Pyro Scourge

Scourge the Hedgehog (from the Archie Comics) escapes from a prison zone and enters into Skid's world. While there, he tries to steal the red fire crysal. Skid catches him in the act and the two fight. Scourge's glasses and jacket are shredded in the process. Scourge is able to get past Skid at one point and obsorbs some of the crystal's power, turning him red, creating black stripes on his quills and forming a symbol on his forhead. The scars on his chest are also healed.

(There is more but I'll just leave with the basic of what happened to Scourge to make him look like this)
