[1] In 2000, it has been discovered that dinosaurs have survived past their supposed extinction and reside in a vast underground environment where they have gained an intelligence on par with that of the human race.

They are led by a hyper-intelligent tyrannosaurus named Ururu (known as Emperor Tyrannus in the English dub) who plans to eradicate humanity and reinstate dinosaurs as the dominant life-forms on Earth by using his powers to brainwash his subjects into destructive monsters that obey his every command, sending them out on to the surface world to wreak havoc on human civilization.
