The Emperor Metallix is a giant, red and gold Metallix robot that is the leader of the Brotherhood of Metallix. Unlike other Metallix robots, who have abilities modelled after Sonic the Hedgehog, the Emperor is permanently hardwired into a high-tech throne. The Emperor Metallix uses the throne, which has anti-gravity capabilities, as a transportation device.
Although the original Metallixes had been built by Doctor Robotnik and Grimer, the Emperor Metallix was built by the Metallixes themselves in Robotnik's abandoned Egg Fortress, which had been set to run on automatic. The Metallixes had been charged with creating the ultimate badnik version of Sonic, but when the Emperor was created he developed plans and goals for the Brotherhood of Metallix that were independent of Robotnik.
- The Emperor Metallix is loosely based on Metal Sonic Kai, the final boss of the game Knuckles' Chaotix. In that game, Metal Sonic transformed into a large red version of itself by means of the Chaos Rings, but was defeated by Chaotix.
- However, the Emperor Metallix in Sonic the Comic also shares similarities with the various Dalek Emperors from the TV series Doctor Who. Writer Nigel Kitching has admitted the similarity. According to Kitching, while he had not initially intended to rip off the Daleks, when he noticed the similarity he decided merely to run with the idea, rather than tweak it into something different. At the time, Doctor Who had been off the air for seven years, and Kitching felt that the similarity was unlikely to jar with the readership.
