Dorat's name comes from the "dora" in "King Ghidorah," and the "tto" in its Japanese name may mean "to head", referencing how the three Dorats become King Ghidorah's three heads.
The Dorats were genetically engineered to be the perfect pets in the 23rd century.
The Dorats were three genetically engineered pets brought from the future by the Futurians. They were kept on the Futurians' ship and they were taken back in time to before the hydrogen bomb that mutated the Godzillasaurus hit the islands near Lagos Island. They were released into the wild, while the Futurians went back to the present. The Dorats stayed on Lagos Island until 1954, where the hydrogen bomb mutated them into King Ghidorah.
Dorats can use their wings to fly and they also can sense feelings through microwave impulses.
