look up any word, like pussy:
 
1.
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.

A lycan is NOT a werewolf. The difference between them is that a lycan can transform into a (bigger version) of a wolf when ever it gets the impluse to, it is stronger and usually stays with a pack, of course there have been rare cases when they go off on their own. A werewolf transforms into this stupid half human/wolf thing, unwillingly on a full moon.
lycans are better than werewolves...=]
