"YES! I know wishing to become an intergalactic superstar might seem a bit weird and a little, you know... selfish, but it was to stop your evil. And honestly, I'm kinda excited about it!"
Dragon Ball Super
While not appearing physically, Mr. Satan asks Future Trunks if his future self saved the world in the Future timeline during the "Future" Trunks Saga. It is unknown if he was killed by the Androids, Goku Black, Infinite Zamasu, or when Future Zeno erased the timeline.
While the Dragon Team and Future Babidi are on New Namek, while running away, Future Mr. Satan falls on the ground due to a pebble on the ground. Future Mr. Satan then meets Future Innocent Buu and gives him the pebble for a present. Then, they start playing together, however Future Dabura sees Future Buu playing with Future Mr. Satan and launches an attack at Future Mr. Satan. This causes Future Majin Buu to become more enraged than he has ever been, his mists coalesced and forms a new Buu. The new, thin Buu turns the tables and the fat Buu ends turned into chocolate. The thin Buu eats him, and changes into a new and far more powerful form, Future Super Buu.
Later, while Future Babidi is attempting to have his wish granted by Shenron, he is cut off by Future Mr. Satan who wishes to become the most popular guy in the universe, this to stop Future Babidi's evil. Enraged at having his wish stolen, Future Babidi lashes out at Future Mr. Satan, but Future Super Buu takes the blow instead, leaving him near death. Future Babidi desperately tries to revive Future Super Buu but once revived, Future Super Buu eats Future Babidi for his treachery. Upon gaining Future Babidi's power, Future Super Buu changes form and achieves his pure form, Future Kid Buu.
- Technically, Future Mr. Satan is the intergalactic superstar.
- In Dragon Ball Xenoverse 2, if Future Gohan is the Future Warrior's current instructor, Mr. Satan will ask about the fate of his future counterpart's daughter, Future Videl and if Future Gohan has any kind of relationship with her.
