Number 11 is not a human being, but a carefully crafted weapon. Born in a dark laboratory in Romania, he is the perfect killer synthesized by geneticist Ot Meyer using the DNA of five criminals - bald, cold, and with a barcode symbolizing the product code branded on the back of his neck. He was supposed to be an emotionless killing machine, but he awakened to self-awareness during a mission and discovered that he was nothing but a puppet of the global conspiracy organization "Providence".
