Catwoman (as played by Michelle Pfeiffer in 1992's Batman Returns)
Poison Ivy (as played by Uma Thurman in 1997's Batman and Robin) one of my all time favourite villains- i think it's the red hair...
Gail (played by Rosario Dawson in Sin City)
Mystique (as played by Rebecca Romijn in X Men) Personally my favourite from the comic and cartoons was always Rogue but brought to life this make up is pretty impressive.
And of course i couldn't leave out my all time childhood favourite: She-ra. I always loved the fact she had a double life.... and a unicorn!
