OOO, Den-O, All Riders: Let's Go Kamen Riders
A mishap caused by the Greeed Ankh unintentionally altered the timeline which enabled Shocker to utilize the Core Medal to create the Shocker Greeed which defeated the Double Riders and seemingly erased the legacy of the Kamen Riders from history. In 2011, after Kamen Rider New Den-O's attempt to repair the damage, he along with Kamen Rider OOO and M-Ankh awaited execution. However, it was revealed the Double Riders had their brainwashing removed by a Shocker scientist.

The Double Riders joined with New Den-O and OOO to fight Shocker's forces, but were eventually defeated. When the order was given to kill everyone, V3 suddenly appeared, asserting that there were more than four riders. V3 was soon followed by all the other revived riders that came after him, including X-Rider, as even though Rider history was changed, the people's memories haven't changed.

After the riders were united, they faced off against Shocker's Great Leader. Later, when joined by a force of extra riders, X-Rider and all the other riders got on their motorcycles and performed the "All Rider Break", ramming into the Rock Great Leader and defeating it once and for all.

X-Rider
For the first 27 episodes, Keisuke's used the phrase Set Up (セタップ, Setappu) and jumps into the air with his bodysuit manifesting as he removes the "Redizer" & "Perfecter" from the sides of his belt to form his helmet and then snap up the faceplate to complete the transformation. From 28 onward, Keisuke uses the phrase "Dai Henshin!" (大変身！, Dai Henshin) to transform while making a "X" sign with his arms after V3 gives him Mercury Circuit(マーキュリー回路), which could greatly power up X.

As a Kaizorg, Keisuke is a master of undersea combat. His exoskeleton is made of a special super alloy call Special Structure that allows him to survive the heavy pressure of ten thousand meters below sea level with an artificial lung to breathe underwater.
