[jtjwognm] Superhero mind control

At first, it seems the superhero maintains his or her secret identity with a change in costume, a common trope.

Later, it is revealed that the superhero has mind control powers and is disturbingly erasing knowledge of his or her secret identity from those who learn of it.

Even later, the character's status as a hero begins to be doubtful as the character is revealed to be able to exercise vast mind control over the entire population.  The tales of heroic deeds might be being narrated by an unreliable narrator, also subject to the mind control.
