The EMS-04 Zudah competed against the MS-05B Zaku I in the race to become the primary Mass Production Mobile Suit for the Principality of Zeon. The Zudah vastly outperformed the Zaku I in maneuverability tests but was compromised by its experimental Jupiter Engine. This engine tended to explode and cause the Mobile Suit to break into pieces, which, coupled with its high production cost, made the Zaku I an easy choice over the experimental EMS-04 Zudah. After the war had started, Zeon resurrected the Zudah with a new EMS-10 designation. The new EMS-10 Zudah features a much more stable Saturn Engine as well as several unknown improvements.

This HGUC rendition of the EMS-10 Zudah includes:

• 120mm Zaku Machine Gun
• 135mm Anti-Ship Rifle
• Heat Hawk
• Sturm Faust
