Goku Black SSW JUS

Goku Black (ゴクウブラック Gokū Burakku), also known as Zamasu (ザマス Zamasu), though usually referred to as Black, is an alternate incarnation of Zamasu and a former North Kai and Supreme Kai apprentice serving his former master Gowasu from the unaltered main timeline within Universe 10. He serves as the main antagonist of the “Future” Trunks Saga of Dragon Ball Super.

Black visited Universe 6, went to the Super Dragon Balls from the unaltered main timeline within that universe, summoned Super Shenron from said timeline, wished to switch bodies with Goku from the unaltered main timeline within Universe 7, and Super Shenron granted Goku Black’s wish. Goku Black sought to destroy all mortals alongside Future Zamasu, an alternate counterpart of him.[3]
