King Sombra steals a car, and he, Queen Chrysalis, Lord Tirek, the Dazzlings, Midnight Sparkle, and the Storm King drive it around quite irresponsibly while planning world domination - or intending to plan world domination, but getting a little distracted. It doesn't end well.

Rated T for drinking and driving. Don't do it at home. Or anywhere else.

Not meant to fit into canon of course, due to major inconsistencies with the show (such as, Sombra, Midnight, and the Storm King being dead, or no cars in Equestria).
