Seen as narcissistic, gorgeous, determined and an expert Shadowhunter, Jace is a natural-born leader and is Alec's second-in-command whenever on assignments with him and Isabelle. Jace is headstrong and often prefers to act first and ask permission later. Tough, resourceful, and confident, Jace takes slaying demons in his stride, often admiring himself while he does so.[48]

He is incredibly loyal to his allies and will stop at nothing to help and save them when necessary. Jace is prepared to risk his life and standing with the Clave to protect others, easily doing so to prevent harm to others. As the adoptive son of Maryse and Robert, he has a fierce love for his adoptive family, especially his adoptive siblings Alec and Isabelle, whom he can be quite protective of.

Like most of his kind, Jace was raised to view love and feelings as a distraction from their sacred mission, though he was not completely averse to it either, specifically after Clary's presence and influence.

Jace is usually sarcastic and humorous. He is also incredibly stubborn, as seen with his recurring arguments with Alec. He can be impatient and easily annoyed when things are not moving forward, or when his skill is called into question. Beneath the humor lies a darker side, one where Jace has always felt like an outsider and was further driven to believe he was tainted after Valentine's lie. He is prone to excessive drinking and indulging in sex to distract himself from more negative emotions, preferring those outlets to talking about his feelings with someone.
