After the success of "Godzilla vs. King Ghidorah", producer Shōgo Tomiyama and "Godzilla" series creator Tomoyuki Tanaka proposed resurrecting King Ghidorah in a film entitled "Ghidorah's Counterattack", but relented when polls demonstrated that Mothra was more popular with women, who comprised the majority of Japan's population. Tomiyama replaced Ōmori with Takao Okawara as director, but maintained Ōmori as screenwriter. Hoping to maintain as much of "Mothra vs. Bagan" as possible, Ōmori reconceptualized Bagan as Badora, a dark twin to Mothra. The character was later renamed Battra (a portmanteau of "battle" and "Mothra"), as the first name was disharmonious in Japanese. Tomiyama had intended to feature "Mothra" star Frankie Sakai, but was unable to because of scheduling conflicts. The final battle between Godzilla, Mothra and Battra was originally meant to have a more elaborate conclusion; as in the final product, Godzilla would have been transported to sea, only to kill Battra and plunge into the ocean. However, the site of their fall would have been the submerged, Stonehenge-like ruins of the Cosmos civilization, which would have engulfed and trapped Godzilla with a forcefield activated by Mothra.
