In Five Nights at Freddy's, the 'Purple Guy' is a representation of William Afton. He is a pixelated, purple-colored sprite shaped like a human, based on Afton's appearance in Five Nights at Freddy's 2 and 3. Fans initially named him 'Purple Guy' due to his purple sprite in the death minigames 'Take Cake to the Children' and 'Foxy Go! Go! Go!'
