The Kidnapping of Peter Quill was an attempt by Yondu Udonta's Ravager faction, acting on orders from Ego, to abduct Peter Quill.
In 1980, a Celestial named Ego visited Earth and conceived a child with Meredith Quill, who later named her newborn son Peter. Eight years later, Ego hired Yondu Udonta and his faction of outlaws to retrieve Peter for him.
By that time, Peter knew very little about his birth father except for the stories that Meredith told him, in which she described him as an "angel". Peter grew close to Meredith, who called him her "little Star-Lord" and gave him a cassette that he constantly played on his Walkman.
Their peaceful life was soon shattered when Meredith was diagnosed with brain cancer, which was caused by a tumor Ego had inserted into her head, and hospitalised.
While visiting Meredith in her last hours, Peter was presented with a gift and a letter before watching as she passed away. He was then escorted out by his grandfather, who went back into the room to be with her. A saddened Peter ran outside and wept openly as Yondu's M-ship descended from the sky and prepared to abduct him.
Yondu neglected Ego's orders and raised Peter as his own son, teaching him to become a master thief. By 2014, Peter had adopted his mother's nickname and was known throughout the galaxy as Star-Lord.
