>>86596250Chaotic, the show where 4kids basically tried to make their own card game anime, had an episode where a main character guy and an antagonist girl had a duel where they turned into different creatures and fought each other. The team of female creatures won, but it turned out that the guy was using female creatures and the girl was using male creatures. The episode ends with the characters confused as to who was proven better. I thought it was pretty good; that whole show is surprisingly really solid.
