MODOK has great rushdown.
Not much love for Super Skrull here.
Team Triple Fisting for UMVC3: Iron Fist, Spencer, Super Skrull.
Of my team, the only character I have that is pure rushdown is Felicia. I run Taskmaster and Dante in front, and I play them in a rushdown style a lot, but I think it’s important that your first and second characters are able to respond to multiple situations. Would suck to stick to nothing but rushdown characters while dealing with Hulk or some other heavy hitter who is about one thousand times easier to deal with by zoning.
I know from some local experience that Super Skrull and X-23 can be beasts in rushdown too, when the user knows what the hell they are doing. Really, anyone who can ‘wavedash’ with enough speed to make people go ‘what the hell?’ is going to be capable of good rushdown, and that’s a large chunk of the cast.
