I'll Settle This!! Activation! Ultra Instinct!

The Prison Planet has been destabilized by the destruction of the shield. Fu battles Xeno Goku and Xeno Vegeta, but their fight is interrupted when Cumber recovers and returns to the battle, attacking everyone on the field. Satisfied that he has achieved his objective, Fu opens a portal and escapes. Cooler pursues him through the portal before it closes, stranding everyone else on the Prison Planet. Cumber launches a massive energy blast at the group; Xeno Goku, Xeno Vegeta, Vegeta and Future Trunks attempt to block it, without success. Suddenly, Goku awakens, reawakens Ultra Instinct, and easily deflects Cumber's blast. Goku begins fighting Cumber again, while Xeno Goku teleports the rest of the group to safety. Goku overpowers Cumber and finally defeats him, knocking him unconscious with a Kamehameha. Five mysterious figures suddenly appear in the sky; one of them reveals himself as Fusion Zamasu, now wearing an eyepatch over his right eye. Zamasu collects the unconscious Cumber before the group teleports away, leaving Goku alone on the Prison Planet as it explodes.
