— A critique of Afton’s animatronic designs.

William Afton (also commonly known as Purple Guy, The Killer, or The Murderer, or Mr. Afton) is the overarching main antagonist of the Five Nights at Freddy's series.

He was responsible for The Missing Children Incident mentioned in Five Nights at Freddy's, and he may have carried out more murders, as implied by the Death Minigames in the second game. He appears in most of the Death Minigames of the second game and the End-of-Night Minigames of the third and fourth game, and his role in the franchise's story is pivotal.


William Afton's appearance in the minigames is represented with the size and height of an adult man, and with his skin tone ranging from various tones of purple or magenta, depending on the minigame, however it is important to note that his skin tone might actually not be purple or magenta but is only represented in this way.

He is also sometimes depicted wearing a yellow accessory on his chest, presumably a badge. It isn't until Five Nights at Freddy's 3 that he retained a consistent appearance, undetailed as it may be, though he has expressive eyes and a mouth that conveys his emotional state.

Another instance in which William shows more detail than his other appearances is during the SAVETHEM Death Minigame, in which he has glowing, white eyes, a yellow object on his chest which resembles a badge and either, holds a purple object, which is speculated to be a weapon or tool, or extends his hand in a beckoning pose.

Object Speculation

There is quite a bit of fan speculation about the mysterious object William holds in his "You can't" sprite. Others believe it to be a weapon, as it is used to attack (and seemingly disable) Freddy Fazbear, such as a screwdriver, hammer, crowbar, or even a taser. Evidence to support the taser is that the death minigame ends immediately after William touches Freddy with the object and that the static when the minigame ends is blue instead of the usual red.

Some fans believe it was some sort of tool used while hacking into the animatronics' facial recognition systems, or the crank used for the spring animatronics, but are unspecific as to exactly what the tool is and how it aids in hacking. This is somewhat supported with the Night 4 phone call. Some assume it is just his hand in a beckoning stance, as it is the same color as his body.


William is the murderer of the five children that sparked the downfall of Fazbear Entertainment, and started the chain of events that leads players through the series. William's personality and motives are left very cryptic.


  • Due to the significant changes made to the mobile ports, the second game's mobile version is the only mobile port in the series where William has a major role, as he only makes an appearance in the third game's mobile version in the rare Springtrap boot screens, whereas in the fourth game's mobile version he is absent.

William Afton returns in Five Nights at Freddy's 3 as Springtrap.


William's physical in-game appearance is very limited, due to the vast majority of his corpse being trapped within the Spring Bonnie suit as Springtrap and therefore heavily concealed within the suit.


On the first four end-of-night minigames, William will dismantle the animatronics when they attempt to go to the Safe Room. Upon attempting to enter the room, the "ERR" message will be displayed. If they do not enter the room, William will dismantle them regardless.

On Night 5, however, five spirits appear and enter the Safe Room along with William. After chasing him for a while, he runs into the Spring Bonnie suit. He is crushed to death in the suit due to the malfunctioning springlocks, and the spirits disappear. He will later be revived as Springtrap during the events of the third game.


  • Occasionally, when the third game starts up, one of three images may appear of Springtrap revealing the William's rotting corpse inside of him, similarly to the eyeless Bonnie screen from the first game and the eyeless screens from the second game.
    • Part of William's lower jaw can also briefly be seen in Springtrap's right-side jumpscare, and while he is in sight on CAM 15.
  • With assorted parts of his flesh visible, William is the second human character to make any sort of on-screen appearance, after Mike Schmidt (as his eyes and teeth are visible in the Game Over screen in the first game).
    • With these visible parts of his body, some discerning features can be made out in William, such as a cleft chin.
    • Along with that, William is also the only character who has revealed more of an on-screen appearance (that being the Jumpscares, Extras, and rare boot screens).
  • At the end of night Minigames, Shadow Freddy will lead the player to the room where they meet their imminent fate at the hands of William. Furthermore, if the player restrains from following Shadow Freddy for too long, William will come and dismember them anyway. This seems to suggest that this Shadow Freddy may be William, this is further supported by the fact that they are never seen together as well as the reason he leads the player to the room, but until more information can be gathered, no legitimate theories can be confirmed.
  • The code for Night 4's minigame in Five Nights at Freddy's 3 (395248) is the hex code of purple in reverse (#842593).
  • Many fans speculate that the child who cornered William was the fifth child previously seen in the Give Gifts, Give Life Death Minigame, in the second game, and Happiest Day minigame in the third game.
  • Unlike most human characters in the series, William Afton speaks using a southeastern British Accent. According to an interview between YouTube Personality Lewis Dawkins, AKA Dawko, and Afton's voice provider, PJ Heywood, the latter based Afton's personality upon Anthony Hopkin's portrayal of Hannibal Lecter from Silence of the Lambs.

While William Afton does not appear as an antagonist in Five Nights at Freddy's 4, he does makes a cameo in what may be Fredbear's Family Diner at the end of Night 3, where, if the player goes back to the Dining Room when the man in the Fredbear suit is first seen, William appears to be helping an employee into a Spring Bonnie suit.


William appears similar to how he did in SAVETHEM, except he no longer has a smile on his face and has a name tag instead of a badge.

William Afton does not appear anywhere in Five Nights at Freddy's: Sister Location, albeit his voice heard during the opening intro where he describes Circus Baby's abilities.


  • William Afton is voiced by PJ Heywood, who also voiced Michael from the final cutscene ending, and later for William's second reanimated incarnation in Freddy Fazbear's Pizzeria Simulator.
  • Michael Afton as a corpse in the final minigame cutscene bears an eerie resemblance to William Afton's minigame sprites from the previous installments.
  • As opposed to his second reanimated incarnation, Afton's voice sounds noticeably more smooth than future games, in which his voice sounded more gravelly.

William Afton once again appeared in Freddy Fazbear's Pizzeria Simulator, as the second incarnation of Springtrap, with noticeable differences from the original Springtrap model.

Both of William Afton's incarnations return in the mashup Ultimate Custom Night.

As William appears in many minigames, he makes various noises when performing different actions. The sound effects played are as follows:


Warning: Loud!
The sound played when William charges at an animatronic to dismantle it. It also plays on the three rare Springtrap boot screens.

Crazy garble

The sound played when William is fleeing from the dead children.


The sound played when William is crushed inside Springtrap.


The sound played when William is in the Springtrap suit, presumably laughing at the children.


William moaning inside of Springtrap while he moves.



A board member (first) and William Afton (second) talking about Circus Baby in the intro to FNaF Sister Location:

Board Member:

There’s no doubting what you’ve achieved on a technical level. These are clearly state-of-the-art. There are just certain design choices that were made for these robots that we don’t fully understand. We were hoping that you could shed some light on those.

William Afton:

She can dance, she can sing! She’s equipped with a built-in helium tank for inflating balloons right at her fingertips. She can take song requests. She can even dispense ice-cream.

Board Member:

With all due respect, those aren’t the design choices we were curious about, Mr Afton.
