Ocelot was born Adamska during the Allied invasion of Normandy, France, on June 6, 1944.
After making a full recovery another three months later, she speculated that her body had willed her to live for the sake of her unborn child. Although her unborn child was saved from the bullet, The Joy entered a coma for three months before regaining consciousness. The Joy learned of her pregnancy during a secret mission, which resulted in her blowing her cover and being injured by enemy gunfire. Ocelot was conceived in late 1943 by The Joy and The Sorrow, an American and Russian soldier, respectively, of the Allied Forces' Cobra Unit.
