Developed by the Celestial Being's Krung Thep engineering team based on the GN-000 0 Gundam, the Gundam Rasiel also uses data derived from the 2nd generation Gundams such as GNY-001 Gundam Astraea. Although not the first 3rd generation Gundam to be developed, it is the earliest to be completed and is deployed in 2302 AD, five years ahead of the other 3rd generation Gundams such as GN-001 Gundam Exia. With its concealed model number, Rasiel is a special Gundam developed upon Veda’s directions; its details are classified as a top secret and known only by selected organization members. Even its maker, Ian Vashti, is also not fully aware of its internal systems.
Named after the archangel Raziel, whose name means ‘secrets of gods’, the Rasiel is powered using the GN Drive previously used by the 0 Gundam. It is developed for gathering data/intelligence in places that requires direct contact, such as the battlefields, which Veda has difficulties with. Thus, it is also known as the ‘Observer of the Battlefields’. Due to its design as a reconnaissance unit, Rasiel does not have high offensive power and consumes less GN particles than other Gundams. Despite this, it has no problem destroying 12 AEU-05/00 AEU Hellion Mediums within 46 seconds. When additional firepower is needed, Rasiel can be supported by the GNR-000 GN Sefer, or combine with it to form the GN-XXX + GNR-000 Sefer Rasiel, which also boosts the suit’s mobility. Like the other 3rd generation Gundams, Rasiel can disperse GN Particles to jam enemy’s rader and communication systems, and also has voice activated Optical Camouflage to hide from its enemies or when its pilot needs to conduct missions on foot. Despite having a GN Drive, Rasiel has no access to the Trans-Am System as it is not unlocked till 2308 AD.
