One of the most impressive villains introduced in Dragon Ball Super is Zamasu.
However, after meeting Goku, Zamasu’s attitude and personality changed markedly in a bad direction.
When the threat of Zamasu (known as Black Goku after he took over Goku’s body in another timeline) appeared across multiple timelines in Universe 7, the God of Destruction Beerus quickly solved the problem.
The key to Zamasu’s survival in the future lies in how he can travel with the time ring to different timelines in Dragon Ball’s multiverse.
The incident with Black Goku may have been one of the first major instances of time travel and its consequences that Beerus had to face.
Another element of future Zamasu’s existence is that the rules of time travel once existed that Beerus did not pay attention to.
Besides, perhaps because Beerus is always overconfident, in fact he may not be the one who possesses supreme power as shown to humans.
