In an interview with Empire, Gunn reveals that Peter Quill's lineage in Guardians Of The Galaxy 2 will deviate heavily from the source material.
"There have been a lot of documents passed around about who Peter Quill’s father is between a select two or three of us. That’s been part of the plan since the beginning, that’s something I had to work out before we shot the screenplay. We wanted to make sure Yondu’s place in everything made sense and it does, so it’s all very specific stuff. It’s definitely not the character who it is in the comics, I’ll say that much."Dork Note: They'll make Starfox Peter Quills father to closely connect him to Thanos directly and further explain his ability to hold a Infinity Gem.
