Though Reyes led the strike team, Morrison was recognized as the team's moral fabric. When the Omnic Crisis began and the UN began to assemble Overwatch, the two accepted the offer to join alongside Reinhardt Wilhelm, Torbjörn Lindholm, Ana Amari, and Liao. Born in Los Angeles, Reyes was enlisted into the US's Soldier Enhancement Program as Soldier: 24, and through it formed a close bond with Jack Morrison. Gabriel Reyes was a senior officer in the US military. They believe that Reaper is hunting former Overwatch agents and systematically eliminating them. Those attempting to track his movements have begun to see a pattern in his appearances. It is possible that he is a byproduct of failed genetic alteration which forces his cells to simultaneously decay and regenerate at a hyper-accelerated rate. The few bodies recovered of those he kills are pale, empty husks drained of life, their cells showing signs of intense degradation. Survivors have described a black shadow ghosting unscathed through the most hellish battlefields. He has fought in many armed conflicts in the last decades, showing no loyalty to any cause or organization. The Reaper is an extremely volatile mercenary, a ruthless and remorseless killer responsible for terrorist attacks across the world. What is known is that where he appears, death follows.
Some speak of a black-robed terrorist known only as the Reaper.
