In the first book of Rick Riordan's series "Percy Jackson and the Olympians," titled The Lightening Thief, as daughter of Athena, Annabeth Chase is characterized as intelligent, brave, and a planner.
Athena is the Greek goddess of both war strategy and wisdom, and Annabeth feels she must mirror her mother's attributes. Athena was also a competitor of Poseidon's, god of the sea; therefore, in the beginning of the novel, when Annabeth first meets Percy Jackson, son of Poseidon, Annabeth feels that she must be Percy's competitor as well. However, they soon become devoted friends.
In mirroring her mother, Annabeth displays her intelligence by knowing much about the gods and mythology and being able to answer all of Percy's questions. She is also an excellent strategist, and together, she and Percy escape many tribulations, even managing to sever Medusa's head.
