World War Hulk Prologue: World Breaker #1 (2007)

World War Hulk - Casus Belli
The Hulk rockets towards Earth, and a reckoning with his enemies, many of whom he once called friend. They shot him into space, banished him to the savage world of Sakaar, where he became a slave, a gladiator, a rebel, and finally an Emperor. And then the ship that carried him over this vast distance, to this place where the raging Hulk had found peace, destroyed Sakaar.But the Hulk does not travel alone. His Warbound brethren, fellow gladiators who aided him in establishing his reign on Sakaar travel with him to help him achieve his vengeance. But his boundless rage is a threat even to them. In battle, the only faces he sees are those of his enemies, causing him to lash out at his friends. Can the Hulk harness his rage, and bring it to bear solely on those he feels deserve his wrath? Meanwhile, on Earth, Dr. Leonard Samson and the recently de-powered She-Hulk argue over who struck the first blow in the war between the Hulk and the rest of the Marvel Universe.
