"World War Hulks" is a comic book crossover storyline published by Marvel Comics that ran in 2010 following the "Fall of the Hulks" storyline.
The plot builds on the depowering of Bruce Banner by Red Hulk during the "Dark Reign" storyline and the betrayal of Doc Samson who joined with the Intelligencia to bring about the "Fall of the Hulks" to create an army of Hulks to take over the world. "World War Hulks" will also show the origins of Red Hulk (General Ross) and Red She-Hulk (Betty Ross).
"World War Hulks" is the continuation of an arc that began with the Planet Hulk storyline in 2006-07, that continued into World War Hulk (the Marvel event of 2007), through the short lived Skaar Son of Hulk and into the last two years of both Hulk titles, which have largely focused on the identity of Red Hulk, the depowering of Bruce Banner, and the arrival of Skaar on Earth. The newly announced "Incredible Hulks: Dark Son", which brings Skaar's brother Hiro-Kala to Earth, is the end of the arc.
