In Norse mythology, Geri and Freki (Old Norse, both meaning \"the ravenous\" or \"greedy one\") are two wolves which are said to accompany the god Odin. They are attested in the Poetic Edda, a collection of epic poetry compiled in the 13th century from earlier traditional sources, in the Prose Edda, written in the 13th century by Snorri Sturluson, and in the poetry of skalds. The pair has been compared to similar figures found in Greek, Roman and Vedic mythology, and may also be connected to beliefs surrounding the Germanic \"wolf-warrior bands\", the Úlfhéðnar.

In Norse mythology, Fenrir (Old Norse: \"fen-dweller\"),[1] Fenrisúlfr (Old Norse: \"Fenris wolf\"),[2] Hróðvitnir (Old Norse: \"fame-wolf\"),[3] or Vánagandr (Old Norse: \"the monster of the river Ván\")[4] is a monstrous wolf. Fenrir is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda and Heimskringla, written in the 13th century by Snorri Sturluson. In both the Poetic Edda and Prose Edda, Fenrir is the father of the wolves Sköll and Hati Hróðvitnisson, is a son of Loki, and is foretold to kill the god Odin during the events of Ragnarök, but will in turn be killed by Odin\'s son Víðarr.
