In the movie, Avengers: Age of Ultron, new characters are introduced that start off as the antagonists, but later on in the story they become protagonists. These character are: Wanda and Pietro Maximoff.
I was watching WandaVison and in one of the episodes, Wanda opens the door to find her brother, Pietro, at the door. Pietro died in Age of Ultron, and her so called, "brother" that knocked on her door, looks completely different from the last movie. I realized that this is the same guy from X-Men: Dark Phoenix.
Here is a picture for anyone who doesn't know who I'm talking about:
These are both Marvel movies, so it makes me think. Is the Pietro in Dark Phoenix the same one who is related to Wanda in WandaVision? And if so, why don't we see Wanda in the X-Men movies?
