The TokyoMosuLarva's name comes from Godzilla: Tokyo S.O.S.'s Japanese title, specifically Tōkyō (東京?), Mosu, from Mothra's Japanese name, Mosura (モスラ?), and Larva, from the fact that it is a design for Mothra's Larva form.
TokyoMosuLarva is similar to the HeiseiMosuLarva design, only darker in color. The other differences is that the lamps for eyes can glow either red or blue. Like the HeiseiMosuLarva and SokogekiMosuLarva puppets, it is remote controlled instead of being controlled by wires.
