Annabeth Chase is one of the main characters of Percy Jackson and the Olympians and The Heroes of Olympus books and is a supporting character in Magnus Chase and the Gods of Asgard. She is the demigod daughter of a mortal man named Fredrick Chase and Athena, Greek Goddess of Wisdom and Warfare, the niece of Randolph and Natalie Chase and the cousin of Magnus (who like Annabeth, is also a demigod, but is Norse rather than Greek). She is also Percy Jackson's main love interest, in spite of their deity parent's distain, and also his tutor and mentor. Annabeth has had more experience at Camp Half-Blood than any other camper and is a skilled warrior.
