Technology & Combat Characteristics
To prevent betrayal of powerful GN Drive-equipped machines, such as the Gundams, the Celestial Being developed the "Trial System" that can forcibly take control of machines linked with the organization's quantum computing system, Veda. The Trial System is fitted in the GN-004 Gundam Nadleeh which is concealed within the GN-005 Gundam Virtue, and until the situation calls for it, both the system and Nadleeh will remain hidden.
Development of the Akwos utilized data from the GNY-0042-874 Gundam Artemie, another Gundam fitted with the Trial System and has a pair of special antennas on one of its weapons that can expand the system's range. When fitted with the Akwos, the Nadleeh is called the "GN-004/te-A02 Gundam Nadleeh Akwos". The "te" in its model number stands for "Trial Enhancing", while "A02" stands for "Akwos type unit 02"; unit 01 is canceled while in development and never built. The name "Akwos" is derived from a Navajo word that roughly means "head", and is inspired by the Nadleeh Akwos' most characteristic equipment – the GN Mask Sword. This naming is also in line with the original Nadleeh, which is named after a Navajo spirit.
The GN Mask Sword is the Nadleeh Akwos' main weapon and it also has the Trial System's control functions. Furthermore, it can combine with the suit's GN Shield and then mounted on the suit's back to increase the Trial System's range. There are also four movable "Trial Blade Antennas" on the suit's limbs that serve to expand the Trial System's range. Unlike the Nadleeh, which appears from within Virtue to catch the enemy by surprise, the Nadleeh Akwos is launched as a stand-alone unit. Thus, the other parts of the Akwos equipment are designed to improve the suit's armor, propulsion power, etc. The Nadleeh Akwos is unfortunately never deployed in combat as the Trial System was rendered useless due to the betrayer's capture of Veda.
History
AD 2308. Upon realizing that Alejandro Corner might killed them after they had assisted in the development of the GNX-603T GN-X, Robert Spacey and Deborah Galiena escaped to Lagrange 1's asteroid region. At that time, the pair was unaware that the final battle between the Celestial Being and the UN Forces was going to take place there. When the battle occurred, the pair lay low until the fighting was over. While in the asteroid region, the pair accidentally discovered one of the asteroid bases used by Celestial Being.
In the base, Robert and Deborah met members of Fereshte, a support organization of the Celestial Being. One of the members, a man with a vicious face and wearing handcuffs, revealed that Celestial Being had collapsed after its defeat by the UN Forces, and that Fereshte was recovering spare parts from the Celestial Being's various supply bases. Hearing this, Robert was terrified for his and Deborah's safety. No one would reveal such classified information of a secret organization to others, unless they had planned on killing them later. The handcuffed man continued that despite the Celestial Being's downfall, the members of Fereshte still have to live on and that the collected spare parts would be useful to them in the coming days.
Pointing to a sword with a huge face, the man remarked that it would be a waste to leave such equipment here. According to him, that sword had the ability to control other Gundams. As a researcher studying Mobile Suit development history, this was very interesting to Robert and even worth giving up his life if he could learn all about its history before he was killed. The man explained that the sword was part of the Akwos equipment for the Gundam Nadleeh, and Robert immediately imagined a Gundam he had never seen before using this sword and leading other Gundams.
The man then said that Fereshte had completed their task at the base, and advised Robert and Deborah to leave quickly, otherwise they would never be able to clear their names if the UN Forces arrived. With that, the man left without killing them. Robert and Deborah left as told and vowed not to tell others what they had seen. The pair headed to Earth to look for a journalist in Japan who could help them. Unfortunately, the journalist had passed away and through Deborah's connection, they managed to seek shelter at the Okinawa Base. The UN then learnt of their circumstances, but did not pursue the matter. Robert felt things would have turn out differently if the UN knows about the incident in the asteroid base.
