This suit's aesthetic is that of dull metal, being gray and drab in appearance. It features segmented, angular pieces, with bolts lining its body. The joints of the suit feature segmented, darker shaded pieces that allow for flexibility and movement.
The ShodaiMekagoji also features short, but smooth dorsal plates, with a short tail. There're prominent red "MG" initials on its arms that stand for "Mecha Godzilla."
The head of this Mekagoji design is very angular, with a snub snout featuring dual nostrils. The brow of the design is very defined, and the eyes of the Mekagoji suit are a bright orange, with a small, forward facing spike adorning the forehead of the design.
- The head of this suit was repainted and reused for the GyakushuMekagoji suit in Terror of Mechagodzilla.
