Muscle Tower's fifth floor, only accessible via a trapdoor on the sixth. Initially, Buyon appears to be a seemingly indestructible threat to Goku and Android 8, as every technique Goku uses against him, from a Kamehameha to the stomach or a kick to the face, is bounced back effortlessly by Buyon's lard. The monster can also cast electrical blasts from his antennae. Buyon apparently feeds on cattle supplied by his keepers, and even comes close to devouring Goku and Android 8 during the encounter.
Through a long and tiring process, Goku eventually realizes that Buyon is susceptible to the cold, and after Goku knocks a small hole into the wall, Buyon is frozen solid. With this, Goku strikes the clone with a hard enough punch to shatter him into pieces.
