The Neo Ginyu Force lead by Nappa attacks West City after being freed from Hell by Hell Fighter 17. Vegeta does not appear, and the Future Warrior confronts the Neo Ginyu Force instead along with GT Trunks, leading to the defeat of the Neo Ginyu Force. However, Hell Fighter 17 knocks out GT Trunks forcing the Future Warrior to face the Machine Mutant alone. However they are unable to stop Dark Hell Fighter 17 from fusing with Android 17, resulting in the creation of DarkSuper 17. Fortunately, GT Goku arrives and transforms into Super Saiyan 4. Fighting alongside the Future Warrior they manage to defeat Dark Super 17, though he is saved by Demigra's Wormhole.
During the fight with the Shadow Dragons, Pan, Giru, and GT Goku encounter Dark Nuova Shenron. The Future Warrior arrives to assist GT Goku, who asks them to go help out Pan who had chased after Giru when he detected another Dragon Ball, while he deals with Nuova. The Warrior finds Pan being confronted by Dark Eis Shenron. Eis Shenron is defeated, but Syn Shenron absorbs the other Dragon Balls and becomes Omega Shenron. Super Saiyan 4 Vegeta arrives and tells Pan to get back and joins forces with the Future Warrior in combating Omega Shenron. Soon Super Saiyan 4 Goku arrives and Vegeta suggests Fusion, leading him and Goku to fuse into Super Saiyan 4 Gogeta.
However, as they are about to defeat Omega Shenron they are sucked into Demigra's Wormhole and are confronted by Great ApeBaby, Super 17, and Omega Shenron, though the Future Warrior manages to destroy the Wormhole with some Ki Blasts. Eventually, Gogeta and the Future Warrior defeat the three villains. Xeno Trunks appears and tells Goku and his father that he will deal with returning the villains to their proper place in the timeline. Super Saiyan 4 Vegeta reveals he is happy and proud to see that his son from the other Future is doing well.
The Demon Android Mira arrives in Age 790 and places a Distorted Time Egg (one of Towa's failed attempts to recreate Tokitoki's Time Eggs artificially) near Majin Buu's House and yells at Buu when he enquires what he is doing before leaving. As a result, Majin Buu's House is involved in a large yet stable time rift anomaly which appears in Conton City. Chronoa sends Time Patrollers to Majin Buu's House to investigate the cause. The Majin Future Warrior is sent to investigate and they witness Majin Buu reading Bob & Margaret unaware of the rift surrounding his home and is visited by his friend Mr. Satan who is helping Majin Buu get settled. Majin Buu asks Mr. Satan about a word in the book he doesn't understand and Mr. Satan is shocked that Buu is reading such a book and asks him where he got it, causing Buu to reveal he got it from Mr. Satan's room. Mr. Satan tries in vain to get Buu to return the book, but gives up when Buu refuses and goes to fix dinner for his friend. The Future Warrior is called off for another assignment, but is later asked by Chronoa to return. The Future Warrior meets with Buu, who inspired by Mr. Satan's relationship with his daughter Videl, decides he wants a family of his own and enlists the Future Warrior in providing him with food to fuel his fission technique. As a result, in this timeline Miss Buu is not created and Majin Buu instead uses fission to create several children. Sensing the dormant power lying within the Majin Warrior, he assists them in unlocking their Purification Awoken Skill allowing them to access their Pure Majin form. He also shows them the Distorted Time Egg that the mysterious "pale man" had left near his home and gives it to the Warrior after they convince him not to eat it. After all the eggs are collected from the 5 rifts in Conton City, Chronoa decides to allow the rifts to remain in Conton City as they are stable and pose little threat. As a result, Majin Buu lives peacefully with his children and is occasionally visited by his friend the Future Warrior.
