|Kamen Rider ZO|
Kou Domon (土門 廣 Domon Kō?), or Tsutomu Sano (佐野 茂 Sano Tsutomu?) played Masaru Aso, the titular rider of the stand-alone movie, Kamen Rider ZO (1993). He reprised his role only in voice the year after in the short 3-D film, Kamen Rider World, which served as a crossover with Kamen Rider J.
Despite ZO going on to make later minor appearances, including in recent crossover movies, Kou Domon has yet to reprise his role again.
