The Marvel Cinematic Universe has given us some of the greatest summer blockbusters of all time, creating a multibillion-dollar film series that's had fans following it for over a decade. "The Avengers" movies have some of the best comic book characters ever brought to life. With over 20 movies that include Avengers characters, we get crossovers, cameos and storylines that keep us interested and make us want more.
For those fans who didn't follow the comic books, we first heard of the Avengers initiative in 2008, when Nick Fury (played by Samuel L. Jackson) showed up in a post-credit scene, and we were excited to see more. Soon, the series of films took flight, and things went crazy. The only year we didn't have a stand-alone film or "Avengers" film with one of these MCU characters was 2009, and for 11 years, these characters have practically become part of our families.
If you are an MCU fan, you can probably spot your favorite characters no matter what kind of hairstyle they have or how their costumes changed. However, do you know which "Avengers" movie these changes occurred in? Take this quiz to see if you can guess which "Avengers" movie we're talking about (don't worry, we'll show you a screenshot). SPOILER ALERT: If you haven't seen all four "Avengers" movies, you will probably want to put this quiz on hold for a minute.
