|This article is about a/an Mirror Monster in Kamen Rider Ryuki.|
Zenobiter (ゼノバイター Zenobaitā, 11, 38, 43 & 44): A blue-colored male longhorn beetle Mirror Monster that is equipped with a large boomerang sharp enough to cut through iron.
Zenobiter feasted on people in a train car on the Fukutoshin Line. He used his boomerang to knock away the weapons Ryuki tried summoning, but was tricked by Ryuki into deflecting the Drag Claw while the Rider instead dove for the Drag Saber lying on the ground. Zenobiter was then destroyed by Ryuki's Dragon Rider Kick.
A second Zenobiter appeared in a crowd of monsters on a rooftop, only to be destroyed by Knight's Hishou Zan.
Another Zenobiter was part of a group of Mirror Monsters who surrounded Yui when she tried stranding herself in the Mirror World, but was one of those controlled by Shiro Kanzaki to protect Yui from the other Monsters.
A Zenobiter appeared in Shinji's dream, destroyed by Knight's Hishou Zan.
