||Zamasu, a Supreme Kai-in-training from Universe 10, takes it upon himself to purge mortals in his misguided effort to protect the multiverse. As part of this plan, he uses the Super Dragon Balls to switch bodies with Goku, using the Saiyan hero's immense power, combined with his own godly abilities, to carry out the genocide of all mortals as the dark savior, "Goku Black". In an effort to surpass and mock the Saiyan warriors, he developed his own transformation, Super Saiyan Rosé, a pink variation of the Super Saiyan God Super Saiyan transformation. (Name trivia: Super Saiyan Rosé could be named in the same convention as other gods, being a pun on Rosé wine.)
In Dragon Ball FighterZ, Goku Black possesses a similar gameplan to that of Super Saiyan Goku, albeit with a larger emphasis on long-ranged attacks and mixups. He can enlist the aid of Future Zamasu to pin opponents down with a unique variant of his Kamehameha.
