There's a marvelous theory that Mario is actually the villain of the Super Mario Bros games (there's even a delightful indie game built around flipping the hero/villain roles in a similar manner). The idea is that Princess Peach wants Bowser to take her away from that evil plumber, hence the frequent kidnappings in which she hardly resists. The above image from Reddit is a little alternative history for you from the end of Super Mario Bros. 3 for the Nintendo Entertainment System in which Mario slays Bowser with the awesome power of the Hammer Bros. suit and then attacks the princess rather than save her. Viewed this way, Mario does indeed become the villain of the piece with Bowser cast as Peach's protector and guardian. Now don't you feel bad for sending Bowser plummeting into the darkness? Next time: Samus Aran, xenocidal killing machine.
