Kamen Rider Shin starred in his own firect to video movie Shin: Kamen Rider Prologue (1992). He is the second Kamen Rider to mutate into his other form instead of transform (the first was Amazon), as well as the first whose transformation affect his outfit.

She first appeared in Kamen Rider Ryuki: Episode Final. I know technically the photo above is Siren in KRDK, but oh well. Well, I have already said all I could say about her, that she is the first female Kamen Rider and that in America, she appeared in more than one episode of Kamen Rider Dragon Knight as Kamen Rider Siren. Femme was also briefly conjured by Diend in Kamen Rider Decade.

Kamen Rider Ryuuga
Same thing with the last one, above is Onyx is from KRDK. He also appeared in Kamen Rider Ryuki: Episode Final, I have expressed how much I don't like his design since it is just a repaint of Ryuki.
