Evildiver (Ryuki)

EvilDiver is a Mirror Monster that was contracted to 3 different people at different Times in Kamen Rider Ryuki. Originally, it was contracted to Kamen Rider Raia: Yuichi Saito. However, after Yuichi was eaten by the Mirror Monster Guldthunder, it became contracted to Tezuka Miyuki who became Raia in Place of Yuichi. After Tezuka's Death however, it was then contracted to Kamen Rider Ouja: Asakura Takeshi. This makes him the only Mirror Monster to be contracted to 3 different people.

He is also one of the 3 Mirror Monsters that merge to form Genocider.

Appearance
EvilDiver appears as Raia's Contract Monster initially but later after Raia's Death, is contracted to Kamen Rider Ouja. It represents a Mechanical Stingray. A number of Raia's (And later Ouja's) Weapons & Cards are based off of EvilDiver.

History
EvilDiver made it's first appearance in a battle against Ren and Tezuka in which it hit Ren with a Half-Powered Final Vent, 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 had not been feeding it life-force energy from monsters. It began to attack Asakyura in Defiance but was eventually fed before Asakura completely breached the Contract.

As Asakura did not die from implications of the Rider War, It is not known what happened to EvilDiver after the War, but at the end, it is implied that because Time was turned back and the war did not exist, neither did the Mirror Monsters and hence, neither did Evildiver.
