Movie
Description
Hailing from Baikin Planet, Baikinman arrived on Earth as an egg that hatched the very day Anpanman was born, cementing their cosmic rivalry as opposing forces from inception. His anthropomorphic design resembles a fly, featuring a black furry body, wings, purple lips, a zigzag tail, and a slimy blue tongue, drawing direct inspiration from Beelzebub, the demonic "Lord of the Flies" in Christian lore. A severe allergy to cleanliness forms his core weakness; exposure to soap or water causes his body to turn white and shrink drastically.

As the primary antagonist, Baikinman dedicates himself to defeating Anpanman and spreading germs, frequently deploying mechanical inventions and robots in elaborate schemes. Beneath his malicious pursuits lies complexity: narcissistic and impulsive, he occasionally reveals vulnerability, including a latent desire for normalcy noted by creator Takashi Yanase. His resilience shines through persistent returns after repeated defeats, often punctuated by his signature catchphrases "Ha-hi-hu-he-ho!" and "Bye-baikiiin!" during retreats.

Relationships further define him. He harbors unrequited affection for his frequent partner-in-crime, Dokin-chan, enduring her bossiness while aiding her schemes despite her crush on Shokupanman. He created Franken Robo-kun to combat Anpanman, but the robot developed a gentle nature, viewing Baikinman as a father figure and persistently attempting to hug him—a gesture Baikinman reluctantly tolerates despite the robot’s electric shocks. Baikinman also implanted Rollpanna with a "Baikin Plant" during her creation, triggering her dual-hearted nature (red for goodness, blue for evil). Though he initially manipulates her evil side against Anpanman, Rollpanna increasingly defies his control.

A significant development occurs in the 2024 film *Anpanman: Baikinman and Lulun in the Picture Book*, where Baikinman is magically trapped inside a picture book. Within this realm, he encounters the fairy Lulun and attempts to reinvent himself as a hero by battling a giant elephant. This endeavor ultimately fails, leading Lulun to summon Anpanman for resolution, marking a departure from his typical villainy to explore his capacity for aspirational change, albeit short-lived.

His background carries cultural influence; his design inspired germ personifications in other media, such as a computer virus depiction in a banned *Pokémon* episode. Furthermore, the character Vaccine Man from *One-Punch Man* serves as a direct parody and shares Baikinman’s Japanese voice actor.
