Scorpio

The OZ-16MSX-D Scorpio is a large, heavily armored, transformable mobile suit developed by OZ specifically for fortress defense. The Scorpio has two distinct modes: Mobile Armor (MA) mode and Mobile Suit (MS) mode. In its MA mode, the Scorpio boasts high offensive power and is equipped with powerful propulsion units that provide significant thrust, making it formidable in long-range combat. However, the MS mode is designed for close-range combat, sacrificing some of its armor and weaponry during transformation. This transformation process appears to be irreversible during combat, meaning once it switches to MS mode, it cannot revert back to MA mode until after the battle.

Typically, the Scorpio operates as an unmanned Mobile Doll, relying on automated systems for combat. However, by using the code "56WI," its Mobile Doll system can be deactivated, allowing it to be controlled manually as a manned mobile suit.

The Scorpio's armament is extensive and includes Beam Bayonets that function as both beam rifles and beam sabers, an A.S Planet Defensor for defensive measures, and Micro-missiles stored in the chest and shoulders for added firepower. Additionally, the Heat Rod, which is only available in MA mode, provides another layer of offense. Due to its massive size—1.5 times larger than a typical mobile suit—the Scorpio is not mass-produced, making it a unique and powerful asset in OZ's arsenal.
