Perman (パーマン Pāman), by Fujiko F Fujio, is a Japanese manga and anime about a clumsy boy, Mitsuo Suwa, who is chosen to apprentice to a powerful superhero. Although created as a parody of Superman (the name "Perman" is based on "Superman" without the "Su"), the character's creators appear to have distanced themselves from this origin story. In the comic-essay "Passionate Days of Perman" (PARマンの情熱的な日々), Fujiko Fujio claims the name is actually a reference to the "par" concept in golf. In addition, due to copyright concerns, the name of Mitsuo's boss was later changed from "Superman" to "Birdman". It is also a comic series in Ninja Hattori; Kenichi really enjoys reading them.
