Artist Randall Blake was a cat burglar specializing in stealing international high-end art and seducing women from his bar headquarters, La Brasserie de Bohême. He could transform himself into a dark gas or create dark matter shields or blasts with his hands. Discovering that he and Lexa Pierce were after the same set of artwork, Randall stole the painting she had acquired. He then seduced her before tricking her into being caught while attempting to steal the last painting in the set. But thanks to a tracking device Lexa had planted on his earlobe, Mutant X was able to turn the tables on him.
