Kyoichiro Kuroi

"Win and you are just, lose and you are evil."

- Kamen Rider 3's words to Drive.

Kyoichiro Kuroi (黒井 響一郎) is Kamen Rider 3 (仮面ライダー3号), alternatively designated Shocker Rider 3 (ショッカーライダー3号), making his first appearance in ' and later 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
Kamen Rider 3 creation was caused by using of History Modifying Machine developed by Roidmude 089 disguised as Doctor D using the very last of his cells.

He attack Gō Shijima, just only for his test drive before furthers Shocker's plan to transport him into 1973.

Shocker sent Kamen Rider 3 back in time in 1973, right after the Double Riders defeated the Great Leader of Gel-Shocker. He appeared before the riders and defeated them. The Liner crews arrived too late to prevent Shocker from rising again and changing the course of history itself, with Kotaro Minami remaining as BLACK, and also resulting in many Riders being brainwashed. However, there are the minority of Riders who were not affected by the changing of history, such as the Liner crews (notably from DenLiner and ZeroLiner), Over Lord powered Kouta Kazuraba who are trying to resist the reign of Shocker. Because of this he is known as the "Rider who should never have existed."

In an altered world, now he's on a run from both Riders led by Kamen Rider V3 and Shocker, only Shinnosuke Tomari, Yuto Sakurai, and Go Shijima who appears to assist him to clear his name as a "Rider". Later, he assists the other Kamen Riders in their battle against Shocker. After the Rider Robo housing the History Modifying Machine was destroyed, all of Shocker's changes to history were undone, restoring the timeline back to normal. This effectively negates Kyoichiro's existence as well, causing him to vanish.
