From publisher blurb: Double Team: Mortus VS Mercy provides two characters for your Mutants & Masterminds games: a villain, Mortus, and a hero, Mercy. Mortus is a partially dead being who rules a pocket dimension where nothing but the undead remain. He seeks to wipe out all life everywhere with the help of his unliving armies. Mercy is a talented surgeon who gained her powers from the shock of an "honor" acid attack. Her suit now helps her with the pain as she uses her newfound powers to heal and help others. Each character is accompanied by three adventure ideas to make it easier to work them into your game.
