Synopsis by Emru Townsend
Heero battles against impossible odds as he defends Luxembourg Base, the Treize Faction's headquarters, from the Romefeller Foundation's attack. When Duke Dermail learns that a Gundam has helped to wipe out half of their forces, he calls in ground forces to mount an assault on the base. Realizing that the Gundams and Treize are powerful rallying symbols, he wants to wipe them both out before they can join forces. At the Luxembourg Base, Heero makes his way into the base with the intention of killing Treize, but instead Treize convinces him to take his secret creation: a Gundam mobile suit he has named Epyon. In space, Romefeller's men are preparing to destroy the Gundam Zero; the sudden arrival of Zechs Merquise in the Tallgeese signals a change in plans -- or so it seems. With the bait taken, Romefeller launches an all-out attack on the Tallgeese, forcing Zechs to abandon it in favor of a newer, more powerful weapon: Gundam Zero.
