While originally functioning in their own corner of the shared universe, the Guardians crossed over with the other heroes for Avengers: Infinity War and Endgame.
But it turns out that they were originally only going to get a cameo in Infinity War.
Since they first arrived in theaters in 2014, the Guardians of the Galaxy have become fan favorite characters within the Marvel Cinematic Universe.
Moviegoers loved seeing them interacting with The Avengers, especially Thor.
