Cauldron's history is tied to a man name Kevin Crow, who was a member of the special forces for Cadmus. He was one of the elite flying units sent to provide backup for Superman in his battle against Doomsday. Crow was badly injured during the battle, losing his right eye and the use of his legs. Crow volunteered for an experiment at Cadmus, where a cybernetically enhanced clone of Crow was created. The clone, called Cauldron, was controlled by Crow from a mobile command centre. The project, hoping to shore up public support, sent Crow to control Cauldron in busting up several gangs and gunrunners. Unfortunately, Dabney Donovon, for fun more than anything, managed to take control of Cauldron and cause him to run amok, forcing a confrontation with Superman. Dabney relinquished control, which allowed Crow to control the clone long enough to help Superman save some lives from a collapsing building, but Cauldron was apparently destroyed in the incident.
Later on, the technology was sold by someone at Cadmus to a terrorist named Nikolai Karpov, who rebuilt and recloned Cauldron, significantly augmenting its abilities. It could now absorb heat, and was much more powerful than its predecessor.
