The Stand-Alone is a pair of Arrowguns that can be wielded by Xigbar in Kingdom Hearts 358/2 Days. It is Xigbar's basic weapon, and therefore requires no Gears to be attached to him in order to wield it. In appearance, Stand-Alone is mostly grey, symbolizing that it is the most basic of all of Xigbar's weapons through the use of achromatic colors.
The body of a Stand-Alone Arrowgun is roughly diamond-shaped with concave edges. It is predominantly white with black edges. The barrel is white, fairly short, and straight with a right triangle-shaped protrusion on its underside. The handle is grey and the black guard is lined by six light grey diamonds, each with black edges. These diamonds flash white when Xigbar reloads his weapons. Its bullets are white, and the sparks they produce are light grey.
The name Stand-Alone refers to the common notion that a brave individual will stand alone in battle, not needing others for support.
The Stand-Alone fires two rounds at a time, one from each Arrowgun. Its ground combo starts with four shots being fired one at a time and ending with Xigbar doing a 360° turn and then firing two slightly larger shots. Its aerial combo starts with four shots being fired one at a time and ending with Xigbar doing a backflip and firing two slightly larger shots at the same time.
