Sonic.EXE is a fan-made horror reinterpretation of Sega's Sonic the Hedgehog, born from creepypasta stories and fan games that turn the cheerful blue hedgehog into a demonic, godlike entity. The 'I am God' line captures that twisted power fantasy, and it has circulated widely in short horror edits, gameplay videos and meme compilations on YouTube and TikTok. Its popularity endures because it instantly signals a corrupted hero and a shift into horror, making it a shorthand for unsettling fan-made Sonic content.
