Continuing from the events of Antlar rising, Antlar rises up to destroy humanity as the Gammas have detected his energy signature as Antlar burrowing his way to Japan.

The Shobijin explain that Antlar shoots out a beam that attracts metal. With the city was being evacuated, the Air force use jets to takedown Antlar, but didn't harm him because of his exoskeleton as the creature uses his magnetic beam to disable the jets while the polits ejects as the beetle monster attacks Japan. Everyone, the Gammas, Zone Family, and Unicorn had prepare to takedown Antlar.

Antlar had just appeared in Sendai as the Japanese military is fighting the ancient Kaiju. Later, the monster scanner had picked up another monster containing nuclear energy was following Antlar as Starwoman and Starman were wondering what creature could follow Antlar as the computer comfirms it to be Godzilla Junior.

Things get more worst when Antlar finally reaches Tokyo while some people are escaping as everyone tries desperestly to defeat Antlar, but so far, Antlar was too powerful. Ultraman steps in and battles the magnetic monster, but even the giant alien was no match for Antlar as he was forced to leave Earth when his blinker was flashing.

Anguirus pops out from the grounds as the four legged dinosaur charges and knocks Antlar to the ground while the Shobijin were retreving the blue stone as they went back to Tokyo to give to the Gammas.

Although Anguirus could not beat Antlar, he lays out a roar which Starman realizes that Anguirus is calling out to another monster for help. Meanwhile, a blue light was glowing in the ocean and was heading straight for Tokyo Bay as anyone could see the dorsal fins of a giant monster as the creature reveals to be Godzilla Junior who's come to stop Antlar as the two creatures fight.

The Shobijin told everyone that Mothra Leo felt Antlar's pressence and contacts Godzilla Junior to stop the monster as Anguirus was sent to fight Antlar as a distraction. It seems that Antlar gain the uper hand until Godzilla Junior started to glow and evolves into an adult version of himself, much to everyone's surprise as Godzilla Junior continues to attack Antlar.

The faires give Starman the blue stone as he puts it in a laser gun that utilizes the stone's energy to create a laser beam to weaken Antlar and succeeded, Antlar was powerless as the Gammas and Unicorn attack the massive insect Kaiju.

In the meantime, Godzilla Junior defeats Antlar and kills the monster with his Atomic Breath, saving the world from Antlar's reign of terror. As the son of Godzilla goes straight into the ocean, Starwoman asked her husband what's going to happen now that Godzilla's son is the new "King of the Monsters" as Starman tells her and everyone that Godzilla Junior will help defend the Earth from other threats while they go home to rest as Vicky says it was the most epic giant monster battle ever.
