Circe is an extremely minor part of this film, only appearing in the last scene, but she's one that will certainly return in the event of a sequel. A witch that's come in conflict with Wonder Woman multiple times, she reaches out to Ares at the end of the film to offer an alliance.

I'd like to highlight several aspects of Circe's character, namely her wickedness and her conniving nature. A good example of what I'm looking for is just her appearance in Justice League Unlimited.
