Ceroba Ketsukane is a major character in Undertale Yellow, the fan-made prequel to Undertale released in December 2023 after years in development. As a grieving mother and boss encounter, her story is one of the game's most emotional arcs, and clips of her voice acting and in-game cries circulate in edits, reaction videos and soundboards. Fans reuse this scream outside its original scene because it instantly signals heartbreak, making it popular for memes that exaggerate sadness or a dramatic breakdown.
