Warning: Contains SPOILERS for Guardians of the Galaxy Vol. 3!Star-Lord’s grandpa’s name in Guardians of the Galaxy Vol. 3 might tease a shocking change to Peter Quill’s backstory for the Marvel Cinematic Universe. The MCU has revealed plenty of information about Star-Lord’s past throughout the Guardians of the Galaxy trilogy. His mother died when he was only eight years old, leading to him being abducted by Yondu, who was on orders to deliver Peter to Ego, his Celestial father. It was not until Guardians of the Galaxy Vol. 2 that Star-Lord met his father and a bigger family tree became possible, leading to the revelation that Mantis is Peter’s sister.
