165. GX-9900 Gundam X

GX-9900 Gundam X (aka Gundam X, X) is a mass-produced MS built by the former United Nations Earth in After War Gundam X. There are two feature versions of Gundam X. The primary featured one was piloted by Garrod Ran and later to Jamil Neate. It was later badly damaged in combat and was repaired and rebuilt as GX-9900-DV Gundam X Divider.
The second one was featured in the manga sequel, After War Gundam X: Under the Moonlight. The story featured a different Gundam X (adorned with teal colors) and its pilot was Rick Aller.

Built at the height of MS advancement by the UNE, the GX-9900 series is one of the most advanced MS of its time. The series was mass-produced and pressed into service near the end of the 7th Space War. After the environmental devastation at the end of the 7th Space War, MS development on Earth became stagnant as humanity recovered; Gundam X and its brethren Gundam series remains top-of-the-line after 15 years. Because the UNE no longer existed, there was no regulation over the Gundams and they found second-life in the hands of the Vultures. It's because of Vulture-use that no two Gundam X is exactly alike.
