In the Wonder Woman 1984 movie, Barbara Minerva (played by Kristen Wiig) is an insecure scientist who befriends Diana.  After being exposed to a mystical force, Barbara eventually transforms into Cheetah, arch enemy of Wonder Woman.  Barbara's look evolves almost as much as the character.  From her frumpy 80s style at the outset of the film, to the sexy animal prints she wears later, there is a lot of room to have fun with the era.  Barbara's fully evolved Cheetah form looks like a humanoid cat, so some adaptations to a standard leopard or cheetah Halloween costume can make it look more intimidating and better suited to the character.
