Set in the Marvel Cinematic Universe, a new group of superheroes come to rise. They're not Inhumans - they are Mutants; and they are living among us. These Mutants were born with special superpowers, and they manifest at puberty, usually under periods of emotional distress, and their use can be out of control.
Fortunately, under the leadership of Charles Francis Xavier (or Professor X), a special school for these Mutants was founded. In that school, he teaches them how to control their powers. And in this school, a certain number of these Mutants are a team of superheroes, namely "X-Men".
