Ghost of a flea

The first superhero comic ever published, Action Comics no. 1 in 1938, introduced the world to something both unprecedented and timeless: Superman, a caped god for the modern age. In a matter of years, the skies of the imaginary world were filled with strange mutants, aliens, and vigilantes: Batman, Wonder Woman, the Fantastic Four, Iron Man, and the X-Men—the list of names as familiar as our own. In less than a century, they’ve gone from not existing at all to being everywhere we look: on our movie and television screens, in our videogames and dreams.
