Okay, since you asked. Though I'd prefer if you didn't call me Barbie, that doll's smile creeps me out.
*cough cough* DMC4 Dante, most definitely.
DMC3 Dante is cute, and Vergil in pair with him, but considering at this point I am 10 years older they feel more appropriate as baby brother cute. This includes Nero as well.
DMC/anime Dante has his merits, but it's that unshaven look that won me over in the end.
Credo's goatee gives him negative points. Maybe if it weren't pointy...
I wonder if anyone out there will actually consider Agnus...
