Yes, I'm picking Dante. I was playing Marvel vs Capcom 3 with my dad earlier, kicked his ass playing as Dante XD
Stage: Geeze, Dante would fight wherever he wanted. He breaks everything XD
Theme: "Lock and load" epic song right there man xD
Special move: All round, since he's half demon, he's pretty kickass. Abnormally strong, fast, agile, and instant healing (Dude can take a sword to the chest, he'll be fine!)
Dedicated to Aishia, for such a fun challenge .w.
