Gojira or "GDZ-01" is an Acrocanthozilla. It was one of the last creatures in the Sapience war, and was the last hybrid created in the Genetic arms race.
Acrocanthozilla was created as a response not to an creature part of the Genetic Arms race created during the Sapience War, but as a response to the Chaosinium powered machines used by the Sapient Dinosaurs and Sapient Animals aliance. It was only a few tonnes heavier than an Argentinosaurus, but was twice as Tall and Large.
Acrocanthozilla technically isn't part of the Genetic arms race, but there were a few species from the Genetic arms race that survived into the End of the Sapience war and "fought" Gojira. Only one unit was produced, but it caused mayhem wherever it went. Nothing could stop the mighty Gojira that mankind had unleashed. Its acid being able to melt Chaosinium crystals, its power and ferocity unmatched by the Strongest Tyrants, Hadrosaurs, and Titanosaurs, and it's size only matched by the skyscrapers of the 21st century.
While the Sophonts would eventually find a way to destory Gojira, the Acrocanthozilla wasn't created as a full on counter. But to buy time for the Chaos Cannon's construction.
