Following the successful testing of Newtype pilots Elpeo Ple and Ple Two using their Qubeley Mark-II units, Glemy Toto - claiming to be a genetically-engineered descendant of the late Principality of Zeon leader Gihren Zabi and intent on staging a coup against Haman Karn for control of Neo Zeon - began mass production of an improved Qubeley to be manned by his army of Ple clones. This resulted in the AMX-004G Qubeley Mass Production Type.
The Qubeley Mass Production Type was introduced in the last days of the First Neo Zeon War. With a Newtype army at his command, Glemy would start his civil war against Haman; however, very determined Haman loyalists - aided by a lot of luck and a bit of their own Newtype abilities - stopped the Ple clones and their mass-produced Qubeleys, resulting in an almost complete mutual annihilation of both Neo Zeon factions.
Early production models were painted gray, but the final production models were rolled out in a purple and pink paint scheme similar to the Qubeley Mark-II Unit 1 piloted by Elpeo Ple. Some records also indicate that the Qubeley Mass Production Type was also assigned the model number AMX-017, though this piece of trivia is debatable.
A heavily damaged unit was somehow acquired by the Vist Foundation and later used in U.C. 0096 to recondition Marida Cruz, who is one of the only surviving Ple clones.
