The fate of the entire Marvel Universe hangs in the balance as Earth's mightiest heroes face their greatest challenge! Summoned across the stars by the mysterious and unbelievably powerful Beyonder, the Avengers, Spider-Man, the Fantastic Four, and the X-Men are set against their deadliest foes on the mysterious planet known as Battleworld - with the winner promised the ultimate prize. But as battle lines are drawn, new alliances are forged, and old enemies clash, one among them is not willing to settle for anything less than godhood.

The Avengers journey into deep space, where they unite the intergalactic races against the Builders - deadly aliens who seek to destroy the known galaxy. While the heroes are gone, Thanos sets his sights on Earth, sending the Black Order to launch the assault. It falls to the other heroes of Earth - the Inhumans, the Black Panther, Namor the Sub-Mariner, Doctor Strange, the X-Men, and more - to defend Attilan, Wakanda, Atlantis, and the rest of the planet. To defeat Thanos, the defending forces will need to deploy a new weapon - one that may be as deadly as the invading force.

Hey, hey, book lovers, take off those big thick glasses - this is Deadpool speaking! Sorry Marvel, somethin' happened to your copy guy. Anyway, this is my first prose novel, and they got this dude Stefan Petrucha to write it. He's good people. He's written novels and comics. But here's the thing: This book is about dogs. Dogs that turn into big nasty monsters. And then I gotta kill 'em. Thing is, I like killing people - the ones that deserve it, anyway - but I won't kill dogs. So that's what we call a character dilemma.

Betrayed by Earth's heroes and exiled into outer space, the man-monster known as the Incredible Hulk has landed on the distant planet Sakaar, ruled by the tyrannical Red King. Sold into slavery, the Hulk becomes the Green Scar, the planet's mightiest gladiator! But his new masters get more than they bargained for when he forges a bond of brotherhood with his fellow fighters: crafty insectoid Miek, the horrific Brood, wise rock-man Korg, Shadow Warrior Hiroim, noble-born rebel Elloe, and her loyal guardsman Skee. Together, these gladiators start a revolution.

In a dark and dangerous future, the mutant-hunting machines known as the Sentinels rule America with an iron fist. Almost all mutants and superhumans have been exterminated.

Now Kate Pryde, former X-Man, must travel back in time and warn her present-day teammates of the coming danger - and hopefully prevent this horrible future from ever taking place!
