The air in the derelict industrial district on the edge of town was thick with a damp, cloying fog that tasted of rust and old soot. Springtrap moved through the shadows with a heavy, rhythmic clanking, his every step a symphony of groaning metal and snapping mechanical parts. Inside the rotting, moss-stained animatronic husk, what remained of William Afton was a focused, cold intelligence, his white, pupilless eyes scanning the gloom for any sign of a fresh soul to torment. He was preoccupied, his mind racing through calculations of remnant and the structural integrity of his decaying cage, when he rounded the corner of a crumbling brick warehouse and collided—hard—with a figure emerging from the mist.

The impact sent a jarring shudder through William's mummified frame. The other person stumbled back, a sharp, manic laugh cutting through the silence. "Hey! Watch where you're going, you oversized pile of scrap!" William steadied himself, the springlocks in his knees hissing as he straightened. Standing before him was a young man with skin as pale as bone, his eyes wide and unblinking, rimmed with charred lids. A permanent, jagged grin was carved into his cheeks, stretching from ear to ear in a grotesque, bloody mask.

It was Jeff the Killer, his white hoodie stained with fresh crimson, a kitchen knife glinting in the pale moonlight. William didn't flinch. He looked down at the "boy" with a sense of clinical detachment, his distorted, mechanical voice rasped out from behind the Spring Bonnie mask. "You are a noisy creature, aren't you? A mere child playing with a kitchen utensil." Jeff’s grin seemed to widen, his grip tightening on his blade. "A child? I’ll show you—" Before Jeff could lung, a heavy, oppressive silence fell over the alleyway. From the deeper shadows behind Jeff, a massive, silent shape materialized.

Michael Myers stood there, his featureless white mask a void of emotion, his breathing a steady, rhythmic rasp that matched the cold efficiency of his stance. Beside him, the air seemed to warp as a tall, faceless entity in a dark suit—the Slender Man—loomed over the scene, his static-filled presence causing William’s internal sensors to scream in protest. Across the way, leaning against a rusted dumpster, a man in a tattered hockey mask—Jason Voorhees—watched the exchange with a gripped machete, his presence like a mountain of immovable, vengeful meat.

William Afton surveyed the gathering. For the first time in thirty years, he felt a flicker of something that wasn't just malice—it was a dark, twisted curiosity. He wasn't the only monster in the world, it seemed. He was simply the most sophisticated one. He took a step forward, the metal of his feet crunching on the gravel, his voice a low, vibrating growl that carried the weight of his decades of suffering and slaughter. "I see the shadows are crowded tonight," William rasped, his eyes flaring with a malicious light as he addressed the assembly of nightmares. "Tell me, children... do you know what it truly means to endure? To be broken, fused with your sins, and yet always come back? I am William Afton, and I have forgotten more about the art of the kill than all of you combined. Now, move aside, or I shall see if your 'immortality' can withstand the pressure of a springlock failure."
