Metal Sonic (メタルソニック) is the secondary antagonist in the Sonic the Hedgehog series. He is an evil Badnik version of Sonic the Hedgehog and undoubtedly Dr. Eggman's greatest creation, built for the sole purpose of destroying Sonic. Deployed during Eggman's operations on Little Planet, Metal Sonic confronted Sonic in battle and lost, though he would repeatedly return to challenge Sonic and his allies. Modeled with extreme accuracy after Sonic, Metal Sonic not only resembles his template, but can also imitate his moves and achieve velocities matching Sonic's. While mostly serving as Eggman's obedient and quiet enforcer, Metal Sonic is an intelligent machine 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.


Adventures of Sonic the Hedgehog

In this series, he was known as Pseudo Sonic. He was built by Robotnik to frame Sonic for numerous acts of hooliganism. Pseudo Sonic was not a sentient Badnik in the cartoon, but a mindless mech piloted by a mouse named Lawrence, one of Robotnik's captives.

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, and 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. He has optic sensors with black sclera and red irises.
