'''''Kamen Rider OOO Wonderful: The Shogun and the 21 Core Medals''''' is the summer movie of ''Series/KamenRiderOOO'', shown alongside ''Film/KaizokuSentaiGokaigerTheMovieTheFlyingGhostShip''.
!!''Kamen Rider OOO Wonderful: The Shogun and the 21 Core Medals'' provides examples of the following tropes:

* EarlyBirdCameo: Not only does OOO's successor, Series/KamenRiderFourze, make his first appearance in this movie, but so does one of the supporting cast members of his series. In this case, Yuki Jojima.
* EnemyMine: [[spoiler:the Greeed offer their Core Medals in order to help OOO fight Gara's OneWingedAngel.]]
* FastballSpecial: Eiji gets fascinated when Fourze demonstrates his powers, until Fourze decides to use the Magic Hand Switch to throw OOO at Gara.
* GenreSavvy: the [=GataKiriBa=] clones ''are'' taking too long to transform into the various combos (did they really have to do it one at a time?), so Gara tried attacking them, but the Core Medals used in the TransformationSequence formed a barrier of sorts.
* ItWasAGift: OOO receives the medals for his [=BuraKaWani=] combo from Tokugawa Yoshimune.
