Fused Zamasu

Fused Zamasu is the result of the Potara fusion between Goku Black, the version of Zamasu who stole Goku’s body, and Future Zamasu, the immortal Supreme Kai apprentice of Universe 10’s future timeline. This fusion was born during the climactic stages of the battle against the two, when their coordinated assaults and overwhelming synergy still failed to crush Future Trunks, Goku, and Vegeta outright. Seeking an ultimate, unbeatable form, the two Zamasus merged, combining Black’s immense Saiyan fighting prowess and capacity for limitless growth with Future Zamasu’s unending immortality.

In his fused state, Zamasu retained all of their divine arrogance and sense of righteous purpose, seeing himself as the supreme god destined to bring about the “Zero Mortals Plan” and create a flawless utopia purged of all mortal life. Unlike many unstable fusions, Fused Zamasu’s mind remained a unified will at first, perfectly blending Black’s sadistic love of battle with Future Zamasu’s calm yet fanatical conviction. His power surged far beyond either component, dwarfing even the might of a Super Saiyan Blue. In this state, he declared himself justice incarnate, believing his existence to be the ultimate expression of divine order and beauty, and freely taunted his enemies while dismantling them with overwhelming, godly ki techniques.

Appearance: The fusion heavily resembles Future Zamasu, yet supplemented with various traits of Goku Black, including Goku Black's height and build. He possesses Future Zamasu's green skin, gray irises, and white hair; however, his face has more of Goku Black's jawline. He has Future Zamasu's eye shape, but with dark lines under the bottom eyelids and somewhat smaller ears. The fusion's hairstyle looks mostly like Goku Black's as Super Saiyan Rosé, but with a long protruding bang over the right side of his face, representing Zamasu's mohawk.

He wears the original present Gowasu's green Potara earrings on both ears and dark grey Supreme Kai vest with red trimming that is nearly identical to Future Zamasu's, but with Goku Black's color-scheme, undershirt and red sash.

Personality: Fused Zamasu embodies the combined arrogance, god-complex, and zealous conviction of both Goku Black and Future Zamasu, magnified by the immense power and perceived perfection of their fusion. He regards himself not merely as a god, but as the absolute and eternal embodiment of justice, the ultimate authority destined to cleanse the cosmos of mortal “imperfection.” Upon his creation, he wasted no time in proclaiming his supremacy, showering the battlefield with proclamations of his divine brilliance and eternal reign. His godly ego is reinforced by his battlefield demeanor—choosing to hover high above his enemies to literally and figuratively look down upon them, refusing to dodge or defend against attacks he deems beneath him, and lacing his techniques with sanctimonious terms such as “holy,” “judgement,” and “absolution” to reinforce his self-proclaimed divinity.

Despite his initial composure, the fusion’s mind is deeply unstable, even more so than either of his components. Gowasu attributes this volatility to Zamasu’s fixation on what he views as the intolerable contradiction between gods and mortals—gods as infallible overseers versus mortals as chaotic and corrupting forces. This contradiction festers within him, feeding both his hatred and his obsessive need to assert control over all existence.

Fused Zamasu is acutely aware of the irony and hypocrisy in his own existence, having willingly incorporated mortal elements by fusing with Goku Black. Rather than deny it, he rationalizes it as a necessary sacrifice—by forever carrying Goku’s mortal body within his divine form, he ensures he will never forget what he sees as the sins of mortals and the failures of the gods. He paints this act as the highest form of divine responsibility, declaring that his tears—shed for what he insists is the greater good—are tears that “purify the world.” His ideals are rooted in a belief that a god without the strength to destroy what he deems evil is worthless, and thus his worth lies entirely in his unmatched power and his willingness to wield it without hesitation.

Abilities: Flight - The ability to fly without the use of ki.

Immortality – The ability to remain unchanged by the passage of time, unable to die, and simply live forever. This power was obtained from Future Zamasu, who wished for it through the Super Dragon Balls.

Regeneration – Fused Zamasu heals any wound he may incur.

Wall of Light – Fused Zamasu emits a powerful purple bird-like structure of enormous energy which eliminates all that it touches.

Black Power Ball - Black can create a golden colored Energy Ball with a core of black energy to attack the opponent. Once he fires it, the attack becomes completely golden with a black outline.

God Split Cut - Black creates a field of purple energy around his right hand, creating a blade powerful enough to bifurcate a much bigger being.

Right after the fusion, Fused Zamasu combines both sources of his power and a halo of light appears behind his back. This is a powerful technique since it allows him to eliminate all attacks toward him as well as strike his opponents by firing multiple purple-colored lightning blasts. This technique also raises the power of Fused Zamasu immensely.

Absolute Lightning - Fused Zamasu fires a purple-colored lightning blast from his ring of light, or the body of his Wall of Light.

Black Kamehameha - Black is shown to be able to use a black-colored version of the Kamehameha.

Illusion Smash - Through his ability to open portals, Fused Zamasu is able to open a portal near himself and near his opponent so he can punch them from a distance.

Holy Wrath - Fused Zamasu creates a sun-like energy sphere that combines Black Power Ball with God Splitter and tosses it at his opponent, expanding it to a large size.

Violent Fierce God Slicer - Fused Zamasu can create a purple blade of ki which emanates from his hand.

Blades of Judgement - From his halo, Fused Zamasu fires a barrage of red energy blades that can strike the opponent. If the blades make contact with the earth, they will burst in a destructive explosion.
