Jonathan "Jace" Wayland

[close] "Fighting, hunting, and killing demons are the things Jace is good at. Though the jagged scars and black runic Marks on his body are a badge of honor as far as he's concerned, he keeps a lot to himself. Like the fact that his parents were murdered by Valentine's servants in front of him when he was ten years old. There are a lot of things Jace doesn't talk about — until he meets Clary, a mundane girl who can see him, maybe better than he can see himself. The connection that binds them will force Jace to confront the black secrets of a past he never wanted to remember..."
He struggles throughout the books, having to choose between is father or adoptive family, and has complications on reliazing what is wrong and what is right. He comes across as arrogant, intellgent, and sarcastic, with a messed-up sense of humour. He is a big part of this series, having at least 4 characters that revolve around him.
He may seem independent, but he does depend on those around him, more than he shows, or will ever admit.
