Hyperboreans (Υπερβορείων in Ancient Greek) are giants from the North. They are usually peaceful (according to Thalia) and described as having blue skin and icy gray hair. They appear as enemies in The Last Olympian, but are peaceful during The Son of Neptune.

History

The Hyperboreans were mythical Giants who lived far to the North of Thrace. The Greeks thought that Boreas, the North Wind, lived in Thrace, and that therefore Hyperborea was an unspecified region in the northern lands that lay beyond the North Wind. They are said to be friendly to mortals.

Percy Jackson and the Olympians

The Last Olympian

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 does not want to fight him as he reminds him of Tyson, 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 the Hyperborean giant will bleed blue blood, and when defeated will freeze in a block of ice itself. Percy helped Annabeth 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. Thalia recognizes them, since the Hunters of Artemis met a colony up in Alberta and got into a snowball fight with them.

The Heroes of Olympus

The Son of Neptune

When Percy, Hazel, and Frank 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 hid under one's thighs when the gryphons attacked. The giant blew an ice cold wind which turned the gryphons into "feathery Popsicle sticks".

Trivia

• 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 invisble by The Mist, instead of just appearing in a different form.
