Goku Black (LimitBreaker)

Goku Black is the main antagonist of the LimitBreaker Saga from Age 850. His true identity is Zamasu, a former North Kai and Supreme Kai apprentice serving the Supreme Kai of Universe 10, Gowasu, in which he stole the body of the original present Goku with the Super Dragon Balls and sought to destroy all mortals alongside Future Zamasu. His plans were however initially stopped by the likes of Goku and Vegeta, who had managed to seal Future Zamasu as well as subdue Goku Black with their new Divine Forms.

Background
This version of Goku Black originates from a timeline where the combined efforts of him and Future Zamasu allowed them to kill of the remainders of the resistance on Earth as well as Goku, Vegeta, Trunks, Gowasu and the Supreme Kai of Universe 7. He returns to Universe 10, in order to take the box of time rings, only to discover the existence of Chronoa, who had made attempts to communicate with the dead Gowasu. Frustrated by this, both Goku Black and Future Zamasu travelled across parallel universes to continue their Zero Mortal Plan after reaching the Time Nest and killing the Supreme Kai of Time, the latter lacking the time to power up to her Power of Time Unleashed Form.

When they had arrived in the LimitBreaker Timeline, they were surprised to discover that Trunks was in what would be considered the present at that time. Upon engaging combat, Goku Black was curious as to why Goku and Vegeta had merely powered up to Super Saiyan and not their Super Saiyan Blue forms. This in turn caused him to underestimate the pair, not knowing that they had tapped into divine Ki whilst remaining in their base Super Saiyan forms. Future Zamasu was taken by surprise and sealed away using the Mafuba (Trunks was told to grab it after discovering Zamasu was immortal). After this Goku Black was swiftly defeated and subdued. Goku, having fought against the present Zamasu not too long ago and understanding the hatred for mortals he possessed from his own twisted view on reality, had felt empathy for Goku Black and gave him the chance to redeem himself.

For a brief period of time, Goku Black had become non-hostile and seemingly started to have a change of heart as he spent more time around the Z-Fighters, especially after the Tournament of Power. However, as Zema returns to Age 780 to get to her wedding, Goku Black intercepts her and kills her on the spot, kickstarting the new Zero Mortals Plan known as "Project Null" on Torar and Zema's Wedding Day.

Power
All variations of Goku Black are the most feared enemy in the Time Patrol (2nd only to Yurmister after his attack) due to his immense power and, for this one particularly, seemingly invincible body. His power surpasses that of a God of a Destruction. It could be argued he's the strongest in the Time Patrol due to his pseudo-invincibility.
