Nox (Wakfu)

Nox is the main antagonist from Season 1 of the French anime, Wakfu, which is based on the game of the same name. He desires to take all of the Wakfu from the world, or atleast enough of it, to power the Eliacube, a small cube of incredible power that appears to speak to him, and go back in time to save his family from death. Because he is trying to go back in time, he is ruthless in the pursuit of his goal and takes many lives in his quest to gather Wakfu (life force/energy), as he believes that when he goes back in time, all that he has done will be undone.
