|“||A Hyperborean. The giants of the north. It's a bad sign that they sided with Kronos. They're usually peaceful.||”|
Hyperboreans (meaning "beyond the Boreas") are Giants from the North. They are usually peaceful, according to Thalia Grace, and as seen during the events occurring during The Son of Neptune, but appear as enemies in The Last Olympian.
The Hyperboreans were mythical Giants who lived far to the North of Thrace. Boreas, the North Wind, lived in Thrace, and therefore Hyperborean was an unspecified region in the northern lands that lay beyond the North Wind. They are said to be friendly to mortals.
Hyperborean giants are depicted as snow Giants that only serve Kronos due to their extreme gullibility. They fought in the Battle of Manhattan. The Hyperborean giant that accompanied Prometheus wore toy animals around his belt. Percy Jackson did not want to fight him as the giant reminds him of Tyson, and because of his clumsiness. In combat they prove to be quite a threat as they can freeze whatever foes they defeat in a block of ice. When wounded, a Hyperborean giant will bleed blue blood, and when defeated will freeze in a block of ice itself. Percy helped Annabeth Chase defeat a Hyperborean giant which was attacking the campers. He fought several others in the battle and a Hyperborean eventually fought and won a battle with Clarisse La Rue, trapping her in an ice prison until she was rescued and defrosted. Thalia recognized them, since the Hunters of Artemis met a colony up in Alberta and got into a snowball fight with them.
When Percy Jackson, Hazel Levesque, and Frank Zhang arrive in Anchorage, Alaska, they see Hyperboreans wading through the forests, fishing in the bay, and striding through the mountains. Yet these Hyperboreans are peaceful and invisible. They hide under one's thighs when the gryphons attacks. The giant blows an ice cold wind which turns the gryphons into "Feathery Popsicle sticks."
Hyperborean giants are thirty-foot tall giants with blue skin and icy-gray hair.
- They are similar to the frost giants of Norse mythology, though to the Greeks they were more pacified.
- Unlike most Monsters, Hyperboreans are made completely invisible by the Mist, instead of just appearing in a different form.
- They are named after the god Boreas.
- In actual Greek myth, the Hyperborean Giants or Hyperboreades were children of Boreas and Khione - however there were originally only three of them.
- Hyperborean literally means "inhabitant of the extreme north."
- In Greek Myth, the giants are described as 6 cubits in height - which is 108 inches - 9 feet.
