The Perfectionist

Hanzō Ueda is a former hitman turned vigilante.

Hanzō is a World War 2 survivor who was cryogenically frozen for 84 years. Hanzō woke up in the year 2030, so an unknown company could do experiments on him. Hanzō was turned into a drug addict, specifically a drug which enhances all of his senses, and makes him stronger than the peak human. Hanzō took on the alias Perfectionist because of his MO.

As the name suggests, Perfectionist is well, a perfectionist. He leaves no clues behind, and doesn't hesitate with killing his targets.

Abilities
Hanzō's hearing is enhanced to the point where he can hear heartbeats, tell if people are lying, locate them through darkness and smoke. His vision is enhanced, along with his stamina and agility.

Hanzō reacts less to pain when on the drug, and has better regenerative abilities; with enough time, he could heal any non-fatal wound.

After severe use of the drug, Hanzō cannot die of old age.

Hanzō altered the original serum to create different variations which give him varying abilities.

Previously, he's used a serum which is completely based on regeneration, one which keeps everything however favors strength, etc.

Gear
Hanzō wears a dark blue suit, with a red tie and an unusually perfectly ironed white shirt. He acquired a bulletproof suit from ZION, later combining it with his own for extra protection.

He has a wide arsenal of weapons, from pistols to rocket launchers. Most of the time, Hanzō has a pistol or two handy, interchangeable with explosive ammo.

Hanzō keeps many syringes with the serum handy, incase he ever runs out, along with a combat knife.
