The Sonic characters are wolfs in this story. Shadow's family was hunting with his pack as everything began. They almost got their prey as gun shots were heard and Shadow's mother fell motionless to the ground and the hunting began. Shadow was the only one of his pack who had survived the attack and was now a lonely wolf who was roaming through the forest until he came across another pack. The Sonic characters belong to SEGA, also the pic doesn't belong to me (got it from the Web).
