Eradicator

The Eradicator is an artificial construct that assumes a humanoid appearance featured in comic books published by DC Comics. He is associated with the Superman line of comic book titles and first appeared in his most common form in Adventures of Superman #500 in June, 1993. Prior to becoming the Eradicator, he was actually a piece of alien technology that was once a component of a perseveration ship. In this form, it first appeared in Action Comics Annual #2 in May, 1989. He was also featured in his own three-issue limited series, Eradicator, in 1996.

First Sighting
A car-jacker attempted to gun down a would-be victim of his that drove off on him when a mysterious shadowy figure in a cape appearws, warning the car-jacker that he must pay for his crimes. The car-jacker fires on the stranger, hitting only the S-shield on his chest, the only thing visible on the person. The car-jacker fled in fear, but the shadowy caped figure pursued him, striking him with energy bolts that knocked him off a roof and sent him landing in an alley, burned and in pain. The shadowy figure landed, and though he resembled Superman, he was wearing a two-toned Kryptonian bodysuit with a cape attached to his S-shield and a golden visor over his eyes. The figure told his victim that "all who sin shall know the vengeance of Superman."
