There is a lot of hype for Rocket Raccoon, a Marvel character that was unexpected and hope he would continue a certain tradition. I'm not sure if that tradition is back, but this raccoon definitely has his own bag of tricks to be not the joke character some feared he would be. The burrowing concept for instance is somewhat new for a fighting game like this, but he has projectiles and traps that can OTG. Being a small character means he'll probably won't do that much damage, but if you want to style on dudes, give Rocket Raccoon a shot on your main team.
Frank West from the Dead Rising series returns to the fighting game world after his debut in Tatsunoko vs. Capcom. For those thinking he will be the same from that game, think again as he has some differences. Taking snapshots with his camera increase some level for something (perhaps more damage?). He doesn't have a level 3 hyper move, but his three level 1s have their uses. His cart hyper is OTG (the other OTG move is a sweep, which is probably crouch H), a rush-like combination hyper that can go through projectiles if timed right, and an anti-air giant swing where he puts on the Servbot head on you.
There's more what these two characters are capable of than my descriptions as I will update this post with the match videos as soon as they get up on the interwebs. Maybe I'll just the man himself Seth Killian demo these guys off for the IGN folks.
