Zamasu was the North Kai of Universe 10, as well as the Supreme Kai apprentice from Universe 10, and is also the main antagonist of the "Future" Trunks Saga in Dragon Ball Super. Due to the abuse of time travel and taking up of new forms, several different incarnations of Zamasu exist:
- Zamasu, the Zamasu that originated from the Altered main (present) timeline. He was destroyed by Beerus.
- Goku Black, the original present Zamasu from the original, Unaltered Main (present) timeline. In the original present timeline, the Z Fighters were unaware of the existence of the original present Zamasu or his growing hatred for mortals, so this Zamasu was not destroyed by Beerus. He used the Super Dragon Balls to switch his body with the original present Goku's body, then he went to Future Trunks' timeline using his Time Ring.
- Future Zamasu, the Zamasu from Future Trunks' timeline, who used the Super Dragon Balls to become immortal.
- Fused Zamasu, the fusion between Goku Black and Future Zamasu, created by a Potara fusion, or alternately the fusion of Goku Black and Present Zamasu from the altered main timeline in Dragon Ball Fusions, also created by a Potara fusion.
- Infinite Zamasu, the final incarnation of Fused Zamasu, this entity is the embodiment of his will, or his mutated form in the manga, attempting to become one with the universe.
- Zamases, different incarnations of Zamasu that have grouped together from multiple timelines.
