-->'''Gokai Red:''' Each and every Rider... I will defeat!\\
'''Kamen Rider Decade:''' In that case, each and every Sentai... I will defeat.

''Franchise/KamenRider Franchise/SuperSentai: Super Hero Taisen'' is a film (released April 21, 2012) that pits Toei's two most prominent {{Toku}} franchises against one another in a giant CrossOver battle. [[Series/KaizokuSentaiGokaiger Captain Marvelous, AKA Gokai Red]], has formed [[LegionOfDoom Dai-Zangyack]] and attacks the Kamen Rider universe, hoping to claim their Grand Powers and the Ultimate Treasure in the Universe, mainly assisted by the freshly renamed [[Series/ChoudenshiBioman Rider Hunter Silva]]. Opposing them is Dai-Shocker, reformed by [[Series/KamenRiderV3 Doctor G]] and again led by Tsukasa Kadoya AKA Series/KamenRiderDecade AKA Great Leader. Meanwhile, Rangers and Riders on both sides of the conflict are left wondering what's going on and why they're even fighting to begin with.

Oh, and it features nearly 300 Rangers, Riders and villains fighting alongside one another.

----
!! This movie contains examples of the following tropes:
* ActingForTwo: Unlike past Rider crossover movies, where professional voice actors were often used to give voices to past characters who lacked their original actors in the new feature, in this movie, in addition to the voice actors, many of the actual main cast members also gave voices to past heroes and villains, with some amusing results.
** Diend - Apollo Geist
** Gokai Blue - [[Series/JukenSentaiGekiranger Geki Red]]
** Gokai Yellow - Geki Yellow
** Gokai Green - Series/KamenRiderX
** Gokai Silver - [[Series/EngineSentaiGoOnger Go-On Red]]
** Series/KamenRiderOOO - Series/KamenRiderFaiz
** Although he's a professional voice actor, Creator/TatsuhisaSuzuki, who voices [[Series/TokumeiSentaiGobusters Usada Lettuce]], also voices Series/KamenRiderRyuki and [[Series/MahouSentaiMagiranger Magi Red]] in this movie. Fittingly concerning the former, he also voiced Kit Taylor in the Japanese dub of ''Series/KamenRiderDragonKnight''.
** As well as that, Creator/TetsuInada, who has been the voice actor for [[Series/KamenRider Kamen Rider 1]] since ''[[Film/KamenRiderDecadeAllRidersVsDaiShocker All Riders vs. Dai-Shocker]]'' in 2009, also voices Deka Red, which is interesting considering he is known for voicing Doggy Kruger in ''Series/TokusouSentaiDekaranger''. Ironically, at one point during the movie, Deka Red is Rider Kicked by Rider 1.
* AllYourBaseAreBelongToUs: Dai-Zangyack launches an attack on Amanogawa High School specifically to bring out Fourze so they can defeat him.
* AttackOfThe50FootWhatever: Big Machine
* AwesomeYetImpractical: Don't misunderstand, having 200+ stunt actors to get in the suits and have at least one screen appearance is an amazing fest. However, action scenes can't include all of them fighting at once and admittedly it takes a lot of money to do this in the first place so they probably couldn't do it even if they had the time.
* BackFromTheDead: A shed load of villains from both Kamen Rider and Super Sentai, as this movie features the return of Dai-Shocker and the introduction of Dai-Zangyack. Though admittedly Dai-Zangyack's range of villains is far less diverse than Dai-Shocker, while the latter has many villains from both the Showa and Heisei eras, Dai-Zangyack mostly has villains from the past few years and only two Showa villains, though it helps that one of them ([[Series/ChoudenshiBioman Rider (nee Bio) Hunter Silva]]) becomes the top dog of Dai-Zangyack. Literally every single villain in this movie, whether they are from Dai-Shocker or Dai-Zangyack, has been brought back from the dead (with the exception of Dai-Shocker's [[Series/KamenRiderV3 Doktor G]], [[spoiler:since he's actually [[Series/KamenRiderDecade Narutaki]] in disguise]]; also not counted is [[spoiler:Kamen Rider Diend, who is just an AntiHero who decided to be a dick at the end]])
** An interesting case occurs when Joe and Don with [[Series/KamenRiderDecade Daiki]] and [[Series/KamenRiderOOO Hina]] travel via the [[Series/KamenRiderDenO DenLiner]] to 1976, the days of ''Series/HimitsuSentaiGoranger'', where they encounter Baseball Mask, the MonsterOfTheWeek of Gorenger #53, witnessing his destruction at the hands of Akaranger ([[spoiler:actually a Gokai Changed Gokai Red who is also trying his best Akaranger voice impression]]). This is not a depiction of his original demise, so he must have been brought back to be killed a second time.
* BigBad: Starts out as an Ensemble between Tsukasa and Marvelous, but [[spoiler:it's really a Duumvirate between Narutaki/the fake Doktor G and Silva.]]
* BigBadassBattleSequence
* TheCameo: Ryosuke Sakamoto, Yudai Chiba, Asaya Kimijima and Hiroaki Iwanaga provide voiceovers for their characters ([[Series/ChoudenshiBioman Red One]], [[Series/TensouSentaiGoseiger Gosei Red]], [[Series/KamenRiderOOO Kamen Rider Birth and Birth Prototype]] respectively), but don't appear out of costume.
* ColourCodedForYourConvenience: [[spoiler:The Gokaigers change into their respective colors or the closest match when using OOO's combos. Which means that, for better or worse, Gai gets the gray [=SaGoZo=] MightyGlacier form, while the purple [=PuToTyra=] SuperMode goes to ''Ahim''.]]
* CombiningMecha: [[spoiler:Dai-Zangyack and Dai-Shocker combine their spaceships ([[Series/KamenRiderBlackRX Crisis Fortress]] and [[Series/KaizokuSentaiGokaiger Gigant Horse]]) into a HumongousMecha simply called "Big Machine".]]
* CounterpartCombatCoordination: All over the place.
** Series/KamenRiderDecade vs. [[Series/KaizokuSentaiGokaiger Gokai Red]] (PowerCopying)
*** Series/KamenRiderBlade vs. [[Series/JAKQDengekitai Spade Ace]] (PlayingCardMotifs, specifically the Ace of Spades)
*** Series/KamenRiderHibiki vs. [[Series/BattleFeverJ Battle Japan]] ([[MusicalAssassin combat]] [[DanceBattler artists]] based on Japanese culture)
*** Series/KamenRiderRyuki vs. [[Series/JukenSentaiGekiranger Geki Red]] (animal summoning, specifically TigerVersusDragon)
*** [[spoiler:[[Series/KamenRider Kamen Rider #1]] vs. [[Series/HimitsuSentaiGoranger Aka Ranger]] (FirstInstallmentWins)]]

** Decade vs. Series/TensouSentaiGoseiger (CardsOfPower)
* DemotedToDragon: Major villains playing second fiddle to a Rider and a Sentai warrior?
* DemotedToExtra: The initial press release stated that around 200 Sentai warriors will be featured in the movie, implying that all the heroes who were in ''199 Heroes'' were going to be in it alongside the initial ''Go-Busters'' roster. However, the final lineup of Rangers was reduced down to 173. None of the {{sixth ranger}}s and other extra heroes were featured with the exception of Gokai Silver and some of the [[ThreePlusTwo non-sixth extras]] were missing as well (specifically [[Series/NinpuuSentaiHurricaneger the Gouraigers]], [[Series/BakuryuuSentaiAbaranger Abare Black and Abare Killer]]; [[Series/JukenSentaiGekiranger Geki Violet and Chopper]] also make cameos in a flashback and in the background during the final fight when Den-O Rod Form, Den-O Gun Form and Den-O Ax Form trip into a puddle). On the other hand, [[SpotlightStealingSquad the number of Riders was increased from the initial 40 to 50]].
** [[JustifiedTrope Justified Trope]]: Every one of those suits requires a person in a suit, making it a logistical and money challenge. Also, even with reducing Sentai's numbers and adding to Rider's numbers, all pictures of all the heroes still have the Sentai out number the Riders. Toei just made the numbers more even, or as even as possible when one show has a new FiveManBand or at least a PowerTrio for almost every one of its 35 years and another only got one hero per series until very recently and even then rarely getting to 5 Riders or more.
** One of the most notable ones in the villain side is probably the Black Cross King from ''Series/HimitsuSentaiGoranger'' and ''Film/GokaigerGoseigerSuperSentai199HeroGreatBattle''. He goes from being the first main villain of the Super Sentai franchise and the main villain of a movie where almost all Super Sentai powers needed to be used to defeat him to just a minor Dai-Zangyack general without much importance to the story [[spoiler:who's defeated by Series/KamenRiderDouble and Kamen Rider Accel]] in a DeletedScene (thus, all he does in the final film is, uhhh, stand around). Meanwhile, the first villain of the ''Kamen Rider'' franchise, the Great Leader, is represented here by one of the protagonists, Series/KamenRiderDecade, who is the nominal leader of Dai-Shocker and yet again takes the name Great Leader.
* EvilVsEvil: Dai-Zangyack vs. Dai-Shocker.
* FakeShemp: Inevitable, even before one takes into account the actors who [[AuthorExistenceFailure died]], retired from acting, or are too busy.
* HijackedByGanon: Inverted. [[spoiler:In a movie with Akudos Gil, the Black Cross King, and Narutaki, the one piloting Big Machine is '''Diend'''.]]
** [[spoiler:Well, at least Narutaki is part of the Big Bad Duumvirate. But the other member? '''Silva'''.]]
* JerkAss: '''Diend.''' He takes it to the next level by [[spoiler:stealing and piloting the Big Machine...simply because he feels emotionally betrayed by Tsukasa who didn't inform him of his gambit beforehand.]]
* JerkassHasAPoint: Many were shocked at Diend's turn towards the end of the movie, but it is understandable he would want to get back at Tsukasa and Marvelous, he did have a point. Compared to Joe who went from being at the point of tears after being betrayed by Marvelous, charging at him with his sword practically screaming in anger at him to, literally six minutes later after the truth was revealed, scolding Marvelous as if he drew a moustache on his face while he was asleep.
* LeaningOnTheFourthWall: When the Go-Busters first see the old ''Kamen Rider'' minions, Yoko says that they look "dated".
* LegionOfDoom: Dai-Shocker returns from ''Series/KamenRiderDecade'' (with a few additions like [[Series/KamenRiderV3 Doctor G]], [[Series/KamenRiderKuuga N-Daguba-Zeda]], the [[Series/KamenRiderDouble Weather Dopant]], [[Series/KamenRiderBlack the original Shadow Moon]] and the [[Series/KamenRiderOOO Greeed]]); the Super Sentai side has Dai-Zangyack, which includes [[Series/KaizokuSentaiGokaiger Warz and Akdos Gil]], [[Series/TensouSentaiGoseiger Brajira]], [[Series/JukenSentaiGekiranger Long]], [[Series/SamuraiSentaiShinkenger Chimatsuri Dokoku]] and [[Series/ChoudenshiBioman Bio Hunter Silva]].
* LetsYouAndHimFight: Unlike [[InNameOnly past "Vs." movies]], this one will actually pit the Riders and Rangers against one another.
* LoadsAndLoadsOfCharacters: Doesn't even need to be said, at this point.
* MacGuffin: Marvelous is after [[spoiler:the Best Treasure in the Kamen Rider Universe]], and needs the Greater Powers of the Kamen Riders to acquire it.
* [[MassiveMultiplayerCrossover Massive Multiplayer]] CrisisCrossover
* MeaningfulRename: Bio Hunter Silva becomes "''Rider'' Hunter Silva" due to his new role as an enemy of the Riders.
* MesACrowd: Much like in the mecha fight in ''Film/GokaigerGoseigerSuperSentai199HeroGreatBattle'', Brajira battles OOO and the Births in four of his established forms at once (His ''Goseiger vs. Shinkenger'' form is sitting out the movie this time).
* MindScrew: The film's very premise, out of ''and'' InUniverse. Nobody except Tsukasa and Marvelous seems to know why they're fighting. This causes [[Series/KamenRiderDecade Kaitou]], [[Series/KamenRiderOOO Hina]], [[Series/KaizokuSentaiGokaiger Joe and Don]] to join forces and try to figure out what's going on.
* MythologyGag:
** Although there is no InUniverse reference to the events of the [[Series/SamuraiSentaiShinkenger World of Shinkenger]] crossover in ''Decade'' which was the previous -- and first ever -- Sentai/Rider team-up, there are a couple of nods. Marvelous transforms into Shinken Red during his fight with Diend!Kaitou. Aside from that, one of the many revived monsters in the Shocker-Zangyack Alliance is Chinomanako, the Ayakashi that became the BigBad in the World of Shinkenger arc after he stole Daiki's Diendriver, he only appears in the background but can be noticed at one point during the big battle getting beaten up by ''Series/KamenRiderAmazon''.
** In the ''Super Hero Taihen'' net Movies, the two Murder Mystery movies end with Series/KamenRiderFaiz using his Faiz Driver to [[MundaneUtility call ahead for dinner reservations]]. This is precisely what happened during the Series/KamenRiderDecade stageshows.
** The Rider/Sentai teamups in the movie are all nods to the SuperHeroTime block itself, pairing up the shows that are running back-to-back during their time, like Hibiki and the Magirangers, Kiva and the Go-Ongers and even a pre-Super Hero Time example (Black with the Maskmen).
** Decade personally defeating the Goseigers is, on top of the card-themed CounterpartCombatCoordination, also a subtle nod to the ''Super Sentai Dice-O'' trading card arcade game, which debuted alongside ''Goseiger'', being a blatant ''Sentai'' counterpart to the ''Kamen Rider Ganbaride'' trading card arcade game, which debuted alongside ''Decade''.
** When the remaining heroes travel to the past via [=DenLiner=], Owner mentions that the Kamen Riders lost "that slot" to the Super Sentai and the Super Sentai wouldn't have existed without "that slot". "That slot" is the original timeslot the Kamen Rider series had before ''Goranger'' came on and replaced it.
* NeverTrustATrailer: The trailers and other promotional material suggested that it would be a big ol' slugfest of massive proportions between the complete forces of Riders and Rangers with Fourze and the Go-Busters as the frontliners. The actual plot can be best described as "''Kaizoku Sentai Gokaiger vs. Kamen Rider Decade''", there's only ''one'' actual army fight between ''some'' Riders and Rangers, and Fourze and the Go-Busters only appear in the first and third acts.
* PowerCopying: Features [[Series/KamenRiderDecade the characters]] [[Series/KaizokuSentaiGokaiger best known for it]] from each franchise.
** [[spoiler:We also have Decade changing into [[Series/KamenRider Rider #1]], his first-ever Showa change.]]
** And some participants copy [[spoiler:''each other's'' powers: Gokaigers with OOO keys, Go-Buster-Oh with Fourze and his Switches, and the various card-based Riders with Gosei cards]].
* [[spoiler:ThePowerOfFriendship]]: what both the Riders and Sentai decide to be the Greatest Treasure in the Universe.
* ThePresentDay: The last 40 minutes of the movie explicitly take place on April 21, 2012 -- the movie's release date.
* PunBasedTitle: The tie-in net movies are mystery stories, with the title ''Super Hero Tai'''hen'''''.
* RagtagBunchOfMisfits: A girl with SuperStrength, a PhantomThief and two SpacePirates working together to investigate things behind the scenes.
* ShoutOut: In Super Hero Disaster #6, when Gai is discussing the name "Ranger", he says "On the other side of the ocean we're called ''Franchise/PowerRangers''".
** In a later episode, after Blue Buster and Gorisaki try in vain to solve the mystery, it turns out that the letter [[spoiler:wasn't a code, but a perfectly straightforward letter...that's asking for ''[[Series/HikoninSentaiAkibaranger Akibaranger]]'' to be made official.]]
* SpotlightStealingSquad: Joe arguably has the most screen time in the film than everyone else.
* StealthPun: Fourze will [[spoiler:be co-piloting Go-Buster-Oh through RH-03, Yoko's mecha]]. Why? Keep in mind what Fourze's HomeBase is called.
* {{Superdickery}}: You've got two purported heroes leading [[LegionOfDoom Legions of Doom]] and picking fights with each other.
* ThereIsNoKillLikeOverkill: [[spoiler:The Go-Busters' HumongousMecha using Fourze's Super Rocket and Super Drill Switches.]]
** [[spoiler:The Gokai Galleon Buster being powered by the OOO Keys.]]
* UnexpectedCharacter:
** [[Series/ChoudenshiBioman Bio Hunter Silva]]'s return after nearly 30 years.
** [[spoiler:Rangers and Riders using each others' powers.]]
* UnexplainedRecovery: It's never explained how all the dead villains got resurrected.
* TheUnfought: Finally subverted for Narutaki, [[spoiler:who takes the form of [[Series/KamenRiderV3 Destron commander Doktor G]], revealing that this and his previous Colonel Zol form are mere disguises rather than true identities. While Narutaki did not assume the [[OneWingedAngel Werewolf form]] of the original Colonel Zol in ''The Last Story'', he does here assume Doktor G's Kani Lazer form, which is actually a whole new costume and much more powerful than the original. In this form, he is seen being easily able to hold off around a dozen Kamen Riders via, you guessed it, lasers. He is only defeated when the Series/TensouSentaiGoseiger lend their new reflect cards to Decade with [[Series/KamenRiderBlade Blade]] and [[Series/KamenRiderRyuki Ryuki]], allowing them to deflect Doktor G's lasers allowing them to [[FinishingMove finish him off with their respective finishers]].]]
* VisualPun: [[spoiler:Fourze Elek States vs. Denzi Red.]] SwordSparks galore!
** When the Gokaigers charge up the Gokai Galleon Buster with the OOO Keys, all subtitles show "Let's make a sh'''OOO'''w of it!".
* WeHaveReserves: Tsukasa delivers a speech to his minions saying (paraphrased): "Your only strength is that you keep coming back no matter how often you're killed, so go out there fully expecting to die and don't give up until all the Rangers are defeated!"
** Which obviously makes him a BadBoss.
* WithOurSwordsScene: [[spoiler:Heroes from each side lend the other their powers: OOO loans the Gokaigers his Core Medals, which turn into Ranger Keys for his six single colored Combo forms, while the Goseigers loan Decade, Blade, and Ryuki their AttackReflector cards in order to battle [[Series/KamenRiderV3 Kani Laser]].]]
* TheWorfEffect: Painfully so; In the first scene Gokai Red manages to go toe-to-toe with almost no effort with the first seven Showa era Kamen Riders. This is the equivalent of a red belt (albeit in 35 different disciplines, though he only uses two here: [[Series/ChoudenshiBioman Bioman's]] Red One and [[Series/NinjaSentaiKakuranger Kakuranger's]] Ninja Red) going against seven veteran black belts.
** ConservationOfNinjutsu in [[StealthPun full]] [[Series/KamenRiderKabuto force]], people.
** Poor Ackdos Gil...six finishing moves to kill him in human size, but [[spoiler:one smack from Big Machine to kill him at giant size?]]
