Back to the Future – Goku Black's Identity Is Revealed!!.While Beerus is confident that the death of the present Zamasu has solved the crisis, Future Trunks expresses some skepticism and needs to return to his timeline to see for himself. Future Trunks proceeds to explain to Trunks the nature of alternate timelines while expressing some hope that Beerus's god status might actually averted Black's existence as he is joined by Goku, Vegeta, and Bulma. Once they arrive, the group find nothing has changed as the Saiyans and Bulma regroup with the Resistance as Future Trunks uses a senzu bean to heal Mai. The Saiyans then sense Zamasu and Goku Black approaching and face them, Goku calling Black out as a clone created by Zamasu using the Super Dragon Balls. But Black reveals himself to be Zamasu, explaining that he used the Super Dragon Balls to switch bodies with another version of Goku before killing him.
