He's been announced for a while, there's already a lot of in-game footage of him.
For his st. HP, he just shoots a handgun like Cable from MvC2. It goes fullscreen too. Since it's a normal, you can cancel it into his air/ground teleports, which you can cross up with. So it's basically a free approach into mix ups, pretty cool. He also has an air super where he throws a missile at you. Yeah.
