The Gundam Throne Eins is the first of three Gundam Thrones operated by the Celestial Being's second team, Team Trinity. The Gundam Thrones are customized version of the same basic machine, with Eins designed for high-power, long-range bombardment using its huge GN Launcher; this can be thought of as a combination of the long-range shooting function of the Gundam Dynames with the artillery warfare capabilities of the Gundam Virtue. However, Eins is not based on these two Gundams, instead it was developed using the technology of the 0 Gundam. The GN Launcher has two more powerful firing modes when Eins connects to and receives GN Particles from the other Gundam Thrones, Zwei and Drei. Besides serving as a fire support unit, Eins is also capable of mid-to-close range combat with its GN Beam Rifle and GN Beam Sabers. It also has a GN Shield for defense. While the Gundam Thrones' systems and armor use the same technology as the Gundams of the Ptolemaios team, they are equipped with a different type of GN Drive– the "GN Drive Tau" that emits red GN Particles.
