Baikinman is the primary foe to the bread superhero Anpanman, and is the most recurring antagonist in the Anpanman books and anime.
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 Dokin-chan. He also has other allies such as a germ army.
