Marvel has a long history of alien races whose empires span galaxies. Recently, they all went to war in a crossover by Jonathan Hickman called "Imperial." In this episode, the Doombots will establish who these space empires are, and why they all started shooting each other. Plus, there's a huge spoilery surprise about who's actually behind the whole thing. Black Panther, Hulk, and Star-Lord are some of the major players this time around, and we'll discuss what they're up to, too.
