Gundam X Divider was developed from the GX-9900 Gundam X by Kid Salsamille after it suffered a devastating defeat against the RMSN-008 Bertigo. The majority of the Gundam X's equipment was heavily damaged, and it was not feasible for Kid to restore the mobile suit to its original configuration. So he opted to do 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 named it as GX-9900-DV Gundam X Divider, after its new shield.
As the Satellite Cannon was damaged beyond repair and there were no spare components, it was replaced with a new backpack. This backpack stores two large beam swords and has two energy tanks for extended flight time, as well as a storage attachment for the suit's new main weapon - the Divider. The Divider was a multifunctional shield created by Kid through the cobbling of items in his stockpile of spare parts. When mounted on the Gundam's back, the Divider's thrusters can be used for flight. It can also be handheld horizontally for the same purpose, while being used for defense.
