The GN-001 Gundam Exia, commonly known as Exia or Gundam Seven Swords, takes center stage as a mobile suit featured in season one of Mobile Suit Gundam 00. Commanded by Setsuna F. Seiei, this specialized mobile suit is designed for close combat, predominantly armed with melee weapons. Deployed by Celestial Being in AD 2307, the Gundam Exia is one of four Gundams tasked with intervening in global conflicts, aiming to eliminate strife through armed interventions.

These Gundams, with their small numbers, possess overwhelming power and advanced technology that is a century ahead of its time. The semi-perpetual GN Drive at the center of the Gundams provides nearly limitless energy, generating special GN Particles with multifunctional capabilities. These particles grant exceptional mobility, including independent flight, and are utilized for beam weaponry, attitude control, and stealth purposes. The discharged particles can disrupt electromagnetic signals, rendering conventional communication and radar devices ineffective.

The Gundam Exia, like its counterparts, shares similarities with conventional mobile suits, such as the use of E-Carbon for armor material. However, the E-Carbon in the Gundams is reinforced with advanced materials, resulting in higher defensive power. The combination of cutting-edge technology, unparalleled power, and strategic deployment underscores the effectiveness of the Gundam Exia in fulfilling Celestial Being's mission to quell global conflicts.
