Technology & Combat Characteristics
Developed based on the working space suits on board the exploration ship Tsiolkovsky, the Proto GINN is the first mobile suit to be created. Developed for defending the PLANTs and for invading earth, its humanoid design gives it high versatility, The Proto GINN has no built-in weaponry and is designed to use handheld weapons. The suit cannot be used by a Natural as it is only installed with Coordinator-use OS.
The first mobile suit built by ZAFT and the first suit ever built was the YMF-01B Proto GINN. It served as the prototype for the later mass-produced ZGMF-1017 GINN. Afterwards many Proto GINNs were redesignated as ZGMT-01 GINN Trainers, and all ZAFT mobile suit pilots initially trained on this machine. Even in CE 73, the suit was still used to train new pilots despite the presence of the newer ZAFT Armed Keeper of Unity series of MS.
- The Proto-GINN bears a close resemblance to the Universal Century's MS-05 Zaku I. Like wise the Proto-GINN's successor unit, the ZGMF-1017 GINN, closely resembles the MS-06 Zaku II. The GINN and Zaku mobile suit lines performed similar roles in their respective timelines, as the events of the Cosmic Era were largely derived from those of the early Universal Century.
