Kamen Rider

Kamen Rider has been around since the early 1970s in Japan. The series under this umbrella have one thing in common: a young man (or in movies, a woman) who wears a special belt and changes into an armored figure. Kamen Rider has been imported twice into English-speaking countries: Saban's Masked Rider and Kamen Rider Dragon Knight. All stories here will be for the Japanese series. Since I write a lot of Kamen Rider stories but the number vary per series, I'm using the same Tiny-Huge size indicator as on the main fandom page.
