Vegeta and Trunks arrive in Universe 11, and discover that Hearts and his gang are already there attacking. Oren catches the Saiyans off-guard and possesses Vegeta's body, gaining his immense power for himself. Trunks attacks Oren, but he is easily defeated. Meanwhile, Jiren is fighting Cumber: they appear to be evenly matched, so Cumber transforms into a Super Saiyan, but Jiren is still holding his own until Hearts appears and calls off the fight. Oren takes over fighting Jiren, while Hearts sends Cumber to attack Universe 3 instead. Kamin and Zamasu join the battle against Jiren; Trunks tries to help by attacking Zamasu, but Oren swiftly defeats him again. Just as Oren is about to finish off Trunks, Goku arrives with the Grand Minister. The Grand Minister departs, and Goku demonstrates that he now has some control over Ultra Instinct.

On the unknown planet, Vegeta, Turles and Cumber begin fighting each other. Cumber temporarily disables Vegeta and continues fighting Turles, while Goku and Hearts arrive to help Vegeta. They are confronted by the masked Saiyan, who reveals himself as...

Vegeta and the others try to attack Hearts while he is absorbing the Universe Seed, but Zamasu stands in their way as he reveals that he is only aiding Hearts so he can resume his scheme without the Zenos' interference. Zamasu overpowers Goku after quickly incapacitating the others before Jiren and Hit arrive to join the fight, having been sent by their universes' Supreme Kais to deal with Hearts and his allies. Goku, Jiren and Hit are about to attack Zamasu again when Hearts suddenly emerges from his crystal construct, having assimilated the Universe Seed and its power into his body. Hearts uses his new power to easily immobilize Zamasu, then obliterates him after revealing that his goal is to destroy all the gods. The Grand Minister is disturbed from sensing Zamasu's death, as Hearts proclaims himself to be "the Godslayer."

Goku begins fighting Kamioren, and the two seem to be fairly evenly matched in terms of power, until Goku reaches the mastered level of Ultra Instinct and easily deflects Kamioren's attacks. He overwhelms Kamioren with help from the others, damaging them with a Kamehameha and a barrage of energy blasts before shattering their core with a final punch, causing their body to disintegrate. Goku loses his Ultra Instinct again, while Hearts expresses sorrow over the deaths of Kamin and Oren, before retrieving the now fully-charged Universe Seed from Kamioren's remains. Hearts begins absorbing the power of the Universe Seed, surrounding himself in a huge cloud of crystal cubes. Meanwhile, Zamasu looks on in satisfaction, but also seems to have his own agenda.

Gogeta launches an energy blast at the meteor, slowing it down and temporarily holding it in place. Hearts uses his full strength and overpowers Gogeta's blast, propelling the meteor forwards again, so Gogeta powers up even more, charges up a Kamehameha and fires it at the meteor instead. Trunks is worried that the Earth will be destroyed, but Piccolo refuses to give up. Hit and Jiren join Gogeta and add their own blasts to the Kamehameha, increasing its power and ultimately shattering the meteor. Trunks, Piccolo and 17 shield the Earth from the meteor's fragments, while Gogeta and Hearts engage in a final clash. Gogeta overpowers Hearts and delivers a finishing blow that shatters the Universe Seed embedded in Hearts's chest, causing his body to disintegrate. As he dies, Hearts explains that he was merely trying to free all mortals by defeating the Omni-Kings, as their power to destroy entire universes on a whim prevents mortals from ever being truly free.

Xeno Trunks identifies the new arrivals, Majin Salsa and Putine, as demons and old enemies of the Time Patrol. However, the demons offer to help the heroes in their efforts to destroy Fu's Universe Tree, warning that the Tree is continuing its work of consuming countless planets across the multiverse. Janemba attacks them all again before the two groups can come to an agreement, and the battle resumes, with Xeno Trunks powering up to Super Saiyan God. Majin Salsa suggests that Xeno Goku and Xeno Vegeta use a mysterious technique that they have employed in the past, so the other Saiyans all power up and channel their energy into the pair while the two demons hold off Janemba. By absorbing the others' energy, Xeno Goku and Xeno Vegeta break through their limits and achieve a higher level of strength, known as Full-Power Super Saiyan 4. They attack Janemba together, succeed in overpowering him, and are finally able to destroy him using their ultimate technique, the Double Dragon Fist.

After an endless fierce battle, Ultra Instinct finally goes into operation. Amidst the crumbling Prison Planet, a final battle begins with everything on the line!

Oren and Kamin suddenly convert their bodies into energy and possess Kale and Caulifla, using their bodies to attack the others. Vegeta, Trunks and Hit develop a plan; Trunks and Hit fight and immobilize Oren and Kamin, with the siblings forced to abandon their host bodies when Vegeta fires a Final Flash at them. Before the battle can continue, Hearts appears with a strange crystal and immobilizes all of them with his psychic powers.

After powering up, Hearts attacks Goku and their battle intensifies, with Hearts holding the advantage until Goku powers up to Super Saiyan Blue, after which they appear to be evenly matched. However, they both acknowledge that neither of them is fighting all-out yet. Goku is able to gain the upper hand and overpowers Hearts with a Kamehameha. Meanwhile, Trunks and Vegeta continue their battle with Zamasu, while 17 and Piccolo are able to catch Kamioren off guard, with 17 holding off their attacks while Piccolo charges up a Special Beam Cannon that wounds them. However, Kamioren regenerates and powers up wildly, enraged by the possibility that they could lose. Hearts gets back up and powers up again, using his control of gravity against Goku; Goku is able to withstand his attacks, so Hearts powers up even further.

A mysterious figure looks out over the new universe's version of West City. Nearby, Goku has been attacked by Frieza and Meta Cooler. In the process, he is contacted by Xeno Trunks, who is at the Time Nest with Xeno Pan, Xeno Gohan, Xeno Goten, and the Supreme Kai of Time. Xeno Trunks informs Goku that what Fu has actually created is merely a copy of the Seventh Universe; interestingly, any damage inflicted on the buildings in the alternate West City is also transferred over to the real West City.

Fu is horrified by the Universe Tree's death, until Towa and Mira arrive to help him. Towa infuses Mechikabura's energy into Fu, dramatically increasing his power and causing him to undergo a transformation into the new Demon King. However, Fu expresses no interest in this, and begins using his new powers to restore the Tree instead. Vegito tries to stop him and their fight resumes, but Towa and Mira intervene to help Fu and buy time for him by attacking Vegito. Before Fu can finish restoring the Tree, however, a portal opens and Xeno Vegito emerges, now powered up to Full-Power Super Saiyan 4 and accompanied by the Demon God Demigra. Xeno Vegito attacks Fu, and the battle resumes. Meanwhile, in an unknown location, an alternate version of Broly awakens.

Hearts launches a simultaneous attack on all of the Z-Fighters, who struggle to fight back. Goku powers up to Super Saiyan Blue and attacks him, but Hearts easily knocks him away and then uses a massive gravity attack to take down all of the fighters at once. As the others recover, Jiren and Hit go after Hearts again, while Goku suggests that he and Vegeta use the Fusion Dance to make themselves strong enough to take on Hearts' new power. Trunks, Piccolo and 17 rejoin the battle to buy time, while Goku and Vegeta perform the dance successfully and fuse into Gogeta. The other fighters stand down for the time being, as Gogeta prepares to battle Hearts.

Xeno Vegito begins fighting Fu; the two of them seem to be evenly matched, until Fu uses his dark magic to change the area around them. He manifests a large combat arena for them to fight in, and prepares to engage both Vegitos in battle until the three of them are interrupted by the sudden arrival of the alternate Broly in his Legendary Super Saiyan form. Xeno Vegito overpowers Broly, until Broly also transforms into a Full-Power SS 4. The main timeline's Vegito joins the fight and the two Vegitos battle Broly together, but even the two of them together struggle against his monstrous power. Meanwhile, Fu uses his magic to fully revive the Universe Tree. The main-timeline Vegito continues fighting Broly, while Xeno Vegito goes after Fu, but the Tree suddenly releases a massive wave of light that engulfs Fu, Broly, and the main-timeline Vegito. Xeno Vegito escapes, while Majin Salsa, Putine, Dr. W, Turles, the captive Cumber and Hearts's spirit body are all enveloped by the energy wave.

Chronoa explains that Majin Ozotto is a notorious criminal the Time Patrol had been tracking. Ozotto attacks the Elder Kai, having already absorbed Supreme Kai and Kibito, but is interrupted by Xeno Goku and Vegeta. He transforms into Baby and battles them, then has duplicates transform into Frieza and Perfect Cell to battle them. Chronoa's group goes to Namek, but all the Namekians have already been absorbed. They find another Ozotto preparing to consume the planet and challenge him. After Xeno Goku and Vegeta defeat the duplicates, the intrigued Ozottos reveal their desire to absorb everyone to have all their powers and invites both groups to the Ozotto Mansion. They teleport away, leaving invitation cards behind.

Joined by Xeno Goku and Vegeta, the group goes to the Ozotto Mansion, but makes Chronoa stay behind to not risk her. They blast the mansion, but it is unaffected. Ozotto's voice challenges them to split up and enter 5 different entrances. If they find and defeat the real Ozotto, everyone he ate will be freed. Goku finds and battles an Ozotto duplicate using Ultra Instinct; the duplicate changes to Turles, Bojack, and Meta Cooler and they are evenly matched. Vegeta finds a duplicate who changes to Super Janemba's form. After giving Vegeta a beating, the duplicate says he is too weak to be a meal and would rather eat Goku. Enraged, Vegeta uses Super Saiyan Blue Evolved and blasts him with Final Flash. Meanwhile, Gohan wakes up in a pod and finds Goten, Trunks, and others unconscious in pods. As he struggles to break free, Ozotto taunts him and explains that they are all inside his body.

Something crash lands on Earth. Everyone goes home from the Super Space-Time Tournament, but Chronoa, Vegeta, Gohan, Piccolo, and Xeno Trunks wait for Goku to wake up. Chronoa attempts to send them to Earth, but it is gone. Shocked, they go to King Kai's planet, but are greeted by Majin Ozotto, who explains that he ate King Kai and his companions, plus everyone and everything on Earth. Now he aims to eat more gods and attacks Chronoa. The others defend her and fight him with Goku and Vegeta using Super Saiyan Blue, Xeno Trunks using Super Saiyan God, and Gohan using Mystic Form, but he quickly absorbs Piccolo and Gohan. When they damage him, he reveals he gained regeneration from absorbing Buu, plus his detached parts can shapeshift into anyone he absorbed, which he demonstrates with Android 17 and 18. He merges with his duplicates and his power skyrockets. Realizing the battle is hopeless, Chronoa teleports herself, Goku, Vegeta, and Xeno Trunks away.

Goku uses Ultra Instinct to dodge "Giant Fat Form" Ozotto's attacks and counterattack. Ozotto is eager to gain his powers and summons an army of duplicates. Xeno Goku, Vegeta, and Trunks continue to fight duplicates. One duplicate turns into Chronoa and uses her time powers, but Xeno Goku frees the unconscious Chronoa from her pod, making her duplicate disappear as Ozotto rages against losing his time powers. Hearts and Lagss carry all the unconscious prisoners out of Ozotto's body. Goku eliminates the duplicates and uses the Dragon Fist to destroy Ozotto. As Goku sees that Chronoa, Xeno Goku, Vegeta, and Trunks are safe, he passes out from exhaustion. Aeos appears and congratulates Goku. Ozotto's remnants slowly regenerate and try to escape, but Aeos traps him in a jar. She then uses the Super Dragon Balls to restore all the destroyed planets and return everyone home.

An Ozotto seizes Chronoa. After defeating the villain duplicates, Xeno Trunks, Goku, and Vegeta find Ozotto strangling Chronoa, then sealing her in a pod. He attacks them with tentacles, then an army of duplicates while gloating that he now has power over time, but he still wants more. Goku, Vegeta, and Gohan are attacked by tentacles, but Hearts and Lagss show up to help. They start freeing unconscious people from pods, but have to fight off Ozotto duplicates. Hearts detects Ozotto has a hidden, vulnerable organ and the outer wall. After Hearts clears the way of duplicates, Vegeta uses Super Saiyan Blue Evolved, flies to the wall, and uses Final Explosion to blow a hole in it. Goku flies out of the hole in "Giant Fat Form" Ozotto's stomach with an unconscious Vegeta and prepares to face him with Ultra Instinct. Meanwhile, Aeos becomes aware of what is happening.

Ozotto taunts Gohan by hurting Goten and Trunks, but when he threatens Videl, Gohan explodes with rage, breaks free from his pod, and attacks Ozotto. After defeating their opponents, Xeno Trunks, Xeno Goku, and Xeno Vegeta contacts each other and realize they cannot contact Chronoa. Goku and Vegeta break into the area where Gohan and Ozotto are fighting after killing the other counterparts of Ozotto, but Ozotto uses the distraction to reabsorb Gohan, and his power skyrockets. With little options, Goku and Vegeta use the Potara to fuse into Vegito. Vegito uses Super Saiyan Blue Kaio-Ken and obliterates Ozotto, causing a heavily injured Gohan to reappear, just before he separates. As Goku and Vegeta check on Gohan, he warns them that they are inside Ozotto. As he says this, the entire mansion morphs into a "Giant Fat Form" Ozotto. Meanwhile, Xeno Trunks, Goku, and Vegeta are threatened by several duplicates of past villains.

Dr. W begins what he calls an "analysis" of Xeno Goku and Xeno Vegeta by attacking them with strange, teleporting energy blasts. They both power up to Super Saiyan 3 and engage him in combat, but he is able to hold them both off with his strange attacks and high-speed reflexes. After having difficulty overpowering him, they power up to Super Saiyan 4 and land a powerful combined blast on him; however, Dr. W deliberately takes their attacks head-on, and emerges from the smoke with a glowing golden aura identical to theirs. Having completed his analysis, he then opens a portal and escapes. Meanwhile, Fu is observing the battle between Goku, Vegeta, Turles and Bojack. He releases Doki-Doki, who generates waves of dark energy that immobilize Goku, Vegeta, Xeno Trunks and Xeno Pan. Toki-Toki tries to defuse the dark energy, but Fu traps him and throws him through a portal, before recalling Doki-Doki and escaping through one himself.

Xeno Vegito outruns the energy wave before it dissipates, leaving the area around the Tree unscathed; he returns to find Fu holding the miniaturized form of the new universe created by the Tree. However, Fu is disappointed by his creation, as the new universe is flawed because Fu had to use his own demonic power to refuel the Tree rather than the pure energy of a normal universe. A furious Xeno Vegito attacks Fu, determined to stop him from doing anything else, and their battle resumes. Towa challenges Demigra, but his female companion takes her on instead, while Demigra uses a mystical technique known as "Time Labyrinth" to freeze both Xeno Vegito and Fu in time. Towa claims that Fu will be able to escape the frozen-time bubble, but Demigra is confident that he will not. On Beerus's planet in the Seventh Universe, Whis and Vados sense the creation of the flawed new universe. Meanwhile, in the new universe, Goku awakens alone, in a strange, empty version of West City.

The rest of the group from the Prison Planet have made it safely back to Beerus's planet, where they regroup with Whis. Xeno Goku and Xeno Vegeta return to their own universe, wishing the others good luck. Suddenly, the Supreme Kai of Universe 6 appears

The new arrivals are revealed to be Gohan, Krillin, Android 17, and Android 18, who have been transported into the new universe. Majin Salsa and Putine also join the group, accompanied by Shurum, a former Demon God and an ally of Demigra, who helped to retrieve Cell and Hearts from Hell.

Goku, Vegeta, Xeno Goku, Xeno Vegeta, Xeno Trunks, Xeno Pan, Majin Salsa and Putine arrive on the Universe Tree, which is still absorbing energy from the multiverse. Vegeta attempts to destroy the Tree with a large ki blast, but it absorbs the energy instead. Fu then appears and confronts the group, informing them that he plans to create a new universe using the Tree. Xeno Goku, Xeno Vegeta, Xeno Trunks and Xeno Pan are suddenly teleported away by Fu's female companion, who is revealed to be Towa; she tells Fu that she is doing something for him, and then teleports away along with Majin Salsa and Putine. Vegeta powers up to Super Saiyan Blue and attacks Fu, but Fu reveals that he now has access to Cumber's energy and channels Cumber's aura through his own body, using its effects to corrupt Vegeta's ki and drive him berserk. Goku tries to intervene, but Fu corrupts his ki as well.

In Hell, Xeno Goku & Xeno Vegeta, even both as super saiyan 4, struggle against the reborn Janemba, who is aware of all of their abilities and tactics, which enable him to easily overwhelm both saiyans. Just when Janemba is about to finish them off, Xeno Trunks, Xeno Pan, Goku & Vegeta arrive in Hell through a wormhole, joining in on the fight. Xeno Trunks powers up to Super Saiyan 3, while Goku & Vegeta both power up to Super Saiyan Blue. Super Saiyan Blue Goku And Super Saiyan 4 Xeno Goku then team up and begin to overpower Janemba with their simultaneous attacks. But not long after, Putine & Majin Salsa arrive in Hell and knock back Janemba, enraging Dr. W by interfering in the fight.

Cumber unleashes his fearsome form and runs wild. His power is too much for the Prison Planet to handle, and the chains start to snap one by one. Seeing this throws Fu into a rage, and he unleashes his hidden power.
