The Illusion is a limited production mobile suit developed by the Illuminati's Saviour team, led by John Saviour. Designed with a focus on high mobility and maneuverability in zero-gravity conditions, it shares similarities with the G-SAVIOUR G-Saviour Space Mode. The Illusion is particularly notable for its lightweight armor and the extensive array of thrusters positioned across its body, enabling exceptional agility in space.
A distinctive feature of the Illusion is its avian-like claws on its feet, which provide enhanced stability and footing on various terrains, a design choice that sets it apart from other mobile suits. Additionally, the Illusion's EP09-SC Type cockpit is equipped with a life support system capable of sustaining the pilot for up to 96 hours, surpassing the 72-hour capability of the G-Saviour's EFX-8 Type cockpit. This extended life support duration makes the Illusion well-suited for prolonged missions in the harsh environment of space.
