Dragon Ball Super - Season 4

Goku shows his new farm to Chi-Chi and Goten, tricking Piccolo into a harvesting competition for training until Krillin arrives and accidentally reveals that Vegeta is training with Whis. Goku uses instant transmission to reach Beerus's planet, offering the Destroyer a ball of lettuce while learning that Zeno is not a fighter but has the power to erase entire universes as there had originally been 18 universes instead of the current 12 universes. Meanwhile, in an alternate timeline, Future Trunks is running from a mysterious enemy named Black who is terrorizing his Earth. Trunks meets up with Future Bulma who finally finished preparing the fuel needed for the time machine to make its trip to the past. But Black tracked Trunks to their hideout with Bulma urging her son to leave without her as she is killed soon after. Trunks later meets up with Future Mai, informing her of Bulma's death as they proceed to the ruins of Capsule Corp to reach the time machine. But Black intercepts them en route, seemingly killing Mai when she attempts to distract him so Trunks can reach the time machine. Future Trunks is enraged and looks at Black, revealed to be a Goku look-alike.

Goku Black (ゴクウブラック, Gokū Burakku) taunts Future Trunks for failing to save his loved ones, provoking the youth to assume Super Saiyan form in a losing battle. But Future Trunks distracts Black with an energy attack long enough to reach the Time Capsule and escape 17 years into the past. Meanwhile, in the present timeline, Trunks is studying in class along with the Pilaf Gang, who were allowed to live in Capsule Corp. During recess, Trunks witnesses the Time Capsule arriving with Future Trunks inside. He immediately calls for his mother, who contacts Vegeta and Goku while Trunks and the Pilaf Gang are confused by the stranger having both Trunks's face and name. Bulma asks Trunks to power up in order for Goku to be able to teleport himself and Vegeta to their location, Whis and Beerus joining in to see what's going on. Vegeta asks Goku to get some Senzu beans. Goku goes to Korin's place to get some Senzu beans. Future Trunks regains consciousness, and attacks Goku upon assuming him to be Black.

Goku holds Future Trunks off long enough for Bulma to calm him down, Future Trunks is formally introduced to everyone present while being informed of the events that occurred since the Cell incident. Future Trunks reveals that after he prevented the revival of his timeline's Majin Buu, Goku Black appeared and massacred most of humanity with only him and few remaining people fighting him in a losing battle. Bulma deduces that Future Trunks came back in time to get reinforcements while finding a journal that her future self hid in the Time Capsule, Goku and Vegeta both intrigued while Beerus and Whis are astonished that humans are bold enough to mess with the affairs of time-space. Back in the alternate future, Black realizes Trunks traveled back in time as he uses his ring to open a tear in time to reaches the present as Future Trunks finished his spar with Super Saiyan 3 Goku to determine each other's power.

Goku Black arrives in the past, expressing an interest in fighting Goku and is able to hold his own against his Super Saiyan form while Future Trunks wonders why Goku is holding back. The fight continue until the time distortion caused by the Time Capsule begins to fade, weakening the time tear as Black is being dragged back to the future. But he destroys the Time Machine as his final act in the present, Whis revealing Black used a Time Ring (時の指輪, Toki no yubiwa) that only Supreme Kais possess. But he and Beerus are astonished when Bulma reveals that she kept the other version of Time Machine that Cell used to travel back in time, intending to use her future self's journal to repair it. Just as Black reappears in the future timeline, Future Mai regains consciousness.

While Future Trunks is waiting for Bulma to finish the repairs on the Time Capsule, Goku heads off to King Kai's planet to train after Beerus and Whis refused while both being curious about the sense of familiarity from Goku Black's energy. Future Trunks then notices Mai and recognizes her as the past version of the Mai he knew, revealing how Future Mai was a leader of Earth's resistance movement who died fighting to protect the planet. He also mentions Black's ultimate goal is eliminating everything he considers an inferior being. Meanwhile, excited from facing Goku, Black seeks to fight him again to become more accustomed to his body.

While Bulma and her team are still repairing the Time Machine, Future Trunks finds Piccolo and Krillin mending the damages in the wake of Goku's fight with Goku Black. Future Trunks learns from Piccolo that Gohan had become a scholar and is convinced to properly thank Gohan for his alternate self teaching him to fight. Future Trunks meets Gohan at the university before being invited to Gohan's house for dinner, the experience renewing his resolve to stop Goku Black. Future Trunks returns to the Capsule Corporation, learning that Goku, Beerus, and Whis have left to another universe to investigate the mystery behind Black's energy signature. Almost the end of the episode, a glimpse of a Supreme Kai is shown.

Goku, Beerus, and Whis arrive on the Tenth Universe's World of the Kais (界王神界, Kaiōshin Kai) where they meet the resident Supreme Kai Gowasu (ゴワス) and his apprentice Zamasu (ザマス), who expresses a disdain for mortals. An excited Goku challenges Zamasu to a sparring match, the Kai objects until Gowasu allows it with Beerus advising him to not hold back. Zamasu is baffled at being outmatched against Goku while Beerus and Whis note the Kai's energy being similar to Goku Black's, with Zamasu having no recollection of meeting Goku, and that the Time Rings in Gowasu's possession are accounted for. Goku, Beerus, and Whis return to their universe, unaware their actions only strengthened Zamasu's ideology. On Earth, Krillin introduces Future Trunks to his family, with Android 18 teasing Trunks due to his history with her alternate future self.

While Bulma and her team put the finishing touches to the rebuilt Time Machine, Vegeta decides to test Future Trunks' power to see how strong his son had become and overpowers him in Super Saiyan Blue form. Vegeta is vexed over Future Trunks being content with him and Goku being strong enough to defeat Goku Black, telling his son that Saiyans should continually strive to grow stronger to always prepare for an enemy. On Beerus' planet, Beerus and Whis are about to eat dinner when Zeno contacts them with a request to see Goku. In the Tenth Universe, Gowasu attempts to have Zamasu reconsider his views on mortals by temporary promoting him to Supreme Kai and use a Time Ring to observe the progress of a new race on Planet Babari (惑星ババリ, Wakusei Babari) within a millennia's time.

In the Tenth Universe, Gowasu is unable to change Zamasu's perspective about mortals while his apprentice kills a Babari that attacks them. Gowasu scolds his student and says such behavior goes against his teaching of maintaining the balance between good and evil, Zamasu expresses his view that mortals are evil and their extermination is justice. Back in the Seventh Universe, Whis and Beerus reluctantly heed Zeno's request and summon Goku with instructions to keep quiet about Goku Black and time-traveling. As only Supreme Kais can reach Zeno's palace within minutes, Beerus instructs Whis to let nothing happen to the current Seventh Universe Supreme Kai as Goku learns that a Destroyer can die if their Supreme Kai counterpart is killed. Goku, Whis, and Shin reach Zeno's palace. Zeno says that all he wanted was a friend to play with when he feels like having fun, allowing Goku to leave after he promises to return with a better friend for him to play with. Before Goku leaves, Zeno gives him a button that would summon him. Shortly afterwards, Goku, Beerus, and Whis leave for Earth, where the Time Machine has been repaired. Goku, Vegeta, and Future Trunks arrive into Future Trunks' alternate timeline. As soon as they arrive, Goku is attacked by the Earth's resistance forces who mistook him for Goku Black.

Future Trunks quickly pacifies the resistance fighters by explaining that Goku and Vegeta are allies, reunited with Future Mai as they reach the resistance's new refuge after Goku Black attacked them. Goku spots Future Yajirobe (未来のヤジロベー, Mirai no Yajirobē), who was assumed to have died during the Androids' attack but was saved by a Senzu bean Korin gave him. After beating Goku at Rock-paper-scissors, telling Future Trunks to only observe, Vegeta calls out Black and fights him in Super Saiyan Blue form. But Black's battle with Goku allowed him to fully master his powers as he transforms into a pink-haired form he dubbed Super Saiyan Rosé (超サイヤ人ロゼ, Sūpā Saiya-jin Roze), overpowering Vegeta before critically wounding him with a hand stab. Goku quickly assumes Super Saiyan Blue to fight Black, Vegeta revealing their opponent has an advantage over Goku as well. Just as Black readies a Kamehameha, Zamasu suddenly intervenes and reveals himself as Black's partner while reminding him that he is supposed to kill Goku.

Zamasu states himself and Goku Black as "kindred spirits" desiring an utopia without mortals before attacking Goku, ultimately allowing Black to join the fray as Future Trunks aids Goku. During the battle, Zamasu reveals to have made his body indestructible to all forms of attack while grabbing Goku and Future Trunks so Black can take them out with a Kamehameha. Zamasu and Black decide to finish them off as a badly wounded Vegeta saves Goku and Future Trunks as Future Yajirobe spirits them off a safer location. Before Goku Black and Zamasu are able to finish off Vegeta, Future Mai and the resistance soldiers intervene and rescue Vegeta. Goku and the others return to their timeline using the Time Machine. Future Mai and Future Yajirobe are left behind. Back in the present in the Tenth Universe, the past version of Zamasu sees a recording of the tournament between the Sixth and Seventh Universes and expresses disgust that Goku can harness divine energy. Zamasu also developed an interest in the Super Dragon Balls.

Zamasu travels to Master Zuno's planet to force him into tell him about the Super Dragon Balls. At Capsule Corporation, Bulma nurses Goku, Vegeta, and Future Trunks before Beerus and Whis arrive with Shin, who reveals Zamasu's visit to Zuno. After the deities learn of the group's experience in the future, Whis theorizes that Zamasu used the Super Dragon Balls to create an ally in Goku's form and later an indestructible body. But Beerus points out that there is still the mystery behind Goku Black possessing a Time Ring and his energy matching Zamasu's, Future Trunks proposing that Zamasu might had killed Gowasu to become Supreme Kai and gave Goku Black the Time Ring. Shin takes Goku, Beerus, and Whis to Universe Ten to see if the theory is sound, Beerus keeping Goku from revealing the truth as he makes an inquiry on Zamasu's behavior from Gowasu. Gowasu expresses his apprentice's doubts regarding the role of a Supreme Kai and their relationship with mortals, but felt no need for concern before Zamasu arrives.

Whis gifts Gowasu with rice cakes and green tea, apologizing for his group disturbing him and Zamasu as they leave. But Beerus and Whis sensed Zamasu's murderous intention with the group remaining in space to observe him and Gowasu. When Zamasu does murder his master, Whis reverses time to avert the Supreme Kai's death. Furious that his plan was foiled, Zamasu decides to attack Goku before Beerus intervenes and atomizes the Kai. Back on Earth, after being convinced by his younger self to stop feeling bad about himself, Future Trunks learns that the present day Zamasu was destroyed with Beerus assuring him that all future versions of the Kai would also cease to exist regardless of alternate timelines. But in the future, Zamasu and Goku Black are discussing their Project 0 Mortals plan and the irony that it was only possible because of a mortal's power.

While Beerus is confident that the death of the present Zamasu has solved the crisis, Future Trunks expresses some skepticism and needs to return to his timeline to see for himself. Future Trunks proceeds to explain to Trunks the nature of alternate timelines while expressing some hope that Beerus's god status might actually averted Black's existence as he is joined by Goku, Vegeta, and Bulma. Once they arrive, the group find nothing has changed as the Saiyans and Bulma regroup with the Resistance as Future Trunks uses a senzu bean to heal Mai. The Saiyans then sense Zamasu and Goku Black approaching and face them, Goku calling Black out as a clone created by Zamasu using the Super Dragon Balls. But Black reveals himself to be Zamasu, explaining that he used the Super Dragon Balls to switch bodies with another version of Goku before killing him.

Goku Black explains that he is Zamasu from an alternate timeline where he succeeded in killing Gowasu, the Time-Ring allowing him to be unaffected by his past self's death. The other Zamasu then formally introduces himself as the Zamasu of Future Trunks' timeline, whom Black allied himself with as they destroyed the Super Dragon Balls after using them to grant Zamasu indestructibility. They then killed the other deities so they would not interfere in their goal of wiping all mortal life for their ideal utopia, saving Earth for last to have the humans suffer an agonizing demise. In the battle that follows, Zamasu and Black provoke Goku into giving the latter a challenge after revealing that Black also killed Chi-Chi and Goten when he acquired his new body and killed the alternate Goku. The two manage to defeat Goku before turning their attention to Future Trunks and Vegeta, both telling the former that his constant meddling in the timeline is the reason for Earth's misfortune. This infuriates Future Trunks, who explodes and transforms into an immensely powerful new Super Saiyan form.

Despite Future Trunks' power boost, he is only able to hold Black and Zamasu off while Goku, Vegeta, and Bulma retreat back into the present after they give Future Mai the senzu beans. Goku is taken for medical treatment while Vegeta explains what happened in Future Trunks' timeline and Black's origin to Beerus and Whis with the former taking his leave as he only remained to learn Black's connection to Zamasu. Meanwhile, Chi-Chi and Gohan meet with Krillin to ask if he knows where Goku went while finding Goten with Trunks as he intends to travel to the future. After everyone assembles, they discuss how to defeat Black and Zamasu when Piccolo proposes using the Evil Containment Wave (魔封波, Mafūba) which was used on his previous incarnation. Goku decides to learn the technique from Master Roshi's while Vegeta trains in the Hyperbolic Time Chamber, Beerus approaching Gowasu to deal with his wayward apprentice.

After being saved by the resistance, Future Trunks comes to and learns of Future Mai has found the villains' hideout and saves her after her failed attempt to snipe Goku Black. Future Trunks fights the two again and fails after attempting a suicide attack to destroy Zamasu's body, Goku and Vegeta arriving just in time to save him. Goku Black damages the Time Machine to prevent them from escaping again as Gowasu appears with Shin in an attempt to reason with his apprentice. But Black and Zamasu reveal their actions of slaughtering the other deities, with Goku learning that a Destroyer's death means their angel attendant like Whis enters an inactive state until a replacement appears. Zamasu and Black attempt to kill Gowasu before Goku and Vegeta intervene and battle them while Bulma begins repairing the Time Machine and having Future Trunks repair the sealing urn which Goku brought. Vegeta gets the upper hand over Black due to his training, denouncing his opponent as a thief who never worked to gain his power like any real Saiyan would.

Vegeta continues overpowering Goku Black, who deduced rage as a factor in Saiyan's power increasing and uses the method to increase his strength enough to cut a rift in space. Black proceeds to keep Goku and Vegeta at bay with his energy duplicates of himself while Zamasu goes after Future Trunks, Future Mai, and Bulma as they attempt to repair the Time Machine. Giving Future Trunks and Mai a video of Piccolo teaching her the Evil Containment Wave, Bulma attempts to buy them time by flirting with Future Zamasu and nearly gets herself killed. Luckily, Trunks arrives and uses the Evil Containment Wave to trap Zamasu in the jar. But Goku forget to bring the charm needed to stabilize the seal with a traumatized and weaken Zamasu breaking free as everyone regroups. Realizing that they can no longer underestimate their enemies, Goku Black and Future Zamasu use their Potara earrings to fuse into an immensely powerful being.

Immensely more powerful while possessing the abilities of his components, Merged Zamasu displays his power by devastating the Earth in the process while overpowering Goku and Vegeta. Future Trunks decides to rejoin the fight, but he is also overpowered while using his Galick Gun to hold off Merged Zamasu's Holy Wrath attack. Vegeta aids Trunks with his Galick Gun and overpower Merged Zamasu's attack, though he survives unscathed. Vegeta barely saves Future Trunks from a deadly attack before knocked out as Merged Zamasu charges a second attack before Goku intervenes with his Kamehameha.

Goku puts everything into his Kamehameha to injure Merged Zamasu, injuring his arms before using his Kaio-ken technique to knock his opponent down when he grabs his foot. But Goku collapse while Merged Zamasu begin to improperly heal, Gowasu assuming that Black's mortal body is disrupting Zamasu's indestructible body. Goku decides that the only way they can win is for him and Vegeta to fuse using Shin's Potara earrings, Vegeta reluctantly agreeing after Gowasu explains that a Potara fusion that does not involve a Supreme Kai only lasts for one hour. The newly fused Vegito powers up to Super Saiyan Blue, who dubs himself "Vegito Blue", and battles Merged Zamasu who eventually turns the table after admitting that becoming half-mortal was intended to remain true to his goals as Gowasu considers his apprentice becoming an embodiment of everything he hates. Meanwhile, after the survivors regroup with Bulma and Future Mai as they finish repair the Time Machine. Future Mai gives Future Trunks his broken sword, which inspires him to keep fighting as he channels his energy through it. Future Trunks arrives in time as Vegito's fusion abruptly ends as the result of his immense power. Future Trunks unknowingly begins gathering energy from all living things on Earth and creates a Spirit Bomb, which he channels into his sword as he runs through Merged Zamasu and cuts him in half.

The bifurcated Merged Zamasu expresses his disbelief of being defeated as he disintegrates, the victory short-lived as Zamasu transcended his physical form and is now merging himself with the universe. Infinite Zamasu wipes out everyone on Earth with only Goku and company remaining while proceeding to bleed himself into all space and time. Goku looks for another Senzu bean in his pocket when he instead finds the button that Zeno gave him, summoning the future timeline's Grand Zeno. After Goku explains the situation, Future Grand Zeno erases the future multiverse with the Supreme Kais returning to the past while Goku and the others escape using the Time Machine as Zamasu ceases to exist. Once the group return to the present, Goku and Future Trunks return to what remains of the future timeline to retrieve Future Zeno. Goku then has Shin take him and Zeno to give him Future Zeno as the promised playmate with the Grand Minister (大神官, Daishinkan) expressing astonishment to his son Whis. Whis later suggests Future Trunks and Future Mai to travel to a point in their timeline before Zamasu became a threat where he can be removed by Beerus, though it would mean they would co-exist with the new timeline's versions of them. Future Trunks and Future Mai accept the solution and depart for the new future.

Bulma attempts to secretly build her own Time Machine with no success due to needing a rare crystal that can currently be found in the Earth's core, keeping her activities a secret from Goku as he begins to gather the Dragon Balls to use one of the two unused wishes to revive King Kai. Beerus and Whis arrive on Earth soon after, Bulma taking them to a seafood restaurant to keep them in the dark. When Goku summons Shenron to provide with the wish, Android 18, Roshi, Oolong, Trunks and Goten all show up and an argument ensures. The argument worsens after the group allow Gohan to use one of the wishes to heal Pan of her fever, Bulma arriving and talking mostly everyone out of their wishes. Bulma then convinces Goku to travel to the center of the Earth to get the crystal for her in return for the last wish, only for the deities to realize what she's up to after they left the restaurant. Beerus spares Bulma while destroying the crystal and all traces of the Time Machine's existence from Bulma's lab to make his point across. The Dragon Balls then suddenly scatter as Goku was about to make his wish, Goku promising a furious King Kai that he will get another chance once the Dragon Balls reactivate.

Vegeta, Bulma, and Trunks attend a science competition that is hosted by Mr. Satan, with Goku hired for security. Dr. Senbei Norimaki of Penguin Village wins the award for his Reality Machine that conjures any item the user can think of. The ceremony is interrupted by the ghost of Dr. Norimaki's nemesis Dr. Mashirito, who used a chemical called Playtime-X to increase the hyperactive tendencies of Norimaki's powerful robot daughter Arale Norimaki to destructive levels. Vegeta attempts to stop Arale, but is sent flying after being overwhelmed by her strength and cartoon physics. Goku, recognizing Arale from when they met in his youth, transforms into Super Saiyan Blue with both equally matched. Bulma fears the fight could destroy the world, and uses the collective thoughts of the viewing audience with the Reality Machine to create a mass of delicious food. This attracts Beerus, who obliterates Dr. Mashirito when he interrupts the destroyer. Before he can do the same to Arale, the ingested food causes him severe stomach pain and prompts him to rush home with Whis. Shortly afterwards, Dr. Norimaki and Arale leave and return home, with Goku and Arale agreeing to fight again in the future.

Champa contacts Beerus and challenges him to a friendly game of baseball (野球, Yakyū) between their teams on the Seventh Universe's Earth, though Champa is using the game as an opportunity to help himself to Earth's food as Vados convinces him to join in the game. As Hit and Frost are absent, Vegeta and Goten take their spots in the Sixth Universe team. The baseball game begins with Goku as pitcher, though it is ultimately revealed that Yamcha is the only participate with experience in baseball. The Seventh Universe team take bat with Yamcha getting himself injured several times from stealing bases but staying safe, one such moment resulting in Beerus and Champa engaging each other in a fight that threatens reality before Whis and Vados intervene and call the baseball game off. Vados reveals that Yamcha actually stole home while everyone was distracted by the Destroyers' fight, with his team winning the game by one point, Champa's obsession of training his team for a rematch apparently making him forgot his initial goal.

Goten and Gohan notice their father Goku acting strangely as they spent all day following him before Gohan decides to direct the direct approach during dinner. It was after dinner that Goku admits to Gohan and Goten that someone wants to kill him. Elsewhere, as Vegeta notices Whis is hiding something while assuming Super Saiyan Blue to pass his training regime. Meanwhile, in the Sixth Universe, Hit finished assassinating a crime boss and learns his next target is Goku. Goku senses Hit coming and flies off to a remote area where no one would get caught up in their fight, Hit arrives and assures Goku that he has more than his Time-Skip. Goku finds his attacks unable to hit a tangible Hit, seemingly killed with a single invisible blow to the heart as he fires his energy attack into the air before collapsing as Piccolo, Gohan, and Goten arrive.

As it seemed Goku is beyond Piccolo's ability to heal, his heart is jump started when the energy attack he launched early in midair hits him. After telling his sons and Piccolo not to get involve, having deduced Hit's assassination technique to be an invisible energy blast, Goku leaves and calls Hit out as they resume their fight. Nearby, Champa and Vados are watching fight with the latter revealed to have served as an intermediary for Hit's client while explaining to Champa that the assassin uses the stored time from his Time Skips to create a pocket dimension which plays in his tangibility. They are later joined by Vegeta, Beerus, and Whis as Goku uses his power to damage Hit's pocket dimension with his a Kamehameha causing a double knockout. In the aftermath, Goku reveals himself as Hit's client with Whis and Vados helping set everything up so he can fight the assassin at his best. Hit takes his leave soon after, intent to fight Goku another time as the job has no deadline.

Krillin is grazed by a bullet during a shootout with a pair of burglars who Goku easily disarms.
