Avengers: Endgame fan theory – The Braddocks are related to Captain America

Fan theories regarding Avengers: Endgame show no signs of slowing down, and a recent one suggests a link between Captain America and a mutant.

A month has passed since the release of Avengers: Endgame, and fans all over the world keep on dissecting the events, alternate timelines, and the (possible) connections between characters of the Marvel Cinematic Universe and Marvel comics.

Now that we are living in the Fox/Disney merge era, Marvel fans have been wondering if Avengers: Endgame set the foundations for the introduction of the mutants in the MCU, and have been looking incessantly for clues. We won’t know if Marvel did so or not until someone from the studio confirms or denies it but, in the meantime, a new fan theory has emerged, suggesting a link between Captain America and the characters Captain Britain and Psylocke.

This theory was posted on Reddit and refers the scene in Avengers: Endgame where Tony Stark and Steve Rogers travel back to the ‘70s to get the Tesseract. Steve hides in a room and sees Peggy Carter, who mentions an Agent Braddock. The Braddocks this refers to are Brian (Captain Britain) and Betsy (Psylocke), of which only Betsy is a mutant.

The theory suggests that when Steve went back in time to spend the rest of his life with Peggy, he used an alias like, let’s say, Agent Braddock. Steve and Peggy had children, and these (or perhaps their grandchildren) became Captain Britain and Psylocke. Now, Endgame left us with a couple of alternate universes here and there, so this theory can get a bit tricky.

The rules of time-traveling in the MCU can be confusing but, in essence, the main rule says that if you go back in time and change something, you create an alternate universe. Wouldn’t this mean, then, that Peggy and Steve’s life together is entirely apart from the Steve of the main timeline (that is, the one that goes back in time to the ‘70s and then back again), and so they wouldn’t meet?

Supposing Steve from the main timeline goes back to a time where he and Peggy are together and that he did used the alias “Braddock”, fans are speculating how the mutant gene jumped to Betsy. Was it a consequence of the Super Soldier Serum? Or could it have been something provoked by an accident or experiment, like with the Maximoffs in the MCU? So many questions, not one answer available… for now, at least.

Until Avengers: Endgame is released on Digital, DVD, and Blu-ray, we can have some fun with all the theories that pop up – and prepare for a new wave of theories and findings once we can watch it over and over again.
