The MS-05Q Zaku I (Norris Custom) is a variant of the MS-05A Zaku I Early Type. It is piloted by Norris Packard from Mobile Suit Gundam: The 08th MS Team. It first appeared as a part of the MSV-R line.
As Zeon worked to upgrade its aging MS-06 Zaku II series during the One Year War, they intended to replace the space-use mobile suit MS-06F Zaku II with a new high-performance model the MS-11 Action Zaku. But it was still under development, a MS-06R-1A Zaku II High Mobility Type was heavily modified to serve as a testbed unit for the Action Zaku's development team
The MS-06G Zaku II High Mobility Ground Type (A.K.A Zaku Type G) is one of many variants of the standard MS-06 Zaku II created by the Principality of Zeon during the One Year War. It was first mentioned in Mobile Suit Variations, but never had official lineart until release of MSV-R.
