【 プロンプト 】
A colossal mechanical kraken, its body a fusion of alien bio-technology and abyssal monstrosity, rises from the deepest trench of an alien ocean. Its smooth metallic plating gleams with an eerie bioluminescence, and its countless armored tentacles, lined with segmented, claw-like appendages, coil and thrash as it prepares to unleash destruction. Its massive central eye, embedded in a rotating metallic core, pulsates with unknown energy, scanning the ocean for prey. As alien warships resembling deep-sea creatures approach, the kraken’s tentacles extend, wrapping around and crushing them effortlessly, pulling entire fleets into the abyss.
52 . 機甲大帝・アビスティタン (Abyss Titan: The Armored Emperor of the Deep)

※ 生成AI : ImageFX
【 プロンプト 】
From the blackest depths of the ocean, an ancient titan reawakens, its slumbering form sending seismic waves that rupture the alien cities built upon the ocean floor. Neptus Omega, the god of the abyss, rises once more—its form so vast that even the light from the surface dims in its presence. Each motion bends the tides to its will, sending massive tsunamis that reshape the underwater landscape. Its gargantuan body is clad in an unbreakable shell of abyssal metal, formed from interlocking plates that resemble the carapace of ancient deep-sea predators. The titan’s exoskeletal armor, etched with glowing abyssal runes, pulses with a haunting blue light, illuminating the darkness of the abyss with an eerie, divine glow. Every inch of its indomitable form tells of forgotten wars, its plating still bearing the scars of cosmic battles fought eons ago. From its back, two enormous, translucent fins unfurl—wings formed from razor-edged metallic membranes, reminiscent of the fins of a colossal dragonfish. Each beat of these wings generates violent oceanic currents strong enough to tear apart submerged mountain ranges and erase entire undersea metropolises. The very water around the titan distorts, forming gravitational anomalies as if space itself is bowing to its return. Its most fearsome feature, however, is its colossal, crab-like arms—each limb a fusion of biomechanical perfection and abyssal monstrosity. Where once humanoid hands might have been, now exist two titanic pincers, their serrated edges gleaming with a terrifying, unnatural sharpness. These claws, each the size of an entire warship, snap shut with the force of a collapsing black hole, effortlessly crushing alien fortresses into dust. The outer shell of these claws is covered in pulsating, glowing ridges that channel energy from the depths of the ocean, allowing them to generate pressure waves capable of shattering anything in their path. The titan’s helm, crowned with spiraling abyssal glyphs, remains expressionless—an unfeeling, godlike enforcer of deep-sea judgment. Its eyes, twin abyssal voids burning with cosmic light, pierce through the dark waters like silent beacons of annihilation. Alien warships, built to withstand the crushing pressure of the deep, launch a desperate assault. Plasma torpedoes and railgun shells bombard the titan’s armored body, but the abyssal colossus does not falter. It raises one massive claw—a structure so vast it momentarily blocks out all light from the surface—and brings it down, unleashing a devastating shockwave that obliterates an entire fleet in an instant. The ocean churns as though the abyss itself has come alive, swallowing all who oppose its return. Neptus Omega is not a being of war—it is war itself, a mechanical deity built to command the tides, to erase empires, and to reshape the abyss in its own image. As it ascends toward the surface, the alien civilization above watches in horror, realizing that no weapon, no strategy, no act of desperation can halt the will of the abyss. The age of mortals has ended. The ocean belongs to the titan once more.

【 プロンプト 】
A monstrous, sentient war machine shaped like an enormous alien manta ray glides through the darkness of the abyss. Its body, made of interlocking mechanical plates and adorned with pulsating organic veins, stretches for miles, resembling a floating fortress rather than a single entity. Glowing alien glyphs etch themselves along its massive fins, creating whirlpools of dark energy wherever it moves. Instead of weapons, its body houses living drones, shaped like biomechanical lamprey eels, which detach and hunt down intruders in the abyss. The fortress moves with silent, calculated grace, a drifting horror of the deep that no one has ever seen and survived.

A mechanical dragon, designed in the image of an ancient sea god, awakens beneath a ruined alien palace submerged in an ocean of shadows. Its enormous, serpentine body is lined with overlapping metallic plates resembling the armored scales of prehistoric sea beasts. Its fin-like wings, translucent yet reinforced with glowing crystalline structures, propel it through the water with terrifying speed. Its head, crowned with jagged spires like the dorsal fins of deep-sea predators, turns toward an approaching alien fleet, its mouth opening to reveal an abyssal maw filled with rotating, crushing plates. As it moves, the very water around it warps, as if bending to the will of this ancient mechanical deity.

【 プロンプト 】
A nightmarish, battle-scarred mechanical crab lurks in the ruins of an ancient war, its massive pincers made of sharpened, segmented armor plates that can crush even the hardest alien alloys. Its multiple glowing eyes scan the battlefield with cold precision, detecting even the faintest signs of movement. Covered in the remnants of past battles, it moves through the ocean like a tank, its movements slow but unstoppable. The alien warriors attempting to deactivate the ancient war machine realize too late that it has already locked onto them, its armored legs shifting as it prepares to charge with the force of an underwater earthquake.

※ 生成AI : ImageFX
【 プロンプト 】
A massive alien warship, its design inspired by deep-sea creatures, emerges from the depths of the ocean. Its colossal, cephalopod-like form is lined with thousands of bio-mechanical turrets resembling the eyes of deep-sea fish, each glowing ominously as they scan for threats. Tentacle-like docking stations extend from its underbelly, releasing entire squadrons of smaller, squid-shaped fighter drones that dart through the water with unnatural speed. Unlike a traditional ship, the Abyss Void is semi-organic, its core pulsating like a living heart, adapting and evolving in real-time as it engages in battle.
59 . 深淵の幽影騎士団 (Spectral Abyss Knights)

※ 生成AI : ImageFX
【 プロンプト 】
From the deepest trenches of the ocean, an ancient order of knights long thought lost drifts once more into existence. Their return is marked not by war cries or battle horns, but by an ominous, ethereal glow, an unnatural bioluminescent storm forming in the abyss as they rise. They do not march—they float, their forms suspended in the dark currents, moving like silent wraiths through the void. Their mechanical armor, once forged for conquest, now resembles the haunting beauty of deep-sea jellyfish, their exoskeletons transformed into sleek, translucent plating that ripples and pulses with eerie energy. Their helmets, elongated and adorned with crown-like bioluminescent tendrils, obscure their faces, leaving only the faint glow of abyssal rune-marked visors to pierce the darkness. Long, flowing appendages—like the drifting tentacles of some cosmic cephalopod—extend from their backs, shifting as if submerged in an unseen tide, creating the illusion of trailing ghostly veils. Each knight wields a weapon resembling an organic fusion of coral and living metal—blades that seem to shift between solid and liquid, pulsing with phosphorescent light. Some bear elongated staffs, tipped with crystalline orbs that emit waves of distortion, causing the surrounding waters to tremble. Others carry spear-like lances, their edges dripping with shimmering, venomous energy that lingers in the water long after a strike. As they drift forward toward the ruins of their lost empire, they leave behind trailing echoes of themselves, afterimages of light flickering like deep-sea specters. Alien submarines patrolling the sunken cities attempt to analyze them, but their instruments fail—data becomes unreadable, as if the knights exist outside conventional space-time. Attempts to communicate are met with silence, save for the occasional whisper-like pulses that infiltrate comms systems, a language long forgotten. The waters shift unnaturally as the knights reach the heart of their ruined kingdom. Strands of mechanical tendrils, extending like jellyfish tentacles from their armor, weave through the broken structures, reactivating ancient monolithic obelisks that glow with cryptic abyssal inscriptions. The ruins breathe once more, as if the city itself has awakened to serve its lost masters. A final transmission reaches the alien civilization watching from the surface: “The ocean belongs to them now.” And then, silence.

From the crushing abyss of an alien ocean, a god-like mechanical dragon rises, its body stretching for miles, adorned with shimmering, interlocking metallic plates resembling deep-sea fish scales. Its massive dorsal fins, resembling jagged energy-laced wings, slice through the ocean currents with each powerful movement, generating tsunamis that engulf entire underwater cities. Its face is a terrifying fusion of an armored anglerfish and an ancient dragon, crowned with spiraling metallic horns that emit a haunting resonance. Embedded in its colossal chest is a rotating abyssal core, resembling a whirlpool of pure energy, devouring everything it touches. Its tail, ending in a cluster of massive, bladed fins, whips through the deep, generating rifts in the ocean floor. Alien warships resembling bio-mechanical leviathans engage the beast, but their plasma weaponry barely scratches its god-forged armor. The ocean trembles beneath its roar, heralding the extinction of those who dare defy its return.
