ALIEN FUTURE CITY 第08章

ALIEN FUTURE CITY 作品一覧

 

 

71 . 異形戦艦・メタリックスローン (Aberrant Warship: Metallic Throne)

※ 生成AI : ImageFX
【 プロンプト 】

A fortress-sized alien battleship, its form resembling a fusion of a deep-sea leviathan and an imperial dreadnought, drifts through the abyss. The ship’s outer hull is an amalgamation of shifting metallic plating and organic coral-like growths, giving it the appearance of a living entity rather than a constructed vessel. Its jagged, layered fins extend outward like a vast skeletal frame, lined with pulsing alien energy. Inside, no crew remains—only a self-aware AI, designed to wage endless war, its consciousness trapped within a vessel that has forgotten its purpose. As it moves, the ocean itself distorts, as if the void surrounding it is warping to its command. When it encounters foreign ships, the Metallic Throne does not fire weapons; instead, it extends spire-like tendrils that pierce and absorb the ships into its own growing mass, becoming an ever-expanding ghost fleet of mechanical horror.

 

72 . 沈黙する機械神・デウスネプチューン (Silent Machine God: Deus Neptune)

※ 生成AI : ImageFX
【 プロンプト 】

At the heart of an ancient, drowned alien metropolis, a titanic war machine lies dormant, its monolithic form fused with the remains of a forgotten fortress, its outer shell layered with shifting metallic plating and fossilized alien coral. The structure breathes, its engraved abyssal glyphs pulsing faintly, as if whispering to something buried within. Then—it awakens. The plated exoskeleton begins to shift, grinding against itself with an unnatural, insectoid precision. Armored segments unfold, revealing an ever-moving labyrinth of pulsing, biomechanical tubing, synthetic muscle fibers coiling like living tendrils. Its upper body, a towering fusion of deep-sea leviathan and machine, rises—its head an angular, expressionless visage, its spiraling metallic horns pulsating with cryptic signals, broadcasting a message that no living thing was ever meant to understand. But beneath the glistening machine plating, its true form uncoils. Where legs should be, an immense mass of mechanical tentacles slithers from the ruins, each appendage armored in segmented plating, covered in rows of retractable harpoons, serrated hooks, and drilling mandibles. These colossal biomechanical limbs, writhing like the feelers of an abyssal horror, move with an unnatural elegance, distorting the ocean itself, creating currents that break the laws of physics. The water does not flow—it is dragged toward the machine’s core, consumed like the very matter around it. In one of its colossal, clawed hands, Deus Neptune lifts a towering trident, its three serrated prongs writhing with jagged energy, covered in vein-like biomechanical conduits, flickering with dim, blood-red pulses. This weapon is not just forged, it is alive, shifting as if feeding on the destruction yet to come. Above, bio-mechanical warships, resembling colossal abyssal predators, detect the awakening too late. Their systems fail, their weapons malfunction, their hulls begin to corrode—not from age, not from attack, but as if the mere presence of Deus Neptune is rewriting their existence. The fortress-shell behind it, now emptied of its captive god, begins to collapse into itself, no longer able to sustain the entity it was built to contain. The spiraling ruins of its prison sink into the abyss, torn apart by the unstoppable pull of its awakening. Then—it moves. The tentacle-like appendages lash outward, wrapping around the wreckage of the alien city, dragging entire structures into its abyssal form, fusing them into its ever-growing mechanical mass. The trident lowers, and with a single movement, a gravitational pulse shatters the abyss, sending titanic shockwaves through the deep, bending the ocean into an impossible void. The alien researchers, watching from their submersibles, realize too late—this is not just a machine. It is the abyss itself, given form. And now, it rises.

 

73 . 深淵の幽魚・ダークシーヴァ (Phantom Abyssal Fish: Dark Seava)

※ 生成AI : ImageFX
【 プロンプト 】

A specter of the deep, neither fully mechanical nor fully organic, glides through the abyss, its shape ever-shifting between forms of abyssal predators. Its translucent, bioluminescent fins extend like glowing curtains, creating an illusion of ghostly wings that drift through the void. When approached, the creature’s body momentarily solidifies into jagged armor, its abyssal maw lined with interlocking mechanical plates resembling the jaws of ancient sea monsters. Unlike other creatures of war, Dark Seava does not attack—it devours. It moves through the water like a living shadow, its presence erasing all sound, all movement, all existence. Those who enter its territory do not fight it; they simply vanish, as if they were never there.

 

74 . 冥界機竜・ヘルリヴァイア (Underworld Mecha Dragon: Hell Leviatha)

※ 生成AI : ImageFX
【 プロンプト 】

An ancient draconic war machine, long buried beneath the ocean floor, emerges as the result of a seismic event. Its endless, coiling body, covered in a labyrinth of alien runes and armor plates resembling deep-sea scales, moves with calculated precision. Its massive, bladed fins, stretching like abyssal wings, create currents so powerful they rupture the very fabric of the ocean. Alien warships fire their most advanced weapons, but nothing leaves a mark—Hell Leviatha is no ordinary construct. It was built to be indestructible, a force of war that no civilization could control. As it ascends, its gargantuan silhouette blocks out the remaining light, and the alien metropolis above is cast into eternal night.

 

75 . 殲滅機甲魚・クルーエルバラクーダ (Annihilation Biomechanical Warfish: Cruel Barracuda)

※ 生成AI : ImageFX
【 プロンプト 】

A hyper-aggressive, bio-mechanical war machine, designed in the form of a massive barracuda, patrols the abyss with relentless precision. Its streamlined, armored frame, composed of countless intricate mechanical parts, allows it to move at impossible speeds, its jagged, energy-infused fins slicing through the water, generating sonic booms that rupture the seabed as it propels forward. Its eyes—glowing slits of burning crimson—lock onto prey before they even realize they’ve been seen. The moment it detects movement, its internal systems surge with abyssal energy, and its mouth begins to open, revealing a shifting, serrated mechanism, lined with glowing conduits of raw destruction. Then—it fires. A concentrated annihilation beam erupts from its gaping maw, a spiraling torrent of molten energy, tearing through the abyss like a spear of pure entropy. The beam does not simply pierce—it disintegrates, reducing alien submarines to molecular vapor, their reactors collapsing before they can even detonate. The ocean itself distorts, a shockwave of obliteration expanding outward, as if the abyss is recoiling from its own executioner. Alien vessels attempt evasive maneuvers, but Cruel Barracuda’s AI has already calculated their paths before they even move. It does not hunt. It does not hesitate. It simply erases.

 

76 . 異形機獣・ヴァイラルハイドラ (Aberrant Machine Beast: Viral Hydra)

※ 生成AI : ImageFX
【 プロンプト 】

A terrifying biomechanical mutation, once a weaponized alien war machine, now a grotesque fusion of flesh and machine, prowls the abyss. Its three writhing heads, each a twisted amalgamation of deep-sea predator and cybernetic construct, pulsate with glowing infection tendrils, spreading a self-replicating virus into the water around it. Its armor, once sleek and refined, is now fractured and uneven, growing like a living parasite, shifting with each movement. Its many bladed fins, resembling jagged bio-metallic appendages, allow it to twist and contort impossibly, moving in ways that defy physics. When it finds prey, its central maw splits apart, revealing a swirling void of nanite-consuming energy, a living black hole that digests both organic and mechanical matter alike. No escape. No cure. Only assimilation.

 

77 . 殲滅戦鬼・エクスキューションダイバー (Abyssal Executioner: Execution Diver)

※ 生成AI : ImageFX
【 プロンプト 】

A gigantic alien-operated mech, resembling a monolithic humanoid, stalks the deep, its multi-layered armor resembling the skeletal plating of an abyssal giant. Piloted by a grotesque, cephalopod-like alien, wired directly into its control system, its organic neural pathways fused with the machine, allowing it to move like an extension of its pilot’s own twisted body. Its right arm is a massive harpoon cannon, launching electromagnetic spears that pierce and tether enemy vessels, dragging them into the abyss. Its left arm, a serrated bladed appendage, twitches as if anticipating its next kill. The pilot, encased in a transparent neural fluid chamber, twitches as it issues commands, its multiple tendrils pulsing against the interface, manipulating the mech with inhuman precision. It does not fight for survival. It fights because it was made to kill.

 

78 . 異端融合体・ゼノグリムリーパー (Xeno-Hybrid Executioner: Xenogrim Reaper)

※ 生成AI : ImageFX
【 プロンプト 】

A failed experiment—an alien consciousness forcibly fused with a machine—stalks the ruins of a long-dead civilization. Its elongated form, a mix of serrated exoskeletal plating and exposed, sinewy alien muscle, moves erratically, unpredictably, its twisted AI and biological instincts warring for control. Where its arms should be, long energy scythes form and dissolve, flickering between matter and energy, shifting between hard-light constructs and living appendages. Its head, once humanoid, has split into multiple segments, revealing a writhing mass of mechanical tendrils, each one acting as a sensor, a weapon, or a mouth. It does not recognize friend or foe. It only knows one directive: consume and evolve.

 

79 . 旧き海の終焉神 (The Doomsday Deity of the Ancient Ocean)

※ 生成AI : ImageFX
【 プロンプト 】

A formless biomechanical entity, once a failed deep-space war machine, now an endless shifting abomination, drifts in the abyss. Its body is not solid, but an ever-shifting mass of metallic tentacles, jagged fins, and hollow, whispering exoskeletons, constantly reforming into new, grotesque configurations. Its central core, a pulsating, colorless sphere, distorts time and space, creating fractured echoes of its own body, causing its enemies to see multiple versions of it at once, all equally real. When it attacks, it does so from all angles, from every possible iteration of itself, striking in ways that should not be possible. Its victims do not scream. They simply vanish—as if they were never there at all.

 

80 . 封印戦鬼・ネザーマリオネット (Sealed War Demon: Nether Marionette)

※ 生成AI : ImageFX
【 プロンプト 】

A towering humanoid machine, kneeling in the depths of an ancient, submerged battlefield, remains motionless—a lifeless effigy of war, forgotten and entombed beneath the abyss. Its sleek, cybernetic plating, once thought to be the pinnacle of advanced war mech engineering, is nothing but a shell, a containment vessel for something far worse. Above, massive, biomechanical chains, pulsating with alien script, descend from the abyssal void, embedding themselves into its armor, tethering it like a puppet to an unseen master. These chains do not bind—they command, restraining the nightmare within, forcing its body to remain subservient, despite the unnatural twitching of its limbs, as if it longs to break free. Inside, something stirs. A monstrous alien entity, its twisted, chimeric form bound within the mech’s plated exoskeleton, is not dead—it is dreaming. Its mind, locked in a forced simulation, drifts through endless war, reliving destruction over and over, as the machine moves like an enslaved god, controlled by something that dares not let it awaken. Then—the first crack forms. The pristine plating fractures, revealing glimpses of writhing biomechanical tissue, a fusion of living flesh and synthetic horror, desperate to escape its prison. The chains strain, twitching as if aware that their grip is slipping. The moment its containment fails, the mech’s polished, artificial form will rupture, revealing the true horror beneath—a nightmare of flesh and machine, a war entity bound by broken programming and an insatiable hunger. There is no escaping it. There is only delay.
