Werewolf+Fangs
The extension of fangs, is one of the first steps in a shapeshift for a werewolf. The fangs can be used as a werewolf's last resort defense mechanism as in Raving, Derek Hale bites Victoria Argent to disarm her during his faceoff with her when saving Scott's life.
The fangs are most commonly used by alphas to transform a human into a new werewolf through the Bite or to wound other were-creatures and hinder their healing.
