In Norse mythology’s Ragnarok, the hound Garmr fights the god Tyr. Garmr is described as a monstrous canine associated with Hel and the underworld.
In the poetic tradition, Tyr and Garmr kill each other during the final conflict. This detail is sometimes confused with Fenrir’s battle against Odin, because both creatures are huge wolf-like enemies of the gods.
Garmr’s identity is debated. Some scholars and retellings treat Garmr as distinct from Fenrir, while others see overlapping roles between the two mythic hounds. The surviving sources do not provide a single modern-style character biography.
The name appears in Old Norse mythological poetry and prose, especially in discussions of Ragnarok and the realm of the dead.
