The GN-001 Gundam Exia (aka Exia, Gundam Seven Swords), is the close combat Gundam-type mobile suit featured in both seasons of Mobile Suit Gundam 00. The unit is piloted by Setsuna F. Seiei.

Technology & Combat Characteristics
A 3rd-Generation Gundam, Exia is designed to be a close quarters combat (CQC) type mobile suit (MS). The unit is the successor to GNY-001 Gundam Astraea and one of the predecessors to GN-0000 00 Gundam. Much of Exia's design was heavily influenced by the Astraea Gundam. What this means is that even though Exia's weapons are specialized for CQC, its basic performance is still that of a general purpose mobile suit. This is mostly evident as Exia is the only Gundam out of the four main 3rd Generation units that retain a MS frame that has human-like range of motion. The lack of this range of motion on the other three units is not considered a weakness but rather because it was deemed unnecessary.

Gundams (and by extension other GNMS) benefit from the weight reducing effects of GN Particles, and this effect can also be used for weight alteration of various body parts. Because of this, the pilot can freely control the suit's inertia, influencing maneuverability when it is in the airborne. In space, this ability is transformed into Active Mass Balance Auto Control (AMBAC). As such, the legs actually never need to "walk" when moving.
