Birth of the 10th! Kamen Riders All Together!! (１０号誕生！仮面ライダー全員集合!! Jūgō Tanjō! Kamen Raidā Zen'in Shūgō!!) is a Kamen Rider Series Japanese TV special that aired on January 3, 1984. It is a special meant to celebrate the birth of Kamen Rider ZX, the 10th person to don the Kamen Rider title. Unfortunately, it did not lead to a Kamen Rider ZX TV series and the Kamen Rider Series would rest once again until the premiere of Kamen Rider Black over three and a half years later. This special is often treated as a one-episode season by Toei.
