There are several notable characters. Etta Candy, for instance, is a friend of Wonder Woman. She provides a different perspective, being a regular human in the story. Cheetah is also a significant character. As one of Wonder Woman's main villains, she represents a different kind of threat compared to the more traditional male villains. Her complex relationship with Wonder Woman, being both an enemy and in some ways a mirror of her own power, makes her a very interesting character in the graphic novel.
In addition to the ones mentioned, there are the other Amazons. Artemis, for example, is an Amazon who has her own set of skills and beliefs. She sometimes clashes with Wonder Woman but also respects her. The Gods in the DC Universe also play roles. Ares, the God of War, is a major antagonist. His presence and his motives for causing chaos in the world add depth to the story, and his battles with Wonder Woman are always intense and full of drama.
