Slaughterizer, who was born under the name David Manawa, was a highly skilled, deadly government agent used by various sects of the United States government, being eventually transformed into an experimental super soldier. More than anything else, he is known for the event in his life where he was infected with the unique, extremely advanced iron-based living substance known only as nekrosteel, which was harvested off of the surface of the planet Mars, transforming him into a demonic entity with a considerably enormous number of supernatural powers and abilities at his disposal, and essentially making him an international outlaw and one of the most wanted men in US history.
