james gunn revealed that in addition to Peter Quill / Starlord as the main protagonist of the Guardians of the Galaxy trilogy, Rocket He is the “secret protagonist” of the Marvel film series.
Speaking to Total Film, Gunn said: “Rocket is the secret boss of Guardians of the Galaxy, and he’s always been the center of it for me, and that’s really satisfying. The reason I came back and I decided to make this film was because he really felt the Rocket story needed to be told, and he got hung up after book 2.”
He also expanded on his Twitter profile, where he confirmed that wasn’t just the case with Vol.3, and that Rocket should be considered the secret protagonist of the entire trilogy. Since it looks like Rocket will be getting some major character development in Guardians of the Galaxy Volume 3, it looks like we’ll see what exactly Gunn is referring to with his “secret protagonist” phrase.
