Kyoichiro Kuroi

Kyoichiro Kuroi (黒井 響一郎) is Kamen Rider 3 (仮面ライダー3号), making his first appearance in . He is the third Kamen Rider cyborg created by Shocker following the original Double Riders, Kamen Rider 1 and Kamen Rider 2, that came before him decades ago.

History
Not much known about Kamen Rider 3 in the main live-action universe. It is only known his existence was caused by a timeline alteration in 1973.

After the Double Riders defeated the Great Leader of Gel-Shocker, Kamen Rider 3 later appeared before the riders and defeated them, allowing Shocker to rise again and changing the course of history itself, with Kotaro Minami remaining as BLACK, and also resulting in many Riders being brainwashed, for example Kamen Rider Leangle who becomes the new leader of Shocker and imprisons Kamen Rider Blade. However, there are the minority of Riders who were not affected by the changing of history, such as Go Shijima, the Liner crews (notably from DenLiner and ZeroLiner), Over Lord powered Kouta Kazuraba, and Shiro Kazami, and are trying to resist the reign of Shocker. Because of this he is known as the "Rider who should never have existed".

Later, he assists the other Kamen Riders in their battle against Shocker to find out what caused the timeline alteration and why he exists.
