Volcancer (Ryuki)

Volcancer appeared in 2002 TV series called Kamen Rider Ryuki. Volcancer (ボルキャンサー Borukyansā) is a Mirror Monster that is contracted to Kamen Rider Scissors: Masashi Sudo in Kamen Rider Ryuki.

Volcancer was the first example of the consequences that a Rider will face if they breach their contract with a Mirror Monster.

Volcancer appears as Scissors' Contract monster and resembles a humanoid crab. His hands are giant pincers which are occasionally used by Scissors for attacks.

Volcancer first appeared to be attacking a woman. Shinji, who mistakenly took it for an uncontracted monster fought it before running into his contractor, Kamen Rider Scissors.

After that, when Masashi's Deck was destroyed by Ren in the Mirror World during a battle. Volcancer attacked, crushed and ate Masashi as the destruction of his deck and cards had also resulted in a breach of his contract with the monster. Volcancer, now uncontracted to a rider, attacked Ren and was initially winning until Shinji appeared. Volcancer was eventually destroyed by Ryuki's Dragon Rider Kick and its essence absorbed by Darkwing when Ryuki told Dragredder not to absorb it.

In the World of Ryuki, Volcancer assists Scissors as Contract Monster in the Kamen Rider Trial. During the Rider Battle, Scissors tricked Verde after the latter was gaining the upper hand, saying that he lost. After Verde let his guard down, Scissors summoned Volcancer to attack Verde, removing from him the trial at the same time.

As a Mirror Monster Volcancer was one of the monsters seen fighting Ryuki during his segment of the All Rider battle.
