D is one of my favorite characters, but Dantes asernal of weapons, superspeed (he's not as nearly as fast as Dante though), superstrength (D has that also), and transformation is to much for D to keep up with. Both of them have superhealing, and if Dante uses Guns D will just have his talking hand eat them.
Both are good swordsman so I think that they would go at it for hours just slicing each other unless Dante uses his other powers.
D vs. Dante (without his long range weapons) 6/10, D vs. Dante with his longe range weapons 8/10, and D vs. Dante with every thing hes got 10/10.
Thanks for making this thread Cordera, it's the best I've seen in the video game vs. for a while.
