Doom Patrol (Doom Patrol #115)

“THE MUTANT MASTER.”

Three monstrous atomic mutants plan to destroy the world, and the Doom Patrol is defeated in its encounters with the trio. At the same time, Madame Rouge's split personality, aggravated by the mental coercion of both the Brain and the Chief, causes her to become two separate beings, who battle to the destruction of her evil half.
