At some point after the Universe Survival Saga, Goku and Vegeta are back to training with Whis on Beerus' planet. Future Trunks and Future Mai travel back in time and Future Trunks trains with Goku and Vegeta. Future Trunks is kidnapped and taken to the Prison Planet, so Goku, Vegeta and Future Mai head their to rescue him.
On the Prison Planet, Goku encounters another Goku, both Goku's see that the other possess a form that the other does not have (Goku with Super Saiyan Blue and Xeno Goku with Super Saiyan 4) and so they wish to see who is stronger, the two seem evenly matched but in the end Goku defeats Xeno Goku, who notes that Goku is a step above him. Goku questions Xeno Goku, but finds they are on the same side. Fu arrives and explains the situation and how to escape the Prison Planet - by obtaining the seven special Dragon Balls held by the prisoners.
Shortly afterwards they are confronted by the evil Saiyan Cumber. After Goku transforms into a Super Saiyan 2 and attacks Cumber, he loses all reason having come into contact with such evil ki and mutates into a Super Saiyan: Berserk where he then then begins to attack Vegeta instead. After Future Trunks arrives with Cooler, Cooler transforms to become Golden Cooler and with his new found strength defeats Goku with a single punch causing him to regain his senses. After Mai tosses him and Vegeta a pair of Potara, the two fuse to become Vegito in order to fight against Cumber.
After using up all their power in the fusion, they return to their individual selves only to see a Golden Great Ape Cumber standing in front of them. Goku attempts to battle it as a Super Saiyan but is quickly beaten and stepped on. In order to escape from being crushed, Goku transforms into a Super Saiyan Blue and proceeds to use the Kaio-ken X20 but the battle is interrupted by Fu who reverts Cumber to his normal state so he does not destroy the seal surrounding the Prison Planet. Cumber continues to attack Goku who now uses the form of Super Saiyan God but is still beaten and almost killed before being saved by Xeno Goku now with Xeno Vegeta.
Vegeta tries to wake up Goku to get all of them out of here when suddenly Goku reawakens into Ultra Instinct. With his counterpart in a stunned silence, Goku very quickly overwhelms and dominates Cumber. Goku looks at his counterpart before going back in to finish Cumber. Xeno Goku, knowing himself, asks everyone to grab onto him and uses Instant Transmission to teleport off the planet. Ultra Instinct Goku then defeats Cumber with a Kamehamaha. Before he can finish him, Fused Zamasu arrives and steals Cumber's body away, leaving Goku alone on the blowing up planet.
Universal Conflict Saga
Goku was saved by the Grand Minister, who brought Goku to Zeno's planet and gave him new attire that resembled his own. The Grand Minister takes him to Universe 11 where both his allies and his enemies are surprised to see him. Without saying as much as a word, he enters into his Ultra Instinct state and swats Oren, who is in possession of Vegeta's body, off of Future Trunks to save him. As Zamasu and Hearts make a remark on Goku's Godly power, an agitated Oren attempts to attack Goku but he is easily overpowered and unable to land a single attack. With a single punch, Goku is able to separate Oren from Vegeta and then blasts away an incoming Kamin. He then stares up at Hearts, prepared to face him next.
Goku hovers up to Hearts, confirming that he is the person he'd been told of when Kamin and Oren attack him in unison. Goku easily overwhelms them with his strength and reflexes and knocks them down again. After Kamin and Oren merge together to become Kamioren, Goku briefly battles the merged warrior until Hearts summon Rags who appears within a large pointed glass shard that Hearts sends towards Goku. Goku exerts all his strength in destroying the shard and reverts back to his normal state in the process. Rags then uses the broken smaller pieces to attack Goku and severely injures him to the point he falls down. Trunks saves him just in time from being hit by a vital attack but then manages to get into his fight to save Trunks though receives even more damage.
When Hearts sends Rags onward to Universe 3, Hearts vows to draw out Goku's true Ultra Instinct power. Goku transforms into a Super Saiyan and charges at Hearts but is immediately brought down by his Gravity Burst technique. Just then Shin teleports into the area and he and Goku teleport themselves, Trunks and Vegeta away.
They arrive in Universe 7 where Piccolo and Android 17 join up with them in order to battle the Core Area Warriors that appear. Goku transforms into a Super Saiyan and heads directly for Hearts but is once again repeatedly slammed to the ground via his Gravity Burst technique. After Hearts powers up, Goku gets to his feet ready for another round. Goku and Hearts begin fighting though he is forced backwards by a barrage of punches. With little other choice, Goku powers up further into his Super Saiyan Blue state.
Now able to compete with Hearts on equal grounds but is pushed back as Hearts comments that Goku's desire to fight can only be satisfied by him, which Goku rebuffs. The two acknowledge that neither is still using their full power. When the fight commences again, Goku turns the tides on him and overwhelms Hearts with a Kamehameha. However Hearts gets back on his feet and taunts Goku before using his Gravity powers on him. When Hearts uses his Gravity Fist technique, Goku is shown to be at a disadvantage as Hearts begins to power up even further. Hearts draws his energy cubes towards him and charges at Goku hard enough to send him to the ground and out of his Super Saiyan Blue form.
After Kamioren undergoes a transformation after merging with the power of the Universe Seed, Goku intervenes and stops one of Kamioren's punches aimed for Vegeta but is far overpowered and caught in his grip. After struggling to break free, he enters into his Ultra Instinct state once more and instinctively dodges Kamioren's punches and energy blasts. Kamioren fires a Mouth Energy Wave at Goku which he stops in its tracks and sends back at his enemy. As he brings his opponent down to his knees, Kamioren fires another energy wave but this time around is able to catch him.
Goku withstands the energy blast and emerges in his mastered Ultra Instinct state where he then proceeds to dominate the battle. When the other members of the Dragon Team launch an energy barrage at Kamioren, Goku fires off a powerful Kamehameha which causes the red bio-gem on Kamioren's chest to begin to crack. Goku charges forward and follows up with a strike to the gem which causes Kamioren to shatter into pieces. Exhausted, Goku reverts back to his normal state.
When Hearts is merging with the Universe Seed, Fused Zamasu appears to defend him. He takes down the entire Dragon Team with a single blow each but Goku manages to regroup himself and fights on, but unable to transform due to being exhausted of energy from recently using Ultra Instinct, he is at a disadvantage and Zamasu soon twists his arm around his back. He is saved by the appearance of Jiren and soon after Hit. The three attempt to take on Zamasu but are pushed back by a pulse from the newly completed Universe Seed.
Goku and the rest of the group prepare to face Hearts when he uses a collection of green orbs to attack and enclose the group in a tight space. Hearts takes Goku down with a single blow along with the others but as they get to their feet, Goku is the first to attack, transforming into a Super Saiyan Blue. However, his momentum is halted as Hearts tells him that he can see his movements and his heart before sending him flying backwards. After suffering through another onslaught, Goku suggests to Vegeta that they should fuse, not knowing when his Ultra Instinct may be available to him again. While his friends buy him time, Goku and Vegeta complete the process to fuse into Gogeta.
Gogeta eventually defeats Hearts and returns peace to the Earth. Jiren asks why they didn't fuse together during the Tournament of Power. Before Gogeta can respond, he defuses back into Goku and Vegeta individually. Vegeta finishes the explanation that it's because he never wants to fuse with Goku. Goku laughs off the comment, saying that next time he will deal with the enemy all by himself.
