Potage has the appearance of an old man, due to being at least 100 years old. He has a large beard covering most of his face, with a bald head and gray sideburns. He wears a sort of yellow protective suit of some sort, with yellow boots and sort of light brown pants as garments, most likely as a defense against invaders. His skin is a light blue color, with a sort of brown color covering on his eyes.
Potage is a very noble character. For most of his life, he has done the honorable thing and protected his planet and the universe from the threat of Commeson. Unlike other fighters, he has a rather happy personality, as he went so far as hugging Monaka, a simple deliveryman, when he saw him. Although he has many noble traits, he is shown to be somewhat egotistical as he gloated about his protection of the universe from Commeson. He is shown to be fearful when he fights an opponent or opponents that are stronger than him, as he is seen quivering when Gryll and his henchmen begin to attack. He is also very informed about the history of his planet and Commeson, due to being its sole protector. Potage is not used to seeing such powerful fighters, as he is in complete shock when Trunks and Goten make quick work of Gyrll's henchmen.
Potage was seen training by himself on Planet Potaufeu when he was confronted by Gryll, an intergalactic criminal, and his henchmen. Later that day, when Monaka arrives to deliver a martial arts magazine that Potage ordered, Potage was once again confronted by Gryll and his henchmen. Potage assumes a battle stance, but as they begin to attack him, Potage falls back, afraid. Goten and Trunks, who were trapped in Monaka's delivery truck without him realizing, easily defeat Gryll's henchmen, and they retreat, but not before spotting the key to the Superhuman Water that Potage usually carries around his neck, laying on ground, with Potage not realizing that he lost the key until it was too late. Gryll and his henchmen appear once again with the key in their possession. Goten and Trunks prepare to take the key back, but they are forced to stand down since Monaka was taken hostage.
At the location where the Superhuman Water was being kept, Potage is tied up with Trunks and Goten, warning Gryll that if he undoes the seal, he will be the one who gets swallowed up. Ignoring him, Gryll uses the key to unlock the door of the compartment the Superhuman Water was being kept in. Gryll then looks inside the container, and screams. Later, Trunks and Goten are fleeing from Gryll and his henchmen, who are now purple in color, with Trunks carrying Potage. Trunks is grazed by an attack and falls to the ground, but when he is targeted again, Vegeta appears, having traveled to Planet Potaufeu with Jaco to recover Goten and Trunks, and deflects the blast. Potage then witnesses as Vegeta easily defeats Gryll's henchmen, and when he is captured by the purple goo and Copy-Vegeta is created.
When Copy-Vegeta demonstrated to the real Vegeta that his powers were taken, as well as his form, Potage is hiding behind Trunks, afraid that a stronger enemy has showed up. After escaping Copy-Vegeta and Copy-Gryll, Potage explains to everyone that their enemies are entities made from the Superhuman Water. While Jaco explains the Superhuman Water, Potage corrects him, saying that the "Superhuman Water" name was
made up and was false, the real name of the weapon being Commeson. Commeson, while created for Potaufeu's protection, created lot of havoc in the past, that the inhabitants of Potaufeu sealed it at the expense of their lives, with Potage being the only survivor, and he has been protecting the seal for over a hundred years.
Later, when Gotenks is fighting a one-sided battle with Copy-Vegeta, Potage is hiding behind the original Vegeta, realizing that Gotenks' attacks are useless. He, along with Jaco, then notice Vegeta's body becoming transparent, a side effect from being a victim of Commeson. He then witnesses Gotenks being defeated by Copy-Vegeta, and Goku then appears to take over the fight. Potage is surprised to see Commeson attempting to control Copy-Vegeta, but even further surprised to see Vegeta's will overpowering Commeson's control, which in turn caused Copy-Vegeta to attack Copy-Gryll.
Potage watches as Goku and Copy-Vegeta fight an evenly matched battle, even as Super Saiyan Blues. Potage is confused when Vegeta tries to explain the transformation. As Vegeta's body is disappearing further, Potage tells him to suck on the key of the seal, which could buy him time. Potage then explains that if the core of Commeson is crushed, the copy would become weaker, and Trunks, Goten and Jaco accompany him in finding Copy-Gryll, which the core was attached to. The core is then discovered and chases the group, who flies back to Vegeta's side. Goku and Copy-Vegeta's blows cause a bright light, as the core tries to attack Trunks and is casually stepped on by Monaka. Goku then destroys Copy-Vegeta, ending things. Potage seals the core back, and thanks Monaka and everyone else for their efforts, telling Trunks and Goten they can visit anytime.
It is stated by Potage that the inhabitants of Planet Potaufeu were weak, which drove them to create Commeson as a weapon for self-defense. Potage was at least interested in martial arts, as he had ordered a martial arts magazine that Monaka delivered for him, and when he assumed a battle stance confronting Gryll and his henchmen, Trunks thought that Potage was strong, as his battle stance was considered strong. However, this was proven false as Potage immediately cowered back as Gryll's henchmen stepped forward.
- Potage's name presumably comes from "Potage", an old French name for thick soups, stews, or porridges. With the name of Potage's planet, Potaufeu, coming from "Pot-au-feu", a French stew.
