History Film / KamenRiderZeroOneOthersVulcanValkyrie

* Foreshadowing: Gai stumbles out of the remains of Zaia Japan, recovers his Thousand Driver and swears he'll be a President again, even if it's a totally different company and walks out of the story. This would later be picked up in ''~Genms~ The Presidents'' .

* HistoryRepeatsItself: The film's CentralTheme. KR Metsubojinrai's RoaringRampageofRevenge is interpreted by the remaining Solds as a call-to-arms, causing them to [[spoiler: rebel against Humanity and target A.I.M.S]]; [[CycleOfRevenge re-igniting the tensions the series started out on]]. [[spoiler: Fuwa and Yaiba do eventually manage to get through to them]], though.

* KillEmAll: [[spoiler:By the end, Aruto, Is, Yua, and Amatsu are the only characters in the series still alive.]]

* ResetButtonEnding: The ending to the film effectively resets the entire setting of ''Kamen Rider Zero-One''. [[spoiler: Hiden Intelligence and A.I.M.S. (the season's first two introduced factions) are the only ones that survive to the end of both films; albeit at the cost of the Shotrisers, Isamu and the original members of Metsubojinrai. The Kamen Rider Metsubojinrai incident has plummeted relations between man and machine to nearly pre-series levels with ''the government itself'' now poised for renewed crackdown on Artificial Intelligence. The film deliberately leaves out whether Yaiba's speech on how HistoryRepeatsItself gets through to the masses or not, though it makes clear that she and the Solds have [[GenerationXerox inherited Metsubojinrai's will]] - [[HereWeGoAgain framing the same initial conflict between Humans and Humagears up once more with new players]]]].[[note]] The ''Presidents'' special taking place right after also reveals that [[spoiler: The Ark also survived]], [[AllForNothing erasing the entire season's struggles by proxy]].[[/note]]

* Forshadowing: Gai stumbles out of the remains of Zaia Japan, recovers his Thousand Driver and swears he'll be a President again, even if it's a totally different company and walks out of the story. This would later be picked up in ''~Genms~ The Presidents'' .

* BittersweetEnding: The film itself ends on a pretty gloomy note, but in the wider scope of the story of ''Zero-One'' the story ends on this. [[spoiler:Yua loses her powers, but she comes out of alive. Aruto is still alive and so is Is (with her original memories intact). And with both ZAIA Japan and [=MetsubouJinrai.net=] destroyed, Humagears might just have a shot at living in peace.]]

* DownerEnding: [[spoiler:None of the main characters come out in one piece; [=MetsubouJinrai.net=] is finally KilledOffForReal as a consequence of destroying Kamen Rider [=MetsubouJinrai=], all of Yua's Progrisekeys are destroyed (thus permanently denying her access to Valkyrie), and Fuwa is critically wounded dealing the finishing blow, possibly dying at the film's end as well. Aruto, Is, and Gai are now the only main characters in the series to survive its events while also retaining their powers]].

* TrailersAlwaysLie: Yua's appearances in the film's teasers were framed as though the movie would espouse on her background. A {{Flashback}} snaps to her old university...[[spoiler: [[BaitAndSwitch whereupon she listens to her university teacher talk about his own background instead]]; [[MyGreatestFailure specifically his role in A.I.M.S.' weapon-development]]]].

* SurprisinglyRealisticOutcome: One cannot end prejudice with prejudice. Kamen Rider Metsubojinrai's [[spoiler: plan to become a HateSink for [[GenghisGambit Humanity and Humagears to unite against by destroying the other factions]]]] completely backfires. The Rider's rampage only gets a bunch of people killed and [[IncitingIncident damages the already-frail truce between man and machine]] by [[spoiler: [[NiceJobBreakingItHero giving the government brand-new incentive to crackdown on artificial Intelligence again afterward]]]]. Yua's pre-credits speech is the ''only'' indicator of [[HopeSpot any impending change whatsoever]]; for better or worse deliberately left vague.

* SurprisinglyRealisticOutcome: One cannot end prejudice with prejudice. Kamen Rider Metsubojinrai's [[spoiler: plan to become a HateSink for [[SuicideByCop Humanity and Humagears to unite against]] ([[AmbiguousSituation assuming Fuwa was right about its intent]]]]) completely fails. The Rider's actions only shatter what co-existence there already was and [[spoiler: [[NiceJobBreakingItHero gives the government new incentive to crackdown on artificial Intelligence again by the end]]]]. Yua's pre-credits speech is the ''only'' indicator of [[HopeSpot any impending change whatsoever]]; for better or worse deliberately left vague.

* PosthumousVillainVictory: Lyon Arkland (the BigBad of the previous film) dies without being able to mass-produce the [[RobotSoldier Solds]] he wanted to enter the global arms-race with. He DID however [[spoiler: accomplish his goal of turning the members of Metsubojinrai into the engineered threat he wanted said Solds to fight, claiming the lives of most of the heroes by proxy of the [[TheBerserker insane]] MechanicalAbomination [[GoneHorriblyRight said threat became doing it for him here]]. For bonus points, [[ShootTheShaggyDog the entire incident sours the relations between man and machine the heroes have been fighting to establish all season]], with ''the government itself'' planning to crack down on A.I.]].

* ResetButtonEnding: The ending to the film effectively resets the entire setting of ''Kamen Rider Zero-One''. [[spoiler: Hiden Intelligence and A.I.M.S.

* AllForNothing: By the end of the movie, not much has changed from when the series first started, and what has changed has changed for the worse. [[spoiler:The public at large is still disdainful towards Humagears (for not entirely unjustified reasons), Lyon Arkland [[TheBadGuyWins technically wins]] [[PosthumorousVillainVictory even though he died]], the reformed [=MetsubouJinrai.net=] utterly failed in their quest to prevent another Ark from rising and the ''~Genms~ The Presidents'' special set immediately after reveals the original Ark is still active.]]

* PosthumousVillainVictory: Lyon Arkland (the BigBad of the film before it) dies without being able to mass-produce the [[RobotSoldier Solds]] he wanted to enter the global arms-race with. He DID however [[spoiler: accomplish his goal of turning the members of Metsubojinrai into the DesignatedVillain he wanted said Solds to fight and claimed the lives of most of the heroes by proxy of the [[TheBerserker insane]] MechanicalAbomination he inadvertently transformed the four into doing it for him. For bonus points, the entire incident sours the relations between man and machine the heroes had been fighting to establish all season, with ''the government itself'' planning renewed crackdown on Artificial Intelligence]].

* ResetButtonEnding: The ending to the film effectively resets the entire setting of ''Kamen Rider Zero-One''. [[spoiler: The Kamen Rider Metsubojinrai incident is implied to have plummeted relations between man and machine back to pre-series levels while ''the government itself'' is now poised for renewed crackdown on Artificial Intelligence. The film deliberately leaves out whether Yaiba's speech on how HistoryRepeatsItself gets through to the masses or not, though it makes clear that she and the Solds have [[GenerationXerox inherited Metsubojinrai's will]] - [[HereWeGoAgain framing the same initial conflict between Humans and Humagears up once more with new players]]]].[[note]] The ''Presidents'' special taking place right after also reveals that [[spoiler: The Ark itself has survived]], [[AllForNothing erasing the entire season's struggles by proxy]].[[/note]]

** Subverted with the final scene. The film ends with the defense secretary Shigeru Daimonji gloating to a group of reporters on how A.I. shouldn't have been given free will to resounding cheers....[[spoiler: until Yua and the Solds enter the room and talk about how HistoryRepeatsItself]].
