After Colony Gundam

"When wars are dehumanized, both victory and defeat become miserable, and God no longer lends a helping hand."

After Colony Gundam is the second Gundam AU, returning to a similar core pitch to that of Universal Century Gundam, with oppressed spacenoids and a heavy emphasis on a semi-conventional military-industrial complex.

New Mobile Report Gundam Wing

Seeking independence from an uncaring Earth government, the colonies -- each located at one of Earth's Lagrange Points -- deploy five mobile weapons called Gundams to fight against the Romefeller Foundation and its Organization of the Zodiac, a secret society wound around the Earth's military and government.

New Mobile Report Gundam Wing: Endless Waltz

Less than a year after the dramatic multi-way battle at the end of the television series, a new foe -- the Mariemaia Army, led by Dekim Barton alongside a child who appears to be the daughter of Treize Khushrenada -- threatens to execute the original plan for Operation Meteor and take over the Earth Sphere.

Integration Notes

The following are things that were adjusted, changed, or shifted as part of the integration of After Colony Gundam content on SRTMOO.

OZ has been primarily, though not exclusively, rolled into the G-Hound unit of the Earth Federation. Most Organization of the Zodiac PCs will start here.
There is a behind-the-scenes connection between Operation Meteor and Celestial Being; Operation Meteor in its current state is not strictly a Celestial Being operation as far as most Celestial Being battlegroups are aware, but they have been directed by Veda to support Operation Meteor participants as the opportunity arises.
The Sanc Kingdom operation that takes place in the first 10 episodes of Gundam Wing has already occurred, leaving the Sanc Kingdom's status shaky.
In a nod to a sight gag barely visible at standard definition, Gundanium is indeed Gundarium Theta, connecting it to the Universal Century Gundam series.
The Organization of the Zodiac/Romefeller Foundation is connected to multiple other conspiracies, including Cosmic Era Gundam's LOGOS, Banpresto Originals' The School, and Code Geass's Schneizel Faction. By extension, this makes Blue Cosmos an easy source of useful idiots.
As a nod to each Gundam and its pilot being from a Lagrange Point-attached colony, each Gundam pilot is... well, actually from somewhere in that Lagrange Point. This varies how relevant it is to each character.
