Flashback...
Marcus felt the tremor three days before the creature surfaced.
It began as a low, subsonic growl through the soles of his bare feet while he stood on the tallest ridge of the monument range he had carved over the decades.
The sol shard in his chest pulsed once in answer.. curious, not alarmed. Kal's orb, back at the distant pod, confirmed the reading: anomalous bio-signature rising from a previously sealed Hollow Earth vent cluster two hundred kilometers north.
Mass estimate: one hundred and forty meters at full extension. Radiation signature: familiar but distorted. A Godzilla offshoot.
Stronger than the weak variants he had sparred in recent years.
This one carried the proto-alpha lineage more purely, its cellular furnace already burning hot enough to leak blue plasma through the crust.
He did not rush. The years had taught him patience. Fifty years of kaiju encounters had turned fights into measured calibrations.
Some he killed cleanly for the isotope-rich cores that fed the multiplier.
Others he spared when they proved they were simply guarding territory in the slow, dark balance of this young world.
This one felt different.
Hungry in a way that might tip scales.
On the third dawn, the desert split open.
A volcanic caldera Marcus had never visited before erupted, not with lava, but with a roar that shattered glass dunes for thirty kilometers.
Black basalt and glowing crystal exploded outward as the creature rose. It was magnificent in its primordial terror.
One hundred and forty meters of obsidian-scaled muscle, dorsal plates jagged and incomplete but already flickering with contained atomic fire.
Its eyes burned molten gold, heavy-lidded like the true proto-Godzilla he had touched decades earlier.
The tail, thick as a supercontinent ridge, lashed once and carved a new canyon. This was no weak offshoot.
This was a rival prince, stronger than the others, perhaps a direct sibling line that had fed deeper on the blue crystal vents.
It sensed him immediately.
Marcus stood motionless on his ridge, black fatigues whipping in the sudden wind, dark skin drinking the yellow sun that had just crested the horizon.
The creature's head swung toward him, nostrils flaring at the solar radiation bleeding from his body like a second core. It roared, a sound that vibrated through his bones and made the sol shard sing in resonance.
Challenge. Territory. The same instinct that would one day make Godzilla the apex.
Marcus answered by stepping off the ridge and walking forward. No flight. No heat vision.
He wanted the ground fight first. The soldier's way. Slow. Personal.
The kaiju charged.
Its footsteps shook the planet. Each impact sent shockwaves that toppled distant rock formations Marcus had placed centuries ago in his own training.
It covered the distance in twelve strides, jaws unhinging to reveal rows of crystalline teeth dripping superheated plasma.
Marcus met the charge head-on.
The first impact was deliberate. The creature's snout slammed into his crossed forearms like a living mountain.
The collision created a crater three kilometers wide and sent a dust cloud boiling into the stratosphere.
Marcus's boots sank half a meter into glassed sand, but he held. Bones denser than any metal in this world did not break.
Pain registered.. deep, grinding, the kind that reminded him he was still flesh beneath the godhood.
He absorbed the kinetic energy through the sol shard and fed it back into his cells.
The multiplier ticked upward mid-breath.
He countered with a short, brutal uppercut into the creature's lower jaw. The punch connected with a sound like two tectonic plates colliding.
The kaiju's head snapped back, golden blood spraying in an arc that crystallized instantly on the sand.
It staggered, roaring in fury, then whipped its tail in a horizontal arc faster than any creature its size should move.
Marcus leapt, not flight, just raw leg strength and the tail passed beneath him, carving a trench fifty meters deep.
He landed on the creature's back, feet planting between jagged dorsal plates. The plates flickered with building atomic energy.
It tried to shake him off, thrashing like a bucking continent. Marcus drove both fists downward into the base of its neck controlled strikes, testing density. Scales cracked.
Blue plasma bled from the wounds, hissing where it touched his skin. The radiation tasted different from the others: hotter, older, laced with something almost familiar. Kin.
The kaiju rolled violently, trying to crush him beneath its bulk. Marcus jumped clear at the last second, the creature's side slamming into the ground hard enough to trigger a minor earthquake.
New fissures opened. Blue light leaked upward, Hollow Earth responding to the violence.
Now Marcus took to the air. Not high. Low and fast, circling like a predator.
The creature tracked him with its head, eyes blazing.
It fired its atomic breath for the first time, a sputtering, unstable torrent of blue-white plasma that carved a molten trench across the desert where he had stood seconds earlier.
The beam was powerful, hotter than any variant he had faced, but imprecise. Wild.
Marcus dove through the edge of the beam.
The heat washed over him like a furnace blast. His cells drank it greedily, the sol shard converting the proto-atomic spectrum into fuel.
Pain flared along his left arm where the beam grazed him, raising a shallow burn that sealed before he completed his dive.
He slammed into the creature's chest shoulder-first, driving it backward.
They skidded together for two kilometers, Marcus's feet plowing furrows through the glass.
The kaiju's claws raked his back, deep gouges this time, drawing dark blood that smoked on contact with the air. Real damage.
The first in years.
He felt the dark core stir. The part that liked fighting.
The soldier who had charged bunkers because stillness felt like death.
Marcus grabbed the creature's left arm and twisted, using leverage older than any martial art.
Bone the thickness of skyscrapers cracked audibly.
The kaiju screamed, a sound layered with rage and something almost mournful.
It retaliated by biting down on his shoulder, crystalline teeth sinking through invulnerable flesh for the first time in decades. Blood flowed, his and its mixing.
For seven full minutes they grappled at point-blank range. No powers beyond raw strength and durability.
Fist against scale. Elbow into throat. Knee into ribs. The desert around them became a war zone of new craters and shattered ridges.
Marcus's fatigues hung in tatters. His dark skin was streaked with golden ichor and his own blood.
The kaiju bled from a dozen wounds, its atomic breath firing wildly now, carving random scars across the landscape.
He felt its heartbeat through the contact.. strong, defiant, but tiring.
This one had been protecting something deeper: a clutch of purer eggs, a potential future rival to the true proto-Godzilla he had touched long ago. Territory worth dying for.
Marcus made his decision in the heartbeat between one punch and the next.
He disengaged with a powerful shove that sent the creature staggering. Then he rose into the sky, eyes glowing.
Heat vision lanced out, not the full apocalyptic beam he was capable of, but a precise surgical strike.
Two needles of solar fire struck the base of both dorsal plates, cauterizing nerves and temporarily shutting down the atomic furnace.
The kaiju roared in agony, collapsing to one knee. Blue plasma vented harmlessly from its mouth.
Marcus landed in front of it. The creature lunged one final time, weak, desperate. He caught the jaws in both hands, holding them open, staring into those molten gold eyes from less than a meter away.
Enough, he projected through the faint psychic residue the Venusians had left in him years earlier. Images: the eggs it guarded. The balance. The true king sleeping deeper. *This is not your time to die.
The kaiju thrashed once more, then stilled. Recognition. Exhaustion. Submission.
It had tested the strange solar god that walked its world and found him beyond its strength.
Marcus released the jaws. The creature collapsed onto its side, chest heaving, blood pooling and crystallizing beneath it.
He stood over it for a long time as the yellow sun climbed higher.
His wounds were already closing, the multiplier surging from the absorbed radiation of the fight.
The dark core felt satisfied not bloodlust, but the clean measure of a worthy opponent. The adventurer catalogued every move, every adaptation. The soldier respected the creature's defiance.
Marcus placed one hand on its snout. The scales were hot, alive, ancient. He drew a measured pulse from the sol shard and fed it back into the kaiju, enough to stabilize its furnace, speed healing, but not enough to make it strong enough to challenge again soon.
Then he turned and walked away.
The creature would live. It would return to its eggs. Territory defended, balance preserved.
Marcus had taken nothing from it except the memory of the clash burned into both their cells.
Behind him, the kaiju's breathing steadied. It watched the dark-skinned figure walk across the shattered desert until he vanished over the horizon.
Marcus flew low back toward the pod, the torn fatigues flapping in the wind.
The sol shard glowed brighter than it had in months. The multiplier had climbed again during the fight, another fraction closer to the indeterminate.
Fifty years of such battles had shaped him. This one would be remembered, not as victory or mercy, but as another slow step in the long, dark becoming.
The desert healed around the fallen kaiju. New vents opened. The Hollow Earth breathed on.
And Marcus grew stronger still beneath the indifferent yellow sun....
Marcus then decided explore the sol shard in his chest...
Marcus sat cross-legged on the highest peak of the monument range he had built over the decades, the shattered desert stretching out beneath him like a map of old wars.
The recent kaiju fight still lingered in his muscles, faint bruises along his ribs and shoulder that had already faded to nothing, golden ichor flaking from his dark skin where the creature's blood had dried.
The yellow sun hung low, bloated and indifferent, pouring its radiation into him without pause.
Fifty years of it had turned every sunrise into another quiet accretion of power, but tonight his focus narrowed inward.
To the sol shard.
It rested beneath his sternum, no longer a separate thing but fused.. skin and bone and crystal grown together into a single organ.
A second heartbeat, steady and ancient, syncing now with the distant rumble of the proto-Godzilla far below in the Hollow Earth.
He placed two fingers against his chest and pressed, feeling the faint warmth pulse back.
The shard had changed again after the fight. It drank the kaiju's unstable atomic spectrum greedily, refining it, feeding the multiplier in ways the pod's original core never could.
He closed his eyes and let the memory surface, slow, deliberate, the way he had learned to examine every scar and every adaptation.
The origins of the sol shard went back to the very first months after arrival, before the first major fights, before stasis, before the decades of kaiju blood and crystal isotopes had reshaped everything.
The pod had still been half-buried in the original red dune then.
Marcus had just returned from his first deep exploration of the forming continents, the taste of volcanic ash still on his tongue, the silence of the empty world pressing on him like a weight.
He was fifteen in body, dark-skinned and lean from the old soldier life, but already stronger than any comic-book panel had prepared him for.
The loneliness had carved deep grooves by then, the kind that made a man study something, anything, just to feel control.
He had walked straight into the fabrication bay and spoken to the blue orb.
"Kal. Full power-core schematics. No summaries. Disassembly protocol."
The hologram unfolded in layers of glowing Kryptonian script.. crystal lattices spinning in perfect mathematical poetry.
The core itself was no larger than a human fist back then: black crystal shot through with veins of contained plasma, self-repairing, limitless in theory but throttled by Kryptonian caution.
Jor-El's engineers had built it for a dying world, for a son who would need to survive, not to become something that could break planets for sport.
Safety interlocks everywhere. Quantum resonance dampeners layered like armor. Marcus saw the inefficiency immediately, the over-caution that would limit a god under a young yellow sun.
He spent seventeen hours motionless, tracing every pathway with a finger that never quite touched the projection.
The soldier in him catalogued weak points the way he once cleared a room.
The comic-book kid who had traced Superman panels under bunk light saw the poetry of it: raw solar conversion turned into something portable, personal.
The dark core simply hungered for more.
"Pause," he told Kal. "Backtrack seventeen degrees. Isolate the quantum resonance dampener."
He rebuilt it on the spot.
Raw materials came from the desert itself, iron oxides, silicates, trace actinides leached from volcanic glass the fabricators had harvested while he studied.
He fed them into the bay and let molecular assemblers dance.
The first prototype emerged thumb-sized, black, faintly pulsing. A fragment. Not the full core, never that. A seed.
He crushed it between thumb and forefinger to test.
It held for three seconds, longer than any natural material should, then imploded into a pinpoint of white light. Perfect containment failure. No explosion. Just clean death.
"Too brittle," he muttered.
He rebuilt it seventeen more times over the next three weeks. Each iteration incorporated native isotopes the pod's scanners flagged as unusually stable under high radiation.
He tested tensile strength against his own grip nothing gave.
He tested energy bleed against sustained heat vision at maximum aperture.
The crystal sang, high and pure, then settled into equilibrium.
On the final night, under a sky of wrong stars, he held the finished sol shard in his palm. It was warm. Alive. A portable piece of the ship's heart, modified beyond any Kryptonian safety parameter.
Throughput increased by forty-seven percent. Tertiary interlocks removed.
The dampener array now fed directly into whatever host carried it, turning external radiation into fuel without limiters.
Marcus had stood on the ramp then, the desert wind cool against his skin for the last time before the change.
He pressed the shard against his sternum. Skin parted painlessly, Kryptonian biology already adapting to the idea, bone shifting, muscle making way.
The crystal sank in like it had always belonged there. A second heartbeat clicked into sync with his own.
Pain flared once, bright and clean, then vanished.
The sol shard drank the yellow sun leaking through the atmosphere and flooded his cells with raw, unfiltered power.
The multiplier surged, 2.5 times the strongest Superman analogues became something sharper, faster, personal.
He had felt it immediately: bones densifying, eyes sharpening, the quiet knowledge that he was no longer just carrying the ship's legacy. He had made it his.
Kal's voice had been quiet that night. "An unauthorized modification has been detected in core-adjacent systems."
Marcus had laughed once, hoarse. "Unauthorized by who? Jor-El's ghost? I'm not him."
The orb had pulsed once, slower. "Acknowledged."
That had been the origin. Not an accident. Not a gift from the archives. A deliberate act of a soldier who refused ceilings.
A comic-book kid who had dreamed of gods and decided to build his own engine.
The shard had started as a fragment of the pod's power core, Kryptonian crystal etched with symbols no one on this world would ever read but Marcus had remade it in the first weeks of his exile.
He had studied the technology with the same methodical obsession he once used to strip an M4 blindfolded under fire.
He had removed the safeties because this young Earth had no use for caution.
He had implanted it because carrying it in his hand felt like weakness, and weakness was something the old life had taught him to hate.
Over the fifty years that followed, the shard had become more than a reactor.
It had grown with him.
Every kaiju core he absorbed, those he killed for fuel, fed new spectra into the crystal lattice.
The proto-Shimo's ice had taught it to invert cold. The Venusian disruptors had taught it to turn poison into power.
The blue crystals of the Hollow Earth had opened channels that made the original Kryptonian design look primitive.
The recent fight with the strong Godzilla offshoot had just added another layer: unstable atomic plasma refined into something cleaner, hotter, more efficient.
The shard was no longer black. Faint blue veins now traced through it when he focused, matching the vents below.
It had become a living archive of every spectrum this world could throw at him.
Marcus opened his eyes on the ridge. The sun had set, but its radiation still lingered in the upper atmosphere, feeding him through the shard.
He pressed two fingers to his chest again and felt the pulse, stronger tonight, almost eager.
The origins were simple in the end.
A boy dropped into an empty world with nothing but memories, a pod, and blood that refused limits.
A soldier who studied the only piece of home he had left until he could break it and remake it better.
A shard born from caution turned to hunger, from safety turned to power.
It had started as a fragment of the ship's heart.
It had become his.
Marcus stood. The desert wind carried the distant rumble of another fissure opening far to the north, another precursor stirring, drawn by the radiation he leaked like a walking sun.
He would meet it soon. Test it. Kill or spare according to the balance he had learned to keep.
The sol shard hummed approval beneath his sternum, already calculating the next sunrise, the next fight, the next fraction of growth.
Fifty years ago it had been a prototype.
Now it was simply part of the scale he had become.
He launched into the night sky, slow, deliberate, no sonic boom and let the wind carry him toward the next descent into the Hollow Earth.
There was still more to feed it.
Still more to become.
