"Planet Hulk" is a Marvel Comics storyline that ran primarily through issues of The Incredible Hulk starting in 2006. Written by Greg Pak, it dealt with the Marvel heroes' decision to send the Hulk away, his acclimation to and conquest of the planet where he landed, and his efforts to return to Earth to take his revenge. There was also a special Planet Hulk: Gladiator Guidebook publication by Anthony Flamini and the storyline's main writer Greg Pak, similar to the Official Handbook of the Marvel Universe detailing the characters, races and cultures within the storyline. Elements from the storyline have been adapted into other media, including an animated film of the same name, as well as the live action film Thor: Ragnarok. Publication history The storyline's main writer Greg Pak describes the origin of the ideas: "The inspiration for sending Hulk to an alien planet where he'd battle monsters as a gladiator came from Marvel Editor-in-Chief Joe Quesada. I loved the idea from the minute I heard it, so I was blown away when they told me I had the gig and even more blown away when they basically cut me loose to create the whole world". He also drew from real-world history: "I got inspiration for the story by reading about the real lives of gladiators in ancient Rome and from the stories of figures like Genghis Khan and more contemporary warlords, dictators, and political leaders. Sun Tzu's Art of War and Joseph Campbell's Power of Myth played a big role in helping me think through other aspects of the story". The story's roots began in the New Avengers: Illuminati one-shot and Incredible Hulk #88–91. The main storyline was told in Incredible Hulk #92–105, and Giant-Size Hulk vol 2 #1. It led directly to the World War Hulk crossover, and inspired the Son of Hulk series. The story was re-examined in What If?: Planet Hulk. In October 2017, a sequel, titled Return to the Planet Hulk, starring Amadeus Cho as the Hulk, was released as a part of Marvel's Marvel Legacy initiative.
