Frederick Chase

Dr. Frederick Chase is a mortal and is the father of a demigod, Annabeth Chase, and her half brothers, Bobby Chase and Matthew Chase.

History
When Frederick was young, he was a brilliant man who wanted to go to college, but he didn't have any money. His brilliance and wit drew the attention of Athena, the goddess of wisdom. She helped him get into college, and he finished his studies successfully with her help. Their relationship eventually ended on good terms, and Athena sent him their daughter, Annabeth. He was surprised that he had an infant daughter to care for, and tried to get Athena to take her back, but she sternly told him that demigods must be raised by their mortal parent.

Frederick then married an Asian woman and they had two sons: Bobby and Matthew. Dr. Chase's family was frequently attacked by monsters due to Annabeth being a Demigod. Annabeth eventually thought that her mortal family resented her for this, and ran away, eventually running into two other demigods: Thalia and Luke. They had many adventures together until they met Grover Underwood, who took them to Camp Half-Blood. Thalia was dying trying to hold back the monsters following them, but Zeus turned her spirit into a pine tree.

Annabeth eventually returned home at her father's request, but left when she saw that nothing had changed. Her father then sent her his college ring in the hope that she would remember him by it and be convinced to come home. She started to wear his college ring on her necklace with the beads that she earned every year at Camp Half-Blood.

Percy convinced her to try again with her family, and she moved in with them again and settled down in San Francisco.

The Titan's Curse


Annabeth accompanied Percy Jackson and Thalia Grace to assist Grover with two demigods at a military school. Annabeth told Percy that her father was moving to San Francisco but she was unsure whether to go because it was infested with monsters there. Annabeth went missing afterwards and Percy went on a quest to save Lady Artemis to find her.

In San Francisco, Thalia suggested they visit Fredrick Chase for transportation. The revelation of his daughter's disappearance shock Dr. Chase who agreed to give the questers his car which they unintentionally destroyed. After rescuing Artemis, the group were gravely endangered by a fleet of monsters, but Dr. Chase, ignoring the warnings given to stay away, flew in on his plane, a Sopwith Camel. Using special bullets he created out of some of Annabeth's celestial bronze weapons, he shot and destroyed several monsters, ensuring the other's escape.

Dr. Chase was relieved that his daughter was safe and reminded her she still had a home with him before Annabeth left with Percy and Thalia on pegasi.

Personality
Frederick Chase is a fairly normal mortal. However his genius caught the eye of Athena, who was enchanted by his wisdom. He most likely caught her attention by his fascination with wars and his love for airplanes. He loves Annabeth very much, though he did not want her at first, but that is somewhat expected. He didn't know that his friendship with Athena would result in a brain child, and when she came he did not have time to take care of her. Despite this, he has attempted to be on good terms with his daughter. When she ran away at seven, he was heartbroken, until her return several years later. Percy once described Dr. Chase as an "excellent mad scientist" because of his experiment of celestial bullets.

Appearance
Frederick is described as a handsome, athletic, middle-aged man with sandy-colored hair like his daughter Annabeth Chase, with intense brown eyes.

Relationships
Annabeth Chase Frederick's daughter with Athena goddess of wisdom, warfare and crafts. He was surprised that he had an infant daughter to care for, and tried to get Athena to take her back, but she sternly told him that demigods must be raised by their mortal parent. His family was attacked by monsters due to Annabeth being a demigod. Annabeth eventually thought that her mortal family resented her for this, and ran away. In The Titan's Curse, it seems her relationship with them is getting better, and by The Last Olympian she seems to be living with them again (though, this is not for certain because she is going to go to a school in New York near Percy's, and her family lives in San Francisco).

Athena When he was a young, he was a brilliant man who wanted to go to college, but he didn't have any money. His brilliance and wit drew the attention of Athena.
