The Fenris wolf (also Fenrir, Fenrisúlfr) is a son of the evil god Loki and the giantess Angurboda. Until finally, at the twilight of the gods, Fenris breaks his chains and devours Odin. Odin's son Widar will kill Fenris, but it will all be too late, the Allfather of the Gods will fall and, with him, the order of the world.
