Movie
Description
Kevin Mask, son of British justice chojin Robin Mask and Alisa Mackintosh, endured strict childhood training under his father that prompted him to flee home at age eight. Seeking rebellion, he joined the brutal chojin faction d.M.p, undergoing hellish training where he befriended fellow trainee Mars. During his d.M.p tenure, he received a spider nest tattoo on his back that imprints the image of every defeated chojin—a tradition continuing post-departure.

Initially antagonistic, Kevin executed d.M.p operations against justice chojin including attacks on Mantaro Kinniku and Gazelleman. Disillusionment grew from the group's dishonorable tactics and absence of teamwork, notably during Tel Tel Boy's match where cheating occurred. This spurred his abandonment of d.M.p to operate independently, rejecting both evil and justice affiliations while preserving his brutal combat methodology.

He maintains a complex, adversarial dynamic with his father, addressing him as "Daddy" while resenting past strictness. This friction historically impaired his battle focus when Robin was referenced, though shared experiences gradually improved their bond. Their reconciliation culminated in Kevin wearing Robin's fractured mask during the Chojin Crown finals as tribute.

In the Chojin Olympics: The Resurrection arc, Kevin trained under Warsman disguised as "Croè," deepening his capacity to trust while retaining his lone wolf identity. He secured victory in British preliminaries via his signature Big Ben Edge technique, later representing the UK in Olympic events including "Daruma Otoshibam" and "Beach Flags."

His rivalry with Mantaro Kinniku evolved from dismissing friendship overtures to mutual hatred during the Demon Seed arc, where defeating each other superseded external threats. Forced collaboration in the Ultimate Chojin Tag Tournament forged mutual respect, establishing the tag team "The Young Masters" and solidifying reluctant camaraderie.

Physically, Kevin stands 7'2" (218 cm) tall weighing 155 kg, with blond hair (blondish-brown in anime) extending to his mid-back and yellow eyes visible beneath his helmet. He dons blue or black armor—the latter a rebellion against his father's white gear—and anime streetwear with pink accents. He rides a motorcycle and favors leather attire.

His abilities encompass the hereditary Maelstrom Power, analogous to the Kinniku clan's "Burning Inner Strength." His fighting style emphasizes speed, precision, and tactical planning, featuring signature techniques like Robin's inherited Tower Bridge and the piledriver variant Big Ben Bash. Combat retains ruthless efficiency reflecting his brutal origins.

Post-series, Kevin reigns as Chojin Crown champion, having embraced his heroic legacy while preserving his independent identity—balancing inherited justice duties with personal ethos.
