The Incredible Hulk and Betty Ross
Unlike most of comicdom's heroines, Betty was drawn to Bruce Banner way before the inevitable gamma radiation accident coloured him green.
No matter what disaster met Bets -- and everything happened to her over the years, from turning into a freaked Green menace called the Harpy to being poisoned by Abomination -- she continued to love Banner.
Jennifer Connelly was an interesting choice for the role, but Ang Lee's film blew it, and now we have a reboot with Liv not-as-young-anymore Tyler? Urgh. Hulk angry.
