Shocker Town

Shocker Town (ショッカータウン) was the base of Shocker in an altered history written by the History Modifying Machine in which the Double Riders 1 and 2 were assassinated by Shocker's Kamen Rider 3 in 1973. Intended by the Great Leader of Shocker as the final trap for the rebel Kamen Riders, Kyoichiro Kuroi falsely claimed it to be Rider Town (ライダータウン).

Telling Kamen Rider Drive of this Rider Town, Kuroi claimed it to be the residence of Riders 1 and 2, who survived their deaths by transfering their respective consciousness into artificial brains, where all the Kamen Riders who oppose Shocker gather. Hunted by brainwashed Shocker Riders, Rider 3, Drive and Kamen Rider Mach pursued the Rider Town together. They would be joined by Kamen Rider Zeronos, who ultimately made it there first by himself. He was led by what appeared to be the voice of the Double Riders to the home of Takeshi Hongo, where he was met by Tobei Tachibana, who guided him to the residence of the Double Riders' brains only for Zeronos to find no Kamen Riders waiting, with what he heard as Rider 1's voice revealed to be the Great Leader of Shocker while "Tobei Tachibana" revealed himself to be Hiruchameleon. Upon this revelation, the "Rider Town" was unmasked as Shocker Town as the computerized brain which housed the Great Leader of Shocker rised from the Hongo mansion, with Kyoichiro Kuroi making his appearance leading Shocker's monsters. It was at this moment that Shinnosuke Tomari arrived, having seen through Kamen Rider 3's deception, and challenged Kyoichiro Kuroi to a Rider Grand Prix.
