Agent 47 was created by Dr. Ort-Meyer as his 47th clone in his underground cloning laboratory, disguised under the surface appearance of a sanitarium. 47's genetically engineered mind and body makes him the greatest assassin in the world.
After breaking free from the influence of his creators, he found he lacks empathy, and wasn't good for much beyond contract killing. He applied to work for the International Contract Agency (ICA) and outsourced his morality to his hanlder, Diana Burnwood.
Since then, the pair have developed a signature MO. 47 has outsourced his empathy to Diana, who selects targets she considers morally abhorrent. His hits are carried out with artistry and precision, often in the form of freak accidents, with zero collatoral damage. He would remain employed until he exposed ICA agency information to the public, ending them permanently.
Canonically, every single contract carried out by 47 was officially ruled as a freak accident or unsolved mystery. And every contract since his employment in the ICA had zero non-target kills.
47 is a master of disguise, and no matter how absurd the disguise may seem 47 can pull it off with most not suspecting a thing.
