Zamasu

Zamasu (ザマス), spelled Zamas in Viz Media's English localization of the Dragon Ball Super manga, is a fictional character and an antagonist in the Japanese manga series Dragon Ball created by Akira Toriyama. He is the first main antagonist of the sequel series Dragon Ball Super, who appears in various incarnations, first introduced as Goku Black (ゴクウブラック, Gokū Burakku) in the forty-seventh episode of the Dragon Ball Super anime series, which first aired on June 12, 2016, and in chapter #14 "An SOS from the Future!!" from the manga. Within the series, Zamasu is an apprentice Supreme Kai (界王神, Kaiōshin; lit. 'World King God') from Universe 10. In the series' original unaltered timeline, Zamasu hijacked Son Goku's body by using the Super Dragon Balls as part of "Project Zero Mortals" ("Zero Mortal Plan"/"Zero People Plan"). His plan is to attain supreme power and wipe out all mortal beings. He travels to an alternate future Earth and encounters the timeline's version of Trunks. Zamasu proceeds to bring humanity to the brink of extinction. To complete his plan, he joins forces with the future timeline's version of Zamasu, who is made indestructible. The character has been positively received and is regarded as one of the best villains/antagonists of the Dragon Ball franchise.
