Shin, who has also visited the planet along with Old Kai calls for a lunch break. Future Mai (another visitor) urgently heads to the others to tell them that Future Trunks has been kidnapped and Goku confirms that he is unable to sense Trunks' energy.


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.

Goku vs. Goku: Xeno

Seeing the look on Fu's face, Vegeta realizes that he's up to something and Fu tells him that where they are is an experimental place that he created and he is taking powerful fighters from different planets and different era's and having them fight there confirming that he was one who also took Trunks. Mai demands that he explain what his purpose for doing this is only for Fu to casually explain that it's just out of fun and curiosity. Vegeta becomes angry and soon fires a blast at Fu though he sends it away by opening another space distortion that it passes through. Fu gives Vegeta a Dragon Ball and explains that other strong people have the other six and they must collect them all if they wish to escape and that this will be a free for all as he teleports himself away to a place where he continue watching the battles from afar.

Meanwhile Trunks wakes up in a cell. In the manga Cooler breaks into the cell and demands a Dragon Ball. In the anime the doors open allowing him to leave, however as soon as he heads outside he is confronted by Cooler who demands one of the Dragon Balls from him though Trunks has no idea what he means.

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.

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.

Cooler then proceeds to engage Cunber but is swiftly defeated, before Cunber can kill Cooler, he is saved by Future Trunks. Super Saiyan God Goku and Super Saiyan Blue Vegeta then arrive and knock Cunber back with a combined kick, seeing Goku's Super Saiyan God form Cunber is enraged and breaks his restraints. Mai blinds Cunber with a flashbang but as soon as he can see again he charges Super Saiyan God Goku - only to find it was Oolong in disguise, Cunber is then immediatly attacked by the now fused Saiyans - who used the Potara Shin had given Mai to become Vegito Blue once again. As Vegito and Cunber battle, Majin Ozotto appears before deciding to leave, noting that Vegito and Cunber are too troublesome. Cooler grabs Trunks and follows Ozotto through the portal he opened, aiming to find out more about the Special Dragon Balls.

Vegeta then battles Super Saiyan: Berserk Goku until Future Trunks arrives, Vegeta has Future Trunks - now a Super Saiyan - engage Goku while he heads to fight the Evil Saiyan. Vegeta is stopped by Cooler, who proceeds to battle Goku - when it appears he is losing he becomes Golden Cooler and knocks him down with one punch, before firing a Golden Supernova at Cunber, though it has no effect.

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.

In the manga, the battle between Super Saiyan Blue Vegito and Super Saiyan Cunber heats up as Vegito decides to get serious by revealing the Kaio-ken. Cunber retorts by saying he too will get serious and uses a Power Ball to transform into a Golden Great Ape.

The Ghost Warriors

Now in the Chaos Area of Prison Planet, Trunks asks Cooler why he decided to go after Ozotto and he responds by telling him that Ozotto seemed to know where the Dragon Balls are. There they soon see King Cold badly injured up against a rock while the rest of his forces lay dead around him. Just then the Ghost Warriors of Cell, Kid Buu, Bojack, Turles and Lord Slug appear. They battle Future Trunks and Cooler but any attacks against the Ghost Warriors prove futile as they turn into smoke and reform back to normal immediately. Cooler transforms into Golden Cooler and it is at this point that King Cold is revealed to still be alive, complimenting his son on how strong he has become since the last time he saw him. King Cold shows him the Four-Star Special Dragon Ball and asks if Cooler will fight along side him and for him. However Cooler fires a Death Beam]] through him, killing him, not wanting to be taken advantage of and recovers the Dragon Ball from him.

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 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.
