- Acting for Two: Hiro Mizushima plays both Tendou and his evil twin.
- Actor Allusion: Shiro Kanzaki's actor, Kenzaburo Kikuchi, has a cameo as a Zectrooper and the Worm mimicking him, before promptly impaling him the same way Kamen Rider Odin was once.
- Promoted Fanboys: Tokuyama Hidenori and Uchiyama Masato, who played Yaguruma and Kageyama respectively, are unabashed Kamen Rider fans, and gladly returned to reprise their roles when the Hoppers appeared briefly and early in Kamen Rider Decade as well as their appearance in Kamen Rider Zi-O.
- Star-Making Role: 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.
- Real Life Writes the Plot: Hiyori's reduced appearance and introduction of Renge was due to Hiyori's actress' failing health.
- Similiar to Super-1, Hiro Mizushima got blacklisted for quitting his agency while Sasword's actor was dropped and retired.
