History
Gray Wolf was a retired CIA Agent and had been diagnosed with cancer. He would be told that he had six months to two years to live. When Gary Hampton went on his first full moon frenzy, he would attack an old man, who would be Gray Wolf, believing that he had killed him. However, Gary attacking him would turn him into a werewolf and cure his cancer. Soon after, he would be found by Cecil Stedman and given a purpose to fight for the Global Defense Agency [1]
