During the Principality of Zeon's race to develop a superior fighting machine, they developed four prototype mobile suits from different engineering companies: one of these was Zimmad Company's EMS-04 Zudah. It had a good energy reactor, an well-rounded armament (120mm machine gun, 280mm bazooka, sturmfausts and a heat hawk Type3), and good rocket thrust. However, the suit did have limits: if the engines were overexerted, the suit would overload and break apart. Zeonic Company used this information to outdo the Zudah with their well-known MS-04 Prototype Zaku and successfully marketed the Zaku series.
