Day One: Escape from Monster Island
GDF Base-12:30 AM
Years had passed since the Vortaak's latest invasion, though Spacegodzilla had been soundly defeated, and the alien invaders were forced to flee, the Global Defense Force were sure to remain vigilante. Though as the years went by, things had been eerily quiet, the Vortaak wouldn't dare show their face after such a punishing defeat and even the Kaiju of Earth seemed relatively calm...too calm. But just as the GDF seemed put at ease, something appeared near Earth's atmosphere...
"Um sir, you may want to see this."
Commander Tagaki rushed over to his Specialist, Kenji Miku.
"What is it Miku?"
She pointed at her screen "Our lunar sensors have detected multiple objects heading straight for Earth."
"Are they alien ships?" The commander asked leaning forward.
"No sir, readings indicated that they are meteorites...hundreds of them." Her screen lit up with several red dots indicating the asteroids heading for several of Earth's major cities.
The Commander's face tensed. "Why didn't our deep space probes pick them up until now?"
"That's what's so strange, they just...appeared...materialized out of nowhere."
The Commander looked closer at the screen, taking note of the red dots advancing quickly towards the Earth. "They're heading straight for us, there's no time for counter measures." He turned to the others in the room. "Send out a global alert!" He bellowed to sending all the specialists scrambling. He turned back to Miku. "How long till impact?"
There was a then a massive tremor accompanied by an earth shattering boom.
"Does that answer your question?"
"Check on the monsters!" The commander ordered frantically. "The meteors may have damaged the force fields!"
Miku brought up surveillance of Monster Island. "The island's taken several small hits but...what a minute...something strange is happening!" The Commander leaned in watching as several strange structures began to grow from the impact zones. "It looks like some sort of...crystal formation."
The commander's eyes widened. "My god...I have a hunch the Vortaak are behind this, an invasion can't be far behind. But right now we need to keep the monsters from escaping the island."
Monster Island-8:30 AM
Monster Island, truly a godsend for humanity. The oddly beautiful island served as a home to a decent chunk of Earth's monsters who for the most part seemed content to remain on the island and live their lives without humanity to disturb them. Nevertheless, the GDF (ever so vigilante) took precautions to make certain the monsters who lived on the island remained there even placing an invisible barrier around the the entire island. Though this day it would seem the monster of Earth's peaceful lives would be disturbed once more.
The very ground rumbled as a thundering yawn echoed through the trees. It seemed the late night meteor shower had oddly enough, not roused The King of the Monsters in the slightest. Though as he shook his head trying to shake of the remaining grogginess, he couldn't help but notice the change in his surroundings. Encircling his den were several crystals, almost as large as him. Curious Godzilla straddled up to one of them, there was a strange energy radiating from them that seemed so foreign and yet...familiar to the King of the Monsters. However Godzilla's thoughts were interrupted as a cry seemingly of distress echoed through the air. Godzilla rushed from his den, taking note of Fire Rodan whom also seemed aroused by the cry. The duo soon arrived to the source of the cry, it appears that three large crystals had sprouted in the entrance to Anguirus' den, trapping the poor monster inside. Godzilla waisted no time, taking a deep breath, as stream of red atomic fire escaped his jaws, but much to his surprise, his signature atomic breath appeared to have no effect. In fact, the crystals completely reflected his atomic breath. Rodan attempted to dive bomb into the crystal barrier but even at his top speed, the barrier didn't budge. At that point Godzilla had decided that this task would require "the old fashion approach". Stepping up to the barrier he began striking hit has hard as he could. Rodan continued to strike it as well and soon the combined might of the two monsters was finally enough to shatter the barrier and free their friend.
Anguirus let out a roar in gratitude, but was interrupted as he noticed several crystals sprouting near the bay. Godzilla and Fire Rodan looked around watching as more crystals sprouted up at a feverish pace. Interestingly enough they weren't the only ones taking note of this development. Nearby Baragon emerged from his den, investigating the commotion he had heard earlier, Mothra slithered out of the jungle and even King Caesar appeared to have climbed from his little "stand" on the side of the mountain. The monsters all gathered observing this strange development then they noticed a particularly large crystal smash through the GDF island base, disabling the force field. Something wasn't right, it had been years since Godzilla had vanquished doppelgänger from beyond the stars but these crystals just didn't sit right with the King of the Monsters, and if these were what he thought they were, then the Earth, their home could be in great danger, and they'd be damned if they'd be stuck there while the Earth's in danger.
Sharing his concerns with his comrades (at least in his own way), Godzilla and his fellow Earth monsters knew what they had to do. Stomping over to the now exposed GDF base, the monster smashed the structures that had been keeping the barrier active, disabling the force field around the island. With a rallying roar Godzilla and his comrades began swimming out to sea. Though he still wasn't sure what it was, something about these crystals didn't sit right with Godzilla, and he felt that very soon he and his comrades would need to defend their home once more.
Author's Note: As you can probably gather, this story will mostly be following the POV of the Earth Defenders, though on occasion it will shift to the GDF and the Aliens (with a few Mutants from time to time)
