Zamasu was a kai and the main antagonist of the Future Trunks Arc. Zamasu was a Kai that served under Gowasu and once respected his master. Zamasu grew distrustful of humans and mortals after losing in a figth against Goku. Zamasu wanted to eradicate all mortals across the universe and teamed with a counterpart of himself called Goku Black to complete the plan.
Zamasu was once a good person who respected his master Gowasu. Because of his distrust and suspicions of mortals, Zamasu hated the mortals and wanted to destroy them. He soon developed a hypocritical and supremacist mindset where he thought himself to be supreme to any mortal because he was a kai and that humans were inferior to him. All other incarnations of Zamasu share the same mindset when it came to his views on mortals and humans.
After losing in a fight to Goku, Zamasu became distrustful of mortals and slowly began to embrace his dark side. He would try to betray his master Gowasu by trying to murder him for the time ring. When confronted about his plan, Zamasu was gleeful of its success and thought that he could not die. Present Zamasu expressed delight at hearing about success of his Zero Mortal Plan.
