There's an interesting story behind Teen Wolf's McCall Pack Symbol. The 2011 fantasy series starred Tyler Posey as Scott McCall, a teenager turned werewolf due to an animal bite he got in the woods. Scott forms the McCall Pack, which includes other werewolves and supernatural creatures. Other than werewolves, the pack also includes a banshee, a thunder kitsune, a werecoyote, and even humans. Each member of the pack has unique characteristics which make them such a powerful and unstoppable group. One quality they share is a special symbol called the McCall Pack symbol, which Scott has tattooed on his bicep.
