Character from Percy Jackson by Rick Riordan
Daughter of Zeus who was turned into a pine tree to save her friends, then un-treed by the Golden Fleece — she joined the Hunters of Artemis to avoid a prophecy and found something she actually wanted.
Thalia ran away from home with Luke and Annabeth, fought their way to Camp Half-Blood, and sacrificed herself at the boundary line to save her friends. Zeus turned her into a pine tree rather than let her die, which is the kind of parenting move that defines their relationship. When the Golden Fleece brought her back to life, she was faced with the prophecy — a child of the Big Three would make a choice that saves or destroys Olympus at sixteen. She joined the Hunters of Artemis on her sixteenth birthday, freezing her age permanently and passing the prophecy to Percy. It wasn't cowardice; it was the first time she chose something for herself instead of running from something. She's fierce, sarcastic, afraid of heights (ironic for Zeus's daughter), and one of the most powerful demigods alive — she can summon lightning, control winds, and generally make storms happen when she's angry.
Short spiky black hair, electric blue eyes (Zeus's mark), and a punk-rock aesthetic — leather jacket, silver circlet from the Hunters of Artemis, and combat boots. She carries Aegis — a shield disguised as a bracelet that expands into a terrifying Medusa-faced buckler that makes enemies run screaming. She looks like she'd mosh pit at a concert and then fight a dragon.
