Metalic-Clone

Metal Sonic (メタルソニック Metaru Sonikku?) is a reoccurring antagonist in the Sonic the Hedgehog series. He is an evil Badnik[2] version of Sonic the Hedgehog and undoubtedly Dr. Eggman's greatest robotic creation, built for the sole purpose of destroying his organic counterpart. Deployed during Eggman's operations on Little Planet, Metal Sonic confronted Sonic in battle and lost, though this defeat would not keep him from returning again and again 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 or even surpassing Sonic's.

While mostly serving as Eggman's obedient and quiet enforcer, Metal Sonic is an intelligent machine with a very dark side. He is a cold-hearted, aggressive and ruthless killer with a burning obsession of Sonic that surpass that of his maker's, and his ultimate goal above all else is proving to Sonic that he is the better of them and eliminate him once and for all. His dark quest has made him rebel against Eggman and amass immense power multiple times, only to always fail in the end. To this day though, Metal Sonic has not given up his mission and continues to be one of Sonic's most formidable foes.

Metal Sonic is noteworthy for being the second most recurring villain in the series, only behind Dr. Eggman himself.
