Vidar Slays Fenrir Picture

Vidar was a relatively minor Aesir, despite the fact that in raw strength he was second only to Thor. The God of both silence and vengeance, Vidar spoke little. Instead he spent the majority of his time crafting a giant boot which was made from the cutting scraps of all boots of all time.

In the conflict known as Ragnarok, Vidar would use this colossal boot to stomp upon Fenrir's jaw while hoisting the rest of the giant wolf's head, killing the monstrosity and avenging The All Father Odin.
