The Gundam Exia: Complete Guide to GN-001, the GN Drive, and the PG Masterpiece
Development history, GN Drive technology, the Seven Swords system, Setsuna F. Seiei, and why the PG model captures the machine's story through light.
The KOSMOS LED System activates the GN particle flow Bandai built into the PG Exia at every structural level
The GN-001 Gundam Exia is the protagonist mobile suit of Mobile Suit Gundam 00 — the first Gundam series set in a near-future Earth where three power blocs control global energy through orbital elevator networks. Into this setting arrives Exia: a machine that fights with blades, runs on perpetual energy, and represents the opening move of a paramilitary organization attempting to end war by force.
This guide covers the Exia from all angles: its development lineage, its unique GN Drive technology, its seven weapons, its pilot, and why the Bandai PG 1/60 scale version is one of the most technically ambitious Gundam model kits ever produced.
The World of Gundam 00: Why the Exia Exists
Mobile Suit Gundam 00 is set in Anno Domini 2307 — a near future where the depletion of fossil fuels has reshaped geopolitics. Three superpowers control global energy through orbital elevators that beam solar power to Earth: the Human Reform League (HRL), the Advanced European Union (AEU), and the Union of Solar Energy and Free Nations.
This energy monopoly maintains a fragile, permanent cold war. Into this world emerges Celestial Being (天人组织) — a private paramilitary organization with access to technology far beyond any nation. Their strategy is paradoxical: end war by intervening militarily in any armed conflict, regardless of political alignment, using four third-generation mobile suits powered by GN Drive technology no nation can explain or replicate.
The Exia is the machine that announces Celestial Being's existence to the world.
Development History: The Third Generation
The GN-001 Gundam Exia is the third-generation descendant of a development lineage stretching back to Celestial Being's foundational research. The GNY-001 Gundam Astraea (second generation) established the platform architecture from which the Exia evolved.
The four third-generation Gundams were developed in parallel, each specialized for a different combat role:
| Gundam | Pilot | Specialization |
|---|---|---|
| GN-001 Exia | Setsuna F. Seiei | Close-quarters melee combat |
| GN-002 Dynames | Lockon Stratos | Long-range sniping |
| GN-003 Kyrios | Allelujah Haptism | Aerial mobile combat |
| GN-004 Virtue | Tieria Erde | Heavy weapons / particle cannon |

The GN Drive: Perpetual Energy
The GN Drive (太阳炉 — literally "solar furnace") is the most significant piece of technology in the Gundam 00 setting. It is a perpetual energy device: it produces GN particles continuously without fuel input. The production process cannot be replicated by any known scientific method outside Celestial Being, making the Gundams effectively impossible to produce without access to the Drive.
GN particles serve multiple functions across the machine:
- Power generation — continuous particle output powers all systems
- Propulsion — GN particle field enables high-speed flight in atmosphere and space
- Beam weapons — GN particle rifle and cannon fire
- GN field — defensive particle barrier deflecting projectiles and beams
- Optical camouflage — GN particle diffusion enables visual stealth at low energy states
The GN Drive Belt: Visualizing Energy Flow
What makes the Exia architecturally unique among Gundam 00 machines is its GN particle drive belt system. The PG-scale model makes this explicit: translucent cables run through the skeleton from the GN Drive outward to the limbs, capacitors, and weapons systems — representing the particle routing architecture in physical form. In the PG 1/60 model, Bandai recreated this flow path as a structural element of the skeleton that glows when illuminated.
The Seven Swords: Close Combat Doctrine
The Exia's combat role is defined by seven weapons — all melee or near-melee systems, each coated with GN particles to penetrate particle shields:
| Weapon | Type | Function |
|---|---|---|
| GN Sword | Physical blade / rifle | Primary weapon; folds to Rifle Mode for close-range beam fire |
| GN Long Blade | Physical long sword | Extended reach; GN particle edge cuts through GN fields |
| GN Short Blade | Physical short sword | Secondary melee; throwable |
| GN Beam Saber ×2 | Beam saber | Standard beam melee, dual-wield capable |
| GN Beam Dagger ×2 | Beam dagger | Low-energy throw weapons |
| GN Shield | E-Carbon shield | Physical + GN field layered defense |
Special Systems
Trans-Am
Trans-Am releases all compressed GN particles in the Exia's capacitors simultaneously. The effect: three-fold performance increase across all parameters (speed, power, output) for a limited duration. The visual signature is a shift from green to red particle glow and a visible energy trail. After Trans-Am expires, the Exia enters a performance-degraded state until particles recharge.
Optical Camouflage
At low particle output, the Exia can diffuse GN particles around its surface to become visually invisible. The system cannot sustain camouflage during high-intensity operations but enables approach and observation undetected.
The PG 1/60 Gundam Exia Model: Why This Scale Matters
Bandai's Perfect Grade line represents the highest engineering tier in commercial Gundam model production. The PG Exia's defining feature is not its scale or articulation, but its GN particle flow visualization:
- ✓ The internal skeleton is built around the drive belt routing system — translucent cables run through structural members from the GN Drive out to every limb
- ✓ LED mounting positions are pre-formed into the skeleton at every key GN emission point
- ✓ External armor panels are designed to allow GN light to pass through at specific locations
- ✓ The GN Drive unit has a rotation mechanism that creates the spinning luminous effect from the anime
This is a model designed, from the engineering stage, to be lit. The KOSMOS LED kit is the tool that activates what Bandai built into the kit's architecture.

Q: What is the GN Drive in Gundam Exia?
The GN Drive (太阳炉) is a perpetual energy device that produces GN particles without fuel. It powers all of the Exia's systems, weapons, and particle-based abilities. The Drive's glow — visible through the chest armor — represents the machine at operating state.
Q: Who pilots the Gundam Exia?
Setsuna F. Seiei, the protagonist of Mobile Suit Gundam 00. He is Celestial Being's specialist in close-quarters armed intervention.
Q: What does Trans-Am do in the Exia?
Trans-Am releases all stored GN particles at once, tripling the Exia's speed and power for a short period. The machine's color shifts from white to red-orange during Trans-Am. After it ends, the Exia enters a performance-reduced state while particles recharge.
Q: Why does the PG Exia have translucent cables in the skeleton?
These are the GN drive belt representations — physical renderings of the GN particle routing paths from the GN Drive to the extremities. Bandai built them into the PG skeleton to visualize the particle flow narrative from the series. They are designed to be illuminated.
Q: What makes the GN Sword different from a regular beam saber?
The GN Sword is a physical blade (not a pure energy beam) coated with GN particles. This allows it to cut through GN particle defensive fields — which deflect standard beam weapons. It also converts to a rifle mode for close-range beam fire.
Q: What other Gundams use the GN Drive technology?
In the first season of Gundam 00, only the four third-generation Gundams (Exia, Dynames, Kyrios, Virtue) use genuine GN Drives. Other factions later develop mass-produced GN Drive Tau systems — imitation drives with limited output.
Q: Is the name "Exia" meaningful?
The name derives from the Greek word exousia, meaning authority, power, or dominion — the same root that names the "Exousia" class of angels in Christian angelology, corresponding to the Principalities or Powers. All of Celestial Being's Gundams are named for angelic ranks.
