Metallix the Metal Sonic was built as a part of Robotnik’s “Operation: Terminate Sonic”. While the Egg Fortress was on autopilot creating Metallix’s of the Sonic Team and Sonic himself, the Emperor came to power. As of now, his lieutenants are Silver Sonic, Mecha Sonic, NEO Metal Sonic, Metal Sonic and Mecha Sally. He commands the Brotherhood of Metallix, a faction made up of Metallix’s, and the Mecha and Metal Series robots created. With the Alpha Device, he conquered the Miracle Planet.
