After the Snap, Tony Stark and Nebula resorted to the Benatar in hopes of returning to Earth and reuniting with the Avengers. The Benatar only had a few supplies left since Stark and Nebula had been on the ship for more than twenty days. Emaciated from lack of food and water Stark recorded a message using his helmet for Pepper Potts explaining that he'll miss her in case he died in space. Afterwards, Stark drifted off to sleep as Nebula sympathized for him.
Shortly after Tony Stark started drifting off to sleep, he was awakened by a blinding light emitted from Captain Marvel traveling through space. After Captain Marvel found Stark and Nebula aboard the Benatar, she brought it back to the New Avengers Facility on Earth. In the middle of the field, Stark exited out of the ship and was reunited with Steve Rogers, Pepper Potts, and the rest of the Avengers left after the Snap, while Nebula comforted Rocket Raccoon on the steps of the Benatar.
At the New Avengers Facility, the remaining Avengers conversed about the possible location of Thanos. When Steve Rogers asked Tony Stark if he had any indications of where Thanos could be, Stark erupted and told Rogers that he had no information. Stark then confronted Rogers, explaining that his attempt to build a suit of armor around the world was to prevent the very situation they were in. After the sedative Stark had passed out and rested due to his long duration in space, the remaining Avengers found Thanos on Planet 0259-S and flew there in the Benatar, only to realize the Infinity Stones had been destroyed.
