Jet Boot Attachments are jets that Star-Lord attaches to his boots to hoist him up in the air, after activating them on his leg.
Quill was able to distract Korath and killed his Sakaaran soldiers by using his Plasma Sphere before he then shot Korath with his Quad Blasters. Believing he was now safe, Star-Lord picked the Orb up and made his escape while being chased down by Korath. Star-Lord used his jet boots to pick up speed as he made it to the Milano and used the Gravity Mine again to stop the other soldiers from shooting at him, all while Korath furiously ran closely behind him.
Having taken off his helmet, Star-Lord started up his ship and flew away from Morag while Korath still shot at him from a large canon, forcing Star-Lord to use his flying skills to dodge the blasts. Once he had gotten away from the Kree soldier, Star-Lord confidently began cheering until he accidentally flew into a blast of steam which almost caused him to crash-land until he was just able to regain control of his ship and then continued to make his hasty escape.
Star-Lord went to Xandar in order to sell the Orb, saying goodbye to Bereet before he left. He brought it to the Broker who had made the deal with Yondu Udonta in hopes of selling it to another buyer. The merchant refused to take the Orb after Quill told him that Korath the Pursuer had been working for Ronan the Accuser.
As he was being pushed outside of Broker's Shop, Quill protested Broker's actions before he encountered Gamora was stood outside the shop watching the commotion. Changing his tone, Quill claimed that Broker had quit on a deal and did not have any integrity, like he did. Quill then attempted to flirt with Gamora, introducing himself as Star-Lord while Gamora seemed less than impressed by him, despite calling him a man of honor which Quill agreed with.
While Quill continued to try and flirt with Gamora, he was suddenly attacked and kicked in the chest as Gamora took the Orb from his hand and attempted to get away. Quill quickly used Energy Bolas to trip over Gamora before chasing after her and trying to wrestle the Orb away from her hands. However, Quill quickly found himself being overpowered by the assassin who drew Godslayer and prepared to kill him while Quill was pined down and defenseless.
Refusing to be defeated, Star-Lord distracted Gamora by teaser her while he place one of his Jet Boot Attachments and then activated it, causing Gamora to be sent flying backwards. While Quill celebrated, he was then captured by Groot, only for Gamora to free him by cutting off Groot's arms. Once the bag was opened, Star-Lord used the chance to shoot Gamora with his Quad Blasters and then attempted to escape on foot with the Orb still in his hand.
Quill had kept the Orb with him to ensure that the others did not leave without him as he knew they would not leave the chance to sell it to their buyer and make a large profile, so Quill changed into his own clothes and went on his mission to reclaim his Walkman. Star-Lord fought through all the guards using his Quad Blasters, easily subduing them before they had a chance to fight back. When one of the guards he had knocked down complained about seriously damaging his next, Star-Lord continued walking past him and shot him once again with a blast of electricity, knocking him out while Star-Lord continued searching for his Walkman
Star-Lord proceeded to exit his pod and flew through deep space to reach Gamora, despite all of Rocket's protests that he would not be able to survive in the extreme conditions of deep space. Refusing to listen to Rocket, Star-Lord gave Gamora his mask to help her survive while his own body began to freeze from the extreme cold and lack of oxygen. Before Quill could suffocate and die in space, they were both then surrounded by the Eclector piloted by Udonta.
After Star-Lord's Aero-Rigs were left on Ego during the planet's destruction, he used the jet boot attachments again during the Battle of Titan. However, it was decimated along with Star-Lord after the Snap.
While Peter Quill activates them with buttons on his leg. The jet attachments can rotate in any direction and can be used to propel him through the air at great speed, though they do not allow for sustained flight and only allow him to jump and briefly float for several feet. They can also be used in flying in deep space due to the lack of gravity and weight removing the limitations they experience in environments of normal gravity. Quill improvised the technology as weapons by attaching one of them on a hostile and activated them, which sent the target flying backwards.
