The train screamed forward through the burning city, sparks raining from the rails like falling stars.
Nobita stood at the center of the roof, chest heaving, Hunter Mode still active.
His pupils were razor-thin.
Every sound was sharp.
Every movement screamed danger.
Across from him, Simmons staggered.
No longer the panther.
Human again.
Bare skin covered in blood and burns, knees shaking, eyes wide with disbelief.
"You…" Simmons coughed, wiping blood from his mouth.
"You're not human anymore."
Nobita didn't answer.
He stepped forward.
And punched.
Simmons' head snapped sideways.
Another punch.
And another.
Leon shouted from behind, "NOBITA—STOP—!"
Nobita didn't hear him.
All he saw was every death Simmons caused.
Every scream.
Every city burning.
His fists came down again and again.
"You think you're a god?!" Nobita roared, slamming Simmons into the train roof.
"You think the world belongs to you?!"
CRACK.
CRACK.
CRACK.
Metal bent beneath Simmons' body.
Helena whispered, shaken, "He's… losing himself…"
Simmons laughed through broken teeth.
"Yes… yes… keep hitting me…"
His body twitched.
Nobita froze.
A sharp pain stabbed through his chest.
His vision flickered.
The system blinked violently.
---
[WARNING]
Hunter Mode — BIOMASS CRITICAL
Energy Reserves — DEPLETED
Forced Deactivation in: 10… 9…
---
Nobita staggered back.
"…What?"
His breathing turned ragged.
Strength drained from his limbs like water leaking from broken glass.
Simmons' laughter grew louder.
His body erupted again.
Bones burst outward.
Flesh piled and twisted.
A grotesque, hulking mutation—bigger than before—rose screaming into the night.
Leon raised his gun. "DAMN IT—!"
The monster slammed its fist down—
BOOOOM!
The roof caved in.
Nobita was crushed into the metal, the air ripped from his lungs.
Hunter Mode died.
---
[HUNTER MODE — DISABLED]
User Fatigue — EXTREME
---
Simmons loomed over him, drool and blood dripping from massive jaws.
"…I'll eat you," it growled.
"Absorb you.
And take that regeneration for myself."
It opened its mouth wide.
Leon fired nonstop.
"GET AWAY FROM HIM!"
Bullets tore into Simmons' side.
Gian roared beside Doraemon, firing dual air cannons.
"LET GO OF NOBITA—!"
Simmons snarled and backhanded Leon—
The impact sent Leon flying off the train—
CRASH—
He slammed onto the roof of an oncoming train on the opposite track.
"LEON!" Helena screamed.
Simmons turned, eyes locked on fresh prey.
"…Two hunters," it growled. "Even better."
It leapt toward Leon.
Shizuka cried out as helicopter gunfire intensified.
"I CAN'T HOLD MUCH LONGER!"
The barrier cloth shimmered violently.
A bullet punched through—
Shizuka screamed as it tore into her shoulder.
"SHIZUKA!" Suneo shouted.
Doraemon's voice cracked. "NO—!"
Blood stained her sleeve—but she didn't drop the barrier.
"I'm… okay…!" she gasped.
"JUST—FINISH THIS!"
Nobita saw everything.
Leon falling.
Shizuka bleeding.
Everyone breaking.
Something snapped.
He forced himself upright.
His body screamed in protest.
"…I'm not done," he whispered.
His eyes burned—not blue—
—but black.
"Commander Touch."
The air collapsed inward.
High above, the helicopter suddenly froze.
The pilots screamed.
"What—?! Controls aren't responding!"
The machine lifted—violently—like it had been grabbed by an invisible god.
Nobita raised his trembling hand.
"…Get away from them."
With a roar, he hurled the helicopter.
It smashed into Simmons mid-leap—
BOOOOOOM!
Fire and metal exploded across the tracks.
Simmons was sent crashing back onto the train roof.
Nobita didn't stop.
He turned—hand shaking—and clenched his fist again.
"Come back," he whispered.
Leon's body lifted from the opposite train, suspended in midair.
Leon shouted, "NOBITA—PUT ME DOWN—!"
Nobita dragged him through the air and slammed him safely onto the roof beside Helena.
The pressure vanished.
Nobita collapsed to one knee, coughing blood.
"…Vent… now…!" he gasped.
Helena grabbed Leon.
Doraemon scooped Shizuka up.
They smashed open a vent hatch and dropped into the train car below.
The roof above them exploded.
Simmons rose from the fire.
Burned.
Mutilated.
Still laughing.
"…Good," the monster rasped.
"…Run."
Inside the train, alarms blared.
Lights flickered.
Nobita leaned against the wall, barely standing.
The train never slowed.
Metal screamed against rails as it tore through Tokyo's burning arteries, sparks spraying like rain beneath the night sky. Inside the tunnel of wind and fire, Simmons' mutated body twisted unnaturally—his back riddled with bullets Leon and Helena had already poured into him.
Dozens of rounds.
Still standing.
Still breathing.
The bullets embedded in Simmons' back began to glow.
Leon noticed first.
"…That's not normal."
The flesh around the bullets pulsed, veins bulging grotesquely.
Then—
FWOOOOM.
Every embedded round was ejected at once, flaring outward like shrapnel from a living cannon.
Leon and Helena dove as metal tore past them, ripping chunks from the train roof.
"He fired them back—?!" Helena shouted.
Simmons snarled, muscles ripping as he twisted and leapt onto the opposite track, landing on the oncoming train with a deafening crash.
The mutated form sprinted against traffic, claws digging into steel, sparks trailing behind him like a comet.
Inside the train car below, Doraemon forced Shizuka down onto a seat.
"Stay still—please—!"
Her shoulder bled heavily, but she clenched her teeth.
"I can still fight," she whispered.
"No," Doraemon said firmly, wrapping bandages with shaking paws.
"You already did."
Above them—
Gian and suneo fighting Simmons with his doraemon gadget
Dekisuki stared at his weakness detector magnifying glass that he got from doraemon earlier, eyes wide.
"…Wait."
The screen flickered, isolating Simmons' heat signature.
"That shape… that mutation—"
He zoomed in.
"There's a secondary face," Dekisuki said urgently.
"On his torso—centaur-like structure. That's the control core. If we damage it—"
Leon fired across the tracks.
The shot grazed the target—but Simmons barely reacted.
"Damn it!" Leon growled. "Too unstable—he won't stay still!"
Simmons turned.
And smiled.
Not with one face—
But two.
"Nobita," the monster roared, voice echoing across both trains.
"COME OUT."
Then—
He charged.
Like a bull.
He smashed into the opposite train—
BOOOOOOM!!
The train flies
Metal screamed as entire carriages derailed, sparks exploding into the air.
Nobita already knew what will going to happen now.
He climbed back up through the hatch again.
Wind slammed into him.
The roar of steel drowned out everything else.
He stood on the roof again.
He drew lightning hawk from belt that he got from leon earlier.
Leon shouted, "Nobita—he's baiting you!"
"I know," Nobita said calmly.
Simmons leapt.
Straight toward nobita train.
Time slowed.
The wind faded.
The firelight dimmed.
Nobita's breathing steadied.
Hunter Mode was gone.
No enhancements.
No system warnings.
Just him.
Dekisuki screamed, "THE FACE—AIM FOR THE FACE—!"
Nobita raised the Lightning Hawk.
One hand.
Perfect posture.
Perfect alignment.
Simmons' monstrous leg lifted—
Nobita fired.
BOOOOOOM.
The shot tore straight through the centaur-face, detonating flesh and bone in a brutal explosion.
Simmons screamed—not in rage—
—but in pain.
His leap faltered.
His balance shattered.
Nobita didn't hesitate.
He fired again—
This time at the leg.
CRACK.
The limb snapped sideways.
Out of control.
Simmons smashed into the oncoming train—
BOOOOOOOOOOM!!
The impact was catastrophic.
Metal folded.
Fire erupted.
The monster was thrown skyward—
—and landed back onto the roof of Nobita's train with a deafening crash.
Smoke cleared.
Simmons lay there.
Human again.
Unconscious.
Broken.
Silence followed.
Leon slowly lowered his gun.
"…That shot," he said quietly.
"That wasn't luck."
Helena looked at Nobita, breathless.
"You ended it."
Nobita stared at Simmons' motionless body.
"…Not yet," he said.
The train continued forward.
Still moving.
Still alive.
But unconscious...
To be continued...
