Meat begins as a sidekick aiding Kinnikuman (Suguru Kinniku) in his early endeavors as a superhero prince, facing evil Chōjin and competing in wrestling tournaments. This role extends to the next generation, where Meat serves as the loyal partner to Mantaro Kinniku (Kid Muscle), Kinnikuman's son, supporting him in defending Earth against threats such as the villainous DMP (Dangerous Mind Power) group.

Partnered with Mantaro, Meat actively assists in the mission to secure the powerful mystical artifact, the Muscle Ninjin, targeted by destructive factions like the DMP. He fights alongside Mantaro against these adversaries, contributing to Mantaro's growth, his mastery of inherited abilities, and his quest to uphold his father's heroic legacy. Meat's presence reinforces the central themes of friendship and perseverance in Mantaro's development as a Chōjin wrestler.

The character consistently fulfills his supportive function throughout the narrative, aiding Mantaro and his allies against recurring antagonists like Scarface and other DMP members during high-stakes wrestling confrontations. This continuity spans multiple story arcs focused on retrieving the Muscle Ninjin and broader conflicts against universal threats.
