Agent 47 (also known as "The Hitman" and "47," among many pseudonyms like "Tobias Rieper") is the main protagonist of the Hitman series. He is a professional hitman and top assassin for the ICA (International Contract Agency). His genetically engineered mind and body make competition next to nothing, and for this reason, Agent 47 is considered to be the greatest (and not to mention, most discreet) assassin in the world.
