Deathscythe, the creation of Dr. G., was created like the other gundams for Operation Meteor. Duo Maxwell tried to self-destruct Deathscythe but was stopped by Dr. G. G confronted Duo and told him to steal the Gundam, go to Earth, and fulfill the mission as he saw fit and so this mighty moble suit gained a pilot.

Since the Gundam Deathscythe relies on short-range weapons, it's designed to dash towards its targets at high speed and therefore has the highest speed ability of the five gundams. An improved version of the original Gundam Deathscythe, Deathscythe Hell was adapted for space combat. Its "active cloak" uses the same defensive technology as the Mercurius's planet defenders and doubles as a maneuvering system; when opened, it bears an intimidating resemblance to a devil's wings. The hyper jammers and beam scythe have also been upgraded, and the beam scythe now has a double-beam blade. Later, it was again improved and so became Deathscythe Hell Custom. This version features a new-and-improved, radar-absorbing, beam-deflecting "active cloak" which not only enhances its stealth features but protects it from enemy fire as well. Its main weapon, the beam scythe was also upgraded again, returning to a single-beam blade.

Beam Scythe: Normally retracted, it is stored on the gundam's rear skirt. This weapon can cut an enemy in two with a single stroke. The heat and magnetic fields created by the beam are enough by themselves to begin disintigrating the target as the blade approaches.

Mounted Vulcan: a gun located on the back of the gundam.

Hyper Jammers: The nozzles protruding from the back of the gundam scatter jamming particles which scramble the enemy's radar and cameras allowing it to sneak up on its target.
