Quetzal is a Mk VII Medium-Chassis Reploid who is a former member of the Repliforce Air Force. Once a respectful soldier, he led a squadron of reploids and mechaniloids into the jungles of South America when maverick mechaniloids began to go haywire in the area and cause ample destruction to the precious rainforests. Unfortunately for Quetzal, Goth himself was behind the infections, and while he fought as best he could, he could not best the Maverick King. As such, he was infected directly by Goth to serve as one of his Maverick Generals. Quetzal was then left to guard the rainforests while Goth sought out greener pastures.
