Technology & Combat Characteristics
This mysterious mobile fighter serves as the commander of the Death Army's aerial forces. In its bird-like Attack Mode, the Gundam Heaven's Sword can soar through the air, use its powerful claws to carry out hit-and-run attacks on ground targets, bombard its foes with feather-like darts, or flap its wings to create tornadoes and firestorms. The Gundam can also transform into a humanoid Standing Mode, allowing it to use kicking attacks like those of Neo Italy's Neros Gundam. During the final fight, it displayed the ability to absorb the power of the God Gundam's Bakunetsu God Finger, causing the machine to turn red and enhance its power even more as well as its ability to regenerate thanks to its DG Cells.
History
As the 13th Gundam Fight continued, the JDG-00X Devil Gundam created Four Heavenly Kings for its protection: GF13-001NHII Master Gundam, Grand Gundam, Gundam Heaven's Sword, and Walter Gundam. The Gundam Heaven's Sword first appeared when all 4 Heavenly Kings attempted to stop Domon Kasshu from reaching the Gundam Fight finals on time. The Gundam Heaven's Sword appeared again during the finals when Domon was fighting with Michelo Chariot's GF13-055NI Neros Gundam. Domon barely managed to repel Michelo, by stabbed the Gundam's eyes, causing Michelo to fly into a rage. Then Michelo's Gundam would morph into the Gundam Heaven's Sword piloted by a vengeful and DG Cell-infected Michelo using a smokescreen created by its explosive transformation, it obscured itself from the audience and to hide itself from Domon, but was ultimately defeated.
The Gundam Heaven's Sword appeared one last time during the Battle Royale on Lantao Island, to try and defeat Domon once and for all, and initially overwhelmed Domon. However Domon was aided by Argo Gulskii and Sai Saici, and they managed to destroy the Gundam Heaven's Sword by using their ultimate attacks in Hyper Mode.
The wings and talons of the Gundam Heaven's Sword would be incorporated into the Grand Master Gundam following the Devil Gundam's final resurrection.
