The Deathscythe, the second of the five Gundams dispatched to Earth as part of Operation Meteor, was created by the scavenger organization known as the Sweeper Group. It was developed by the Sweeper Group's Professor G, an expert in stealth technology. His creation was called the XXXG-01D Gundam Deathscythe, and it proved to be a true mechanical terror when it was launched to Earth to fight OZ during Operation Meteor in AC 195.

"Gundam 02," as the Deathscythe was code-named by OZ forces, was equipped with standard vulcan guns and machinecannons for ranged weapons. The Deathscythe's primary weapon is its lethal beam scythe, supplemented by the standard vulcans and machine cannons. The Gundam's buster shield also functions as a weapon, equipped with sharp pincers and a central beam blade; the shield can even be launched at enemy mobile suits, to deliver its killing blow at a distance. But in order to use these weapons effectively, the Deathscythe was also equipped with a "hyper jammer" ECM system, making the Gundam invisible to various types of electronic sensors, thus making this Gundam ideal for such hit-and-run tactics. The Deathscythe's pilot, Duo Maxwell, became well known as the "God of Death" for his mastery of these stealthy strikes.
