Dragon Ball Super: "Future" Trunks Saga, vols. 2–5

Trunks returns from the future in a time machine, running from Goku Black, an enemy with Goku's face and body who is wiping out humanity in his era. Goku and Vegeta travel back with him to fight. The trail leads to Zamasu, a Supreme Kai apprentice from Universe 10 who despises mortals. Black is a Zamasu from another timeline who stole Goku's body with the Super Dragon Balls, and the future Zamasu joined him to become immortal. The two fuse with Potara earrings and the result nearly wins. Even beaten, Zamasu spreads across the future. Goku summons that era's Zeno, who erases the entire future. Trunks and Mai leave for another timeline, and Goku brings the future Zeno back to the present.
