The Arrival of Monster Kings

In the city of Tokyo, in the Ginza District, JSDF soldiers were making a hasty defensive line. Many are scrambling for more equipment, soldiers, and attack vehicles. After a massive roar bellowed from the gate, something massive was coming through it. A large, circular defensive perimeter was set up around the large archway.

Civilians panicked as hysteria and paranoia swept the city of Tokyo. Public authorities and the JSDF evacuated as many civilians as possible out of Tokyo.

On the defensive perimeter, soldiers and attack vehicles expect the kaiju's arrival. Whatever comes through the gate, they will destroy it to protect their country. The JSDF base from the other side of the gate hadn't responded to any calls. The High command assumed that the kaiju had destroyed before they had a chance to report back. All JSDF soldiers at the defence perimeter are tense and nervous. Some are sweating from nervousness. Others are thinking about their relatives, wondering if they got out of the city in time. Type 10 and Type 90 tank gunners had their finger on the trigger, ready to fire the moment the kaiju stepped through the gate. Kawasaki O-H 1 attack helicopters hover in the air as their missiles and miniguns aimed directly at the archway's opening. Military Toyota Mega Cruiser vehicles, armed with surface-to-air missile launchers and mortars, prepare for the attack. Type 99 155m and M110 self-propelled artillery at the rear provide extra firepower. All are ready to fire at a moment's notice.

The ground began to shake as the kaiju beyond the gate stomped through. JSDF soldiers started to get paranoid and were tempted to run, but orders from their general had prevented from running in fear of being court-martialed for desertion. Vehicles shake as the kaiju stomped through the gate. The shaking became stronger as it drew closer to the exit. Rory Mercury was also at the defence perimeter, wanting to battle the kaiju itself despite Itami's protests. Itami and his group, minus Rory, are currently being taken to safety on a military jeep to ensure the safety of the Falmartian princess and the other Falmartian visitors.

The shaking became more violent as the kaiju drew near. Three heads came through the gate alongside a golden dragon body covered in golden scales with two massive golden wings with hooked claws at the end of each fold on the back and two tails. The kaiju walked with its golden wings on the ground to support its body weight. The three-headed dragon observed the city and saw the JSDF. It roared as the military opened fire every gun onto the kaiju.

Ghidorah

After two years of hibernation within the Falmartian mountains, Ghidorah's body grew with his wingspan growing up to 225 metres long and reaching a height of 159 metres tall. On his wings, he grew hooked claws on the end of each fold. Ghidora's bio-electricity became stronger as his scales became more conductible to electricity, enabling him more ways to use his bio-electricity. His gravity beams became stronger in correlation to his scales' electric conductibility. Both of his body and legs became more muscular with muscle tendons on his wings became hyper-tensile, making him fly faster. Ghidora's regeneration also became stronger and faster, allowing him to regrow a head or heal his injuries.

Reaching the giant structure, he spotted a human settlement near the structure that was more advanced than the civilization of this planer. The humans saw him and began firing at him with their weapons, with no effect. He wiped out the settlement with his three heads blasting their Gravity beams, leaving no survivors. After destroying the encampment, he stomped towards the large archway, lowering his head to avoid bumping the upper part.

Inside the structure, he walked through the black void within it before seeing the light at the other end. When he emerged from the void, he saw a large city with tall buildings similar to the other civilizations he destroyed. At the exit of the structure, he sees a human army aiming their weapons at him, assuming they mounted a defence upon his arrival. To him, he had no concern because wherever he goes, resistance is futile. Different weapons from vastly different civilizations did not affect him, whether they're primitive or advanced.

"TSCHKOAOOOOOOO!" Ghidorah roared as every human weapon aimed towards him opened fire. All matter of projectiles, ranging from small to large, struck his body but did not affect him. He began firing his Gravity beams wildly towards every direction. The lightning struck the buildings and the ground. The Gravity beams obliterated some of the humans' contraptions, leaving only smoking rubble behind. The golden lightning burnt many human soldiers; only ash remains after the lightning struck.

Soon, the human army retreated after knowing it was a futile defence. Some soldiers and contraptions kept firing as they ran away. Ghidorah stomped through the city while blasting his Gravity beams in every direction. Civilians, who haven't evacuated yet, were either crushed by falling debris or obliterated by the lightning. Buildings reduced to rubble by blasts of his Gravity beams.

"TSCHKOAOOOOOOO!"Ghidorah roared in triumph as he continued to destroy the city and decimated the retreating human army.

Suddenly, something hit him from his back. Scorching heat burned his back with his scales darkening from the searing heat. He turned to confront the new adversary. The new adversary was a giant lizard with sharp dorsal plates that go from its back to its tail. It had charcoal grey skin with its scales having the same colour. The lizard had sharp, four-digit claws on its arms; And three-toed feet on its muscular legs. Its face bore a menacing and angry look, bearing fangs and rows of sharp teeth in its mouth.

"SKREEEEEEEEONGK!" The lizard roared, challenging the golden dragon.

"TSCHKOAOOOOOOO!" Ghidorah roared back, ready to fight the lizard kaiju.

3rd POV

It was a disastrous day for the JSDF. Many soldiers died as Ghidorah fired his Gravity beams. Their attack vehicles destroyed after a single blast of lightning. The commanders ordered a full retreat once they knew the defence was hopeless. Some were still shooting at Ghidorah, even if they knew it would do nothing to him.

In a JSDF building on the outskirts of the city, Itami and his group watched Ghidorah's rampage through the news coverage on TV.

"I am here live at the scene where the JSDF are fighting against King Ghidorah!" the field news reporter said, riding the news helicopter. They are broadcasting the battle throughout Japan.

"The JSDF is fighting fiercely against Ghidorah with everything they have." the reporter said, "The JSDF is now in full retreat after sustaining severe casualties! They are now focusing their efforts on evacuating the city before Ghidorah could do more damage!"

The camera showed the JSDF at the defence perimeter surrounding the gate retreating, some tanks and helicopters still fired at Ghidorah. Ghidorah continued to fire his Gravity beams wildly, striking buildings and unlucky civilians in the city. Piña and Bozes, having experienced this event before, are having traumatic flashbacks when Ghidorah destroyed their home. Itami and his comrades are seeing what the Godzilla films portrayed, the destruction of Tokyo by a kaiju. They are now thinking about what will happen in the future. Will Ghidorah destroy humanity, just like how it did with countless civilizations? Will world leaders get desperate and launch nuclear bombs at Ghidorah? Will nuclear fallout kill all of humanity entirely?

Suddenly, a stream of blue fire struck Ghidorah at the back, scorching his golden scales. The TV showed Ghidorah facing his new opponent.

"I can't believe it! Another kaiju passed through the gate!" the camera pans out to show both kaiju at the same time. "It's Godzilla! He has come to fight Ghidorah!" the news reporter shouted in shock.

The news showed Godzilla in his Heisei design but with sharper dorsal plates, standing at a full height of 120 metres with a length of 200 metres. All of Japan is shocked to see Godzilla. Many are now fearful of Godzilla, knowing none of humanity's weaponry can harm him.

Itami and his comrades are shocked to see Japan's most famous kaiju appearing through the gate. They are going to witness a battle between Ghidorah and Godzilla again, this time it's real.

"After this, the Anti-Kaiju military joint, G-Force, might form." Itami grimly said to his friends. The others thought of the same thing after Itami said it.

Both kaiju roared at each other, each anticipating the other's attack. A fight will soon happen within the city of Tokyo. Nobody knew who will win at the end and how much damage the city will take.

Soon, the fight between the Supreme Ruler of the Cosmos and The King of the Monsters will begin.

That's chapter six of this story! The battle between Godzilla and King Ghidorah will begin next time. In this chapter, I made Ghidorah a bit more like his Monsterverse incarnation after seeing what it could do.

And as always, don't forget to leave a review as it helps me write better!

See you next chapter!
