The SokogekiMosuImago's name comes from the film's Japanese title, specifically sōkōgeki (総攻撃?), meaning all-out attack, Mosu, from Mothra's Japanese name, Mosura (モスラ?), and Imago, from the fact that it is a design for Mothra's Imago form.
The SokogekiMosuImago is very diffrent from the previous and later designs. It looks more like like a hornet and Moth hybrid. The eyes are purple instead of the usual blue, the legs are much longer and the wings are pointier. On the wings, it has a similar pattern to Mothra Leo from the Rebirth of Mothra trilogy but with purple on the top, yellow in the middle and red on the bottom instead of orange on the top and green on both the middle and bottom or all seven colors of the rainbow like Rainbow Mothra.
