回复 :Professor Charles Francis Xavier, who has the mutant ability to read minds, searches for new mutants to train them how to use their powers for good and to prevent the mutants from harming themselves and others at his School for Gifted Youngsters. His opposition, Magneto Master of Magnetism, is doing the same thing, but for evil purposes. He has made Mystique who is a shape-shifter, a principle of his high school to gather evil mutants to prepare them for war against non-mutants. The most interesting plot of the story is that all the heroes and villains attend the same high school. The classic battle of good vs. evil has begun again.
