History Film / KamenRiderXKamenRiderFourzeAndOOOMovieWarMegaMax

* MenDontCry: Gentaro claims that a man is only allowed to cry if he has [[ArsonMurderAndJaywalking lost his wallet]] or been dumped.

* StarCrossedLovers: Gentarō doesn't take it very well when Kengo insists to him that he can't date Nadeshiko because she's basically [[spoiler:a shapeshifting puddle of space slime]]. He changes his mind eventually.

** The montage of the Legendary Seven Riders fighting evil around the world is accompanied by a [[Main/AwesomeMusic badass]] {{Leitmotif}} that is an instrumental, orchestral rock remix of "Fight! Seven Riders", which was their theme song when they appeared in the BatFamilyCrossover finale of ''Series/KamenRiderStronger''. It gets played again when they take on the [[Series/KamenRiderOOO Greeeds]] and [[Series/KamenRiderDouble Dopants]].

* {{Mooks}}: Through their research into the Gaia Memories, O Medals, and Cosmic Energy, as well as their partnerships with the [[Series/KamenRiderDouble Museum]] and Gamou, Foundation X boasts a vast foot soldier army of Masquerade Dopants (with a white suited variant transformed from Foundation X members using Gaia Memories), Waste Yummies, and Dustards. Poseidon also creates his own Waste Yummy army in ''OOO'''s portion by channeling the power of Uva's Core Medals, while in ''Fourze'''s portion Virgo leads a force of Dustards against Fourze and Nadeshiko as a favor from Gamou to Foundation X.

* CoDragons: Solaris and Katal (Suddendath) to Kannagi.

** In the [[ReCut Director's Cut]], Gentaro does his own take on [[Series/KamenRiderStronger Kamen Rider Stronger]]'s trademark [[InTheNameOfTheMoon introduction speech]] before his fight with the Dustards at Amanogawa High.

** It's implied that Foundation X backed the Kougami Foundation's research on Core Medals.
** Shotaro still uses the Lost Driver, though it's unclear if it's [[spoiler:the one left to him by Skull or the one left to him by Philip after his "death"]].

* LegionOfDoom: Foundation X uses the research its agents gathered to build an army consisting of various MonstersOfTheWeek as well as mooks from the three series ''Fourze'', ''OOO'' and ''W'', alongside monsters of the BigBad's own design, called "Mutamids". They're not actually the same monsters from their original series, but it's [[PropRecycling an excuse to reuse monster suits]].

* {{Mooks}}: Through their research into the Gaia Memories, O Medals, and Cosmic Energy, as well as their partnerships with the [[Series/KamenRiderDouble Museum]] and Gamou, Foundation X boasts a vast foot soldier army of Masquerade Dopants (with a white suited variant transformed from Foundation X members using Gaia Memories), Waste Yummies, and Dustards. Poseidon also creates his own Waste Yummy army in OOO's portion by channeling the power of Uva's Core Medals, while in Fourze's portion Virgo leads a force of Dustards against Fourze and Nadeshiko as a favor from Gamou to Foundation X.

* PowerCopying: SOLU is able to copy data from pretty much anything, including devices and people, and can even improve on whatever it copies. [[spoiler:A SOLU sample copying the real Nadeshiko Misaki is how the Nadeshiko who Gentarō meets comes to existence. It's also the reason she can transform her own Driver based on his]], and the [[spoiler:Rocket Super-1 Switch]] is made of SOLU replicating the Rocket Switch and upgrading on it.

* SealedGoodInACan: The Seven Legendary Riders are sealed inside Fourze and OOO's [[TransformationTrinket transformation trinkets]] by Kannagi. 1, 2, V3 and Riderman are trapped within Astro Switches while X, Amazon and Stronger trapped inside Core Medals. They are freed when Fourze and OOO perform a Limit Break and a Scanning Charge respectively.

* SuperMode: OOO's [[spoiler:Super [=TaToBa=]]] Combo and Furze's [[spoiler:Rocket]] States.

* TrashTheSet: Being the finale to ''[=OOO=]'', Cous Coussier is trashed following an attack by Yummies on Eiji and Ankh. Chiyoko tells them [[CrowningMomentOfAwesome that it will open just the same as it always has the next day.]]

!! This movie contains examples of the following tropes:
* AGodAmI: [[spoiler:Lem Kannagi once he becomes the Super Galaxy King]].

** In the [[ReCut Director's Cut]], Gentaro does his own take on [[Series/KamenRiderStronger Kamen Rider Stronger]]'s trademark [[InTheNameOfTheMoonSpeech introduction speech]] before his fight with the Dustards at Amanogawa High.

** In the [[ReCut Director's Cut]], Gentaro does his own take on [[KamenRiderStronger Kamen Rider Stronger's]] trademark introduction speech before his fight with the Dustards at Amanogawa High.

** Not to mention that Shotaro references Eiji's exclamation that "Riders look out for each other" from ''Kamen Rider W Forever''.

** "Anything Goes!", the opening theme song of ''[=OOO=]'', is played as a duet with him and the original vocalist.

* TheMagicComesBack: [[spoiler: At the end of ''OOO'', all of the Core Medals, with the exception of Ankh's personal Core Medal, were thought to have been lost to oblivion in the vortex that destroyed Dr. Maki and the Medal Vessel. In this movie, it's revealed that the Core Medals were sent into the future, where they ended up being absorbed by Michal Minato, turning his Poseidon identity into a SuperpoweredEvilSide. When Poseidon traveled into the past, the Core Medals were with him, allowing Ankh to retrieve them so Eiji may become OOO once again]].

* MenDontCry: Gentaro claims that a man is only allowed to cry if he's [[ArsonMurderAndJaywalking lost his wallet]] or been dumped.

** The Super Galaxy King is a reference to the BigBad of ''Eight Riders vs. Galaxy King'', TheMovie for ''Skyrider'', which had him team up with the same Legendary Seven Riders who appear in this movie. TheDragon to him, Suddendath, is a homage to Suddendas, who was TheDragon to Galaxy King.

** The Rocket Super-1 Switch is a subtle reference to ''Series/KamenRiderSuper1'', who also had an outer space motif like Fourze does.

* PowerCopying: SOLU is able to copy data from pretty much anything, including devices and people, and can even improve on whatever it copies. [[spoiler:A SOLU sample copying the real Nadeshiko Misaki is how the Nadeshiko who Gentarō meets comes to existence. It's also the reason she can transform her own Driver based on his, and the Rocket Super-1 switch is made of SOLU replicating the Rocket Switch and upgrading on it.]]

* TheStarscream: [[spoiler:Lem Kannagi was the head of a Foundation X project to control the world's energy supplies, but he used those resources to instead attempt to conquer the galaxy.]]
* SuperMode: OOO's Super [=TaToBa=] Combo and Fourze's Rocket States.

* TheUnfought: One of the Mutamits, Solaris, briefly demonstrates feline attributes during Foundation X's meeting with Gamō. Unlike Katal, she never assumes her full Mutamit transformation, instead opting for turning into the Unicorn Zodiarts to fight the heroes.

** "Shout Out", the theme song for the "[=ShaUTa=]" Combo, makes its debut in this movie, having never been used in ''[=OOO=]'''s broadcast run, and like all of the other Combo-specific theme songs, is sung by Shū Watanabe. In a subversion, the small portion of the song that plays in this movie does not include lyrics other than the Combo's name sung by Creator/AkiraKushida, the voice of the OOO Driver.

** The montage of the Legendary Seven Riders fighting evil around the world is accompanied by a [[Main/AwesomeMusic badass]] {{Leitmotif}} that is an instrumental, orchestral rock remix of "Fight! Seven Riders", which was their theme song when they appeared in the BatFamilyCrossover finale of ''Series/KamenRiderStronger''. It gets played again when they take on the Greeeds and Dopants.

** When OOO and Fourze are battling the Masquerade Dopants, Waste Yummies, and Stardust Ninja Dustards together, their opening theme songs, "Anything Goes!" and "Switch On!" respectively, play consecutively.

* TrashTheSet: Being the finale to [=OOO=], Cous Coussier is trashed following an attack by Yummies on Eiji and Ankh. Chiyoko tells them [[CrowningMomentOfAwesome that it will open just the same as it always has the next day.]]

* WhyDidItHaveToBeSnakes: Ironically, despite being a water-themed Rider, Michal is hydrophobic. [[spoiler:He manages to overcome it in the end.]]

''Franchise/KamenRider × Series/KamenRiderFourze & [[Series/KamenRiderOOO OOO]]: Movie War Mega Max'' is the third Movie War movie. Premiered in Japanese theatres on December 10, 2011.

In need of the following [[Main/NeedsWikiMagicLove Wiki Magic Love]]:
* Administrivia/NeedsABetterDescription: Short

* Main/PagesNeedingImages

* {{Mooks}}: Through their research into the Gaia Memories, O Medals, and Cosmic Energy, as well as their partnerships with the [[Series/KamenRiderDouble Museu]]m and Gamou, Foundation X boasts a vast foot soldier army of Masquerade Dopants (with a white suited variant transformed from Foundation X members using Gaia Memories), Waste Yummies, and Dustards. Poseidon also creates his own Waste Yummy army in OOO's portion by channeling the power of Uva's Core Medals, while in Fourze's portion Virgo leads a force of Dustards against Fourze and Nadeshiko as a favor from Gamou to Foundation X.

* AllThereInTheManual: The names of Michal's Kamen Rider forms. The evil form that uses core medals is called Kamen Rider Poseidon, and the good form created from the water-powered belt is called Kamen Rider Aqua.
** The name of Michal's jet ski is "Aqua Miraider".

* TheDragon: Solaris and Katal (Suddendath) to Kannagi.

* TimeStandsStill: The Super Galaxy King is able to do this by taping into the power of the time-displaced Core Medals from the future. [[spoiler:OOO can counter this with the Super [=TaToBa=] Combo, whose Medals are also from the future.]]

* TrashTheSet: Being the finale to [=OOOs=], Cous Coussier is trashed following an attack by Yummies on Eiji and Ankh. Chiyoko tells them [[CrowningMomentOfAwesome that it will open just the same as it always has the next day.]]

** The Seven Legendary Riders are battling Foundation X in various countries. Back in the old days, when a Rider's predecessors would always appear in the final arc to help out, where did the guest star Riders say they were coming from? ''Fighting the evil organization's branches in other countries.'' This goes all the way back to the very first series, when Takeshi Hongo - his actor having recovered from the injury that necessitated Hayato Ichimonji's introduction - returned midseries. Fighting Shocker overseas is where he'd been. The only difference is this time we ''see'' the Seven Legendary Riders' overseas battles before they return to Japan to fight alongside the current heroes.

* TheMagicComesBack: [[spoiler: At the end of OOO, all of the Core Medals, with the exception of Ankh's personal Core Medal, were thought to have been lost to oblivion in the vortex that destroyed Dr. Maki and the Medal Vessel. In this movie, it's revealed that the Core Medals were sent into the future, where they ended up being absorbed by Michal Minato, turning his Poseidon identity into a SuperpoweredEvilSide. When Poseidon traveled into the past, the Core Medals were with him, allowing Ankh to retrieve them so Eiji may become OOO once again]].

* MythologyGag: Michal's transformation into Aqua is reminiscent of Kamen Rider #1's previous transformation sequence, but with water and a jet ski instead of wind and a motorcycle.

* WhyDidItHaveToBeSnakes: Ironically, despite being a water-themed Rider, Michal is aquaphobic. [[spoiler:He manages to overcome it in the end.]]

* StarCrossedLovers: Gentarō doesn't take it very well when Kengo insists to him that he can't date Nadeshiko because, she's basically [[spoiler:a shapeshifting puddle of space slime]]. He changes his mind eventually.

* LegionOfDoom: Foundation X uses the research its agents gathered to build an army consisting of various MonstersOfTheWeek as well as mooks from the three series ''Fourze'', ''OOO'' and ''W'', alongside monsters of the BigBad's own design, called "Mutamids". They're not actually the same monsters from their original series, but it's [[PropRecycling an excuse to reuse monster suits]].

* TheCameo: Jun Kazu, the final boss of ''Series/KamenRiderDouble'', appears in archived footage from the reunion special, as does Katsumi Daidō and the memebrs of NEVER, again through archived footage from TheMovie.

** Both crossover cameos in ''Kamen Rider W Forever'' and ''Kamen Rider OOO Wonderful'' are referenced.

* ForHappiness: Shotaro is quick to voice how unimpressed he is with Gentaro - and just as quick to change his mind when he learns they have the exact same motive.
