Sonic.exe started as a fan-made creepypasta version of Sonic the Hedgehog, reimagined as a demonic, red-eyed entity, and he later became a popular antagonist in Friday Night Funkin' mods, where his distorted laugh became instantly recognisable. Clips of the laugh spread through YouTube edits, TikTok videos and gaming montages, often used in the same way as a jumpscare scream to mark a sudden horror moment. It remains popular because fans of both Sonic and Friday Night Funkin' recognise it immediately, even without any visuals.
