The Frost Giants, also known as the Jotun, were a race of giants living on the arctic planet Jotunheim. They are also humanoid, but are more Neanderthal-like in body structure. Most stand up to 20 feet tall, but some can reach 30 feet. Giants usually lead a simple type of life, but will war with the gods on occasion because they are jealous of the gods’ superior abilities. Giants have also been known to reproduce half-breeds that look like Asgardians such as Loki.
