Nox

Nox is the main antagonist from Season 1 of the French anime, Wafku, which is based on a 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 immense power that he believes speaks to him, to go back in time and save his family from death. Because he is trying to go back in time, he has no qualms over the lives he destroys in his search for wakfu, as he believes that when he goes back in time, all that he has done will be undone.
