==Plot==
The film opens with Zawame City ravaged by a fight between the Heisei Riders and the Shōwa Riders, before going back in time to the week before, when workers from the Yggdrasill Corporation are dragged by an unknown force underground. Upon hearing rumors about it, Kouta Kazuraba investigates the area with Mai Takatsukasa, only to fall into a hole as well and find themselves in an underground, alternate version of the city. The two find a boy called Shu, who has the power to manipulate things, but does not remember what he is needed for. Kouta and Mai then bring the boy to the surface before being confronted by Takeshi Hongo, demanding them to hand him over. When soldiers from the Underground Badan Empire appear, Takeshi transforms into Kamen Rider 1 to allow Kouta, Mai, and Shu to escape. Badan then launches an attack on the surface, which draws out Armored Riders Baron, Ryugen, and Zangetsu Shin to fight back alongside Kouta. However, Gaim is attacked by Kamen Rider Fifteen, who also seeks the boy. He then uses a Lockseed that allows him to transform into the Rider Arms of the 15 Heisei Riders. Just when Gaim begins to falter against Kamen Rider Fifteen, Kamen Riders 1, 2, and V3 appear to assist. While Gaim was distracted, the Badan forces surround Shu and Mai forcing Kouta to rush back just before Shu uses his powers to allow them escape the oncoming blasts.
Kouta and Mai take Shu to Drupers where they meet Tsukasa Kadoya. After Kouta fails to inquire who Tsukasa is, a mini Narutaki appears before them, affirming that the fifteen Heisei Riders must join forces to stop the Badan Empire. Before leaving, he warns them that asking for the Shōwa Riders help is useless as they will refuse to cooperate with them. Tsukasa then departs to gather the other Kamen Riders with Kaito Kumon, while Kouta stays behind to take care of Shu. The first Rider they contact is Shotaro Hidari, who refuses to hear their plea before he finishes his job to search for some lost pets. Leaving Kaito behind to help Shotaro with his errand, Tsukasa contacts Takumi Inui who also refuses to help, claiming that his days as a Kamen Rider are over. Kamen Rider Fifteen appears to attack them, and Tsukasa transforms into Kamen Rider Decade to fight him, allowing Takumi and himself to escape harm. Some time later in a ramen shop, Takumi involves himself in an incident where a wounded runaway criminal holds Mari, a high school girl, hostage. Keisuke Jin appears and heals his wounds before convincing him to release Mari and surrender to the police. Takumi then follows Jin to his clinic, where he helps him tend to another patient. Takumi then confides in Jin about how he is haunted by the death of his friend Masato Kusaka and Jin convinces him to stay at his clinic for a while.
The next day, Takumi and Mari are attacked by the Badan Empire. In order to protect her, Takumi decides to fight again as Kamen Rider Faiz, defeating them, but in turn, Jin reveals himself as Kamen Rider X, attacking and defeating Faiz before claiming that he must find his resolve by himself. Meanwhile, Tsukasa finally convinces Shotaro to listen to his request, and asks him about Shu. Elsewhere, Shu finally remembers his past and leads Kouta to his house, where it is revealed that Shu has been dead the whole time. He remembers that before he died, his mother had been due to take him to see the lighthouse but was forced to cancel the plans when she had to work. Upset, Shu sent a picture of himself holding a piece of paper reading 'I Hate You' before then being killed crossing the road. Although he intended it just as a tease, Shu now regrets his final actions and wishes to see his mother and make amends with her. Kamen Rider Fifteen then appears to take Shu with him, and Kouta learns that he is actually Shu's father Ren Aoi. Aoi reveals that the Badan Empire intends to use Shu's powers to power up a machine known as the Mega Reverse, which can make the dead return to life while killing the living, allowing his son to come back to life. While Kamen Rider Gaim fights Kamen Rider Fifteen, Kamen Rider Decade appears and takes Shu to see his mother, but General Jark stands in his way. Kamen Riders Black and Black RX appear to defeat Jark before turning to fight Kamen Rider Decade as well, but Shotaro appears to fight them instead as Kamen Rider Joker and allows Tsukasa to keep escorting the boy. Kamen Rider Baron appears to assist Kamen Rider Joker against the Shōwa Riders while Tsukasa takes Shu to the lighthouse where his mother is staying. But before he can meet her, Kamen Rider Fifteen appears and defeats both Kamen Riders Decade and Gaim with the power of the Heisei Rider Lockseed.
Back in the present day, as the Shōwa and Heisei Riders fight and defeat each other, from the Shadow Line appears to join forces with the Badan Empire. Schwarz reasons that Badan's plans to open the underworld and unleash darkness is compatible with their own desire to eliminate light and expand the Shadow Line's domains, and sends his Kuliners to attack Kamen Rider Den-O's Den Liner which is destroyed along with Den-O. Kouta, Tsukasa, and Takumi join forces with the remaining Heisei Riders and confront the Shōwa Riders about their reasons for attacking them. Kamen Rider 1 explains that it was all the Heisei Riders' fault, as it was their attachment to their deceased important ones that empowered the Badan Empire and allowed the advent of Kamen Rider Fifteen. Meanwhile, Kurayami Taishi, the leader of the Badan forces, reveals himself as Ryo Murasame, who has infiltrated the organization to destroy it from the inside. He betrays the Generalissimo of Badan, apparently destroying the Mega Reverse Machine, but is deceived instead, when the true Mega Reverse Machine is revealed to be the entire Badan Empire base, which takes flight up in the sky. Ryo then reveals that the other Kamen Riders that have supposedly been defeated had in fact been sent to Helheim Forest, and takes the opportunity to summon them back all at once to assist him and Kamen Rider Gaim.
The Heisei and Shōwa Riders confront the Badan Empire helped by Armored Riders Baron, Ryugen, and Zangetsu Shin when the Generalissimo of Badan reveals itself as a giant monster resembling a dinosaur. from the appears, as well, to fight the monster with Gabutyra, but it proves itself too strong for just his Zyudenryu. Soon after, the and Kamen Rider Den-O arrive to assist him, combining their trains with Gabutyra into ToQ-Oh Kyoryuzin feat. DenLiner to destroy the Generalissimo. As Kamen Rider Decade rescues Shu from the Mega Reverse Machine, Kamen Riders Wizard and X are about to destroy it for good, when they are stopped by Faiz, who wants to atone for Masato's death by allowing him to be revived. Haruto argues, telling him how his desire to bring Koyomi back resulted in her resurrection into a being of evil. Jin then convince Takumi that destroying the machine is the right thing to do, and together the three Kamen Riders use their final attacks to bring it down. Kamen Rider 1 gives Kamen Rider Gaim a special Lockseed containing the powers of the 15 Shōwa Riders, allowing him to transform into 1go Arms and finally defeat Kamen Rider Fifteen, who returns to his senses. With the Badan Empire all but defeated, Kouta asks the Shōwa Riders if there is any way they can use their power to fulfill Shu's wish. The Shōwa Riders agree, and use their energy to change Shu's photo so that the message now reads 'I Love You'. Shu's spirit then reconciles with his parents one last time before passing on to the other side.
The battle is not quite over however, as Takeshi tells the Heisei Riders that the anger at how their desire to resurrect the dead helped cause the crisis was not a charade. Therefore the Shōwa Riders are still in doubt if they can leave the protection of Earth to the Heisei Riders and challenge them to a battle, with Narutaki watching it all from afar. The battle concludes when Kamen Rider Gaim risks himself to protect a single flower from Kamen Rider 1's Rider Kick, leading the Shōwa Rider to admit defeat upon realizing his act of kindness. Now truly reconciled, the Shōwa and Heisei Riders then bid farewell to each other and follow their separate ways once more.
====Alternate Ending====
The battle concludes when Kamen Rider Gaim powers up attack to use against Kamen Rider 1, but stops after realizing that the Shōwa Rider could attack him before he deploys it and admits defeat, allowing the Shōwa Riders to win. Kamen Rider 1 commends him upon realizing his act of kindness, leading the Shōwa and Heisei Riders to reconcile.

==Errors==
*The right side of the Kaixa suit's Photon Blood pieces are torn.
*Since the Shocker Greed exists only in an alternate timeline, there is no reason the Badan Empire would be able to resurrect it like they did with the other Kaijin under their command. 
*When Fifteen in Wizard Arms defeats Zangetsu Shin, both Baron and Gaim unknowingly hear Ryugen calling Zangetsu Shin "brother", even though this is a secret that they only learn about in Episode 36 of Kamen Rider Gaim.
*When Decade transforms into Hibiki while fighting Fifteen, the transformation phrase is the incorrect Form Ride (in Kamen Rider Decade, Form Ride refered to the alternate forms). When he transforms into Kuuga, however, the phrase is the correct Kamen Ride.
*When Fifteen activates his Driver's Squash Function while in Decade Arms, it instead announces 'Hibiki Squash'
*When Tsukasa put on the Decadriver, the sound for when the belt wrapped around his waist is not used, instead it is the sound of the Fourze Driver.
*When Zangetsu Shin fires the Sonic Arrow alongside Baron Mango Arms' Mango Au Lait and Ryugen Kiwi Arms' Kiwi Au Lait, the normal charging sound is heard, and the "Melon Energy" sound is not heard when the Sonic Arrow is fired.
*When Ryugen Kiwi Arms activates the Au Lait function on the Sengoku Driver, he is seen pressing the Cutting Blade once instead of twice.
*The sound editing in the film causes the background music to sometimes be louder than the dialogue in specific scenes, such as the scene when Takumi, Tsukasa, and Kouta are talking.
**One particular instance of this issue was during the scene where Mitsuzane and Takatora go through their verbal henshin phrase only to have Takatora's audio cut out completely.
*When Takumi transforms into Faiz Blaster Form, he placed the Faiz Phone in the Faiz Driver rather than the Faiz Blaster weapon.
**Furthermore, after the transformation is complete, the Faiz Phone disappears from the Faiz Driver for no apparent reason.
*When OOO uses his Medajalibur, the O Scanner announces Scanning Charge instead of Triple Scanning Charge.
*Throughout the film, it is never explained how the Badan Empire exactly managed to harness the "emotions" of the Heisei Riders to use for their resurrection machine, nor how the Kamen Riders managed to escape death via the Helheim Forest.
==Notes==
*This film has the most main rider actors returning than previous films of the Super Hero Taisen series.
*This film features the first out of suit re-appearance of Takeshi Hongo in 38 years. His last on screen appearance out of suit was in the Kamen Rider Stronger TV special All Together! Seven Kamen Riders!!. Hiroshi Fujioka previously reprised his role as Kamen Rider 1 in OOO, Den-O, All Riders: Let's Go Kamen Riders in vocal capacity and his last onscreen appearance in a Kamen Rider production was as the MPD Superintendent General in Kamen Rider Agito: Project G4.
**This film is also the first out-of-suit appearance of Keisuke Jin and Ryo Murasame following their appearances in Skyrider and Birth of the 10th! Kamen Riders All Together!! respectively
*On the official website there was a poll of having the either the Heisei or Showa Riders winning the battle, making it the first time that fans could directly influence a movie's plot. The movie poll ended one day before it premiered in theaters with Heisei as the victor by a short margin. The ending featuring the Showa Riders as victors was featured as a special on the DVD/Blu-Ray release of the movie.
*When Narutaki explains to Tsukasa in Drupers that there are now fifteen Heisei Riders, a collage of them appears. The footage of the first fourteen Heisei Riders were reused from the Bujin Riders collage seen at the start of Kamen Rider Gaim: Sengoku Battle Royale, while Gaim's is taken from his first appearance at the end of episode 52 of Kamen Rider Wizard.
*Keisuke Jin performs his inital transformation into X-Rider, using the phrase with his bodysuit manifesting as he removes the "Redizer" and "Perfecter" from the sides of his belt to form his helmet, and then snapping up the faceplate to complete the transformation, as opposed to the process following his upgrade towards the end of his series, where he used the phrase to transform while making a "X" sign with his arms.
*The events of Masato Kusaka's death are retold differently in the film. In Kamen Rider 555, Kusaka was alone when Yuji Kiba snapped his neck and the Orphnoch DNA in his body ran out which caused him to die by deteriorating into ash. In the film, the Horse Orphnoch killed Kusaka and burned him to ashes while Faiz was fighting the Arch Orphnoch (an enemy that had not shown up until the final arc of the TV series).
**According to Kohei Murakami, when he asked director Takayuki Shibasaki regarding the change, he was informed that that an "evil spirit" had taken on the form of Kusaka and it caused Takumi to misremember the circumstances regarding his death.https://sumabo.jp/20640
*The original form of Kamen Rider 1, which appeared in the first thirteen episodes of the original series, appears as a cameo during Hongo's transformation into his New Rider 1 form at the showdown between the Showa Riders and Heisei Riders.
*The cartoon sketches of notable places and cafes from previous Kamen Rider seasons can be seen during the credits such as Snack Amigo (Kamen Rider), Cous Coussier (OOO), Jaracanda (Blade), Antique Shop Omokagedo (Wizard), Coffee House COL (X), Milk Dipper (Den-O), Café mald'amour (Kiva) and others.
*In the post credits scene, the film is dedicated to Tohru Hirayama, the co-creator of the Kamen Rider Series, and Takao Nagaishi, the main director of Agito, 555, Blade, and Kabuto. Both men passed away the year before in 2013.
