The Michaelis is a new model MS developed by Grassley Defense Systems that is equipped with the same "Antidote" Anti-GUND Format equipment seen on its predecessor, the CEK-040 Beguir-Beu. The Beam Bracer, a combination armament, replaces the manipulator on its right arm.

The CFP-010 Heindree (ハインドリー Haindorī?) is a mobile suit introduced in Mobile Suit Gundam the Witch from Mercury. The latest in the all-purpose Grassley Defense Systems' Hein series, based on their standard Hein OS. Designed for coordinated combat just like the rest of the series, this unit's additional capabilities allow for a broader range of applications. It is the successor to the Heingra, a specialized battle unit which dominated against Gundams during the Vanadis Incident, but its more modest armor and internal components make it more suitable for use in the educational and private sectors.

CEK-077 Beguir-Pente (ベギルペンデ Begirupende?) is a mobile suit introduced in Mobile Suit Gundam the Witch from Mercury. It is piloted by the members of Grassley House. A successor to the CEK-040 Beguir-Beu developed by Grassley Defense Systems. A high-performance mobile suit that incorporates Non-Kinetic Effectors, the core elements of the Anti-GUND Format equipment. Like its predecessor, the Beguir-Pente can release "Antidote" attacks that interfere with GUND FORMAT links. However, these "Antidote" attacks only affect GUND FORMAT links with Permet scores of 3 or lower.

The MSJ-121 Demi Trainer (デミトレーナー Demitorēnā?) is a mobile suit introduced in Mobile Suit Gundam the Witch from Mercury. Demi Trainers were developed for students of the Asticassia School of Technology, a school created for training personnel in the space development industry. The unit's design is stripped of all superfluous components, affording it superb maneuverability and serviceability. The MS can be modified by anyone with basic technical knowledge, giving it excellent potential for customization. In addition to these facets, Demi Trainers are said to be the best choice for those learning to pilot, making them an obvious choice for students at the school. If asked which MS they felt most comfortable with, students are most likely to answer, "Demi Trainer".

CEK-040 Beguir-Beu (ベギルベウ Begirubeu?) is a mobile suit introduced in Mobile Suit Gundam the Witch from Mercury PROLOGUE. It is piloted by Kenanji Avery. This is an MS developed by Grassley Defense Systems, one of the world's leading heavy industry manufacturers.

Guel's Dilanza (ディランザ グエル専用機 Diranza Gueru Sen'yō-ki?) is a mobile suit introduced in Mobile Suit Gundam the Witch from Mercury. It is piloted by Guel Jeturk. Among the basic MS Dilanza units developed by Jeturk Heavy Machinery, a number have been customized for their pilots.

Although it's a machine that can be handled by ordinary pilots, it displays a performance that sets it apart from the norm when Suletta is boarding it. Its powers are mediated by a new mineral called Permet, being very similar to the characteristics of the forbidden machine GUND-ARM, popularly known as "GUNDAM", which employed "GUND FORMAT", a system for MS that aimed at human augmentation.

The XGF-02 Gundam Lfrith (XGF-02 ガンダム・ルブリス Gandamu Ruburisu?), aka LF-03, is a mobile suit introduced in Mobile Suit Gundam the Witch from Mercury PROLOGUE. It was piloted by Elnora Samaya during the Vanadis Incident. This was a prototype MS developed by the Ochs Earth Corporation, a company that was established on Earth. The most prominent feature of this unit was the implementation of the GUND Format, where "GUND"—an innovative body function expansion technology based on artificial limb welfare engineering—was refined for mobile suits. The mobile suits that incorporated the GUND Format and gained cross-disciplinary fighting abilities were collectively called GUND-ARMs, and people across the world soon came to call them "GUNDAMs".
