MSZ-006-X Prototype Ζ Gundam

The Prototype Z Gundam series are three mobile suits which appear as part of the Mobile Suit Variation of the series Mobile Suit Zeta Gundam.

History
Before the MSZ-006 Zeta Gundam was created, three faulty prototypes were built. Technically, all three units were the same machine, but each unit had a different head design. The MSZ-006-X1 has a head similar to the MSN-00100 Hyaku Shiki, MSZ-006-X2 featured a head borrowing it's look from the RMS-099 Rick Dias's head and MSZ-006-X3 used a head similar in comparison to the MSA-003 Nemo's head.
