Editing Goku (Dragon Ball Heroes) (section)

====New Space-Time War Saga ====
In the anime, after Fu creates his new universe, Goku awakens alone in a strange and eerie alternate version of West City on Earth, wondering what is going on. He is attacked by the Frieza Force including Frieza and Meta-Cooler while trying to escape from Fu's Universe. He teams up with Hearts to fight the Golden Brothers, using Ultra Instinct Sign to fight and quickly overwhelm Frieza before returning to his base form. However, the galactic tyrants are given a burst of power when they unexpectedly find themselves merged with a Dark Dragon Ball. The two brothers are able to pressure Goku and Hearts until Broly arrives on the scene and takes down everyone with ease.

After Broly takes off after the Warrior in Black and the Crimson-Masked Saiyan leaves. An exhausted Goku sits on the ground and Hearts tosses him a Senzu Bean. Goku recovers and thanks Hearts as he brings out the Four-Star Dragon Ball and tells Goku that if the Senzu Bean still had the same effect in the Space-Time then the same should be true for the Dragon Balls. The two decide to collect all the Dragon Balls and use them to escape. They head to Capsule Corporation where Goku collects the Dragon Radar. Turning it on, he picks up two signals, one of which belongs to Hearts and the other up above them.

Goku teleports himself and Hearts to Planet Vegeta. There, the Crimson-Masked Saiyan arrives and informs Goku that he is his opponent before transforming into a Super Saiyan Rosé. Goku realizes that this is indeed Goku Black, revived through unknown means. Black proclaims that he will defeat his original counterpart and prove himself to be superior. Goku goes Super Saiyan Blue and the two fight, with Hearts following them after transforming into Super Hearts. However, Goku Black defeats the two, holding the former by the neck and swiftly tosses him aside.

However, Goku unexpectedly returns and appears behind the Crimson-Masked Saiyan in his Ultra Instinct Sign state. The Crimson-Masked Saiyan blasts Goku at point-blank range, though it causes no damage to him. Goku proceeds to avoid every one of his opponent's attacks and appears to have the advantage in battle. The Crimson-Masked Saiyan takes to the skies and fires a couple of energy blasts to leave Planet Vegeta on the verge of destruction.

Goku attempts to use Instant Transmission to escape but is unable to as he cannot sense any other ki signatures. However, much to everyone's surprise Cell appears and teleports everyone away just in nick of time. Goku asks Cell how he was able to come back though Cell simply says it is just the same as how Hearts was able to. Vegeta asks why he decided to save them, but Cell tells them to be patient and hear what he has to say. Two other figures then appear behind the group with Goku and Vegeta surprised at their identity.

Goku and the others join Gohan and his group in a nearby cavern and shortly afterwards Shroom appears along with Salsa and Putine and explains that Cell is lending a hand in taking the Crimson-Masked Saiyan. With a powerful enemy to face and Goku not having yet mastered Ultra Instinct, Shroom and the other demons open up a doorway to a room similar to that of the Hyperbolic Time Chamber. Goku and Vegeta go inside where they face phantoms in the guise of enemies from the past and seemingly complete their training in time, leaving the room and making their way to West City to face the powered up Super Saiyan Rosé 3 Crimson-Masked Saiyan.

Together with Vegeta, they overpower their foe with Goku landing a mighty foe that sends his opponent hurtling into a building, shortly afterwards Goku's Ultra Instinct state runs out. However, the Crimson-Masked Saiyan enters into his Super Saiyan Rosé Full Power state and Goku and Vegeta are left with no choice but to fuse into Gogeta once again. Gogeta successfully defeats the powerful adversary and defuses. The Warrior in Black re-appears carrying the full set of Dragon Balls which he uses to send everyone out of the Pseudo Universe.

Goku finds himself back in the Crack of Time where he encounters a younger looking Fu who has absorbed Dogidogi. When Vegeta appears, Goku fuses him with again to become Gogeta and fights along Xeno Gogeta but the two are quickly overpowered and defuse. Fu then throws the Vegeta's into a dark vortex to prevent further fusion, but the Goku's receive some unexpected backup in the form of Chronoa. Chronoa heals the pairs injuries and asks that the two power up to their limit. She then performs a technique that allows the two Saiyans to merge their Ki together. They attack with a combined Kamehameha, which breaks through all of Fu's barriers, forcing him to block it himself. Despite Fu stating the attack was dangerous, Xeno Goku notes that, even with this immense power, he and his alternate self are still unable to beat the Dark King.

Fu begins absorbing power from the Universe Tree, and to an extent, all of the universe itself. When Fu attacks tries to attack Chronoa, Goku grabs one of Fu's tendrils and rips it off. The energy given off by the tendril at first begins to overwhelm him, but Goku manages to harness it for his own by also harnessing the Universe Tree's power to gain Super Saiyan God Super Saiyan (Universe Tree Power). Goku and Fu two engage in an epic battle, climaxing with a powerful beam struggle that ends with Goku managing to finish him with a Kamehameha. Fu finds it impossible that the universe has so much potential, and with those seemingly being his last words, he is defeated with a smile on his face.

After the battle, Goku is sent back to where he came from after Toktoki uses his power to restore Universe 7.
