Kamen Rider 4

, alternatively designated , is the titular major antagonist of D-Video Special: Kamen Rider 4. He was a cyborgKamen Rider Pia Vol.2 created by Shocker following their failed attempt by Kamen Rider 3 to alter the timeline. 
==History==
===Super Hero Taisen GP===
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. 
During the climax of their fight, Kamen Rider 4 clashed his Rider Kick against Kamen Rider Drive Type Formula's Formuladrop, which he had initially blocked with his own Rider Kick, but Drive broke the clash by twisting his kick as so he went airborne while 4 hit the ground, his leg damaged when he stood back up. When Drive came back down to resume his Formuladrop, 4's leg was too damaged to attempt another Rider Kick clash, and resorted to clashing it with a Rider Punch. Despite the power, the Rider Punch was snuffed out, and Drive was pushing 4 back. Drive resorts to throttling Shift Formula 5 times, then an additional 3 times after ignoring some warnings from Krim, finally overwhelming 4 and destroyed him.

==Notes==
*Created to accompany the appearance of Rider 3, who originated in the manga Kamen Rider: Rider 3 vs. The Demon of General Black, in the movie , Rider 4 appeared in a DVD special accompanying the film's release.http://www.famitsu.com/images/000/071/631/54ddb2da61011.html
*The possibility of his existence was raised in 1972's Televi-Magazine article, "100 Secrets of Kamen Rider". The producer Toru Hirayama had also considered to making Kazuya Taki as Kamen Rider 4 in the TV series instead of Joji Yuki, but this idea fell through.
*Like Rider 3, Rider 4's design is similar to the Kamen Rider designs in the The Series. This design is also an homage to Riderman, the fourth main Kamen Rider, who had his mouth exposed.
*Rider 4's wingsuit is actually incorrectly built, as it lacks the flaps in-between his legs.
*Kamen Rider 4 is the first rider to have a plane as his Rider Machine.
*In the music video of the song Time, Rider 4's voice actor Matsuoka played a man with a "Sophia Air Force" badge along with a epaulet with a logo similar to Shocker's. He looked at Drive expressively, with Kamen Rider 4's similar mannerisms. This may hint at him being Rider 4's counterpart in the original timeline.
**According to Matsuoka, his personal head-canon was that Katsumi Daido is the true identity of Kamen Rider 4.https://twitter.com/mitsurumatsuoka/status/573031096104849408 In fact, he attempted to adlib Eternal's catchphrase "Now, enjoy your hell!", but this was rejected by the director.
