"I was born to defeat you, Anpanman!" -Baikinman

Baikinman (バイキンマン) is the main antagonist of the Anpanman books and anime series. He came to earth from Baikin Planet in an egg as a baby to enslave the planet. Anpanman, who was born the same day, always stops him and his shenanigans, saving the day.


Baikinman is an anthropomorphic Demonic germ who resembles a fly with large teeth, pink eyes, purple lips, two antennas, fly-like wings, a purple nose, a zigzag-shaped tail, a black furry body, and a slimy blue tongue. Baikinman, himself as a germ entity, wants to spread germs and bacteria to Anpanman and his friends. He is weak to soap, which shrinks him. He establishes his crimes through riding a personal UFO that sometimes extends its grip to capture innocent people. He also keeps a collection of vehicles/tools that harms his enemies. Baikinman usually gets defeated by Anpanman or an ally in the anime.


Baikinman's primary ally is Dokinchan. He also has other allies such as a germ army.


  • Baikinman's design was heavily based on Beelzebub of the Christian religion. The Dictionnaire Infernal describes Beelzebub as a demonic fly who is also known as the "Lord of the Flies", which was an inspiration for Baikinman's fly-like appearance. He's also a personification of the black bread mold (Rhizopus stolonifer), which was found on bread surfaces and causes a damage to bread, which would make Baikinman an enemy to Anpanman, whose head is a bread.
  • Baikinman's popularity inspired artists to produce personifications of germs and diseases in Japan. One example is in the banned Pokémon episode "Electric Soldier Porygon", which has a computer virus in Ash Ketchum's explanation of viruses resembling Baikinman.
  • In the web anime series One Punch Man, the villain Vaccine Man was based on Baikinman. He is even voiced by Ryusei Nakao, who voiced Baikinman in the Anpanman anime.
