- March 19, 2015: Bleeding Cool mentions that the Hulk will be in Captain America: Civil War in a set of rumors that are immediately discounted.
- June 1, 2015: The website named We Are Wakanda states its sources tell them the film will indeed feature a Hulk, but it will be a new Hulk taken from the comics, not the Mark Ruffalo one that Bleeding Cool claimed.
- Also June 1, 2005: MCU Exchange takes the We Are Wakanda rumor and runs with it. The look at all the possible Hulks from the comics to determine which one’s alter ego has already been adapted into MCU continuity. The Red Hulk (seen to the left) whose alter ego, General Thunderbolt Ross, is already part of the Marvel films and the most recent man who brought him to life on the screen, William Hurt, is already part of the Captain America: Civil War cast seems like the most likely candidate.
MCU Exchange throws their theory out to their sources. There sources come back and state that not only will Hurt be hulking out as the Red Hulk, but that the green Hulk will be back to face off against him in a fight that will make the Hulk/Iron Man fight from Avengers: Age of Ultron look like a slap fight.
So there you have it. You have three websites with three presumably different sources stating that at the very least a Hulk will be in the film, but most likely it will be the Red Hulk.
While General Ross has been a supporting character in the comics for year, his Red Hulk persona only came in existence in 2008. Created after Ross was bombarded with Gamma and Cosmic Rays, Red Hulk has all the powers of the Hulk plus the ability to absorb energy and generate high levels of heat from his body.
If this is true, the question is: where does he fit into the narrative. The film is looking to be crowded the way it is. I do have an idea. It has been revealed that there is an inciting incident that makes lawmakers want to register superpowered individuals. In the comic books, it’s a fight with a villain with nuclear powers who destroys Stamford, Connecticut. A no-holds barred fight between a pair of Hulks could also destroy a city.
We shall see.
