THE MARVEL UNIVERSE IS DESTROYED...BUT WHAT COMES NEXT?! 
The end has arrived. The unstoppable wave of interdimensional Incursions has obliterated universe after universe until only two remained — the Marvel Universe and the Ultimate Universe. Their collision has left nothing but Battleworld: a vast, patchwork planet forged from the shattered remnants of countless realities.
On this broken stage, heroes and villains struggle to survive. Strange new domains rise. Familiar faces return in shocking new forms. And at the throne of creation itself sits Doom — absolute master of all.
VISIONARY. DEFINITIVE. UNMISSABLE. 
From master storyteller Jonathan Hickman comes the definitive Marvel saga — the cataclysmic event where the Fantastic Four, Avengers, Spider-Man, the X-Men and more face their final battle as the entire Multiverse falls!
