In Ghidorah, the Three-Headed Monster, the SanDaikaijuGoji's name comes from the film's Japanese title, specifically san daikaiju (三大怪獣?), meaning three giant monsters, and Goji, which comes from Godzilla's Japanese name, Gojira (ゴジラ?).
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 large angry-looking eyes. The suit's eyes could move, a first for the series, although a scene in the film shows Godzilla with no pupils because the eyes rolled upwards.
In Ghidorah, the Three-Headed Monster, the MosuGoji suit was given a new head with 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 was done due to damage the suit's head had sustained during the previous film, primarily the scenes where Godzilla smashes headfirst into a pagoda and later when his head briefly sets on fire. This suit is also called the SanDaikaijuGoji (三大怪獣ゴジ?).
- MosuGoji was the first Godzilla suit to be used as the primary suit in more than one movie.
- The suit was also used by Eiji Tsuburaya and Tsuburaya Productions to create the monsters Gomess, from Ultra Q, and Jirass, from Ultraman, but Jirass had DaisensoGoji's head and MosuGoji's body because the head of MosuGoji was already used for Gomess.
- 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.
- Mosugojira was the name of an insect monster from Mirrorman.
- One of the two Godzilla suits used in the 1983 fan film Godzilla vs. Wolfman is a replica of the MosuGoji, the other being a replica of the KingGoji.
