Dragon Ball Super: Season 4, Episode 7

4 - 7: Expose Black's True Identity! To the Kaioshin Realm of Universe 10

Goku, Beerus, and Whis arrive on the Tenth Universe's World of the Kais (界王神界, Kaiōshin Kai) where they meet the resident Supreme Kai Gowasu (ゴワス) and his apprentice Zamasu (ザマス), who expresses a disdain for mortals. An excited Goku challenges Zamasu to a sparring match, the Kai objects until Gowasu allows it with Beerus advising him to not hold back. Zamasu is baffled at being outmatched against Goku while Beerus and Whis note the Kai's energy being similar to Goku Black's, with Zamasu having no recollection of meeting Goku, and that the Time Rings in Gowasu's possession are accounted for. Goku, Beerus, and Whis return to their universe, unaware their actions only strengthened Zamasu's ideology. On Earth, Krillin introduces Future Trunks to his family, with Android 18 teasing Trunks due to his history with her alternate future self.
