Fenris, Fenrir (Scandinavian, Icelandic) The mythical Norse wolf destined to devour the sun at the end of its lifetime. Fenris is one of the three monstrous offspring of Loki, the other two being Hel, queen of the realms of death, and Iormungandr, the serpent that encircles the earth in the ocean's depths.
According to popular tale, Fenris grew so rapidly that the gods became alarmed lest he devour the sun prematurely and tried repeatedly to restrain him with heavy chains with no success. The dwarfs forged a magic thread, Gleipnir (lissom bond), with which the gods bound the wolf, but only when one of the gods, Tyr (Mars), agreed to hold his hand in its jaws. Tyr sacrificed his hand, so that Fenris would be harmless until the end of the cycle.

A dangerous werewolf who tries to bite and contaminate as many people as possible.
