Chapter 54 of "Dragon Ball Super" will be revealing that Zamasu killed his mentor Gowasu to acquire the green earring from and control future Goku's body. It can be recalled in the last episode that Son Goku and the aspiring Kaioshin fought each other, with the latter realizing a human like Goku can be as powerful as a God of Destruction.
Several predictions were taken from this event as it was also revealed last episode that Zamasu despises humans for having lack of discipline by repeatedly committing mistakes. The new character was also surprised how powerful Goku was when they were fighting each other in battle. Some fans are guessing Zamasu may have envied Goku's power and tried to find a way to get hold of him.
Although the episode title for the upcoming installment is "Inheritor of Saiayan Blood: Trunks Resolve," one big revelation about the origin of Black Goku and how he is related to Zamasu may be finally told. Rumor has it that Zamasu will be killing his mentor Gowasu, in order to acquire the green earing and time ring to take control of Future Goku's body, Dragon Ball Z exclusives shared.
The post added the theory explains why Zamasu is seen wearing only one earring. This is because the other green earring is worn by Black Goku which Zamasu uses to control Goku's alter ego.
The official synopsis for episode 54 discusses that Zamasu and Gowasu will be using the time rings to observe the activities happening at planet Babari. They will be using the time rings to warp several years in the future. The prediction that Zamasu will be killing Gowasa may transpire between these events.
Meanwhile, Trunks will be surprised in the huge gap between his and Goku's power which will put Vegeta in disappointment. The hint from the upcoming episode were commented by several Reddit users in a discussion thread for "Dragon Ball Super." Majority shares how happy they are with Vegeta's slow transition from a heartless Saiayan to a responsible father to Trunks.
