- This article is about the Zamasu from the future timeline. For other incarnations of , see Zamasu (disambiguation).
"The world is beautiful. But the ugliness of mortals soils its beauty. Therefore, we will destroy all mortals, and reclaim the beautiful world! [...] And now, we will destroy the Earthlings, who possess the knowledge to transcend time and who violently repeat their wars without end... The most repugnant lifeforms in the universe."
Future Zamasu (未来のザマス Mirai no Zamasu) was an alternate timeline counterpart of the Zamasu from Future Trunks' timeline. He is the secondary antagonist of the "Future" Trunks Saga. He was the former Supreme Kai apprentice of Universe 10, who became a Supreme Kai. This version of Zamasu was an ally to Goku Black (his past self from the original present timeline) and the two were the only "gods" left in that timeline. He along with Black worked together to wipe out all Mortals with the Zero Mortals Plan.
Future Zamasu bears an identical appearance to his counterpart. He is fairly tall and lean in build with pale green skin, gray irises, and a tall white Mohawk that curves forward to hang over the left side of his face. He wears a slim violet long-sleeve shirt, baggy blue pants, white boots, a dark grey Supreme Kai vest with yellow trimming, and a pale blue sash folded over his abdomen. Unlike his alternate timeline counterpart, he also possesses dark lines around his eyes and wears a green Potara earring on his left ear, given to him by Goku Black, as opposed to a normal orange earring on each ear.
After meeting Black, this version of Zamasu has truly fallen into the depths of evil, speaking of all "mere mortals" as inferior to him. Like his other counterpart Black, he has a sadistic goal of ridding the entire universe of mortals, believing them to be the source of all evil, and he refers to a world without them as a "utopia". While battling Goku and Future Trunks, he constantly speaks about how mortals misuse their "god-given wisdom" for their own personal gain. Despite looking down on mortals as arrogant and insignificant, he is not so confident to overly underestimate his opponents. After seeing Future Trunks perform the Evil Containment Wave on him to nearly seal him away, Future Zamasu openly admitted that their opponents were a true danger to his and Black's plans. Zamasu is also shown to have compassion but is usually directed to Goku Black. Future Zamasu shows extreme care and concern to Goku Black when he is being beaten and pushed back by his opponent, intentionally taking a blow that would normally severely injure or kill him (albeit he can afford to be reckless due to his immortality). This indicates that like his present counterpart and Goku Black, he is a pure hearted individual and just man driven to extremes by his negative opinion of mortals and sees Black as a kindred spirit (and possibly his only friend) as they both share the same goals.
Despite essentially being the same as his counterpart, Future Zamasu has two key character traits that differ from Black. As he never met Goku before teaming up with Black, he never developed an obsession/hatred of Goku. He therefore wished for immortality with the Super Dragon Balls instead of wishing to switch bodies with Goku. However, like his counterparts, he considers killing Goku as something only he should do. Also, he is fully confident in his strength coupled by his immortality, reveling in and referring to it as befitting him. This is a stark contrast to Black who scoffs at immortality and desires greater strength through fighting.
In the manga, Future Zamasu was also shown to be fully aware of Future Zen-Oh's existence and expresses concern about the possibility of him finding out regarding their plans and the ramifications of this. His relationship with Goku Black also differs from the anime in which their partnership is mostly based on pragmatism as opposed to the mutual kinship that they shared in the anime. Future Zamasu looks down on his counterpart for discarding his divine body for power, while Goku implied that Black merely saw Future Zamasu as a pawn. This differing relationship even saw both of them briefly turning against each other when they were losing to Goku and Vegeta.
Future Zamasu existed in Future Trunks' timeline, he was once a Supreme Kai apprentice training under the Supreme Kai, Future Gowasu. For unknown reasons, Zamasu always held a grudge against all mortals in which Gowasu hoped Zamasu will eventually get over someday.
One day, when serving Future Gowasu tea, he found his master killed under the hands of a mysterious man. The stranger then reveals himself to be Zamasu, from another timeline. He had come here looking for a timeline and universe without a God of Destruction, as Supreme Kais are not allowed to lay a finger on the planets. His search through all realities had eventually brought him to Future Zamasu's world where Universe 7's Destroyer, Future Beerus was deceased. Zamasu offers Future Zamasu a new opportunity to begin the "justice" the world deserves, in which Future Zamasu agrees to. The two then gathered the Super Dragon Balls and wished for immortality for Future Zamasu then destroying the Super Dragon Balls so no one could revert their wishes.
With no one standing in their way, Zamasu and Future Zamasu then initiated their plan: to kill "unnecessary" mortals in order to bring "justice" and to create a "utopia" in the future timeline, as well as any other timeline with it. After killing all of the Supreme Kais, and thus by extension the Gods of Destruction, Zamasu unleashed his wrath on countless planets, killing as many mortals as possible while Future Zamasu stood back, watching their plan unfold.
Dragon Ball Super
"Future" Trunks Saga
Main article: "Future" Trunks Saga
In the manga, while Goku Black wiped out the mortals of Future Trunks' timeline, Future Zamasu used the Time Ring in order to explore all five of the currently existing parallel timelines, and found that there were no major obstacles to their plan. With the Earth's population brought to near extinction, Future Trunks traveled to an alternate past world and returned with aid in Goku and Vegeta.
In the anime only first trip to the future As Goku and Goku Black began engaging in a heated battle, Zamasu appeared next to Black, reminding Black of his promise to allow him to kill Goku. He then attacks Goku at the same time with Black, forcing Trunks to jump in and even up the fight. During the fight, Trunks is fighting evenly with him as a Super Saiyan 2, but when Trunks stabs him in the stomach with his sword, he instantly heals his wound. Zamasu also emerges unscratched from Future Trunks' Final Flash, revealing his body is immortal. Goku regroups with Future Trunks as Goku Black charges a Super Black Kamehameha, with Zamasu grabbing them and holding them in place to prevent them from escaping. Goku and Trunks are defeated by the attack, and Zamasu remained unharmed due to his immortality. With Black, Zamasu prepares to finish off the two Saiyans, but they are interrupted by Vegeta, who woke up and intercepted their attack but fell back unconscious immediately after. In the confusion of the attack, Goku and Trunks have disappeared, so Future Zamasu and Black prepared to finish off Vegeta, but they are forced to fall back when members of the Resistance fire tear gas at them. The two then spot the time machine with the beaten Trunks, Vegeta, and Goku inside, and try to intercept it, but are too late. Zamasu exclaims they will return eventually, and when they do they will meet their end.
Both Future Zamasu and Black are next seen at the cabin they are living in, patiently waiting for Goku and his friends to return. Black is ready to kill Goku once and for all but Zamasu says that he shouldn't kill Goku right away or else Black won't get any stronger than he already is. He then offers Black the chance to become immortal, but Black refuses, saying he is satisfied with the power he has now.
In the anime's second trip Future Zamasu and Black soon sensed the trio had returned and followed suit on their location. They then met Goku, Vegeta, and Trunks and immediately started trading blows once more. Goku then tells them that they knew their plan, in which Future Zamasu was a bit shocked, but delighted asking them if they really knew it. He then tells him the full plan in which Black replies is incorrect, claiming to be another version of Zamasu in Goku's body.
While Future Zamasu and Goku Black fight and constantly defeat the Saiyans, they tell the true story of their past, how Goku Black assumed Goku's body, killed him along with Chi-Chi and Goten, and traveled to the future and killed Gowasu, causing Future Zamasu to reveal his true nature to him and become partners with him, and how he used the Super Dragon Balls to become immortal, then destroying them. Future Zamasu is knocked back by an angry Goku upon telling this story, with Present Zamasu soon defeating him. They later mock Trunks, as he was one of the reasons they did this in the first place which enraged the latter and tries to attack on his own. Black managed to grab Trunks and fires a blast through his stomach, knocking him down, while Future Zamasu stops Vegeta from interfering. They later notice Future Trunks assume a never-before-seen Super Saiyan form after explaining their "Zero Mortals Plan".
Future Trunks with this form fights with Black, with Future Zamasu and Yajirobe surprised at how much he had improved with the form. The two seemed evenly matched, which prompted Future Zamasu to step in help Black against Trunks. However, every attack they try, even the combined Energy Ball, were endured and countered by Trunks in his form. Trunks holds the two off while the others escape in the Time Machine. Black replies that it is okay, since they will come back later and resumes the fight with Trunks.
In the manga events proceed differently, as instead of being the second trip to the future it is the first trip. Future Zamasu appears to save Goku Black when he is taken down by Vegeta, and then proceeds to heal him, giving him a near death power up. While the Z Fighters are surprised by Future Zamasu's appearance, he is brushed off by Goku and Vegeta as just being a small fry. After Goku Black faces Vegeta again and is healed once more he becomes Super Saiyan Rosé. As Vegeta and Black prepare to face each other once more, Vegeta tells Goku to deal with Zamasu, as he will not be able to beat Black if he keeps getting healed, Goku requests Future Zamasu fight him and he obliges, Goku becomes a Super Saiyan Blue and manages to easily knock down Future Zamasu with a single blow, and then when Zamasu attempts to hit Goku with numerous objects he easily reflects a sharpened one back at him, piercing him. Goku then powers down to Super Saiyan and says that it's not too late and they can surrender and undo their plans with the Dragon Balls, but Zamasu reveals his immortality, and the fact that he destroyed all of the Dragon Balls, he then holds Goku still with telekinesis - stating that while he is powerless compared to the Saiyans his divine powers and immortality allow him to fight back and he takes down Goku. At the same time Black manages to gain the advantage over Vegeta and knocks him down, however Future Trunks suddenly uses the Solar Flare to blind the two and they escape. Future Zamasu says that they will just have to wait for them to come back, but Black finds Mai's ki signature and teleports to her, however they find a trap waiting for him, and Future Trunks plunges his sword through Future Zamasu's back, taking him out of the fight.
In the manga, Goku Black and Future Zamasu go back to their cabin after the fight. They discuss on what Black saw while Future Zamasu is worried that the Future Zen-Oh will find out what they are doing to the multiverses. Black scoffs at the notion and they both decide to terminate the rest of the humans. They then begin their mission, killing any human they can find, almost completing the Zero Mortals Plan as a whole.
In the anime, when the fighting resumes in the forest outside of the cabin Black and Zamasu have been staying at, Future Trunks reveals that he has found a weakness with Zamasu and Black's strategy, by throwing a powerful attack at Black Zamasu would throw himself in front of it to block it and would be forced to regenerate himself due to the damage thus leaving Black actually vulnerable to the real attack. Using this new strategy Trunks was in fact able to momentarily knock out and defeat Goku Black. However before Trunks could attempt to destroy Future Zamasu's body Black re-enters the battle and impales Trunks through the spine. Soon after, Black and Future Zamasu notice the Time Machine back in their timeline, indicating that Goku, Vegeta and Bulma have returned once more. They approach to the group, destroying the time machine, proclaiming that this timeline will be their grave, only for Vegeta to correct their claim, telling them that it would be theirs. However, Vegeta and Goku zone out for a little bit, arguing that their "grave" is destroyed and actually don't know what to do. They then resume their conversation and begin the fight. With Goku deciding to fight Future Zamasu once more. However, they are interrupted by Black's former master and Universe 7's Supreme Kai, Shin, from his timeline. Gowasu berates on their actions, calling them "horrible" and "immoral". Black responds to the question that they are talking about, telling them they believe that they are doing all of their actions for a greater cause. Future Zamasu and Black proceed to try to kill the Supreme Kais but are saved by Goku and Vegeta. Goku and Future Zamasu soon continue their fight, with Goku overwhelming Future Zamasu blow by blow, but to no avail, due to his immortality.
After Black created multiple regenerative clones through a slash from his scythe, Zamasu began heading towards where Trunks, Mai and Bulma were. As this was going on, Goku's usage of Instant Transmission was blocked through the rift, preventing him and Vegeta from chasing after Zamasu. After Zamasu reached his destination, he is soon confronted by Bulma, who tries to flirt with him to buy her son enough time to master the Evil Containment Wave, but to no avail, as Zamasu angrily grabbed her through the collar and knocked her out. Upon seeing this, Trunks is quickly reminded of Future Bulma's death and successfully unleashed the Mafuba on Zamasu, placing him in the jar. Bulma soon regains consciousness orders Mai to seal the jar with the talisman, but to their shock the talisman was forgotten at Master Roshi's house. The three of them tried to hold the jar to prevent Zamasu from escaping, but to no avail as Zamasu escapes barely breathing. Upon sensing that Zamasu's ki is getting weaker, Black uses Instant Transmission, teleporting himself to Zamasu. Black asks Zamasu what happened, with the latter warning Black that mortals mustn't be underestimated and that their plan could be crushed if they let their guard down. After finding that the time is ripe, Zamasu put his Potara earring on his right ear, and the two of them fused together to create Fused Zamasu. Due to Black being a mortal, the fused Zamasu is mutated since it is a fusion of an immortal and a mortal. After fighting Goku, Vegeta, Vegito, being sliced in half by Trunks, and finally being erased from existence along with the universe, by Future Zen-Oh, the fused Zamasu is defeated, and ultimately, Future Zamasu is too.
In the manga, Future Zamasu arrives to Black's location after killing any Earthling he could find. He easily dispatches Shin when he was about to attack Black as he speaks to the Z-Fighters. Later, seeing Goku Black in danger and Goku and Vegeta in the future once more, Zamasu assists him in fighting Vegeta. However, Goku intervenes and thus Future Zamasu and Goku fight once more. Goku immediately overwhelms Future Zamasu and seals him off with the Evil Containment Wave. However, Goku has taken a hostess bar catalog from Master Roshi instead of the actual seal, resulting in Future Zamasu's release. Goku then transforms into Super Saiyan God in order to keep him from interfering. Almost down for the count, Future Zamasu yells at Black they argue about their own interferences with the Zero Mortals Plan. Black then suggests they should "become complete". As a result, the two of them create Fused Zamasu, much to Goku and Vegeta's disbelief.
In the manga, Fused Zamasu defuses after his hour is up, however the immortality of Future Zamasu will not allow them to seperate and he and Black are stuck in a deformed half fused state. Future Trunks proceeds to cut them in half, however this allows the two to reform individually due to both retaining the immortality. Future Zamasu transforms into Fused Zamasu after Goku Black took down Future Trunks behind Goku and slowly approach the latter. As the two Fused Zamasu's are preparing to kill Goku, Super Saiyan Blue Vegeta rescues him and then fires his ultimate attack: the Gamma Burst Flash - blowing the two Fused Zamasu's into pieces, which then reform into many Zamasu's.
In the anime, after this, Whis goes to the future before Future Beerus' death and preemptively warns him about Future Zamasu, creating a new timeline free of Future Zamasu's tyranny.
Other Dragon Ball stories
Dragon Ball Xenoverse 2
Main article: Dragon Ball Xenoverse 2
During the events of Future Trunks Saga, Goku Black and Future Zamasu somehow manage to change history. The Supreme Kai of Time and Old Kai then tell the Future Warrior to help Future Trunks to go back in time with the Time Machine while Future Warrior helps Goku to fight Goku Black. Before Goku Black gets pulled by the time and space distortion and destroys the Time Machine, he notices something strange with his Time Ring while fighting the Future Warrior. After another change in history, the two Future Warriors go to Future Trunks' timeline to help Vegeta to fight Super Saiyan Rosé Goku Black. During the fight, Goku Black notices his Time Ring acting up again, knowing there was something familiar about the Future Warriors.
After returning to the Time Nest, Goku Black asks Future Zamasu how should they deal with the Time Patrol, telling him that it will require some patience. Goku Black and Future Zamasu then fight against the Future Warrior and Super Saiyan Anger Future Trunks. After everything returning to normal, Goku Black and Future Zamasu manage to make another change in history during their final battle against the Z-Fighters by bringing Turles, Broly, Janemba, Slug and Cooler due to the Time Rift Goku Black has created with his scythe. Black and Zamasu then had no choice but to fuse into Fused Zamasu.
Like his alternate counterpart, Future Zamasu is a fighting prodigy, and in between the time gap from his first encounter with Black and the Zero Mortals Plan conflict, this Zamasu's fighting abilities increased significantly.
Future Zamasu's immortality gives him a massive edge in combat, allowing him to use himself as a living shield to protect Goku Black and allowing Goku Black to use his powers without worry of hurting Zamasu. However, due to his immortality, his fighting style does not focus on the defensive unless when it concerns Black. This allows his opponents to catch him off guard at times, such as two occasions when Trunks stabbed him or blasted him away.
In the anime, Future Zamasu now possesses enough power to face Super Saiyan Blue Goku in battle, and Super Saiyan 2 Trunks soon after. He can even hold down both opponents simultaneously long enough for Goku Black to strike them down. However, as his opponents got more powerful in future encounters, Future Zamasu was no match for Goku, Vegeta or Future Trunks. If not for his immortality, he would have been easily killed on various occasions by his opponents. This was shown when he was momentarily dispatched by a rage-empowered Super Saiyan Blue Goku with a single backhand, when he was previously able to hold his own against the Saiyan. Future Zamasu was also easily blasted away by Super Saiyan Rage Trunks, and only gained the upper hand after Trunks had exhausted himself fighting Black.
In the manga Goku becomes Super Saiyan Blue to fight Future Zamasu as he is expecting him to be strong, but after hitting him once notes that Future Zamasu is nothing compared to Goku Black, and power-wise will be easy to defeat. While Future Zamasu is shown to be able hold his own, capable of tracking some of Super Saiyan Blue Goku's movements and dodge a punch from him, he was no match for Goku otherwise. He was easily knocked to the ground with a single blow from the Saiyan. Goku then powered down to an ordinary Super Saiyan upon realizing that Future Zamasu was not that powerful, however he was quickly paralysed and overwhelmed by Future Zamasu - with Future Zamasu noting to Super Saiyan Goku that while he was stronger than him, his godly techniques would allow him to hold his own. Later, Future Zamasu was however taken down by a quick attack from the rage-empowered Future Trunks - who plunged his sword through him. When he was faced with fighting Future Zamasu alone, Future Trunks noted that he should be at least be able to stall him, and prepares to fight him with just his base form. Future Zamasu proved to be much stronger than Shin, easily besting the Supreme Kai. When Goku fights him again later he transforms into a Super Saiyan God - noting the form would be more than enough to defeat Future Zamasu (even though Goku had lost a huge amount of stamina from using the Evil Containment Wave - to the point that he claimed he could not turn Super Saiyan Blue), and the only thing he had to worry about was getting paralyzed. Goku then proceeds to easily beat him down and notes that even Future Trunks is much stronger than Future Zamasu is.
Upon transforming into the form of Fused Zamasu, Future Zamasu possessed all of the power that the Potara Fused Zamasu possessed, including possessing the Super Saiyan Rosé form.
Techniques and special abilities
- Immortality – The ability to remain unchanged by the passage of time, unable to die, and simply live forever. Obtained using the Super Dragon Balls. Due to his apparent immortality, Future Zamasu is only moderately unfazed by any injury, no matter how grievous. He is also apparently unaffected by energy attacks, as he took the full brunt of Future Trunks' Final Flash and Goku Black's Black Kamehameha without a scratch. Moreover, he was even saved from being erased by Beerus also thanks to this ability. However he can still be defeated by sealing him away using sealing techniques like the Evil Containment Wave. He is also susceptible to being Erase from existence by Zen-Oh.

- Healing - As a Kai, Future Zamasu possess the ability to rejuvenate anyone and restore them to full health instantly, even if they are on the brink of death. In the manga, during his team-up with Goku Black, they would repeatedly allow the latter to be grievously injured before Zamasu would heal him, thereby allowing Black's Saiyan body to become strengthened from the experience. This eventually allowed Black to fully master Goku's stolen body and unlock Super Saiyan Rosé.

Zamasu is implied to possess a pure heart by Gowasu's comments on how well-balanced Zamasu was at brewing tea. One of Zamasu's passive Skills in Dragon Ball Fusions.
- Supervillain Mode - By shaving off some of his life (which is not a problem for him thanks to his immortality) Future Zamasu can access the Supervillain Mode power up in Xenoverse 2 as part of the Super Pack 4 DLC. While using this power up his eyes glow pink, and he gains a sinister white and black aura. He can use this Dark Magic-based power up despite being a Shinjin who possessing godly ki.
- Darkness Mixer - A ki and stamina charging technique in which the user produces a dark aura that also damages nearby enemies. One of Supervillain Mode Future Zamasu's Super Skills in Xenoverse 2 as part of the Super Pack 4 DLC.
In the manga, due to Goku Black and Future Zamasu being the same person, they fused on a cellular level, and are unable to properly defuse, and left in a semi-fused state. After Future Trunks attempts to kill them by slicing them in half the immortality is shown to have stayed with both of them and they reform fully, with the immortality then allowing them to re-mold themselves into Fused Zamasu individually. Future Zamasu appears behind Goku and then transforms himself into Fused Zamasu.
Fused Zamasu Main article: Fused Zamasu
An extremely powerful permanent fusion born between the union of Future Zamasu and Goku Black by the Potara earrings. Due to Black's body, able to power up constantly when in near death or while fighting, and Future Zamasu's immortality. He was created by Goku Black and Future Zamasu in order to turn the tides around against Goku, Vegeta, and Future Trunks, who all have gotten far stronger than the Zamases could handle. Even when holding back, Fused Zamasu was able to take on Future Trunks, Vegeta, and Goku all at once and separately in their strongest forms and later held his own against Vegito when Zamasu was going all out.
Due to the fusses being one and the same, neither one of the fusses are dominant, and Fused Zamasu's attributes are evenly distributed and blended perfectly. Because of this, he does not have the desire to be too flamboyant like Goku Black and does not let the obsession of Goku stop him from getting the job done. Additionally, due to being a mix of two of the same people, although at the same time contrasting in abilities, Fused Zamasu can experience mutations that can make him stronger.
However, along with this perfectly mixed body came many weaknesses. In the anime, this fusion became an unstable fusion because of Future Zamasu's immortality mixing with Black's mortal body, causing him to slowly fall apart. In the manga, the fusion is perfect, but can only remain active for an hour at a time because an official Supreme Kai is not involved in the fusion. But in the end, all of the problems Fused Zamasu faces are only temporary, due to Goku Black's Saiyan Power as Fused Zamasu managed to adapt to all of his weaknesses.
- Potara - After killing Gowasu, Black took his former master's Potara earrings, allowing him to use the full capacities of a Supreme Kai. Upon meeting his future counterpart, Black gave him the right earring.
- Time Ring - Due his godly ki as a Kai and wearing an earring of a Supreme Kai, Future Zamasu is able to wield a Time Ring, which allows him to travel through time and even alternate realities. He only wields this in the manga, while in the anime his partner Goku Black is the one who possess the Time Ring. In the manga, Future Zamasu also keeps the entire box of Time Rings on his person.
Video game appearances
"Zamas became a Supreme Kai after Goku Black defeated Gowas. Aims to destroy all humans with his "Zero Mortal Plan." "
— Dragon Ball Fusions character profile
The description in Zamasu's character profile in Dragon Ball Fusions implies that he represents his future incarnation, though his appearance is that of Present Zamasu. However it should be noted that it is not uncommon for video games to use a single character to represent incarnations from different timelines such as is the case with Future Android 17 and Future Android 18 (who are often represented by Android 17 and 18 in various video games).
Future Zamasu also appears in Dragon Ball Xenoverse 2 as part of the 3rd DLC pack, where he is simply refered to as "Zamasu". He incorporates the use of the Aura Slide in his normal combos. Additionally, because of his immortal body, Zamasu never receives any bruises or cuts on his model, even after reaching critical health.
