If you noticed, Thaddeus Ross will be the President of the United States in “Captain America: Brave New World,” which will give him the benefit of accessing many secret projects. In Marvel Comics, Thaddeus Ross gets transformed into Red Hulk, MCU will not break the pattern so he is likely to be the MCU’s Red Hulk.

The brief cameo of Red Hulk is insufficient to confirm if he was actually Thaddeus Ross who transformed into him or not but based on Marvel Comics, we can say that he definitely has a backstory in the MCU. Thaddeus Ross first appeared in 2008’s The Incredible Hulk, but he was Lt. General at the time. He then became Secretary of State in Captain America: Civil War, and in 2025, he will be the President of the United States.

A recent theory on Reddit r/Marvel Theories, posted by BradmanTV, explains how Thaddeus Ross will become the Red Hulk in the movie. In Infinity War, Thaddeus Ross spoke about his heart surgery to Rhodey, and the government is expected to use Tony Stark’s research to save him.

In 2013’s Iron Man 3, Tony saved Pepper from the Extremis. The government scientist may use it on Thaddeus Ross to save him and we know that extremis gives the ability to bear enormous heat and if mixed with gamma radiation, then the outcome will likely lead to the formation of a red hulk.
