Marvel are launching a number of Star Wars comic books from the likes of Jason Aaron, Mark Waid, John Cassaday, and Terry Dodson next year, but there so far hasn't been any talk of a crossover between that universe and the one inhabited by characters like Spider-Man and the Guardians of the Galaxy. Giving us an idea of what that would look like is this stunning piece by Alex Ross which he was asked to do by a friend. Lucky guy, eh? Who do you guys think would win this battle?
