Monster Island was quiet. He did not like it. Before, the island was filled with the disharmony of the calls of the various inhabitants, a melody all its own if Godzilla ever cared to admit such sentimental drivel. Now, there was nothing but the caw of tropical birds in the trees. As Mothra hovered nearby at shoulder height to Godzilla, he growled out deeply.
"Gone."
"We can bring them back," she chirped back to him.
He snorted back at her and proceeded further into the island, his massive frame snapping trees in his wake. Godzilla's ire was clear as each step shook the ground, soon to be directed at his true enemies. Mothra followed after in quiet contemplation, her thoughts of deception continuing to plague her. Godzilla was not wholly an ally to her, only when their goals or motivations were similar enough to warrant cooperation. But he was by no means an enemy either. A weary chirp was expelled, out of earshot of Godzilla. Lying was not her way.
There was life on the island, but no longer of the monster variety. The humans were industrious at their task. Bivouacked around the device, they had set up a wealth of structures. With thick and heavy cables leading from each, towards the monolithic transporter, they were presumably for the purpose of providing power to it. Godzilla's thunderous footfalls, each one progressively closer, were enough to bring the human activity to a halt. The sparse security, sparse in regards to what was necessary to ward off a single kaiju, let alone Godzilla, directed itself towards the two approaching creatures. Tanks turned their turrets, soldiers raised their rifles. Several hundred feet away, Godzilla and Mothra paused, the latter coming to gentle landing beside her reptilian companion. The distinct rumble of an engine approached the pair, a jeep popping it out of the tree. As it came to stop nearby, two humans stepped out, one man, one woman. Held out in the woman's cupped hands were the two shōbijin. In a soft chant, they greeted both Mothra and Godzilla before speaking in a manner that the two humans would also understand.
"We are forever in your debt," the tiny pair spoke out in unison. The humans followed suit by bowing deeply and graciously to the kaiju.
Godzilla replied by roaring, as was his way. Even from his great height, he took notice of the way the two humans tensed. It pleased him to see the humans shudder in fear, yet still keep up their submissive postures to him for several moments longer. Mothra's reply was a soft chirp that conveyed a sense of reassurance, enough so that the humans eventually straightened their backs once more to look up at the giants.
"Everything is almost ready," said the male human, his long white coat marking him as one of the scientists, if not the director of the project himself. His tone of voice, wavering though it might be in light of the situation, retained a sense of conviction. "Please," he motioned for Godzilla and Mothra to follow as the director and his partner climbed back into the vehicle. Together, the group made their way towards the center of activity. The monolith device was no longer as sleek or as pristine as Godzilla remembered it, the surface of exotic metals blemished by countless cords and cables forcibly inserted into the alien electronics found within. For Godzilla, it reminded him of a colossal mechanical cuttlefish. The name Mecha-Gezora came to mind, and the male kaiju rumbled out what could have been understood by the others around him as a throaty chuckle. The humans were unsettled by it. Mothra could only look at him oddly, an antenna rose in curiosity to the abrupt sound. She did not even think he was capable of a chuckle, much less humor of any kind. Regardless of his reason for it, the sound did please her.
Once both kaiju stood before the monolithic structure, the director stepped out of the jeep once more, this time with a megaphone. "All of humanity will be in your debt, Godzilla, Mothra," he began, "You are the only we have against defeat." His hand waved toward the alien device, directing the monsters' eyes towards it. "The plan is simple, but the goal will be by no means as simple. Both of you will step forward once the device is activated, and you will be sent to the nearest enemy base. Hopefully, you will be teleported beside the companion transporter. Eliminate any enemy forces you encounter and occupy the transporter. Mothra will remain in contact with us through her priestess, and we will direct her how to activate the device in order to continue to the next alien fortification. Your mission will conclude when you reach and conquer Planet X, forcing the invaders to surrender."
Godzilla grimly stared at the transporter. With a conceding grunt, he nodded to the humans. A growl was sent Mothra's way. Through her, the shōbijin translated Godzilla's growl to the director.
"He wishes to know how they will be returned to the Earth after."
A hesitant glance was cast between the man and woman, each one unsure of how to answer it without endangering the plan. It was the latter who answered, "It is our understanding that just as it was used to send off the others, and will be used to send you and Mothra forward, it should be able to send you back as well." It was not wholly a lie. Should and could were similar enough. The transporter should be able to function in reverse, even if they had yet to figure out how. The humans held their breaths, all eyes on Godzilla as he seemed to scrutinize the woman and her answer for several long heart-wrenching moments.
Panicking soldiers frantically cocked their weapons and raised them at Godzilla as he unleashed a long and resounding roar. Even the shōbijin winced at the shockwave produced before tentatively translating from the humans.
"He is ready."
The site was once more a beehive of activity, everyone scrambling to get the device fully operational before the lunar forces of Planet X arrived, or Godzilla changed his mind. The hours passed and daylight steadily slipped by. Anxiously, the reptilian male stared towards the first glimpses of stars as he waited on the western shoreline, the sun approaching the horizon. He despised waiting, for anything. Mothra could sense his growing anxiety and communicated with her priestesses to alert them, and the humans, of their shortening time.
"They are almost ready, Godzilla," she said to him, "We should return to the-"
Her thoughts were cut off by compound eyes snapping upward to the increasingly visible stars peppering the sky. 'There are far too many stars,' she thought to herself, even if they were far away from the human cities. It was an ill omen.
A distant cry rang out, "CONTACT!" Instantly, sirens were blaring all around the island as many of the so-called stars broke formation, scattering like so many luminous petals drifting along errant breezes. From the opposite side of the island, flashes broke out and streaks went sailing past as the joint human armada fired into the oncoming invasion force with both artillery and aircraft of their own. The sky was soon ablaze with explosions as the two forces met. The battle yet too far away to endanger the test site, the human pilots were under orders to keep it that way. Nothing was more crucial than the device and the kaiju it was to transport. Godzilla immediately pounded the earth with his mammoth feet, eager to fight and a little envious of the pitiful humans who were allowed to engage the invaders, while he yet could not. A fierce nudge against his flank drew back his attention.
"We must go, now," Mothra chirped at him sternly before flying on ahead.
Disgruntled still at yet again having to wake, Godzilla quickly lumbered after Mothra as the clashing of war drew ever closer to the island. Over the ocean, there were increasingly less and less flashes as the humans were overwhelmed by the superior numbers and technology of the alien invaders. Time was running out. Tanks and anti-aircraft vehicles rolled towards Godzilla and past in a desperate attempt to buy more time for the pair. He briefly watched them go, though it pained him not to crush the human vehicles. With nightfall darkening the island, save for the lights from the various battlegrounds now sprouting all over the island, the newly powered alien transporter became the brightest beacon for miles around.
It was the beginning of utter chaos. Having decimated the primary human air and ground forces, they had already begun converging on the site. The remaining forces had formed a last line of defense around the beacon. Seemingly disinterested in the beacon itself, the alien spacecraft avoided directly firing on the largest target in favor of picking off the defenders. It was not until the device uttered its ominous hum that the aliens momentarily ceased fire, zipping past in tight circles around the site as Godzilla and Mothra arrived. The invaders then realized the humans' intrepid plan. Godzilla roared at still stunned enemy, fins instantly igniting in blue energy before he bathed a squadron of spacecraft with deadly radiation, melting some of them outright. Pulps of molten metal careened into the ground while the remaining spacecraft separated into two distinct groups. One targeted the two kaiju while the other began their assault on the transporter.
Godzilla reveled in battle long-awaited, thrashing wildly with his tail and slapping spacecraft out of the air. Mothra would not allow him to enjoy his fun for long, not with the device now being in danger of being destroyed. Already a few of the power structures exploded while the device itself was sending off sporadic arcs of lightning into the air. He was only allowed one more atomic blast from his maws before she suddenly and unceremoniously scooped him out of the air. Latching her claws into both of his shoulders, she forcibly hauled him towards the device while dodging attacks. Through her strained flight, she was in constant communication with her shōbijin. It was now or never.
Struggling to keep aloft while avoiding incoming fire from the surviving spacecraft, Mothra nevertheless received a few grazing bolts of energy along her thorax. A pained shriek spilled as she released Godzilla, the momentum of her flight combined with his enormous mass sending the male barreling down the remaining distance until he ended up on sprawled on his back in front of the transporter. As she noticed that Godzilla was more or less uninjured, she drew her wings back and dive-bombed her way straight at him to reach the target zone of the device as quickly as possible. Godzilla did not have a chance to react before suddenly feeling a great weight slam fiercely into his abdomen, ripping out a pained roar out of his lungs as the impact produced a thick and obscuring cloud of dust and debris. The tip of the device sparked to life and shot a blinding beam of light into the cloud. As the dust settled, the last of the kaiju were no longer there. The remaining humans cheered in celebration, only to have their revelry torn apart as the transporter soon buckled from the heavy damage it had taken as well as the strain of firing its beam. Cries of panic ensued as everyone ran from the epicenter. Larger and brighter arcs of electricity wafted into the sky as the luminous beacon rivaled daylight. In an instance, the device was gone, not a single trace left of it save for the smoking crater where it once stood.
Amongst the smoking ruins, the surviving humans began to emerge to look over the devastated island. The alien spacecrafts were nowhere to be seen, but there were no cries of joy or cheers. The device was gone, and they had no way of knowing if Godzilla and Mothra had even arrived safely. Somewhere in the ruins, a pair of voices could be heard, soft and dulcet. As their song began, all eyes looked to the stars, their hopes and prayers now resting on their guardians.
"Mosura… ya… Mosura…"
