Synopsis: Goku puts all of his power into his Kamehameha and is able to pierce through Fusion Zamasu's Holy Wrath, once again stopping him from destroying the Earth. In the wake of the explosion, Goku is tired, but Fusion Zamasu's face and right arm appear to have been damaged, as the skin on the right side of his face has turned purple and seems to be melting. Goku overpowers Fusion Zamasu using his Kaioken technique and knocks him out temporarily with a kick to the head, but his use of the Kaioken drains all of his energy and he collapses. Fusion Zamasu regains consciousness and powers up, but he still does not heal; instead, his right arm bulks up and turns the same purple color and consistency as his damaged face. Vegeta wonders why Fusion Zamasu isn't healing, and Gowasu explains that, while Future Zamasu's body was immortal, Goku Black's was not. This means that Fusion Zamasu is only half-immortal, which is where his weakness lies. Goku decides that the only way they can win is for him and Vegeta to fuse using the Potara earrings as well. Vegeta initially refuses, until Gowasu explains that, for non-Kaioshins, the earrings' fusion actually only lasts an hour. Goku and Vegeta don the Supreme Kai's Potaras and fuse, becoming Vegito. Vegito powers up to Super Saiyan Blue and begins fighting Fusion Zamasu, quickly gaining the advantage. However, Fusion Zamasu's body continues to mutate strangely, powering up even more. Gowasu explains that Zamasu's mutation is a result of his anger manifesting in physical form. Meanwhile, Bulma and Mai finish repairing the time machine. Mai gives Future Trunks his broken sword, which inspires him to keep fighting; he uses his energy to restore the sword. Vegito and Fusion Zamasu continue fighting; Vegito is winning, until his fusion abruptly wears off early due to the massive amounts of energy that he was using during the fight. Fusion Zamasu then begins to pummel Goku and Vegeta, until Future Trunks arrives to help. Future Trunks unknowingly begins gathering energy from all living things on the Earth, creating a massive Spirit Bomb, and then absorbs it. With this new power, Future Trunks overwhelms Fusion Zamasu, runs him through with his sword, and cuts him in half, finally obliterating him.
