Queen Europe is King Europe's female counterpart. She only appears in two comics, "Women Around the World" and "What comes around goes around," in which King Europe accuses her of being a witch, claiming that she has been making people sick and making the milk supplies go bad. However when he reports this to the Vatican, the Vatican turns on him, saying that, "only heathens believe in witches" and punishes him for accusing Queen.
It is unknown if Queen Europe is King Europe's sister or related in some other way
