Purple Guy, or Purple Man, is a recurring antagonist in the Five Nights at Freddy's series. He appears in FNAF 2 and FNAF 3 as the main antagonist of the game, and makes several cameo appearances in the rest of the series. He has also appeared as a major character in some of SMG4's character.
Purple Guy is prominently featured as one of Retarded64: Return to Freddy's Spaghettiria's main antagonists, the other being the Puppet. He attacked Mario in several minigames before appearing in the real world. Purple Guy attempts to use the Toy animatronics as slaves to kill Mario. The old animatronics start to fight the new ones; however, Purple Guy disables them before confronting Mario and preparing to kill him. Purple Guy then fights with the Puppet over who gets to kill Mario. Mario converts Mangle into the missile-shooting "Mangle Lawnchair", and chases the two villains. Mario then confronts Purple Guy before the Puppet punches him into the present box, which explodes moments later. Mario then kills Purple Guy and the Puppet.
Purple Guy once again plays a major role in Retarded64: Revenge of Freddy's Spaghettria, in which he controls the phantom animatronics and turns Mario into Animatronic Mario. He is scared out of his office into the old spaghettiria when he turns off Springtrap. While he at first taunts Mario and Luigi, he later dies inside the suit.
