A Real Kick In The Crotch
Later, the surviving Avengers and Guardians worked together to snatch the Infinity Stones from throughout time and used them to bring everyone who had been erased back to life. Quill and the others found themselves still on Titan, but began making their way to Earth thanks to Doctor Strange's magic.
Star-Lord flew into battle against Thanos' forces, blasting away at the enemies. During the fight he was saved by an unexpected encounter with Gamora from the past. When he tried caressing her, she kneed him in the crotch twice and went off to continue fighting alongside the modern-day Nebula. The battle ended when Iron Man gained control of the Infinity Stones and used them to snap past Thanos' forces away, leaving the status of Gamora from that time a mystery.
The Never-Ending Mission
After attending Tony Stark's memorial service, Quill and the Guardians agreed to let Thor travel with them, answering distress calls and helping those in need. He also kept an eye out for any more information about Gamora from the past. The Asgardian's tenure with the team ended when Gorr, the God-Butcher began to truly make his presence felt. Star-Lord and the Guardians dedicated themselves to responding to as many pleas for help as possible while Thor and Korg went to assist Sif. Before parting ways, Peter told the Odinson to get out there and find something or someone to love and fight for.
At some point down the line, Peter and the Guardians purchased Knowhere from the Collector, who left the floating Celestial head after his encounter with Thanos during the Infinity War. Quill dedicated his efforts to repairing the damage done to the place so the citizens could carry on living there, an effort aided by the locals as well as the Guardians.
An Alien For Christmas
Having heard Kraglin recount a story of Peter's childhood and his love of Christmas, Drax and Mantis decided to travel to Earth and bring back his hero, actor Kevin Bacon. They also picked up a lot of decorations, which everyone used to bring some holiday cheer to Knowhere. Quill loved the initial sentiment, but was not pleased when he realized they had kidnapped Bacon and altered his mind with Mantis' powers. Though he asked Kraglin to return the actor to Earth, Bacon stuck around after hearing how important his movies had been to Quill.
Bacon did go back home, but after sharing a special Christmas song. During the gift exchanging portion of the festivities, Quill gave Groot a Gameboy and received a piece of art from the walking tree in return. Peter received an even better gift shortly after when Mantis revealed that she was his half-sister. Quill was delighted to find out he was actually related to someone in the family of misfits he had built for himself.
