* BreakoutRole: The is Seiji Takaiwa's aka [[FanNickname Mr. Kamen Rider's]] first stint as a Suit Actor for Kamen Rider. Since then, he's played EVERY single primary Rider except for Hibiki, with over 14 Heisei Riders under his belt ([[IncrediblyLamePun or rather their belts]]).
* MilestoneCelebration - This series was made during Kamen Rider's 30th anniversary and contain homages to past Kamen Rider Series. Some of the monsters are based on old villain's, and you can make the case the lead riders themselves are based on previous Kamen Riders. It also homages the ''Franchise/MetalHeroes'' series which Kamen Rider took the place of and incorporated some concepts.
* OlderThanTheyThink: While [[KamenRiderStronger Tackle's]] status as a Kamen Rider continues to be debated upon, [[KamenRiderRyuki Femme]] is not the first female to be shown transforming into an undeniable Kamen Rider form, and [[KamenRiderHibiki Shuki]] isn't the first female Rider either on TV. Both of those honors go to [[spoiler: Yukina Sawaki, Shouichi's older sister and the first Agito, who is even shown in a flashback to (unwillingly and painfully) transform into Agito Ground Form.]] While she did not become an active Rider like [[spoiler: her brother]] or her more well known successors did, this is still an undeniable case of the first female Kamen Rider, at least within the Heisei Era
