Oh, Starfire, easily. Raven's got all this extra baggage about emotional junk, she's rather uptight too. Starfire just wants to have fun and enjoy life, and if it means trampling on Batgirl, even better. Ruining other girls is, like, the hottest awesomest thing a girl can do. Girls like her are princesses and queens, and being the princess/queen means destroying weaker girls sometimes. I would be honored to serve someone like her.
