Dragon Ball Super S04E21 - A Visit from the Omni-King! Bye-Bye Zamasu!

The bifurcated Merged Zamasu expresses his disbelief of being defeated as he disintegrates, the victory short-lived as Zamasu transcended his physical form and is now merging himself with the universe. Infinite Zamasu wipes out everyone on Earth with only Goku and company remaining while proceeding to bleed himself into all space and time. Goku looks for another Senzu bean in his pocket when he instead finds the button that Zeno gave him, summoning the future timeline's Grand Zeno. After Goku explains the situation, Future Grand Zeno erases the future multiverse with the Supreme Kais returning to the past while Goku and the others escape using the Time Machine as Zamasu ceases to exist. Once the group return to the present, Goku and Future Trunks return to what remains of the future timeline to retrieve Future Zeno. Goku then has Shin take him and Zeno to give him Future Zeno as the promised playmate with the Grand Minister (大神官, Daishinkan) expressing astonishment to his son Whis. Whis later suggests Future Trunks and Future Mai to travel to a point in their timeline before Zamasu became a threat where he can be removed by Beerus, though it would mean they would co-exist with the new timeline's versions of them. Future Trunks and Future Mai accept the solution and depart for the new future.
