Grail: Yes!

Introduced in the New 52, Grail is a relatively new character. But, as the daughter of an Amazon assassin and Darkseid (a connection to both Greek mythology and the Ruler of Apokolips), she’s a formidable villain.
As a hybrid of two very powerful species, Grail could be a worthy adversary for Diana Prince. She has all the same powers, minus the lightning. Additionally, her include Omega Beams (as the daughter of Darkseid) and teleportation (like Ares).
Grail is also a highly skilled warrior, capable of single-handedly defeating the entire Justice League.
Again, maybe Wonder Woman should face a female villain with powers similar to her own in the sequel.
