The Gundam Throne Drei is the third unit in the Gundam Throne series operated by Celestial Being's second team, Team Trinity. Specializing in supporting the other two Gundam Thrones, Eins and Zwei, the Drei has enhanced search capabilities and unique features like the GN Stealth Field that disrupts radar and communications over a wide area, and a GN Shield Pod for storing equipment for itself and its teammates. Such a support type is not present among the Gundams of the Ptolemaios team, highlighting the different operating method of the three Gundam Thrones that are designed on the premise of fighting together as a team. Due to its role, Drei has minimal offensive power in the form of a GN Handgun and two GN Beam Sabers; it also has a GN Shield for defense. All three Gundam Thrones are developed based on the 0 Gundam, with their systems and armor utilizing the same technology as the Ptolemaios team's Gundams, but they have a different type of GN Drive– the "GN Drive Tau" that emits red GN Particles.
