Fenris
The great wolf of Norse myth, another of Loki's children.
Fenris (Fenrir) is the giant wolf of Norse myth, son of Loki. The gods feared how fast he grew, and in the old tales they bound him, leaving him tied until the end of the world.
In our stories he is a hungry, loving wolf puppy who eats everything and wants only to play. He is not bound.
