io9.com has created a list of "the green-skinned ladies who make the universe a more colorful place." Naturally, Oola from Return of the Jedi shows up:


"Oola (Star Wars): Unlike the Orion women, Oola is a bona fide slave, a Twi’lek tragically tricked into becoming a dancer for Jabba the Hutt. There, she was starved, forced to service Jabba, and beaten for any disobedience. Just before she believed she would be rescued by Luke Skywalker, Oola performed one final dance for her master, but when Jabba pulled on the chain around her neck, beckoning him to her, she defied him, pulling back until Jabba tugged her over a trapdoor and dropped her into the chamber of his hungry rancor."
