This sound is generally recognized online as an Undertale-related impact effect and is shared in meme edits, gameplay clips, and short videos. Undertale, the indie RPG released in 2015, has a distinctive audio style that made many of its battle sounds memorable and reusable. Clips labeled as heavy hit spread through fan uploads, compilations, and soundboards because they are short, dramatic, and easy to sync with visual action. It remains popular with creators who want a retro RPG feel without using a long piece of music.
