Reunited with the Guardians, Star-Lord continued adventuring the galactic super-team. Groot was now a modestly grown teenaged plant-boy, and the group found themselves with a new ship, the Benatar, named after the '80s rock star and one of Quill's childhood favorites. Years after the battle with his father Ego, the Guardians Of the Galaxy receive a distress call from an Asgardian refugee ship, the Statemsan. Carrying the entirety of the surviving Asgrardian people after Ragnarok, it was attacked by the Mad Titan Thanos, who was in search of the Space Stone, taken from Asgard by Loki.
Coming upon its wreckage, Star-Lord and the Guardians discover only Thor alive. Filling them in, Quill and his team learn that Thanos is on the verge of assembling all six Infinity Stones, and needs their help to stop him. Rocket, Groot, and Thor head to Nidavellir, where they will fashion Thor a weapon capable of killing Thanos, while Quill, Mantis, and Drax join Gamora in hunting for her father. They find him on Knowhere, where he has already collected the Reality Stone, but fail to stop him, as he escapes to parts unknown ... but takes Gamora, favorite daughter — and Quill's girlfriend — with him.
Now, Quill is determined to find Thanos and rescue Gamora. But he may need help if he's going to succeed.
