Gundam Sentinel

Introduction

It is UC 0088, in the last weeks of the struggle between the AEUG and the Titans, when a small group of elite Federal Forces officers stationed at the asteroid fortress Pezun revolt against the pro-AEUG Federation leadership. Declaring themselves the "New Desides" (a hybrid of "decision" and "dissident"), they swear to fight on for the Titans' ideology of Earthnoid supremacy. Although the Axis is the major threat on the horizon, the Federation decides that this rebellion must be nipped in the bud. Taskforce Alpha, a small force of Federal Forces, AEUG and Kalaba veterans, is dispatched to Pezun to teach the New Desides a lesson. In order to intimidate the rebels, Taskforce Alpha is equipped with the very latest advanced mobile suit hardware, including a handful of Gundams -- the most powerful of which is the Superior Gundam, piloted by young hotshot Ryuu Roots. The Superior Gundam is equipped with an artificial intelligence system called ALICE, which will intervene many times to save Ryuu's bacon and, over time, develop true self-awareness...

Pezun

Taskforce Alpha arrives at Pezun and, after a few skirmishes, begins a full-scale assault on the asteroid. The New Desides, however, abandon Pezun and leave a nuclear booby-trap for the invaders. Taskforce Alpha pilot Tex West realizes they've been tricked, and the attacking force withdraws just in time. Meanwhile, the New Desides flee to the friendly lunar metropolis of Ayers City. Unexpectedly, a new enemy surfaces. Federation Admiral Brian Eno, commanding a fleet that has been dispatched to support Taskforce Alpha, instead throws his lot in with the New Desides. Now Taskforce Alpha faces not only the New Desides, but its own main force, thanks to Eno's betrayal.

Ayers City

The New Desides are now holed up in Ayers City, making it politically unfeasible for the Federal Forces to stage a full-scale attack. Taskforce Alpha attempts to land mobile suits on the moon and root out the rebels, but the descending pilots are caught in a two-pronged counterattack. New Desides spies have cracked the software of Taskforce Alpha's mobile suits and fashioned a "logistic bomb" that renders their computer systems useless, while New Desides leader Brave Cod has received a fearsome new mobile suit from the traitorous Eno. Cod's Gundam Mark V ravages the helpless Taskforce Alpha mobile suits and forces them to retreat. The Federation sends reinforcements to join Taskforce Alpha in lunar orbit, and the combined "Eagle Force" stages an all-out assault on Ayers City. The New Desides had relied on the other lunar cities to oppose the Federation's act of agression, but the political support they expected never materializes. The ferocious battle continues for eleven days, until Brave Cod is killed in combat with Ryuu Roots' Superior Gundam and Ayers City mayor Kaiser Pinefield decides to throw in the towel. All seems lost for the New Desides, until an Axis fleet arrives on the scene. Honoring their pact with the Titans, the Axis forces cover the escape of the remaining 28 rebels.

Penta

The new leader of the New Desides, master strategist Tosh Cray, devises a desperate plan. The handful of survivors will seize the relay station Penta, in low Earth orbit, and from there launch an attack on the Federation Senate at Dakar. Their Axis rescuers loan the New Desides a powerful weapon, the re-entry-capable mobile armor Zodiac, for this purpose. Meanwhile, Taskforce Alpha's flagship, the Pegasus III, has been assigned to pursue and observe the remaining rebels. Arriving at Penta, the Pegasus III and its remaining mobile suits confront Tosh Cray as he puts his plan into action. A running battle begins in the upper levels of Earth's atmosphere as Cray pounds Taskforce Alpha with the mighty Zodiac. Ryuu, Tex and their comrade Shin Crypt pile into the three-seater Superior Gundam and enter the fray. During this critical battle, ALICE manifests her full potential, swatting aside the New Desides' ace pilots with ease. But it's too late to stop Cray's plan, as one of the Zodiac's two sections and a New Desides shuttle have begun the re-entry process -- the Superior Gundam cannot follow them down without being destroyed. At this point, ALICE takes matters into her own hands. Ejecting the re-entry-proof core block containing her three passengers, she pursues the last of the New Desides down through the atmosphere, managing to wipe them out before the Superior Gundam itself burns up. Sacrificing herself for the sake of her human comrades, ALICE at last becomes fully human.
