Mono Beetle ( is a recurring enemy in the モノビートル Monobītoru ) ? . It is a mass-produced robot model deployed by the military organization Sonic the Hedgehog series Guardian Units of Nations. It is the most basic model in the Beetle series and its design serve as the template for all the other robots in the Beetle series.
As the Mono Beetles serve as little more than surveillance drones, presumably to support the security functions of G.U.N's bases, they are rather harmless and can occasionally be used as "steps" for
Sonic and Shadow to cross by using Homing Attack.
The original Mono Beetles basically resemble grey balls with blue outlines and armor on the front. On top of them, they have a sharp blue cap with a red-striped edge. Below this cap, reaching from just behind the edge of their front armor to far behind their back, they have a horizontal yellow turbine disk with a red and blue-striped frame. On their "face", they also have a single yellow, red and white lens. In
, the Mono Beetles' design was slightly tweaked, where their lenses were colored more red and white and their cap was emblazoned with GUN's symbol and the number "01".
Shadow the Hedgehog, the Mono Beetles resemble more Bomb Wings. In this game, they are green instead, their dish attachments are made thicker (resembling jet engines) and they have a pair of small wings on the sides.
The Mono Beetle has no method of attack, unlike most other robots in the Beetle series, and will only hover around in the air. When a Mono Beetle espies the player, its "eye" will light up and it will bob up and down excitedly. Sometimes, a Gun Beetle can be invisible to the player can and appear out of nowhere when a character comes near it.
