History WMG / KamenRiderDecade

* This is confirmed by the revelation that Yuusuke [[spoiler:will KILL Decade in the upcoming Double/Decade movie]]
** [[spoiler: He ultimately failed. But Natsumi did it as Kivala. Yes, Natsumi.]]

[[WMG: Decade lost his memory after getting into a fight with Gackt.]]

In the PV for the opening [[http://www.youtube.com/watch?v=FJP0oNPfbEo "Journey Through The Decade"]], toward the end, Gackt shoots a white energy at Decade. That was how Tsukasa lost his memory. Gackt wiped it.

* ''[[TheKhan GAAAAAAAAAAAAAAACKT!!]]'' Gackt is slowly becoming the BigBad of... well, ''everything''!

* Well,[[MermaidMelodyPichiPichiPitch when you lose to a bunch of mermaids that sing you into submission]] as your first go as BigBad, you ether become the Badassest BigBad or you become TeamRocket.
* Actually, the [[http://www.veoh.com/browse/videos/category/action_adventure/watch/v186906538ZAtrmqn# full video]] shows that Gackt was throwing Tsukasa a [=KamenRide=] Gackt card.

*** If that's the case, then Gackt's actions at the end of the [[http://www.youtube.com/watch?v=m6HqjIXNF-Q Stay The Ride Alive PV]] were done with remorse. The card he gave also [[spoiler: powered up the DecaDriver at the cost of Tsukasa's life energy. Which explains why the picture was completly drained. He gave the card to Double to repeat the process.]]

[[WMG: Saban will adapt Series/KamenRiderDecade to air alongside Series/PowerRangersSamurai on {{Nickelodeon}}]]

Would be a world where the other riders existed, but now Fourze, Meteor and Nadeshiko are the only ones left. Meteor is Fourze's senpai as a rider. Instead of the modules and switches of the show, this world's Fourze has the Legend Rider switches, though he does also have access to the Fusion States and a Cosmic States which uses all the Legend Rider switches. If they want to be more referential the Fourze technology can be developed by the same people as Super-1, and the Kyodain of this world can be more like the originals

Yes, Another "Dai-Shocker reverse engineered this" WMG. This time, they RE'd a {{Bokurano}} robot. Hence the title.

''[[Series/KamenRiderDrive Drive]]'': Kamen Ride - Drive (Type Speed), Form Ride - Wild, Technic, Deadheat. Machine Decader supplies the tire for the Drive suit. Decade as Drive can use Drive's existing shift cars with the Shift Brace (modified to match the [=DecaDriver=]). Final Form Ride has Drive transforming into a giant Handle-ken (Steering Sword).

Narutaki is shown to not be too bad of a guy when Decade isn't around and generally only joins villains when Decade is his enemy. Tsukasa did something ''horrible'' to him during his time as [[spoiler:Dai-Shocker's Great Leader]] and now RevengeBeforeReason drives the guy.

''[[Series/KamenRiderGaim Gaim]]'': Kamen Ride - Gaim (Orange Arms), Form Ride - Pine, Ichigo. Final Form Ride would be Gaim transforming into a giant orange that functions like the Watermelon Arms for Decade to pilot. Final Kamen Ride would both be Kachidoki and Kiwami Arms.

For [[Series/KamenRiderWizard Wizard]], Please is added after "_____ Ride" to use magic. Kamen Ride Please - Wizard Flame, Form Ride Please - Land, Water, Hurricane. His Final Form Ride is the Wizard Dragon. Yeah. As in Decade ''pulls out the Dragon Phantom from Haruto's body'', while the body forms the wingtips and tail.

Nickelodeon currently airs Power Rangers Samurai, which is based off SamuraiSentaiShinkenger. One of the more notable episodes was when the Shinkengers team up with Decade, which Saban is trying to get rights for the episode's footage from Toei. Should they be given the go ahead, the Power Rangers would be teaming up with Decade, so Kamen Rider Decade could be well on its way to becoming a new series for Nick. Perhaps ThirdTimesTheCharm...

Remember when the Judge declared the Rider Trial was a logical system? He wasn't talking about the constant in-fighting where the winner would decide the fate of the person on Trial, he was talking about how it would lead into the trial not even taking place at all. Why? One word: Odin. Odin possesses the Time Vent card, roams around waiting for a Rider to fight him, and gives them the card upon defeat. Using the Time Vent card, they could go back in time and, with the evidence they're given during the trial, are able to stop whatever happened in the first place, or mess things up and cause the trial to repeat with different outcomes. And it's inevitable that they ''will'' have to fight Odin, since it's still ThereCanBeOnlyOne and Odin is one of the participants.

[[WMG: The Rider Trial in Ryuki's world is really a Film/TheMinorityReport style setting]]

[[WMG: The Worlds of MaskedRider and Series/KamenRiderDragonKnight are A.R. Worlds.]]

The episodes of Kamen Rider Decade that take place in [[SamuraiSentaishinkenger Shinkenger's world]] are shown to take place in the same universe as SamuraiSentaishinkenger. However, it still has slight differences from what is shown in Shinkenger (i.e. the roll call is different). Thus, all of the differences between the worlds Tsukasa visits and those shown in the original series are due to his very presence altering reality.

[[WMG: One of the "New worlds" (non-heisei worlds like Nega, [=DiEnd=] and [[SamuraiSentaiShinkenger Shinkenger]]) would be [[Series/KamenRiderDragonKnight The World of Knight]]]]

(And if you bring up the argument that ''Masked Rider'' became a ShowWithinAShow in ''Series/PowerRangersTimeForce'', there's still another backdoor: the Rangers' [[Series/PowerRangersDinoThunder connection to]] ''SuperSentai'', which leads to the ''Shinkenger'' crossover in ''Decade''...)
** And here's where I gotta stop you. The Dino Thunder episode in question makes it so that ''SuperSentai'' is a ShowWithinAShow in the Power Rangers universe, and not even the same ''Super Sentai'' we know. It's exposited to be a show a Japanese television studio produced based on news reports of the Dino Thunder Rangers' activity, so all bets are off as to how similar their ''Abaranger'' is to the one ''Dino Thunder's'' based on. This theory is easier to go by with the claim that (as far as I know), ''Time Force's'' ''Masked Rider'' nod doesn't actually ret-con the events of A Friend in Need.

[[WMG: Dai-Shocker reverse-engineered the technology from the [[TensouSentaiGoseiger Gosei World]]]]

Series/KamenRiderFourze: Kamen Ride - Fourze, Form Ride - Elec, Fire, Attack Ride - Rocket, Drill, Launcher, Billy the Rod, Hi-Hack Gun[[note]]The last two are summoned by the respective Form Ride card, but the Attack Ride cards enable Limit Break[[/note]], Final Form Ride (Rocket Drill) and Final Attack Ride[[hottip:**:Decade shoves Fourze's head down, then flings his arms upwards roughly as if doing an UCHUU KITAAAAA but Fourze turns into a HUGE drill-tipped rocket that attaches to Decade's leg and drags him screaming through the enemy]]. The [=DecaDriver=] basically repeats the phrases from the Fourze Driver in its own voice and timing.

[[WMG: Saban will adapt KamenRiderDecade to air alongside Series/PowerRangersSamurai on {{Nickelodeon}}]]

[[WMG: The entire series is ThePlan on the part of [[KamenRiderKuuga Yusuke]], [[KamenRiderAgito Shoichi]], [[KamenRiderRyuki Shinji]], [[KamenRiderFaiz Takumi]], [[KamenRiderBlade Kazuma]], [[KamenRiderHibiki Hibiki]], [[KamenRiderKabuto Tendou]], [[{{Kamen Rider Den-O}} Ryotaro]] and [[KamenRiderKiva Wataru]].]]

Or, to explain further: the nine universes merging on top of Tsukasa and the Hikari family's home universe ARE the universes of ''[[KamenRiderKuuga Kuuga]]'' through ''[[KamenRiderKiva Kiva]]'', but they aren't the ones Tsukasa is visiting. Instead, he's being sent to AlternateUniverse versions of them to build up Decade's power. The real Heisei Riders are Stalling for time against the BigBad until Tsukasa becomes powerful enough to ensure their victory; this explains how they could somehow delay the merger (as the real Wataru says in the first episode) even though such abilities should have been beyond all of them.

How else can they get around Joe Odagiri's well-documented feelings of OldShame towards his time in ''KamenRider''?

[[WMG: Yuusuke has been replaced by a [[KamenRiderKabuto Worm]].]]

Why worse? In the second [[KamenRiderRyuki Ryuki]] World episode, Narutaki tells Decade that this world has been destroyed as well. Whenever Decade leaves a world, he destroys it.

[[WMG: Narutaki is an older [[KamenRiderDenO Yuuto Sakurai]]]]

* So did [[KamenRiderRyuki Shiro Kanzaki]].

[[WMG: The Shocker Orgnisation (of the original ''KamenRider'' series) is the real reason the nine worlds are merging]]

* Semi-confirmed InUniverse. [[spoiler:According to Kazuma (the original KamenRiderBlade), the worlds started merging when Decade was born. Apollo Geist accelerated it to allow Dai Shocker to gain power.]]

[[WMG: The [[KamenRiderKabuto red shoes system]] exists in Kabuto's world]]

(This is an easy premise for fanfic writers to abuse. If you want a KamenRider crossover, this is how to do it!)

* [[spoiler:In the scene at the end of the episode before the [[KamenRiderHibiki Hibiki]] World arc he does use a henshin device resembling Hibiki's, but we don't see him transform.]]

[[WMG: In the finale [[spoiler: the riders beating up Decade were not [[KamenRider Kamen Riders]] for real.]]]]
A KamenRider would never seek to kill another rider in order to save the multiverse, so [[spoiler: the Riders who beat up Decade in the finale weren't the real Wataru or Kazuma etc. They're clones made by [=DaiShocker=] to get Decade out of the way of their plans of destruction.]]

[[WMG: One of the "New worlds" (non-heisei worlds like Nega, [=DiEnd=] and [[SamuraiSentaiShinkenger Shinkenger]]) would be [[KamenRiderDragonKnight The World of Knight]]]]

[[WMG: The [[KamenRiderKuuga Kuuga]] World containing Yusuke Godai was the first to be destroyed by Decade's creation.]]

To reiterate: In ''TurtlesForever'', 2003 Shredder learns about the existence of the ''TeenageMutantNinjaTurtles'' multiverse and then attempts to erase all of it from reality. This has nothing to do with ''KamenRider'' at first glance, no?

[[WMG: KamenRiderBlack / [[KamenRiderBlackRX Black RX]] was the Showa Era Decade.]]

* Pretty much jossed as ''KamenRiderSpirits''' main villain Judo also known as the Great Leader can transform into the nine Showa Kamen Riders before Film/KamenRiderZX. Displaying also powers seen in Decade's Rider War prologue dream. Judo is the prototype of Decade. Decade is the Heisei era's Great Leader. Also if you believe in the ''JAKQ vs. Goranger'' movie, the original Kamen Riders, V3 and Amazon exist in the same world along with Kikaider.

[[WMG: Decade will end up destroying all the worlds, and in the process create the World of [[KamenRiderDouble Double]].]]

His appearence in the movies seem to counteract this, but considering how the last three series (Kabuto, Den-O, and Kiva) all featured time travel in some way, how he got there could be semi-reasonably justified. Rather, the fact that he just randomly appears, kicks Shadow Moon's ass, and leaves seem to indicate two things.

** Or perhaps not really; ''Movie War 2010'' reveals that Doctor Shinigami ''himself'' (and by proxy, his Ikadevil form) is really [[spoiler:a [[KamenRiderDouble Dopant]]. Yes, Natsumi's grandfather was somehow turned into a cosplaying junkie]].

She was [[KamenRiderDenO Den-o]] so the Trees had enough of an excuse to [[spoiler: do away with her.]]

[[WMG: Decade would have these cards for [[KamenRiderDouble W]] and [[KamenRiderOOO OOO]], if gained]]

[[BlueBeetle Jaime Reyes]] (a young man who was meant to be part of a conspiracy to take over the world uses his powers to turn into a bug like robot to fight the conspiracy) is the DC Rider. [[Comicbook/GhostRider Johnny Blaze and Danny Ketch]] (brother bikers who were given dark powers that allow them to transform into superpowered forms with which to fight evil) are the Marvel Riders. Since they are both B-List heroes in their own world, live in the US and don't speak Japanese they along with [[MaskedRider Drex]] and [[KamenRiderDragonKnight Kit Taylor]] never attracted the attention of the major players in the Dai-Shocker/Decade/Rider conflict.

Why yes, I did just claim that, in KamenRider's forty-year history and notorious track record with female Riders, the strongest Rider ever is a woman.

[[WMG: Decade is an [[MetalHeroes Uchuu Keiji]]]]

This didn't happen in All Riders vs. Daishocker because there was no one to trigger his transformation. That, and having a gigantic Decade wielding a gigantic Diendriver and assisted by all of the other riders would be the Rider equivalent of [[DivideByZero dividing by zero]].

[[WMG: Decade visiting the remaining Showa Rider worlds makes his hair resemble all the members of OneDirection.]]

** Supposedly, Narutaki claims that he can't stop his journey so long as Decade is still alive in ''Super Hero Taisen'' - that's because he ''is'' Decade.
