Those are usually due to BS writing, plot convenience, or a deux machinima.
But yet people consider that as such.
We are assessing 2 fighters stats, skills, and abilities to see who will win in a hypothetical fight this is not a story written fight where the writer can twist it however he wants but a calculated fight with no strings attached or bullsh*t.
But even so, we still wouldn't know because are we using the game version of the characters or are we doing this cutscene wise? and even so, which Dante are we using here? DMC3? DMC4? And then you also have to remember that stats differ from universe. Old Dante's stats could be nothing to new Dante in his universe. Both beat gods under circumstances, and both have taken wounds that would kill people.
So then DMC Dante will demolish DmC Dante no competition.
Again, if Nero could hold his own against Dante, then New Dante could do a hell of a lot better. Yeah, new Dante would lose, but not before f*ckin' up Old Dante good.
DMC Dante is faster, stronger, has greater durability, is smarter, more skilled in combat, more diversed abilities, and has better weapons.
Dante's actually not that fast. He just as fast reflexes. I don't see him instant transmission like Vergil during cutscenes. Yeah, Old Dante has great durability, but that doesn't mean he can't die. Old Dante isn't even smart. both are just idiots using brute strength and skill. True, but last time I checked, skill isn't always going to win the day. May I refer you back to Neji vs Naruto? That "Diverse ability" differs with every game so there's no exact skill he has. So just because he's got prettier weapons he's better? Plus his weapons also differ so there's no stationary weapons he carries on him besides his shotgun, handguns, and sword.
DMC Dante defeated Demonic Gods who were at full power and even toyed with Argosax (a demon king) before finishing him off quite easily as well.
DMC1 Dante defeated Mundus because he was still sealed and wasn't at full power. And again, what could be considered god in DMC's universe could be childs play in DmC. Plus, Argosax was during when DMC Dante was in DMC2 Dante, which is over-kill.
Dante will probably crush a full powered DmC Mundus.
