Víðarr (Old Norse: "the wide ruling one") is the god of vengeance in Norse mythology. A member of the Æsir, he is the son of Odin and the giantess Gríðr. During Ragnarök, when the monstrous wolf Fenrir swallows Odin whole, Víðarr is told to avenge his father's death, as he takes Fenrir by the jaw and tears his head apart, killing Fenrir. He will ultimately survive Ragnarök, as he will then meet with his brother Váli in Iðavöllr, where Asgard once lay; there they are joined by their brothers, Höðr and Baldr, as well as Thor's sons, Magni and Móði. After Ragnarok Víðarr will rule after Odin.
