The Hulk has returned. A year ago, a secret cabal of the Marvel Universe's best and brightest heroes decided that the best way to deal with the menace presented by the Incredible Hulk was to remove him to another world where there was no intelligent life to bother him... or for him to destroy. But they failed. The Hulk's shuttle crash-landed on the savage world of Sakaar, ruled by a tyrannical Emperor. The Hulk was captured, and enslaved. From a Slave, he became a Gladiator. The Gladiator became a Revolutionary. The Revolutionary became the Green King. And then, once again, those who had been his friends destroyed his life. The shuttle that had carried the Hulk to Sakaar erupted, destroying the planet at killing Caiera, his Queen who bore his child. Now, the Hulk's rage knows no bounds. Aided by his Warbound bretheren, those that stood with him as Gladiators and accompanied him on his path, the Hulk is returning to Earth to wreak his vengeance upon those who murdered his wife and child. This is World War Hulk.
