The sprite work is just amazing, I really liked it! although I've never played MVC3 and I don't know nothing about Marvel Comics, I must say your char is quite impressive.
If I have I a complaint, is about the hyper bg, it's pretty bad with all that colorloss, it really doesn't blend well with the greatness of your char.
Oh, d,db,b + AB gives super jump.
Dragon Ball Super is about: Lazy plot, kawai eyes, incoherent levels of power and deus-ex machina (all the time).
