Metal Sonic - Sonic the Hedgehog

General Summary: Eggman's obedient and silent enforcer, Metal Sonic.

Metal Sonic is a major antagonist that appears in the Sonic the Hedgehog series. He is an evil, ultra-high performance, very advanced Badnik version of Sonic the Hedgehog that was created as a weapon by Dr. Eggman for the sole purpose of destroying the hedgehog. Modeled with extreme accuracy after Sonic, Metal Sonic not only resembles his template, but can also imitate his moves and achieve speeds matching and even exceeding the hedgehog's own.

Physical Descriptor: Metal Sonic was created in the image of Sonic the Hedgehog and is thus mostly built of blue metal. He has a yellow circular depression in his chest with a black center, mirroring the peach skin on Sonic's chest. His head has metal fins resembling Sonic's quills and a pair of triangular "ears." Metal Sonic has a muzzle, shoulder plates, upper arms, legs, and fingers made out of silvery metal. His palms are black, while the backs of his hands are square yellow plates.

His forearms and lower legs are blue metal like his head and torso, and he has red feet with white stripes designed to resemble Sonic's shoes. To simulate the hedgehog's eyes, he has monitors with cameras behind them, giving them a red iris and black sclera look.

Personality: Metal Sonic is the exact opposite of his organic counterpart in terms of personality. Metal Sonic is a cold, dark, aggressive, mysterious and outwardly emotionless machine. Early on though, he had a habit of mimicking Sonic's gestures, perhaps in a mocking manner. Notably, Metal Sonic is predominantly mute.

Metal Sonic is Dr. Eggman's docile and completely obedient enforcer. Although he serves Eggman, Metal Sonic carries only one goal in mind: destroy Sonic using abilities superior to his. However, he is far from being another mindless Badnik. In fact, Metal Sonic is an intelligent and calculative machine thanks to an AI chip given to him by Eggman.

While usually serving as Eggman's obedient and silent enforcer, Metal Sonic is an intelligent robot with a very dark side. A cold-hearted, aggressive, and ruthless killer, he is obsessed with proving his superiority to Sonic and eliminating him for good to the point where he has rebelled against Eggman more than once to achieve his goal.

Speech pattern-wise, sometimes he switches to normal English from robot speech.

Background History: First deployed during the Little Planet incident, Metal Sonic confronted Sonic in battle and lost, though he would repeatedly return to challenge Sonic and his allies as Eggman's "too-sharp sword".

However, he always fails in the end, only to later return more powerful than before. To this day, Metal Sonic remains one of Sonic's most dangerous foes. Despite his many defeats and having his beliefs shaken though, Metal Sonic never gives up and will always pursue his goals with relentless determination and take any means necessary to achieve them.
