This is a very plain looking Gundam I’ve seen so far.
GN-000 0 Gundam (pronounced Oh-Gundam), is the first mobile suit to be equipped with a GN Drive in seasons 1-2 of Mobile Suit Gundam 00.
It is the original prototype MS that lead to the development of all current Gundams in Celestial Being.
The unit was piloted by Ribbons Almark and later by Lasse Aeon.
Requires only 13 sheets of paper and comes with instruction for every part of the body.
