After a reunion with a now adult Gohan, Trunks becomes encouraged to defeat Goku Black in order for the people of his own timeline to have a chance at that same happiness, also having a reunion with a reformed Android #18. Trunks then receives training from Vegeta, vowing to surpass both his father and Goku Black in strength.
