Scourge the hedgehog is the complete opposite of sonic the hedgehog. He's a cocky, arrogant person who doesn't take anything from anyone, he's selfish and downright evil (Being a copy of sonic and all) I'd like to mention that in terms of origin he is from the Archie Sonic comic books.

For a better understanding of the character, I will link some videos of a fandub too get a better picture of the character
