The future Kinnikuman Mariposa was born on the same day and in the same hospital as Kinnikuman and four other young boys, but because of a fire the children were mixed up and the true heir of their home planet may have been misplaced. His family moved to Planet Moctezuma (モクテスマ星, Mokutesuma-sei?), a planet with an atmosphere so thin its inhabitants were forced to wear oxygen masks. Because of this, he grew up with a tough heart and amazing jumping abilities, and because he also grew up poor, he soon turned to a life of theft. While living as a thief, he stole the Robin Family heirloom the Anoalo Sceptre (アノアロの杖, Anoaro no Tsue?). After Kinnikuman had proven himself worthy to become the next king of his home planet, five evil gods sought out the other potential heirs and gave them great choujin power to become the Five Fated Princes, who all claimed to be the true heir. Mariposa was chosen by the God of Flight (飛翔の神, Hishou no Kami?). A royal survivor series was organized to determine who was worthy of ascending the throne.
Kinnikuman Mariposa's team fought the true Kinnikuman and his allies in the first round in Kumamoto Castle. Mariposa ended up fighting Robin Mask himself, making use of the stolen sceptre. He was stunned by a beam from a temple on Planet Kinniku when he tried to use a fake Muscle Revenger, a sacred technique used by the Kinniku Royal family, and was ultimately beaten by Robin's Robin Special, giving him his revenge.
