Peter Quill's family

'This article refers to all of Peter's relatives. For separate pages see, Quill family, Udonta family, and the House of Ego.'

Biological Parents
Peter's mother was Meredith Quill. She was a mortal on earth who fell in love with a spaceman. This spaceman was Peter Quill's father, Ego the Living Planet.

Adoptive Parents
Shortly after being abducted by aliens, Yondu Udonta raised a young Peter Quill since he was eight years old.

Siblings
Peter had multiple half-siblings through his father, Ego. However, they were all killed by their father when they failed to inherit the Celestial gene. He is however the adoptive brother of Mantis, who was adopted by Ego after he found her on an abandoned family.

In a way, Peter and Kraglin Obfonteri were like brothers growing up, but they had sibling rivalry with each other.
