Annabeth Chase

Annabeth is described to have dark brown skin and a slender, athletic body. She has long braids that are naturally blonde at the bottom Percy said that she "looked like a typical California girl, except that her stormy grey eyes ruined the image." As revealed in The Mark of Athena, she has a belly button despite not being born in the usual way. In the same novel, Aphrodite/Venus noted the beautiful young lady she's grown into.

Despite being taller than Percy originally, Annabeth is now shorter than him, standing at about 5'11 while Percy stands around 6'0. She gains a streak of grey in her hair from the pressure of holding up the sky in The Titan's Curse, but has since lost it by The Mark of Athena. By The Hammer of Thor, Annabeth has started growing out her hair and the way it caught in the sunlight briefly reminded Magnus of Sif.

Annabeth often wears a ponytail, an orange Camp Half-Blood t-shirt, and often wears her magical Yankee cap during fights, since it turns her invisible. She also wears her father's college ring and later a coral pendant that Percy gave her on a leather necklace with the clay beads that she earned every year at Camp Half-Blood. Because she came to camp at age 7, she would have 9 or 10 beads.

When under the effects of Beast Breath, Annabeth's head became that of a barn owl. However, she still had her own demigod thoughts.

Personality Like her mother, Annabeth is an intellectual genius, wise and very witty. Her eyes look calculating, like she is analyzing whoever she is looking at during a first meeting, as if "thinking of the best way to take the person down in a fight". She loves architecture and spends her free time designing new buildings or visiting national monuments. She has a soft side for those who seek knowledge. She sometimes gets too philosophical, which causes the less complicated Percy to glaze his eyes.

Annabeth is very strong-minded and stubborn, shown to be incredibly determined and daring. Much like Percy and Thalia, she has shown many signs of bravery, courage, and dauntlessness. One of her most impressive displays was in The Titan's Curse, where after holding the sky for hours and starting to die, she vehemently protested against Artemis for taking her burden. Even beings like Kronos acknowledged that she is very spirited and understood why Luke wanted to spare her from the destruction.

Though she is very kind-hearted, Annabeth can be very harsh and judgmental during first meetings, but she is very loyal to those who later win her approval. She isn't quick to give up on those she cares about: even after learning Luke was a traitor in The Lightning Thief, she never completely stops caring about him and quickly took the sky from him in The Titan's Curse to save him from death.

According to Sally Jackson, Annabeth is the most level-headed demigod she has ever met. She hardly ever shows her true feelings, often hiding worry or upsetness with raw or teasing anger. When she assumed that Percy was dead in The Battle of the Labyrinth, she said to the crowd "He was probably the bravest friend I ever had", but when he emerged and she figured out that he recuperated on Calypso's island, she said he was "the single most annoying person I've ever met!"
