Bio: While playing high school basketball in Cleveland, Ohio, Riley picked up the nickname "Downtown" for never missing a foul-shot. Once in the Army, he became skilled enough with firing mortars that he can judge range and trajectory just by eyesight.
Downtown served with the G.I. Joe team on a number of missions before the team was shut down in 1994. He was later called back to join the reinstated Joe team in its battle against the forces of a revived Serpentor on Cobra Island.
After the Joes stopped a plot by Cobra to unleash the weapon known as the Tempest, and defeated a new threat, the Red Shadows, the military again disbanded the team.
One year later, the Joe team was reformed with a smaller roster of active members. Downtown, like most former Joes, is a reserve member of the new team.
