Editing Fused Zamasu (section)

===Manga===
After Vegeta defeats Black and Goku overwhelms Future Zamasu, Black reminds his counterpart of their trump card. They use the Potara Earrings to fuse into Fused Zamasu. Immediately after the fusion, Fused Zamasu launches a swift attack on Super Saiyan God Vegeta and Goku, incapacitating them both. When they confront him in their Super Saiyan Blue forms individually, they find themselves unable to match his power. During Goku's fight with him, Goku manages to blast a hole through Fused Zamasu, but thanks to his immortality, Fused Zamasu regenerates quickly, rejoicing that his immortal nature remains intact even after the fusion.

Realizing their only hope is to fuse, Goku and Vegeta use the Potara earrings to become Vegito. Transformed into Super Saiyan Blue, Vegito asserts that Fused Zamasu is not a true god but a mortal like himself, pointing out that since Fused Zamasu never officially became a Supreme Kai, their fusion will only last an hour. Fused Zamasu angrily curses Gowasu for never informing him about the time limit of the fusion.

The battle begins, and Vegito quickly gains the upper hand, even slicing off Fused Zamasu's hands so swiftly that Zamasu doesn't notice initially. In retaliation, Fused Zamasu creates numerous Katchin cubes and hurls them at Vegito. As Vegito prepares his Final Kamehameha to finish off Fused Zamasu, the fusion unexpectedly ends, and Goku and Vegeta are hit by the Katchin cubes, sending them crashing to the ground.

Taking advantage, Fused Zamasu knocks Vegeta away and then torments Goku through numerous portals. Vegeta intervenes to save Goku, but Zamasu turns his fury on Vegeta, beating him savagely. Before Zamasu can kill Vegeta, Goku reveals his Perfected Super Saiyan Blue form and engages Zamasu on equal footing. They clash fiercely, with Zamasu unleashing a barrage of punches through portals and Goku countering when he finds openings. Zamasu then uses his Holy Wrath, but Goku manages to deflect it after a struggle and hurls Zamasu into a building. Emerging from the debris, Zamasu taunts Goku, claiming his overconfidence is his downfall and vows to defeat him. With only 20 minutes left before his fusion expires, Zamasu escalates his attacks, threatening to destroy the galaxy by amplifying his power.

When Goku attempts to erase Zamasu with Hakai, Zamasu opens a portal and uses Future Mai as a shield, forcing Goku to halt his attack. As the fusion time nears its end, instead of defusing, Fused Zamasu's immortality causes him to transform into a grotesque half-Goku Black, half-Future Zamasu state. Seizing the moment, Future Trunks steps in and slices him in half.

after Future Trunks slices the half-defused Fused Zamasu in half, Goku Black and Future Zamasu seem to separate. However, as Future Trunks stabs Goku Black, Black stands back up, blasts Trunks, and pulls the sword from his body, shattering it. Both Goku Black and Future Zamasu then individually transform back into Fused Zamasu. They begin to assault Goku, attempting to kill him, but Vegeta, enraged and powered up as Super Saiyan Blue, intervenes. He rescues Goku and unleashes a Gamma Burst Flash on the two Fused Zamases, blowing them apart. Each piece of their fragmented forms regenerates into more Fused Zamases, creating an army.

As this horde of Fused Zamases advances on the Dragon Team, Goku and Vegeta urge Trunks, Mai, Gowasu, and Shin to flee. Zamasu reveals that he now possesses a Time Machine from the Supreme Kai of Universe 12, allowing him to pursue them to any point in time. Searching for a Senzu Bean, Goku instead finds the button to summon Future Zeno. When Future Zeno arrives, the army of Fused Zamases is paralyzed with fear. Goku explains the situation, and Future Zeno deems them annoying, deciding to destroy them along with the entire universe. The Dragon Team escapes in the Time Machine as the army of Fused Zamases attempts to flee, but they are swiftly erased along with the timeline. As he is being erased, Zamasu laments that his plan should not end this way.

As in the anime, Whis travels to an alternate timeline to warn that timeline's Beerus about Zamasu's intentions, preventing any harm to gods and mortals from Zamasu in that timeline.
