Michelinie, Grummett and Rodier bring back Cauldron for a second round in Action 731 (March 1997).
Cauldron is a robotic clone, and has the ability to absorb all energy exerted on it, it just makes him stronger. This one speaks with a Russian accent. Lois does some research as Superman fights, and discovers he bemoans the fall of the Soviet empire, and bought the plans for the suit. Cadmus insists they knew nothing of the plans being stolen.
Dan Turpin has been standing alongside Superman throughout the long battle.
Superman finally pulls Cauldron down to Earth’s core, leaving him there.
