OOO, Den-O, All Riders: Let's Go Kamen Riders

is a Japanese superhero crossover film between Kamen Rider OOO, Kamen Rider Den-O, and the original Kamen Rider. The film serves to commemorate the 40th anniversary of the franchise, and marks the 60th anniversary of Toei Company, thus it features special appearances of characters from Shotaro Ishinomori's other works: Kikaider, Kikaider 01, Inazuman, and Zubat. In the film, Eiji joins forces with the DenLiner Crew to correct a time anomaly caused by Ankh in the 1970s.
The catchphrase for the movie is . 
==Continuity and Placement==
*Kamen Rider OOO: Judging from the date, April 1st, 2011, and Eiji not knowing Shocker, this movie is likely set between episodes 28 and 29. However, there are possible errors such as Eiji in the beginning of this movie is shown to have a full set of red, yellow, green, blue and gray medals.
*Kamen Rider: Scenes in the past take place on November 11, 1971, positioning it between episodes 32 and 33 of the original series. However, certain aspects of the film do not align with events from the original series. These inconsistencies include the presence of the upgraded Double Riders, Takeshi Hongo being active in Japan during that period, the sudden arrival of General Black, the absence of any mention of Geldam, and the sudden appearance of Kame Bazooka despite Destron not existing at that time.
==Story==
The film begins with Kamen Rider OOO battling three Mole Imagin, which retreat into the body of a boy. The DenLiner suddenly appears, and Kotaro Nogami and Teddy pinpoint the timeline where the Mole Imagin trio went. Eiji Hino and Ankh board the DenLiner on its way to November 11, 1971, but are instructed by the Owner not to exit the train while New Den-O deals with the rogue Imagin, as their presence may disrupt the flow of time. Upon arriving in 1971, New Den-O eliminates two of the Mole Imagin, with the third one still on the run. Wanting to take all of the Medals to himself while the other Greeed are still asleep in the timeline, Ankh sneaks out of the DenLiner, with Eiji chasing him before they bump into the third Mole Imagin. New Den-O destroys the Imagin, but the resulting explosion causes Ankh to drop a Cell Medal. While Eiji and Ankh are scolded by the DenLiner crew on their way back to their timeline, a Shocker soldier picks up the Cell Medal on the ground and hands it to General Black.
The DenLiner arrives on April 1, 2011 to drop off Eiji and Ankh. There, Ankh's OOO Medal Holder is stolen by a couple of young boys, who lead them to a slum area where the case is passed on to other children. The chase is disrupted by the police, who reveal themselves as Shocker Combatmen. After escaping from the police, Ankh reveals to Eiji that Shocker took over Japan in 1971 before increasing their power over the years and conquering most of the world. Furthermore, Shocker has been inducted into the United Nations. Shocker has grown to incorporate other evil organizations from past Kamen Rider series such as G.O.D., Gedon, Gorgom and Crisis Empire. When one of the street children is caught by the Shocker police, Eiji changes into Kamen Rider OOO to battle them. As things get rather grim for OOO, help seemingly comes from the sudden appearance of Kamen Riders 1 and 2. But suddenly, as OOO was expecting help from his seniors, Riders 1 and 2 attack and weaken OOO. Seeing that he saved them, the boys then give OOO back the Medal case. OOO changes into Latorartar Combo to retreat and rush the children to safety, but is later on ambushed by General Shadow. The DenLiner, however, arrives to pick up Eiji and the children before they are captured.
Aboard the DenLiner, Teddy explains to Eiji that in 1971, Shocker got a hold of a Core Medal and modified it for their use, but found no results from it. But when a soldier picked up the Cell Medal that Ankh dropped, the Shocker Medal merged with it to form the Shocker Greeed, which swiftly defeated the Double Riders and made them Shocker's elite. Because of Shocker's change of power, Kamen Riders after the Double Riders ceased to exist. It is now the DenLiner crew's mission to travel back to 1971 and correct the timeline. Eiji and Shigeru - one of the children - are dropped back into the slum area, where Eiji meets Hina - who does not know him due to the timeline change. They also discover that Naoki and Mitsuru have stayed aboard the DenLiner. Ankh has also gone aboard to retrieve the Medal he lost, but is chained by the Owner, who has Momotaros keep an eye on him. The crew arrive one minute before their previous arrival and Kotaro recovers the lost Medal, but Ankh starts a fight aboard the DenLiner to get it back. This causes him to accidentally lose four Medals out the window; because of this, the crew are forced to jump off the train and handle the situation. Three of the Medals are destroyed, but the fourth is picked up by a girl named Nokko, who mistakes the crew as Shocker henchmen and alerts the Kamen Rider Scouts of their presence. Throughout the whole ruckus, the Medal is once again picked up by a Shocker Combatman and handed over to General Black. Kotaro changes into New Den-O Strike Form while he and Momotaros battle the Shocker platoon, with General Black changing into Hilchameleon. Naoki, Mitsuru and Nokko recover the Medal and escape into a warehouse, but are surrounded by Shocker Combatmen before the Double Riders appear and intervene - destroying the army's two Kaijin commanders with their Rider Kicks. The Double Riders and the children trick Hilchameleon into taking a fake Medal with a transmitter so they can locate Shocker's headquarters. Before they proceed, New Den-O destroys the real Cell Medal to prevent any further trouble.
The DenLiner arrives at the Shocker headquarter's location, where the Double Riders, New Den-O and Momotaros discover that General Black dropped a fake Medal during the earlier fight and that Shocker has the real Cell Medal intact, while at the same time, they lured the Riders into a trap. The Great Leader then awakens Shocker Greeed while General Black calls out Ika Devil, Garagaranda and other revived Kaijin before changing into Hirucameleon and battling the Riders. While New Den-O and Momotaros are having difficulty fighting Shocker Greeed, the Double Riders dispose of the revived Kaijin and unmask the Great Leader. Outside, Kame Bazooka fires at the DenLiner and seriously cripples it, forcing the Owner to order a retreat. The Double Riders tell Kotaro, Momotaros and the boys to jump onboard while they handle Shocker Greeed. Still wanting to help the Double Riders, Naoki jumps off the DenLiner with Teddy following him before it heads back in time.
On April 2, 2011, Shocker initiates a mass extermination of the remaining human race. As OOO continues to protect the slum area from the invading Shocker army, the damaged DenLiner returns. Kotaro, Momotaros, Ankh and Mitsuru jump off before the DenLiner explodes. Losing his OOO Driver in the explosion, Eiji realizes that the DenLiner crew have failed in their mission and that the DenLiner's destruction means that the event cannot be undone. As Eiji and Kotaro are captured, Hina, Momotaros (reduced into a floating left arm), Ankh and the children make their escape. On their way to safety, they discover a time capsule containing Kamen Rider Scout uniforms and a letter from Naoki, telling them that after Shocker Greeed defeated the Double Riders, he and the Scouts became fugitives while Teddy died while protecting them. Surrounded by Shocker Combatmen, Momotaros takes over Ankh's body and uses Teddy's dead Macheteddy form to keep the enemy busy while Hina and the children run off with the OOO Driver.
Many humans are gathered at a plaza to bear witness to the crucified Eiji, Kotaro and Ankh as they are about to be executed by a firing squad. The children - now dressed as Kamen Rider Scouts - make an attempt to deliver the OOO Driver back to Eiji but are quickly apprehended before the Double Riders appear, revealing that the guilt-stricken scientists did not brainwash them while they pretended to serve Shocker until the time came to show their true colors. The human audience scrambles to revolt against Shocker and unchain Eiji, Kotaro and Ankh. Eiji changes into OOO, while Kotaro has Momotaros take over his body before changing into New Den-O - armed with the Momotaken. Just as the four Riders are outnumbered, the playing field is changed with the sudden appearance of all of the Kamen Riders. The Owner appears out of the crowd, explaining that Riders will continue to exist as long as justice prevails. The DenLiner reappears and runs over General Black before Teddy is reunited with New Den-O while Momotaros and the other Imagin change into Den-O Climax Form. General Shadow attempts to escape the Riders, but Owner reminds him that the Kamen Riders aren't the only protectors of justice here. Kikaider, Kikaider 01, Inazuman and Zubat then arrive and use their respective finishers to take out General Shadow before taking their leave. The Double Riders have a rematch with Shocker Greeed while the other Riders rush toward Great Leader. Shocker Greeed is destroyed by the Rider Double Kick before Ankh takes the Shocker Medal.
When the Riders are overpowered by Great Leader's attacks, Ankh convinces OOO to use the Shocker Medal and an Imagin Medal that Ankh created from Momotaros in combination with the Taka Medal. With the three Medals, OOO changes into Tamashiy Combo and destroys Great Leader with the Tamashiy Bomber. The attack, however, unleashes Great Leader Colossus - the true form of Great Leader, who throws fireballs at the Riders and consumes the other Shocker leaders in an earthquake. The Riders are joined by Kamen Rider Birth and all of the other secondary Riders to battle the new menace. All of the Riders jump into their motorcycles to execute the All Rider Break, destroying Great Leader Colossus and permanently ending yet another Shocker threat to Earth.
In the end, a middle-aged man in a white coat appears before Eiji, Kotaro, Momotaros, Teddy, Hina and the Scouts. He is revealed to be not only Naoki, but Mitsuru's father. He reveals that he married Nokko and became a Shocker scientist to prevent the brainwashing of the Double Riders. As the Imagin and Shocker medals dissolve, much to Ankh's dismay, the heroes bid each other farewell before the DenLiner embarks on its next destination.

== Theme song ==
*"Let's Go Rider Kick 2011"
** Artist: Kamen Rider Girls
The title "Let's Go Rider Kick 2011" is an homage to the original theme song of the Kamen Rider television series "Let's Go!! Rider Kick". The single was released on April 20, 2011.
==Core Medals==
*Medals Used:
**Head - Taka, Lion
**Arms - Tora, Kujaku, Imagin
**Legs - Batta, Cheetah, Condor, Shocker
*Combos Used:
**Tatoba Combo, Latorartar Combo, Tajadol Combo, Tamashiy Combo
==Errors==
*General Shadow appears representing the Delzer Army, but is not seen wearing the cape he wore while leading the Delzer Army in Kamen Rider Stronger following his stint as an executive of Black Satan.
*Despite all Imagins turning into sand upon death, Teddy's physical body remained in weapon form after being murdered by Shocker's forces.
*How Momotaros managed to stay alive as an arm upon the Den-Liner's explosion was never properly explained, given that Imagin's typically do not have such abilities. Furthermore, it also left unexplained why he had the Imagin Core Medal inside of him.
*Strangely, the four Taros somehow assumed Climax Form without Ryotaro as their host, which was previously established as an impossible task. 
*Although most of the Riders that assisted Kamen Riders 1, 2, New Den-O and OOO were good, some of them were outright villainous Riders.
**Given the severity of the situation though, it is understandable why they joined forces against the Great leader of Shocker.
**Alternatively, a different individual was using the powers of said villainous Riders, hence their cooperation.
*Kamen Rider Double should not be able to meet Eiji Hino, considering how Phillip's full restoration happens on the penultimate episode of Kamen Rider OOO.
*Considering the existence of Metalgelas and Volcancer as a part of Shocker army, it is unknown how Kamen Rider Gai and Kamen Rider Scissors was recruited in the first place as they are their contract monsters.
*It is unknown how Hajime Aikawa/Kamen Rider Chalice could have assisted Kazuma Kenzaki/Kamen Rider Blade in this film, considering how they are currently forced by the Monolith to oppose each other as the Joker Undeads. 
**With the alteration of history, it is possible that Kazuma's mutation was reversed in the process, hence why he and Hajime can cooperate with each other as allies.
**This seems likely when considering the several Undeads' alignment of Shocker, likely meaning that Kazuma never had to forsake his humanity in this timeline.
==Release==
*The film was originally scheduled to release on March 15, 2011, but was postponed due to the that occurred on March 11. It was later released on April 1, 2011.
==Reception==
Let's Go Kamen Riders opened at the #1 spot in the Japanese box offices in the first two weekends.
==Notes==
*The film's subtitle "Let's Go Kamen Riders" is an homage to the theme song of the original series, .
*This is the first time in nearly 30 years where Kamen Riders 1, 2, and V3's original actors are seen reprising their roles, though without appearing in their civilian forms.
*This movie currently holds the record for most Riders featured in one film, with almost every single Rider appearing, save for several Movie Exclusive and/or Villainous Riders.
*This is last Kamen Rider film to premiere in Spring before series takes its place.
**It would be the first Spring Movie that feature Net Movies as it would continue on in Super Hero Taisen series.
*The translucent section of Blade's helmet in this movie appears to have been discolored, possibly due to aging. This is also prevalant in his subsequent appearances such as Kamen Sentai Gorider, Kamen Rider Heisei Generations Forever and Blade Joker!? 2019.
*When the Riders were about to form the All Rider Break, they formed the number 40 because it was the 40th anniversary of the franchise. It's formation began when 1 told the Great Leader that all of the Riders would pass on the struggle of their 40 year battle.
