The title says it all. Give what you know about this guy. Heres what I got, (it isn't much)
-his recovery is the biggest difference i have seen, and I'm sure most people know about that, but if you don't after using his up b, G&W comes back down slowly on a parachute. You can cancel that into his down a, which seems to be beefed up but I'm not sure.
Yep thats all I got, but someone has to start it. Discuss!
