Ultimated DC:Circe

Immortal witch and nemesis to Wonder Woman. She is the daughter of Hyperion and Perseis and Hecate's greatest disciple and her magicks allow her to teleport cast incredibly realistic illusions, transform people into animals or animal/human hybrids and cast a mean magic-zap. She recently altered her own body to give herself super strength and durability too. This woman changes costumes so often it's almost impossible to get references for her.

I love this character, but then I seem to have a thing for evil magic wielding women--> Goblyn Queen, the Darkchylde, Circe. They're just so much fun.
