Hrungnir

Hrungnir (Old Norse: [ˈhruŋɡnez̠], 'brawler') is a jötunn in Norse mythology. He is described as made of stone and is ultimately killed in a duel with the thunder god Thor.

Prior to his demise, Hrungnir engaged in a wager with Odin in which Odin stakes his head on his horse, Sleipnir, being faster than Hrungnir's steed Gullfaxi. During the race, which Sleipnir wins, Hrungnir enters Ásgard, and there becomes drunk and abusive. After they grow weary of him, the gods call on the god Thor to battle Hrungnir. He is slain by Thor's hammer Mjölnir.

Hrungnir is comparable to the Hurrian Ullikummi, a stone-giant who grew so quickly that he reached the heavens. He was slain by the thunder-god Teshub who is equivalent also to the Luwian Tarḫunz and Hittite Tarḫunna.
