Zero is the only pup of three that survived when his pack disbanded. The apple of his mother's eye, Zero is doted on by Aster, as well as Crow, the only other remaining member of his previous pack. He's very interested in hunting and begs Crow to take him along, but it's a wonder if he'll ever be able to stray too far from their home, because Aster is too afraid to let her only son see the world.
