Fenrir is a wolf in Norse mythology. Fenrir, together with Hel and the World Serpent, is a child of Loki and giantess Angrboða.
additional information is given about Fenrir, including that, due to the gods' knowledge of prophecies foretelling great trouble from Fenrir and his rapid growth, the gods bound him and as a result Fenrir bit off the right hand of the god Týr.
