Kamen Rider ZX

Ryō Murasame is an aircraft pilot, one day he was taking his sister out on a ride along the Amazon when they were shot down by an UFO. They survived, captured by Badan Empire with his sister killed while Ryo became the Combt Roid known as ZX. His memory is erased by the Badan Empire and worked as their agent of evil. This does not last long as an accident occurs which causes Ryō to regain his memory and escapes Badan. A year later, Ryō begins his attack on Badan as they finish the preparations on their doomsday weapon: the Space Break System. However, a coordinated attack by the Kamen Riders disables the Badancium 84 supplies needed for Space System to work When Ryō arrives, he thinks Kamen Rider V3, Riderman and Kamen Rider Super-1 are enemies until they get him to listen as only on truck full of Badancium makes it to the Badan's base run by Ambassador Darkness.

After being shown a video detailing the history of Kamen Riders 1 to Super-1, Ryō is amazed that there are others like them before joining the Kamen Riders in raiding the base. However, he encounters his former comrade Mikage who forces him to fight as Tiger Roid. After being forced to kill his friend, ZX joins the Kamen Riders as they battle not only Ambassador Darkness and the Combat Roids, but also monsters from the previous organizations. 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 as its Great Leader appears and bid the Riders farewell. Soon after, ZX joins the Kamen Riders as their 10th member.
