Of all the races of giants, the foremost enemies of the Asgardians are the Frost Giants. They were once ruled by Laufey until he was slain by Odin. His replacement was Urgard-Loki has ruled Jotunheim ever since. The direct descendants of the first giant, Ymir, the Frost giants live in the area of Jotunheim whose climate resembles that of Earth's polar regions. Temperatures in this area never rise above the freezing point of water. The frost giants can exist comfortably at frigid temperatures but are highly vulnerable to heat. Although they can withstand the normal temperatures to be found in Asgard and in the temperate regions of Midgard, intense heat causes them to shrink in size rapidly, as if they were melting. Long exposure to cold will eventually cause them to grow back to their previous size. The Frost Giants' powers are strongest in their own realm of Jotunheim, presumably due at least in part to the frigid climate of much of the realm.
Jack Frost of the Liberty Legion battled with Alies during World War II. His past was a mystery, even to Jack Frost himself. So far as he can recall he has always lived in the arctic.

Powers and Abilities
At least some frost giants have the power to create magical illusions. Utgard-Loki is a master of the sorcery of the frost giants. His powers to create illusions are greater than those of other known frost giants. He can cause the weather of Jotunheim to grow even more frigid. He once transformed Karnilla the Norn Queen into a bird. Utgard-Loki first encountered the Asgardian gods Thor and Loki many centuries ago when the two gods came to his castle. Utgard-Loki demanded that they perform a series of what appeared to be simple feats, which in actuality proved immensely difficult. Using his magical powers of illusion, Utgard-Loki had disguised the objects of the feats that he had Thor and Loki to perform. Hence, in lifting appeared to be a cat's paw, Thor actually was lifting the immense bulk of Jormungand, the Midgard Serpent. Thor and Loki fared impressively in coping with these challenges, despite Utgard-Loki's deceptions.
With some exceptions, like the swordsman Hagen, giants are not highly skilled in the arts of combat, but their sheer size and strength make them formidable opponents even for the Asgardian gods.
Average Strength level
Giants possess superhuman strength and resistance to physical injury. (The flesh and bone of the giants of Jotunheim are about three times denser than similar human tissue, contributing to their superhuman strength and weight.) They are extremely long-lived, but their life spans are not as long as those of the Asgardian gods, who have been able to extend their lives through consumption of the enchanted apples of Idunn.
Heat: When exposed to extreme heat frost giants will start to shrink in size but if they return to the cold climate of Jotunheim they will eventually grow back to their normal size.
Habitat: Jotunheim, the home of the frost giants, is an extremely cold and desolate place.
Type of Government: Tribal
Level of Technology: Giants tend to lead a simple existence as hunters and gatherers.
Cultural Traits: They have a warlike culture, and their envy of the Asgardians has caused them to go to war with Asgard repeatedly over the millennia.
Representatives: See List of Frost Giants
- Frost Giants and Ice Giants are very, very often confused by writers and artists in comics, but are extremely easy to tell apart. The confusion and interchangeability of the two terms are seemingly due to the close relations in the evolution from the Ice Giants to the Frost ones.
