Dragon Ball Super Episode 64

Vegeta continues to overpower Goku Black. Future Zamasu attempts to intervene, but Goku cuts him off. Goku Black realizes that Vegeta’s increased power comes from his anger and uses that method to increase his own power. Goku Black distracts Goku and Vegeta by creating many energy duplicates of himself to confuse them, while Future Zamasu goes after Future Trunks, Mai, and Bulma. Bulma attempts to buy time for Future Trunks to prepare the Mafuba by flirting with Future Zamasu. However, he sees through her trick and knocks her out. This angers Future Trunks, who powers up to his new Super Saiyan form and uses the Mafuba on Future Zamasu. The Mafuba works on Future Zamasu, who is sealed within the jar. However, in the present, Kame-Sennin realizes that he forgot to give Goku the paper amulet that would make the seal permanent. As a result, the seal fails and Future Zamasu breaks out of the jar, which weakened him. Goku Black goes to help him, and Goku and Vegeta follow in pursuit. Realizing that they have underestimated their enemies, Goku Black and Future Zamasu use their Potarra Earrings to fuse into a single immensely powerful being known as Fusion Zamasu.
