William Afton is the central villain of Five Nights at Freddy's, the horror game series created by Scott Cawthon and first released in 2014. As the co-founder of Fazbear Entertainment and the killer behind the series' missing children cases, he became known to fans as the Purple Guy and a symbol of hidden guilt. Clips built around him circulate widely in fan edits, lore videos, and short-form memes, where his name alone signals a twist, a betrayal, or a culprit finally being named.
