Monoeyes (モノアイ, Monoeye) are aerial enemies, originating as members of the Underworld Army in the Kid Icarus franchise.
The Monoeye was introduced in the original Kid Icarus as part of the Underworld troops. In Kid Icarus, Monoeyes are found in the Underworld. They fly around in groups of four, impeding Pit's ascension and occasionally swooping down to deal damage on contact. Their behaviors are shared with Micks in the Overworld and Komaytos in Skyworld.
Monoeyes return in Kid Icarus: Uprising as common airborne enemies, appearing in nearly every chapter of the game in both sky battles and land battles. Each Monoeye now possesses the ability to fire a projectile from its eye, which is telegraphed by its iris glowing. Uprising also demonstrates the Monoeye's ability to combine with Mik and Specknose to form a Monomiknose. The Aurum create their own Aurum Monoeye copies, while Cellular Monoeyes are found within Hades's body.
Monoeyes appear as enemies. They fly around, and occasionally stop: their eye starts glowing, and after a short while it shoots a single damaging energy projectile at the player.
