Godslayer

Godslayer is the sword of the Galaxy-Class Killer and Guardian of the Galaxy, Gamora.

History
Godslayer was given to Gamora as a gift by her adopted father, the galactic overlord Thanos. During her youth, she trained under the tutelage of Ronan the Accuser, and Godslayer grew to become her favorite weapon.

When Gamora pursued Peter Quill on Xandar, she was interrupted by Rocket Raccoon and Groot, and used Godslayer to defend herself from the pair, amputating Groot's arms when he attempted to restrain her. While imprisoned in the Kyln, Godslayer was confiscated by the Nova Corps, but Gamora eventually reclaimed it after escaping from the prison with Quill, Rocket, Groot, and Drax.

During the Battle of Xandar, Gamora dueled Nebula using Godslayer, and emerged victorious.

Capabilities
Much like the sword of the Asgardian Lady Sif, Godslayer has a retractable blade. It is capable of cutting through even the most durable of metals, and utilizes a unique energy core located in the hilt to lower the weight of the blade, making it easier for the wielder to handle.

Trivia
