"My form is justice! My form is the world! Revere me. Praise me. This noble and beautiful... immortal and most powerful god... Zamasu!"
— Fusion Zamasu upon his birth in Revere Him! Praise Him! Fusion Zamasu's Explosive Birth!!

Fusion Zamasu, usually just referred to as Zamasu (ザマス), is a fusion born of the union between Goku Black (Zamasu in Goku's body) and Future Zamasu through the Potara earrings. He is the final antagonist of "Future" Trunks Saga


The fusion heavily resembles Zamasu, yet supplemented with various traits of Goku Black, including the latter's height and build. He possesses Zamasu's green skin, gray irises, and white hair; however, his face has more of Goku Black's jawline. He has 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 green Potara earrings on both ears and Supreme Kai's clothing that is nearly identical to Zamasu's, but with Goku Black's color-scheme. It consists of a black form-fitting shirt with long sleeves and a turtle neck, baggy black pants, white boots, grey robes with a red lining and a dark red sash that is tucked in fully. He also wears a Time Ring on his right index finger.


Retaining the arrogance and self-entitlement of Goku Black and Future Zamasu, this fusion believes himself to be the embodiment of justice. Reveling in his power, Zamasu openly declared himself the supreme god upon his emergence, repeatedly and consistently vocalizing his divine brilliance and absolute authority. His ego is displayed by how he refuses to even defend himself against Goku and Vegeta, his tendency to hover high over the battlefield to "look down" on everyone both figuratively and literally, and his use of "divine" terms (such as "holy", "judgement", and "absolution") to name his special techniques.

However, beneath his calm exterior, Fusion Zamasu is just as unstable as his components, if not moreso; according to Gowasu, this is the result of Zamasu's obsession with the contradiction between gods and mortals. He immediately flies into an overwhelming fury when Trunks and Vegeta briefly overpower him in their beam struggle, despite suffering no damage from the deflected attack, and his rage only grows when Goku manages to actually harm him. By the time he engages Vegito, Fusion Zamasu is reduced to enraged screaming and furious declarations of godhood, ironically becoming just as destructive and violent as the mortals he wishes to exterminate.

Fusion Zamasu believing his "justice" is for the greater good of the universe.

Interestingly, Fusion Zamasu is well aware of his own hypocrisy in taking on mortal elements by using Goku Black as a fusee. He views this as a necessary sacrifice to truly create his new world; by using Goku's body as part of his being, he intends to never forget the "sins" of mortals. He also states that his actions are for the greater good of the universe, even crying at its thought, and believed his tears would purify the world.


Dragon Ball Super

"Future" Trunks Saga

Main article: "Future" Trunks Saga Future Trunks uses the Evil Containment Wave on Future Zamasu after Bulma distracts him to seal him away in a vase with Future Mai closing it with the lid. Unfortunately, Goku forgot to take the talisman made by Master Roshi, allowing Zamasu to break free. However, he was left weakened by the effort of escaping; moreover, he was deeply shocked that his enemies had discovered a means of actually neutralizing him despite his immortality. When Goku Black arrived, having sensed Zamasu's ki decreasing, the latter informed his counterpart that they could no longer afford to underestimate the mortals.

Fusion Zamasu creates his Ring of Light

Declaring that they would display the true power of gods, Zamasu and Black stand beside each other in the sky, with the former taking his Potara earring from his left ear and attaching it to his right ear. This initiated an explosive Potara Fusion between the two villains, creating Fusion Zamasu. Upon his birth, he declares his new form to be the embodiment of justice and the world. He orders everyone to revere and praise him, calling himself "The Supreme God".

Fusion Zamasu proceeded to unleash a devastating assault, causing heavy damage to his surroundings and putting Goku, Vegeta, and Future Trunks on the defensive. However, he flew into a rage when Vegeta and Future Trunks managed to push back his Holy Wrath with a double Galick Gun, striking them down near-instantly with Lightning of Absolution. He then turned his attention to Goku, throwing another Holy Wrath to meet the Saiyan's God Kamehameha. Goku's attack overpowers Fusion Zamasu's and Goku attacks him further, despite him losing the ability to use his arms, but Fusion Zamasu crushes his left foot. Goku retaliates by combining his Super Saiyan Blue form with Kaio-ken and knocks Fusion Zamasu down, but Goku runs out of energy and falls. Fusion Zamasu grows angrier and angrier, powering up and taking on a mutated state as his right arm grows in size.

Zamasu's Light of Justice.

After Goku and Vegeta used the Potara Earrings to fuse into Vegito, Zamasu still declared that their form would be unable to defeat a god, but Vegito proved to be able to easily deflect Zamasu's Holy Wrath attack with one hand, and they began battling and their power appeared to be equal. Vegito managed to land some damage in Fusion Zamasu, due to Black's mortal body causing Fusion Zamasu's immortality to have flaws. Despite this, Fusion Zamasu managed to survive Vegeto's Final Kamehameha, also showing to have suffered little damage from the attack, and Vegeto's attack caused their fusion to run out early, and Zamasu easily defeated both of them. Before having the chance to finish them off, Future Trunks stepped in and blocked Zamasu's attack with his ki sword. The two then battle in a sword fight. Trunks was able to slash Zamasu's body, but his body quickly healed and he angrily reminded Trunks he was still immortal before swatting him away. Pinning Trunks down, Zamasu openly declares Trunks' weakness and taunts him about where he would seek for help next, the past or the future. However Trunks boldly claiming that he was not ashamed of weakness before telling him that mortals help each other. Trunks' pride in his humanity allows him to unknowingly draw the energy of everyone alive on Earth. Trunks realizes what the energy is, and Goku and Vegeta give their remaining energy to Trunks, increasing the power of his sword. Zamasu tells Trunks the power he gathers from mortals will not be enough to defeat a god and tries to strike Trunks down, but fails. Trunks take the ki of the people of Earth into his own power and transforms his ki longsword into a larger greatsword. Trunks and Zamasu continue to fight, and Zamasu continues to berate mortals, but Trunks says that it was not about mortals and gods, but about not losing to Zamasu because he only believes in himself. Zamasu swings at Trunks, but Trunks breaks Zamasu's sword.

Fusion Zamasu is defeated by Future Trunks.

Then, Trunks pierced his body with his sword. Zamasu felt the imense energy and asked how that was possible, and asked Trunks if he dared to go against a god's "justice". Declaring his "justice" to be meaningless to everyone, Trunks sliced Fusion Zamasu's body in half, obliterating his body in the process, finally putting an end to both Zamasu and Black's reign of terror.


Manga and Anime

Fusion Zamasu fends off Goku and Vegeta at once

Possessing the combined power of Goku Black and Future Zamasu amplified, this fusion is shown to be able to fend off the combined efforts of Super Saiyan Blue Goku, Super Saiyan Blue Vegeta and Super Trunks. Gowasu notes that Black and Zamasu's fusion has expanded their combined power to no visible end, which is consistent with previous uses of Potara Fusion. In addition, Fusion Zamasu possesses Future Zamasu's immortality and Goku Black's limitless potential growth, making him a near-perfect entity. He is also able to singlehandedly overwhelm Goku and Vegeta, nearly crushing their hands simultaneously, and also nearly killing Super Saiyan Blue Vegeta in one blast. However, when he engages in a beam struggle with both Super Trunks and Super Saiyan Blue Vegeta at the same time, Fusion Zamasu is overwhelmed. Super Saiyan Blue Goku at full power also manages to hold his own against him and defeat him in a later beam struggle and successfully engage him in combat, breaking his wall of light. Against Super Saiyan Blue Vegito, Fusion Zamasu proved able to make the mighty fused foe fight seriously. To which, many of Fusion Zamasu's attacks forced Vegito to dodge, which still caused considerable damage to the area from the sheer force of his blows.

According to Gowasu, Fusion Zamasu's body is unstable due to one fusee being immortal and the other fusee being mortal. This caused Fusion Zamasu's body to fluctuate, creating mutations in his body that multiplied his size and power, but left his body completely unstable and no longer completely immortal, although he did retain a tremendous amount of durability and a potent healing factor. In his mutated form, Fusion Zamasu appears to be on par with Super Saiyan Blue Vegito, as neither fighter was able to land a decisive blow. However, when he gained his Power Stressed form, his speed greatly decreased, and as a result, he was unable to keep up with Vegito's speed and almost met his demise, being gradually overwhelmed until Vegito defused, and Fusion Zamasu was able to defeat Goku and Vegeta with one blow. Ultimately, however, his new instability proved to be his undoing as the damage from his battles slowly accumulated, which ultimately led to his demise at the blade of Future Trunks.

Statements by authors and guidebooks

According to the pre-release summary, he is so powerful that the mere force/pressure of his energy field alone is too intense for Goku and Vegeta to even get near him, let alone attack him; additionally, the trio's ki blasts are erased before they even make contact.

Techniques and special abilities

As a fusion of Future Zamasu and Goku Black, Fusion Zamasu possesses all the techniques and abilities of his fusion components:

  • Flight - Zamasu is capable of flight using his ki.
  • Continuous Energy Bullets - Zamasu can unleash this attack from a single hand.
  • Semi-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. As a result of Goku Black's presence within his being, Fusion Zamasu is not completely immortal; only ageless and with a high tolerance for pain and damage.
    • Regeneration – Zamasu heals any wound he may incur. However, due to the Goku Black part of him still being mortal, it takes him much longer to heal, resulting in his misshaped state.
  • Saiyan Power - Obtained from Goku Black, Zamasu is able to become considerably stronger after recovering from damage he sustains from his enemies.

Zamasu's Wall of Light

  • Ring of Light - Zamasu creates a white ring (that looks like a giant halo) around his body, which acts like a barrier.
    • Wall of Light – Fusion Zamasu emits a powerful purple bird-like structure structure of enormous energy which eliminates all that it touches.[1] This Wall of Light seems to possess a being of its own as it roars when destroyed by Goku and Vegeta.
    • Lightning of Absolution - Fusion Zamasu fires a purple-colored lightning blast from his ring of light, or the body of his Wall of Light.
  • Blades of Judgement - From his halo, Fusion Zamasu fires a barrage of red energy blades that can strike the opponent. If the blades makes contact with the earth, they will burst in a destructive explosion.
  • Holy Wrath - Fusion Zamasu creates a sun-like energy sphere and tosses it at his opponent.
  • Fierce God Slicer - Fusion Zamasu can create a purple blade of ki which emanates from his hand.
  • Pain Squeeze - Fusion Zamasu grabs his opponent (usually by an arm or leg) and by concentrating his ki, squeezes the body part he grabbed to induce great pain.
  • Explosive Wave - Zamasu shines red and bursts out ki from all over his body, starting from his right eye.

The bodiless Zamasu fires a Chou Makouhou

  • Chou Makouhou - A powerful red mouth energy wave used by the bodiless Zamasu, when firing it his eyes turn red as well.
    • Chou Makouhou Barrage - An attack where all the heads of the bodiless Zamasu fire Chou Makouhou at the same time. Fusion Zamasu used this to decimate the surface of the future timeline's Earth, killing almost all of the survivors.

Forms and transformations

Super Saiyan Rosé

Main article: Super Saiyan Rosé

Fusion Zamasu's Super Saiyan Rosé state

As the Potara Fusion of Black and Future Zamasu was performed while the former was in still in his Super Saiyan Rosé state, Fusion Zamasu's base state is a constant Super Saiyan Rosé. Because of which, the resulting fusion probably cannot enter a normal form nor power down. While normally this would cause a significant strain on the fusion's body and shorten his lifespan, the immortality gained from Future Zamasu, eliminates this problem to an extent.

Light of Justice

Main article: Light of Justice

Fusion Zamasu after using the Light of Justice

By calling upon the "Light of Justice", Fusion Zamasu becomes larger and more muscular. His aura changes from colorful white to that of Black's as Super Saiyan Rosé. Despite the great increase in power, the flawed nature of Fusion Zamasu's body comes with a side-effect of his body mutating, resulting in parts of his body becoming an oversized and purple gooey substance. It also caused his right eye to gain a purple iris and yellow sclera. This is because of the nature of the fusion, with Future Zamasu's immortal body merging with Black's mortal body, the balance between Fusion Zamasu's body and soul becomes unbalanced. According to Gowasu (who simply refers to this state as an "ugly form"), another reason for this was Zamasu's twisted, conflicted soul manifesting its nature on the outside.

Power Stressed

Main article: Power Stressed

The bulked-up Zamasu stands before Vegito

As a result of his great anger at losing to Vegito, combined with the forced mutation from his Light of Justice, Fusion Zamasu bulks himself up, amplifying his power even further at the cost of his speed. Ultimately, this was his downfall as he was unable to keep up with Vegito and a humanity-empowered Super Trunks.


Main article: Non-Corporeal Zamasu

Zamasu's essence spreads across the sky

After Trunks destroyed his body, Fusion Zamasu re-appears, as a bodiless, non-corporeal form, becoming a reality encompassing entity in an attempt to become all things. In this form, the combined might of base Goku, base Vegeta, and Super Trunks can do nothing to him and he's capable of reducing the Earth to a scorched wasteland in seconds, killing the remains of all humanity. In addition, he appears to be spreading rapidly across the universe and even visibly appears in the present timeline through a time distortion, seemingly attempting to break his way into the present. However, he is no match for Future Zen-Oh called in by Goku, who effortlessly erases him out of existence after Zen-Oh deems him "annoying".

  • Fusion Zamasu is the first villain in the franchise to be created by use of Potara Fusion.
  • Unlike Old Kai and Kibito Kai, Fusion Zamasu does not have a singular voice. Instead, his voice consists of two "Zamasu" voices overlapping one another, creating a sort of echo effect. This may be due to the fact that both of his components were technically separate instances of the same being (albeit with one possessing a different person's body).
  • Unlike his fusees, who use the Japanese pronouns 'watashi' (Future Zamasu and formerly Goku Black) and 'ore' (Goku Black at some point after his first fight with Goku) when referring to themselves, Fusion Zamasu uses the pronoun 'waga', which is commonly used to show that a character holds himself in rather high regard and thinks very little of others as a result.
  • Fusion Zamasu is the first main villain that was not defeated by Goku or any other Z-Fighter. He was defeated by Future Zen-Oh as a last ditch effort.
