Dragon Ball Super Ep 58 English Sub Reveals Zamasu used Super Dragon Balls to summon Super Shenron and become immortal and create Goku Black. Next week there will NOT be Dragon Ball Super Episode 59 English Sub but Episode 59 preview is available now. So, I think Whis is half correct. I think Black Goku (Goku Black) is actually Zamasu from different timeline. Zamasu from present time line wants to kill Gowasu, and Beerus might be killing off Zamasu in two weeks so get ready for a rematch between Goku vs Zamasu full fight!
