----
!!''Kamen Rider OOO Wonderful: The Shogun and the 21 Core Medals'' provides examples of the following tropes:

* AlchemyIsMagic: Gara can do a ''lot'' of crazy things with alchemy and Medals.
* BigBad: Gara, one of the four Alchemists that created the Greeed for the First OOO.
* DemonicPossession: Gara long ago lost his body after the King betrayed him and turned him into Cell medals along with his fellow alchemists, so he has to possess a human after being awoken in modern day.
* DugTooDeep: The Kougami Foundation's archaeological dig unearths Gara's tomb in search of secrets he may have buried with him, accidentally unleashing the mad alchemist on the modern world.
* 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.
* EndOfTheWorldAsWeKnowIt: Causing this is Gara's ultimate goal so he can rebuild from the ashes InTheirOwnImage.
* EnemyMine: [[spoiler:the Greeed offer their Core Medals in order to help OOO fight Gara's OneWingedAngel.]]
* EvilCannotComprehendGood: Gara has no comprehension of ''positive'' desire, and is perplexed by Kougami's assertion desire is a creative force, not a destructive one. [[spoiler:This ultimately ruins Gara's plan, as Eiji's overflowing selfless desire to save the people around him overloads his machine when Gara was expecting him to be a self centered monster like the original OOO and himself.]]
* EvilVersusOblivion: [[spoiler:The reason the Greeed oppose Gara and help OOO defeat him. That and he stole their Core Medals.]]
* FastballSpecial: Eiji gets fascinated when Fourze demonstrates his powers, until Fourze decides to use the Magic Hand Switch to throw OOO at Gara.
* GodzillaThreshold:
** [[spoiler:With no other options, Ankh lets Eiji use the Core Medal containing his consciousness to become OOO.]]
** [[spoiler:The Greeed give Eiji their Cores to finish Gara off because [[EvilVersusOblivion they'll be destroyed too if he wins]] and stole their Core Medals to do it.]]
* InTheirOwnImage: Gara's plan is to destroy the world and remake it as he sees fit.
* ItWasAGift: OOO receives the medals for his [=BuraKaWani=] combo from Tokugawa Yoshimune.
* MookMaker: Gara is capable of making entire armies by himself.
* OmnicidalManiac: Gara wants to destroy the world so he can remake it InTheirOwnImage. Mezool compares him and Maki, but Maki quickly shoots down the assumption, as while he also wants to destroy the world, Gara wants to make a new one InTheirOwnImage afterwards while Maki wants the end to be the end.
* OneWingedAngel: Gara transforms into a a monster form after his initial plans are ruined. [[spoiler:He transforms ''again'' after being defeated by OOO and Fourze, turning into a gigantic chimeric dragon-like monstrosity.]]
* RasputinianDeath: [[spoiler:Gara takes the {{Finishing Move}}s of ''all'' of OOO's forms and being shot through the chest by Birth's WaveMotionGun to finally put down once and for all.]]
* SealedEvilInACan: Gara was sealed in Germany until Kougami accidentally unearthed his tomb and set him free.
* YouHaveOutlivedYourUsefulness: Gara and his fellow Alchemists were subjected to this by the First OOO after completing the Greeed, turning them to Cell Medals. In Gara's case, he eventually revived.
