This movie will be epicWell duh, but until it happens this is a guess.
Kikaider, Kikaider 01, Inazuman, and Kaiketsu Zubat will appear in this movieThey appeared in the Kamen Rider 40th anniversary movie.
Metal Heroes will appear in this movieGavan appeared in a Gokaiger movie.
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.
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.
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.
After this movie there will be another Super Hero Taisen, with Metal Heroes 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 300.
Both Captain Marvelous and Tsukasa Kadoya will be Brainwashed and CrazyThey would probably be under the control of both Shine and The Great Leader.
Marvelous will use Basco's trumpet to try and take the greater power of the Kamen Riders.
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 Let's You and Him Fight 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.
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 is the original Kamen Rider manga is the name of Shocker's Great Leader.
Beet Buster and Stag Buster will make their Early-Bird Cameo here.173 Sentai warriors have been confirmed for the movie. This excludes all of the sixth rangers and extra heroes outside of Gokai Silver, as well as some of the non-sixth extras such as the Gouraigers, Abare Black & Killer and 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.
Tsukasa is using Dai-Shocker, same as last timeSeriously, 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.
Loki is behind everything.You thought it was a coincidence that two big 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?
The destruction of the Riders in the Sentai World also caused the creation of the Metal Heroes and Pretty Cure.
Owner was in on Marvelous and Tsukasa's plan
Tsukasa and Marvelous pulled off their fake-kills using......the powers of known heroes that came back from the dead. Kuuga Growing Form and MagiMother.
Hatte Saburo is behind it allYou know he is.
Diend is officially a villain now.
Super Hero Taisen Z will have a scene where DekaYellow and Skydain are fighting each other.
