"What is your heritage, Mr. Quill?"
"My mother is from Earth."
"And your father?"
"He ain't from Missouri, that's all I know."
―Ayesha and Star-Lord

Peter Quill was born in late 1980 to Meredith Quill, a human, and Ego, a Celestial, making him a hybrid of the two. His conception was all part of a plot set up by his father to produce a second Celestial, whose power he could use to complete the Expansion, which involved assimilating millions of worlds into Ego's very being. Peter was only one in thousands of different children that Ego conceived over the course of millions of years, though all who came before him were killed and thrown aside, failing to meet Ego's expectations.

Quill never knew his father, as Ego left Earth shortly after his son was conceived. Quill grew up in St. Charles, Missouri under the care of his mother and grandfather. Throughout his childhood, Quill became something of a wild child, getting into numerous fights. He became very close to his mother, who brought together some of her favorite songs from her childhood into a mix tape she titled "Awesome Mix Vol. 1". When other children asked where his father was, Peter told them that his dad was David Hasselhoff and was busy with his career.

Quill was suddenly abducted from Earth by the Ravagers. Their mission was to take him to his father in deep space but their leader, Yondu Udonta, knew very well of Ego's nature and plans. So, he instead decided that they would keep Quill as their own and chose never to tell him about his father. To help Quill understand the various languages out there, he had a translation chip surgically implanted in his neck.

"Twenty years, you been throwing that in my face, like it's some great thing, not eating me. Normal people don't even think about eating someone else! Much less that person having to be grateful for it. You abducted me, man. You stole me from my home and from my family."
