Revolver Ocelet, whose real name is Adamska, was born on D-Day (June 6, 1944) to The Joy and The Sorrow, soldiers of the elite COBRA unit. He would work as a code breaker for the NSA, before serving under Volgin’s command, while being a spy for the KGB and CIA at the same time. He would participate in Operation Snake Eater, working for both Volgin and assisting Naked Snake (Big Boss).
He was one of the founding members of The Patriots, along with Big Boss and a few others, an organization that was going to be similar to the American Philosophers. Eventually, Ocelot would make contact with Miller and the survivors of the MSF, helping to protect Big Boss from Cipher. He used revolvers as his choice of weapons, as he considered them the greatest handgun ever made.
