The opening volley came from the robot resembling a terran rodent, firing an oscillating beam of energy towards Mothra. Despite her best attempts to dodge it, she was struck dead-on. The violent energy coursing through her body sent her crashing into the ground. Disoriented, she flayed her wings helplessly before finally lifting herself back into the ground just as Moguera drew close enough to attempt crushing her. Its foot stomped the ground deftly, producing a cloud of dust as the giant butterfly swiftly lifted herself back into the air. Mothra did not feel herself otherwise injured, simply dazed from the attack. Distancing herself enough to minimize the risks from being shot again, she answered back with a few bolts of energy from her fiery blue compound eyes. Each strike hit home, leaving scorching indentations in the armored hull of the robot. However, Moguera seemed quite unfazed by the attacks, constantly moving towards its target despite the damage sustained.
Though Gezora was rather swift for a land-bound cephalopod, Godzilla was far too impatient to wait for it to reach him. Closing the rest of the distance in long strides of his bulking legs, Godzilla stopped just short of contact to bring his thick tail around in a heavy swipe. Tail connected with tentacles. The owner of the latter reeled back some, but it recovered just as quickly. Responding with its longest appendages, Gezora struck back with whip-like efficiency at Godzilla's snout. An irritating attack, Godzilla batted away the whipping nuisances while closing further to batter the giant cuttlefish with sharp claws.
Mothra continued peppering the mecha-mole while keeping her distance to evade Moguera's beam attacks. The machine, oblivious to the increasing damage, continued to track and follow her. Continuously firing its beams at Mothra, Moguera was steadily exhausting its power reserves. Its beak would eventually simply light up, but no beam would producing. The primitive AI of the machine could only continue to try charging up its attack in vain; meanwhile Mothra continued to chip away at its hull until the vulnerable was exposed. Sparks from its impending short-circuiting arcs of electricity began spurting out of its wounds. It was a leading game, Mothra lofting herself backwards to always keep a distance from Moguera while the robot continued to follow, oblivious of its impending demise. What energy reserves were left in the machine were focused on its mobility, legs moving at a faster rate while short arms swung at empty air.
Melee combat was a double edged sword, regardless of size. Godzilla was able to inflict gruesome tears into the flesh of Gezora, rending thick slabs of flesh and leaving behind bloody gashes. The cuttlefish, however, managed to fully ensnare the reptilian monster afterward with its thick tentacles. Wrists and ankles bound tightly, Godzilla thrashed and squirmed wildly. His dorsal fins ignited brightly, but the resultant blast of atomic breath was poorly aimed, largely due to Godzilla's thrashing. However, it still managed to sever a pair of tentacles. The torn portions of appendages writhed with lingering nerve pulses before falling off and releasing a wrist and ankle. Half freed, Godzilla's claws clutched Gezora's head to stabilize him, the razor sharp tips digging in deep. The cuttlefish's single blood red eye glowered blankly at its captive. It was not angry at Godzilla, or even wholly aware of it. All the creature knew was rage and its purpose. There was only rage, against everything, and a desire, to destroy everything.
As the barely functioning hulk of Moguera's body hobbled its way closer to its target, the beak continued to glow brightly, segments of its face plating chipping away under the strain of its primary weapon that continued to charge. Mothra's compound eyes brightened fully and a pair of energy bolts shot out. Instantly, the beams scorched through alien alloys as it were made of putty, leaving a gaping hole where Moguera's face once was. For a moment, Mothra believed the robot to simply continue on its unwavering route towards her, until suddenly the robot stopped. Metal limbs jerked in an acute spasm, the lifeless hulk producing a long whining sound of metal buckling as it fell backwards with a resounding thud. Sporadic sparks of electricity shot out of its fatal wound until the last remnants of energy were extinguished.
Godzilla's talons sunk in deeply into Gezora's body, keeping the giant squid monstrosity immobilized as the reptile's dorsal fins glowed brightly. His gullet flashed as the buildup of radioactive energy surged upward, spewing out hotly as Godzilla's maws opened wide to fire his atomic breath point blank at Gezora's body. The land-bound sea creature flailed in agonizing pain, tentacles thrashing wildly as every nerve was set on fire from the blast. Its pain would mercifully not last long. Flesh instantly went from bubbling to liquefying. Limbs going limp, the whole of Gezora's body seemed to deflate not unlike a balloon with a slow leak. Soon the monster was a gelatinous pulp with severed remains of tentacles twitching about the puddle. As the last of his breath escaped, Godzilla looked down at the results of his attack. He should have been pleased at the total destruction of his enemy, but he was not. His stare, from the remains of Gezora to Mothra and back again, was telling. Even he had believed it was far too easy. Gazing down at the goo that dripped from his claws, he shook them vigorously to clean them before approaching Mothra. She did not look any worse for wear than he did, he thought to himself as he looked over the robotic husk that had been Moguera.
"That was…," began Mothra, her chirping betraying the bit of exhaustion set on her from the fight. While the fight had not been particularly demanding, her beam weapon had been the only attack she had been able to use to damage the creature. The constant use of her beams had fatigued her some, especially while keeping to an almost unchanging distance to avoid Moguera's own attacks.
"Not Gezora," Godzilla growled out, squashing one of the severed tentacles. His immense weight immediately bisected the limb with a sickening squish, the tip of the tentacle jerking and twisting as final nerve pulses coursed through the segment. As powerful as he was, and as weak as he believed the real Gezora was, he had never been able to literally melt his opponent with a single blast of his atomic breath. He did not know what the creature he fought was, a clone perhaps. A glance at the robotic corpse did not help any, as they could just as easily face another of its number on another planet. The real Gezora was yet to be seen.
Mothra looked on at Godzilla in quiet contemplation, a bit surprised at his ability to think beyond a battle. If they did have to fight the others, those from their home, perhaps there was a comfort in knowing that they may well be fighting inferior clones. They could yet rescue their comrades. Before she could vocalize such an assurance to Godzilla, sirens ran along the Moon's surface.
Klaxons began to ring loudly towards the south-west, causing both guardians to snap their attentions towards that direction. The ground shook, massive metal walls sprouting from the very lunar soil as if artificial petals. Encompassing the alien base, the walls effectively turned the encampment into an enclosed fortress. Even from a distance, both could make out the extensive armament sticking out of the walls through various ports and slots, ranging from cannons to missile turrets. A heavy hiss could be heard further into the confines of the base, the tip of a structure rising out before it began to lift. The tip was the nose cone of a ship, the rest of the vessel rising up over the horizon of the protective ring of walls before taking to the newly formed atmosphere. Low enough to still be seen in its high altitude, the ship began a slow approach towards Godzilla and Mothra. Lights flashed along its hull, smaller lights sparking to light around it as the alien vessel began releasing its payload upon the guardians. Plumes of dust rose violently as their explosive warheads impacted nearby. With no choice now but to continue, Godzilla crushed the remains of Moguera's head beneath his clawed foot while Mothra flew swiftly ahead.
