Characteristics
Zeta Gundam is one of the few Gundams with a white coloured chin. It is also different in shape, with a sharp shaped chin. The unit also featured wings and heat shield for atmospheric reentry. The detailed transformation design served as the first TMS in real life (although renewed and retconed by the Z Plus design later on), and the concept served as the basics of various mobile suit designs later in other Gundam series, including a simplified transformation of XXXG-01W Wing Gundam according to the model instruction manual of Wing Gundam.
