2011X is a central antagonist in modern Sonic.exe lore, reimagining Sonic as a sadistic, godlike entity who traps souls in a cursed game. The character gained traction through fan games, animations and horror edits shared on YouTube and TikTok in the early 2020s, building on the original 2011 Sonic.exe creepypasta. His laugh became a shorthand sound for the character online, detached from any single scene and reused in memes, fan dubs and soundboards whenever creators need an instantly recognisable evil Sonic moment.
