Evildiver (エビルダイバー Ebirudaibā) is a Mirror Monster that was contracted to 3 different people at different Times in Kamen Rider Ryuki. Originally, it was contracted to the original Kamen Rider Raia, Yuichi Saito. However, after Yuichi was eaten by the Mirror Monster, GuldThunder, it became contracted to Miyuki Tezuka who became Raia in place of Yuichi. After Tezuka's death, it was then contracted to Kamen Rider Ouja. This makes him the only Mirror Monster to be contracted to 3 different people.

Together with Venosnaker and Metalgelas, this monster became one of the building blocks of the composite Contract Monster Genocider.


Evildiver appears as Raia's Contract Monster initially, but later after Raia's death, it was contracted by Kamen Rider Ouja. It represents a mechanical stingray. A number of Raia's (and later Ouja's) weapons & Advent Cards are based off of Evildiver.

Evildiver made its first appearance in a battle against Ren and Tezuka in which it hit Ren with a half-powered Final Vent, so as to not completely destroy him. It later appeared for a Final Vent when Tezuka had his revenge on GuldThunder, the Monster that ate Evildiver's previous contractor, Yuichi Saito. After Tezuka was killed by Asakura, Evildiver was immediately contracted by Asakura and became the final component to Genocider.

At one point, Evildiver started to go out of control as Asakura hadn't been feeding it life energy from monsters. It began to attack Asakura in defiance but was eventually fed before Asakura completely breached the Contract.

As Asakura didn't die from implications of the Rider War, it isn't known what happened to Evildiver after the war, but at the end, it's implied that because time was turned back and the war didn't exist, neither did the Mirror Monsters and hence, neither did Evildiver.

Kamen Rider Ryuki: Episode Final

Evildiver first appears when Asakura summons him to ram Shinji due to him disturbing Asakura's battle with Miho Kirishima. Later, Evildiver appeared when Asakura used his Unite Vent card to combine his Evildiver with Metalgelas and Venosnaker into Genocider. Evildiver was also destroyed alongside Metalgelas and Venosnaker when hit by Kamen Rider Ryuga's Final Vent.
