A mobile suit utilizing the "GUND FORMAT" technology provided by Prospera Mercury. The Schwarzette is a next-generation concept model, developed as a successor to the MD-0064 Darilbalde. The intention was to create a mobile suit with greater flexibility, adaptability, and mobility than the Darilbalde, by further enhancing the AI control system. However, due to technical setbacks surrounding the AI control system, development was halted for a long period of time. The utilization of "GUND FORMAT" technology allowed development on the Schwarzette to resume, transforming it into a Gundam.
Prior to the creation of GUND-ARM, Inc., Vim Jeturk began development on a Gundam-type mobile suit in collaboration with Shin Sei Development Corporation, insisting that both companies go into the drone business together.
When Guel became the CEO of Jeturk Heavy Machinery, the incomplete Schwarzette was revealed to him and Miorine by Prospera, much to Miorine's dismay. Prospera suggested using the Schwarzette as a joint development between Jeturk and GUND-ARM, Inc. to win support from members of the Benerit Group, to which Miorine declined.
Its upgraded Gundam form was later transferred to Asticassia's Jeturk House, where its presence was questioned by Lauda who was told that the Schwarzette was a joint venture between their company and GUND-ARM, Inc.
Lauda later piloted the Schwarzette in an attempt to kill Miorine, who he blamed for his family's recent misfortunes. The Shell Unit was destroyed during combat against Guel's Dilanza.
The Schwarzette, alongside the FP/A-77 Gundam Pharact, was later controlled by Suletta Mercury through the X-EX01 Gundam Calibarn to create a data storm powerful enough to remotely shut down the Space Assembly League's Interplanetary Laser Transmission System. The resulting data storm would ultimately disintegrate all nearby machines using the GUND FORMAT, including the Schwarzette.
