But as revealed in Kamen Rider OOO onwards, there are some surviving members of the Shocker organization, even from Badan Empire who went into hiding to gather data of the Kamen Riders' battles against some of their respective kaijins many years. But during the events of Super Hero Taisen GP: Kamen Rider 3, Shocker's remaining scientists created a History Modification Machine that they use to send a time displaced cyborg called Kamen Rider 3 back in time to destroy the Double Riders in the aftermath of Gel-Shocker's defeat, creating a new timeline where Shocker rules the world with some Kamen Riders in their service. Luckily, the apparent destruction of the History Modification Machine restores the timeline (with the exception of Go Shijima/Kamen Rider Mach who was killed by Cheetahkatatsumuri), only to be found out during the events of D-Video Special: Kamen Rider 4 that Shocker secretly uses it to create time loops and alters the timeline once more, allowing to create Kamen Rider 4, as well as the revalation that they have been targeting Takumi Inui, due to his sacrifice-less wish to ensure that no one dies like what happened to one of his old allies to create a loop. As Takumi is about to destroy the machine, the Great Leader of Shocker appears with an appearance identical to Takumi's. In the end, Takumi destroys the machine and disappears alongside the modified timeline, restored back to its original timeline once more. Though most of his allies who do not originate from Kamen Rider 555 TV series like from Kamen Rider Drive, and even Kamen Rider Den-O's Kamen Rider Zeronos do not remember if they had encountered Takumi, only some of Takumi's old friends from Kamen Rider 555 TV series, including Naoya Kaido still remember Takumi.
