Although inspired by the lore and legend of the American Old West, Revolver Ocelot is a product of the former Soviet Union. With the fall of the Russian empire, Revolver Ocelot left his police unit to join the KGB's special forces. This proved to be an uneasy fit, as Ocelot's independence and unique style of combat put him at odds with his superiors. Knowing he needed a change, Ocelot jumped at the chance to join Foxhound when it was offered to him.

The origin of Revolver Ocelot's obsession with the American West is unknown, but manifests itself in both his appearance and fighting style. He prefers the long duster and antique suit of this bygone era, and his favorite weapon is the Colt Single Action Army Revolver, a gun produced in the 1860s. He enjoys the challenge of having to reload during battle... an opportunity afforded him by his amazing accuracy with the firearm.
