, is a fictional monster, or kaiju, in Toho Co., Ltd.'s Godzilla media franchise. The character first appeared in Godzilla (1998), released by TriStar Pictures. It was initially created as a reimagining of Godzilla but was later re-branded as a separate character. Patrick Tatopoulos designed it after iguanas with a slim theropod appearance rather than the thick, bipedal designs of Toho's Godzilla. TriStar's Godzilla, both the film and character, were negatively received by fans and critics. In 2004, it was featured in Toho's Godzilla: Final Wars as "Zilla". Afterwards, Toho trademarked new incarnations as Zilla, with only the iterations from the 1998 film and animated series retaining the Godzilla copyright and trademark. Overview Name Initially, during production of Godzilla: Final Wars, director Ryuhei Kitamura asked producer Shōgo Tomiyama whether or not they were allowed to include TriStar's Godzilla in the film; whereupon Tomiyama checked Toho's contract with Sony and saw they were allowed to use it, Tomiyama stated: "Kitamura asked me if it was possible for us to use the American Godzilla in Final Wars, so I checked our contract with Sony Pictures and found out we could use it. Since this was the 50th anniversary film, I thought ‘Why not include the American Godzilla?'" This incarnation of TriStar's Godzilla was named "Zilla". This decision was made because they also felt that Emmerich's film had taken the "God" out of "Godzilla" by portraying the character as a mere animal. The name "Zilla" was chosen for the character by Tomiyama as a satirical take on counterfeit Godzilla products that use "Zilla" as a suffix. Toho had filed the "Zilla" name on July 21, 2006, and it was registered on April 20, 2007. This name change has been reflected in subsequent official products featuring the character since 2004, though "Godzilla" continues to be used on products that predate the name change, such as home media re-releases of the 1998 film and Godzilla: The Series. Matt Frank (co-writer and illustrator of Godzilla: Rulers of Earth) further clarified the name change, stating, "Toho makes zero distinction between "Zilla" and "Godzilla 1998" with the exception of title alone. Ever since 2004, Toho's official stance has been that any future incarnations of the character be referred to hereafter as 'Zilla'." Keith Aiken (co-editor of SciFi Japan) also clarified that "Zilla is a variation of the 1998 Godzilla" but stressed that only the incarnations from the 1998
