Technology & Combat Characteristics
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. 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.
As the Gundam Thrones are customized version of the same basic machine, they have the same body frame and basic parts, with variations in weaponry, equipment and head design setting them apart. The most distinctive feature of the Eins' head is the huge blade antenna located at the top. The torso-mounted GN Drive Tau also serves as the body's central unit with the other body parts placed around it. Additionally, Eins is the only Gundam Throne to have additional optional equipment, namely the "Turbulenz" flight unit that grants high mobility and the ability to transform into Flight Form.
Alejandro Corner, a United Nations ambassador and a Celestial Being observer, masterminded the creation of Team Trinity and Gundam Thrones without informing Celestial Being, with the machines secretly built by Laguna Harvey in the factories within the Orbital Elevators based on his instructions. However, Alejandro's intention was not to help the organization, but to further his and his family's ambition of world domination. The Corner family also developed the GN Drive Tau, based on data of the original GN Drive stored in a purple Haro recovered from a wrecked Celestial Being spaceship near Jupiter. The GN Drive Tau is functionally identical to the original GN Drive, but does not operate semi-perpetually, instead it requires input of electrical energy to function and produce GN Particles. Hence, the GN Drive Tau has limited operating time, affecting the Gundam Thrones' operations. As with the Ptolemaios team's Gundams, the Gundam Thrones have a pair of special antennas for controlling GN Particles, but they are located on top of the shoulder armor (next to the GN Beam Sabers' storage racks) instead of being torso-mounted. Analysis of the recovered remains by Union's Iris Corporation concluded that the self-destruction is to safeguard power-related technology as all power system parts are destroyed. The Eins' operating data and weapon technology are later utilized by the UN Forces to develop the Cannon variant of the GN-XII.
History
The three Gundam Thrones operated by Team Trinity first appeared during the battle in the Taklamakan desert, with Johann Trinity using the Eins' GN Launcher to rescue Gundam Virtue and Gundam Dynames from enemy forces. After the battle, Celestial Being observer Alejandro Corner held an emergency meeting with fellow observers on whether to accept the Team Trinity into Celestial Being. The meeting ended with unanimous approval.
Later in space, Johann carried his two siblings on the Eins' hands as they left their mothership to meet the Ptolemaios team on board the Ptolemaios. While Team Trinity chatted with the other Gundam Meisters and Sumeragi, the Eins was inspected by Ian. Ian later reported that the Gundam Thrones utilized a different type of GN Drive with limited operating time and the Ptolemaios team suspected a traitor within Celestial Being.
The Gundam Thrones launched a series of aggressive armed interventions around the world, annihilating military bases and even civilian operated weapons factories. Two most notable attacks were the destruction of a Union MSWAD base with the Eins' GN Mega Launcher, killing Professor Ralph Eifman, and Eins' assault on Iris Corporation's weapons factory that resulted in the death of over 800 civilians. The attack on Iris Corporation was interrupted by the arrival of Graham's Union Flag Custom, which managed to captured one of Eins' GN Beam Saber and used it to cut off the Gundam's right arm, forcing it to retreat.
The Team Trinity's indiscriminate attacks eventually resulted in a fight against the Ptolemaios team's Gundam Meisters. During the battle, Eins and Drei engaged Gundam Virtue, while Zwei was busy with Gundam Exia. Elsewhere, Alejandro noted to his accomplice, Ribbons Almark, that the fight occurred earlier than expected. Eins and Drei were later disabled by the Trial System when Virtue changed into Gundam Nadleeh. However, Ribbons forcibly disengaged the system through Veda, allowing the two Gundam Thrones to resume operation. Soon after, Gundam Dynames joined the battle and Johann ordered the Team Trinity to withdraw, noting that Gundams destroying each other would hinder Celestial Being's plan.
The Gundam Thrones' reign of terror ended when the traitorous Alejandro provided the world's three major powers with 30 GN-Xs and GN Drive Taus to power these machines. Using 10 of the GN-Xs, the HRL stopped the Gundam Thrones' assault on one of its base. Team Trinity then stopped receiving instructions from their handler, Laguna Harvey, and not long after, their African base was attacked by HRL's GN-X team. Despite using the Eins' GN High-Mega Launcher, Team Trinity only took out one of the GN-X. The Gundam Thrones then engaged the remaining GN-Xs and somehow escaped. On the run and low on GN Particles, the Team Trinity encountered the HRL's GN-X team again, and managed to flee after Eins fired its smokescreens.
With Team Trinity's usefulness almost at an end, Alejandro decided to finish them off. The Team Trinity ran to an island in the Atlantic Ocean and later encountered Ali al-Saachez who was hired to kill them. Ali immediately killed Michael Trinity and stole Zwei. Using Eins, Johann engaged Ali's Zwei. During the fight, Ali revealed that Johann and his siblings were sacrificial lambs. Despite his best effort, Johann was no match for Ali, and died when the Eins exploded after receiving multiple shots to its back. The remaining member of Team Trinity, Nena Trinity, was saved due to the arrival of Exia.
