The Present Grand Zenō and Future Grand Zenō are playing a game together in their realm, but both have become bored with their monotonous routine. Meanwhile, Goku heads to a local farmer's market to sell his produce and get Chi-Chi off his back about making money. On the way home, he is ambushed by some robbers. Goku defeats them, but he is injured in the process. Deciding that he has grown rusty, Goku and Goten decide to train with Whis. They head to the Capsule Corporation building, where Bulma reveals she is pregnant with her and Vegeta's second child. Goten remains behind to train with Trunks. Vegeta declines to accompany Goku so that he can be with Bulma when she gives birth. Goku heads to Beerus' planet alone. While training with Whis, Goku remembers Grand Zenō's intention to hold a multiverse martial arts tournament. Heedless of Beerus and Whis' warnings, Goku uses Grand Zenō's button to head to his realm and convinces Present Grand Zenō and Future Grand Zenō to hold the tournament. When he returns to Beerus' planet, Beerus angrily berates Goku and explains that Grand Zenō's naive and innocent nature combined with his extreme power makes him a danger to the multiverse. Beerus threatens to kill Goku if he steps out of line again. Goku, Beerus, and Whis go to the Sacred World of the Kais in Universe Seven, where the Grand Minister arrives. He tells the group to assemble their ten most powerful warriors to compete in the "Tournament of Power" (力の大会 Chikara no Taikai).

The Grand Minister explains the details of the "Tournament of Power" and states that it will be held in the "Null Realm". It is a place of "infinite nothingness", where the competitors can fight without limits. The tournament champion will be granted a wish by the Super Dragon Balls, while the losers and their respective universes will be completely erased from existence. Everyone is horrified by this harsh penalty. The Grand Minister also reveals that Universes Seven and Nine are to have a Zenō Expo for Future Grand Zenō's benefit. Universes Seven and Nine are required to gather three fighters. Goku suggests asking the Present Grand Zenō and Future Grand Zenō to ignore it, but Whis advises against this. Whis tells Goku that Present Grand Zenō and Future Grand Zenō have already made up their minds and attempting to change it could be dangerous. Beerus demands that Goku takes responsibility for asking Present Grand Zenō and Future Grand Zenō to hold the tournament in the first place. Goku declares that he will defeat any opponent he faces. Goku sets off to recruit teammates. After Vegeta refuses, Goku recruits Gohan. He explains to Gohan the potential penalty of the Tournament of Power. Gohan tells Goku to keep the stakes a secret to prevent mass panic. Goku also recruits Majin Buu, who is accompanied by Mr. Satan. At Present Grand Zenō's and Future Grand Zenō's palace, all the gods and angels from all twelve universes gather. The Grand Minister explains the purpose of the Zenō Expo. He alludes to the possibility of Present Grand Zenō and Future Grand Zenō erasing the fighters that he deems unfit for the Tournament of Power. In the first match of the Zenō Expo, Majin Buu from Universe Seven is to fight a humanoid canine fighter, Basil (バジル Bajiru), from Universe Nine.

Basil quickly gains the upper hand and beats down Majin Buu, who is not taking the fight seriously and thinks of it as a game. Goku goads Basil into showing his full power to get Majin Buu's attention, which leads to Basil using his ultimate attack. As the Supreme Kai of Universe Nine, Ro (ロウ Rō), claims victory, Majin Buu emerges with a hole in his stomach, but he is otherwise unmoved. Basil and Ro are shocked to see this. Mr. Satan is injured during the attack. He tells Majin Buu to beat Basil before falling unconscious. This enrages Majin Buu to the point, where he effortlessly beats Basil and knocks him out of the ring. However, since neither Present Grand Zenō and Future Grand Zenō is satisfied with the fight, Basil is allowed to get back into the ring. Ro gives Basil a drug that makes him far more powerful. Although Beerus demands that Basil is disqualified for obvious cheating, Present Grand Zenō and Future Grand Zenō is entertained by this and allows the fight to continue. The Grand Minister announces that the rules will be improvised as the tournament goes along. Basil overpowers Majin Buu and seemingly beats him, which causes Ro to prematurely gloat about the superiority of Universe Nine. However, Majin Buu emerges unscathed and launches a full power attack at Basil. This knocks Basil out. Majin Buu wins the match and earns the victory for Universe Seven. As the Universe Nine team laments Basil's loss, Basil's second oldest brother, Lavender (ラベンダ Rabenda), says that if he is allowed to kill his opponent then he can win his match. Bergamo gives Lavender permission to kill his opponent. In the second match of the Zenō Expo, Gohan from Universe Seven volunteers to fight Lavender from Universe Nine.

As their battle begins, Lavender spits a poison mist into Gohan's eyes and blinds him. The Universe Seven Supreme Kai, Shin, offers Gohan a Senzu bean to cure the poison, but Gohan refuses and says he wants to fight with his strength alone. Unable to see, Gohan uses his other senses to track Lavender and scores several blows. Lavender counters by levitating, which eliminates the sound of his footsteps. Gohan responds by powering up to Super Saiyan and bouncing his own ki off of Lavender's body, which uses it as a kind of active radar. Powering up also causes the poison to spread rapidly through Gohan's body. Lavender mounts a comeback. In desperation, Gohan grabs hold of Lavender and launches a kamikaze attack. He drives both of their bodies into the ring at high speed. Lavender is knocked out, but Gohan is so weakened by the poison that he cannot continue. With both fighters down, the match is declared a tie. After Goku feeds Gohan a Senzu bean, the Grand Minister announces to all the gods, angels, and mortals in attendance that Present Grand Zenō and Future Grand Zenō had long believed that there were too many universes. However, Goku reminded Present Grand Zenō and Future Grand Zenō to hold the Tournament of Power. The Grand Minister states that all universes that lose in the Tournament of Power will be erased with their respective gods as well. However, Universes One, Five, Eight, and Twelve will be exempt from erasure since their Mortal Levels are above seven. The Angels from all universes will be exempt from erasure as well. Whis summarizes that Present Grand Zenō and Future Grand Zenō were planning to erase most of the universes anyway, but the Tournament of Power will afford one of the weaker universes the chance to be spared. With the announcement concluded, the ring is repaired. In the third and final match of the Zenō Expo, Goku from Universe Seven will fight Basil's oldest brother, Bergamo (ベルガモ Berugamo), from Universe Nine.

Before their battle begins, Bergamo denounces Goku before the assembled gods and angels. Bergamo pleads with Present Grand Zenō and Future Grand Zenō to rescind the rule that the universes that lose the Tournament of Power be erased. Present Grand Zenō and Future Grand Zenō agree on the condition that Bergamo beats Goku in an all out battle. Grand Minister states that if Goku holds back to cancel the erasure, Present Grand Zenō and Future Grand Zenō will immediately erase all of the universes. Both Goku and Bergamo agree to the terms. When the fight begins, Bergamo invites Goku to hit him and leaves himself exposed. Goku obliges and strikes Bergamo several times, but Bergamo absorbs the energy of Goku's attacks. He grows stronger and physically larger. Goku continues to attack, which causes Bergamo to grow so large that the ring begins to buckle under his weight. Goku transforms into Super Saiyan Blue, which shocks the gods and quickly overwhelms Bergamo with a Kaio-ken powered Kamehameha. Bergamo claims every universe participating in the Tournament of Power will seek vengeance on Goku for making them face erasure, but Goku relishes the idea of such a challenge. The Zenō Expo comes to a close. The Tournament of Power will begin soon. The universe with the most fighters remaining or the last fighter standing will be declared the winner. Suddenly, a mysterious fighter from Universe Eleven named Top (トッポ) appears and challenges Goku to a battle. After Goku's short fight with Bergamo, Goku agrees to fight Top.

After obtaining Present Grand Zenō and Future Grand Zenō's blessing to proceed, Goku and Top begin their battle. Top quickly gains the upper hand and dislocates Goku's shoulder. Goku responds by attacking with a flurry of blows, but Top manages to grab Goku in a powerful bear hug. He begins squeezing the life out of Goku, which forces Goku to turn Super Saiyan Blue to escape. Goku gains the upper hand in this form and damages Top with a Kamehameha. Just as the two power up even more, the Grand Minister puts an end to the fight. As Top leaves, he reveals to Goku that Universe Eleven has a warrior even stronger than him named Jiren The Gray (ジレン). The Grand Minister begins creating a martial arts stage suitable for the Tournament of Power. In Universe Seven on the Sacred World of the Kais, Beerus and Goku get into an argument over Goku's constant relaxed and negligent attitude, which Whis breaks up. The group agrees to convene at the Capsule Corporation to discuss their future strategy.

Goku and the others arrive at Capsule Corporation. They discuss who should be on the team. Goku immediately suggests Monaka, but Beerus tells him that Monaka is sick and cannot participate in the Tournament of Power. Goku and Gohan agree on Majin Buu, Vegeta, Piccolo, Krillin, Master Roshi, No. 18, and No. 17, which would bring the total number of fighters up to nine. Trunks and Goten are ruled out due to their inexperience. They proceed to ask Vegeta, who has been thinking of a name for his second child. Vegeta refuses to participate in the Tournament of Power. He says he will not fight, while Bulma is pregnant. Whis uses his time warping ability to birth the baby sooner than expected in order to get Vegeta to participate in the Tournament of Power. Everyone celebrates the baby's birth. Trunks is slightly disappointed he has a younger sister because he wanted to train with a younger brother. As soon as the baby is handed to Vegeta, he develops an attachment to her. Bulma names the baby Bulla even though Vegeta hoped to give her the Saiyan name Eschalot. However, Vegeta quickly accepts Bulla's name. Goku leaves to recruit team members and flies to Krillin's house.

Goku and Gohan arrive at Krillin's house and ask him and No. 18 to join the Tournament of Power. No. 18 convinces Krillin to participate in order to put his newfound martial arts training to use. No. 18 is reluctant to join herself. She quickly suspects Goku and Gohan of hiding something from them, but Goku convinces her that the secret is a 10 million Zeni reward, which convinces her to participate. Gohan decides to test Krillin in a sparring match on the coast. After Gohan overpowers him in hand to hand combat, Krillin swiftly defeats Gohan by blinding him with his new move named Solar Flare x 100. Krillin knocks Gohan into the sea. Goku is excited by Krillin's new power. He challenges him to a sparring match as well. They relocate to a building owned by Mr. Satan, where Krillin's strategies make up for the gap in power. This forces Goku to go Super Saiyan. Goku transforms into his Super Saiyan Blue form. Goku and Krillin have a Kamehameha clash. As Goku increases his power and starts to overpower Krillin, No. 18 intervenes and blocks Goku's Kamehameha. Krillin collapses from exhaustion. No. 18 justifies herself by noting that the Tournament of Power will be a battle royal and that Goku cannot expect to fight one-on-one all the time. Goku concedes the match and realizes he will have to adjust his tactics in order to win the Tournament of Power. No. 18 reveals that No. 17 is currently working at a wildlife reserve, but she does not know where it is. Goku decides to ask Dende to find No. 17.

Gohan leaves to recruit Piccolo, while Goku prepares to go to Dende's Lookout. He encounters Majin Buu and Mr. Satan training. Goku discovers that Majin Buu has lost weight and has gotten much slimmer in appearance. The two spar together. Majin Buu defeats Goku by overwhelming him with ki blasts and knocking him out of the fighting stage. Meanwhile, the Supreme Kai of Universe Eleven, Cae (カイ), gathers all of the Supreme Kais involved in the Tournament of Power except for Universe Seven's Supreme Kai, Shin, who is ostracized due to Goku's involvement with the creation of the Tournament of Power. Cae asks his fellow Supreme Kais to request that Present Grand Zenō and Future Grand Zenō cancel the erasure of the universes, but they are all too afraid of his wrath to do so. Champa gathers all the Gods of Destruction involved in the Tournament of Power except Beerus after finding out about the Supreme Kai's meeting. They discuss Goku. Top recruits his fellow Pride Troopers Kahseral (カーセラル Kāseraru) and Dyspo (ディスポ Disupo). Champa recruits Cabba and demands he find more powerful Saiyans. Goku meets Dende and Mr. Popo at Dende's Lookout and learns No. 17's location. Gohan prepares to train with Piccolo.

On their way to the island where No. 17 is working, Dende explains that since the conclusion of the Cell Games, No. 17 has started a family and gotten far stronger. Dende also reveals that Kid Buu has been reincarnated as a young Earthling with massive fighting potential and asks Goku to train him when he is old enough. They reach the island as Goku arrives just in time to witness No. 17 defeat a group of armed poachers. As they introduce themselves to each other, a large army of poachers arrive. Goku and No. 17 team up to subdue them all. Afterwards, No. 17 explains that the poachers are after the last Minotaurus in order to steal its rare and valuable horns. Goku and No. 17 decide to have a sparring match. No. 17 evenly matches Super Saiyan Goku, which causes him to turn Super Saiyan Blue. Goku launches a Kamehameha at No. 17, who easily deflects it with an energy shield. No. 17 and Goku go toe-to-toe until No. 17 ends the match in order to avoid catching the island in the crossfire. Goku and No. 17 acknowledge that they were both holding back in the fight. Afterwards, Goku attempts to convince him to join the Tournament of Power, but No. 17 is uninterested. He remains indifferent even when Goku reveals that all the losing universes will be erased from existence. Meanwhile, alien poachers arrive on Earth. The alien poachers set their sights on the Minotaurus.

Goku entices No. 17 with a wish on the Super Dragon Balls. As he begins to consider Goku's offer, the alien poachers arrive and abduct all of the island's animals. Goku uses his Instant Transmission to teleport himself and No. 17 aboard their space ship before it can escape. After defeating some of the alien poachers, No. 17 sets off to defeat the leader, while Goku remains behind to battle the rest of the alien poachers. No. 17 confronts and easily defeats the leader. Goku catches up just as the leader pulls out a switch and threatens to self-destruct if he is not released immediately. No. 17 smashes him out of a window, which vents both of them into deep space. Goku manages to use his Instant Transmission to teleport all three of them to King Kai's world. Dende contacts Goku and informs him that the leader's threat was a bluff. Afterwards, Goku and No. 17 return the animals to their rightful homes. Jaco arrives to arrest the alien poachers. No. 17 decides to leave his island in the hands of Goten and Trunks. No. 17 accepts Goku's offer to fight in the Tournament of Power. No. 17 hopes to use the Super Dragon Balls to wish for an expensive boat and travel the world with his family.

Gohan and Piccolo engage in intense training. Piccolo explains that Goku has already informed him about the potential erasure of the universe and that he is going to participate in the Tournament of Power. He points out that Gohan's over eagerness to protect his loved ones is making him reckless. Gohan transforms into a Super Saiyan, and the two continue to spar. Meanwhile, Cabba heads to the residence of his retired captain and mentor, Renso (レンソウ). Cabba asks him to join Universe Six's team for the Tournament of Power, but Renso refuses due to an injury to his leg. Renso suggests his sister, Caulifla (カリフラ Karifura), instead, who he claims is even stronger than him. Back in Universe Seven, Piccolo removes his weighted clothes to go all out and quickly defeats Gohan. Piccolo explains that Gohan has a tendency to become arrogant when he has the advantage in battle. After being encouraged by Piccolo, Gohan manages to reach the level of power he had against Super Buu. The two fight again, and Gohan successfully severs Piccolo's arm. However, Piccolo blasts him in the back with the severed arm and defeats Gohan, which proves Piccolo's point about Gohan's overconfidence. That night, Piccolo vows to push Gohan to new heights of power. They both agree to work on combination moves.

Goku flies to Master Roshi's island, where Oolong informs him that Tien and Chiaotzu have started a martial arts dojo. Master Roshi has headed there to act as a special instructor. Goku decides to make Tien the tenth member of the team. He heads off to recruit Tien and Master Roshi. At Tien's dojo, a woman named Yurin (ユーリン Yūrin) with a grudge against Tien arrives and requests to join the dojo. Although Tien denies her because her motivation of beauty was unfit for his dojo, Master Roshi drags Yurin off to ogle her. Goku arrives and asks Tien to join the Tournament of Power. After Goku bribes him with ten million Zeni, Tien refuses to join the Tournament of Power. Yurin escapes Master Roshi's advances and uses witchcraft to drive Tien's students on a rampage throughout town. Goku, Tien, Chiaotzu, and Master Roshi arrive at the village, where Yurin confronts them. Yurin explains that she is a former classmate of Tien's during his time at the Crane School and that she swore revenge on him after he left the school and refused to fight her. Meanwhile, Cabba sways Caulifla into joining Universe Six's team by promising to teach her how to become a Super Saiyan. Back on Earth, while Goku, Chiaotzu, and Tien cure the students of their brainwashing, Master Roshi battles Yurin. He lowers his guard after catching a glimpse of Yurin's panties, which allows her to brainwash him. The brainwashed Master Roshi quickly defeats Tien, but Goku intervenes. While Chiaotzu temporarily disables Yurin, Goku subdues Master Roshi with a Kamehameha and cures him of the brainwashing. Tien orders Yurin to apologize to everyone she hurt and offers her a place at his dojo. Tien decides to join the Tournament of Power because he believes that the ten million Zeni Goku promised will repair the village. After hearing about the ten million Zeni, Master Roshi quickly agrees to join the Tournament of Power.

As Gohan finishes training with Piccolo, they go to meet with Goku, Master Roshi, Tien, and Chiaotzu. At Gohan's request, Goku and Tien have a fight against Gohan and Piccolo to practice for the Tournament of Power. Although Tien views this as a practice match and wants to avoid injuring anyone, Gohan and Goku take the fight seriously. As Gohan fights both his father and Tien, Piccolo spends the time charging a strong technique, which ultimately destroys the mountain fighting stage when it is launched. Tien calls the match off on the grounds that the fighting stage is now destroyed. Although Goku agrees, Gohan requests to have a one-on-one fight against his father. Goku accepts Gohan's request. Gohan powers up, while Goku goes Super Saiyan 2. Although Goku has the upper hand for much of the fight, Gohan turns the tables and begins to overpower Goku. Gohan begs Goku to use his full power. Goku responds by becoming a Super Saiyan Blue and using his Kaio-Ken technique. Goku defeats Gohan with a single blow. Impressed with his son's improvement, Goku assigns Gohan as the leader of their Universe Seven team. Meanwhile, the God of Destruction of Universe Ten, Rumush (ラムーシ Ramūshi), recruits a powerful fighter named Mulithim (ムリチム Murichimu) and his nine companions to represent Universe Ten in the Tournament of Power.

Present Grand Zenō and Future Grand Zenō are suffering from extreme boredom again. They decide to observe the universes' progress in assembling their strongest warriors. In Universe Seven, Vegeta prepares to enter the Hyperbolic Time Chamber for some intense training. Goku spars with Whis in Vegeta's gravity chamber. Master Roshi and Puar train to remove Master Roshi's weakness to seduction techniques, which fails miserably. In Universe Nine, word has spread of the potential erasure of their universe. The populace has descended into anarchy. The three canine brothers have been unable to find any other fighters. In Universe Six, Hit tracks down the destitute Frost and forces him to join the Tournament of Power, while he relieves him of his poison needles in the process. In Universe Eleven, Top's comrade named Casserale (カーセラル Kāseraru) is delayed from joining when he helps a cat stuck in a tree. In Universe Two, a magical girl named Brianne de Chateau (ブリアン・デ・シャトー Burian de Shatō) transforms into her alter ego named Ribrianne (リブリアン Riburian) and auditions for a spot on the Universe Two team in the Tournament of Power. In Universe Ten, Mulithim and his nine companions record a dance video to improve team spirit. In Universe Seven, Mr. Satan calls and unexpectedly reveals that Majin Buu has fallen into a deep sleep and cannot join the Tournament of Power, which horrifies everyone.

Goku races to Mr. Satan's house, where he proves unable to wake Majin Buu from his hibernation. Meanwhile, all of Universe Seven's remaining warriors except Master Roshi and No. 17 gather at the Capsule Corporation. After Krillin brings up the ten million Zeni prize that Goku had bribed him, Piccolo and Gohan reveal to Krillin, No. 18, and Tien that the prize of ten million Zeni was a lie and that the universe will be erased if they lose. When Goku returns, Krillin berates him and threatens to withdraw from the team along with No. 18. After Goku fails to convince them otherwise, Beerus swiftly threatens Krillin into staying. Bulma agrees to pay out the promised reward of ten million Zeni to each Universe Seven team member who wants it. In Universe Six, Cabba takes Caulifla to a deserted wasteland to teach her how to become a Super Saiyan. As Caulifla's protégée, Kale (ケール Kēru), observes them, Cabba ineffectually attempts to provoke Caulifla in order to make her transform. When that fails, he teaches her to focus her energy on an area in her back. Caulifla successfully transforms into a Super Saiyan. Caulifla tests her newfound power and agrees to join Universe Six's team for the Tournament of Power. She beckons Kale over to attempt the transformation herself. In Universe Eleven, Casserale arrives at the Pride Trooper headquarters, where he and Top agree to leave Universe Eleven in their Pride Trooper's trainees' hands to protect it so they can participate in the Tournament of Power. In Universe Three, two cyborg warriors named Nigrissi (ニグリッシ Nigrisshi) and Narirama (ナリラーマ Narirāma) display their upgrades for the Tournament of Power to Universe Three's God of Destruction Mosco (モスコ Mosuko), Universe Three's Supreme Kai Ea (エア Ea), and Universe Three's Angel Camparri (カンパーリ Kanpāri). In Universe Seven, Goku and his friends are unable to figure out who can replace Majin Buu. When Beerus claims they have no suitable fighters because Goku destroyed the Frieza Force, Goku is inspired to recruit Frieza, which shocks everyone.

Goku's idea is met with much hesitance from his team members. Goku explains that he intends to have Fortuneteller Baba resurrect Frieza for twenty four hours to fight in the Tournament of Power. If Frieza betrays them then either he or Vegeta can defeat him. Goku's friends reluctantly agree, and he uses instant transmission to teleport to the Other World. The Universe Seven team are unaware that a spy from Universe Four is observing them. In Universe Six, Cabba and Caulifla attempt to teach Kale how to turn into a Super Saiyan but to no avail. Kale begins to despair over her own uselessness, and it enrages her enough to trigger her transformation into an extremely powerful Legendary Super Saiyan. Kale immediately goes berserk and attacks Cabba. Caulifla quickly deduces that Kale is jealous of her and Cabba's perceived relationship. She denies having any sort of feelings for Cabba. Kale calms down and collapses in Caulifla's arms. Cabba, who is impressed by Kale's power, decides to add her to Universe Six's team. In Universe Seven, Goku arrives in the Other World and receives King Yemma's permission to visit Frieza. Goku explains about the Tournament of Power and asks Frieza to join them. Frieza agrees to aid him on the condition that he be properly resurrected with Earth's Dragon Balls. When Goku hesitates to agree, Frieza goads him by playing to his desire to see how powerful Frieza can become. Goku accepts his terms. In Universe Four, Ganos (ガノス Ganosu) reports Universe Seven's latest actions to Universe Four's God of Destruction Quitela (キテラ Kitera), Universe Four's Supreme Kai Kuru (クル Kuru), and Universe Four's Angel Cognac (コニック Konikku). Quitela immediately begins making plans to counter Beerus.

Quitela contacts Universe 9's God of Destruction Sidra (シドラ Shidora) and informs him that Universe 7 is planning to use Frieza to assassinate their rivals before the tournament begins and that the only way to counter them is to kill them first. Sidra and Roh agree to have Frieza killed. Meanwhile, Goku returns to the Capsule Corporation to update everyone on his success. As Master Roshi completes his training at Korin's tower, Krillin and No. 18 head to No. 17's island to pick him up and drop off Goten, Trunks, and Marron. Goku goes to Fortuneteller Baba's home, where she completes the ritual to resurrect Frieza. As Goku and Frieza prepare to depart, an army of assassins arrives to claim their heads. Despite the time pressure, Frieza wounds the assassins' leader, transforms into his Golden form, and prepares for battle.

Frieza explains to Goku that he spent his recent incarceration in Hell undergoing intense mental training to overcome the stamina issues that plagued him during his previous battles with the Z-Fighters. He quickly slaughters most of the assassins, which horrifies Goku. The assassins' leader, who has been directly empowered by Sidra, attacks Frieza with Sidra's power, but Frieza manages to overcome and hijack the attack. Frieza spitefully uses the attack on Goku and traps him. Frieza tortures and kills the assassins until they reveal that Roh and Sidra hired them. Frieza contacts Universe 9 and offers his services as a defector. Roh and Sidra begin arguing about whether or not to accept him. Roh fears Frieza's psychopathic and treasonous nature, while Sidra wants his power. Sidra is confident he could kill him if he stepped out of line. Their argument buys time for Beerus and Whis to arrive and rescue Goku. Frieza cuts the connection. He begins making plans to use the Tournament of Power to manipulate the gods to suit his own ends. Goku and Frieza have a brief sparring match, which ends in a draw. Goku, Frieza, Beerus, and Whis return to the Capsule Corporation. The Universe 7 team prepare to travel to the Null Realm for the Tournament of Power.

In the Null Realm, Universes 1, 5, and 8's Gods of Destruction Iwne (イワン Iwan), Arack (アラク Araku), and Liquiir (リキュール Rikīru) have a brief exhibition match to test the durability of the Tournament of Power's fighting stage. Afterwards, the Grand Minister forces them all to clean up their mess and fix the stage. In Universe 7, Gohan and Shin's strategy is to have the team members stick together to conserve energy and use strength of numbers to defeat anyone who attacks them. This suggestion offends Goku and Vegeta's Saiyan pride. Whis transports the team to the Null Realm. All of the other universes arrive. Frieza and Frost befriend each other and agree to work together, while Goku singles out Jiren as a potential rival due to his extreme power. As the Grand Minister introduces each team, Universe 4 seemingly has only 8 warriors on their team, which confuses most of Universe 7, except for Tien, who tells No. 18 that he can sense a faint presence. After a speech from the Grand Zenō and Future Grand Zenō, the 80 warriors prepare for battle.

The Grand Minister reminds everyone of the rules and officially starts the tournament. A massive free-for-all ensues. Goku targets Top, but he is intercepted by Ganos. Disregarding Gohan's plan as well, No. 17, No. 18, Vegeta, and Frieza all jump into the fray. Universe 3 gains an early advantage when Narirama unleashes a spinning attack designed to knock its opponents off the stage, but Hit and Basil disable it. Universe 10's Lilibeu (リリベウ Ririberu) attacks Basil, but Basil successfully knocks her off the stage. Meanwhile, the five Universe 7 warriors who stayed together are confronted by a gang of warriors from varying universes, but Universe 7 uses teamwork to fend them off. Basil nearly defeats Universe 10's Napapa, but Napapa is able to push his attacks away at the last moment. As Goku is pursuing Top, he comes face to face with Jiren until Universe 4's Nink (ニンク Ninku) outflanks Goku by grappling and dragging him towards the edge of the stage with the intention of jumping off with him. Goku turns Super Saiyan Blue and knocks Nink off the stage. As Goku reverts back to his normal form to conserve energy, Basil, Lavender, Bergamo, and two other Universe 9 warriors surround him with 47 minutes remaining in the tournament.

Roh orders his warriors to attack Goku to avenge their defeat at the Zen Exhibition Match. Goku is forced to avoid fighting at his fullest in order to conserve stamina for later in the tournament. He fights Team Universe 9, where the Trio de Dangers brothers manage to overwhelm him thanks to their teamwork. Vegeta notices Goku's plight and reinforces him. Roh sends over three more fighters. Team Universe 9 is able to push Goku and Vegeta to the brink until Vegeta tricks Lavender and Hop (ソレル Hoppu) into accidentally hitting each other. Goku and Vegeta take advantage of the confusion to defeat five of the Universe 9 warriors. No. 18 and Frieza each defeat Sorrel (ソレル Soreru) and Roselle. Only Basil, Lavender, and Bergamo remain in the tournament for Team Universe 9. Goku and Vegeta push them to the edge of the stage. The brothers use a combination beam as a last ditch effort, but Goku and Vegeta power up to Super Saiyan Blue and knock them off the stage with a Final Kamehameha. With all 10 members defeated, Universe 9 is eliminated from the tournament. As a result, Grand Zenō and Future Grand Zenō erase Universe 9, Roh, Sidra, and all of their fighters. This amuses Universe 9's angel Mojito (モヒイト Mohi'ito) and horrifies everyone else.
