Kamen Rider 4

Kamen Rider 4 (仮面ライダー4号) is the fourth Kamen Rider created by Shocker following Kamen Rider 3 and the original Double Riders, Kamen Rider 1 and Kamen Rider 2. Created to accompany the appearance of Rider 3, who originated in the manga Kamen Rider 3 vs. General Black, in the movie , Rider 4 appeared in a DVD special accompanying the film's release.

Compared to his predecessors, he is truly evil with no signs of redemption, as Rider 4 is actually a robot, instead of a cyborg created via kidnapped human prodigies that the 3 numerical Riders made before him were like.

Kamen Rider 4 was shown after credits when Shocker revealed that the failure of Kamen Rider 3's attack was not the end of their plans to use the History Modifying Machine and conquer Earth.

Kamen Rider 4
Kamen Rider 4 was born as a plan when Shocker scientists recovered the functioning remains of the History Modifying Machine and began messing with the machine. As they did, they trapped the present in a temporary timeloop in an alternative timeline, one where Mach was alive even after the events of Shocker's previous attempt with the machine. As Kamen Rider Drive sacrificed his life to save Mach in the third time loop, and another time loop started, Kamen Rider 4 was near completion, his Sky Cyclone waiting for him in another hangar.

He is eventually defeated by Kamen Rider Drive Type Formula.
