"Flame." In Gylfaginning, Thor and his companions Loki and Þjálfi travel to Jötunheimr and come upon the hall of Útgarða-Loki. The jötunn says that no one shall be with them who knows not some kind of craft or cunning surpassing most men. Loki claims that none eats his food more quickly he. Útgarða-Loki accepts the challenge and calls upon the giant Logi to try his prowess against Loki:

Then a trough was taken and borne in upon the hall-floor and filled with flesh; Loki sat down at the one end and Logi at the other, and each ate as fast as he could, and they met in the middle of the trough. By that time Loki had eaten all the meat from the bones, but Logi likewise had eaten all the meat, and the bones with it, and the trough too.

Thus Loki is defeated and loses the challenge. It is later revealed by Útgarða-Loki that Logi was in fact "wild-fire" personified.

In Fundinn Noregr and Hversu Noregr byggðist, a figure named Logi appears as the son of Fornjótr, and brother of Hlér and Kári. In Þorsteins saga Víkingssonar Logi's wife is the legendary queen Glöð, who bore him two daughters — Eisa and Eimyrja. He is there also called Hálogi.
