There have been recent rumors that a "reinvented" villain team will join the MCU Cinematic Universe, and the name of the movie is the name of this team, which is "Thunderbolt". There is news that the film will be released as the work of the 5th phase of the MCU. If this news is true, general Thunderbolt Ross, who has already appeared in the movie, will probably be able to achieve the transformation of the "Red Hulk" through the Thunderbolt movie.
General Sandport Ross, played by William Hurt, joined the Marvel Cinematic Universe in 2008's Hulk, and since his appearance, fans familiar with comics have been waiting to see him become the "Hulk." Since "Hulk" has only been filmed for one episode and has not had any information about a sequel, this hope once seemed out of reach. It wasn't until Captain America: Civil War that William Hurt returned as Rose. Since then, he has become a regular visitor to the Marvel Cinematic Universe, but his story does not show any connection with the transformation of the "Red Hulk". Instead, Rose is positioned as the villain of Marvel's Avengers, and his views on superheroes with superpowers he can't control are growing, though that may eventually lead him to join Thunderbolt and gain his own superpowers.
General Ross and the "Red Hulk" in the comics
In the introduction of Marvel comics, Ross is usually portrayed as a high-ranking military officer or government official, the father of Bruce Banner's beloved Betty Rose, and banner's disapproval father-in-law. So Ross and Banner's relationship is rarely friendly in the comics and more often completely hostile.
Ross, who is the head of Banner's Hulk program, sees the Hulk as a threat to his country and his loved ones, so he is bent on killing the behemoth, and does not increase his compassion in the slightest when he learns that Hulk and Banner share a body. Like many stubborn villains, he has always believed that what he thinks and does is the right thing to do.
In the 2008 Marvel comics, Rose's efforts to stop the Hulk reached a new height, and the "Red Hulk" also appeared in the comics for the first time at this time, Banner's Hulk heart echoed the "Red Giant", Banner soon discovered that the identity of the "Red Hulk" was Rose, although he could not believe that this was true, but the "Red Hulk" was quickly on the side of justice. Because of the foundation of these origin stories in the comics, if Rose really needs to become a "Red Hulk" in the MCU, the film's explanation doesn't need to be too complicated to make sense.
The possibility of the film turning Rose into a Red Hulk
In the comics, the Red Hulk is the result of the "MODOK" intelligence group trying to create a super soldier with the participation of Dr. Samson. Because Samson disappeared from the Marvel Universe before he could actually act, and "MODOK" has not yet appeared in the Marvel Universe, it seems unlikely that they will be the origin story of the "Red Hulk" in the MCU. Even without them, Marvel Studios has many ways to turn Rose into a "Red Hulk." After all, the Marvel Cinematic Universe already has two super soldier serum problems that ultimately create the example of a supervillain.
The first was John Schmidt, who turned into a red skull and disfigured himself after injecting himself with the super soldier serum of the early Dr. Abraham Erskine. While Erskine believes that the serum may have simply amplified Schmidt's evil nature, it has not yet been fully stated whether Schmidt's condition was caused by a problem with that version of the serum. Then what happened to Captain Emil Bronsky, became a terrifying creature of abomination after Rose recruited him to fight the Hulk by taking a super soldier serum mixed with Bruce Banner's blood. Of course, adding blood was Bronsky's own idea.
Although there is no direct message about the members of "Thunderbolt" in the movie, it makes sense for Ross to choose to join Zemo, American Secret Agents and others as the initial members of "Thunderbolt". Ross's position on the team can be as simple as that of a government liaison officer in charge of operations, responsible for various actions, but it is also a great opportunity for him to achieve the "Red Hulk" transformation. This would give Rose, who has long dealt with superpowers and struggled to take advantage of the situation, the power he has always desired, and provide the opportunity to show. The Falcon and Winter Soldier episode has revealed that other versions of the Super Soldier serum may also exist, so Marvel Studios may have planted the seeds for him to undergo this huge change.
In the episode "Falcon and Winter Soldier", it was revealed that in fact, there are more super soldiers in the MCU than previously described, and the super soldier serum is also more. Although one may not understand why Ross would risk side effects (turning into a monster) using it. This question is actually very well explained in the movie.
Rose himself has been shown in the film as a very proud man, and he will not do nothing in the face of the constant threat of the earth and the unsupportive attitude of some other heroes. In addition, he had a brief appearance in Black Widow, where he was mentioned for his second bypass surgery and deteriorating health. His condition, then, may have prompted Ross to seek treatments that go beyond conventional modern medicine. It's possible that Rose knows that his time is limited, and even if becoming a "Red Hulk" doesn't save his life, it gives him the opportunity to do what he wants to do in a limited amount of time. Someone like Rose wouldn't be obscure, and if he knew that using the serum would rejuvenate himself, and even that mixing "properly" with Banner's blood would have more benefits, then it wouldn't be surprising that these made him a "Red Hulk."
The relationship between "Thunderbolt" and the Red Hulk
The place of "Red Hulk" in the Marvel Cinematic Universe "Thunderbolt" is very meaningful. He must not have been the same team that Baron Zemo formed, and in fact Rose led his own team in the comics. This takes place after the Phoenix Wars, where the Hulk leads a team of Erica, the Punishers, Venom, Deadpool, Ghost Riders, Mercy, and The Leader. Now "Thunderbolt" is likely to be formed in the MCU, and this team can be a version of Zemo, a version of the Red Hulk, or a combination of the two versions. If Marvel changed the name of the Thunder because of Ross's involvement, it is entirely possible.
Marvel can wait to add Rose's "Red Hulk" transformation in "Thunderbolt", but the fourth stage can also make some preparations for this transformation, especially if Rose will appear in "Female Hulk", Disney+ this drama may make Rose's transformation into the Red Giant further, and the 5th stage of "Thunderbolt" and "Hulk World War" are bound to complete the evolution of "Red Hulk".
