In the aftermath of the Snap, the Benatar became the primary vehicle used by the Avengers to journey around Earth and travel through space. After the Blip, the Benatar was returned to the newly reassembled Guardians.
Used by the Guardians
After the Milano was severely damaged by a quantum asteroid field and subsequently abandoned on Berhert in 2014, the Guardians of the Galaxy acquired a new ship with an auxiliary pod ship attached, which they dubbed the Benatar. Four years later, the Guardians of the Galaxy received a distress call sent by the Asgardian ship Statesman. They took the Benatar to the location indicated by the distress call in order to rescue its sender, only to find multiple bodies floating in outer space among spaceship debris. However, one Asgardian was still alive: Thor, who fell onto the Benatar cockpit window. Thor was promptly taken aboard the spaceship.
Once Thor was awakened by Mantis, he explained that the Asgardians had been attacked by Thanos and the Black Order. Thor took some time to recover from his ordeal aboard the Benatar but then decided to head to Nidavellir so he could have a new weapon forged to fight Thanos. Thor, along with Rocket Raccoon and Groot, used the auxiliary pod to travel to Nidavellir while the other Guardians left for Knowhere, as they suspected Thanos would go there to take the Reality Stone from the Collector.
The Guardians landed the Benatar in Knowhere's third quadrant. Disembarking, they infiltrated the planet and encountered Thanos, who defeated them and captured Gamora. The Guardians then returned to the Benatar, where Star-Lord attempted to distract himself by playing music, much to Drax's displeasure. They soon realized that they had been left a message by Nebula, who instructed them to meet her on Titan, prompting Star-Lord to fly the Benatar there.
Used by the Avengers
In the aftermath of the Battle of Wakanda, the Snap happened and fifty percent of all life in the universe was gone. The only ones left on Titan were Tony Stark and Nebula, who used the Benatar to leave Titan, laying a course back to Earth. En route it was found that the Benatar’s fuel cells had been damaged during the Battle of Titan. Without a supply of spare parts, however, the two were unable to repair the ship and they were left stranded in deep space. Before the oxygen supply ran out, Captain Marvel, sent by the Avengers, found the ship and brought it to Earth.
When long range sensors had picked up another surge of the Infinity Stones' energy and Nebula revealing the coordinates to the Garden, the Avengers decided to fly there and reclaim the six Infinity Stones in order to reverse the Snap. Rocket Raccoon managed to repair the damages to the Benatar, and co-piloting with Danvers, flew Captain America, War Machine, Thor, Black Widow, Bruce Banner and Nebula to the Garden. After confronting the warlord only to learn he'd destroyed all six stones to prevent anyone undoing his work, Thor decapitated Thanos and walked away, leaving the other Avengers to board the Benatar and fly back to Earth.
As official members of the Avengers, Nebula and Rocket used the Benatar to return to space in order to help other worlds recover from the Snap. Sometime between 2018 and 2023, Rocket returned to Nidavellir and reclaimed the Benatar’s space pod, reattaching it to the main ship. After the Avengers decided to initiate a Time Heist, Nebula and Rocket used the Benatar to return to Earth, landing on the lawn of the New Avengers Facility and accidentally ruining Scott Lang's tacos. The Avengers soon decided to have Thor and Clint Barton rejoin them, and as Romanoff used the Quinjet to travel to Tokyo and recruit Barton, Rocket and Hulk flew the Benatar to Tønsberg in Norway, which had since been renamed New Asgard, to retrieve Thor and fly him back to New York.
The Benatar was then shrunk down via Pym Particles so that Barton could easily carry it on his person. As Barton, Romanoff, Nebula and War Machine were sent back in time to 2014, the Benatar was restored to its normal size so that the four could fly off Earth and to Morag. Upon arriving on Morag, Nebula input the coordinates to Vormir on the Benatar for Romanoff and Barton while the space pod was disengaged for herself and War Machine to potentially use.
Barton and Romanoff sat in the pilot seats of the Benatar enjoying the ride as Romanoff flew them to Vormir, going along the set course. Once they arrived, they landed the ship and disembarked, using the Pym Particles to shrink the ship down once more, with Barton keeping it with him, as promised to Rocket before the mission. After Barton had collected the Soul Stone, he returned to 2023, bringing the Benatar back with him.
Returned to the Guardians
After the Battle of Earth, Barton relinquished the Benatar, which was restored to its normal size and returned to the Guardians of the Galaxy. The Guardians then flew the ship from New York to Tønsberg, Norway in order to retrieve Thor and return to space, with Thor and Star-Lord arguing over who was the ship's captain.
