Super Dragon Ball Heroes

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. Goku tries to find a way to escape, but he is tracked down and attacked again by Frieza and Cooler. However, Hearts appears and rescues him. Goku is shocked, but Hearts explains that Demigra pulled his spirit body out of Hell, and that he wants Goku to help him destroy Fu for misusing the Universe Seed. Goku and Hearts form a tentative alliance against Frieza and Cooler, who both transform into their Golden forms. Hearts battles Cooler, while Goku briefly taps into Ultra Instinct and uses its power to subdue Frieza. However, a mysterious masked Saiyan with hair similar to Goku's appears and implants two red Dark Dragon Balls into Frieza and Cooler, granting them a significant powerup.

Goku and Hearts struggle against the newly-empowered Frieza and Cooler, until their battle is interrupted by the arrival of the alternate Broly in his Legendary Super Saiyan form. Broly attacks all four combatants, overpowering them all, as the masked Saiyan looks on. Suddenly, a mysterious cloaked figure arrives on the scene and attacks both Cooler and Frieza, removing the Dark Dragon Balls from both of them. Broly attacks the cloaked figure, who leads him away. Hearts reveals that he is unable to read the minds of either the cloaked figure or the masked Saiyan, who teleports away. Hearts gives Goku a duplicate Senzu bean to heal his injuries, and reveals that duplicates of the normal Dragon Balls also exist in this universe. Goku theorizes that if they gather all of the duplicate Dragon Balls, they may be able to use them to escape. Using a duplicate of the Dragon Radar, they track one of the other Dragon Balls to a nearby planet. On that planet, the masked Saiyan observes Vegeta, Turles and Cumber, and orders them to begin fighting each other.

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 Goku Black; he powers up to Super Saiyan Rosé and begins fighting Goku. Turles tries to corrupt Vegeta's ki using the evil energy that he absorbed from Cumber, but Vegeta is able to resist the effects of the corruption and absorbs the dark energy for himself. Using this newly-enhanced strength, Vegeta easily defeats Turles and then knocks Cumber unconscious with a Gallick Gun. He advises Turles to leave and train before challenging him again, but is then horrified to see that Black has overpowered Goku and Hearts.

Vegeta intervenes to protect Goku, but his new power runs out before he can deal with Black. Black reveals to Vegeta that he is an alternate version originating from before he was destroyed by Future Zeno: Fu told Black about his future, which prompted him to study Goku by fighting versions of him in 99 other timelines. Just before Black can kill Vegeta, Goku taps into Ultra Instinct and quickly overpowers Black. However, Black fires an energy blast into the planet, destabilizing it. Goku tries to teleport the others to safety, but is unable to do so. Turles returns and attacks Black, but is swiftly defeated and is seemingly killed. Suddenly, Cell appears (also in a spirit body) and saves Goku, Vegeta, Hearts, and the unconscious Cumber. Black also teleports away before the planet explodes. Goku and Vegeta interrogate Cell, who explains that he was pulled out of Hell by Demigra for the same reason as Hearts. Before Cell can explain the situation further, several mysterious figures appear that shock Goku and Vegeta.

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. Cell secretly vows to get his vengeance on the Z-Fighters for killing him; Hearts reads his thoughts, but doesn't say anything to the others. Goku explains that he and Vegeta could defeat Black with Ultra Instinct and with Vegeta's new power, but that neither of them can properly control those powers yet. Shurum, Majin Salsa, and Putine open a portal to a pocket dimension similar to the Hyperbolic Time Chamber, which will give Goku and Vegeta some time to train and master their new powers. Shurum assures them that he has another partner who will keep Black occupied while they are training. Goku and Vegeta enter the pocket dimension, where they are confronted by shadowy duplicates of some of their past enemies. Elsewhere, Black observes the new universe, until he is ambushed by the cloaked figure from earlier, who reveals himself as a powerful Super Saiyan. The others prepare to go and help, but they are intercepted by Bojack, Super Android 17, and Dr. W, who reveals himself as Dr. Wheelo. Black powers up even further into a form resembling Super Saiyan 3 and defeats the cloaked Super Saiyan, but he is interrupted by the arrival of Goku and Vegeta, who have completed their training and mastered their full powers.

The cloaked Saiyan teleports away as Goku and Vegeta overpower Black; however, Goku drops out of Ultra Instinct, and Black powers up to his full strength by using his mask to absorb more energy from the false universe. In this new state, he swiftly defeats Vegeta. Frieza and Meta-Cooler arrive in their Golden forms and challenge Black, but he uses a mystical scroll to summon a Majin-powered version of Omega Shenron, who easily defeats them. Hearts and Cumber arrive and battle Omega, while Black makes short work of Frieza and Meta-Cooler: however, Goku and Vegeta use the opportunity to fuse into Gogeta and power up to Super Saiyan Blue. Gogeta and Black begin fighting, and Gogeta appears to have the upper hand until Black uses his mask's power to heal his injuries and continues powering up by absorbing more energy. Gogeta then powers up to his own maximum by accessing Super Saiyan Blue Evolved and easily defeats Black, finishing him off by shattering his mask. The destruction of Black's mask causes him to disintegrate, and Omega disappears along with him. The cloaked Saiyan then returns, having used the time the others bought him to assemble all seven of the false universe's Dragon Balls. He activates them, and Goku is suddenly teleported back to the Universe Tree, where he encounters a younger version of Fu.

Fu reveals that his new, youthful appearance is a result of his merging with Doki-Doki, which allowed him to break free of Demigra's Time Labyrinth. Goku is joined by Vegeta, Xeno Goku, and Xeno Vegeta, the latter two having also escaped from the Time Labyrinth. The alternate Broly arrives and attacks the other Saiyans, but Hearts and Cumber arrive to intercept him. Goku and Vegeta fuse back into Gogeta, while Xeno Goku and Xeno Vegeta fuse into Xeno Gogeta; they then power up to Super Saiyan Blue Evolved and Limit Breaker Super Saiyan 4, respectively, before challenging Fu. They have the advantage at first, until Fu powers up even further and hits them with a massive ki blast that forces them to defuse. Fu then teleports both Vegeta and Xeno Vegeta away, preventing the Saiyans from fusing again, before preparing to destroy Goku and Xeno Goku. The Supreme Kai of Time suddenly appears and saves the two Gokus from another blast, before using her powers to help them combine their energies. The two Gokus power up to maximum and their energies merge together, giving them a massive power boost as they prepare to battle Fu again.

Fu tries to shield himself with an energy barrier, but the two Gokus blast through it and land a powerful hit on him: however, he survives unscathed. Fu begins draining energy from the Universe Tree to power himself up even further. Goku blocks one of Fu's attacks when he tries to kill the Supreme Kai of Time, but the Tree's energy begins overwhelming him: however, he's able to use his Spirit Bomb technique to absorb the Tree's energy for himself, cutting Fu off from it. Using the Tree's power, Goku gets the upper hand against Fu, and they engage in a final beam-clash. Thanks to the Tree's energy, Goku is able to overpower Fu's blast, and the resulting explosion kills Fu and drains all the remaining energy from the Tree, destroying the fake universe. Toki-Toki returns with the two Vegetas, while Hearts also returns and reports that both Cumber and Broly have disappeared. With Fu defeated, the Supreme Kai of Time uses Toki-Toki's power to repair the damage done to the multiverse. Elsewhere, the cloaked Saiyan reports back to his master, a mysterious alien woman, who claims that her time has come.
