Baikinman, hailing from Baikin Planet, arrived on Earth as an egg that hatched simultaneously with Anpanman’s creation. Modeled as an anthropomorphic germ mirroring a fly, his design blends a black furry torso, pink eyes, purple lips, translucent wings, wiry antennas, a jagged tail, and a slick blue tongue. His aesthetic evokes Beelzebub, the "Lord of the Flies," while embodying black bread mold—a direct counter to Anpanman, whose bread-based head symbolizes their rivalry. As the series’ central antagonist, Baikinman fixates on overthrowing Anpanman, a mission rooted in his origin. His volatile mix of narcissism, rashness, and self-aggrandized brilliance fuels schemes involving intricate mechanical contraptions designed to dismantle his foe. Yet traces of depth emerge: fleeting reluctance to injure Anpanman or covert concern for creations like Franken Robo-kun, a robot he avoids for its unanticipated benevolence. Interpersonal ties complicate his narrative. Unreciprocated affection for Dokin-chan persists despite her allegiance to Shokupanman, though they ally for shared goals. His exploitation of Rollpanna—planting bacteria grass to awaken her darker impulses—reveals strategic cunning, yet her evasion of Anpanman thwarts his plans. In *Shine! Kulun and the Stars of Life* (2018), Baikinman begrudgingly aids in saving Anpanman when tempted by the chance to taste his rival’s head, only to reject the offer out of pride. The 2020 film *Fuwafuwa Fuwari to Kumo no Kuni* depicts his creation of the black cloud Baigumora to seize Cloud Kingdom, destabilizing weather systems until Anpanman restores balance. Each defeat, however, fuels his relentless resurgence. Creator Takashi Yanase highlighted Baikinman’s suppressed yearning for ordinary life, clashing with his ingrained villainy. This internal tension, paired with gluttonous humor and the signature taunt “Hahihuheho,” solidifies his layered persona. His cultural impact extends to germ-themed parodies, including *One-Punch Man*’s Vaccine Man, echoing his enduring legacy.
