History Series / KamenRiderDouble

*** [[color:mediumblue:Trial]]: Turns Accel into Accel Trial and a FragileSpeedster. Sacrificing physical strength and armor strength, it increases his speed a hundredfold. However, once the Maximum Drive is activated, it has to be finished [[HourOfPower in under 10 seconds]], elsewise the user's body is harmed. The Maximum Drive is activated through the stopwatch-like Maximum Mode. When in Memory Mode, has a starting-light display with three lights to indicate the different stages of the transformation when it's in.

* TakahashiCouple: Shotaro and Akiko are always at each others' throats but it's been implied a couple times that there might be an underlying attraction.

** In the ''Message for Double'' chapter of ''Movie Wars Core'', a flashback to Narumi Soukichi[=/=]Kamen Rider Skull's OriginStory has him witnessing the original Dopant Memory tests on a bunch of young women. The whole thing is lifted straight out of the women-on-heroin scene in ''EnterTheDragon''.

Together with their landlord and self-proclaimed "chief" Akiko Narumi, they operate the Narumi Detective Agency in the "Windy City", Futo. Their specialty is solving supernatural crimes committed by monsters called [[MonsterOfTheWeek Dopants]], which are created when an ordinary human is transformed by one of the dangerous [[TransformationTrinket Gaia Memories]].

[-Note-]: [-The name of the show in Japanese uses the English letter W and reads it as "''Daburu''"/"Double". Depending on who is subbing the show, the name of the show may be referred to as "Kamen Rider Double" (the English name given in the logo) or "Kamen Rider W" (the literal reading of the show's title).-]

** The ending of ''A to Z'' becomes a BittersweetEnding when we discover later that [[spoiler:Daido and NEVER are actually a bunch of {{Fallen Hero}}s driven mad by a tragedy and not the evil monsters they seemed to be.]]

Shows strong influence from 1972 {{Manga}}-turned-{{Toku}} ''Manga/ChoujinBarom1'', HardboiledDetective fiction, CyberPunk, and mad cap comedy-- making the series as much a matter of fusion as its Rider.

** Accel is also [[DenjinZaboga a red superhero who can turn into a bike]].

** Maybe they were going for "NASCAR Dopant" instead?

** The show itself can be called ''Kamen Rider W'' instead of ''Double''.

** The series itself [[WordOfGod is confirmed by the staff]] to be a homage to the Showa Era, from the little things such as the scarf to the overall feel of the series.

* ActorAllusion: Aya Sugimoto, best known as [[PrettyGuardianSailorMoon Queen Beryl]], appears in TheMovie ''Double Forever: A to Z'' as a Maria S Cran'''berry'''.
** Shotaro threw an epic one in "J's Labyrinth" when he wants to enter a models-only recreation club.
---> '''Guard''': Members only, please. This club is for models only.
---> '''Shotaro''': Haha, that's sweet. ''I'm'' a model. So, ciao.[[note]]After which he tries to enter and immediately pushed back by the guard.[[/note]]
** Also in ''Double Forever'', Elizabeth manages to recover the T2 '''A'''ccel, '''K'''ey, and '''B'''ird Memories, a nod to the fact that her and Queen's actresses are members of the girl group [=AKB48=].
** Episode 45's first two minutes are devoted to reminding us of [[Series/JukenSentaiGekiranger Yuka Hirata's]] previous role by letting her perform her [[{{Tsundere}} extreme tsun-tsun, extreme dere-dere]] schtick.
** Yoshie Gotou, one of the Stage Moms in "The O Chain", actually appeared in Series/KamenRiderKiva as the woman who went into sports archery after her own StageMom pushed her to learn the violin. Karma's the real bitch here.

* FakeNationality: Kazu is played by Korean actor Gong Teyu.

* NamesTheSame: There's a Nasca in the third KeroroGunsou movie. [[spoiler:She's ''also'' an alterego (real name Miruru), with the ability to sprout wings]].
** Was the Taboo Dopant inspired by the BlackEyedPeas?
*** A pity then, that the W isn't for will.i.am...
** And yeah. Saeko Sonozaki. Did she share a name with a certain ''Series/KamenRiderFaiz'' character and had a similar position for the villains?
*** [[HigurashiNoNakuKoroNi Sonozaki]] you say? As an added bonus, Wakana was in a live-action adaptation thereof as Mion.
** Sokichi Narumi, with the white hat and all, brings to mind a certain Sokichi Banba, better known as Big One of ''Series/JAKQDengekitai''.
** One guest in "The F Afterglow" is an ex-thief named Fuyumi Aso, which means she may have relatives [[Series/KamenRiderKiva in another parallel world]].
*** Make that [[Film/KamenRiderZO TWO parallel worlds]].
** 'Fangs' are also tiny self-mobile weapons used by [[Anime/MobileSuitGundam00 Gundam Throne Zwei and Arche Gundam]].
** There also was an Isaka in ''Series/KamenRiderBlade''.
** From "The B Carried on the Wind", Isamu Bitou, much like [[Series/MahouSentaiMagiranger Isamu Ozu]], had been locked away from society for some time (albeit for different reasons). [[spoiler:It's worth noting that [=CycloneJokerXtreme=], who debuts here, carries a sword and shield that slide together, much like Wolzard's did]]. He also has the same family name as [[Series/NinpuuSentaiHurricaneger Kouta Bitou]], [[TwoGuysAndAGirl who also is friends with a guy and a girl,]] though in this case all three are JustFriends (close friends, but still).
** The client from episodes 45-46 is named Kyoko [[Series/KamenRiderHibiki Todoroki]].
** Surprisingly, Shotaro, GenreSavvy that he is, didn't freak out at the fact that his partner's true name is [[spoiler: [[Manga/DeathNote Raito]] [[HigurashiNoNakuKoroNi Sonozaki]]]].
** The Narumi Detective Agency has absolutely nothing to do with [[RaidouKuzunohaVsTheSoullessArmy a certain other one that deals with a certain soulless army.]]
** The client in episode 49 wishes to see his sister [[Series/KamenRiderRyuki Yui]] rescued. They're both someone's sister and in need of rescue constantly, but then again that's kind of a staple female role on Franchise/KamenRider.

* WhatCouldHaveBeen: [[spoiler:"The O Chain" storyline has Shroud mention [=CycloneAccel=] Xtreme, and we even get an ImagineSpot-style image of it, but it doesn't happen and probably never will because it would involve breaking up Shotaro and Philip's partnership as well as fighting with hatred rather than compassion, two things Ryu refuses to do.]]
** [[spoiler: Though we did get [[FanNickname CAX]] in Kamen Rider Climax Heroes [[Series/KamenRiderOOO OOO]].]]

** An [[EvilTwin evil version]] shows up in W Forever A to Z. When [[spoiler:Kamen Rider Eternal uses the T2 Zone Memory for a Maximum Drive, all of the T2 Gaia Memories fly straight for him and place themselves into one of the 26 Maximum Drive Slots, causing a massive power up. Turns the otherwise cool-sounding [[FumihikoTachiki Gaia Memory voice]] into horror when 26 Memory names are said at the same time.]]

** In another "Hardboiled Delusion Diaries" {{omake}}, Magician Akiko's magic show is called "Princess Akiko's [[OjamajoDoremi Magical Stage]]".

** Joker: GoodOldFisticuffs

** Trigger: [[TheGunslinger Handgun]]
** [=CycloneJokerXtreme=]: [[HeroesPreferSwords Sword and Shield]].

** Shotaro: Left half

** Phillip: Right half

** Accel

** Shotaro:

** Phillip:

*** MasterOfNone: Shotaro using the Lost Driver to fight alone with just the Joker Memory. A couple of later tie-in projects have shown Phillip doing the same with the Cyclone Memory.

* MultiformBalance
** Double
*** JackOfAllStats: The Joker forms.[[note]][=CycloneJoker=], [=HeatJoker=] & [=LunaJoker=][[/note]]
*** MightyGlacier: The Metal forms.[[note]][=HeatMetal=], [=LunaMetal=] & [=CycloneMetal=][[/note]]
*** GlassCannon: The Trigger forms.[[note]][=LunaTrigger=], [=CycloneTrigger=] & [=HeatTrigger=][[/note]]

** [[color:maroon:Stag]] Phone: A cellphone with flight and small attacks. Can summon the [=RevolGarry=] and perform a strange pincer blast with the Trigger Magnum.
** [[color:gold:Spider]] Shock: Essentially a watch with a GrapplingHookPistol. Also fires tracking beacons and can shoot webs when connected to the Trigger Magnum in Luna Mode.
** [[color:navy:Bat]] Shot: A digital camera which can place itself virtually ''anywhere'' and reveal invisible opponents with the Luna Memory. Attaching it to the Metal Shaft turns it into the Sonic Shaft, which can shatter objects; and attaching it to the Trigger Magnum allows it to fire a focused, precision shot.
** [[color:silver:Fang]] Memory: A little dinosaur that allows Kamen Rider Double to access his MidSeasonUpgrade: [[color:silver:Fang]][[color:purple:Joker]]. It also serves as Philip's guardian. When attached to the Double Driver, it folds itself into the shape of a dinosaur head.
** [[color:teal:Beetle]] Phone: Accel's cellphone that is the kabutomushi to the Double's Stag Phone's kuwagatamushi. Ryu uses it to spy on Shotaro and Philip at first, then later makes use of it as a cell phone and can remote-control Gunner A with it.
** [[color:green:Frog]] Pod: A CD Player dock for the [=MP3=]-like Frog Memory (read: iPod Shuffle) which records what the Frog Pod hears as a surveillance device.
** [[color:orange:Denden]] Sensor: A pair of nightvision/infrared goggles that turn into a snail with a laser tripwire. Can see ''anything''.

->"''Do you have the courage...to ride with the devil?''"

** First off, he pushes Phillip into a teleportation chamber which puts him in the crystal prison from the beginning of the show, thus causing his mentor to rescue him and get killed for it. [[SubvertedTrope However,]] [[spoiler:this proved to ''help'' Phillip, since things went normally, Narumi, Ryu, and Phillip would have been turned into pawns for Shroud's RoaringRampageOfRevenge]].

* NiceJobBreakingItHero: Shotaro [[spoiler: slips the fact that Phillip died to save Wakana, who then runs off to start the [[AssimilationPlot Gaia Impact]].]] [[SubvertedTrope However,]] [[spoiler: Wakana executes the Gaia Impact, but uses it to revive Phillip. This proved vital when Phillip took an energy bullet for Shotaro.]] So in short, If Shotaro [[spoiler: Didn't say Phillip died to Wakana, ''he'' would have died. Nice Job Fixing It, Hero?]]

*** SerialEscalation: [[GoldenSuperMode CycloneJokerGoldXtreme]]

*** SerialEscalation: [=CycloneJokerGoldXtreme=]

Shows strong influence from 1972 {{Manga}}-turned-{{Toku}} ''ChoujinBarom1'', HardboiledDetective fiction, CyberPunk, and mad cap comedy-- making the series as much a matter of fusion as its Rider.

** Double's asymetrical color scheme is reminscent of ''{{Kikaider}}'', another Ishinomori series. And when in [[color:red:Heat]][[color:blue:Trigger]] form, he has the exact same colors as Kikaider 01.

** The Nasca Memory is shaping up to be one now that [[spoiler:Saeko's using it and unlocked stage 3.]] It has super-speed on level with Accel Trial and can actually outmuscle Xtreme.

* IdolSinger: Not only does Wakana get on the action singing her own theme song "Naturally", but Queen & Elizabeth go on an ''Series/AmericanIdol''-like show called "Fuuuuuutic Idol" (yes, six U's) to perform their song "Love♡Wars" ([[LuckyCharmsTitle yes, with a heart]]). Philip and Shotaro enter the competition as "Masked(Kamen) Singers" but just cover one of the show's theme songs, "Finger on the Trigger".

* ContinuityNod: "The Radio Q" brings back the Victims of the Week from "Don't Llay a Finger on M" and "The S Terror". ''Forever A to Z'' takes this UpToEleven by adding those from "Girl A", "Find the C", "Farewell N", "L on the Lips", "Nightmarish H", "D was Seen", and "Beyond R".

** In an inversion of this trope, the bands that perform the ending themes for the series (Labor Day, Galveston 19, Florida Keys, and Wilma-Sidr) are claimed to be bands from the fictional city of Futo. The only instance of one of the songs existing as part of the story is during the Liar Dopant arc (ep. 23&24) when Shotaro and Philip sing "Finger on the Trigger" for the contest. On the Wind Wave podcasts, only Wakana's show treats the theme songs as being separate from the show. DJ HURRY KENN refers to everything as theme songs.

* IdolSinger: Not only does Wakana get on the action singing her own theme song "Naturally", but Queen & Elizabeth go on an ''Series/AmericanIdol''-like show called "Fuuuuuutic Idol" (yes, six U's) to perform their song "Love♡Wars" ([[LuckyCharmsTitle yes, with a heart]]). Philip and Shotaro enter the competition as "Masked(Kamen) Singers" but just cover one of the show's theme songs, [[{{Defictionalization}} I mean, a popular song on Futo radio]], "Finger on the Trigger".

** Deconstructed in "The Likelihood of the G" with [[{{Hikikkomori}} Kawai Toru]], who's dependent on writing in his notepad because he can't bring himself to speak up, much like [[Series/KamenRiderKiva another Hikikkomori]].
