No prizes for guessing, this angered Goku but he still failed to defeat Black Goku. In fact, Black Goku goes as far as claiming that he killed Gohan, Goku and Chi-Chi in different timeline. "Dragon Ball Super" episode 61 also revealed that they went and wrecked different timelines. In other words, with Dragon Balls destroyed, no one in the universe would be able to match their power. This was done to ensure that no one can make a wish anymore. Using the Dragon Balls, Zamasu and Black Goku wished for immortality for Zamasu and wished for the Dragon Balls to be damaged. With Gowasu eliminated, he could use the Time Ring without any restrictions. There's a hearsay that only Supreme Kais are able to use Time Rings, which is probably why Zamasu is so bent on killing Gowasu.
Anything that happens to him in the past doesn't affect him, which is exactly the reason why he is still alive and the time is still unchanged, AttackOfTheFanboy reported. Thanks to the time ring that Zamasu possess, Beerus' attack did not cause any sort of damage to him. He just destroyed his own body and switched it with Goku. As far as Black Goku is concerned, he is just another Zamasu from a different timeline that has stolen the body of Goku. The Future Zamasu is Zamasu hailing from Trunk's timeline. What is the true identity of Future Zamasu who is standing next to Black Goku? Fret not! Here's what you need to know. Last week, it was divulged that Black Goku is actually Zamasu who has abducted the body of Goku.
Looks like "DBS" fans are in for a good surprise this week, as Black and Zamasu shed more light on their plan.
