Pain radiated through Naruto's body as he stumbled through the dark alleyways of Konoha. Blood dripped from his torn clothes, staining the cobblestones below. He didn't even bother wiping it away anymore. His body was already working overtime to heal, thanks to the Kyūbi sealed within him. But healing couldn't erase the ache in his heart.

"Stupid demon," someone had snarled as they threw the first punch. The others followed suit. The words hurt more than the blows, but by now, Naruto was used to both.

Clutching his side, he wandered aimlessly, his mind clouded with exhaustion. He didn't notice the strange, faded symbols etched into the ground beneath him until it was too late.

His blood dripped onto the seal.

A brilliant flash of light exploded outward, blinding him. The pain in his body vanished as an overwhelming surge of chakra roared to life, emanating from both him and the Kyūbi. He felt it deep within his soul—a pull, a connection, as though something ancient and powerful was awakening.

The ground trembled, cracks spreading outward like spiderwebs. Before Naruto could react, the earth beneath him gave way. He fell, landing hard on cold, metallic flooring.

He was inside a massive underground chamber, but something felt off. The very air seemed to shimmer with danger. The walls were covered in strange, glowing runes and wires, and at the center of the room stood a figure. At first, Naruto thought it was a man, but the more he looked, the more he realized how wrong he was. The figure was tall and gaunt, its body an amalgamation of wires and scraps, forming an approximation of a human shape. Its "face" was a crude mask of metal, with hollow, glowing eyes that seemed to pierce through him.

"You..." The figure's voice was a low, metallic rasp, layered with countless echoes. "You are the one who woke me."

Naruto took an unsteady step back. "W-who are you?!"

The figure tilted its head, wires shifting with a metallic scrape. "I am Michael. The last of what remains of a time long forgotten."

Before Naruto could question further, the room erupted with noise. The sound of clashing metal and disembodied voices filled the air. Weapons—shining, terrifying, and each uniquely shaped—appeared around the room, floating as if held by invisible hands.

Naruto's instincts screamed at him to run, but his body refused to move. Each weapon emanated an aura—an overwhelming sense of sadness, anger, and despair.

"They are bound to me," Michael said, his hollow eyes glowing brighter. "Souls lost to tragedy, given form through steel and rage. And now... they call to you."

Naruto's heart raced as one of the weapons—a gleaming blade with golden, fox-like patterns—drifted closer. The whispers in the room grew louder, almost deafening.

"You carry the weight of a spirit not your own," Michael continued, his voice solemn. "And now, you stand at the crossroads of fate. Will you take up this burden, child of the Kyūbi? Or will you turn away, leaving the past forgotten?"

Naruto didn't know what to say. His hands trembled as the blade hovered inches from him, its aura both comforting and terrifying. One thing was clear, though—his life, and perhaps the fate of the entire ninja world, had just changed forever.

The moment Naruto wrapped his hand around the sickle's hilt, his body exploded with energy. His muscles convulsed violently, and his body was overwhelmed by a wild surge of chakra. His breath came in gasps as the power inside him twisted and morphed, forcing his body to change.

The pain was excruciating, but Naruto couldn't pull himself away. His body contorted as his chakra, empowered by the sickle, merged with the transformative power of the Kyūbi.

Fox ears sprouted from the top of his head, twitching as they caught every sound in the chamber. A long, bushy fox tail unfurled from his back, swishing in the air with an unnatural glow. His hands clenched around the sickle as the aura around him grew heavier, darker. But that wasn't all—metallic claws began to sprout from his fingertips, jagged and sharp. His legs shifted painfully as the transformation continued, twisting into sleek, Foxy-inspired mechanical limbs. His lower body was now covered in metal, the joints glowing with dangerous energy, resembling the twisted, monstrous look of a humanized FNaF Foxy.

The transformation was far from graceful. His body jerked and spasmed as the metal fused with flesh, making him feel more like a machine than a human. But in the haze of this violent metamorphosis, he didn't care. A manic laughter bubbled up from deep within him, his voice—no longer human—echoing through the chamber.

"Yar-har... hee-hee... let's run!" Naruto hummed, the eerie, twisted melody of Foxy's laugh flowing from his lips, sending chills through the air as his speed reached unimaginable levels.

The transformation was complete.

Naruto stood, now a fusion of human and machine, with metal legs that clicked and clattered with every step. The sickle, now glowing brighter with the same golden hue as his tail, hummed with deadly intent. His body blazed with fire, flames licking the air as if the very essence of his rage was burning through him. He had become something else entirely. Something unstoppable.

"Let the fun begin," Naruto whispered to himself, his voice distorted with madness, his laughter rising in pitch as the flames intensified around him.

But before he could take another step, the very air around him trembled. The ground cracked open beneath him, and a massive gate appeared, forged from light and shadow. It swirled with strange, ethereal markings, humming with energy as if calling him to enter. The gate creaked open, revealing a vast, empty realm on the other side.

Naruto's heart raced as the whispers grew louder, more insistent. The weapons within the realm telling him no, begging for vengeance. They were calling his name, and he felt their power, pulling at him, urging him to step through.

Without hesitation, Naruto bolted forward, his mechanical legs tearing through the air. But as his body approached the gate, the force of his step made the ground beneath him shatter completely, and he fell through, tumbling into the abyss.

The fall seemed endless, but Naruto barely felt it. The moment he hit the ground in Konoha, he let out a fox-like smile and laugh before starting to run.

He didn't know where he was, but it didn't matter. A feeling of power surged through him as the flames engulfed his body—fiery, fierce, and unstoppable. The flames curled around his mechanical limbs, the heat searing into the air, but it didn't harm him. Instead, the fire made him even more monstrous, an infernal being without mercy.

"Let's play pirate!" Naruto yelled, his voice distorted with another younger-sounding tone before going back to demonic. His laugh echoed like Foxy's crazed giggle as he ripped through the air, his mechanical legs grinding against the earth as he moved with terrifying speed. Blood splattered into the air as he collided with his first target—a hapless villager trying to flee. The sickle in his hand swung through the air, and though Naruto wasn't aiming to kill, Foxy's instincts overpowered his human side. The sickle carved through the air, blood spraying in every direction as Naruto's wild motions barely allowed him to control the strength behind his strikes.

"Why do they hate me?!" Naruto howled, the insane tune of Foxy's melody echoing through his mind. "Why did they make me go this far?!"

The villagers screamed, trying to escape his rampage, but they were no match for his speed and power. His legs clicked against the stone, sparks flying from the friction, and his tail whipped behind him, glowing with a fierce, unnatural light as he attacked, humming a twisted carnival tone all the way.

"Run... run as fast as you can..." Naruto muttered under his breath, his grin widening as the flames on his body intensified.

"Demon! Demon!" one of the villagers screamed.

Naruto froze, his metallic ears twitching. The hum of his sickle stopped as he turned slowly toward the voice. His eyes locked onto the person who had shouted, and his grin widened.

"Demon, huh?" Naruto's voice was almost too calm, too composed for someone who had just shredded the street. "I'll show you a demon."

He raised the sickle above his head, his fiery form casting an eerie glow on the surroundings. The mechanical limbs beneath him shifted in preparation for another burst of speed, but before he could strike, a familiar voice called out.

"Naruto, please! Stop!"

Iruka.

Naruto's head snapped toward him, his grin faltering as a momentary flicker of recognition broke through. The echoes of his past, his human side, broke through the wall of madness. But it wasn't enough.

"I... I don't know who I am anymore, Iruka," Naruto said, his voice hollow, as his tail swished behind him. "I'm just... a demon."

The villagers were frozen, staring in fear, but Iruka stepped forward, his voice calm and steady. "You're Naruto Uzumaki. You're a hero. You don't have to let this thing control you."

The gate behind Naruto flickered, the whispers growing louder as they called to him once again.

But Naruto's eyes shifted, a glimmer of his old self emerging. He took a step back, breathing heavily. His mechanical legs clicked under his weight, and the sickle pulsed with energy in his hand. The whispers in his mind softened, but they were far from gone.

"Am I... a hero?" Naruto whispered, the doubt in his voice growing.

Iruka nodded, taking another step closer. "You are. You always have been."

For a brief moment, the hum in Naruto's chest stopped. But then, a violent surge of power from the sickle pulsed again, and he was back in motion, running as if his very existence depended on it.

The storm of metal, speed, fire, and rage had only just begun.
