The Queen is an alluring and cryptic beast who captivates men with her charm and devours them in her palace. Very determine to secure her meal, she takes form in any matter of water, whether it be droplets or steam. After kidnapping the infatuated victim from their home, she takes them back to her castle where she performs a ritualistic dance for them. She endows them with a necklace of shells, then she transforms into her monstrous true form and strips them clean of their flesh and muscle, leaving only a smiling skeleton behind. Her strange ocean world can be accessed from seemingly any body of water. She can also take the form of a canine to seduce male dogs.
Some time later, the Black Queen returned along with many other antagonists for Eustace's dodgeball revenge game. Compulsively hungry, she took one of Muriel's finger sandwiches prematurely, revealing their cover as a "men's club." Later in the game, she appeared using a puddle of Sports Swill that Courage spit up, and assaults him with various sea life. As the end seems near, and the Queen has equipped a rocket conch shell, Courage unleashes a massive scream, causing a tremor that the villains fall into.
