Ponyville is obsessed with a new comic book about local superheroes The Mysterious Mare Do Well and Rainbow Flash.

Mare Do Well's secret identity as a mild-mannered unicorn librarian is unsettling enough, but the comic writer seems to know much more than they should about Ponyville's secrets, and possibly even its future.

If the comics are right, Ponyville is going to need real heroes. Heroes like Rainbow Dash and Twilight Sparkle.
