Luthor married the Contessa Erica Del Portenza, and spends his honeymoon on a yacht, manipulating events back in Metropolis through his sunglasses, in the story by Michelinie, Tom Morgan, and Rodier in Action 724 (Aug. 96).
The story continues from the previous issue of Adventures of Superman, and animal hunter Burton Thompson makes a brief appearance, getting arrested.
The Contessa notices that Lex is fiddling with his glasses a lot, but if his plans concern her, she gives no indication.
Lex is controlling a creature called Brawl, a mindless, destructive monster. But he happens upon his wife, who recognizes him.
Just as he is about to identify how did this to him, Luthor fries him.
