Red Hulk’s size might be as strong as Hulk was in The Avengers and Avengers: Age of Ultron, but the source material suggests he will be more powerful.
In the comics, Red Hulk is able to absorb energy and release it as heat. This could be an upgrade provided by Samuel Sterns a.k.a. the Leader, who may be looking to create more powerful Gamma monsters than the original Hulk. However, Red Hulk’s upgrades could come with new weaknesses. For instance, Marvel Comics’ Red Hulk seems to grow hotter instead of stronger as he gets angrier, unlike Bruce Banner’s Hulk alter ego.
Captain America: Brave New World’s Red Hulk bears a closer resemblance to Harrison Ford than the MCU’s original Hulk did to Mark Ruffalo in Phases 1-3. Again, this could be the result of an upgrade, as Bruce Banner struggled to control the Hulk for years in both the comics and the MCU, whereas Thaddeus Ross has immediate control over his Red Hulk persona in the source material. However, Red Hulk may still be more feral than his comic book counterpart, at least in during first transformation.
