Clary Fray

Clary turns 18 and gets into an art program. That same night, at Pandemonium, she sees Shadowhunters fighting demons. Jocelyn tries to tell her the truth and is taken by Valentine's men. With Jace, Alec and Isabelle, Clary learns about runes and finds out Magnus Bane wiped her memories at her mother's request.

To save Jace, she gives up her own memories to a memory demon. She learns Valentine is her father, and he claims Jace is his son too. At the end of S1, Hodge hands the Mortal Cup to Valentine, but the group manages to wake Jocelyn with a spell.

Clary learns to create runes nobody has seen before. Her mother's return doesn't last: Jocelyn is killed by a demon-possessed Alec. Desperate, Clary makes a dark-magic bargain with the warlock Iris Rouse to bring her back, then breaks it. She dates Simon for a while, until the Seelie Queen forces her to kiss Jace and the relationship ends.

Jace learns they aren't blood siblings. Sebastian, the charming newcomer at the Institute, turns out to be Jonathan, Clary's real brother. At Lake Lyn, which is the Mortal Mirror, Clary kills Valentine. Jace dies in the battle, and she uses the wish granted by the angel Raziel to bring him back.

The Clave sentences Clary to death, and a ritual of Lilith's binds her to Jonathan with a rune: whatever hurts one hurts the other. She disappears with her brother and spends time under his influence, until Jace breaks the bond with the sword Glorious.

In the end, Clary uses a forbidden rune to defeat Jonathan, defying Raziel. The punishment comes fast: she loses her runes, the Sight and every memory of the Shadow World, and leaves the Institute. A year later, at an art show, Clary sees Jace through his glamour and reaches for the runes at his collar.

In the 2013 movie, Clary (Lily Collins) keeps drawing a strange symbol and watches Jace kill a demon at a club. Her mother vanishes after mentioning Valentine. At the Institute, Clary learns she's a Shadowhunter and that Magnus Bane blocked her memories. She hides the Mortal Cup inside a tarot card, but Hodge hands it over to Valentine, who claims to be her father. Clary fools Valentine with a fake Cup and pushes him through a portal.

In Cassandra Clare's books, Clary is turning 16 as the story starts; the show made her 18. Clare says studios asked her to swap her heroine for a boy, and she refused. Katherine McNamara plays Clary on the show; Lily Collins played her in the movie.
