Goku needs more attacks he has
Spirit Bomb (Which goes when he is SSJ)
And Solar Flare which is rubbish.
They are his only special moves so i don't know what you want to give him but please give him something.
Actually Goku is one of the characters with the smallest number of moves and attacks. List them out. I can only think of
and his Generic attacks
I may have missed a couple there (excluding those I wont list from the movies), but not many. Goku is not a very diverse character. For the most part he uses melee to destroy his enemies, and he only uses energy attacks in drastic situations. The characters with the most attacks on the series would probably be Cell, followed by Piccolo, and then Gotenks. I say Gotenks last because 70% of his attacks aren't even really attacks, just fancy ways of saying "kick" and "punch." Goku shouldn't have the most attacks... he's already a balanced character, and even these next two attacks being added into beta 1.1 might unbalance that.
Remember guys, Goku doesn't have to be the best at everything. Just because he was nearly invincible on the show doesn't mean he needs to be in ESF.
