Since its inception in 2008, the Marvel Cinematic Universe (MCU) has included countless characters in its various movies and shows. Of course, a lot of these characters have appeared in the form of small, brief appearances; aka, cameos. Cameos have become one of the most anticipated parts of any Marvel project. Whether it’s Nick Fury in Iron Man, Thanos in The Avengers, or Matt Murdock in Spider-Man: No Way Home, cameos tend to be very memorable.
