OZ-13MSX1B-S Vayeate Suivant

The Vayeate Shuvian is the upgraded version of the Vayeate developed by OZ and operated by the OZ Prize. It appeared in Gundam Wing Dual Story: G-UNIT.

Combat Characteristics
Whereas the Mercurius Shuvian was designed as a defensive mobile suit, the Vayeate Shuvian was designed primarily as an offensive unit. The Vayeate Shuvian, built on the same basic frame as its Mercurius twin, was armed with two large beam cannons. These cannons were designed to provide a damaging blow almost equivalent to that of the XXXG-01W Wing Gundam's powerful buster rifle. To overcome the problem of the buster rifle's limited charge, the scientists designed a large energy collector, providing the Vayeate's beam cannon with a virtually limitless "ammunition" charge. Both the Mercurius Shuvian and Vayeate Shuivan were used as testbeds for the OZ-00MS2B Tallgeese III.

Trivia
Vayeate Shuivan's motif is derived from the Fujin, a mythical demon in Japanese Mythology.
