Saganbo's History
After escaping from his cell, Moro goes to Saganbo and strikes a deal with him, promising to give them energy and freedom if Saganbo works for him and forms a small army of Galactic Patrol Prisoners to work for him as well. Saganbo agrees, and waits for Moro to free them.
Later, after Moro uses the Namekian Dragon Balls to free the prisoners, Saganbo is seen smiling, pleased that he is free and somewhat surprised that Moro managed to free them. He then uses telekinesis to grab a Ray Gun from one of the Galactic Patrol guards, and then breaks through the window of a control tower. He holds the control tower guard at gun-point, forcing him to give them their ships. Saganbo then tells the other prisoners to join him for fun and for the power they would gain from Moro.
Saganbo steals a very large ship, and he, alongside the rest of the Galactic Patrol prisoners, arrive on New Namek. Moro lands on the ship, where Saganbo comes up to greet him and bow in obedience. Moro compliments Saganbo for bringing an army, and fulfills his part of the bargain, giving Saganbo and the rest of the prisoners some of his energy.
While the prisoners all attack Goku and Vegeta, who are fighting in their Super Saiyan Blue forms, Saganbo watches from on the top of the ship, yelling at the prisoners to keep fighting or else go back to the prison. He also orders them to attack all at once, claiming Goku and Vegeta can't hold all of them off at the same time. Moro then begins collecting energy from the planet once again. Goku, who reverted to his Super Saiyan God form, attempts to stop Moro, but Saganbo jumps down to stop Goku. As they are rushing towards one another, Goku goes down to a Super Saiyan 3, and Saganbo manages to land a blow strong enough to actually knock Goku to the ground, with him reverting to base.
Going back on the ship, Saganbo notices a Galactic Patrol ship in the sky and prepares to shoot it down, but Merus knocks his gun out of his hands using his own blaster. Saganbo is shocked that Merus was able to shoot his gun away at such long distances. After Goku uses Instant Transmission to retreat, Saganbo wonders where Goku and his friends went. Moments later, when the other prisoners are attempting to shoot down the Galactic Patrol ship, Saganbo berates the prisoners for not being able to bring down the ship.
When Moro asks if Saganbo knows of any planets with remarkable life force he tells Moro that before being locked away in prison he used to be part of a crew that rampaged around the galaxy so has a few ideas. He has his scouts scour across the galaxy in search of such planets for Moro and then joins his men on the planet Zoon when stealing the royal treasure.
Later he receives a distress signal from the Macareni Gang on Earth and asks Moro what should be done about it only to be told to send a stronger scouting party there, so Saganbo sends Shimorekka along with Yunba and Seven-Three.
Saganbo is eventually contacted by Shimorekka, and is informed by him that due to the power of Earth's warriors Seven-Three had to unleash Moro's power. Saganbo has Shimorekka switch to monitor so he and Moro can see exactly what is going on. Saganbo tells his men to pull back and suggests to Moro that they destroy Earth as soon as possible, however Moro tells him that they will wait for Goku and Vegeta to return so that they can obtain their energy too.
Eventually, Saganbo and Moro arrive on Earth to confront its defenders. Before Moro can enter battle himself, Saganbo offers to fight in his stead, upon which Moro agrees but orders him to spare them for Moro himself to deal with afterwards. Saganbo agrees, and Moro grants him even more energy to fight, causing Saganbo to bulk up. He charges forward to overpower Android 17 and begins thrashing everyone present, including Gohan, Jaco, Android 18, and Piccolo.
Eventually, Goku arrives to face Moro, but the wizard demands he face Saganbo first, who eagerly agrees to fight in his superior's stead - though quickly finds himself unable to damage Super Saiyan Blue Goku in the slightest and is overwhelmed. After receiving continuous power boosts from Moro, Saganbo becomes more unhinged, sporting a mad grin on his face and becoming more erratic in his attempts to damage Goku, with even the Saiyan demanding Moro stop overstressing Saganbo's weakening body with energy, to which Moro retorts that Goku should keep fighting Saganbo so Moro will not boost his power anymore. To that end, Goku tries to convince Saganbo to stop pushing his body further, but Saganbo is unwilling to listen, hellbent on not going back to the slammer even after hearing about his fellow prisoners' defeats - and collapses dead from the immense bodily stress, no longer able to handle the power boosts Moro had granted him. Moro snarks his disappointment in Saganbo's inability to handle such a "tiny" increase in energy, while an angered Goku prepares to finally face Moro alone. His body gets disintegrated afterwards, from the skirmish between Moro and Goku.
Saganbo's final fate is unknown, as while everyone killed by Moro was wished back to life, Saganbo was still thought dead by the members of the Galactic Bandit Brigade.
