OVERHAUL'S NIGTHMARE

Down below, the air was thick with dust, smoke, and screams.

Four Arms stood amidst wreckage. Crushed walls, split pipes, unconscious thugs scattered like leaves in a storm. His crimson skin was coated in grime and blood—not his own. His four fists dripped with fury.

Kendo Rappa was the first to charge. "YOU WANNA THROW HANDS?! THEN BRING IT!!"

Four Arms caught both of Rappa's fists—then slammed his knee into the brawler's gut, lifting him off his feet before bringing all four fists down on his back, driving him through the floor like a meteor strike.

Soramitsu Tabe lunged from the side, teeth gnashing. "I'll eat you al—"

CRACK.

A single elbow to the jaw sent Tabe flying across the room, crashing into support beams and collapsing in a heap, twitching.

Yu Hojo's crystals burst from the ground, sharp and deadly. Four Arms didn't slow down—he charged straight through them, fists spinning in a windmill motion that shattered every spear.

"You think you can take a child," he snarled, grabbing Hojo by the throat. "And just walk away?!"

He hurled him into a wall. The impact broke concrete.

Deidoro Sakaki tried to sneak up, laughter echoing drunkenly.

Too slow.

Four Arms turned and grabbed his face—slammed him into the floor once, twice, three times—then flung his limp body into a metal door.

Nemoto tried to speak—his voice quirk attempting to force compliance.

"I don't care what your voice says."

Crunch. A headbutt. Then a fist to the ribs that snapped him into unconsciousness.

One by one, the Eight Precepts of Death were dismantled. Brutally. Efficiently. And yet—each strike carried purpose, anger not just at the crime, but the trauma they had inflicted on that little girl.

Then—a hum. A low click-click-click echoed through the devastated corridor, heels hitting the broken tile floor with unnerving calm. Kai Chisaki—Overhaul—stepped into the chamber.

The scent of blood and dust hung heavy in the air.

His eyes scanned the room. Bodies of his lieutenants were sprawled across the rubble. Yu Hojo, unconscious. Rappa, twitching. Nemoto, bleeding from his nose. The reinforced wall where Eri's containment cell once stood… destroyed. Chains shattered. The bed overturned.

She was gone.

For a heartbeat, Overhaul stood in silence.

Then his hand twitched.

Veins pulsed across the back of his palm as his rage flared like venom. He looked up—and saw Four Arms standing amidst the wreckage. His massive frame loomed like a titan. Each of his four fists were bloodied and clenched.

"You…" Overhaul hissed. His voice was tight, shaking. "What did you do?"

Four Arms turned slowly, looming over him. "I saved her."

"You…" Overhaul took a step forward, his eyes wide with fury, voice cracking. "You touched her. You ruined everything! She's not yours!"

The ground under his feet began to twist. He slammed his bare palm into the concrete—and the entire floor exploded.

The floor detonated beneath Four Arms, erupting in a violent storm of stone and steel. Jagged spikes shot up from the ground, twisted girders hurled like javelins, and massive concrete slabs tore free from the structure like an enraged beast lashing out. The explosion launched the crimson titan backward through a metal beam, shattering it on impact as he skidded across the fractured ground.

Overhaul stood amidst the chaos like a conductor of destruction, one hand pressed to the floor, the other trembling from strain. His mask was cracked, eyes wild, veins bulging.

"You shouldn't have come here!" he bellowed. "You don't understand what I'm doing! You're ruining everything!"

Four Arms rose, chest heaving, blood dripping from a cut above his brow. He rolled his shoulders, ignoring the sting. "No. I understand exactly. You're a coward hiding behind borrowed power and a little girl's blood."

With a roar, Overhaul slammed both hands down.

The hallway exploded again—columns bursting, floor rising like ocean waves, walls splitting to unleash a torrent of sharp rock. Overhaul surfed the chaos on a rising platform of rubble, launching debris like bullets, forcing Four Arms into a defensive dance.

A slab came from the side—Four Arms crushed it with a backhand.

A spike shot from beneath—he leapt, spun mid-air, and landed with a quake that cracked the ground.

But he was slowing.

Overhaul was reshaping the battlefield faster than he could close the distance, and every second allowed the villain more control.

"You think strength alone will save her?" Overhaul snarled, voice dripping with madness. "You think brute force will undo my design?! I'll tear you apart and build something better from your corpse!"

He thrust a hand toward the mangled bodies of his lieutenants. Rappa. Tabe. Flesh and bone rippled like water as they were sucked toward him.

"No," Four Arms growled, charging forward—too late.

The fusion was grotesque. Overhaul's body pulsed and expanded as he absorbed them—muscles twisting, extra limbs sprouting, skin hardening into bone-like plating. A crown of jagged horns crowned his mutated head, and from his back erupted twin tails formed from spinal columns and gnarled flesh.

The monstrosity screamed, voice echoing with three souls in conflict.

"You're nothing now," it said, stepping forward. Each footstep cracked the floor. "I've become evolution itself!"

It lunged—and Four Arms met it head-on.

Fist collided with clawed hand. Another arm grabbed Four Arms by the throat and slammed him into the floor. A second punch smashed into his ribs, another struck his knee. The beast lifted him and hurled him like a missile through a reinforced wall.

Four Arms rolled once—twice—then caught himself, panting.

"You're fast," he muttered, spitting blood. "But you're still a coward."

The monster snarled and charged again. Four Arms ducked, caught two arms, blocked a third—but the fourth slammed into his side. He twisted with it, using the momentum to throw the beast off balance and retaliated with a brutal hook to its jaw, sending teeth and spittle flying.

He followed it—left, right, left, uppercut—every fist a cannon.

The monster staggered, then retaliated, using its tails like whips—one wrapped around Four Arms' arm, the other lashed his chest, drawing blood. The creature reeled him in—and Four Arms let it.

He launched a headbutt that shattered the monster's nose, broke the tail's grip with raw strength, then lifted the beast overhead with two hands and powerbombed it into the ground so hard the floor beneath them collapsed into the next level.

Dust and silence filled the air.

Then, a growl.

The creature rose, bloodied but laughing, its voice a chorus of agony and defiance. "You can't kill me. I am the future. I'll rebuild this world from your ashes!"

Four Arms looked down at the shaking form and rolled his neck.

"Then let's tear down your future."

He leapt, all four fists glowing with kinetic fury. Time seemed to slow.

The first punch snapped a rib.

The second shattered the fused armor.

The third caved in the creature's shoulder.

The fourth—

Was the hammer that ended it.

The monster collapsed, limbs twitching, body breaking apart under its own weight.

Silence reigned.

Then, Four Arms slowly stepped back. His hands trembled—not from pain, but rage held in check.

He turned back to his human form and raised his Omni-Dex and commanded," Scan DNA."

Omni-Dex released a green light and beeped," DNA SCAN: SUCCESSFUL."

Then he turned his Omnitrix and commanded," REWRITE THE DNA TO PURE HUMAN."

Omnitrix released its icon green flash and turned Overhaul into a quirkless person. A fitting end for someone like him.

Synapse-Grade came near him and turned into Echo Echo, similar Four arms also turned into Echo Echo and merged together.

Hearing distant sounds of police sirens and imminent arrival of heroes, Echo Echo turned into XLR8 and disappear with flash of white and black.
