Hailstrum

Hailstrum is a Frost Giant.

Thor
Hailstrum is a Frost Giant, a member of Laufey's army and easily one of the largest and strongest of his kind. He fights with Thor when he arrives along with Loki, Sif and the Warriors Three to invade Jotunheim, and manages to to briefly keep The God of Thunder off balance using his size and strength. However Thor eventually throws Mjolnir at Hailstrum, which crushes the Frost Giant's skull, killing him instantly.
