William Afton is the central villain of Five Nights at Freddy's, the horror game series created by Scott Cawthon that began in 2014. Known to fans as the Purple Guy, he is the co-founder of Fazbear Entertainment whose murders drive the story, later returning as the animatronic Springtrap. Clips tied to his name circulate widely on TikTok and meme soundboards, where the character's infamy does the heavy lifting. Editors reach for the name because FNAF lore remains a shared language online, keeping even short, low-context Afton clips in steady rotation years after the early games.
