Kamen Rider Gaim: Advance to the Last Stage title
The film begins in the planet where Kouta Kazuraba and Mai Takatsukasa settled after the events of Kamen Rider Gaim when a mechanical life form who introduces itself as Megahex kidnaps Mai and fights Kouta while obtaining data from his memories, which he uses to open a portal to Earth in order to attack it. Despite using the power of the Kiwami Arms, Kamen Rider Gaim is defeated and seemingly destroyed by Megahex over the skies of Zawame City before the astonished eyes of the other Beat Riders. Mitsuzane Kureshima, being the only Rider left with his Sengoku Driver, fights Megahex and his forces as Kamen Rider Ryugen, but is forced to flee when the enemy summons a mechanical copy of Ryoma Sengoku, as Kamen Rider Duke Dragonfruit Energy Arms, that overpowers and injures him, but not without taking with him one of the Drivers used by his army of artificial Kurokage Troopers.
As Mitsuzane is treated by the other Beat Riders, he has a vision of Mai asking for help in his dreams and upon awakening, they find one of the Helheim Vines from which Takatora Kureshima obtains a Melon Lockseed, combining it with the Driver obtained from his brother to become Kamen Rider Zangetsu once again. In the next day, the Kureshima brothers return to fight back, with Zangetsu confronting and defeating Duke while Ryugen fights through an army of artificial Roidmudes to rescue Mai. Once the three are reunited, Mitsuzane entrusts a Melon Energy Lockseed to Takatora who uses it to become Kamen Rider Zangetsu Shin using the Genesis Driver he obtained from Ryoma’s body. However, Megahex empowers itself with the Kiwami Lockseed he got from Kouta’s body to fight them. Despite reclaiming the Lockseed, Mai and the Kureshima brothers are about to be killed by Megahex when a revived Kouta emerges from it. The three Riders then destroy Megahex with their power, just to find that it was only one of many copies of the real Megahex, whose core lies on the massive spaceship on the other side of the portal and watch helplessly as the copies spread.
Kamen Rider Drive: The Challenge from Lupin
The story then shifts back to some time before, as the police confronts a criminal known as “Phantom Thief Ultimate Lupin”, Shinnosuke Tomari and his partner Kiriko Shijima arrive at the scene and discovering that the thief is actually a Roidmude, Shinnosuke confronts it as Kamen Rider Drive, but fails to prevent it from escaping. In the next day a letter arrives at the Special Investigations Division with a challenge from Lupin, claiming that he will steal a precious artifact while it is being escorted by the police. Shinnosuke joins the escort, but once again fails to prevent Lupin from escaping. Having a hint of the enemy’s identity, Mr. Belt takes Shinnosuke to an abandoned mansion where they discover that Cyberoid ZZZ, an artificial Roidmude created by Krim is missing. Lupin then appears and reveals that he is actually ZZZ, who came to life upon coming into contact with an old, dying master criminal known as Zoruku Tojo. In the occasion, Chase arrives at the scene determined to destroy ZZZ, deeming him unfit as a Roidmude, but the enemy drives him away after transforming into Kamen Rider Lupin. Drive then fights Lupin just to be defeated as well and Mr. Belt sacrifices itself to protect Shinnosuke from a fatal blow, becoming unresponsive.
First appearance of Kamen Rider Mach
While being consoled by the Shift Cars, Shinnosuke has an idea and leaves in a rush. Some time later, a white-colored Kamen Rider appears at the Drive Pit in the middle of the night. In the next day, the Special Investigations Division receives another letter apparently sent from Lupin, but upon arriving at the place mentioned there, they are greeted by Shinnosuke, who reveals that he figured that at some moment Lupin switched places with Kiriko and is impersonating her since then. Lupin then reveals that the real Kiriko is held hostage somewhere else, and Shinnosuke must choose between chasing after him or rescuing his partner. Shinnosuke decides to chase after Lupin instead, and while Tridoron rescues Kiriko, Shinnosuke regains the ability to transform into Kamen Rider Drive once Mr. Belt awakens. Assisted by Kiriko and Tridoron, and with an unexpected help from Masshin Chaser, Drive defeats Lupin, but while Chaser departs, having the white Kamen Rider following him, ZZZ’s body is stolen by one of the Megahex copies who fuses itself with it becoming ZZZ Megahex, and Shinnosuke chases after him.
Movie War Full Throttle
Back to the present, Gaim, Ryugen and Zangetsu Shin confront an army of artificially created Inves and Roidmudes when Drive arrives to assist them. In response, ZZZ Megahex creates an artificial copy of Kaito Kumon to fight for him, but it rebels against him instead, transforming into Kamen Rider Baron. The Roidmudes Heart, Brain and Mashin Chaser also arrive to fight Megahex as well, discontent at him for stealing Roidmude technology. Leaving the enemy force to the others, Drive and Gaim fight ZZZ Megahex together, but the enemy regenerates upon taking their attacks, until Mai arrives and gives them the idea of combining their powers, producing the Shift Fruits Car and the Drive Lockseed, allowing the two Riders to use each other’s powers and destroy its body. However, ZZZ’s core remains intact and is sent to the Megahex mothership, prompting the two Riders to chase after it on an empowered Tridoron, which they use to reach the nucleus of the ship on the orbit of Jupiter and destroy it, defeating Megahex once and for all, while incapacitating the artificial Inves and Roidmudes, including the artificial Baron as well. After the battle, Kouta and Mai are about to return to their planet when they are approached by their friends, who appear to give them a proper farewell. Meanwhile, a Bat Viral Core containing Lupin’s memories, briefly appears before Shinnosuke, warning him that they will meet again.A good film, but a bit complex as it feels like a two part episode crossover, it all comes together in the end thou and its always nice to see riders teaming up
