Jason is 18-19 years old. Black hair. Blue eyes. Multiple scars on his face and body and a "J" brand on his  left cheek. Malnourished from his torture. Wounded. Weak.

Once a difficult, angry kid with temper issues due to his parents' abuse. Was headstrong, smart, and a great athlete. Loved being a hero. Broken by Joker's torture, Jason has lost some of his edge. Nightmares and abandonment issues. Severe trauma and PTSD. Hates Bruce. Slowly comes to trust his savior. Still brave. Still a hero.
