MS-05 Zaku I/Origin

The MS-05 Zaku I was the Principality of Zeon first prototype mobile suit developed as part of its mobile suit project designed for Mass Production as well as actual combat against the Federation.

History
According to the Director General of Anehiem Electronics the MS-04 was completely over budget and as a result the MS-04 was redesigned for Mass production which lead to the creation of the MS-05 "Zaku". A Squadron comprised of 4 MS-05 Zaku's 3 piloted by the Mash, Ortega, Gaia and the final one being piloted by Char Aznable, alongside Ramba Ral in a MS-04 engaged in the the first Mobile Suit battle against 12 RX-77-01 Guncannon which were dispatched in effort to rescue Trenov Y. Minovsky who at the time was attempting to defect. Ultimately the 2 Squadrons of Guncannon were wiped-out and Dr. Minovsky was crushed to death by a falling Guncannon as it attempted to flee.
