Gundam 00

Five pilots, one impossible mission: end all war, or be destroyed by it.

Gundam 00 is a two-season mecha anime produced by Sunrise that first aired in 2007 and 2008, directed by Seiji Mizushima. Set in the year 2307 of the Cosmic Era timeline, it follows the elite pilot Setsuna F. Seiei and the five members of Celestial Being, a private organization that deploys devastatingly powerful mobile suits to forcibly end the endless cycle of national warfare. The series is celebrated for its philosophical depth, its reimagining of what 'Gundam' means as a concept rather than a machine, and its emotionally intense ensemble cast.

As the 20th anniversary entry in the broader Gundam franchise, Gundam 00 deliberately recontextualized the 'Gundam' name as a title bestowed upon those who fight to change the world, rather than a fixed designation for a particular suit. This conceptual shift, combined with the visually striking GN Drive technology and the series' unflinching look at the human cost of war, made it one of the most discussed and fan-favorite entries in the franchise.

Lore & Background

In the world of CE 2307, humanity has spread across the Earth, the Moon, and orbital colonies, yet the nations and blocs that govern these territories remain locked in perpetual, low-intensity conflict over energy resources and territory. Private military contractors like A-Laws have grown so powerful that they effectively police the weak, and no single government can claim authority over the whole. Into this fractured landscape steps Celestial Being, a shadowy organization whose existence is confirmed only when its mobile suits—each powered by the revolutionary GN Drive, a reactor that generates and disperses a unique particle field—appear on the battlefield with a destructive capability that makes conventional armies look obsolete.

The five pilots of Celestial Being are not soldiers in any traditional sense. They are young people, many of them orphans or former child soldiers, who were raised and trained by the supercomputer Veda for a single purpose: to wield the mobile suits that carry the title 'Gundam.' The title itself is not a model number or a manufacturer's code; it is a designation that Veda bestows upon the one who will carry the weight of changing the world. This philosophical framing elevates the series beyond a simple war narrative into a meditation on what it means to impose one's will on an entire civilization and whether the violence required to stop war is itself a form of war.

The GN Drive technology is central to both the plot and the visual identity of the series. The particles it emits create a distinctive blue-green luminescence around the mobile suits, and the suits themselves feature a sleek, angular design language that departs from the bulkier Universal Century aesthetic. The technology is also the MacGuffin of the story: every nation wants to possess it, and the political machinations surrounding its development drive much of the conflict in both seasons.

In Their Own Story

The Pacific was quiet at 0300, the kind of silence that only exists in the gap between one war and the next. Setsuna sat in the cockpit of the Exia, his fingers resting on the controls without touching them, watching the city lights of a coastal garrison smear into ribbons of amber through the canopy glass. Lockon's voice crackled over the comm, dry and amused, telling him that the A-Laws patrol had shifted two kinks south. Setsuna did not answer. He was thinking about the word Veda had given him—'Gundam'—and how it felt less like a name and more like a wound that never fully closed. The GN Drive hummed beneath his spine, a low thrum he had felt since he was old enough to understand that the world was made of people who would kill each other over a patch of seabed. He pulled the canopy shut. The blue-green glow bled out across the water like a second moon. Somewhere in the distance, a siren began to wail, and the silence broke, and the war that was supposed to be over started again.

Reader's Guide

SETUP — CE 2307 is a world of fragmented sovereignty. Nations, blocs, and private military firms like A-Laws fight over energy resources and orbital territory in a grinding, attritional stalemate. No one wins; everyone bleeds. Celestial Being, a private organization of unknown origin, suddenly appears on the battlefield with mobile suits powered by the GN Drive, a reactor technology that dwarfs anything in conventional arsenals. Their first strikes are surgical and devastating, targeting military infrastructure rather than civilians, and the world is forced to confront the fact that a single small group now holds a power asymmetry no government can match.

ESCALATION — As the series progresses, Celestial Being's campaign intensifies. The five pilots—Setsuna, Allelujah, Lathar, Neils, and Yamato—face not only state militaries but also A-Laws and rival factions seeking to seize GN Drive technology. The political landscape fractures further: some governments attempt to negotiate, others declare the organization a rogue threat, and internal divisions within Celestial Being begin to surface as the pilots' personal histories and loyalties collide. The mobile suits evolve, with Setsuna's Exia combining with a support unit to form the far more powerful 00 Gundam, a leap in capability that reshapes the military balance of the entire conflict.

TURNING POINT — The 'Change the World' operation in the second season marks the series' central pivot. Veda, the supercomputer behind Celestial Being, reveals a broader plan that goes beyond stopping individual wars and instead seeks to fundamentally restructure human civilization. The pilots must decide whether to carry out this plan or resist it, and the distinction between liberator and tyrant becomes razor-thin. The final confrontation pits the 00 Gundam and the remaining mobile suits against a coalition of every military force that has opposed them, in a battle that is as much ideological as it is kinetic.

AFTERMATH — The war ends, but the world it leaves behind is scarred and uncertain. The question of whether violence can ever be the legitimate instrument of peace remains deliberately unresolved, echoing the franchise's long-running theme that the 'Gundam' is not a machine but a choice. The series closes not with a triumphant parade but with a quiet, ambiguous stillness, leaving the audience to sit with the weight of what was won and what was lost.
