Zilla, originally known as Godzilla, is a film monster originating from TriStar Pictures's Godzilla. It was initially created as a reimagining of Toho's Godzilla but was later re-branded as a separate character.
When an extraterrestrial Titan arrives on Earth and starts to wreak havoc, Godzilla has to rise up and defend the world against this threat, with the help of Zilla II and a newly hatched Mothra.
