Rage! Super Fu Appears!

Having defused back into Goku and Vegeta, Goku suggests cutting off Cumber's tail to revert him back to normal. As Cumber 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 Cumber'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. Vegeta and Future Trunks fire a volley of blasts at Cumber, but they do no damage to him. Even when Golden Cooler fires blasts of his own, Cumber is still unfazed. Meanwhile, Fu continues to watch the battle from his laboratory, smitten by the current events, until a nearby computer informs him of the damage to the Prison Planet's barrier and he decides to go to the battle himself to control matters. Goku still remains under the foot of Cumber, struggling to get free but is them seemingly crushed. However, Goku transforms into a Super Saiyan Blue and throws Cumber's foot off of him. Charging directly towards Cumber, Goku uses the Super Saiyan Blue Kaio-ken x20 and strikes Cumber 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 Cumber to watch what he's doing as he declares that he will rein him in. Fu powers up into an empowered state and gathers the energy from the artificial moon to his sword, before striking at Cumber and causing him to revert to his normal state. Cumber 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. Cumber powers up once more and Goku vows to take him on; he transforms into a Super Saiyan God, and Cumber appears to recognize it.
