On Beerus' Planet, Goku and Vegeta continue their training, still attempting to land as much as a single blow on Whis but fail to do so.

Fu talking about the Prison Planet

From behind Mai, another being appears introducing himself as Fu. While Goku and Vegeta are unfamiliar with who Fu is, he in turn knows who they both are, having been told about them by Trunks previously who he refers to as his friend. Shin asks if he is from the future also and Fu confirms that he is before telling them all that Trunks has indeed been kidnapped and is currently imprisoned on the Prison Planet, a place that does exist in the present timeline. Fu opens a space time portal using his sword as Goku and Vegeta prepare to head through and rescue Trunks.

Shin attempts to stop them and seeks backup from Whis, however Whis mentions that it is now time for him to go and wake up Beerus who will surely be angry once he hears the news of Mai and Fu breaking galactic law by using time travel and tells the others to make sure that the pair return to their own time line before he returns with Beerus. As Whis moves out of sight he begins to question the character of Fu, believing that he is planning something but decides to leave things up to Goku and Vegeta.

Super Saiyan: Berserk Goku

Meanwhile in the Green Area, Goku: Xeno has gone off alone in search of Fu, leaving behind Goku, Vegeta and Future Mai. When Vegeta voices his vow to capture Fu in order to make him tell them where Trunks is, a flying communications device approaches and with Fu speaking through it, tells them that others will now be coming for them in order to get the Special Dragon Ball in their possession. The Saiyan pair then feel a powerful ki approaching and immediately turn into Super Saiyan Blue as the evil Saiyan named Cunber, bound in restraints lands before them.

Goku rushes in for an attack but Cunber catches the incoming Goku with an attack that is able to corrupt the opponent's ki. This causes Goku to drop out of his Super Saiyan Blue form and into a Super Saiyan: Berserk. Vegeta tosses the Special Dragon Ball to Mai to hold on to as he now finds himself defending against a Goku who has turned on him, his mind having been overtaken. After Goku smashes Vegeta into the ground he soon turns on Mai but he is intercepted by the sudden appearance of Trunks. Cooler also arrives for assistance, knocking Goku backwards with a whip of his tail.

Golden Cooler

Fu voices his surprise at how Trunks was able to escape the Slum Area even though he had put handcuffs on him that seal ki as well as his apparent team up with Cooler. He goads Cooler by saying that he should have brought his brother Frieza to the planet instead due to him having the stronger transformation. Cooler however responds by saying that whatever Frieza can do, he can do also as he transforms into a Golden new form. Cooler leaps into the air and powers up a Golden Super Nova which he launches directly at Goku. The amount of power given out causes Cooler to power back down to his Fourth Transformation but the attack was enough to knock Goku down.

As Trunks goes to check on Goku, he see's that he has now regained his senses. Mai then removes a pair of Potara from her pocket, having been given to her by Shin before heading to the Prison Planet. While they begin the process to fuse together, Trunks rushes in to draw Cunber's attention away but he is beaten without effort while Golden Cooler's repeated volley of ki blasts has no effect. The two Saiyans fuse to become Vegito who transforms into Super Saiyan Blue as he heads directly for Cunber.

Vegito vs. Cunber

Having saved Trunks, Vegito orders him to stay back as he heads into battle with Cunber. The two fighters clash briefly with Cunber commenting on how amazed he is that he has found a worthy opponent and that destroying him will bring him enjoyment. Cunber charges up a Désastre Claw which he directs towards Vegito, sending him crashing back into the cliffside. In response, Vegito uses the Super Saiyan Blue Kaio-ken and engages in combat with Cunber once again. Meanwhile, Future Mai assists Trunks in moving away from the battlefield though he mentions how incredible the two battling warriors energy is.

Golden Great Ape Cunber

As Vegito and Cunber continue to battle it out, Cooler watching from above notices the chain surrounding the Prison Planet beginning to crack. Cunber fired up an even more powerful energy blast than before and Vegito responds by using the Final Kamehameha to counter it. After a struggle on both sides, the blasts cancel each other out though a section of the chain breaks. Cunber launches a Power Ball into the sky which causes him to transform into a Golden Great Ape and fires another blast at Vegito though he immediately splits back into Goku and Vegito having used up all their power. As Cunber continues his rampage, launching blasts in the surrounding area, the barrier covering the Prison Planet begins to crack though it goers unnoticed by Fu who is eager for the fighting to continue.

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 Cunbers tail but even at his great size he proves to be swift enough to defend himself.

Super Saiyan Blue Goku

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 Cunbers 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.

Super Fu

Fu powers up

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 a 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 Coolers 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 recognise it.
