* ActingForTwo: Hiro Mizushima plays both Tendou and his evil twin.
* ActorAllusion - [[Series/KamenRiderRyuki Shiro Kanzaki's]] actor, Kikuchi Kenzaburo, has a cameo as a Zectrooper ''and'' the Worm mimicking him - before promptly impaling him the same way Kamen Rider Odin was once.
** And Kikuchi Mika (no relation) appears in an outfit similar to one she wore on ''Series/TokusouSentaiDekaranger''.
* {{Promoted Fanboy}}s - Tokuyama Hidenori and Uchiyama Masato, who played Yaguruma and Kageyama respectively, are unabashed ''Franchise/KamenRider'' fans, and gladly returned to reprise their roles when the Hoppers appeared briefly and early in ''Series/KamenRiderDecade''.
* StarMakingRole: This was Hiro Mizushima's first starring role, and what catapulted his status into one of the most popular Japanese actors today, as prior to him starring in ''Kabuto'', he only had small appearances in other dramas.
