In Godzilla: Tokyo S.O.S., the TokyoMosuLarva's name comes from the film's Japanese title, specifically Tōkyō (東京?), 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.
In Godzilla: Final Wars, the FinalMosuImago's name comes from the film's title, specifically the word final (ファイナル?), Mosu, from FainaruMothra's Japanese name, Mosura (モスラ?), and Imago, from the fact that it is a design for Mothra's Imago form.
While the puppet kept the slim design of the previous SokogekiMosuImago puppet, it also featured a number of departures from its predecessor, returning to its fluffy and soft look and losing the wasp-like appearance. The trimmed-down approach gave it a more realistic appearance compared to the other fluffy HeiseiMosuImago and ShodaiMosuImago puppets. This puppet is also called the FinalMosuImago (ファイナルモス成虫?) in FainaruMosuSeichūGodzilla: Final Wars.
- The FinalMosuImago puppet was also used to characterize Mothra Imago in Toho's CR Godzilla game in 2006.
- This Mothra design, along with the MireGoji and the KiryuGoji Godzilla designs, are the only kaiju designs from the Millennium series that saw use in more than one film.
