Perfecter in Kamen Rider Taisen.

For the first 27 episodes (and later in Kamen Rider Taisen), Keisuke Jin used the phrase "Set Up" (セタップ Set Appu) and jumps into the air with his bodysuit manifesting as he removes the Redizer and 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 being powered up by the Mercury Circuit.


Revived Apollogeist is equipped with a Perfecter on his helmet following his first defeat by X-Rider. Likewise, the alternate Apollogeist from the World of X-Rider, Guy, was revived by the Government of Darkness after being killed by that world's X-Rider. This A.R version has the ability to take the life force of other people to augment someone else as Guy (and Tsukasa on one occasion) frequently demonstrated.

In World of Stronger, Yuriko Misaki has a Perfecter to protect her head and her face, giving her helmet a more Rider-like appearance.

Kamen Rider G3-X

Kamen Rider G3-X's faceplate is also called "Perfecter". Although they have no physical connection.[1]
