Metal Sonic - Sonic the Hedgehog

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. 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. 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.
