Beansman hails from Planet Rakka, a world under invasion by the Space Samurai forces led by Black King. He journeys to Earth specifically to plead for aid from Kinnikuman and the Justice Choujin, acting as the catalyst that draws them into the conflict on his homeworld. His narrative function directly parallels the villagers seeking protection in *The Seven Samurai*, uniting the champions against a shared enemy.

Physically, Beansman is distinguished by purple hair and matching purple eyes. He consistently wears a headband as a visual identifier. His background is defined by his connection to Planet Rakka, though details regarding his species, family, or life before the invasion are undefined.

Functionally, Beansman serves as the supplicant who bridges the Justice Choujin and the crisis on Planet Rakka. His appeal initiates the primary storyline of the TV special, directly leading to the formation of the team assembled to confront Black King and the Space Samurai. His purpose centers on facilitating this confrontation, not independent character development or the display of personal combat abilities.

His documented involvement is confined solely to the events of the Planet Rakka arc TV special.
