As someone who's almost lost eye-sight from staring at DMC4 for long periods of time, and unintentionally studying every in-game character model, I think that DMC4 Dante is indeed bulky...but not gorilla bulky. More like "bear" bulky. If his shoulder width and arm size are any indication, it's clear that he's gained some muscle since DMC1, which I find weird considering how lean he was in that game (yet another thing to add to DMC's ever-growing list of inconsistencies).I didn't care for the design of Dante, not only because of his outfit, but because he's so ridiculously bulky. He's like a gorilla.
What's even more puzzling is how his facial hair and eyebrows are dark, when his hair is clearly white. I understand that the moment I start questioning hair color is when I fall in rank with the circa-2010 DmC haters...but I could never help but wonder.
