- "I thought your thing was a sword?"
"We've been hired to stop an inter-dimensional beast from feeding on those batteries and I'm going to stop it with a sword?"
"It's just... swords were your thing and guns were mine, but... I guess we're both doing guns now. I just didn't know that."
- ―Star-Lord and Gamora
When Gamora pursued Peter Quill on Xandar, she was interrupted by Rocket Raccoon and Groot, and used the Godslayer to defend herself from the pair, amputating Groot's arms when he attempted to restrain her. While imprisoned in the Kyln, the blade was confiscated by the Nova Corps, but Gamora eventually reclaimed it after escaping from the prison with Quill, Rocket, Groot, and Drax the Destroyer.
The Godslayer was presumably destroyed on Knowhere by Thanos, who effortlessly broke the blade before kidnapping Gamora. However, this turned out be an illusion created by the Reality Stone. The weapon was then collected by Quill.
The Godslayer is capable of cutting through even the most durable of metals, and uses a unique energy core located in the hilt to lower the weight of the blade, making it easier for the wielder to handle. The detachable knife can be used as a melee or throwing weapon.
