commonly mistaken as a werewolf, the Lycan is a more advanced species that, unlike the werewolf, can for the most part control their transformations. A werewolf can only change under the full moon, and cannot control that. The same can be said for lycans, however they are also able to transform at any given time, wether under a full moon or not, should the need arise.
