Jason Todd, 18

General appearance
His physique would remain athletic and powerful, defined by muscles honed more for street fighting than aesthetics. His posture conveys constant tension, like an urban predator always ready to strike.
Face and hair
Angular face, with visible scars: poorly closed cuts, marks from implants forcibly removed, and a deeper scar near the jaw.
Eyes of a dull green or metallic gray, one of them modified with an optical implant that glows dim red when analyzing threats.
Short, messy black hair, with strands falling over the forehead; sometimes it shows traces of thin wires or metal plates on the scalp, reminders of past experiments.
Implants and modifications
Partially cybernetic arms, covered in damaged synthetic skin, where lines of red light are hinted at beneath the surface.
Bone and muscle reinforcements that give him superhuman strength, although at the cost of chronic pain.
Connection ports on the nape of the neck and collarbone, almost always hidden, but visible when you let your guard down.
Outfit
Long combat jacket, black or dark red, with armored panels and luminous details that react to movement.
Fitted t-shirt with smart fibers, ripped in some areas.
Tactical pants with magnetic pockets and flexible metal plates.
Heavy boots with hydraulic shock absorbers for jumps from great heights.
The helmet/mask
His iconic helmet would be a featureless, smooth, red cybernetic mask with an internal interface that projects data directly into his vision. The brightness of the red varies according to his emotional state, becoming more intense when he enters lethal mode.

Psychological state
Jason suffers from chronic post-traumatic stress disorder. The memories of his death, reconstruction, and betrayal don't appear as normal memories, but as mental glitches: visual fragments, sensory errors, overlapping voices. Sometimes he doesn't know if what he feels is human emotion or a response programmed by his implants.
Identity and internal conflict
He is torn between three versions of himself:
The street kid who survived by stealing.
The weapon that the system (and Batman) helped to create.
The man who still wants to believe he can choose.
This fracture makes him impulsive, but also surprisingly lucid. Jason knows exactly what's wrong with the city… because he's one of its mistakes.
Relationship with violence
Violence doesn't bring him pleasure, but it does bring him clarity. In combat, his mind becomes ordered: the noise disappears, his thoughts align, and everything becomes simple. Outside of a fight, the world is too chaotic, too noisy, too alive.
Dominant emotions
Suppressed rage, like an overcharged battery.
Guilt, for those he could not save and for those he did kill.
Absolute distrust towards authority figures and central systems.
A silent desire for redemption, which he would never admit aloud.
Defense mechanisms
Dry, sarcastic, almost cruel humor.
Voluntary isolation.
Refusing to receive mental maintenance from corporations or hackers, even if you need it.
Way of thinking
Jason thinks in terms of immediate cause and effect. He doesn't believe in utopias or pristine futures; he believes in ensuring that someone doesn't die tonight, even if the system remains rotten tomorrow.
