Mikokatsun is a bio-warrior created by the scientist Dr. Kochin to serve the brain of Dr. Wheelo in the film Dragon Ball Z: The World's Strongest. He is one of three such henchmen, alongside Kishime and Ebifurya. Mikokatsun appears as an enormous yellow ball of putty with a mechanical interior, giving him a rubbery, flexible body. Despite his bulky appearance, he is surprisingly fast and possesses large claws for combat. His primary ability is his extreme flexibility, which allows him to absorb the force of physical strikes and deflect energy attacks such as the Kamehameha back at the opponent, a trait similar to the earlier enemy Buyon. Mikokatsun has no known personal motivations beyond serving his creators. He first engages Master Roshi, successfully deflecting Roshi's Kamehameha, and later ambushes Goku outside Dr. Wheelo's fortress. During the fight, Goku's punches sink into Mikokatsun's body without effect, but Goku ultimately defeats him by using the Kaio-ken technique, which stretches Mikokatsun beyond his limits and causes him to burst. Mikokatsun has no significant relationships with other characters beyond his role as a disposable enforcer, and he undergoes no development over the course of the film. He later makes a brief cameo appearance in Dragon Ball Z: Fusion Reborn among the escaped residents of Hell.
