In a future era, humanity’s reliance on fossil fuels results in their total exhaustion, triggering an unprecedented energy crisis. In response, the world shifts to solar power as an alternative. Nations consolidate into three major blocs: the Union of Solar Energy and Free Nations, the Advanced European Union, and the Human Reform League. Each faction gains access to a solar generator, providing them with limitless energy.
Consequently, countries that once depended on fossil fuel exports fall into poverty, sparking prolonged wars and internal conflicts over control of solar energy. Into this turmoil emerges an unknown paramilitary group calling themselves "Celestial Being," which aims to eradicate all warfare through armed intervention using mysterious, highly advanced Mobile Suits called Gundams.
Mobile Suit Gundam 00 follows Celestial Being’s Gundam Meisters—Setsuna F. Seiei, Lockon Stratos, Allelujah Haptism, and Tieria Erde. These four plunge into the devastating battles among the three superpowers, striving to achieve their goal of changing the world.
