Dragon Ball: Redemption in the Future

Dragon Ball: Salvation of the Future tells the story of Future Trunks transmigrating to the past and joining forces with the Z Fighters, using his knowledge of the future to rewrite their fate. They first thwart the invasions of Raditz and Vegeta, then battle on Planet Namek and defeat Frieza, before teaming up with another version of himself from a different timeline to finish off Frieza and his son. When they face Cell, everyone breaks through to the pinnacle of Super Saiyan 2.

Then Vegito and Gohanks emerge, transmigrate to the GT world and master Super Saiyan 4, before entering the Dragon Ball Xenoverse and learning Super Saiyan God and Super Saiyan Blue, eventually touching the realms of Ultra Instinct and Ultra Ego. They fight in the World Martial Arts Tournament spanning all universes, defeat Black Vegito, and join forces with warriors from across the universes to overcome the God of Nothingness and the Chaos Entity. They even break through to Super Saiyan 5 in the AF timeline.

In the end, Vegito fuses with a Gogeta from another timeline to become Super Saiyan 6 Gogeta, purify the evil Zeno, and become the “Guardian Who Surpassed Zeno.” After countless adventures across spacetime, the Saiyan warriors finally return to their peaceful daily lives. They turn their belief in protecting others into a cosmic epic, continuing the legend of the strong in the quiet that follows.
