Yes, wolf shifters, use an ancient form native american magic to transform themselves into wolves, much like Skinwalkers.

Werewolf/ Wolfman changes at night into a bipedal killing machine , and when there is a full moon, they are the most powerful, can't  be hurt, but they go into a killing frenzy.
