The classic 'Bad Boy' trope has been around for decades, causing fans to swoon over the villainous stars for one reason or another. Most 20th century bad boys have redeeming qualities to counteract the fact that they don't play by the rules. Sometimes this description applies to fictional characters, and others it is the caricature of certain male celebrities.
Over the years, the bad boy type has changed according to cultural preferences. How bad boys have evolved is determined by the latest trends in attraction, and what bad boys looked like throughout history depends on whether or not the fans of that decade were drawn to magicians, lawbreakers, fortune, or selective weakness.
