WARNING: The following contains spoilers for Dragon Ball Super Chapter 57, by Akira Toriyama, Toyotarou, Caleb Cook and Brandon Bovia, available now in English from Viz Media.
The Z-Fighters latest battle for the fate of Earth has begun, with Moro and his freed Galactic Prisoners having invaded the planet earlier in the arc. In Chapter 56, Androids 17 and 18 returned to do battle, as their lack of chi renders them immune to the Moro's energy absorption ability. However, the villain has now arrived on Earth and empowered Saganbo, his chief minion.
Dragon Ball Super Chapter 57 jumps between several big battles on Earth, landing last on the fight between Seven-Three and the Androids. Seven-Three -- who is able to duplicate Moro's absorption technique -- and his partner Shimorekka get absolutely wrecked by the two Androids. Seeing his minions losing, Moro finally steps foot on Earth, saving Seven-Three from complete destruction in the process. Shimorekka takes Seven-Three away to recover, while Gohan and Piccolo size up Moro. The two heroes are absolutely shocked by his chi, which he's bolstered by destroying planets and absorbing their energy.
Instead of opting to fight the Z-Fighters and Androids himself, Moro instead allows Saganbo to fight against the heroes, telling his minion not to kill them in the process. This is when Moro empowers Saganbo with more energy. The new infusion causes Saganbo to grow in size and burst out of his clothes. The villain then launches his attack. However, even the combined force of the Androids, Jaco, Piccolo and Gohan isn't enough to stop him. Saganbo swings Android 17 and Gohan into their companions and then smashes the heroes into the ground.
It's never been entirely clear just how formidable Saganbo really is. Although all of the Galactic Patrol Prisoners are certainly powerful, Saganbo has typically relied on infusions of energy from Moro and the advantages those give him. When Saganbo went head-to-head with Goku on New Namek, the villain managed to best Goku. But Saganbo was only able to win because Moro's energy absorption ability resulted in the hero being unable to use his full abilities.
At the end of Chapter 56, Goku finally arrives on Earth to fight Moro -- meaning a rematch with Saganbo is nigh. Although Goku failed to beat the villain the first time around, if he truly mastered Ultra Instinct while training with Merus, Saganbo doesn't stand a chance this time as that ability doesn't seem to use chi in the same way. Goku just has to get to his fellow Z-Fighters in time.
