In the Marvel Universe, mutants are humans who are born with a genetic trait called the X-gene which grants them natural superhuman abilities. Due to their differences from the majority of humanity, mutants are subject to prejudice and discrimination and many X-Men stories feature social commentary on bigotry and justice. The X-Men have fought against a variety of enemies, including villainous mutants, human bigots, mystical threats, extraterrestrials, and malevolent artificial intelligences.
