Birth of the 10th! Kamen Riders All Together!!

is a Japanese television special serving as the eighth installment of Toei Company's Kamen Rider Series. The special follows Ryo Murasame, the tenth person to don the Kamen Rider title, as he fights against the Badan Empire who killed his sister. 
Unfortunately, the special did not lead to a Kamen Rider ZX series to which the franchise went on a three and a half-year hiatus until the premiere of Kamen Rider Black.
The average rating of the special was 6.5%.
==The Tenth Rider==
Following the finale of Kamen Rider Super-1 in October 1981, the Kamen Rider Series once again stopped airing on TV. However, a tenth Kamen Rider, ZX, debuted in an eponymous manga series which began serialization in the July 1982 issue of the Japanese publication Television Magazine. ZX was then featured in a short radio drama broadcast during a special episode of All Night Nippon hosted by Shotaro Ishinomori on August 14, 1982, commemorating the character's official debut, before making his live-action television one in the special Birth of the 10th! Kamen Riders All Together!!.
==Story==
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 Combat Roid known as ZX. His memory is erased by the Badan Empire and worked as their agent of evil. This doesn't 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 Spacetime Rupture System. However, a coordinated attack by the Kamen Riders disables the Badanium-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 one truck full of Badancium makes it to the Badan's base run by Kurayami Taishi.
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 Kurayami Taishi and the Combat Roids, but also monsters from the previous organizations. When Kurayami Taishi uses the Spacetime Rupture System on the Kamen Riders, they synch their powers with ZX using his ZX Kick to kill Kurayami Taishi and destroy Badan's base as its Great Leader appears and bids the Riders farewell. Soon after, ZX joins the Kamen Riders as their 10th member.
