By assessing the characterization of the heroes and villains, the plot lines, and the allegorical narratives present in the comics, this study connects the shift in the superhero paradigm represented by the X-Men with changes in cultural perceptions about diversity, difference, and individuality, as well as Americans? growing wariness of the U.S. government in the post-Vietnam era.
