Enraged Wonder Man & Wonder Woman VS. Darkseid(current)
Wonder Woman on her own I think would get a$$ raped by Darkseid, don't get me wrong, she would hold her own and give Darkseid quite a fight, but would eventually still lose, but with the Ionic Avenger fully enraged, could they stand a chance?
Considering the powers of Darkseid, the fact that Wonder Woman can't handle Darkseid herself, and a fact that Wonder Man is a pretty crappy attempt to substitute Superman, then this one goes to Darkseid.
