"Evil is violence like that of the Babarians and conceit like that of Son Goku, who would trade blows with the gods. Humans use their god-given wisdom for evil and spoil our beautiful world. The humans who have gained wisdom are true evil. Does this not strike you as half-hearted? What good are gods if they do not destroy evil?!"
Zamasu was the Supreme Kai apprentice serving the Supreme Kai of Universe 10, Gowasu. He was formerly the North Kai of Universe 10.
Zamasu was an average height individual. He had pale green skin and white hair in the style of a mohawk. He wore a purple shirt under a gray and yellow coat, a light blue sash, darker blue pants, and white boots. He also wore orange earrings that were similar of the Potara.
Generally, Zamasu is shown to be a very calm and methodical person, as shown in combat when carefully perceiving his opponent's attack style and seamlessly countering in a fluid manner. While a man who cares for the development and prosperity of the universe, Zamasu often questioned the worth of mortals, not trusting in their ability to handle conflict as they were prone to commence war in a repeated cycle. He also did not agree with how the Kais would not be more directly involved in mortals' actions like the Gods of Destruction. In the manga, his views on mortals are even shown to scoff at the idea that mortals can be trusted to handle important matters, let alone rival the might of gods.
Despite this, he acknowledged his lack of personal experience and was willing to diligently listen to his teacher Gowasu's words, to which, he was a humble and level headed man with just goals, as Gowasu noted by how well-balanced he would brew tea, implying that he was a just man. After meeting Goku however, his views radically changed and his distrustful nature towards mortals only grew. Annoyed at Goku's carefree attitude and lack of respect, his distaste for the gods not quelling the dangerous nature of mortals evolved to a radicalism-level. Shocked at how a mortal like Goku could gain a power rivaling gods (even obtain such power) and so recklessly challenge one, Zamasu came to sternly believe that mortal life by nature is an evil.

Zamasu is first seen carrying a cart of refreshments. He then gives a cup of tea to his master, Gowasu. His master then tells him about his duties as a Supreme Kai, which is watching over their universe including mortals. Zamasu then asks him if the mortals are worth their protection, due to their past mistakes. Gowasu explains that the Supreme Kais' and Kais' duties are to create and not interfere with creations. Zamasu implores if Gowasu is telling him to look past the mistakes of mortals with Gowasu simply telling him to know his place, watch over and raise them. Zamasu is silent and reluctantly accepts the situation when Gowasu repeatedly implores for a response from him.
Beerus, Whis, and Goku then show up with the latter repeatedly asking Zamasu to fight him, but is then stopped by Beerus. They then tell them about someone who is similar to Goku and how he has a Time Ring. Beerus asks to see the Time Rings. Shortly afterwards, Zamasu reluctantly fights Goku after Gowasu instructs him to do so, stating that it's part of Zamasu's training. Goku turns into a Super Saiyan 2, much to Gowasu's and Zamasu's surprise. During their battle Goku, Whis, and Beerus feel Zamasu's ki, saying it is very similar to Black's. Goku then overpowers Zamasu, defeating him in battle. Goku offers his hand but Zamasu reacts with hostility before being reprimanded by Gowasu. After they leave, the fight only furthers Zamasu's hatred for mortals, now thinking they are dangerous. However, Goku notes his ki is not quite the same as Black's. However, Whis is convinced that Zamasu and Black are in fact the same person not only due to their Ki but the fact that he felt the same coldness in his heart that he felt from Black.
Zamasu and Gowasu become aware of creatures on the planet Badari while sitting for tea. Zamasu advocates for the destruction of the creatures, only to be rebuked by Gowasu who asserts that it is the place of the God of Destruction to carry out that act and not his. Gowasu then shows Zamasu the Time Ring, explaining its function to him and Zamasu also learning that one cannot travel back to the past with them. Gowasu prepares for the two to depart to the future of Badari though mentions that Zamasu cannot go since he is only an apprentice and not a Supreme Kai, before passing Zamasu an earring and allowing him to be one for the time being. Zamasu puts the earring on the ear corresponding to Gowasu's to ensure the pair do not fuse and denies interest in merging with him for the time being. The two fist bump and say "1000 years", transporting into the future of Badari where a fight breaks out between the planet's denizens, Zamasu concluding their continued existence would ensure no peace.
Observing the Babarians with Gowasu, Zamasu views them as accomplishing goals with brute force and a disregard for laws or justice. A Badari attacks them, Zamasu repelling it a short distance away from them with his hand and goes against Gowasu's wishes by slicing the creature in half, killing it. Returning to their planet, Zamasu returns the earring to Gowasu upon the latter’s request and later prepares tea, rebuking his mentor’s claim that they can learn from mortals, instead reasoning that they cannot learn given the example the Badari set. Gowasu tries explaining justice is meant to counteract evil but Zamasu forwards that mortals have used knowledge to dirty their world and that the ones with knowledge are evil. Gowasu warns that he must calm himself and that the Gods should also learn, Zamasu leaving to fetch Gowasu more tea and thinking non-interventionism is a crime.
Later, while watching the fight of Universe 6 and 7 tournament on God Tube with Gowasu, Zamasu sees the Super Dragon Balls. Zamasu, curious to why the Gods of Destruction would be fighting over the Super Dragon Balls, asks Gowasu what they are. Gowasu explains to Zamasu that they are orbs that can grant any wish, much to Zamasu's surprise. Also while watching the tournament, Zamasu sees Goku covered in godly Ki and much to his anger as he wonders how mere mortals could achieve this kind of power. He heads to Zuno's place and asked them to know more information about the Super Dragon Balls and Goku, which a flustered Zuno complies to.
Later, Zamasu re-appears in Universe 10 with Gowasu's tea, apparently calm despite the appearance of Goku, Beerus, Whis and Supreme Kai.
Zamasu apparently manages to see off his guests and reunites with Gowasu. After confirming their suspicions of Zamasu's true intentions, Goku, Supreme Kai, Beerus and Whis head out to protect Gowasu and make him realize Zamasu's currently evil nature. Though shocked by how much they know about what he thought and planned, he is undeterred and attempts to attack Goku with an energy blade. However, Beerus intercepts him and destroys him afterwards, putting an almost instantaneous end to the once prodigious Supreme Kai apprentice. Gowasu speaks his name as he seemingly laments that his apprentice had to die to learn of his wrong ways.
Zamasu is recognized as a genius among the Kais with a prodigious talent for fighting, with Goku remarking that his power surpasses that of Universe 7's Supreme Kais. In the manga, East Supreme Kai even noted that Zamasu had greater skills and abilities than any of the current Supreme Kai from each universe. This is proven when Zamasu easily out-maneuvers Kibito in their match, being interrupted from landing a serious blow due to Gowasu claiming the match was over. In the anime, when he was fighting with Super Saiyan 2 Goku, he is shown to be able to carefully intercept his punches. Ultimately he struggles in his battle with him and is surprised by Goku's power, which Gowasu remarks as being that of a god. In the end Goku overpowers Zamasu with his strength and defeats him. Goku says that Zamasu may be able to become as strong as Beerus one day, though Beerus scoffed at the notion, claims that his capacities are on an entirely different level. This is proven when Beerus effortlessly intercepted Zamasu's attack and destroys him instantaneously.
