Metalgelas (Ryuki)

Metalgelas is a Mirror Monster that was originally contracted to Kamen Rider Gai : Jun Shibaura but was later contracted to Kamen Rider Ouja : Asakura Takeshi. This makes him one of 5 Mirror Monsters that had more then 1 Contractor. and the 2nd Mirror Monster Component of Genocider.

Appearance
Metalgelas appears initially as Gai's Contract Monster but after Jun is killed, Asakura contracts him. Metalgelas resembles a Rhino and can reach extrememly high speeds. He also has tough skin that can crush a moving car.

History
Metalgelas originally assisted Jun in both destroying monsters and attacking other Riders. However, once Jun died at the hands of Asakura, Metalgelas attacked many people who it believed resembled Asakura (as it was trying to avenge it's Contractor). However, Asakura was able to successfully contract Metalgelas and after Asakura obtained Evildiver also, it was able to merge with Evildiver and Venosnaker to creat Genocider.

Metalgelas began to once again turn on Asakura after he neglected to feed Metalgelas life-force Energy from Mirror Monsters. In defiance, he attacked Asakura once before finally being fed just before Asakura completely breached his contract.

As Asakura did not die at the hands of a Rider, it is not known what happened to Metalgelas. However, the End implies that because the Rider War was made non-existant, that Metalgelas was also made non-existant.

Uses

 * Metalgelas's Horn is used whenever Gai activates a Strike Vent
 * Metalgelas also allows Gai to ride him during a final Vent in which he pierces the opponent with both Gai himself and it's horn.
