Super Dragon Ball Heroes

Goku and Vegeta's training with Whis and Beerus is interrupted by the arrival of Future Mai, who tells them that Future Trunks has been captured. A mysterious figure emerges, introducing himself as Fu; he tells Goku, Vegeta and Mai that Future Trunks is trapped on a world called the "Prison Planet", a planet where warriors from alternate timelines and dimensions fight as part of an experiment conducted by Fu. The trio arrive on the planet and meet an alternate version of Goku called "Xeno Goku", who transforms into Super Saiyan 4 and attacks Goku, who reacts by transforming into Super Saiyan Blue. During the fight, Goku discovers that there is an invisible barrier around the Prison Planet that prevents them from escaping. Then Fu disappears, and the two Goku agree to work with each other to escape the planet. In the end, Fu observes the Prison Planet and tells a seemingly evil Saiyan that his time will come.

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

In the Time Nest, headquarters of the Time Patrol, the Supreme Kai of Time informs Xeno Trunks and Xeno Pan that her mystical bird Toki-Toki has disappeared. She sends the two of them to find him, while also being worried about a supposed "Bird of Catastrophe" that has been released. Meanwhile, Toki-Toki has appeared on Earth in the main timeline, where Goku finds him while training with Vegeta, Gohan, Piccolo, Krillin, and Android 17. Xeno Trunks and Xeno Pan arrive and are happy to see that Toki-Toki is safe, with Xeno Pan explaining that his existence is very important for the inner workings of the multiverse. Suddenly, the group is interrupted by the arrival of all twelve Gods of Destruction.

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.

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.
