Sonic.EXE began as a 2011 creepypasta about a haunted Sonic game, then spread through fan games, mods and horror videos that reimagined the character as a cruel villain. The 2011X version is a later fan reinterpretation, and this alternative laugh is one of several voice variants shared among creators for that take on the character. Clips using the laugh circulate in FNAF and other horror edits, gaming memes and fan animations, where its recognisable distortion instantly signals a corrupted Sonic without needing any visual explanation.
