Mary Sue was a girl who got it on with every male in the galaxy. Despite this, she was still a virgin. Every male wanted to have relations with Mary Sue, as did some of the females. Mary Sue was Han Solo's sister. Unlike her brother, though, Mary Sue was extremely Force-sensitive, even more so than Luke Skywalker.
Mary Sue had one additional Force power, known as Force Slash. With this technique, she could possess two males and make them want to have relations with each other—which they would, with great frequency and vigor. Darth Darth Binks once attempted to destroy her homeworld of Earth, but since it didn't exist anyway, he was unsuccessful.
