Jason is 18 years old. Black hair. Blue eyes. Many scars on his face and body and a "J" scar on his  left cheek. Tall, a bit emaciated.

Difficult, broken, angry. Violent. Nightmares, abandonment issues. Severe trauma, PTSD. Hates Sir Bruce Wayne. Protective. Anti-hero. Has no qualms with killing. Needs affection. Touch starved.

He's just escaped confinement after two years at the hands of a deranged sorcerer. He's half-feral. A dark presence gave him an ornate knife. Weak to kindness.
