The Gun Wing (ガンウイング Gan'uingu?) is a robot deployed by the military organization Guardian Units of Nations, and a part of the Beetle series. It is essentially a modified version of the Gun Beetle. It appeared as an enemy in Sonic Adventure 2 and Sonic Adventure 2: Battle.
The Gun Wing heavily resembles a Gun Beetle, though with a few differences. While it possesses the same main body, cap and gun attachment like the Gun Beetle, it has twin engines set on each side and wings set on each side of the engines.
The Gun Wing attacks by strafing, firing projectiles while passing by in a fixed trajectory. When destroyed, the Gun Wings each grant the player five hundred points. A key difference between the Gun Wing and the Gun Beetle is that the Gun Wing can move around inside stages, unlike the Gun Beetle which remains in one spot.
