Super Hero Taisen GP


An incomplete Rider 4

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. Deathmatch! The Kamen Rider Died Three Times!!

Formula Drop

Kamen Rider 4 vs. Drive Type Formula.

During the climax of their fight, Kamen Rider 4 clashed his Rider Kick against Kamen Rider Drive Type Formula's Formula Drop, 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 Formula Drop, 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. Duel!

Behind the scenes


Kamen Rider 4 is voiced by Mitsuru Matsuoka (松岡 充 Matsuoka Mitsuru), who also sang the theme song for the special this Rider appears in. He previously portrayed Katsumi Daido (Kamen Rider Eternal) in Kamen Rider W Forever: A to Z/The Gaia Memories of Fate and Kamen Rider W Returns: Kamen Rider Eternal.

Kamen Rider 4's suit actor is Eitoku (永徳 Eitoku).[3]


  • Kamen Rider 4 is the first rider to have a plane as his Rider Machine.
  • Like Rider 3, Rider 4's design is similar to the Kamen Rider designs in the reboot films.
    • His human-like mouthplate is similar to the one used by certain Super Sentai teams, such as the ZyurangersIcon-crosswiki.
      • This design is also an homage to Riderman, the fourth main Kamen Rider, who had his mouth exposed.
KR-3&4 mentioned in 1971 magazine
  • The possibility of his existence was raised in 1972's Televi-Magazine article, "100 Secrets of Kamen Rider".
  • 4's wingsuit is actually incorrectly built, as it lacks the flaps inbetween his legs.
  • Kamen Rider 4's ability of flight may also be in homage to Skyrider, who was actually the first Rider to be created by an actual Shocker successor (Neo-Shocker) in regular continuity and not by a group associated tangentially to Shocker (such as Destron, G.O.D., Garanda, Black Satan or the Delza Army)
    • His dark-green suit and brown chestplate is similar to Skyrider's original dark colored suit prior to obtaining an upgrade by the power of the first seven Riders.
  • In the music video of the song Time, Mitsuru 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 "chin-touching" behavior. This implies that he may be Rider 4's counterpart in the original unaltered timeline.
  • In the stage show Kamen Rider Drive: Special Event, there is another Kamen Rider 4 called Akagi.
