Libra was a giant space battleship commissioned and built by OZ and designed by the five scientists who created the Gundams. In form Libra resembles five geometric diamonds, four of which are connected to a corner of the fifth in the center. Its name is derived from the Zodiac constellation Libra.
Although it was originally built by OZ, for the majority of its history Libra was operated by White Fang who had captured it thanks to their new mobile doll army
As a battleship Libra was well suited for its role possessing numerous defensive guns and capable of carrying hundreds of mobile suits. However its most powerful weapon is a massive beam cannon located in the central diamond. The devastating power of this cannon was unparalleled, however it was fired very rarely as the scientists who designed it made sure the weapon would be flawed and would break down after each time it was fired and required days to repair.
One of Libra's more unique features was a control room Zechs Merquise had built that incorporated Gundam Epyon's combat computer/pilot interface system. The purpose of this room was to allow an individual to command White Fang's mobile dolls in combat aided by the combat computer. This room was used exclusively by Dorothy Catalonia.
Eventually the leadership of White Fang decided to use the battleship to recreate the original Operation Meteor by dropping it onto Earth. The global devastation caused by such an action would ensure the death of all humans on Earth. As Libra made its war towards Earth it was encountered by the Gundams and an Earth fleet composed of Space Leos lead by Treize Khushrenada in the OZ-00MS2 Tallgeese II. Libra was eventually stopped when the Gundams' carrier Peacemillion collided with the battleship, however one of Libra's sections separated and continued forward. This section was forced to self-destruct when Zechs slashed through a power generator with Epyon's beam saber. This however was not enough as a smaller portion survived intact and while not large enough to wipe out all of humanity could still cause a massive amount of destruction. This final piece was intercepted in the atmoshpere by Heero Yuy where he used the Wing Zero's twin buster rifle to break the piece's structural integrity forcing it to break apart from the friction from the atmospheric reentry. The debris scattered and burned up harmlessly in the atmosphere visible as a meteor shower from the Earth's surface.
