Of course, many viewers believe Pietro is not actually Pietro, and think the episode heavily hints that he is actually the Marvel villain known as Nightmare.
These fans think Marvel producers added a visual reference to Wolverine, the mutant played by Hugh Jackman, in WandaVision, in the form of Pietro’s hairstyle.
The latest episode of WandaVision featured what some fans believed to be an extremely rare Marvel Cinematic Universe reference to one of the studio’s most famous characters.
His arrival has led to what some fans believe to be another X-Men reference, though, which would be particularly exciting considering the MCU is set to introduce the X-Men in future films thanks to Disney’s acquisition of Fox.
