Betty I and Betty II, a.k.a. The Bettys (Cyb and Patricia Barnstable) are the navigators and pilots of the ship. They are completely identical, with identical red-hot passions for Quark. One of them is a clone of the other, but each claims the other one is the clone. They have a tendency to speak in perfect unison and have exactly the same thought at exactly the same time. Quark, when describing his crew, explains that he is "extremely fond" of Betty, but he is not sure which one.
