Goku Black arrives in the past. Future Trunks decides to fight Goku Black, but Vegeta stops him. Curious to know how powerful Goku Black really is, Goku decides to fight him. Neither of them seems to be particularly interested in their fight. Goku decides to transform into a Super Saiyan. Goku Black proves to be no match for powered-up Goku. Future Trunks wonders why Goku does not simply destroy his opponent. Goku Black tries to power up but before he is able to, Goku thwarts him. While Goku and Goku Black fight, the time portal starts to disappear.
It also starts dragging Goku Black towards itself. Goku Black realizes this. He destroys the Time Machine as soon as he had been dragged into it, which prevents others to return to the future. With Goku Black suddenly gone, Goku wonders where his enemy could have disappeared. Whis explains that Goku Black used a time-traveling method only Kaiō-shin know about. Bulma decides to search for the other Time Machine that Cell used to travel back in time. Just as Goku Black reappears in the future timeline, Mai regains consciousness.
