X-Men

Origin:

Mutants, a small percentage of the human population that carry the X-gene that grants them superhuman abilities that emerge when the mutant begins puberty, began to emerge in the late 1980's and early 1990's; and were feared by the rest of humanity because of the majority of mutants being unable to control their abilities. Professor Charles Xavier, a mutant rights activist and secretly a powerful mutant telepath himself, decided to transform his family estate in Massachusetts into a school for young mutants to not only learn to control their abilities but continue their education. By 1993, Xavier had an entire class of students attending the school, one of which was Carol Danvers--Ms. Marvel--who would go on to become a founding member of the Avengers.
