Act I: The Summoning

The theater was vast, velvet curtains draped like shadows, chandeliers flickering with unnatural light. The air hummed with static, as if reality itself had been rewired. Then, with a sudden crackle, the stage lights flared, and the first figure appeared.

Classic Sans slouched into existence, hoodie pulled tight, hands in his pockets. His grin was lazy, but his sockets scanned the room with sharp calculation. “heh... guess this ain’t my usual comedy gig,” he muttered, sinking into one of the front seats as if this were just another bad joke.

The silence broke with heavy boots. Fell Sans (Red) stormed in, crimson eye blazing like a warning flare. His posture screamed aggression, arms crossed, jaw clenched. “Tch. What kinda joke is this? Who dragged me here?” His voice was gravel, his aura hostile. He shot Classic a glare. “You. Don’t get smart with me.”

Classic raised his hands in mock surrender. “relax, pal. i didn’t plan the field trip.”

Then came a burst of cheer. Swap Sans (Blueberry) marched proudly, cape fluttering, voice booming: “Justice will prevail in this theater!” His optimism was almost too loud, bouncing against Fell’s growl. He struck a heroic pose, oblivious to the tension.

Swapfell Sans followed, sly grin curling. “Oh, look at this circus. Finally, a stage worthy of my performance.” His sarcasm dripped like poison, his eyes darting to Blueberry with disdain.

The air shimmered again, and Ink Sans bounced in, paintbrush twirling. “Ooooh, a theater! Perfect place for a crossover episode!” He sketched glowing doodles midair, giggling at his own theatrics. “This is gonna be fun!”

Static glitched across the room. Error Sans snapped into existence, strings twitching around his fingers. His voice fractured, rasping: “This... shouldn’t... exist.” His gaze locked onto Ink, hatred simmering. “You... did this.”

Ink twirled his brush innocently. “Moi? Nahhh. But hey, if it was me, you gotta admit — great set design!”

Golden light descended. Dream Sans floated gently, aura glowing like sunlight breaking through clouds. His voice was soft but firm: “Maybe... maybe this is a chance. A chance for us to understand each other.” His optimism clashed immediately against Fell’s hostility.

From the shadows, tendrils curled. Nightmare Sans emerged, smile sharp, venom dripping from every syllable. “Understand? Oh, Dream... you still cling to hope. How quaint.” His presence was suffocating, a magnetic pull that made several Sanses stiffen instinctively.

The theater buzzed as more arrived:

Classic sighed, sinking deeper into his seat. “welp. guess we’re all here. anyone got popcorn?”
