Guardian Corps

The Guardian Corps is an organization on Cocoon in Final Fantasy XIII. It is a military department of the Sanctum, tasked with more domestic issues compared to PSICOM. As revealed in the Final Fantasy XIII Ultimania Omega, Nao Ikeda, who designed most of the game's support cast, designed the Corps with more color to contrast to the PSICOM uniforms, which are mainly black.

The Guardian Corps is the branch of the Sanctum military responsible for maintaining peace and stability within Cocoon.

''Within their assigned jurisdictions, the soldiers of the Guardian Corps fulfill the role of police officers and protectors, working to eliminate all manner of criminal activity as well as rampaging wildlife. As a unit that works alongside the general population, it rarely employs heavy weaponry or cruiser-class airships. However, the Corps does retain squads of highly mobile shock troops.''

Story
A counterpart to PSICOM, Guardian Corps soldiers are often assigned to protect citizens and secure cities during times of strife. In the days before the main events of Final Fantasy XIII, Guardian Corps regiments investigated the town of Bodhum and the nearby Pulse Vestige, as the Sanctum was concerned about Pulse "infection".

Lightning, a member of the Corps, talked with her leader, Amodar, about the mystery surrounding the Vestige. PSICOM units had been called in to survey the area, piquing Lightning's interest. Amodar warns her not to delve into the matter and instead asks about her family and encourages her to watch the fireworks. Later, Guardian Corps soldiers begin the Purge of Bodhum, commanding anyone in the vicinity to board trains and depart Cocoon for Pulse.

Guardian Corps agents are absent during the Purge incidents at Hanging Edge, where it is made apparent the Sanctum does not merely wish to escort supposedly tainted individuals, but eliminate them altogether. PSICOM units engage in open warfare with Purgees and the resistance front NORA. When Lightning and Hope reach Palumpolum, PSICOM commander Yaag Rosch cooperates with Guardian Corps units to secure the city and hunt down the two l'Cie. When some Corps members protest against Rosch's methods of herding citizens around and shooting suspicious individuals on sight, he reminds them that the l'Cie are dangers to Cocoon.

After Cocoon has been crystallized by Ragnarok Guardian Corps soldiers are seen helping evacuate the citizens. In Final Fantasy XIII-2 it is revealed that immediately following the catastrophe, the Guardian Corps took control from the Sanctum, Cocoon's governing body. A provisional government was formed, consisting primarily of military personnel. This was spearheaded by the Cavalry, an elite unit of the Guardian Corps. Seeking to rebuild society on the strength of human science and free from dependence on the fal'Cie, they founded an institute called the Academy and slowly the provisional government transferred authority to this new organization. The responsibility for defending the populace from Gran Pulse's hostile creatures passed to the institute, and drawing on personnel from the former Guardian Corps, the Academy Security Regiment was born.
