World War Hulk (2007)

Double-sized first issue! Exiled by a group of Marvel heroes to the savage alien planet of Sakaar, the Hulk raged, bled and conquered through the pages of last year's Planet Hulk epic, rising from slave to gladiator to king. Now the Hulk returns to Earth to wreak his terrible vengeance on Iron Man, Reed Richards, Dr. Strange and Black Bolt -- and anyone else who gets in his way. Stronger than ever, accompanied by his monstrous Warbound gladiator allies, and possessed by the fiercest and purest rage imaginable, the Hulk may just tear this stupid planet in half.
