Percy Jackson and the Olympians: Legends

Katie has brown hair with pigtails, freckles, and green eyes.

Katie is very kind and patient, yet passionate and willing to risk her life for the gods. Katie is said to remind Percy of her mother Demeter, by her bossiness and the way she argues. She dislikes the Stoll brothers (Connor and Travis) because they put chocolate Easter bunnies on her cabin's grass roof. As her mother is Demeter, the goddess of Agriculture, she would have liked gardening and nature. She is shown to be stern with others, a trait she inherited from her mother.

Katie Gardner is a Greek demigod daughter of Demeter, and the former Head Counselor of her cabin. During the Battle of Manhattan, Katie rode on the strawberry trucks along with the rest of the campers from Camp Half-Blood to the Empire State Building, and prepared to defend the city. During the battle she was ordered by Percy Jackson to take her cabin and defend the Brooklyn Battery Tunnel. It was said that they "turned it into a jungle." Later on when the fighting got closer to the Empire State Building, she was heard yelling to hold their lines. After the Battle of Manhattan, Katie reported to Percy when he came down from Olympus that she saw Rachel Elizabeth Dare leaving the Empire State Building unharmed, before taking Blackjack back to Camp Half-Blood.
