The Gundam Deathscythe Hell is the upgraded version of the Gundam Deathscythe seen in Mobile Suit Gundam Wing. The suit was redesigned by Hajime Katoki for the movie sequel Mobile Suit Gundam Wing: Endless Waltz. Both versions were piloted by Duo Maxwell.
Like its predecessor, the XXXG-01D Gundam Deathscythe, the Deathscythe Hell is a mobile suit that specializes in stealth and close combat. One of its pilot's, Duo Maxwell, favorite strategies is to use the Gundam's hyper jammers and its "active cloak" system to sneak close to enemy units to catch them unawares. This tactic is usually good for taking out at least one or two enemy units, after which Duo will shut off the active cloak system allowing his Gundam to be seen.
Deathscythe Hell's primary weapon is a beam scythe much like its predecessor. However the new beam scythe has been upgraded from the original by adding a second beam scythe blade and a small rocket engine on the end. The second beam scythe gives the weapon a slightly greater reach while the rocket engine increases the power of the swing allowing Deathscythe Hell to cut through multiple enemy units with ease.
The Deathscythe Hell's secondary weapon is a Buster Shield on the left arm which can launch from said arm to be used as a projectile weapon. The shield has two large metal blades that open just before launch to reveal a beam blade emitter beneath.
Finally to round out its selection of weapons Deathscythe Hell is equipped with a pair of head mounted Vulcan cannons and chest mounted machine cannons but these weapons are rarely used.
In combat Duo Maxwell uses the same fighting style piloting Deathscythe Hell as he did the original, however there is one significant difference. Duo seems in some cases less concerned about dodging enemy attacks. This is probably because Deathscythe Hell is equipped with a set of very durable shoulder shields which are strong enough to block multiple attacks from the beam cannons utilized by the Virgo mobile dolls.
When the XXXG-01D Gundam Deathscythe was captured and destroyed by OZ's forces in AC 195, the extremely durable gundanium-made remains of that mobile suit were taken to OZ's lunar base and mobile suit factory for storage. The five scientists who had built the Gundams plaguing OZ were also at the lunar base, captured and forced to develop new mobile suit technology to secure OZ's rule over Earth and the space colonies. Despite their apparent "cooperation," however, the scientists also began rebuilding the Deathscythe in secret, preparing for the day when captured Gundam pilot Duo Maxwell could return to the battlefield. That opportunity came when the Romefeller Foundation - the political force behind OZ - became split over a number of issues, and the "Treize Faction" of OZ attacked the lunar base, which at the time was still under the control of Romefeller loyalists. During the chaos, Duo managed to escape, taking his rebuilt XXXG-01D2 Gundam Deathscythe Hell to continue fighting on his own. At that time, the Deathscythe Hell was only seventy percent complete; later repairs and field upgrades would allow Duo to complete the resurrected mobile suit, bringing it up to its full combat potential.
The new Deathscythe Hell was a considerable improvement over its original form, with a more powerful twin beam scythe (which mounted a small rocket engine to give it more force when swung against multiple targets), increased speed and mobility to help it maneuver effectively in space, improved hyper jammers, and an "active cloak" system which served as both a optical/visual cloaking system (making the Gundam literally invisible to an enemy's naked eye) and as an external layer of beam-deflecting armor. These improvements allowed Duo to continue his fight against both the militaristic OZ and the radical civilian "White Fang" rebels, putting the Gundam Deathscythe Hell on an almost equal footing with White Fang's newest AI-controlled mobile dolls.
