DMC 2 Dante. He seems to be the most serious and the most powerful. He also won this poll by a landslide. XD --- Newer isn't always better. And I shall keep Dante's Force Edge polished and sharp till he comes back.
As crappy of a game as DMC2 was, this version of Dante wins by a landslide. This Dante is a lot older and more experienced than all previous incarnations, said to have surpassed Sparda himself in power, and that's saying something.
