Loki

Odin will battle Fenrir bravely, but the wolf is more vast and more dangerous than anything could possibly be. It is bigger than the sun, bigger than the moon. Odin thrusts into its mouth with his spear, but one snap of Fenrir's jaws, and the spear is gone. Another bite and a crunch and a swallow and Odin, the all-father, greatest and wisest of all the gods, is gone as well, never to be seen again.
