WARNING: The following contains spoilers for Dragon Ball Super Chapter 71, by Akira Toriyama, Toyotarou, Caleb Cook and Brandon Bovia, available now in English from Viz Media.
Previously in Dragon Ball Super, Granolah -- who is the last surviving Cerealian -- used the power of his planet's Dragon Balls to become the most powerful fighter in the universe at the cost of his remaining life. With the goal in mind of killing Freeza, who is responsible for the destruction of the Cerealians, Granolah set out to get information from the Heeters about the villain's whereabouts. After thoroughly beating up the Heeters, their leader, Elec, told Granolah they would find out where Freeza was, though he soon made plans to double-cross the last Cerealian and send him against Goku and Vegeta. Now, Dragon Ball Super Chapter 71 reveals just how Elec set about orchestrating a confrontation between Granolah and the Z-Fighters.
At the start of Dragon Ball Super Chapter 71, Granolah returns to Planet Cereal, where he watches over Monaito, the planet's last Namekian and the one powering the Dragon Balls. Meanwhile, Elec dispatches Oil and Macki to get information from Zuno, the powerful being with knowledge of pretty much the entire multiverse. After Zuno acts particularly lecherous towards Macki, the duo successfully get information to help them in their quest.
From there, Macki and Oil head to Earth, where they tell Chi-Chi (who is, as is becoming usual, worried about money) that they'll pay her a massive amount for help from Goku in taking care of a villain named Granolah. Chi-Chi and, seemingly, Bulma buy into Macki and Oil's scam. The two women summon their husbands back from Beerus' planet, where they've been training to reach the level of deities. However, at some point, Macki and Oil steal the Dragon Radar with plans of using it to get Planet Cereal's Dragon Balls, which don't turn to stone after use like those on Earth.
After selling Goku and Vegeta on their story that Granolah is a majorly evil villain of incredible strength, the intrigued Goku and Vegeta set out to take on their mysterious new foe. However, when they arrive on Planet Cereal, Macki and Oil take advantage of Granolah's hate for the Saiyans -- who made up the army that Freeza used to wipe out the Cerealians -- and claim that Goku and Vegeta are actually assassins. As such, Granolah and the Z-Fighters both believe that the other part is actually villainous, thus setting the stage for a major confrontation.
The fight between Goku, Vegeta and Granolah is sure to be a major one, but the group is likely to figure out what's going on sooner rather than later. However, it's much more troubling that the Heeters are looking for the Dragon Balls. If successful, they could easily take advantage of Planet Cereal's Dragon Balls not turning to stone to get an absurd number of wishes. Despite there only being two Dragon Balls to collect, there's no indication that Planet Cereal's version of the famously powerful artifacts have any major limits. They were, after all, able to turn Granolah into one of the universe's strongest fighters.
As such, getting the Dragon Balls and using them for their own nefarious purposes is the Heeters' true goal. With them, Elec and his goons will be able to finally carry out their goal of defeating Freeza and taking over the universe. That being said, Dragon Balls are generally tied to a planet's Namekian. This means that Monaito, who is old and fragile, is key to the Heeters' accomplishing their goals, so that's a problem they'll have to contend with sooner rather than later.
Dragon Ball Super Chapter 72 releases May 20.
