Dragon Ball Super

Season 4: Future Trunks Saga

Episode 15: Zamasu's Ambition - "Human 0 Plan" is Revealed

Future Zamasu reveals himself to be Zamasu from Future Trunks' alternate timeline. Goku fights Goku Black and Future Zamasu, but he proves to be powerless against the two. Shortly after, Goku is incapacitated. Future Trunks rushes to Goku's help. Future Zamasu reveals that he used the Super Dragon Balls to wish for immortality. With Goku recovered, Future Trunks and Vegeta decide to join the fray. Future Zamasu tells Goku that in order to obtain his new body, he had to kill Goku's family, Chi-Chi and Goten, who stood in his way. Enraged, Goku takes on both of the villains. He is initially able to hold his own, but he is soon overpowered and knocked out. With Goku defeated, Future Trunks and Vegeta are backed into a corner. Future Zamasu holds Future Trunks and his constant time-traveling responsible for thwarting his plan to eradicate all mortals. This infuriates Future Trunks, who explodes and transforms into an immensely powerful new form of Super Saiyan.
