Widely regarded as one of the best Godzilla suits of all time, the MosuGoji is as different from the KingGoji as the KingGoji was from its two predecessors, ShodaiGoji and GyakushuGoji. The body of the MosuGoji suit was sleek and bell-shaped with a pronounced breast bone and knees. The hands featured slender, sharp and menacing claws with the fingers held apart. The dorsal plates were nearly identical to those of the KingGoji suit. The facial features were defined, with pronounced brows and really menacing eyes.
In Ghidorah, the Three-Headed Monster, the MosuGoji suit was given different facial features. Movable eyes were inserted, the upper lip and teeth were reduced and the tongue elongated, going past the lower row of teeth. This suit is also called the SanDaikaijuGoji (三大怪獣ゴジ?).
The MosuGoji was remade as a Godzilla fan made a costume out of the same fragments that Toho used to make their Godzilla suits, giving it a striking resemblance to the original costume. To make an exact replica, the creator had to use several images of the monster.
