The evil Saiyan escapes his prison cell and attacks Goku, Vegeta and Future Mai. Goku and Vegeta attack the evil Saiyan, but his aura drives Goku berserk, causing him to attack Vegeta. Fu reveals that the evil Saiyan’s name is “Cunber”, and explains that his energy can turn people into a berserk state by just touching his aura. Goku continues attacking Vegeta; Future Mai is almost caught in the crossfire, but Future Trunks appears and saves her. Vegeta orders Future Trunks to fight Goku while he goes to battle Cunber, but he’s interrupted by Cooler, who now appears to be working with Future Trunks. Cooler begins fighting Goku and transforms into his own Golden form, which he calls “Golden Cooler”. Using this form, he defeats Goku, snapping him out of his berserk state and returning him to normal. Cooler then launches a Supernova attack at Cunber, but the evil Saiyan survives unscathed, breaks free of his restraints, and attacks the group once again. Future Mai reveals that the Supreme Kai gave her his Potara earrings before they left Beerus’ world, and gives them to Goku and Vegeta. Future Trunks and Cooler distract Cunber, who easily defeats Future Trunks; however, this gives Goku and Vegeta enough time to fuse into Vegito. Vegito powers up to Super Saiyan Blue and prepares to fight Cunber.
