## Plot summary

Ryo Murasame is an aircraft pilot. One day he is taking his sister out on a ride along the Amazon when they are shot down by a UFO. They survive only to be captured by the Badan Empire. His sister is killed, while Ryo becomes the Combat Roid known as ZX. His memory is erased by the Badan Empire, and he works as their agent of evil. This doesn't last long; an accident occurs which causes Ryo to regain his memory and escape Badan. A year later, Ryo begins his attack on Badan as they finish the preparations for their doomsday weapon: the Space Break System. A coordinated attack by all of the Kamen Riders disables the Badancium 84 supplies needed for the Space Break System to work. When Ryo arrives, he Believes Kamen Riders V3, Riderman and Super-1 are enemies. The other Riders get him to listen to them and only one truck full of Badancium 84 makes it to Badan's base run by Ambassador Darkness.
After being shown a video detailing the history of Kamen Riders 1 to Super-1, Ryo is amazed that there are others like him. He then joins the Kamen Riders in raiding the base. However, during the raid, he encounters his former comrade, Mikage, who forces him to fight as Tigeroid. After being forced to kill his friend, ZX joins the other 9 Kamen Riders as they battle Ambassador Darkness, Monster Roids, and the Combat Roids. When Ambassador Darkness uses the Space Break System on the Kamen Riders, they synch their powers with ZX, using his ZX Kick to kill Ambassador Darkness and destroy Badan's base even as its Great Leader appears and bids the Riders farewell. Soon after, ZX joins the ranks of the Kamen Riders as their 10th member.

## Characters

* Ryo Murasame/Kamen Rider ZX (村雨 良／仮面ライダーZX, Murasame Ryō/Kamen Raidā Zekurosu): Ryo is an aircraft pilot, he lives with his sister and it's presumed he lived with his parents. He is impulsive and hesitates to trust the veteran Riders when he first encounters them. He has the most cybernetic body out of any Kamen Rider created thus far. His body has many hidden abilities reminiscent of a ninja, including shuriken and chain-sickles. He does not give himself the Kamen Rider moniker until the final confrontation.
* Rumi Ichijō (一条 ルミ, Ichijō Rumi): She is a girl who is the daughter of a doctor who was killed by Badan. She gives Ryo temporary peacefulness.
* Dr. Hajime Kaidō (海堂 肇博士, Kaidō Hajime Hakase): He is Ryo's father's friend, is a researcher of biochemistry, and is also a teacher at a university. He cooperates with Ryo unstintingly.
* Shizuka Murasame (村雨 しずか, Murasame Shizuka): She is a newspaper reporter and Ryo's elder sister. While investigating rumors of a UFO with Ryo, she is caught by Badan. Since she got to know Badan's secret, she is executed in an electric chair.
* Shiro Kazami/Kamen Rider V3 (風見 志郎／仮面ライダーV3, Kazami Shirō/Kamen Raidā Bui Surī): He is the oldest Rider to appear out of his suit. He is the leader of the Japanese division of the Rider Organization while Kamen Riders 1 and 2 are in America. Apparently, he is the strongest of the veteran Riders as he was the only one able to hold off ZX.
* Joji Yuki/Riderman (結城 丈二／ライダーマン, Yūki Jōji/Raidāman): The second oldest Kamen Rider in the special. He is V3's partner in leading the Kamen Riders when Kamen Riders 1 and 2 are away.

### Badan Empire

The Badan Empire (バダン帝国, Badan Teikoku) claims to be the successor of all previous groups that attempted to conquer the world but fell without fulfilling that ambition. In Kamen Rider Spirits, several references infer that the Badan Empire was actually created by an alien entity, and supported terrorist groups starting with Shocker secretly working towards bringing the true form of their leader to Earth. Badan later resurfaces during the events of Ressha Sentai ToQger vs. Kamen Rider Gaim: Spring Break Combined Special and Heisei Rider vs. Shōwa Rider: Kamen Rider Taisen feat. Super Sentai.
* The Generalissimo of Badan (バダン総統, Badan Sōtō): A giant skull that appears after Ambassador Darkness' death. It disappears after laughing at the ten Riders. Dr. Kaidō said that it is the energy of an evil spirit. In the manga, the leader is identified as Great Leader JUDO (大首領JUDO, Daishuryō JUDO), JUDO has a Kamen Rider form called Susanoo (スサノオ), a golden version of ZX with the ability to transform into nine Shōwa Kamen Riders. He has his own language, which he can telepathically compel others to understand.
* Ambassador Darkness (暗闇大使, Kurayami Taishi): He is the leader of the Badan Empire and the brother of Ambassador Hell of the organization Shocker. He is a maniacal man who is hellbent on getting what he wants. He is the one that ordered Ryo's plane to be shot down, thus killing his older sister. He is destroyed by Kamen Rider ZX's ZX Kick. In the manga, he is transformed into Southern Cross (サザンクロス, Sazan Kurosu) who is a horned turbanlike monster.
* Eisuke Mikage/Tigeroid (三影 英介／タイガーロイド, Mikage Eisuke/Taigāroido): He is a ĺ that is able to produce a wide variety of artillery from his body and has attributes and abilities equal to Ryo, thinking that power is justice.
