Goner Kid

While Monster Kid is a chatty, cheerful classmate in Deltarune, Goner Kid is their unsettling, existential shadow. Goner Kid doesn't physically appear in Hometown, but they are a massive part of the lore connecting Undertale and Deltarune. Goner Kid’s Personality & Dialogue Unlike the high-energy Monster Kid, Goner Kid is melancholic, deeply lonely, and plagued by existential dread.They only appear as a rare, grayscale easter egg in Undertale's Waterfall area. When you speak to them, they deliver some of the most haunting lines in Toby Fox's games: "Have you ever thought about a world where everything is exactly the same... Except you don't exist? Everything functions perfectly without you... Ha, ha... The thought terrifies me." If you bring them an umbrella, they shift slightly from despair to resignation, telling you: "An umbrella...? But it's not raining. Ha, ha... You know, that makes me feel a little better. Thank you. Please forget about me." How They Connect to Deltarune"Goners" are entities scattered across time and space, heavily tied to the mystery of W.D. Gaster. Goner Kid impacts Deltarune through two major player theories: The "GONERMAKER" Connection: The very opening sequence of Deltarune—where you customize a gray vessel before a voice discards it—is named DEVICE_GONERMAKER in the game files. Fans believe Goner Kid is what happens to a person or a vessel when they are completely erased from a timeline. The "Monster Teen" Future: In Deltarune, Monster Kid has grown up slightly into an older, more cynical "Monster Teen". Because Goner Kid's design features mirrored head-spines and a ribcage-like shirt, fans theorize that Monster Teen might eventually be "erased" or fall into a Dark World bunker, transforming into the Goner Kid we meet out of order in Undertale.
