Genocider

Genocider is the product of a merged EvilDiver, Metalgelas and Venosnaker.

Appearance
Obtained through a Unite Vent, Genocider appears as a merged form of Kamen Rider Raia's EvilDiver, Kamen Rider Gai's MetalGelas and Kamen Rider Ouja's Venosnaker. All three components of Genocider are contracted to Asakura (Kamen Rider Ouja) and are used as either intimidation or to perform a Final Vent.

History
Genocider first appeared after Asakura contracted EvilDiver, & Metalgelas as well as his original contracted monster Venosnaker. On many occasions, Asakura would summon Genocider merely to indimidate the other riders and it would rarely be involved it in battle. When it was however, it commonly ran at the opponent and shot venom at them. Genocider played a role in the Death of Goro who had taken over Usage of The Zolda Suit and the destruction of Magnugiga. It is unknown what happened to Genocider after Asakura died. However, The end implies that he never existed afterwards.

Uses
Genocider plays a pivotal role in his Final Vent where a Vortex opens up on his chest which then allows Asakura to kick his enemy into it, supposedly killing them.
