Stephanie teamed up with the greatest female superhero of them all when a senator was attacked by Professor Ivo's robotic female cyber-sirens at the White House. The robots only controlled men, so Wonder Woman called Stephanie and several other superheroines to aid her in defeating the robots and tanks. With a cry of "On my word, warriors! Forward!" the women attacked. Stephanie let Wonder Woman know when Supergirl grabbed the flying tank, yelling "Wonder Woman! She's got it! Supergirl's on the case!" This allowed Wonder Woman to smash two vehicles together and take out Ivo's control. Wonder Woman thanked all the women present for the victory and told them they fought like Amazons.
