I just thought of a double-henshin act sorta similar to Green’s: Kamen Rider W

That was a good show, actually. I wonder if the writer, Riku Sanjo used a similar gimmick in his later stints on some Sentai shows?

Kamen Rider and Super Sentai are kind of related these days: Since 2000, Kamen Rider and Super Sentai shows are aired back-to-back as part of Super Hero Time, they’re both produced by Toei, likely share a lot of production crew, etc…
