Editing Crimson-Masked Saiyan (section)

===Background===
Crimson shared the same backstory as Goku Black until a critical intervention by Fu. Fu contacted Crimson and revealed the constraints of his current trajectory, warning him of his eventual defeat due to the limitations of his body. He also provided Crimson with a Time Breaker Mask. To avoid this doomed future, Crimson diverged from his original path by traveling across various parallel timelines instead of collaborating with Future Zamasu.

In these timelines, Crimson faced and defeated 99 different versions of Goku, including those who had achieved formidable transformations such as Super Saiyan 3, Super Saiyan God, and Super Saiyan Blue in the anime. Notably, in the manga, he even fought against the 86th Goku, who had attained Ultra Instinct Sign. Through these battles, Crimson aimed to fully master his stolen body and unlock its ultimate potential.

During this period, it was also revealed that Crimson had resumed Project Zero Mortals, systematically exterminating all mortal life in multiple timelines. Furthermore, he used Fu's assistance to his advantage, manipulating Fu to further his own agenda, which possibly included acquiring the Time Breaker Mask. Eventually, Crimson entered the Pseudo Universe once it was created, while Fu found himself trapped in the Time Labyrinth alongside Xeno Vegito.
