Metal Knight, alias Dr. Bofoi, holds the sixth rank among the Hero Association’s S-Class heroes, deploying fleets of remote-controlled combat robots rather than engaging directly. Cloaked in anonymity, he orchestrates battles from afar, prioritizing strategic efficiency and technological supremacy over personal risk or emotional investment. His decisions reflect a detached, calculating intellect, often clashing with conventional heroism. Bofoi’s past remains shrouded, his motives veiled behind a pattern of self-interest. He once launched experimental missiles at a city-threatening meteor, valuing data collection over civilian evacuation. During the Monster Association crisis, he advocated obliterating the hideout—hostages included—drawing condemnation from allies like Child Emperor. Ruthless pragmatism drives his relentless acquisition of advanced tech, from salvaging alien wreckage like Boros’ warship to repurposing enemy weaponry for his shadowy projects. His signature combat unit, the Metal Knight Robot, boasts missiles, flight systems, and near-impenetrable armor. Though it faltered against foes like Elder Centipede and fell to Orochi’s onslaught, the Monster Association exploited its captured remains to replicate his designs. Bofoi engineered the Hero Association’s fortress and defense grids, yet these feats are tinged with unease; colleagues question whether his innovations serve protection or hidden agendas. Tensions simmer with fellow heroes. Drive Knight cautions Genos against Bofoi, hinting at ties to the Mad Cyborg that ravaged Genos’ past. Child Emperor publicly denounces his merciless tactics, despite sporadic collaboration. Bofoi’s rare gestures of concern—like distributing radiation antidotes post-battle—clash with his otherwise icy demeanor. He sidesteps direct conflict, dismissing the Monster Association raid as a trap and arriving post-battle to scavenge debris with drones. This aloofness fuels theories of a burgeoning mechanical army or imminent betrayal. His allegiance wavers between bolstering humanity’s defenses and advancing inscrutable personal goals, leaving allies and enemies alike to grapple with his ambiguous moral compass. Across narratives, Bofoi’s enigma persists. Speculation swirls around potential connections to looming threats, yet his true intentions remain locked behind layers of secrecy, ensuring every act of technological prowess doubles as a riddle.
