monster verse:Gene Evolution

Alex moved through the tunnel with his wings folded tightly, body tensed as he ascended through the narrow shaft. Gravity aided his climb—at first. But then came the shift.

That familiar crushing sensation hit him again, only this time it was worse.

Much worse.

His massive frame, now bulked up after months of evolution and growth, strained against the narrow tunnel. Gravity didn't just pull at him—it crushed him. Last time, his bones had cracked under the pressure. This time, they were breaking.

His vision blurred as pain exploded across his body. Ribs snapped. Joints dislocated. Wings scraped violently against the jagged stone. He fought to stay conscious, knowing that blacking out now meant plummeting back into Hollow Earth—probably for good.

"Not now… not after coming this far," Alex growled in his mind.

Every flap of his wings caused them to grind against the stone walls, shedding scale and skin. He could hear the scraping echo, feel the agony with every motion—but he had no choice. Inch by inch, he forced his way upward.

Then, finally—

Light.

He emerged from the tunnel like a battered missile, crashing into the cave chamber at the top, gasping for air. His wings hung limp at his sides, bones twisted and bleeding from the raw wounds he'd sustained on the ascent.

He collapsed just past the mouth of the tunnel, his breaths ragged, chest heaving. He dragged himself out into the open, the smell of Skull Island's air finally hitting his nostrils again.

He was back.

Alex didn't move for a while. His regeneration kicked in, slowly mending shattered bones and torn muscle. He waited, silently enduring as his body pieced itself back together.

Then, once he could stand again, he turned around and looked at the tunnel.

No more surprises.

With a snarl, he smashed his entire body against the cave wall, his weight and force combining into a violent quake. The already-damaged ceiling collapsed, rocks tumbling down as the entrance caved in completely.

Dust rose. The tunnel was sealed.

No one else was getting out the way he did.

Alex exhaled heavily.

He'd survived Hollow Earth.

Now, it was time to prepare—for what comes next.

He soared above Skull Island's vast wilderness, wings stretched wide across the sky. His body cast a massive shadow over the jungle below, and every beat of his wings caused gusts that sent trees swaying violently.

He was heavier now—bulkier, denser, and not in a good way.

Despite reaching the Upper Apex Tier, he hadn't evolved any further. His body had simply stockpiled mass like a bear preparing for winter. And it showed. Every wingbeat drained him faster than before. His stamina was shorter, his climbs slower, and gliding had become more of a necessity than a tactic.

He was, for lack of a better word—chubby.

Not weak. Just… grounded. Flight was becoming less of a weapon and more of a burden.

Still, as he cleared the last ridge of Skull Island, Alex threw back his head and let loose a powerful roar. The sound rippled through the clouds, announcing his departure to the island and every monster on it.

But in his mind, the words were clearer:

"I'm back, b*tches."

He was tired. Not just physically—emotionally. Hollow Earth had been a warzone. Skull Island had been a meat grinder. It was time to leave both behind.

He'd thought about going to Borneo again. That place still lingered in his memory—his starting point in this monstrous world. But that plan could wait.

He had spent too much time on hollow Earth the time was still ticking for him.

Isla Nublar was calling.

It was his territory now. His turf. His resting place.

. He couldn't afford to stall any longer. The evolution to Titan Tier wasn't going to wait forever.

With a slow, labored twist of his body, Alex angled toward the open ocean, wings flaring.

He wasn't fast anymore. He wasn't light.

But he was still dangerous—and still growing.

Meanwhile – MONARCH HQ

"Black Wyvern has been detected leaving Skull Island airspace," a female technician reported, eyes locked on the monitor displaying a pulsing red dot moving across the ocean.

Dr. Serizawa and Houston Brooks stood over her, silent.

"He's been gone for months," Brooks muttered. "We thought we'd lost him."

"We didn't lose him," Serizawa said, arms crossed. "He simply went somewhere we couldn't follow."

The technician adjusted her screen. "There's something else. His mass signature has changed."

"Changed how?" Brooks asked.

"He's… bigger. A lot bigger. But not faster. It's affecting his movement rate. And—" she paused, typing quickly— "We're detecting elevated traces of radiation. Not at titan levels, but definitely higher than before."

Brooks frowned. "He's bulking up. Preparing."

"Or storing energy," Serizawa replied. "He's on the path. The question is what happens when he reaches the end of it."

"If he's really going to evoy into a Titan, he's going to need a lot more radiation," Brooks added. "And if he starts seeking it out like the MUTOs…"

"Let's not assume the worst," Serizawa said quietly, eyes narrowing. "Let's watch for now it's too early to judge ".

Back to Alex

Salt winds lashed against his scales as Alex flew over the open ocean. His wings ached. His joints burned. He'd never had to rest during long flights before.

But now?

Every beat of his wings felt like dragging the weight of a mountain. Even gliding took effort—his swollen, heavy frame wasn't built for speed anymore. He hated it. Hated being weighed down. Hated feeling sluggish.but later it would be worth it.

He needed to rest in the sea a few times for breaks. Something he had never done before.

A day and six hours after leaving Skull Island, Alex finally arrived at Isla Nublar—his home, his territory, and the one place he felt secure.

Despite the exhaustion pulling at his wings and bones, a faint flicker of relief sparked within him as he glided over the familiar island. Below, life bustled as it always had. Herds of herbivores moved across the plains. Packs of predators prowled the forests. The island was still wild… still alive.

Except for one new issue.

Smoke curled from the volcano, thin but persistent—a warning. It wasn't erupting, not yet, but it was very much awake. Alex eyed it warily. It wasn't his problem now, but it might be one later.

He turned his attention back to his old resting place.

The avian dome—his makeshift den—was gone.

In its place stood a new structure: larger, broader, covered in hexagonal panels that shimmered faintly. It still resembled a dome, but it was clearly reinforced and advanced. Monarch's handiwork.

Alex narrowed his eyes slightly, noticing drones circling above him, their silent propellers buzzing like insects. On the cliffs nearby, Monarch scientists observed him, no doubt logging his return and condition.

He pretended not to see them.

'Seems Monarch's been busy,' he mused, noting how closely they were monitoring him.

But frankly, he couldn't care less right now.

He dragged his heavy body inside the new structure, ignoring the soft hum of scanning equipment embedded in the walls. The floor was cool and wide. Spacious enough for his bulk.

He coiled his long, massive tail around his body, his wings folding tight against his sides.

He was tired.

Not just physically, but mentally.

He needed rest.

So, with one last glance at the volcano's smoke drifting into the sky, Alex closed his eyes, and let the weight of the world fade into silence.

Monarch Outpost — Isla Nublar Observation Station

Within the command room lined with screens and glowing data displays, Dr. Serizawa, Dr. Houston Brooks, and Dr. Ilene Chen stood quietly as the live biological readout of the Black Wyvern—Alex—flickered across the monitors.

Now that he had settled inside the dome constructed specifically for him, Monarch's internal scanners were finally able to perform a full bio-sweep of the creature's physiology in real time.

What they found sent a ripple of stunned silence through the room.

"He's developed venom glands," Dr. Chen said first, adjusting her glasses. "And not just simple toxin sacs… These are complex venom ducts, connected directly to modified grooves in his fangs. Similar in function to those of front-fanged vipers."

"That's not all," Serizawa said, eyes narrowing at another part of the scan. "Look at the neural tissue along the spine. It's embedded with... electrogenic cells. Like those in electric eels, but exponentially more concentrated."

"Electric eels?" Brooks echoed, leaning closer. "How is that even possible? You're telling me this thing somehow evolved bioelectric capability and venom delivery systems within a matter of months?"

"It shouldn't be possible," Dr. Chen admitted. "No natural evolutionary timeline explains this. And electric eels and snakes are far too small to have influenced a creature of this scale through simple consumption. This isn't just assimilation—this is targeted adaptation."

Serizawa nodded slowly, the implications beginning to settle like a weight on his shoulders. "He didn't just acquire traits. He incorporated entire biological structures.we knew that it could do this since we had seen it in action at San Francisco,but how many genetics can it Intergrate before collapsing?".

Brooks looked at the hovering 3D model of Alex, now highlighted in areas of glowing blue (bioelectric fields), green (venom ducts), and a faint reddish hue around the muscles indicating new growth rates.

"since we know that it can assimilate genetics, what's concerning is where it got those gave it the new upgrades Brooks said.

Dr. Chen turned from the screen. "We'll need to update the Monarch files. His biological classification isn't even valid anymore. The 'Black Wyvern' entry has to reflect this… rapid metamorphosis."

"And we still have no idea where it ends," Serizawa added darkly.

Silence fell again as the system continued processing Alex's data.

And deep within the dome, unaware of—or perhaps uncaring about—their observations, Alex slept soundly, curled within himself like a cat.

End of chapter.
