Having defused back into Goku and Vegeta, Goku suggests cutting off Cunber's tail to revert him back to normal. As Cunber fires yet another blast at the Saiyan pair, Goku and Vegeta avoid it and fly directly upward, transforming into Super Saiyan in the process and attempt to get to Cunber's tail but even at his great size he proves to be swift enough to defend himself. As he steps on Goku, Future Trunks rushes in to help and tries to cut off the Golden Great Ape's tail with his sword but is struck hard to the ground. Along with his father, they fire a volley of blasts though they do no damage to him. Even when Golden Cooler fires blasts of his own, Cunber is still unfazed. Meanwhile, Fu continues to watch the battle from his laboratory, smitten by the current events when a nearby computer informs him of the damage to the Prison Planet's barrier and decides to go to the battle himself to control matters. Goku still remains under the foot of Cunber, struggling to get free but is them seemingly crushed. However, Goku transforms into a Super Saiyan Blue and throws Cunber's foot off of him. Charging directly towards Cunber, Goku uses the Super Saiyan Blue Kaio-ken x20 and strikes Cunber in the face though he is unmoved. Goku fires a Kamehameha though the move is blocked. The ongoing battle causes the barrier to break down even more when suddenly Fu arrives, telling Cunber to watch what he's doing as he declares that he will rein him in. Fu powers up into an empowered state and gathering the energy from the Power Ball to his sword, he strikes at Cunber which causes him to revert to his normal state. Cunber throws a punch at Fu but he easily avoids it. While the others comment on what he just did, Fu tells them to continue their battle as he teleports away, avoiding Cooler's blast in the process. Cunber powers up once more and Goku vows to take him on as he transforms into a Super Saiyan God as Cunber appears to recognize it.
