Unless Dante actually has timestop in which case he has a slight chance.
Dante stomps on Mihawk. Dante can slice dimensions in DMC4. Mihawk wont be able to even kill him, Nero tried and failed. And since you didn't put any restrictions, he has access to all the devil arms and all of his styles and his devil form, plus Yamato. Mihawk loses badly here.
@supernova7005: I dont think Mihawk has better durability or strength feats than Dante. If Dante goes Dreadnought, nothing Mihawk can muster will hurt him. And he can time stop via the BoT, but he didn't use it in DMC4. If all else fails, he can just spam rockets and all types of demonic ammunition via Pandora. Plus, all the feats Mihawk pulled off, Dante could do it as well, IMO.
@supernova7005: Oh yeah, remember the Blitz calc.
And pretty sure OP has a mach 20+ calc at least for the mid tires. Know that many were bitching about it because the top tires are so much faster but because they don't have and solid feats for them they have to go with the mid tire calc of mach 20-something+.
