Err, sorry if I seemed offensive. ^_^; Megaman Voulnutt is my favorite character in TvC and quite possibly my second favorite character in the entire Megaman Meta series after classic Mega himself. I just got a bit defensive, that is all. Your opinion is fine with me.It doesn't matter if he was a good or bad character for competitive play.
He was just plain boring. Both the visual design and his moveset-design.
(Just my personal opinion, bro)
Zero on the other hand, was fun as hell to play as.
As for Zero, I don't know if I could ever use him in fighting games. He has the second lowest HP in the game (tied with Roll) and while he has a lot of combo potential his attack power is sorely lacking. You have to be fast and furious with him and while I can easily play that way with him in X4-X6 and Zero1-4, having to play that frantically while using input commands for specials seems a bit too much for me. I have him on my team in pretty much every match I play in U/MvC 3 and he's generally the first one to die. I just can't get the hang of him. He's just not worth it to me, but that's just me. To each their own as they say.
