Spoilers for all preceding Toei tokusatsu entries up to Kamen Rider Heisei Generations: Dr. Pac-Man vs. Ex-Aid & Ghost with Legendary Riders and Doubutsu Sentai Zyuohger will be left unmarked. You Have Been Warned!
Kamen Rider x Super Sentai: Chou Super Hero Taisen (released on March 25, 2017) is a crossover film between Toei's two most prominent Toku franchises, the fifth and final in the Super Hero Taisen series of films.
The Game World launches an attack on the Real World. In front of Kamen Rider Ex-Aid and Uchu Sentai Kyuranger appears the "Arena of Death" where the destruction of the Earth will be decided. Trapped in this inescapable dimension, generations of Super Sentai and Kamen Riders must engage in a Battle Royale. An unprecented battlefield of many puzzles connecting the Real and Game worlds. And then, "Those Heroes" revive... Everything is scaled up, all rules are broken! And when it seems like the real world will fall into a disaster, imagination brings forth unimaginable New Heroes!
Tying to this movie is Kamen Rider Ex Aid Kamen Sentai Gorider, three web episodes starring Emu and past dead riders trying to escape an amusement park.
This movie provides examples of:
- A Day in the Limelight: Amu and Naga get the most focus of the main Super Sentai teams featured. Amu is in fact the only Zyuohger that appears out of costume. Hiiro of Ex-Aid also gets a large amount of focus.
- Action Girl: Reflected in Chou Super Hero Taisen's Team Women.
- Actor Allusion: When Yakumo (AoNinger) joins Emu's team, he suggests recruiting Tsubasa Ozu (MagiYellow), who was established as his mentor by a Continuity Cameo in Ninninger #38, only to be joined by the identical Masato Jin (Beet Buster), who was also played by Hiroya Matsumoto. Furthermore, the gold-colored Beet Buster fills the slot to become the yellow Ki-Rider.
- Alternate Universe: The Game World of Chou Super Hero Taisen.
- Alternate Self: Of the starring heroes, only Ex-Aid (plus Brave & Snipe), the Kyurangers and the Zyuohgers are the real deal. All other heroes (and all the villains), that's including Lazer and Genm, come from the Game World.
- Back from the Dead:
- Kamen Rider Lazer returns in this movie, the Ex-Aid cast obviously shocked by his revival, though he appeared temporally to fight against Xevious, together with random previous long-ranged heroes.
- Reflected in Chou Super Hero Taisen's Team Resurrection, whose members were previously revived or otherwise revealed to have escaped their apparent deaths.
- The premise of the spin off Kamen Sentai Gorider is, other than Ex-aid, the other five Riders being dead. The fact that Kenzaki is among them despite just being turned Undead, and why he shouldn't be dead, show he isn't actually him.
- Behemoth Battle: Oogumo Great Leader, piloting a red-colored Big Moraimarz Robo courtesy of Jark Matter, is taken down by a combination of the following: Kamen Rider Ex-Aid Maximum Gamer Level 99 (enlarged by an Energy Item), and two versions of KyurenOh created when Shishi Red uses the Futago Kyutama to duplicate his Shishi Voyager, allowing the limb Voyagers of his eight teammates to be used all at once.
- Better than a Bare Bulb: Momotaros' appearance during the "character select" sequence lampshades the fact that he's counted as a Pink character by having Emu remark "But you're red" and Momo replying that it's pretty much entirely because of his namenote .
- Big Bad: The Game World's Shocker is led by Shocker Leader III.
- Canon Welding: Coming from the Game World are counterparts for Amazons Riders Alpha, Omega and Neo, with a Bat Amazon and Neo Deboth among the Legion of Doom. This movie thus cements the standalone Amazons as part of the Rider multiverse and Dino Force (Kyoryuger) Brave in Super Sentai continuity, preceeding the appearance of the Zyuohgers in their finale.
- Darker and Edgier: Moreso than its predecessor. Doesn't help that the recent entries are already dark in their own right. Also, just like Ex-Aid and Amazons, the movie runs on Grey-and-Grey Morality.
- Defeat Equals Explosion: Exaggerated as this fate befalls all the movie's defeated villains.
- Degraded Boss: Kamen Rider Genm Zombie Gamer Level X is bested by Kamen Rider Ex-Aid Robot Action Gamer Level 3 despite greatly outclassing him.
- Early-Bird Cameo: This movie features the first appearance of Kamen Rider Amazon Neo before his introduction in the second season of Kamen Rider Amazons.
- Raimein from Power Rangers Dino Force Brave appears as part of the Legion of Doom before the premiere of his series.
- End of an Age: This film serves as the final Super Hero Taisen installment to date. According to Shinichiro Shirakura in a press release tweet for Kamen Rider Heisei Generations FINAL: Build & Ex-Aid with Legend Riders that the Taisen series would end to pursue more "interesting" projects, that is Kamen Rider Amazons: The Last Judgement.
- Evil Counterpart: In the Game World, Ex-Aid is pitted against a trio of Dark Riders, the counterparts of Kabuto, Drive and Ghost.
- Final Battle: The Gamer Riders, the Kyurangers and the Zyuohgers, along with Riders and Sentai summoned from the Chou Super Hero Taisen world, against Shocker Leader III's army.
- Groin Attack: Momorenger delivers one to Momotaros after pretending to cower before his overpowering might, netting her a point for her team.
- Hijacked by Ganon: The Game World's attack ultimately turns out to be from yet another incarnation of Shocker.
- In the Name of the Moon: For the Goriders.Emu: "Aka-Rider!"Yakumo: "Ao-Rider!"Jin: "Ki-Rider!"Kitaoka: "Mido-Rider!"Momotaros: "Momo-Rider!"All: "Kamen Sentai... Gorider!"
- Lady Not-Appearing-in-This-Game: A promotional conference for the film presented a mixed team of heroes as an example of thoe which would appear. Known as Team Legend Hero, this team was composed of Kamen Rider Kuuga, Kamen Rider Meteor Storm, Kamen Rider Ryuki, DragonRanger and NinjaBlack, but they did not actually appear in the movie themselves.
- Legion of Doom: Shocker, from the Game World, with an army of monsters from across the histories of both Kamen Rider and Super Sentai.
- Let's You and Him Fight: As usual for the Super Hero Taisen movies. Unlike previous examples, however, which have usually had simple "Rider vs Sentai" or "Rider vs Rider" fights, this one is a complete free-for-all - they've shown Sentai teams fighting one another!
- Long-Range Fighter: Heroes that specializes in long-ranged weapons are summoned through the Chou Super Hero Taisen game to combat Xevious.
- Make My Monster Grow: A heroic example: Ex-Aid (Maximum Gamer Level 99) uses an Energy Item provided by Hiiro to enlarge himself to the level of a Super Sentai Humongous Mecha.
- Massive Multiplayer Crisis Crossover
- Mooks: As well as Shocker Combatmen, there are Buglars, Zorima, Kuros and Moebas.
- Mythology Gag: Oogumo Great Leader is a humanoid spider, matching the very first Monster of the Week from the original series. He also sports the Double Riders' "insect wings" design on his back.
- Ninja: Reflected in Chou Super Hero Taisen's Team Ninja.
- Offscreen Moment of Awesome: Within the Game World, a weakened Ex-Aid Double Action Gamer Level X is confronted by three Dark Riders. He ends up overcoming them off-screen.
- One-Winged Angel: Shocker Leader III is the spider-themed monster, Oogumo Great Leader.
- Original Generation: Kamen Rider True Brave and Kamen Sentai Gorider.
- Ninja Pirate Zombie Robot: The movie not only includes Kamen Riders and Super Sentai teams, but a Sentai Team composed of Kamen Riders: Kamen Sentai Gorider.
- The Smurfette Principle: Inverted. Oren is the only male on the aptly-named "Team Women". Fans of Gaim know why.
- Super Mode: During the Final Battle, a team of Rangers and a team of Riders using these is summoned to help the heroes. The former includes Red Buster Powered Custom, Kyoryu Red Carnival, Hyper Toq-1gou, and Akaninger Chouzetsu while the latter has Kamen Rider Agito Burning Form, Kamen Rider Ryuki Survive, Kamen Rider Decade Complete Form, Kamen Rider Drive Type Tridoron, and Kamen Rider Ghost Mugen Damashii.
