*Plaguesong is dead and this incarnation of him is a ghost.
*Although he is a ghost, he can make his body "real" for a few hours every once in a while, but becomes incredibly weak and tired after he returns to his ghost form.
*He is constantly bleeding and his paws are always covered in blood.
*The necklace around his neck is mandatory, it is the only thing that can tie him to this world, so it needs to be drawn on.
*Bullet wounds go straight through, and are perfectly symmetrical
