Tyratant: Leader of the Kaiju

Tyratant: Leader of the Kaiju is a sci-fi/fantasy film.

Plot
Tyratant, seemingly a mixture of a Tyrannosaurus and Rat, with the body of a Tyrannosaur, the feet and hands of a rat, and a sharp-toothed maw, emerges from the Marianas Trench. This nasty creature was created by the Earth to bring an end to human's pollution and harm to the ecosystem.

A U.S. Government member under the name of George Lanton, is on board of a Navy cruiser when the massive creature is caught on radar. After following it, the creature disappears.

Once the cruiser returns to the Washington state coast, Lanton reveals the information to the president, who asks the U.S. Navy and biologists to keep an eye on this creature, and if possible, study it.

They track the creature over into the Atlantic Ocean, and Tyratant shows himself to the world when emerging on the Florida coast, destroying Miami with radioactive beams from his hands and fire from his mouth.

The President decides it's best the creature gets taken down, but it disappears.

The Japanese Government finds the creature along the coastline, and it emerges near Tokyo, laying serious destruction to the major city. The Japanese Air Force, flying in Mitsubishi F-2 aircraft, attempt to attack the creature. The U.S. comes to the aid of Japan in state-of-the-art F-35 Lightning II aircraft, and both air forces pummel the creature.

At this point, all weapons are aimed at the creature and firing full blast. Tyratant sinks into the water and causes an explosion to make everyone assume he has been destroyed, and he slips back deep into the water, now undetectable.

Everyone thinks it is all over, but giant creatures start emerging all over the world.
