Godzilla wakes up from the seafloor and heads toward Antarctica.
Meanwhile, Cretaceous Ghidorah senses Godzilla and follows him to Antarctica.
When Cretaceous Ghidorah Arrives, he shoots fireballs at Godzilla. Godzilla ignores the fireballs and shoots his atomic fire at Cretaceous Ghidorah, knocking him out of the sky and crashing into an ice wall.
When Cretaceous Ghidorah gets up, he bites into Godzilla's neck. Godzilla then bites into one of Cretaceous Ghidorah's necks, making him let go of Godzilla's neck, and throwing him into an ice wall. Then Godzilla shoots his atomic fire at Cretaceous Ghidorah constantly.
From the sky above, a stealth bombe drops an atomic bomb on both Godzilla and Cretaceous Ghidorah. The explosion collapses the ground the kaiju are standing on, making both fall and get buried in ice. Then, the stealth bomber rops another atomic bomb on them.
When the smoke clears, Godzilla breaks out from under the ice. As he is walking back to the sea, from the ice, Cretaceous Ghidorah emerges. However, he is very different.
Cretaceous Ghidorah is bigger in length, wingspan, and width. He is also larger than ghidorah, Monster X, and Desghidorah. Cretaceous Ghidorah is also much more scary looking than the original Ghidorah. Cretaceous Ghidorah also now looks more like Ghidorah than a dinosaur.
Now Cretaceous Ghidorah is Grand Ghidorah. Grand Ghidorah attacks Godzilla. Godzilla shoots his atomic fire at Grand Ghidorah. Grand Ghidorah is unfazed by Godzilla's atomic fire and shoots gravity beams at Godzilla.
Godzilla falls to the ground. Grand Ghidorah then bites into Godzilla's neck and throws Godzilla into and ice wall. Before Grand Ghidorah finish off Godzilla. Godzilla shoots Grand Ghidorah's middle head with his atomic breath and knocks Grand Ghidorah down.
When Grand Ghidorah gets up, he starts to fly away. But then Godzilla uses his atomic breath and knocks Grand Ghidorah into the ocean. Godzilla goes after Grand Ghidorah.
Under water, Godzilla bites down into Grand Ghidorah's middle neck. Grand Ghidorah then bites down on Godzilla's neck. Godzilla gets free and uses his atomic fire and shoot Grand Ghidorah into and ice wall. Then, Godzilla used his atomic breath to shoot the ice around Grand Ghidorah, Burying him.
Godzilla surfaces and heads toward Alaska.
When Godzilla arrives, Desghidorah attacks him. Godzilla uses his atomic breath and shoots Desghidorah into some buildings. Then Godsilla grabs Desghidorah's tail and throws him into the ground.
Desghidorah gets up and shoots energy bolts at Godzilla and knocks him down. When Godzilla gets up, Desghidorah bites into Godzilla's neck. Godzilla gets free and hits Desghidorah into the ground with his tail.
Godzilla then continuously shoots Desghidorah with his atomic fire. Then, Godzilla's atomic fire goes through Desghidorah's chest and kills him.
Godzilla then heads toward San Francisco.
When Godzilla surfaced in San Francisco, Monster X destroyed the entire city. When Monster X saw Godzilla, it shot its antigravity beams at him, knocking him down.
When Godzilla gets up, he shoot Monster X with his atomic fire and knocks him down. Then, Godzilla grabs Monster X's tails and throws him into the sky where Godzilla then shoots Monster X with his atomic fire as it is falling.
When Monster X falls to the ground, He gets on all fours and then he changes.
His arms and legs change to where it has 4 legs. Then all his white parts turn to a dark shade of gold. Then, his head like shoulders extend and then form heads. Monster X's shoulders and head extend up. From its back, wings appear. When Monster X's head and shoulders extend up high enough, they stop and its head and shoulders turn into heads similar to Ghidorah.
Monster X reveals itself to be Keizer Ghidorah and roars into the sky. Then, Keizer Ghidorah shoots its antigravity beams at Godzilla, knocking him down. Then, Keizer Ghidorah picks up Godzilla and flies up high. Then, Keizer Ghidorah drops Godzilla into buildings.
When Keizer Ghidorah lands, he grabs Godzilla's shoulders and neck and then starts to drain the radiation from Godzilla's body. But before Keizer Ghidorah can finish, Godzilla shoots Keizer Ghidorah and makes him let go. Then Godzilla rams Keizer Ghidorah into the ground and shoots the middle head clean off with his atomic fire.
Keizer Ghidorah gets up and regenerates his middle head. Then Keizer Ghidorah shoots his antigravity beams at Godzilla. Godzilla manages to dodge the antigravity beams and hits Keizer Ghidorah into the ground with his tail.
When Keizer Ghidorah got up, he bir into Godzilla's neck and yanked him to the ground. Godzilla used his atomic fire and shot Keizer Ghidorah's right wing, burning it a little. Godzilla got up and then shot his atomic fire at Keizer Ghidorah.
Keizer Ghidorah managed to get up and ram into Godzilla. Then, Keizer Ghidorah picks up Godzilla and flies into the sky. But before Keizer Ghidorah can drop Godzilla, Godzilla shoots his atomic fire at Keizer Ghidorah's wing, making him fall out of the sky.
Godzilla bites down on Keizer Ghidorah's middle neck while they both fall. When both kaiju make impact, it creates a massive shockwave.
When the dust clears, Godzilla emerges on top of Keizer Ghidorah. Godzilla shoots his atomic fire at Keizer Ghidorah's middle head, blowing it off, and then bites down on Keixer Ghidorah's front left leg. Then Godzilla rips of the leg and throws it into some debris.
Godzilla gets of Keizer Ghidorah. When Keizer Ghidoreah gets up, Godzilla shoots his left head with atomic fire. Godzilla then rams into Keizer Ghidorah and bites into his right head and rips it off. Then, Godzilla shoots at Keizer Ghidorah's chest for a long time. After Godzilla stops, Keizer Ghidorah's chest was only chard.
Keizer Ghidorah got up and regenerated his heads and leg. Then Keizer Ghidorah shot his antigravity beams at Godzilla. While Godzilla is distracted, Keizer Ghidorah flies into the clouds and out of sight.
