|This article is about a/an Mirror Monster in Kamen Rider Ryuki.|
Psyco-Rogue (サイコローグ Saikorōgu) is a sole Mirror Monster that was contracted by The Alternatives.
Psyco-Rogue is a Mirror Monster that resembles a humanoid cricket. This contract monster has white armor with black accents while Alternative's armor was black and Alternative Zero's was black with white accents, contrary to other Riders whose armor were similar with their contract monster.
Psyco-Rogue could transform into a motorcycle called the Psycoroader (サイコローダー Saikorōdā). The Final Vent move Dead End (デッドエンド Deddo Endo) transforms Psyco-Rogue into a motorcycle then an Alternative and motorcycle spin-out faster and faster until they ram into the opponent.
Through the use of certain Advent Cards, parts of Psychorogue's body can be used by Alternative as weapons or other equipment.
- Slash Dagger (スラッシュダッガー Surasshu Daggā): A sword derived from Psyco-Rogue's forearms. It is summoned with Alternative's Sword Vent card.
Psyco-Rogue survived its masters' death when controlled by Yui. It was weakened by Ryuki's Dragclaw Fire and then destroyed by Knight's Hishou Zan.

- Its name is a portmanteau of three words, psycho, rogue and koorogi, which is cricket in Japanese.
- Its suit's body and legs seem to be the same design as the Buzzstingers', possibly a case of either suit recycling or mold reuse.
