I assumed the death of Megaman is Capcom's way of giving the finger to Inafune having left them.
who the fuck wanted vergil, the ryu to dante's ken? or nemesis when we have wesker? if you MUST add further stupid dmc/re characters, capcom, give us lady or uh, well, fuck the boring-ass re cast.
If I remember right, Vergil came pretty high in that poll Capcom did for DLC characters. Not as high as Mega Man X, mind you, but even Capcom has to have some standards.
Vergil is a really good character. In DMC3 SE his combat is completely different than Dante and his moveset is sick. It makes a lot of sense for him to be in the game along with Dante. Though yeah it should have been Lady instead of Trish; no one cares about Trish. Then you could have the DMC3 team.
Nemesis is lolz, but oh well. I guess they don't want any more members of stars beyond Chris, hence why Jill was transformed into a stupid wetsuit kicker; so not much else, though I think Tyrant would've been more badass than Nemesis. Barry would have been great but yeah.
Honestly UMvC3 should have added support characters like MvC1 so they could throw in all these characters who aren't really worthy enough for a full fighting game character build, but it's fun seeing them hop in and shout something and attack.
