History Series / KamenRiderDenO

* VillainProtagonist: All of the Taros (minus [[TokenGoodTeammate Kin]]) start out as this.

*** '''Plat Form''' ([[JustForPun geddit?]]): The base form of the Aura Armor, used when Ryotaro is acting on his own without any Imagin. Almost useless in a fight ([[JokeCharacter but it doesn't stop Ryotaro from trying and get his ass kicked though]]).

* ''Kamen Rider Den-O: Singing, Dancing, Great Training!!'': A DVD special distributed by ''Televi-kun'' magazine. Ryotaro and the Taros start an exercise program to get stronger when some evil Imagin crash the party.

* FourIsDeath: Played for laughs with Momotaros, who [[CallingYourAttacks calls his attacks]] "My Special Attack, part [insert number here]!"...but when he does this the fourth time, he skips straight to 5.

While Den-O's base form ([[{{Pun}} Plat Form]]) is incredibly weak, Ryotaro can relinquish control of his body to an Imagin who has possessed him and power up. His first Imagin, a HotBlooded BoisterousBruiser called Momotaros, transforms Den-O into the red Sword Form. Together, TheyFightCrime.

* {{Retcon}}: The ''Chō Den-O Trilogy'' changes the rules on Imagin time travel from the show, now saying that if an Imagin successfully travels to the past, the act will destroy the contractor's past self (via dissolution into sand), whereas in the show proper the Imagin simply emerged from their contracted human without any effect until they started wrecking the past. Unless this is some sort of fallout from the final episode, [[UnfortunateImplications this reflects rather badly on Kintaros, as he was one of the Imagin who completed his contract and travelled back in time]].

*** '''Super Climax''': [[UpToEleven Even more powerful than Climax Form]], at the cost of fusing with [[TheFriendNobodyLikes Sieg]]. This one only appears in spinoff movies.

%%* AnimeThemeSong

Despite average television ratings, ''Den-O'' proved to be a massive hit in Japan, spawning multiple character song [=CDs=], a {{spinoff}} anime starring [[EnsembleDarkhorse the Imagin]] and '''eight''' [[TheMovie movies]], which is practically unheard of for a series that was only designed to last a year:

* ''Film/OOODenOAllRidersLetsGoKamenRiders'': The final movie where ''Den-O'' characters have a starring role (though they'd continue to make appearances in franchise-wide crossovers), although, differently from ''Climax Deka'' and ''Onigashima Warship'', the other titular stars are main characters too. This time around sees the [=DenLiner=] crew, led by New Den-O, team up with ''Series/KamenRiderOOO'', ''Series/KamenRider 1'' and ''[[Series/KamenRider Kamen Rider 2]]''. All main Riders and also many secondary Riders also appeared for the series' 40th year MilestoneCelebration.

Voted #1 series in the Heisei era, and #1 product overall in NHK’s All Kamen Rider Popularity Ranking.

Voted #1 series in the Heisei era, and #1 overall in NHK’s All Kamen Rider Popularity Ranking.

The plot thickens when Ryotaro discovers that Yuuto Sakurai, his sister's missing fiance, is hiding in the past for reasons unknown, and somehow linked to the Imagin attacks. Just as Ryotaro goes to confront him, he is stopped by none other than [[WhichMe a younger version]] of Yuuto Sakurai. This version of Yuuto is brash and cocky, bringing with him his ''own'' Time Train called [=ZeroLiner=] and the ability to transform into [[TheRival Kamen Rider Zeronos]].

* ''Kamen Rider Den-O & Kiva: Climax Deka'': Set after the series, this movie sees Team [=DenLiner=] setting up a detective agency when a rogue Imagin, Negataros, steals the Owner's Liner Pass and begins forming an evil organization. Nominally a CrossOver with ''Series/KamenRiderKiva'', the "crossover" is limited to a couple of brief scenes featuring Wataru and a BigDamnHeroes appearance by Kiva near the end of the final battle.

* VictimOfTheWeek: Common for Franchise/KamenRider, to the extent that future series like ''[[Series/KamenRiderDouble Double]]'' and ''[[Series/KamenRiderOOO OOO]]'' have adopted it. Even the multitude of Den-O movies uphold this tradition, so much that some unexpected examples turn up ([[spoiler:young Ryotaro in ''Ore Tanjou'', young Yuuto in ''Onigashima Battleship'', and even ''G Den-O'' in ''Chou Den-O Episode Yellow''.]])

* ContinuitySnarl: In episode 39 of the series, Yuto is shown as a high-schooler in 1993. However, in the ''Series/KamenRiderDecade'' crossover film ''The Onigashima Battleship'', he's shown to be 10 years old. While this ''could'' be written off as an AR version, it's established that Decade visits Den-O's home series, not an [=A.R.=] version of the show.

** The two main Riders: Ryoutarou uses [[UsefulNotes/JapanesePronouns “boku”]] and Yuuto uses “ore”. Ryoutarou is mild-mannered, even-tempered, usually non-confrontational, and generally more polite. In contrast, Yuuto is hot-headed, rougher, and more willing to pick a fight. This choice of pronouns also suit their SensitiveGuyAndManlyMan dynamic.

*** Momotaros, Kintaros, and Deneb use “ore”. Momotaros is without a doubt the most HotBlooded and least bothered with manners of the cast. Kintaros has the personality of a manly samurai and is the physically strongest of Ryoutarou’s Imagins. Oddly averted for Deneb, though, as he is one of the nicest members of the cast despite using “ore”.
*** Urataros and Ryuutaros use “boku”. Urataros is smooth, well-spoken, and a charismatic speaker, and his choice of “boku” immediately contrasts Momotaros’s “ore”. Meanwhile, Ryuutaros is the most childish of the cast, so him using “boku” emphasizes his child-like personality.

* FunnyBackgroundEvent: Usually inside the [=DenLiner=], especially with Naomi and Ryuutaros.

* InterfaceSpoiler: A non-video game example, oddly: the [[TransformationTrinket henshin belt]] has 4 buttons on it, indicating that Ryotaro will have 4 different Imagin possessing him for different forms, even ColorCodedForYourConvenience so you know that those all-yellow and all-purple Imagin are gonna be part of the crew. [[spoiler: And then Sieg comes in to give him a fifth form, subverting it partially since it's rarely used. Deneb is also shown able to use the system when he possesses Kotaro, giving a form that's similar to Zeronos' own Vega Form.]]

* RetCon: The ''Chō Den-O Trilogy'' changes the rules on Imagin time travel from the show, now saying that if an Imagin successfully travels to the past, the act will destroy the contractor's past self (via dissolution into sand), whereas in the show proper the Imagin simply emerged from their contracted human without any effect until they started wrecking the past. Unless this is some sort of fallout from the final episode, [[UnfortunateImplications this reflects rather badly on Kintaros, as he was one of the Imagin who completed his contract and travelled back in time]].

* ThrowTheDogABone: Ryuutaros meeting Airi ''for real'' in ''Climax Deka'' and even receiving a bento lunch from her.

* TrickedOutTime: When Ryoutaros or the Taros change time, the owner allows it so long as [[CloseEnoughTimeline things don't change too much]]. Thus, most of Ryotaros' travels to the past end up with him helping the VictimOfTheWeek with their issues by changing the past just that tiny bit.

* ''Cho Kamen Rider Den-O & Decade Neo Generations: The Onigashima Warship'': The first in the ''Cho Den-O'' film series, this movie ties directly into the Den-O arc of ''Series/KamenRiderDecade'' and sees the [=DenLiner=] crew, with brief support from Tsukasa Kadoya/Decade, battling a pair of Oni brothers/rogue Kamen Riders who seek to uncover a legendary and powerful battleship. Also features nominal cameos by ''[[Series/KamenRiderKiva Kiva]]'' characters (something of a nod to ''Climax Deka'', also supposedly answering a few continuity issues with the aforementioned Decade) as well as Riders from ''[[Series/KamenRiderAgito Agito]]'', ''[[Series/KamenRiderRyuki Ryuki]]'' and the ''[[Series/KamenRiderKabuto Kabuto]]'' NonSerialMovie summoned up by Decade's rival Daiki Kaito/Diend.

* ''OOO, Den-O, All Riders: Let's Go Kamen Riders'': The final movie where ''Den-O'' characters have a starring role (though they'd continue to make appearances in franchise-wide crossovers), although, differently from ''Climax Deka'' and ''Onigashima Warship'', the other titular stars are main characters too. This time around sees the [=DenLiner=] crew, led by New Den-O, team up with ''Series/KamenRiderOOO'', ''Series/KamenRider 1'' and ''[[Series/KamenRider Kamen Rider 2]]''. All main Riders and also many secondary Riders also appeared for the series' 40th year MilestoneCelebration.

* {{Mondegreen}}: At one point, near the end of episode 10, Owner says "Ladies and gentlemen, [[GratuitousFrench madam et monsieur]]". Takenoko, a translator from the fansub group TV-Nihon, misheard the second part as "Banana new shoe", which has since then become a minor meme.

*** '''Rod''': Possessed by Urataros. Has [[StoneWall high defense but low offense]]. This form is [[OlympicSwimmer good for aquatic combat]], and the [=DenGasher=] rod mode has [[YouWillNotEvadeMe the power of capturing an escaping enemy]].

->''"The train of time, [=DenLiner=]. Will its next stop be the past? Or the future?"''

!!''Kamen Rider Den-O'' provides examples of the following tropes:

%%* AnimeThemeSong
* ArcWords:
** "The past should give us hope."
** "Climax Scene" for the episodes leading into the first movie, [[spoiler:which, in the "aftermath episode", also brings us the '''Climax''' Form.]]
* AnimeHair: Any time an Imagin possesses a human, their hair will be restyled and gain at least a shock of a new color; rarely, an accessory may be included, such as Sieg's feathered boa or Urataros' glasses. The style, color and accessories are consistent across hosts, but oddly never appear on the Imagin themselves.
* BadassFamily: The Nogami family, giving us two Den-[=Os=] (Ryotaro and Kotaro), [[spoiler:Zeronos/Yuto, and BadassNormal Hana]]. Airi, not so much, but hey.
* BeCarefulWhatYouWishFor: A regular occurence with evil Imagin. They'll take their victim's wish and take heavy liberties with it, usually taking the interpretation that causes the most destruction.
* BigBudgetBeefUp: The last few eps.
* BiggerIsBetter: The Onigashima Battleship is '''huge'''. Comparing it to the [=DenLiner=] is like comparing [[Series/GoseiSentaiDairanger Daijinryu]] to a normal Zord. [[SubvertedTrope However]], the [=DenLiner's=] size and speed proves to be a major asset, allowing it to evade most of the shots fired at it and enter the battleship.
* {{Blipvert}}: [[spoiler:Kai]] can dig into people for their memories, which turn out looking like this.

* TheMovie: ''Den-O'' has '''eight''' feature length films (three of which premiered as an anthology), with the most recently-announced as a MilestoneCelebration for 40 years of ''Franchise/KamenRider''.
* MultiformBalance:
** Den-O's forms are tied to which allied Imagin is [[DemonicPossession possessing him]] at the moment:
*** '''Plat Form''' ([[JustForPun geddit?]]): The base form of the Aura Armor, used when Ryotaro is acting on his own without any Imagin. Almost useless in a fight ([[JokeCharacter but it doesn't stop Ryotaro from trying and get his ass kicked though]]).
*** '''Sword''': Possessed by Momotaros. This is the [[JackOfAllStats balanced form]].
*** '''Rod''': Possessed by Urataros. Has [[StoneWall high defense but low offense]]. This form is [[OlympicSwimmer good for aquatic combat]], and the [=DenGasher=] rod mode has [[YouWillNotEvadeMe the power of capturing an escaping enemy]].
*** '''Ax''': Possessed by Kintaros. [[MightyGlacier Slow but strong]], and has [[SuperToughness the best defense]].
*** '''Gun''': Possessed by Ryutaros. [[LightningBruiser Faster than Sword Form and armed with a powerful DenGahser gun mode]]. Ryutaros also incorporates break dancing into his fighting style, making it [[ConfusionFu hard to predict]]. However, Ryutaros's trigger-happy carelessness tends to cause serious collateral damage.
*** '''Wing''': Possessed by Sieg. [[LightningBruiser Even faster than Gun Form]] and armed with [[DualWielding a combination of a boomerang and a handaxe]]. But Sieg is the SixthRanger of the group, often not available, and [[TheFriendNobodyLikes the team loathe him]]. His arrogant attitude also makes him prone to making mistakes in battle. Generally exclusive to movie appearances, though it made a couple teaser appearances in the series beforehand.
*** '''Climax''': [[AllYourPowersCombined Combines powers of the four Taros into one form]]. This form requires a [[TransformationTrinket Climax Cellphone K-Taros]], and all four Taros need to work together controlling a single body.
*** '''Super Climax''': [[UpToEleven Even more powerful than Climax Form]], at the cost of fusing with [[TheFriendNobodyLikes Sieg]]. This one only appears in spinoff movies.
*** '''Liner''': After some CharacterDevelopment, Ryotaro can use the [[CoolSword DenKamen Sword]] to transform into this form without being possessed by Imagin. It's the fastest form and relatively stronger than most, except Climax Form. The downside is Ryotaro's low combat skill, which is remedied to a degree as he can select one of the Taros to advice him through the [=DenKamen Sword=], allowing him to [[DittoFighter utilize their fighting style depend of the situation]].
** [[TheLancer Zeronos]]:
*** '''Altair''': His default [[JackOfAllStats balance form]]. Also, Deneb is independent from Zeronos in this form and can assist him otherwise.
*** '''Vega''': Fused with Deneb. Becomes [[MightyGlacier slower but stronger]] as well as gaining [[SuperToughness improved defense]] and being equipped with a powerful set of {{Shoulder Cannon}}s.
*** '''Zero''': Transformed by using the Red Zeronos card. [[LightningBruiser Marginally weaker than Vega Form but much faster than Altair Form]] and equipped with a powerful Denebick Buster gun (which can qualify as both {{BFG}} and GatlingGood).

* VictimOfTheWeek: Common for Franchise/KamenRider, to the extent that future series like ''[[Series/KamenRiderDouble Double]]'' and ''[[Series/KamenRiderOOO OOO]]'' have adopted it. Even the multitude of Den-O movies uphold this tradition, so much that some unexpected examples turn up ([[spoiler:young Ryotaro in ''Ore Tanjou'', young Yuuto in ''Onigashima Battleship'', and even ''G Den-O'' in ''Chou Den-O Episode Yellow''.]])
