Biography
Panput is the egotistical champion of two worldwide Martial arts tournaments other than the World Martial Arts Tournament. He plans on making the 22nd World Martial Arts Tournament his third championship victory, before being defeated by Goku in the 4th match of the 1st round. Tien Shinhan dismisses him as "too cocky."

Panput breaks a wall
His fight against Goku starts with Panput making a flashy entry. However, when he first punches at Goku, he asks if the punch was too fast for him to follow. Goku says "it wasn't much of a punch," so Panput demonstrates his great speed and power by destroying an arena wall with an elbow strike. But, when he attacks Goku again, Goku pulls off a quick three-hit combo to the chest, completely knocking Panput out. The World Tournament Announcer is astonished over the "single-punch" KO, and Goku wins the match.

During the King Piccolo Saga, Panput is killed by Tambourine with a single kick to the face during a kickboxing match. Panput was fighting another opponent when Tambourine showed up and told Panput that he was there to kill him, before delivering his deadly kick. Panput was later revived by the Dragon Balls, along with the other victims of King Piccolo and his children.
