cool, he eats only cool food (pizza, strawberry sundae, beer, nothing else), he has cool overpowered weapons, and even his name is cool. "
gosh... so many badass charachters out there... normally I would say Kamina or Zarak Kenpachi but I felt like going with a female charachter so it shall be:
Chidori Kaname (Full Metal Panic!)
She has one-shotted the top military freak multiple times without paying too much attention, I mean, cmon, that BADASS!
Kenpachi Zaraki, Jin Kariya, And Itachi Uchiha
Kenny for the same reasons that a few people already mentioned
Jin Cuz he's not only the leader of the bount, but his doll is the most powerful
And Itachi for obvious reasons
