Scourge the Hedgehog

Scourge (also known as Evil Sonic) is an exact opposite of Sonic, thus, he has all the same traits of Sonic, but he's evil. Scourge has green fur, a leather jacket, black-rimmed sun glasses, and black boots. Originally Scourge had blue fur like Sonic, but in an incident where he tried to drain power from the Master Emerald he changed in color.
