History Series / KamenRiderDecade

!![[{{Catchphrase}} I'm just a passing through trope. Remember that!]]

* AlternateUniverse: All the worlds visited by Decade to their original shows (except for the ''Shinkenger'' world, the original worlds, and probably Den-O) and within ''Decade'', Kuuga World to Agito World, and RX World to Black World. Agito World has Toko Yashiro, an alternate universe twin of Kuuga World's Ai Yashiro. Agito World also has the Grongi like Kuuga World, a MythologyGag to the original ''Agito'' and ''Kuuga'' being set in the same universe. RX World and Black World have their own, seperate incarnation of Kotaro Minami, both played by original actor Tetsuo Kurata.

* AnyoneCanDie: The Rider War World. Holy hell, the Rider War World. [[spoiler:Ixa, Leangle, Amaki, Todoroki, Blade, and Garren all get killed/removed from existence over the course of Episode 30. In 31, Yusuke bites it against Super Apollo Geist (and is then brought BackFromTheDead in a BrainwashedAndCrazy state), and ''every single AU Rider except for Yusuke'' is erased from reality. Even the main character bites it]].

* KickTheSonOfABitch: If one sees Tsukasa as the villain of the piece (being the "destroyer of worlds" and whatnot), this could be how to describe his destroying the Perfecter as he throws it to Apollo Geist.

Voted #14 series in the Heisei era, and #21 product overall in NHK's All Kamen Rider Popularity Ranking.

* ''Kamen Rider Decade: Protect! The World of Televi-kun'', a ''Televi-kun'' magazine exclusive DVD.

* CrouchingMoronHiddenBadass: Tackle, in the movie. Unlike [[Series/KamenRiderStronger the original Tackle]], this younger AlternateUniverse version of her is a very cheerful ThirdPersonPerson and briefly becomes pretty much the [[Characters/XMen90sMembers Jubilee]] to Tsukasa's ComicBook/{{Wolverine}}. Then she beat seven Riotroopers in one hit and forced a monster to retreat, saving Natsumi and effectively helping to revive Decade, all while [[spoiler: being DeadAllAlong]].

** Rook, one of the more powerful Fangire in ''Kiva'' (and one of ''dozens'' to survive another 22 years after being "defeated"), is taken down in a few slashes by Decade - not even a FinishingMove or otherwise ''special'' slashes. Bishop, who was the BigBad in ''Kiva'', was taken down by an even bigger slash, which ''was'' a FinishingMove.

*** Although, it's justified. It's one of the abilities Tsukasa picked up, like speaking Grongi or playing the violin, when he travels to a new world.

** Amazon had given the Porcupine Grongi another brutal cutdown. In ''Kuuga'', it took Yusuke's [[UnstoppableRage full killing intent]] to slay the Grongi.
*** On the other hand, in the same world, the Ten-Faced Demon demonstrates his DittoFighter status by worfing Kuuga and Faiz!Decade with their own moves. The ''original'' version didn't put up that much of a fight against Amazon by his lonesome!
** Probably the largest example of this comes in the penultimate episode where the Warthog Fangire, whom is one of the more powerful Fangires, is taken down by a single, rather off-handed kick by Decade.
** In the final episode, Tsukasa gets hit with it twice: once against Super Apollo Geist (who also manhandles Kuuga, Hibiki, and Kiva at the same time), and then ''immediately'' afterwards by [[spoiler:Kazuma Kenzaki, the '''original''' Blade in King Form.]] In all fairness to Decade, he couldn't do much against the second foe because Apollo arleady exhausted him right before.

* SuperMode: Decade's Complete Form. Contrary to Decade's usual shtick, this gives him the ability to create copies of his nine predecessors' Super Modes (much like [[Manga/JoJosBizarreAdventure Stands]]) so that he can use their ultimate attacks. In ''The Last Story'', when the actual nine Riders are around, it can also transform them into their super modes (in order when that occurs: [[Series/KamenRiderKabuto Hyper Kabuto]], [[Series/KamenRiderAgito Agito Shining]], [[Series/KamenRiderFaiz Faiz Blaster]], [[Series/KamenRiderHibiki Armed Hibiki]], [[Series/KamenRiderRyuki Ryuki Survive]], [[Series/KamenRiderBlade Blade King]], [[Series/KamenRiderKuuga Rising Ultimate Kuuga]], [[Series/KamenRiderKiva Kiva Emperor]], and [[Series/KamenRiderDenO Den-O Super Climax]]).

** Diend gains his own Complete Form in the Super Den-O Trilogy, which draws its power not from protagonist Riders, but movie-exclusive Riders: [[Series/KamenRiderAgito G4]], [[Series/KamenRiderRyuki Ryuga]], [[Series/KamenRiderFaiz Orga]], [[Series/KamenRiderBlade Glaive]], [[Series/KamenRiderHibiki Kabuki]], [[Series/KamenRiderKabuto Caucasus]], [[Series/KamenRiderKiva Arc]], and [[Series/KamenRiderDouble Skull]]. The only ones not to be bad guys are Skull ([[spoiler: though he's impersonated by a bad guy in Movie Wars 2010.]] Double's ''true'' Movie Dark Rider is Eternal, but of course that movie wasn't out yet) and Orga (between this and Orga being in the World of Negatives it's clear ThePowersThatBe consider him Faiz's Movie Dark Rider, but he was just [[spoiler: Kiba who'd been deceived]]. It ''should'' have been Psyga). [[Series/KamenRiderDenO Gaoh]], who would represent ''Den-O'' isn't present, due to the events of ''Ore Tanjou'' seemingly locking him out of the timeline, thus making ''Den-O'' the only series that Diend's Complete Form doesn't have a representative for[[note]]although Den-O did have other movie-exclusive riders that could have fit the bill, namely Yuuki and Nega Den-O, the reason those riders weren't used are due to the fact that Gaoh was Den-O's summer movie rider, and Diend's Complete form was themed around summer movie-exclusive riders, hence the reason why Ryuga is used instead of Verde, despite the latter arguable being a better fit in terms of personality[[/note]].

* HighSchoolAU: ''Series/KamenRiderFaiz'' turns into one of these.

* ItCantBeHelped: In a stage production, there was a skit about [[Series/KamenRiderFaiz Faiz]], [[Series/KamenRiderKuuga Kuuga]], [[Series/KamenRiderRyuki Ryuki]], [[Series/KamenRiderKabuto Kabuto]], Decade, and Diend being hungry and wanting to get a bite to eat. Decade argues with the other Riders about how there's no time, but Faiz calls in a reservation at [[Series/KamenRiderKiva IXA's]] italian restaurant anyway. [[https://www.youtube.com/watch?v=qwECY4zYR7s Hilarity ensues.]]

* KickTheDog: In ''Agito'' world, Diend commands a summoned [[Series/KamenRiderFaiz Delta]] to Rider Kick [[strike:Decade]] ''Tsukasa''.[[note]]He's not in Rider form because that universe's version of Gills stole his Decadriver.[[/note]] Thankfully, Yusuke was there to stop it.

* ReunionShow: Though most of the characters are [[TheOtherDarrin recast]] or [[SuspiciouslySimilarSubstitute replaced]], a good number of actors returned to reprise their roles, even if they're also AU counterparts. This includes most of the central casts of ''[[Series/KamenRiderDenO Den-O]]'' and ''[[Series/KamenRiderHibiki Hibiki]]'', as well as [[Series/KamenRiderKiva Wataru Kurenai/Kiva and Otoya Kurenai/Dark Kiva]], the Riders from ''[[Series/KamenRiderBlade Missing Ace]]'', Kotaro Minami (as both [[Series/KamenRiderBlack Black]] '''and''' [[Series/KamenRiderBlackRX Black RX]]), [[Series/KamenRiderBlade Kazuma Kenzaki/Blade]], and (in the movie only) [[Series/KamenRiderAgito Shoichi Tsugami/Agito]]. The Riders summoned by Narutaki or Kiva-la (including [[Series/KamenRiderKabuto the Hoppers]], [[Series/KamenRiderFaiz Kaixa]], and [[Series/KamenRiderRyuki Ohja]]) are also voiced by their original actors and are implied to be the real thing. Diend's summons are an odd case, as some have their original actors providing the voice, but seem to just be copies (as evidenced by the fact that a summoned Den-O[=/=]Momotaros has no qualms about fighting Tsukasa after the events of both the Den-O arc and the ''Chou Den-O and Decade'' movie, where they were allies).

** Takumi Ogami ([[Series/KamenRiderFaiz Faiz]]): "Ogami" sounds very similar to "ookami", meaning "wolf" (but with different kanji). Not just a reference to [[spoiler:him being the Wolf Orphnoch]], but a pun on the original version's surname, "Inui", the first two syllables of which would be the Japanese word for "dog" if it was written with different kanji.

* SmugSnake: Apparently it doesn't matter what dimension, AU or parallel existence you're in: Evil!Mutsuki (from ''Blade'') will always be a {{Jerkass}}.
** [[spoiler:As it turns out, though, he and Sakuya were only pretending to be jerks to Kazuma in order to help teach him humility.]]
** So will [[Series/KamenRiderFaiz Kusaka]].

** The World of Faiz has the same situation with the Orphnochs as the ''Series/KamenRiderFaiz'', but moves it to a HighSchoolAU.

** This topic is tackled with a bit more substance in the Faiz world, which is to be expected since it was a major plot focus in [[Series/KamenRiderFaiz the original series]] as well.

* TheResolutionWillNotBeTelevised: A rare ''intentional'' case of this.

* LetsGetDangerous: "I'm a passing Kamen Rider. Remember that. Transform!"

** In Hibiki's world, Tsukasa is wearing a pink kimono, just like [[StreetFighter Dan Hibiki]].

* CrouchingMoronHiddenBadass: Tackle, in the movie. Unlike [[Series/KamenRiderStronger the original Tackle]], this younger AlternateUniverse version of her is a very cheerful ThirdPersonPerson and briefly becomes pretty much the [[Characters/XMen90sMembers Jubilee]] to Tsukasa's {{Wolverine}}. Then she beat seven Riotroopers in one hit and forced a monster to retreat, saving Natsumi and effectively helping to revive Decade, all while [[spoiler: being DeadAllAlong]].
