Hulk was banished from Earth to the far away planet Sakaar, where he became a gladiator. Now he is stronger than ever and blinded by rage over the death of his family. With the support of his Warbound, Hulk now returns to Earth, bent on exacting revenge on those who wronged him, and anybody else who dare stand in his way! New York becomes a gladiatorial arena as the mightiest heroes must pit themselves against World Breaker Hulk.

This expansion adds an epic war between the strongest characters in the world. Consumed by anger, Gladiator Hulk is ready to smash anyone who gets in his way. When even the Olympian Hercules and Ares falter, Iron Man will don his massive Hulkbuster armor to attempt to stop Bruce Banner. The Sentry could be our last hope, as long as he can resist being consumed by The Void.
