In 1945, man's arrogance made the americans throw the atomic bomb, which in 1954, collided with the island known as Odo Island. In the island, a Prehistoric Amphibious Reptile lives, and the bomb made him bigger and radioactive. The creature attacked Tokyo, Japan, and after the tragic event, he appeared again in 1955, attacking New York, and causing more destruction than his attack in Tokyo. Americans and Japanese people help themselves, and they made another atomic bomb, 10 times more powerful than the previous one. The radioactive beast was alone in his island, and they threw the bomb wich collided in Godzilla, and they killed the monster. But, the creature adopted a son...
Decades later, a creature similar to the first Godzilla that appeared in 1954, appears in Tokyo Bay, in 1999, and then, it was never seened again.
Now in the 21th century, a lot of creatures called kaijus appeared; Zilla appears in the Antarctica, Titanosaurus appears in Murud-Janjira, Gorosaurus appears in the the Katahdin mount, Mogu appears in the Florid desert, Hitodah in the Pacific ocean, Dragon in a place close to Murud-Janjira, Anguirus in the Atacama desert, Deutalios in the North pole, Yonggary in Alaska, Liopleurodon in the Indic ocean, Uchuujin in the Janjira city, Redmoon in the Pantanal of Brasil, and Bakan awakes. Wht they didn't know, is that they awakened the most powerful kaiju, Godzilla.
Godzilla decided to fix the problem of the kaijus around the world, and so, he goes to the surface, producing a lot of tunderbolts.
The Liopleurodon in the Indic Ocean, is attacked by Hitodah. The great mutation tries to devour the prehistoric reptile, but it devours the mutation. Liopleurodon is on its way to the north pole, but is attacked by a creature called Dragon.
Godzilla appears in Tokyo, and after having walked around the city, he is ambushed by a creature, Goliath. Godzilla defeats him with the Atomic Breath. Goliath backs away and leaves the city. Godzilla heads towards Antarctica, where Zilla was. Zilla had killed many animals, and many whales, but Godzilla appears, and hits the gigantic iguana, which collides with a mountain. Godzilla uses his Atomic Breath, which Zilla dodges, but is hit by the tail of Godzilla, who sends him flying through the air. Zilla throws a quantity of dust, and leaves that place. Godzilla loses sight of Zilla, so he goes to her next target, Murud-Janjira.
In the Atacama desert, Anguirus becomes depressed, because he misses his old friend, and he expects her to be fine. However, he smells a smell of rotten fish, just as he spots a shadow in the background, Deutalios appeared. The two began to fight, giving each other blows, kicks, scratches and in the end Anguirus transformed into his shape of spikes, and rolled, crashing into Deutalios. Deutalios makes a fugue, so Anguirus continues with his sad moment.
Redmoon flies to Mount Katahdin, where he meets Gorosaurus, and the two begin to fight. Redmoon uses its ability to throw rays through the nose, and seriously injures Gorosaurus. Redmoon keeps walking, killing anything she will find.
Meanwhile, in the Indian Ocean, Liopleurodon loses the battle, and sinks, while Dragon also goes towards Murud-Janjira. Godzilla approaches there, but suddenly, he has a hallucination, where a transparent Godzilla with scars appears. This halucination occurs thanks to Alzheimer's disease. Unlike what happens with humans, Alzheimer's produces strange hallucinations. After that halucination, Godzilla continues towards Murud-Janjira.
