Laistrygonian Giant

Laistrygonian giants are a race of giant cannibals from far north. Odysseus ran across them once in his travels. They are described as being more than eight feet tall with wild eyes, pointy teeth, and hairy arms tattooed with snakes, hula women, and valentine hearts. They appear in Percy Jackson's second adventure and quickly become a common foe in Kronos' army for the rest of the series, though they are never as lethal as when first encountered in The Sea of Monsters.

The Sea of Monsters
A group of Laistrygonians manage to infiltrate Percy's school disguised as visitors from Detroit and join a dodgeball game after being recruited by Percy's new bully Matt Sloan. During the game they transformed and attacked with flaming dodgeballs. Through the help of Tyson and Annabeth, all of them were defeated.
