is a Japanese pro-wrestling-themed tokusatsu/anime superhero television series produced by Tsuburaya Productions, and created by Go Nagai and Ken Ishikawa. Nagai and Ishikawa created three manga series, simply named , published in different magazines by Shogakukan. None of them are related between them or the TV show. They were compiled in a single tankà Âbon in 1978 (Futabasha), 1986 (Asahi Sonorama) and 2001 (Futabasha).
This primarily live-action series is unique, in that, during each climactic battle with the weekly demonic menace, the titular wrestling superhero is able to transform his entire live-action surroundings into anime footage, enabling him to perform superhuman wrestling techniques that are otherwise impossible to perform in live-action.
