Scourge the Hedgehog

Scourge the Hedgehog (also known as Evil Sonic or Anti Sonic) is a 14 year old hedgehog, and is a villain, and he is found only in the Archie Comics series. As the name suggests, he is an evil double of Sonic the Hedgehog, and thus is an anthropomorphic, humanoid hedgehog. Scourge originally wore a leather jacket, black-rimmed sunglasses, and black leather boots. In order to disguise himself as Sonic, he simply had to remove this clothing and replace it with Sonic's trademark sneakers, though he showed some dislike for the running shoes.

Before draining energy from the Master Emerald, Scourge was an exact duplicate of Sonic, with blue skin and green eyes, but he later transformed so that this color scheme reversed, giving him green skin and blue eyes. Scourge now wears a jacket with flames on the shoulders, black/green shoes and sunglasses with red frames. He also gained two scars (from Locke punching him in anger) across his chest.
