[[WMG: This movie will be epic]]
Well duh, but until it happens this is a guess.
* Pretty much jossed given [[http://www.jefusion.com/2012/04/super-hero-taisen-summary-spoilers.html the apparent trainwreck of a plot]].
** Which isn't actuall jossing. Something that sounds crap on paper can still be epic.
*** YMMV. Early reviews point out the plot as being especially problematic. Whether its epic or not depends on whether you care at all about plot or not.
*** The plot in these things is always secondary to the mere spectacle of the team up, in this case times a couple of hundred.

[[WMG: Kikaider, Kikaider 01, Inazuman, and Kaiketsu Zubat will appear in this movie]]
They appeared in the Kamen Rider 40th anniversary movie.
* Jossed.

[[WMG: Metal Heroes will appear in this movie]]
Gavan appeared in a Gokaiger movie.
* Jossed.
** The ''next'' Super Hero Taisen, however...

[[WMG: [[Series/SamuraiSentaiShinkenger Takeru]] will appear in this movie.]]
He's had history with Decade before, so it wouldn't come across as much of a surprise to see him, really.
* Jossed.
** Proof of this being Jossed?
*** Of course Takeru appears, he's a red ranger. Unfortunately, he only appears transformed as Shinken Red, and with a TheOtherDarrin voice.
*** OP here -- I meant unmorphed, so yeah. I'm sad now.

[[WMG: Why 240 heroes?]]
Excluding the extra Riders, there are only 27 Kamen Riders. If you ''do'' include the extra Riders, there are a lot more than 40 of them. So this spot on the WMG page is for the theories you can come up with on how Toei is even going to actually pull off 240 heroes.
* While there are definitely a lot more Kamen Riders than just 40, it's possible that those that were just in a movie/1-2 episodes/villain role were cut. 1-hit wonders and evil Rangers didn't make it into Super Sentai's 199, so neither will those equivalents of Kamen Rider make into their 40. I believe they're only going to count main Riders (currently 28, including Fourze), and main secondary Riders only (such as G3, Gatack, Diend, Meteor, Birth, etc.). I believe there's only 12 Secondary Riders, given that they became a tradition after Agito.
** Eh... there may be exceptions to that rule, like Odin possibly showing up alongside Ryuki and Knight, or Lengale and Challice, as well as Blade and Garren, showing up to help.
** Apparently there will only be 171 Sentai warriors in the movie (176 if we count the Dekaranger SWAT modes separately). With the exception of Big One, Gokai Silver and the green and black duos from Liveman and Go-onger, none of the extra rangers will be featured (not even ThreePlusTwo additions from ''Hurricaneger'', ''Abaranger'' and ''Gekiranger'').
*** The main page also states it's been said the Rider count is up from 40 to 50, for a total of 226 heroes. Not 240, but still definitely impressive.

[[WMG: The Gokaigers and Go-Busters will have no interaction with each other in this movie.]]
Cause they'll want to save that for the vs. special in January.
* Confirmed and jossed: the Gokaigers step save the Go-Busters from Decade early on in the movie. Though aside from standing alongside eachother during the gathering of heroes before the big battle, the Go-Busters telling Decade and Gokaigers that they will take care of the giant Warz and Akudos Gill, and the Gokaigers observing the Go-Busters from a distance at the end of the movie, they barely interacted at all.

[[WMG: After this movie there will be another ''Super Hero Taisen'', with Series/MetalHeroes joining Sentai and Kamen Rider.]]
There are roughly 50 Metal Heroes, add that to the 240, and take in a few of whatever new heroes are coming up in Sentai and Kamen Rider, and we could get Film/ThreeHundred.
* Seemingly Jossed: A sequel has been announced in the form of ''Super Hero Taisen Z'', which will pit Riders and Sentai against... forgotten non-Rider Creator/ShotaroIshinomori characters. Ishinomori played no part in the creation of the Metal Heroes...
* Unjossed. Confirmed with the [[http://www.jefusion.com/2012/12/gavan-typeg-joins-super-hero-taisen-z.html news]] that [[Film/SpaceSheriffGavanTheMovie Gavan TypeG]] is in it. Its full title would be [[http://www.jefusion.com/2013/01/kamen-rider-x-super-sentai-x-space-sheriff-super-hero-taisen-z.html "Kamen Rider x Super Sentai x Space Sheriffs: Super Hero Taisen Z"]].
* Semi Jossed. Not all Super Sentai, Kamen Riders and Metal Heroes showed up.

[[WMG: Both Captain Marvelous and Tsukasa Kadoya will be BrainwashedAndCrazy]]
They would probably be under the control of both Shine and The Great Leader.
* Or maybe under Doctor G. There is a scan shows a monster-version of him. Why else did he have such scan?
* [[spoiler:Jossed. They were pretending to be evil in order to simultaneously get the villain armies to reveal their schemes and draw them out into an unfavorable combat position.]]

[[WMG: Marvelous will use Basco's trumpet to try and take the greater power of the Kamen Riders.]]
* It's known that he is out looking for it, and it's doubtful that Marvelous in his [[BrainwashedAndCrazy current state]] will do the usual routine of them eventually giving it to him by choice.
* Jossed. There is no reference to Basco anywhere in the film.

[[WMG: There will be a ShoutOut TO Series/MightyMorphinPowerRangers and Series/MaskedRider.]]
* in the form of having Series/KyoryuSentaiZyuranger fighting [[Series/KamenRiderBlack Black]], [[Series/KamenRiderBlackRX RX]], [[Film/KamenRiderJ J]], and [[Film/KamenRiderZO ZO]] with a slightly TakeThat on how Series/MaskedRider used the suits.
** Jossed, but Super Hero Taihen did make a Power Rangers reference.

[[WMG: Marvelous will transform into [[Series/KousokuSentaiTurboranger Red Turbo]] and [[Series/DenjiSentaiMegaranger Mega Red]] during his battle with Fourze.]]
Just as how Tsukasa will transform into Riders who are similar to the Go-Busters while fighting them (Faiz and Kabuto's powers originate from a company like the Go-Busters, as well as Kabuto and Red Buster's SuperSpeed abilities), it would only make sense that Marvelous transform into Red Rangers who are similar to Fourze. Think about it: both the Turborangers and Megarangers were High School students during their respective tenures like Fourze is now. Next, all three heroes were not the brightest bulbs of their schools. Finally, Mega Red and Fourze both have a drill weapon (Kenta's Drill Saber and Gentaro's Drill Switch).
* Jossed. The previews reveal that Marvelous will use [[spoiler:Denzi Red and Magi Red]] against [[spoiler:Fourze's Elek and Fire States]] respectively.

[[WMG: The ones behind all this are Narutaki and Basco.]]
Narutaki still wants Decade out of the way, and Basco (brought back to life by the magic of crossovers) still wants a Great Treasure. If ''Gokaiger'' is anything to go by, using the Kamen Rider universe's Great Treasure will erase the Kamen Riders from existence. So the two cut a deal; Basco gets the Treasure, Narutaki gets to take over the KR universe after the Riders are dealt with. But in order to get those pesky Sentai out of the way, they engineered the LetsYouAndHimFight situation in the hopes that the Riders would take out the Rangers. Or, alternately, the Marvelous we've been seeing so far is Basco in disguise and the real Marvelous will return about halfway through the movie.
* Semi Confirmed, Narutaki was behind it but with Rider Hunter Silva, not Basco.

[[WMG: The Great Leader is behind it all and has taken possession of Decade and Gokai Red.]]
The Big Machine project was to trick the Heroes into fighting each other. While they were fighting, the two evil organizations were working on conquering the universe. They combined their battleships, Crisis Fortress and Gigant Horse, to create the Big Machine.

Big Machine in the original Kamen Rider manga is the name of Shocker's Great Leader.
* Jossed. Narutaki was behind it all.

[[WMG: Beet Buster and Stag Buster will make their EarlyBirdCameo here.]]
173 Sentai warriors have been confirmed for the movie. This excludes all of the sixth rangers and extra heroes outside of [[Series/KaizokuSentaiGokaiger Gokai Silver]], as well as some of the non-sixth extras such as the [[Series/NinpuuSentaiHurricaneger Gouraigers]], [[Series/BakuryuuSentaiAbaranger Abare Black & Killer]] and [[Series/JukenSentaiGekiranger Geki Violet & Chopper]]. This means there's one team with six members, five teams with three members (15, counting the initial ''Go-Busters'' roster) and thirty teams with five members (150). Since that only adds up to 171, that leaves two Sentai warriors unaccounted, which means that the extra members of the Go-Busters will make an appearance here, much like Gokai Silver did in ''199 Heroes''.
* Disconfirmed. The two unaccounted rangers are Geki Violet and Chopper, who appear in a flashback only.

[[WMG: Tsukasa is using Dai-Shocker, same as last time]]
Seriously, given what happened in that movie, do you think he'll be so quick to trust them again? They literally kicked him out in favour of his sister and Shadow Moon.
* [[spoiler:Confirmed]].

[[WMG: [[Franchise/MarvelCinematicUniverse Loki]] is behind everything.]]
You thought it was a coincidence that two big [[DuelingMovies superhero crossover movies]] came out so close together? Loki who has demonstrated the ability to revive the dead in the comics (being the Father of Hela has it's advantages) resurrected the villains of the various Sentai and Rider series to keep Japan's vast array of heroes busy while he invaded the rest of the world. Once he had the Tesseract and established a foothold in North America (who at the time had only a handful of unorganized heroes) he would have had more of a chance against the Japanese heroes. Besides doesn't pitting two factions of heroes into killing each other sound like something Loki would do?
* Nope. And thank god this didn't happen, because we don't need his insane fangirls ruining Kamen Rider and Super Sentai along with what he's already from.

[[WMG: The [[spoiler:destruction of the Riders in the Sentai World also caused the creation of the Metal Heroes and Anime/PrettyCure.]]]]
* Let's face it, all of that Rider-based awesome couldn't be held in with just a bunch of costumed heroes in spandex. Thus, the likes of SpaceSherrifGavan and [[Anime/FutariWaPrettyCure Cure Black and Cure White]] were created in order to fill in niches that the Sentai would have missed.
** Very funny. None of the Kamen Riders died in the Super Hero Taisen movies. Also, jossed to the max.

[[WMG: [[spoiler: [[Series/KamenRiderDenO Owner]] was in on Marvelous and Tsukasa's plan]]]]
* Only reason he allowed the others to return to the past.
** It would also explain how Decade was able to find the Timerangers.

[[WMG:Tsukasa and Marvelous pulled off their fake-kills using...]]
...the powers of known heroes that came back from the dead. [[Series/KamenRiderKuuga Kuuga Growing Form]] and [[Series/MahouSentaiMagiranger MagiMother.]]

[[WMG: [[spoiler: [[Series/HikoninSentaiAkibaranger Hatte Saburo]] is behind it all]]]]
You know he is.
* Jossed very hard. Narutaki is/was behind it all.

[[WMG:Diend is officially a villain now.]]
* [[spoiler:I really can't see Decade or the others letting him slide considering the whole Big Machine thing at the end.]].
** Really? He only killed two people with the Big Machine, and they were Warz and Akudos Gill. It's easier to forgive him than Marvelous and Tsukasa.
** Jossed although Diend is known to be a villain, anti-hero and hero, depending on the situation and he saluted to Joe and made peace with Tsukasa.

[[WMG:Super Hero Taisen Z will have a scene where [[Series/TokusouSentaiDekaranger DekaYellow]] and Skydain are fighting each other.]]
* For the sake of ActorAllusion. Much better if [[Series/TokusouSentaiDekaranger DekaYellow]] will be saving Nossan's sister from Skydain.
** Jossed.
