The Prison Planet Saga (監獄惑星編 Kangoku Wakusei Hen) is the third original saga in Dragon Ball Heroes, as well as the first saga of Super Dragon Ball Heroes: Universe Mission.

It is set after the Universe Survival Saga of Dragon Ball Super and the Dark Empire Saga of Super Dragon Ball Heroes.



Future Trunks and Future Mai have returned to the present timeline in their time machine so that Future Trunks can train with Goku and Vegeta.

First Special Dragon Ball

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. 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 see 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.

The match appears to be evenly fought with Fu secretly urging them to keep fighting as it benefits him. Vegeta soon realizes that Goku's opponent is indeed another Goku. They pause briefly but continue once again as Goku finds the prospect of finding another version of himself to be exciting. Goku: Xeno meanwhile is unsure of the power than the other Goku appears to be using.


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 is shown in a cell wondering how to break out when Cooler breaks through a nearby wall and demands he be given the Dragon Ball.

Super Saiyan: Berserk Goku

Meanwhile in the Green Area, Goku: Xeno has gone off alone in search of Fu, leaving behind Goku, Vegeta and 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 Kanba, bound in restraints lands before them.

Goku rushes in for an attack but Kanba 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.

GolCooler Heroes 0 (4)

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 Supernova 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 out.

The nearby Kanba now begins to power up even further, ready to fight for himself.
