Someone modded Goku into Super Smash Bros. for Wii U and it's everything we needed
Proof Goku needs to join the Smash roster
No, Goku isn't in Super Smash Bros. for Wii U like he ought to be, but that doesn't mean that the community won't make that happen. With the combined effort of multiple modders, Goku has joined the Smash Bros. roster.
Of course, it's not really Goku. It's a Ryu skin (doesn't make it any less awesome).
Super Mega Buster, with the help of KTH, ShadowLuigi, and Nanobuds helped make the mod possible, now all we need is for Nintendo to recognize the glory that is Goku and make him available on the NX port of Smash Bros..
