Star-Lord is a Level Pack character from the franchise Marvel Cinematic Universe.
Background (From Brickipedia):
Peter Jason Quill, also known as Star-Lord, is a half-human and a half-celestial who was abducted by the Ravagers. He was born to his mother, Meredith Quill and to his father, Ego. After his abduction, he began building a name ("Star-Lord") for himself as a legendary outlaw, eventually becoming the founder and leader of the Guardians of the Galaxy team.
Deciding to leave the Ravagers, he stole the Orb, unintentionally becoming a part of the Quest for the Orb. During the Quest, he formed an uneasy alliance with Gamora, Drax the Destroyer, Rocket Raccoon, and Groot, and helped stop Ronan the Accuser from destroying Xandar.
After the Battle of Xandar, he left with the other Guardians to do "a little bit of bad and a little bit of good".
