This gundam paper model is a SD GX-9900-DV Gundam X Divider (aka Gundam X Divider, X Divider), a custom modified version of a GX-9900 Gundam X in the After War Gundam X, the papercraft is created by gpgerbera04, and shared by yenc. GX-9900-DV Gundam is initially piloted by Garrod Ran, but is later piloted by Jamil Neate after Garrod traded-up for GX-9901-DX Gundam Double X.
Gundam X Divider was developed from Gundam X by Kid Salsamille. The unit suffered a devastating defeat against the Bertigo and the majority of its equipment was heavily damaged beyond repair. Kid decided it was a good opportunity to give Gundam X a make-over, using a collection of spare parts as well as salvaged equipment he collected over the years. After he completed all major repairs and enhancements, he re-dubbed it as GX-9900-DV Gundam X Divider, after its new shield.
The only weapons Gundam X Divider kept was the fixed armament of its Vulcan cannons mounted in its torso, but the rest of its armaments were destroyed or replaced following its battle with the Bertigo. The destroyed Satellite Cannon was replaced with an X-shaped flight pack, which allowed storage for: two beam sabers, pylons for extended flight capabilities, and a storage attachment for its new Divider Shield. To replace the destroyed buster rifle and shield of the Gundam X, Kid Salsamille used a pair of battleship-grade beam machine guns. This gave the X Divider a higher rate of fire, as well as a more powerful rifle.
An experimental shield, the Divider, was purchased by Kid and left in his stockpile of spare parts; it was put into use for the X Divider. The shield could be mounted to the back of the Gundam and its thrusters used for flight, the Divider can be hand-held for the same purpose; it can be used for horizontal thrust to propel itself while shielding at the same time. The shield can also opened to reveal 18 fire linked beam guns, called a "Beam Harmonica". For unexplained reasons, in all of Kid's capabilities as an MS engineer, he never reverse engineer the Flash System nor tried to recreate the Satellite Cannon when he had access to MS manufacturing facilities; its presumed he never had the means to recreate the weapons system.
The control console of the Gundam X Divider remained unchanged in the unit, requiring it to be piloted with a G-Controller. This however was changed later as Garrod Ran went to pilot the GX-9901-DX Gundam Double X. The control console was changed to a standard console and became the personal mobile suit of Jamil Neate. Under the control of a New-Type, X Divider can still access its remote bits, FX-9900 GX-Bit, through the Flash System for combat support, but due to Jamil's own mental damage in combat, it's a unreliable ability and only exploited once. Overall, while not as powerful as it was with its Satellite Cannon, Gundam X Divider is still a formidable unit in battle. [Source: wikia]
