These are useful in wolf, shifter, and werewolf RPG games. They can be used to denote the character’s form in your individual RPG posts, or used in character profiles to show your character’s different appearances in each form. RPG admins might want to use differently-colored icons to denote different packs, groups, or species. Or — whatever you want, really! Go wild.
