GN Field is a shielding technology in Mobile Suit Gundam 00 developed by Celestial Being and later copied by the Innovators and A-Laws.


The GN Field is a defensive shielding technology developed by Celestial Being. While developing their second generation Gundams, Celestial Being engineers were trying to figure out a way to give their Gundams full defensive coverage using condensed particle fields and this technology was first tested on GNY-004 Gundam Plutone. A perfected GN Field technology was later used by the GN-005 Gundam Virtue, and eventually applied to Celestial Being's other Gundams, ships, and mobile armors.

The field is created by concentrating enough GN particles within a local area of space. The GN particles can then be shaped and focused into a spherical form for full defensive coverage over the unit(s); however, the field itself is not restricted to spherical forms and can wrap around any shape or size. When the GN particles concentrate enough, the particles become dense enough to resist intense temperatures, physically repel and/or stop ballistic weapons and particle beams.

The strength of the field seems to be reflected by the particle's color intensity. The brighter and thicker the particles over the unit, the stronger the field seems to be. Depending on the strength of a particular field, it may or may not be penetrated by ballistic attacks.[1][2]

While the field provides considerable defense against most attacks, it can be overwhelmed by an opposing particle beam that is stronger than the field. The characteristics of the GN Field can be affected by its GN Particles' compression rate, and beam shots can penetrate the barrier if they match this compression rate.[3][4][5] In addition, repeated powerful beam attacks on a single section of the field may also cause the section to be penetrated.[6] This suggests that GN Fields suffers cumulative damage/deterioration after each attack, if the field cannot replenish GN Particle counts and maintain field's particle density fast enough.

The main weakness of GN Fields are their inability to stop solid objects that are enveloped with GN particles. This vulnerability lead to the inclusion of Exia in Aeolia Schenberg's plan, as a countermeasure against rogue Gundams.[7] While GN Blades are commonly used to attack units protected by a GN field, the tips of GN Missiles can also achieve the same effect. GN particle-enveloped objects cancel out the defensive properties of the GN Field at the point of contact and allows the object to penetrate the opposing GN Field, regardless of field strength.

The GN Field is also an important mechanism for the GN Composite Armor, since the armor works by generating a GN Field in the interior spaces of the suit's armor.[8] If the outer physical layer of the armor is destroyed by an attack, the GN Field can still strongly protect the inner physical from the damage.[8]

In addition, GN Fields can also be used to envelope a section of a melee weapon, improving its capabilities. Eventually Celestial Being engineers also learned to manipulate GN Fields for other offensive purposes. By controlling the formations of the field, it can be used as a focal point to fire more powerful particle beams. The overall aspects of the technology was later taken by the Innovators and shared with the A-Laws to create more formidable adversaries against Celestial Being.



While the more general "GN Field" technology have existed ever since the days of the 0 Gundam for usage in shields,[9] the development of the "outer spherical" GN Field was first attempted on the second generation GNY-004 Gundam Plutone as a first option. However, the system then was imperfect and have trouble maintaining a stable GN Field.[8] However, work on improving the system continued, and a perfected version was installed on Plutone's successor, the GN-005 Gundam Virtue. During Plutone's development, the GN Composite Armor, which generates an internal GN Field within the suit's armor, was created as a backup option for the "outer spherical" GN Field.[8]

  • The GN Field bears a resemblance in both appearance and function to Primal Armor from the Armored Core 4 and Armored Core 4 Answer series.
