Hrungnir

[3] They have a short verbal exchange about the quality of their respective horse, during which Odin states his willingness to bet his head (his life) on the result.

[5] Hrungnir becomes so intoxicated that he threatens to remove "Val-hall and take it to Giantland" and to "bury Asgard and kill all the gods", besides the beautiful goddesses Freyja and Sif whom he intends to keep for himself.

[1][3] Thor arrives at the appointment with his servant Þjálfi, and Hrungnir is escorted by Mokkurkálfi ('Mist-calf'), a mighty creature made of clay, and with the heart of a mare.

But the giant Mokkurkálfi is said to be "quite terrified" and he "wets himself" at the sight of Thor, whereas Hrungnir, whose heart, head and shield appear to be made of stone, is "standing unguardedly".

Haustlöng (Autumn-long, 14–20), a poem written by the early 10th-century skald Þjóðólfr of Hvinir and from which Snorri claims to derive his own account, depicts Thor's journey to the duel while the cosmological elements are reacting: the "ground all low" (earth) is "battered with hail" and "all the hawk's sanctuaries" (the skies) are in flame; "Svolnir’s widow" (Odin's consort, Jörð [Earth]) practically split apart".

[3] Baldr’s brother [Thor] did not spare there the greedy enemy of men [Hrungnir], Mountains shook and rocks smashed; heaven above burned.

I have heard that the watcher [Hrungnir] of the dark bone [rock] of the land [sea] of Haki’s carriages [ships] moved violently in opposition when he saw his warlike slayer.

The rock-gentleman [giant] did not have to wait long after that for a swift blow from the tough multitude-smashing friend [Thor] of hammer-face-troll [Miollnir].
