8. Miss Martian
Miss Martian (AKA M'gann M'orzz or Megan Morse) is a young White Martian who travelled to Earth to follow in the footstep of the Martian Manhunter - a Green Martian superhero who has been a major part of the Justice League of America. She struggles with her past as a member of a race which is not well trusted or regarded on Earth and, as a result, initially used her shape-shifting powers to make herself appear green. She is generally associated with the Teen Titans, so it would probably require a Teen Titans movie to see her hit the big screen (which would be very cool, incidentally). As a White Martian, she possesses powers such as flight, superhuman strength, invisibility, intangibility, shapeshifting, optic force blasts and telepathy. I've noticed that there is a minority group amongst fanboys who have something of a fetish for "alien girls" and I'm sure they'd go wild for a live adaptation of Miss Martian.
