Metal Sonic Trooper

Metal Sonic Troopers are an army of Metal Sonic automatons designed and created by Sir Charles Hedgehog and Rotor Walrus to help defend Knothole from the likes of Dr. Eggman when Sonic was believed to be dead after the Xorda's attack on Mobius, before they were hacked by A.D.A.M and later destroyed. They would later be reintroduced in 3238 during the Naugus Resurgence with an improved CPU, courtesy of the Zarvok Federations to help improve the Royal Army's fighting force.
