The C-Packs was the third optional equipment for the RX-9 Narrative Gundam and is embellished with Psycho-Frame as additional armor. It is said that no such equipment plan originally existed for the MS, resulting in minimal conversions being hastily applied to the MS. Despite its unusual origin, the MS did achieve its concept to have an increased amount of Psycho-Frame, proving the high extensibility of the Narrative Gundam. This configuration of the MS is also called the "Psycho Package" and the Psycho-Frame used to create it was independently collected by Luio & Co.
The RX-9 Narrative Gundam was deployed in the Phoenix Hunt operation and two optional armaments, the high mobility A-packs, and B-packs with wire-guided assault units were prepared for it. The MS confronted the RX-0 Unicorn Gundam 03 Phenex with each of the armaments but failed to capture it, and both armaments were destroyed in the process. After the battle at Metis, the operation was suspended and it was decided that the Narrative Gundam was to be released from the Damascus. This was when the C-Packs was attached to the MS. The Narrative Gundam C-Packs then headed to its final battle at the Helium-3 storage base,
