Dragon Ball Super: Season 4, Episode 8

4 - 8: He Who Carries Saiyan Blood Trunks' Determination

While Bulma and her team put the finishing touches to the rebuilt Time Machine, Vegeta decides to test Future Trunks' power to see how strong his son had become and overpowers him in Super Saiyan Blue form. Vegeta is vexed over Future Trunks being content with him and Goku being strong enough to defeat Goku Black, telling his son that Saiyans should continually strive to grow stronger to always prepare for an enemy. On Beerus' planet, Beerus and Whis are about to eat dinner when Zeno contacts them with a request to see Goku. In the Tenth Universe, Gowasu attempts to have Zamasu reconsider his views on mortals by temporary promoting him to Supreme Kai and use a Time Ring to observe the progress of a new race on Planet Babari (惑星ババリ, Wakusei Babari) within a millennia's time.
