Frost Giant (Marvel)

The Frost Giants appeared in 1949 Marvel Comics called Venus. Of all the races of giants, the foremost enemies of the Asgardians were the Frost Giants. They were once ruled by Laufey until he was slain by Odin. His replacement was Urgard-Loki who ruled Jotunheim, until his return. The direct descendants of the first giant, Ymir, the Frost giants live in the area of Jotunheim whose climate resembled 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.
