Undertale was released in 2015 as an indie role-playing game created by Toby Fox, known for battles where players dodge attacks in a small box around a heart representing their soul. Its damage cue became familiar through repeated encounters, boss fights, and playthrough videos shared online. As Undertale clips, remixes, and fan edits spread on video and streaming platforms, creators lifted the short hurt sound for use outside the game. It remains popular because even listeners who have never played recognize its harsh tone as an immediate signal of taking a hit.
