Some history on Deathstroke, The Terminator:
Slade Wilson was sixteen years old when he first enlisted in the United States Army, having lied about his age. After serving a stint in Korea, he was later assigned to Camp Washington where he had been promoted to the rank of Major. In the early 1960s, he met Captain Adeline Kane who was tasked with training young soldiers in new fighting techniques in anticipation of brewing troubles taking place in Vietnam. Kane was amazed at how skilled Slade was and how quickly he adapted to modern conventions of warfare. She immediately fell in love with him, and realized that he was without a doubt the most able-bodied combatant she had ever encountered. She offered to privately train Slade in guerrilla warfare. In less than a year, Slade mastered every fighting form presented to him and was soon promoted to the rank of Lieutenant Colonel. Six months later, Adeline and he were married and she became pregnant with their first child. The war in Vietnam began to escalate and Slade was shipped overseas. In the war, his unit massacred a village, which sickened him. He was also rescued by SAS member Wintergreen, to whom he would later return the favor.
Chosen for a secret experiment, the Army imbued him with enhanced physical powers in an attempt to create metahuman supersoldiers for the U.S. military. Deathstroke became a mercenary soon after the experiment when he defied orders and rescued his friend Wintergreen, who was sent on a suicide mission by a commanding officer with a grudge. However, Slade kept this career secret from his family, even though his wife was an expert military combat instructor. Indeed, she had been responsible for a significant portion of his early training.
A criminal named the Jackal took his younger son, Jericho, hostage to force Slade to divulge the name of a client who had hired him as an assassin. Slade refused, claiming it was against his personal honor code. He attacked and killed the kidnappers at the rendezvous. Unfortunately, Joseph’s throat was slashed by one of the criminals before Slade could prevent it, destroying Jericho’s vocal cords and rendering him mute.
After taking Joseph to the hospital, Slade’s wife, Adeline, enraged at his endangerment of her son, tried to kill Slade by shooting him, but only managed to destroy his right eye. Afterward, his confidence in his physical abilities was such that he made no secret of his impaired vision, marked by his mask which has a black, featureless half covering his lost eye. Without his mask, Slade wears an eye-patch.
