Chara is the first fallen human in Undertale, the 2015 role-playing game by Toby Fox, and appears in a startling close-up during the game's darkest route. A recording of that loud, distorted moment began circulating on soundboards and in meme edits as a ready-made scare, often compared to the fnaf 2 scream for the same instant shock effect. Its short length and abrupt peak made it easy to hide at the end of quiet clips, and it remains a go-to prank sound for horror-themed jokes online.
