Technology & Combat Characteristics
The OZ-13MSX1 Vayeate and its sibling unit, the OZ-13MSX2 Mercurius, were a pair of space-use mobile suits developed for OZ by the five captured Gundam Scientists using the OZ-12SMS Taurus as a reference. Whereas the Mercurius was designed as a defensive mobile suit, the Vayeate was designed primarily as an offensive unit. Both suits were designed to operate together, with one covering the other when in battle. The Vayeate, built from the same basic frame as Mercurius, was armed only with a large beam cannon. However, this beam cannon's destructive power exceeds that of the XXXG-01W Wing Gundam's powerful buster rifle, and it also does not have the latter's three shots limit. This is because the beam cannon is powered by a beam generator mounted on the mobile suit's back, providing the weapon with a virtually limitless "ammunition" charge. The Vayeate and its brother, Mercurius, mounts a cover to protect their head sensor, but it also limits vision. A second unit controlled by a Mobile Doll AI System was later built by White Fang.
History
While the five Gundam pilots were fighting on Earth to defeat the OZ and the Alliance forces, the scientists who created their mobile suits were captured by OZ and forced to work on next generation mobile suits capable of putting an end to the Gundam pilots' activities. The five scientists set to work and came up with a pair of mobile suit designs – the OZ-13MSX1 Vayeate and the OZ-13MSX2 Mercurius. The Vayeate was later assigned to Gundam pilot Trowa Barton, who was acting as a double agent then. The Vayeate was then damaged beyond repair in a battle against the XXXG-00W0 Wing Gundam Zero, piloted by Gundam pilot Quatre Raberba Winner, who had became emotionally unstable.
The Vayeate's combat data and design were later utilized in the development of the OZ-02MD Virgo. Subsequently, another Vayeate was built by White Fang alongside another Mercurius as a pair of mobile dolls, both programmed with the recorded data of the originals' pilots. Shortly after their completion, the two mobile dolls were launched to intercept and destroy Hilde Schbeiker who had stolen important data from the battleship Libra. The machines would have succeeded in the mission if not for the intervention of Duo Maxwell piloting his XXXG-01D2 Gundam Deathscythe Hell who managed to destroy both mobile dolls.
