Grill is shown to be a teal humanoid sapient. His head has the shape of the head of a pickaxe, with his head pointed. He has a rather muscular body, with orange markings on his shoulders. His abdomen is an orange color, almost like a steel abdomen. His only article of clothing is some sort of spandex on his waist.
HIs personality is that of a common criminal. He only cares about obtaining the Superhuman Water to enhance his own abilities, and does not seem to care about his henchmen, while they seem to care more about him then he cares about them. He is willing to resort to taking hostages and killing them to get what he wants, as he took Monaka hostage to get the key for the "Superhuman Water". Gryll does not take Potages words into meaning when he tells him the Superhuman Water does not exist.
Gryll and his henchmen headed to Planet Potaufeu in order to obtain the Superhuman Water. They found Potage training in the middle of the night, yet Potage was able to evade them for the night.
When Trunks, Goten, and Monaka arrived, Gryll and his henchmen had been able to find Potage and the key. Grill then commanded his henchmen to kill Potage, yet he saw as his henchmen were defeated rather easily by Trunks and Goten. After his henchmen battled Potage, Goten and Trunks, Gryll commanded his henchmen to retreat, but not before they managed to capture the group by taking Monaka hostage. Knowing they couldn't allow harm to Monaka, Goten and Trunks surrender and allow themselves to be tied up.
Gryll takes key holding the seal of the Superhuman Water from the captured Potage, and when he opens the canister, he is shocked to see Commeson, a purple liquid that soon absorbed Gryll's powers using the crystal and is swallowed up by it. When Gryll was swallowed up by it, an exact copy of Gryll was created made from Commeson's purple goo. Cloned Gryll then captured Gryll's henchmen, creating copies of them as well. The group then assaulted Goten and Trunks, who were flying away with Potage and Monaka, while Gryll and his henchman are shown to still be weakened and lying on the ground. A few minutes later, Gryll is shown disappearing into the air, with his henchmen soon to follow.
Gryll is not exceptionally powerful as after witnessing Goten and Trunks defeat several of his henchmen he chooses to retreat. When cloned Gryll is created, all of his energy is depleted, and soon disappears into the air. Gryll, along with his henchmen, use ray guns in combat.
