What the hell is the point of SSB2 for anime-canon Goku?
SS2 is just doubling the power of SS1. It takes x50 to x100. SSBKK can already do that except ramp it up to SSBKKX20. SSB2 makes no bloody sense for Goku and in the context of the anime Goku's SSBKK20 would make Vegeta's SSB2 look like shit.
In the anime continuity SSB2 Vegeta is literally 10 times weaker than SSBKK20 Goku.
