Future Zamasu (のザマス 'Mirai no Zamasu') is an alternate timeline counterpart of the Zamasu from Future Trunks' timeline. He is the secondary antagonist of the "Future" Trunks Saga. He is the former Supreme Kai apprentice of Universe 10, who became a Supreme Kai. This version of Zamasu is an ally to Goku Black (his past self from the original present timeline) and the two were the only "gods" left in that timeline.[2] He along with Black worked together to wipe out all Mortals with Project Zero Mortals.
