Harabote Muscle, formally named Vance McMadd in English adaptations, chairs the Chōjin Committee, governing global Chōjin operations. A lifelong companion and rival to Mayumi Kinniku, their bond evolves from youthful camaraderie to charged competition. Together, they uncovered Nemesis’s imprisonment in their youth, an encounter that inspired Mayumi’s vow to reshape the Kinniku Clan—a pivotal event intertwining their destinies.

A retired Chōjin wrestler, Harabote clinched victory at the 11th Chōjin Olympics, shattering Mayumi’s bid for a third title. His arsenal—Body Scissors, Killer Key Lock, and Atomic Drop—showcases a methodical grappling prowess. Despite his authoritative role, he endures mockery from peers, branded “Little Fatass” and “Beer Belly,” his leadership frequently overshadowed by clashes with Suguru Kinnikuman over the latter’s irreverent conduct during tournaments like the Survivor Match for the Kinniku Throne.

His administrative competence wanes over time, eroding his standing in *Kinnikuman Nisei*. Bitter toward Mantarō Kinniku, Suguru’s son, he dismisses the heir as unambitious, leveraging biased judgments in events such as the HF First Year Replacement Matches to undermine him. This animosity extends to his successor, Ikemen Muscle, who mirrors his father’s contempt for Mantarō.

Harabote and Mayumi sustain a rivalry tempered by grudging respect, their sporadic exhibition matches reviving obsolete techniques to audience exasperation. These clashes inject levity into earlier narratives, counterbalancing his austere public image. Physically stout with a rounded midsection, he dons a regal cape and a cranial fin echoing his Planet Kinniku heritage.

His tenure as chairman anchors pivotal crises: the Seven Devil Chōjin conflicts and the Golden Mask upheaval, during which he and fellow justice warriors faced temporary defeat. Though flawed, his stewardship bridges eras from Suguru’s ascendancy to Mantarō’s trials, etching his influence into Chōjin history’s core.
