After the end of the Heisei Era of Godzilla movie series, the right to Godzilla was given to TriStar Pictures, who created their own version of a Godzilla movie, named Godzilla, in 1998. In this continuity, "Godzilla" is a mutated marine iguana, the result of nuclear testing in the Maruroa Atoll Islands of French Polynesia in 1968.
After Toho got the rights to Godzilla again for the Millennium movie series, the King of Monsters returned with his more traditional look. The lightly-built version of Godzilla created by TriStar was then given a new identity, named "Zilla". Zilla had a minor role in Godzilla: Final Wars, where it was among the monsters controlled by Xiliens to bring destruction to humanity. However, like all other Xiliens-controlled monsters (with the exception of Gigan and Monster X), Zilla was quickly defeated by Godzilla himself.
