Loki

"How interesting. I have my servant here. His name is, amusingly enough, Logi. Would you like an eating competition with him?"

Utgardaloki clapped his hands, and a long wooden trough was brought in, with all manner of roasted animals in it: geese and oxen and sheep, goats and rabbits and deer. When he clapped his hands again, Loki began to eat, starting at the far end of the trough and working his way inward. He at hard, he ate single-mindedly, he ate as if he had only one goal in life: to eat all he could as fast as he could. His hands and mouth were a blur.
Logi and Loki met at the middle of the table.

"Of course it was. Have you ever seen wildfire come down a valley, burning everything in its path? You think you can eat fast? You will never eat as fast as Logi, for Logi is fire incarante, and he devoured the good and wooden trough it in as well by burning it. I have never seen anyone eat as quickly as you."
