Film: Kamen Rider X Super Sentai Super Hero Taisen aka: Superhero Wars Kamen Rider Vs Super Sentai
When all hell's breaking loose, you'll be right in the eye of the storm.
Kamen Rider × Super Sentai: Super Hero Taisen is an upcoming film (release date April 21) that will pit Toei's two most prominent Toku franchises against one another in a giant Cross Over battle. What is known of the plot so far: Captain Marvelous, AKA Gokai Red, has formed Dai-Zangyack and attacks the Kamen Rider universe, hoping to claim their Grand Powers and the Ultimate Treasure in the Universe. Opposing them is Dai-Shocker, reformed by Doctor G and again lead by Tsukasa Kadoya AKA Kamen Rider Decade. Meanwhile, Rangers and Riders on both sides of the conflict are left wondering what's going on and why they're even fighting to begin with.Oh, and it'll feature nearly 300 Rangers, Riders and villains fighting alongside one another. And the Fandom Rejoiced.Confirmed to return so far:
The Cameo: It's been confirmed that Ryosuke Sakamoto, Yudai Chiba, Asaya Kimijima and Hiroaki Iwanaga will provide voiceovers for their characters (Red One, Gosei Red, Kamen Rider Birth and Birth Prototype respectively), but will not be appearing out of costume.
Colour-Coded for Your Convenience: The Gokaigers will change into their respective colors or the closest match when using OOO's combos. Which means that, for better or worse, Gai gets the gray SaGoZo basic form, while the purple PuToTyra Super Mode goes to Ahim.
Demoted To Dragon: Major villains playing second fiddle to a Rider and a Sentai warrior? The real mystery here is who is going to be the true Big Bad once Decade and Gokai Red get double-crossed.
MacGuffin: Apparently Marvelous is after the Best Treasure in the Kamen Rider Universe, and needs the Greater Powers of the Kamen Riders to acquire it.
Meaningful Rename: Bio Hunter Silva becomes "Rider Hunter Silva" due to his new role as an enemy of the Riders.
Mind Screw: The film's very premise, out of andIn-Universe. Nobody except Tsukasa and Marvelous seems to know why they're fighting. This causes Kaitou, Hina, Joe and Don to join forces and try to figure out what's going on.
Mythology Gag: Marvelous transforming into Shinken Red during his fight with Tsukasa references the previous Sentai/Rider team-up.
We also have Decade changing into Rider #1, his first-ever Showa change.
And some participants will copy each other's powers: Gokaigers with OOO keys, Go-Buster-Oh with Fourze and his Switches, and the various card-based Riders with Gosei cards.
Pun-Based Title: The tie-in net movies are mystery stories, with the title Super Hero Taihen.
According to some summaries, Shocker has also inducted some Riders into their ranks, although this was on the pretense of fighting against Dai-Zangyack.
We Have Reserves: Tsukasa delivers a speech to his minions saying (paraphrased): "Your only strength is that you keep coming back no matter how often you're killed, so go out there fully expecting to die and don't give up until all the Rangers are defeated!"
"With Our Swords" Scene: Heroes from each side lend the other their powers: OOO loans the Gokaigers his Core Medals, which turn into Ranger Keys for his six single colored Combo forms, while the Goseigers loan Decade, Blade, and Ryuki their Attack Reflector cards in order to battle Kani Laser.
