10 MCU Fan Theories That Just Won't Die

10. Natasha Romanoff Is Alive

It was one of the most emotional moments of the entire Marvel Cinematic Universe, if somewhat overshadowed by Tony Stark’s death later in the movie, when Natasha Romanoff sacrificed herself for the good of the Avengers and for the universe as a whole.

Thor wanted to use the stones to bring her back, while Bruce Banner apparently tried when he brought everyone else back, but as Clint said, it couldn’t be taken back. That was what the Red Skull said anyway, as something called an everlasting exchange doesn’t feel like it’s easily undone.

However, MCU fans aren’t convinced that Hulk didn’t bring her back. After all, how could he possibly know? In theory, if she would have returned, surely it would have been on Vormir where she died, with no way of letting anyone know and no way of escaping.

Even in the Loki trailer, the image of the back of Sylvie’s head on Lamentis did look like Natasha’s Infinity War look, and the fires of this particular theory were stoked. Naturally this was disproven in Loki, not to mention the that timeline wouldn’t have worked in terms of her hair style, but fans have not been deterred. The thing about this theory is that it likely won’t ever be fully debunked, which will always be enough to give fans hope.
