Omega Flowey is the final boss form of Flowey the Flower in Undertale, the 2015 role-playing game created by Toby Fox. In the Neutral Route ending, Flowey absorbs the human souls and transforms into a grotesque, screen-filling creature, accompanied by his distorted laugh. Clips of the fight spread through gameplay videos, fan art and remixes on YouTube and social media, and the laugh became a standalone shorthand for a cute character turning terrifying. It remains popular with Undertale fans for edits, streams and Halloween-style memes.
About this sound
Omega Flowey's distorted evil laugh from Undertale, the final boss form of Flowey. Used for villain reveals, jumpscares and chaotic meme edits.
This is Omega Flowey's maniacal laugh from Undertale, a high-pitched, distorted cackle layered with echo and glitchy effects that loops and rises in intensity. Played during his boss fight transformation, the sound feels unhinged rather than ordinary evil, mixing a child's giggle with something monstrous and broken. Its warped tone instantly signals danger, madness and loss of control, which is why a short burst works so well as a shock moment. Viewers familiar with the game recognise it immediately, while others still hear a clear villain laugh that unsettles and grabs attention.
