Can anyone give examples of a comic, graphic novel, anime, etc. where the hero or a member of the hero team has a romance with the villain or a member of the villain team? They have to at least kiss, it doesn't count if they only cast intense looks at each other. And it can't be for only one episode because of some seduction plot or temporary insanity or something. Should be an ongoing source of angst that they like each other but are on opposite sides.
