As a trilogy, Guardians of the Galaxy took many liberties with the source material that changed the origins of certain characters while increasing their narrative importance. For example, Rocket, who initially had no ties to the High Evolutionary, was now the villain's creation and his experiences with him changed Rocket forever. However, in the case of Peter Quill, he went from the son of the tyrant King of Spartax to the son of Ego, The Living Planet, now labeled as a Celestial entity in the Marvel Cinematic Universe.
