The catchphrase for this movie is "Get up, all superheroes! All of space versus all of Earth: the one and only ultimate battle begins!" (立ち上がれ、全スーパーヒーローよ！！全宇宙対全地球 二度とない究極バトル開始！！,Tachiagare, zen sūpāhīrō yo! ! Zen uchū tai zen chikyū Nidoto nai kyūkyoku batoru kaishi! !)
A new evil organization known as Space Shocker (スペースショッカー,Supēsu Shokkā), which are led by the magic-using Space Ikadevil (スペースイカデビル,Supēsu Ikadebiru) and Space Spider Man (スペース蜘蛛男,Supēsu Kumo Otoko), threatens the Earth by causing an unknown phenomenon. The Space Sheriffs Gavan type-G and Sharivan are sent to execute all magic-users on Earth in response to the threat and begins to attack Kamen Riders Wizard and Beast. The Space Crime Syndicate Madou, who were once defeated by the original Sharivan return, to cause even more havoc in the world. During this, Yoko finds a mysterious little robot called Psycholon (サイコロン,Saikoron), which Space Shocker and the Madou are after for unknown reasons.
Magic gates appear throughout Japan, causing havoc as people are instantly transported from one place to another. While investigating the situation, Haruto Soma and Koyomi are approached by Geki Jumonji, who suddenly attacks Haruto after confirming his identity. Geki and Haruto fight as Space Sheriff Gavan type-G and Kamen Rider Wizard until Kamen Rider Wizard and Koyomi risk themselves to save a passerby from being hit by collateral damage. After confirming that both are good people, he stays his blade and flees. Meanwhile, Yoko Usami from the Go-Busters and her BuddyloidUsada Lettuce are camping beside a river until an unknown object falls from the sky beside them. They find a small robot at the crash site, which Yoko takes to the Energy Management Center and fixes it up. The robot introduces itself as Psycholon and she becomes friends with it.
Meanwhile at the Galactic Union, Geki confronts his superior and the previous Gavan, Retsu Ichimonji, about his orders to eliminate both Kamen Rider Wizard and Kamen Rider Beast, Kosuke Nitoh, but Retsu insists that both are too dangerous to be allowed to live because of their magical powers. Retsu relieves him from duty, sending the Space Sheriff Sharivan to complete the task. Back at the location where Yoko found Psycholon, monsters from the evil organization Space Shocker are confronted by Kamen Rider Wizard until they send him away using a magic gate. Haruto emerges at a stadium where he is encountered by the Kyoryugers who mistake him for a Debo Monster at, then challanged by Kyoruger's Daigo Kiryu to ddetermine how brave Haruto is until Gai Ikari from the Gokaigers appears to stop their fight as he wants to meet with Haruto about the incident of Space Shocker's plan of framing Haruto using a same magic power. Geki attempts to stop Sharivan from leaving to Earth to execute Kamen Rider Wizard and Kamen Rider Beast with no success. Yoko is attacked by Space Shocker, who are after Psycholon, but her fellow Go-Busters Hiromu Sakurada and Ryuji Iwasaki appear to assist her. When the monsters try to send both Yoko and Psycholon through a portal, Hiromu and Ryuji appear to save her and are sucked in instead, and she is forced to keep fighting by herself.
Gai and Haruto discuss the situation, later joined by Geki and Nito, until Sharivan appears to fight them. To dissuade his fellow Space Sheriff, Geki tries to don his combat suit with no success and his partner Shelly informs him that after he was removed from duty, the Dolgiran's systems were locked down, preventing her from providing him his weaponry. When monsters from Space Shocker also appear at the scene, Sharivan is forced to stop pursuing the other heroes to fight them until they flee through a portal leading to the Genmu World and Geki also dives there by himself to investigate. Past the portal at the Genmu Castle, Geki witnessess Strategist Raider from the Space Crime Syndicate Madou and Shadow Moon discussing their plan to use Psycholon to gather enough magic energy to revive Madou's leader Demon King Psycho, learning that they are the ones behind Space Shocker. Soon after, Gai appears to help Geki escape, and back on Earth, they rescue Yoko and Psycholon from Space Shocker troops. Taking refuge at the Antique Shop Omokagedō with the others, Geki reveals that the Galactic Union intends to destroy Earth with the Super Dimensional Cannon to prevent Space Shocker from completing their plan, as their scheme threatens the entire universe.
Encouraged by Gai and the others to not give up yet, Geki leaves to confront Space Shocker by himself until as Kai/Sharivan appears to that the evidence of the villains who framed Wizard and Beast of using a same magic power has been informed as the villains is on the moves to revived Madou and inform him that they have one hour until the Galactic Union fires their main weapon to destroy the Earth, then leaves to call Shaider for reinforcement. While Gai seeks help, Geki enters the portal to the Genmu World, accompanied by Yoko, Psycholon, and Nito, and they are attacked by Space Shocker. Separated from the others, Geki is forced to confront the monsters unarmed until Kotoha Hanaori from the Shinkengers appears at the Dolgiran, revealing that she was sent there by Gai. She hacks the ship's systems to lift the lockdown and allow Geki to transform into Gavan type-G once more. Yoko keeps pushing forward by herself until Reider and Shadow Moon appear to block her path and attempt to take Psycholon from her, and the little robot uses its powers to have her reunited with Hiromu and Ryuji. Just as Kamen Rider Beast and Gavan type-G are about to be defeated, several Kamen Riders and Super Sentai warriors, including another hero's Sangiman/new Inazuman appear to help them. Gai rejoins his fellow Gokaigers and Gavan type-G provides them with six Metal Hero Keys to assist in the fight.
The Go-Busters have a tough battle against Shadow Moon until the Gokaigers, Gavan, Kamen Rider Beast, Kamen Rider Wizard, Sharivan, Kamen Rider Fourze, and Kamen Rider Meteor appear to assist them, joined by Shaider, Kamen Rider OOO and the Kyoryugers also join the fight as well. As Shadow Moon and his reinforcements are defeated, the one-hour delay provided by the Galactic Union runs out and a regretful Retsu is forced to fire the Super Dimensional Cannon. The three Space Sheriffs then ride their ships and manage to stop the weapon's blast from hitting the Earth but Reider reveals that it was their intention all along to use its energy to complete the Demon King's resurrection. The resultant explosion provides enough power for it, before Reider perishes, just to later return as Space Reider, bringing several other monsters to the fight. Psycholon is also overcome by the energy surge and is put under Madou's control as well. The heroes find themselves in a pinch against their enemies until Akaranger and Kamen Rider 1 arrive with reinforcements. Kyoryu Gold appears to assist Kamen Rider Beast against Space Reider and together, they destroy him for good. Yoko calls out for Psycholon and it manages to break free from Psycho's control but ends up sacrificing itself to protect her from a fatal blast. The enlarged Psycho tries to escape into space, but Gavan type-G, Sharivan, and Shaider, who revealed to be alive appear to stop it, and the monster is ultimately destroyed by a robot formed by the Kyorugers' Kyoryuzin and Kamen Rider Wizard's WizarDragon combined. After the battle, Usada reveals to Yoko that Psycholon can be fixed, and as the Space Sheriffs return to space, the Kamen Riders and Super Sentai warriors bid their farewells after they had joined forces to protect Earth once more.
To promote the movie, Toei released a series of Internet clips under the collective title Kamen Rider × Super Sentai × Space Sheriff: Super Hero Taisen Otsu: Heroo! Answers (ネット版 仮面ライダー× スーパー戦隊×宇宙刑事 スーパーヒーロー大戦乙(おつ) ～Heroo!知恵袋～,Nettoban Kamen Raidā × Sūpā Sentai × Uchū Keiji: Supā Hīrō Taisen Otsu ~Hīrō! Chiebukuro~). The net movies also featured characters from Tsuburaya Productions and Marvel Comics. Toei Tokusatsu BB and TV Asahi began distribution on April 12, 2013.
Unlike the previous Super Hero Taisen, this film does not feature all Riders and Sentai Teams.
Despite Wajima appearing in this movie, he does not have any lines throughout the film.
There is some similarities between this film and the previous one:
The plot of the film focuses on previous heroes instead of current heroes (Wizard and Kyoryuger).
Both films have Shocker involved, but the villains (Phantoms and Deboth) that fight the current heroes (Wizard and Kyoryuger) don't appear. However, they are mentioned by Wizard and the Kyoryugers.
The current (Kyoryuger) and the previous Sentai (Go-Busters) appear in this film, but they don't really interact with each other, which is similar to the previous film (Go-Busters and Gokaiger).
Gai is the only sixth hero to be in both films (also the only Gokaiger to appear untransformed in this movie), while Kyoryu Gold only appears transformed in this film.
Usada is the only Buddy Roid to appear in both films, as J only appears for a brief moment in this film, but doesn't transform. Nick and Gorisaki appeared with Usada as the control interface of their respective Buster Machiens in Go-BusterOh in the previous film, with Nick also appearing in his bike form, but they didn't speak.
For the climax, the heroes that are present before reinforcements appear are the Kamen Riders and Super Sentai teams based on their Super Hero Time years:
OOO & Gokaiger (2011)
Fourze & Go-Busters (2012)
Wizard & Kyoryuger (2013)
The current Kamen Rider and Super Sentai heroes only appear transformed during the credits, while previous heroes appear in their civilian forms.
However, unlike the previous film, the previous Kamen Rider series (Fourze) only appears transformed in this film.
For the team Gokai Change in this movie, after the Gokaigers change into Metal Heroes, they use the Gokai Galleon Buster, similar to the previous film where they use the Gokai Galleon Buster after changing into OOO Combos.
Wizard and the Kyoryugers appear in their civilian forms at the beginning and later transform in the climax, similar to Fourze and the Go-Busters in Super Hero Taisen.
However, the Kyoryuger team actually appears to transform before the climax starts.
Also, the mecha battle has the current heroes (Wizard and Kyoryuger) fighting the monster.
Yoko gets ejected from RH-03 by the final enemy, similar to how she was ejected from Go-Buster Oh in the previous film.
Some characters only appear for a brief moment:
Kotoha Hanaori appears on Dol to help Shelly. (This is done as an inside joke to both characters being portrayed by the same actress, Suzuka Morita)
Saburo Kazeta appears transformed as Sanagiman to save Fourze from Space Spider Man before transforming into Inazuman to finish him off alongside Fourze. It is unknown how he got to the past in the first place.
Beet J. Stag appears sweeping after Beast and Kyoryu Gold finish off Space Reider.
Go-Busters vs. Gokaiger and the Go-Busters' two-part crossover with Gavan in their own series is acknowledged when Yoko bumps into Gai and Geki, needing no introduction, and the later crossover again when Hiromu is reunited with Geki.
Right after the closing credits, Kikaider makes a brief appearance, saying that these are not the only heroes on Earth. This may possibly signify a future major crossover like this featuring more heroes.
This movie reveals that at some point, Gai chose to stay on Earth while the rest of the Gokaigers left for space again.
This is the first Spring movie to not have Den-O to be the main character or even the supporting character like the previous Super Hero Taisen film.
This is the only Super Hero Taisen film to feature Metal Heroes.
