31 Aug. - "Dragon Ball Super" episodes 57 and 58 will see Goku, Future Trunks and Vegeta go head to head against Goku Black and Zamasu. According to Parent Herald, the heroes may be in for more trouble as there are speculations Goku Black and Zamasu may fusion together to become an even more powerful being.
It was previously rumored that Goku Black and Zamasu may be one and the same but this was proven wrong in episode 56 when Zamasu descended from the skies and revealed his real target has always been Goku. Zamasu is speculated to be very powerful, even more powerful than Goku Black.
Goku Black had already proven to be a difficult enemy, particularly when he transformed into Super Saiyan Rose. The combination that the two might make when they fusion together could lead to the death of one of the heroes. Fans speculate that Beerus, Vegeta or even Future Trunks may be killed off soon.
A preview for the episodes from Jump Magazine (via Yibada) reveal that Future Trunks would also have to step up his game and fight alongside Goku. This will be due to the fact that his father, Vegeta, won't be able to push forward with the fight since Goku Black had significantly injured him already.
As noted in a report from Attack of the Fanboy, episode 57 is titled "The Birth of the Invincible God Zamasu" and this may hint that Zamasu is going to fight Goku and his allies. This is where the speculations of Vegeta or Beerus' death has sparked from.
Episode 58 is titled "The Secret of Black and Zamasu" and this episode will likely reveal the connection between the two characters or the revelation that they can perform a fusion together. Unfortunately, no preview description has yet been revealed for the episode to further prove this point.
Episode 57 will air on Sept. 4 while episode 58 airs on Sept. 11.
