Scourge the Hedgehog and Sonic the Hedgehog are not related in the traditional sense of being family members. Scourge is actually an evil doppelganger of Sonic from a parallel universe in the Sonic the Hedgehog comic series by Archie Comics. Their connection lies in their physical resemblance and similar abilities, but they are distinct characters with different personalities and motivations.
