Annabeth Chase
She first meets Percy Jackson after he was attacked by the Minotaur and makes his way into Half-Blood Hill. When he first saw her, Percy described Annabeth as "pretty" with blond hair curled "like a princess"  After Percy heals from the Minotaur attack, Annabeth hears that he is to go on a quest (search) and she wants to go along, thinking Percy is "the one" from The Great Prophecy. Together, she, Percy, and Grover go searching for Zeus's stolen lightning bolt. Throughout the book, Annabeth shows her unique intelligence, which she inherited from her mother, and also her arachnophobia (fear of spiders) that she shares with all her siblings on her mother's side (originating from the story of Arachne and Athena)
