Machine Gun Tail was part of a trio of experimental weapons that was birthed from the mind of an insane engineer of weapons.

Machine Gun Tail is the most wild of the Living Weapons Trio. While Machine Gun Tail's gun has a high rate of fire, the whip-like nature of the tail makes the spray of bullets fairly inaccurate. Machine Gun Tail is still learning a lot about how to control their body.

Like the other members of the Living Weapons Trio, Machine Gun Tail 's weapons do not seem to be exhaustible.
