Certainly not as iconic as Batman villains, but Giganta is iconic by WW standards. She's one of her oldest, most recognizable villains.
Lex was created specifically to be a Superman villain. Shoehorning a villain to be WW's arch-enemy is a different thing. DC tried time and time again, it never worked.I offer a counter question. What powers does lex luthor have?
I think what she really needs is better written villains. Her Rogues Gallery is fine, they just need a writer who actually cares to develop them. Cheetah can be a great foil for Wonder Woman when utilized well. Same for Ares, Circe, Dr Psycho, Veronica Cale...There's so much potential for Dr Cyber to be a great villain in the age of technology, Queen Clea can be a shared villain between WW and Aquaman. Almost every obscure WW villain has potential to be great if the writers give them a chance.Yes. She needs new villians
