Editing Fused Zamasu (section)

===Dragon Ball Super: "Future" Trunks Saga===
In the anime, Future Trunks employs the Evil Containment Wave on Future Zamasu, thanks to a distraction by Bulma, to trap him in a vase, which Future Mai seals with a lid. However, because Goku forgot to bring the talisman created by Master Roshi, Zamasu is able to escape. Although he manages to break free, the effort leaves him weakened and shocked that his enemies had found a way to neutralize him despite his immortality. When Goku Black arrives, having sensed a decrease in Zamasu's ki, Zamasu tells his counterpart that they can no longer afford to underestimate the mortals.

Determined to demonstrate the true power of gods, Zamasu and Black float side by side in the sky. Zamasu removes his Potara earring from his left ear and attaches it to his right, initiating a powerful Potara Fusion that births Fused Zamasu. He immediately declares his new form as the embodiment of justice and demands reverence as "The Supreme God."

As he manifests a halo of light, Fused Zamasu extolls his body's abilities and launches a lightning attack at Goku and Vegeta. Vowing to showcase his divine might, he unleashes explosive blades at the Saiyan duo. After they recover, Zamasu asserts that the Project Zero Mortals will be completed and continues his lightning assault, enduring Vegeta's counterattack. To emphasize his power, Zamasu releases a bird-like ki figure that repels the Saiyans and damages them to the point of reverting to their base forms. Looking down on the defeated pair, Zamasu turns his attention to Earth, unleashing his energy to cleanse the planet. However, Goku and Vegeta recover, destroy the bird-like ki technique, and attack Zamasu directly, who blocks their attack and retaliates with more exploding blades.

When Future Trunks intervenes, a brief skirmish ensues, ending with Trunks being knocked to the ground. Zamasu mocks the mortal and attacks with Holy Wrath, which clashes with Trunks' Galick Gun. As Zamasu's attack overpowers Trunks, Vegeta joins his son, and together they launch a combined Galick Gun, pushing Zamasu's attack back but causing minimal damage. Frustrated by their resistance, Zamasu targets Trunks, only to hit Vegeta when he steps in. Goku then confronts Zamasu with a God Kamehameha, clashing with Zamasu's Holy Wrath.

Goku's attack overpowers Zamasu, resulting in an explosion that leaves the right half of Zamasu's face and body badly damaged, oozing a purple substance. Goku follows up with a close-range assault, but Zamasu grabs his leg. Goku enhances his physical attack with Super Saiyan Blue and Kaio-Ken, kicking Zamasu to the ground and destroying the halo. Exhausted, Goku collapses. In a rage, Zamasu calls upon the Light of Divine Justice, augmenting his mutilated arm into a monstrous form.

As Vegeta and Goku fuse into [[Vegito]], Zamasu questions why mortals would imitate the gods, deeming it sinful. Vegito, tired of his monologue, punches him in the face and ascends to Vegito Blue. The two engage in battle, with Vegito initially having the upper hand, mocking Zamasu’s divine power. Angered, Zamasu knocks Vegito to the ground and attempts a finishing blow with his ki blade, but Vegito counters with his own. Vegito points out that Zamasu, fused with Goku's mortal body, is technically also mortal. Zamasu claims this was his intention; by fusing with Goku, who surpassed the gods despite being mortal, he embodies the gods' failures and atones for both mortal sins and divine mistakes.

Zamasu sheds tears, which he believes will purify the world, before powering up and growing larger, his right side becoming more grotesque. The fight resumes, with Vegito taunting Zamasu for failing to keep up with his speed and launching a Final Kamehameha. However, Zamasu emerges unscathed. As Vegito uses up his power, the fusion time limit expires, and he splits back into Goku and Vegeta. Zamasu quickly overpowers them. Before he can deliver a killing blow, Trunks intervenes and blocks his attack.

By now, Zamasu's mind is fully consumed by hatred and insanity. He fights Trunks, mocking his mortal weakness. Trunks, unashamed of his humanity, holds out against Zamasu, unconsciously gathering ki from Earth's inhabitants. Noticing this, Goku and Vegeta contribute their ki as well. With everyone's power channeled into his sword, Trunks charges at Zamasu, who is unable to defend against the enhanced attack and is stabbed. As Zamasu questions Trunks' defiance against his "divine justice," Trunks declares it meaningless and slices Fused Zamasu in half.

After Fused Zamasu is split in half and seemingly destroyed by Trunks, his will survives due to Future Zamasu's immortality. Moments later, a dark energy column erupts from the spot where he vanished, ascending into the sky and splitting into multiple beams before transforming into a vast, cloud-like form. This ominous cloud spreads across the Earth's surface, eventually enveloping it and taking on a sinister appearance, with Zamasu's face imprinted all over and emitting a maniacal laugh. Gowasu explains that Fused Zamasu has discarded his physical form, attempting to merge his essence with the very fabric of the universe to impose his warped version of justice and order.

Despite Goku, Vegeta, and Future Trunks combining their powers to launch a Kamehameha, Galick Gun, and Final Flash, they are unable to harm Infinite Zamasu. Continuing the mission initiated by his previous forms, Infinite Zamasu unleashes destructive energy waves upon Earth, annihilating most survivors and leaving the planet desolate. His influence rapidly spreads across Universe 7 in Future Trunks' timeline and even begins to manifest in the present timeline.

As Trunks and Mai grieve over the loss of their friends, it seems that Zamasu is invincible. However, Goku remembers the device given to him by Zeno and presses the button, summoning Future Zeno. Future Zeno finds Zamasu's presence annoying and declares that the entire world must be erased. Charging his energy, Future Zeno releases a blinding light that obliterates Zamasu along with the entire future timeline. This act ends Zamasu's reign of terror and prevents his plans from reaching their ultimate goal, stopping his attempt to invade the present timeline. Afterward, Whis travels to an alternate timeline to warn Beerus about Zamasu's intentions, preventing the plan from ever being re-created and allowing Future Trunks and Future Mai to live in that timeline after their own world is destroyed.
