While cruising in space with the Benatar, 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 left with the pod of the Benatar with Rocket Raccoon and Groot 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 and indeed encountered Thanos, who defeated them and captured Gamora. They were then contacted by Nebula, who instructed Mantis to meet her on Titan. Therefore, the Guardians took their spaceship to Thanos' homeworld in order to stop him and release Gamora.
After the fight with Thanos was lost, the Decimation happened and 50% of all life in the universe was gone. The only ones left on Titan were Tony Stark and Nebula. They took the Benatar and left Titan.
- The Benatar is named after American singer and songwriter Pat Benatar.
