The first time we meet young Peter Quill in #GuardiansOfTheGalaxy, we learn he has a black eye from fighting with kids who were torturing an animal.
Peter Jason Quill was born in 1980 to Meredith Quill and Ego, making him a hybrid of human and Celestial. 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.

In his new role, Peter can survive in space, fly faster than the speed of light, and generate a personal force field. His other abilities include being able to recover from injuries quickly, super human strength, and universal language translation.
Yep, he's still got his powers. In fact, you never truly saw him harness his powers in the film. He was taught to harness Ego's power.
Peter Quill is a half-god but has seemingly lost his celestial status. Peter Quill (Chris Pratt) is the son of Meredith Quill (Laura Haddock), a human, and Ego (Kurt Russell), an all-powerful celestial. Born on Earth, Quill later took on the superhero moniker Star-Lord, a nickname from his mother.
If all you're asking about is physical strength, right now Quill doesn't appear to be stronger than Thor. Looks can be deceiving. But if what you're asking for is a total comparison of superhuman powers, then—well—Thor doesn't stand a chance.
Peter Quill is semi-immortal in the comics thanks to his hybrid Human/Spartax physiology and the fact that he stole the source of power from the gods. This means that he ages much more slowly than a regular human being. In the MCU, however, Star-Lord is not immortal.
Ego was a Celestial, a primordial and powerful being, and the biological father of Peter Quill and Mantis.
In Guardians of the Galaxy Vol. 2, Peter's father, Ego, claims to be a Celestial who has his own unique abilities. At a glance, he resembles nothing of the Celestials in Eternals, but his differences may explain where he came from. In the comics, Ego was never a part of the Celestials in the Marvel universe.
Personally, Thanos is physically and mentally superhuman, capable of overpowering the Hulk and the Asgardians that he casually wipes out. Taken as individuals, Thanos is easily overpowered, but with all massed resources on both sides, he is marginally capable of overcoming Ego.
The top argument for Quill supposedly being stronger than Parker is that he's a half-Celestial, being the son of Ego the Living Planet (Kurt Russell); this also explains why he's able to hold the Power Stone with bare hands for as long as he did.
When Ego was killed, Peter Quill lost his connection to the light that gave him powers presented in Guardians of the Galaxy Vol. 2. Even the director, James Gunn, revealed in a now-deleted Tweet that Peter isn't getting those powers back.
It's revealed that Peter Quill's half-Celestial physiology was what allows him to withstand the Stone's power on his own for a brief time before the other Guardians joined with him. They seal the Power Stone in a new Orb and entrust it to the Nova Corps for safekeeping.
Is Thanos a Celestial? Strictly speaking, no. Thanos is not a Celestial. However, he is an Eternal.
Ego was a celestial born outside of the influence of another celestial (i.e. he wasn't born of a celestial seed like the ones we now know are) and thus, lacked the typical physical form of one.
Ah. So Quill doesn't punch Thanos, the Gauntlet comes off, the TVA notices, and the entire timeline vanishes like our hope for the future. Rather than 50% of the universe dead for a few years, everyone is dead forever.
The Celestials debuted in The Eternals #1 (July 1976) and were created by writer and artist Jack Kirby. They reappeared as regular guest stars in three subsequent limited series sequels: The Eternals vol. 2 #1–12 (Oct. 1985–Sept.
Second Pinch Point: Ego finally reveals his plan to Peter when he tells him he intends to take over the universe by physically inhabiting every planet. However, he requires Peter's powers to augment his own.
We know from Guardians of the Galaxy 2 that Celestials are god like beings. Odin seems to possess a power far beyond any other Asgardian. He was a celestial that, unlike Peter's dad, used his power to birth a race of people who each carried a bit of his power within them.
Dormammu isn't a Celestial. He is a Faltine which is a race consisting of beings of extra-dimensional energy born from pure energy. He resides in the Dark Dimension from which he can draw energy to augment his powers.
After all, It's because some fans thought that Galactus is a celestial, but no. Galactus is not a Celestial. Both are considered space gods threatening to destroy the earth. Both are giants with unimaginable power and have very similar wardrobes in the comics.
Unlike his MCU counterpart who ultimately flubbed The Avengers efforts to takedown of Thanos, Peter Quill was able to defeat Thanos in the comics.
She is a member of the Guardians of the Galaxy with empathic powers and is the paternal half-sister of its leader, Peter Quill. Introduced in Guardians of the Galaxy Vol. 2 (2017), she is an alien ward of Ego with the power to control the emotions of people by touch.
In the comics, Thanos is an Eternal, and one from a very important bloodline: His father, Al'ars, was the son of Kronos, who ruled the Eternals of Earth following a civil war that divided the original colony.
