Deltarune Fanfiction

Toby Fox's episodic follow-up to Undertale sends Kris, Susie and Ralsei into Dark Worlds while something unsettling steers Kris's body between chapters. The fandom theorizes as hard as it writes: fics dig into Kris's resentment of the player, Susie's softening, Noelle's Snowgrave trauma, and Spamton's garbage-noise tragedy. Chapter gaps give writers room to run, so the archive brims with predicted Dark Worlds, Dess Holiday backstory, and quiet Hometown slice-of-life between adventures.
