OZ-16MSX-D Scorpio

History
The OZ-16MSX-D Scorpio is a single large mobile suit appearing solely in the Battlefield of Pacifists manga. The mobile suit design was created by Junya Ishigaki,while the mobile armor was created by Koichi Tokita. Although not stated outright, the name is derived from the Zodiac constellation of Scorpius.

In the manga, the Scorpio is a one-of-a-kind mobile suit developed to guard the Mobile Doll factory of Vulkanus. It is the largest mobile suit in the After Colony Era. During AC 196 (between Gundam Wing and Endless Waltz), several groups began searching for Vulkanus, which had drifted out of its stable orbit. The Scorpio attacked those who found the site, until Perfect Peace People leader Victor Gaintz used the suit's codes to disable the Mobile Doll system and become its pilot. Gaintz was killed by Heero Yuy and Wing Zero.

The main weapon of the Scorpio is the beam bayonet, which combined the beam saber and beam rifle into a single unit. The A.S Planet Defensor is an enlarged countepart of the devices mounted on the Virgo mobile dolls, and functions as a beam shield. The transformation between modes is believed to be one-way, as the armor skirt, propellant tanks, and additional weapons were shed, and could not be reacquired in combat. The mobile suit was destroyed before a reverse transformation was depicted in the manga.
