I started to watch the series again a while ago and I noticed that Krillin and Piccolo had that multiform technique.Maybe this is not possible to make in the game, but I just suggested.But there`s one more thing.Vegeta used Kienzan in episode 26 to cut gohans tail.Maybe you could add that, because Vegeta doesn`t have so much moves before transforming.He did use Kienzan only once, but so did he use Gallit gun.
