MSZ-009 Prototype ZZ Gundam

The concept of the ΖΖ Gundam was tested in two MSZ-009 Prototype ΖΖ Gundam which can separated into two parts called G-Top Zero Type and G-Base Zero Type. (and could transform into G-Fortress Zero Type in SD Gundam Games). The Prototype ΖΖ Gundam's main purpose was to test combining mechanisms, which developed into a new core block system.
