Circe is a DC comics Wonder Woman Villian. Her character is based on the goddes/sourceress Circe from the The Odyssey who had a thing for seducing men and turning them into pigs and bears. In the comic books, she likes to do the same animal transformations, but generally, she is a magic caster.
This particular costume is only seen in the DC Universe Online game that was released this year.
