One galaxy's heroes are another's villains, and two galaxies' worth of them are in head-on collision - with the Avengers in the middle of a war whose repercussions will haunt them for years! The events that split and shook the Earth's Mightiest Heroes to their foundations end here, and intergalactic boundaries aren't the only lines being drawn!
