The whole of the Moon shook as the alien fortress readied itself for the kaiju siege, its defenders watching the inevitable approach of Godzilla and Mothra. They charged through the thick clouds of dust and debris kicked up the base's orbital defender. However, it was unable to stop the Earth guardians from reaching their objective. Thick metal walls groaned under the stress of repeated blows of Godzilla's thick tail. Incessantly slamming his appendage against the fortress, he gradually bent the primary wall back enough to begin prying it apart with his claws. Shredding the walls apart as they were not unlike wet tissue; Godzilla heaved pieces of scrap at the swarms of defending vehicle that zoomed and zipped around him while his female companion did her best to keep the remain alien spacecraft occupied. A stray bolt clipped her body, bringing the giant butterfly crashing atop a radar dish that immediately crumpled beneath her weight. To her surprise, Godzilla stopped to swiftly turn to where he had heard her fall. With widened eyes he looked at her fallen form, Mothra's antennae twitching before her head lifted to look back at him. He began to rush towards her, swatting several alien flyers out of the air with one hand and catching one in the other before crushing it.
"Don't stop!" called out Mothra to him. She tested her wings briefly before gradually lifting herself back into the air to reassure him, "I'll be fine." She could not recall a time she had actually encouraged Godzilla to continue his reckless and destructive path, or when he seemed to be concerned with anything other than destroying everything in front of him. For a moment, she watched him, hesitant in his movements before grunting and turning away to return to the task at hand. Her underside of her carapace felt tender, where she had been struck, but the Mothra followed after Godzilla to continue providing him with long-range aerial support.
The deeper Godzilla progressed into the enemy base, the more it seemed that the design of the gargantuan structure revolved around defending against giant monsters, particularly ground-based ones. Whole portions of the wall would jut out to create impromptu barricades meant to hinder while further wall panels jettisoned to expose even more weapon systems. Missiles impacted against his thick hide while lightning bolts scorched the superficial layer of scales. Some weapons did not even have the luxury of firing a first volley before a tail or claw would smash them back into their wall slots with brutal efficiency. Nothing the would-be invaders could muster managed to slow the reptilian kaiju, let alone stop him.
Smoking from the relentless attacks on his towering form, Godzilla lumbered menacingly closer to the final line of defense. In one single synchronous attack, all weapons fired upon both Earth guardians at once. While Mothra would weave and dodge her way into range of counter attack, Godzilla merely took his hits, even reeling back at times when heavier shots impacted against his abdomen or muzzle. Suddenly, he came to a stop, just as the alien weapons were going through a reloading cycle to fire another volley. As tendrils of smoke spewed from exhausted weapons, the whole of Godzilla's dorsal spines lit up. His maws parted slowly before he unleashed a radiant blast of radioactive energy. As portions of wall became molten slag to drip and seep directly into the weapon slots, the majority of defenses in Godzilla's immediate vicinity were unable to function further.
What few surviving forces remained abandoned their posts to make a hasty retreat towards the transporter. There were no further lines of defense to establish, no last stand to defend. The lunar monolithic structure hummed to life as scores of alien vehicles and transports reached their designated gathering points, panicking as Godzilla's wrath drew closer. The tip of the alien transporter flashed repeated, each time firing a blinding beam at the groupings of retreating invaders until all survivors were evacuated. There was only silence on the Moon afterward, save for the methodical and thundering footfalls of the giant reptile. Mothra cautiously circled the ruined base, her compound eyes tracing the landscape for any movements, any remaining pockets of resistance.
"That seems to be the last of them," Mothra chirped warily to Godzilla as she flew overhead.
"What now?" he grunted back, careful in his approach to the abandoned transporter. The sides of the structure continued to glow, powered by the generators that had remained untouched during the siege.
"A moment," she replied, softly landing on the ground beside him. The transporter reflected in each of the individual hexes of her compound eyes as she relayed the situation to her companions on Earth. She fell silent and still.
With his usual impatience, Godzilla growled out and began pacing around the central site of the base. Trampling various wreckage underneath his clawed feet, he even went so far in expressing his displeasure in waiting by picking up a large piece of scrap and heaving it. The alien vehicle took to a fast acceleration but a slow descent as it came to land almost near the outermost perimeter of the base. It hit with a satisfying thud that brought a sinister grin to Godzilla's reptilian muzzle. Looking aside to Mothra, he found her to be nonreactive to his antics, as if she were worlds away. He would be mostly right, as her mind was not truly on the Moon anymore. Huffing out in irritation, Godzilla squatted beside her before shifting to sit properly. His tail swishing in slow rhythm, he watched the distant Earth with a frown on his scaly brow as Mothra's wings gently beat against the lunar dust.
His waiting would not be long, as soon enough, she was on the move. Hovering over towards the transporter, Mothra said nothing as she drew herself closer to the adjacent module from where the aliens controlled the device. From Godzilla's perspective, she seemed to be doing nothing. However, she was being used as conduit between the device and her shÅbijin. As the priestesses received instructions on the controls of the transporter, they passed the information on to Mothra, using their considerable telekinetic abilities through their guardian to calibrate the device. Godzilla growled as the ominous device hummed menacingly, as its counterpart had done before on Earth.
"Be at peace," came a soft, and reassuring chirp from the female guardian, her eyes aglow as she continued to work out the controls of the transporter. So much she did not understand about it, or the aliens that built it. It was not her concern to know, she reminded herself to remain on task. The device was a means of stopping the invaders, nothing more.
Indignantly, her companion growled out and brought himself to stand once more. His claws flexed anxiously as if preparing to do battle with the device, should it backfire and attack them. He would not allow himself to be captured like the others.
"It is ready, Godzilla," Mothra answered, her eyes returning to their usual serene hue. Beating her wings gently to lift herself, she drew herself over towards him. Cautiously, she glanced his way, noting the narrowed reptilian eyes that glowered at the device. He had a right to be so. Though she trusted her priestess wholly, she did not know exactly how the alien structure worked, and that made her just as wary of it as Godzilla. As lights along the spine of the transporter lit up, climbing inexorably higher up the metal skin to signal its countdown, she looked over Godzilla's shoulder, towards the Earth. It may be the last time she would be allowed to see her home.
The wistful expression on her was lost on Godzilla, whose sole focus was the transporter. His legs tensed, knees bending slightly and tail flaring outward in a defensive stance. Maws opened partway; smoke seeping out between his fangs. He would not be caught unawares again by the alien beam. The apex of the device lit up brightly, so much so that the giant reptile hissed out in annoyance. His head jerked aside as if struck violently, a hand coming up to shield his eyes. It was of no use, however. The intensity of the light grew brighter still, encompassing the immediate area. Through and around his obscuring palm, the light seeped and bent around to force Godzilla to close his eyes. No amount of darkness could escape the light, and the king of monsters would know nothing more but the light as it absorbed the last guardians of Earth.
