Max bears the designation JHR005 within the Hikarian team, distinguished as its largest and strongest member with a physique emphasizing formidable strength. His signature weapon, a colossal hammer, serves as his primary tool in clashes against adversaries such as the Bratchet gang. Originating as an energy-based life-form from Planet Hikarian, he inhabits a mechanized body modeled after Earth’s bullet trains to maintain a physical presence on the planet. These forms function as conventional locomotives during peacetime, transforming into battle-ready robotic configurations upon the activation command *"Hikarian Change!"* Deployed consistently as a frontline combatant, Max specializes in raw power during confrontations. While later Hikarian units gained access to Combining Mecha systems in subsequent series, existing records lack specifics on his integration into such upgrades or extended plot developments. His engagements with human allies and foes occur strictly within team-based operations focused on neutralizing threats, maintaining a narrative emphasis on collective action over personal backstory or individual character arcs. Documented materials do not address his potential involvement in spin-off media, cinematic features, or OVA adaptations.
