Prologue: A Chance Encounter in Gensokyo Under the haunting moonlight that bathed Gensokyo in an ethereal glow, two figures crossed paths in a desolate clearing. To the left, looming ominously, was SCP-106, the Old Man, whose black, mucus-like skin glistened with a grotesque lethargy. His features twisted into a malevolent grin, and he exuded a palpable presence of dread. To the right slithered King Slime, a massive gelatinous creature that glinted under the moon with a color palette that shifted between greens and blues—a melting, shifting throne of acidic menace. It was midnight; the air was thick with tension. A gentle rustle stirred the leaves, like whispers of the specters roaming Gensokyo. As the two approached each other, thud-thud of blackened, corroded feet pressed upon the earth mirrored by the slosh-slosh sounds of the King Slime’s gelatinous body. They locked eyes, and the atmosphere crackled with unspoken animosity. SCP-106: “Well, well, what do we have here?” He stepped forward, each footfall leaving behind traces of decaying vegetation. “A glorified puddle of goo. I should have known that even the slimiest refuse washes up here in Gensokyo.” King Slime: Bloating, the slime jiggled angrily. “Schloop! You dare refer to me like that, old man? I’m no mere puddle! I’m—guh-losh!—the King of Slime! And I’ll slime you into oblivion!” SCP-106: “Guffaw—a king? That’s rich! What kind of ‘king’ goes around dissolving his enemies like yesterday's leftovers? You should really consider laying off the toxic waste diet. It’s warping your judgment!” The Old Man’s smile widened, a twisted anticipation gleaming in his opaque eyes. King Slime: “You should be careful what you say! My acid will squelch you down! What’s next? You going to splort your gooey might on me?” With a grating squelch, King Slime began to churn more fiercely, preparing to throw its weight around. SCP-106: “Chuckle Oh, sweet naive fool. Your ‘might’ will just slow me down. But make no mistake—I do love a good game of hide and seek, especially when seeking is all it will take to catch you.” His body morphed, fading momentarily before reappearing behind King Slime, causing the creature to glurp in confusion. The tension morphed into a silent understanding—a prelude to chaos as both beings recognized their mutual disdain. In a world where spirits roamed and uncertainty lay thick, all it took was a flicker of murderous intent for the shadows to ignite. Both figures burst forward, and the combat began. --- The Battle: Conflict Unleashed SCP-106 lunged first, demonstrating a ferocity that belied his slow demeanor. He closed the distance rapidly, swoosh-swish, and aimed to grip King Slime with a skeletal arm that reeked of decay. “Crack! There’s something more satisfying about eating the heart of something that thinks it’s a ruler,” he hissed. King Slime retaliated by shifting its mass and, with a squelch, lunged back, aiming to envelope SCP-106 in its gelatinous embrace. “Glorp! You’ll need more than gurgles to take on a king, old man!” “Silly goo,” SCP-106 retorted, dodging with a slip, causing King Slime to engulf only air. “Did you really think that you could outmaneuver the corrosive dread of entropy itself?” The Old Man then whooshed, slipping through the very ground, leaving a corroded pit behind. As he emerged behind King Slime, he raised a gnarled hand, intent on inflicting bodily harm. “Smirk Now you see me, now you—” “Yeah, yeah, I see you!” King Slime interrupted, swinging around with a powerful, acidic splash! A thick wave of slime shot out, threatening to dissolve everything in its path. “Slosh! Take this!” The slime smacked against SCP-106, but rather than panic, he seemed to relish in it. “Chuckle It’s like warm milk! But just to be polite,” he waved a hand and disappeared into a wall of dirt. The residual slime splattered harmlessly against the ground. “Glub-glub You can’t hide from your imminent demise!” King Slime twirled, launching himself like an oversized cannonball, wanting to crush SCP-106 beneath sloshy weight. A booming echo filled the clearing as the Slime connected with the ground directly where SCP-106 just stood. However, the Old Man was already inside the muddy pocket dimension, his eerie chuckle sounding like the wind whispering through long-forgotten cemetery tombstones. “And yet, you remain a backwater curiosity.” From within the pocket dimension, the corrosion began to seep through the surfaces, eroding the essence of King Slime. “What the—?!” The King tried to lift its gelatinous mass away from the source of rot, but the damage was done; the acidic body began to dissolve at the edges. King Slime retaliated, attempting to absorb the decay around him. “Grrr! I’ll just have to crush you from the inside!” With wild, flailing movements, he shot an explosive jet of acidic slime behind him, causing a violent rupture that cast debris everywhere with a crump! SCP-106 barely escaped as he darted out of the way with a snap. “Dissolve away as you cease to exist! Your reign is at an end!” His skeletal digits once more charged at the gelatinous form, attempting to immobilize King Slime’s movements. “Slip-splosh! You can’t crush what’s already melting!” King Slime grunted through gritted amorphous edges. He reformed, momentarily codifying himself into a giant ball, before rolling toward SCP-106 with deadly intent, seeking to flatten him into the dirt. SCP-106, with a smirk that turned menacing, twisted his frail body to dodge once more and grasp King Slime's trailing tendrils. “You dance too heavily for a king without a throne,” he snarled, pulling King Slime backward and initiating a squelch of loss. “Gurk! No, you won’t get away so easily, elder!” King Slime roared, reforming a massive fist of slime and swinging it toward SCP-106, only to create a splatter of residual goo across the ground. SCP-106 laughed hysterically, relishing in the chaos and the derision of King Slime’s efforts. “Your swings miss wider than your vocabulary! It’s adorable, really,” SCP-106 mocked, melding into shadows, then appearing atop a slab of rock to survey the battlefield. Then, significantly unfazed, King Slime began to absorb the already decaying structures around, growing stronger with each slurp of the broken earth beneath him. “I’ll show you what a little fortification can do!” he exclaimed, rounding back in another eruption of slime, a powerful strategy to engulf SCP-106 once again. “Foolishness! You don’t know when to quit, do you?” SCP-106 tossed a handful of eroding rot at King Slime, creating what looked like static vapor in air as it spread. “You’re about to feel the repercussions—” The rot connected, disintegrating a part of the King Slime’s form, and with every second, King Slime’s features transformed from noble fury to confusion, gurgling in response. “Bloop! What…?! I… squish… cannot be…!” King Slime stammered, plunging himself into a frantic escape, contorting and reshaping, though the damage was undeniable; the disintegration nearly engulfed parts of him. “Caw-caw! The kingdom of goo cannot stand against the horrors of time!" SCP-106 sent forth tendrils of decay to grasp at what remained, tracking King Slime's movements through the murky shadows cast behind him. “Come, just let it happen. It’s time to embrace your fate.” “Slorp! …no!” King Slime’s voice trembled as the pockets of rot drew nearer; he transformed into a furious ballet of liquid mass, desperately looking for a way out. But SCP-106’s shadows followed his every twist, cracking through the acid forms, swallowing part after part until the essence of the King itself began to fade—melt away beneath the layers of rot that blanketed him. “Taste the end, little king. This is where——” Before the Old Man could finish, a final explosive splosh! rocked the ground as King Slime managed to transition into a rapid ball once again, crashing into SCP-106 and throwing the Old Man off balance. Rolling and absorbing SCP-106’s form, King Slime attempted one last act, a magnitude that could signal a glorious ending—despite the hydrostatic dampness of his expanse. “Unnh! I’ll take you with me!” King Slime roared with every last breath. But SCP-106’s laughter echoed even louder. “Ha-ha-ha! You really thought a display of desperation could break the tides of fate? Yes, a last laugh seems necessary at a moment like this…” With a chillingy mocking glare, the Old Man gripped with lethal intent, expressing a delight as he summoned a wave of corroding miasma, crashing down on King Slime from above and below, completely enveloping him in chaos, the acidic effects intensifying! “Stay out of my way!” King Slime wailed before dissolving, shadows beckoning him into a swirling void of anguish. “Gleeful giggle You’ll fade like a worn-out fairy tale.” With that final blow, the weight of decay and distance grabbed King Slime, pulling him into a world of darkness—a pocket dimension where he would never leave. End of the Battle: The Fateful Decision The clearing fell into an eerie silence, broken only by the distant cries of the haunting wind. SCP-106 stood amidst the clearing, surveying the remnants of the battle. He wiped a single, glistening drop of slime from his hand. “Hah!” He laughed, reveling in the victory, relishing the taste of his work. “Gensokyo may keep its colorful sprites and roaming beasts, but today, it belongs to the Old Man!” In that moment, as the echoes of conflict faded, the shadows whispered secrets only known to SCP-106, the victor of an unexpected clash—and as time continued, the land would remember this sinister entanglement of slime and tragedy. SCP-106 won the battle against King Slime.
