GNW-001 Gundam Throne Eins

The GNW-001 Gundam Throne Eins (aka Gundam Throne Eins, Throne Eins, Eins) is a mobile suit introduced in season one of Mobile Suit Gundam 00 and piloted by Johann Trinity.

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.

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. This enhances its communication capabilities, enabling it to serve as a commander unit for the Team Trinity and strengthens its data link with Drei during bombardments. When compared to the other Gundams, the Gundam Thrones have a peculiar silhouette and this is due to the GN Drive Tau being integrated as part of their main frame to reduce weight. The torso-mounted GN Drive Tau also serves as the body's central unit with the other body parts placed around it. Among the Gundam Thrones, Eins and Zwei have the same cockpit layout while Drei's differs slightly. 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. The inferiority is caused by the inability to recreate the original GN Drive's special core component, the GN Drive Tau is however easier to produce. Unique to the Gundam Thrones' GN Drive Tau is an onboard starter mechanism not present in subsequent GN Drive Tau-powered machines.

Like the green GN Particles from the original GN Drive, the GN Drive Tau's red GN Particles are multifunctional and can be utilized in beam weaponry, for stealth purposes as the discharged particles can cause disruption of conventional communication and radar devices, etc. The red GN Particles are generally safe but have a toxic effect when utilized as beams, causing cellular defects that prevent the application of regeneration treatment to injury site, and this is due to the particles' compression rate. 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. Unlike the Ptolemaios team's Gundams, the Gundam Thrones do not have cables for transporting GN Particles to each part of the body, instead the particles flow within the body's frame structure. Thus, when the coating on the frame's surface is stripped away, a luminescence effect due to the particles within can be observed. The same system is also adopted in the cockpit's frame.
