Rumble's your average angsty punk-obsessed teen. He lives a life full of sex, drugs and rock 'n' roll… And he hates it. Along with his friends First Base, Pipsqueak and Button Mash, the group of friends try to escape their dead-end lives by sneaking through Princess Twilight's portal to the human world.

Retelling the story of Green Day's American Idiot, Rumble and his friends are faced with the challenges of coming to terms with their adulthood and what it means to come of age in a wartime Equestria.
