Fnaf Lore- MY OPINION by Bonnell376 Lyrics
Mid-1970s: William Afton marries an unknown wife, who some theories suggest to be Ballora, either by holding the wife's direct soul or being her recreation, and has two children: his daughter Elizabeth Afton and his son Michael Afton. It is also heavily implied and agreed by the community that he has a third child.
Late 1970s-Early 1980s: Henry Emily meets William Afton. He creates the animatronics Fredbear and Spring Bonnie and open a pizza location starring them with William, who manages, the business...The first Fredbear's Family Diner, which is probably opened in Utah where William lives.
May 13th, 1980: Henry has a daughter, Charlotte Emily.
c. 1980-1981: In Utah, William Afton founds Afton Robotics, interested in creating animatronic characters designed to capture and/or kill children.
c. 1981: Henry creates the Security Puppet to watch over his daughter. He also creates a second, slightly different model to the catalog Rare Finds Auction, as seen in Freddy Fazbear's Pizzeria Simulator where it is available for purchase.
c. 1975-1985*: William Afton opens Circus Baby's Pizza World, featuring Circus Baby, Bidybabs, humanoid animatronic Ballora and her Minireenas. Some fans also believe this is where Balloon Boy (BB), JJ and Dee Dee where first feature. It closes on it's opening day due to the death of Elizabeth Afton, William's daughter, who gets scooped by Baby, the scooper claw opening out of her stomach, and possesses her. William pretends it is due to gas leaks, perhaps out of grief. In my opinion, this most likely happens either in 1983 before BV's death or between that time and fnaf 2, around 1985.
Early 1983: Michael Afton** is kept up at night by 'Nightmare' variations of his fathers' animatronics: Nightmare Freddy, Bonnie, Chica, Foxy, BB (The fact Nightmare BB is canon supports the theory he was present at Circus Baby's), and Fredbear, as well as Nightmare, an even more Nightmarish version of Nightmare Fredbear. He is also haunted by Plushtrap, who at least is real. The non-canon nightmare animatronics are Nightmare Mangle and Nightmarrionne as the animatronics they are based off not exist at this point so they are non-canon. There are also Jack-O Nightmare animatronics: Jack-O-Bonnie and Jack-O-Chica, who are probably non-canon. All of this could be of the design of William to keep his children safe after the Circus Baby's Pizza World incident, or just nightmares by Michael. The Bite of 83' happens: the Bite Victim (who fans debate to be either Michael or his implied brother)'s head is bitten off by Fredbear on his birthday after being shoved in by his brother, who could be Michael Afton if we say BV is the third child. Either way, Fredbear's Family Diner closes. Believers of the "Mikevictim" and "Mikebot" theories believe William either revives his son using remnant or puts him back together as a robot, and they eventually will become Michael Afton.
(Presmued) Late 1983: Fazbear Entertainment is founded by Henry and William. They open their second location together, Freddy Fazbear's Pizza. For unknown reasons, William murders Henry's daughter, Charlotte Emily, outside of Fredbear's or Freddy's. This could happen before or after the Bite but I think it most likely happened after.
June 26th, 1983 or 1985: William sneaks into Freddy Fazbear's Pizza disguised as a security guard, with a crank, and decides to kill five kids***. First, he lures Susie, who possesses Chica, to her death by telling her her dog is not dead. Fans of the Mangle theory believe that William first runs over Susie's dog while she's busy playing the arcade game Fruity Maze, then experiments with it using Remnant and creates Mangle. He then uses the Spring Bonnie costume to gain the trust of the other four and kills them in the back room of Freddy's. This becomes known as the Missing Childrens' Incident.
1980s: The Puppet learns the secrets of remnant, and gives life to the children's spirits by stuffing 4 of them inside the 4 core Freddy's animatronics**** and infusing their spirits within them, and tries to create a 5th for the spirit that possesses Golden Freddy (Who many believe is called Cassidy based on the evidence below*^), which works, except the suit is poorly-made and flickers in and out of reality. According to one theory, Golden Freddy also becomes possessed by the Bite Victim.
c. 1986: William continues to sneak into the Pizzeria disguised as a security guard, using his springlock suit and crank to kill kids. Henceforth the anaimtronics want revemge on him. They will distrust at anyone in a security guard uniform or people who look like him and attack them, thinking them to be William. Customers start noticing blood and mucus coming from the animatronics, which leads to Freddy Fazbear's Pizza closing down and the company to be sold to unknown buyers. Fazbear Entertainment, in new hands now a larger company with more employees, finds the Puppet and decideds it'll be part of the next resteraunt, along with new, more advanced 'Toy' animatronics that William either secretly programs to kill, or are just malfunctioning. The old animatronics are kept for parts. They also either find or create Mangle, which, according to the mangledog theory, William has now abandoned, and Fazbear Entertainment are taking it as their own, although they say that it was a mangled version of Toy Foxy ripped apart by toddlers, which could be true. As a finishing touch, they either create or buy BB, a small plump little humanoid animatronic holding a sign saying 'Balloons!', his female counterpart JJ, and almost use a third animatronic they create, the annoying singing Dee Dee, but William probably gives it the power to summon almost any other animatronic, as seen in UCN and they discard it. Part of it's power is physically manifested into the eyeless, glitching XOR, or Shadow Dee Dee, or else the XOR of UCN is just a hallucination or metaphorical dark side of Dee Dee. This resteraunt is haunted by "Shadow" animatronics: Shadow Freddy and RWQFSFASXC/RWQ/Shadow Bonnie. They could be the victims of springlock failures, manifested into these creatures and haunting the resteraunt out of spite, that we know happened before the opening of the pizzeria, which we know happened. A few fans believe instead that Shadow Freddy is BV, but cannot explain Shadow Bonnie.
1987: The second Freddy Fazbear's Pizza opens. William, apparently pretending to be a security guard, proceeds to kill five more children at the New Freddy Fazbear's Pizza Location, who are heavily implied to then haunt the Toy Animatronics. Afterwards, William once again vanishes. The new resteraunt abruptly closes due to the new murders, as well as possibly the haunting of the Shadow animatronics.
November 8th 1987*****: Jeremy Fitzgerald is hired as a night-shift security guard for the new pizzeria. Phone Guy, another security guard, begins to record messages for him to help him survive the nights. He is occasionally theorized to be Michael Afton, although his motive other then money would be unknown and it is unlikely considering the Bite of 87'.
November 14th 1987: After 6 nights, Jeremy is moved to the day shift. Fritz Smith is hired as a night-shift security guard for Freddy Fazbear's Pizza, but is fired due to tampering with animatronics and odor. Shortly after this, Freddy's closes, but not before Jeremy's career is ruined. The Bite of '87 takes place Jeremy gets injured but doesn't die when his frontal lobe is bitten off, resulting in a major drop in business for Fazbear Entertainment. This incident also makes it unlikely that Michael is Jeremy as he would be missing his frontal lobe in later games. The animatronics are no longer allowed to walk around the building. It is still unknown who causes this, though the most popular theories in the fanbase are that Mangle or Withered Foxy are responsible.
c. Late 1987: Perhaps already in hope of becoming immortal, William lures the original anamatronics to the back safe room, dismantling them, experimenting on them, and using them to create the Funtime anamatronics, with renmants of the souls of the original murdered children, except for Bon-Bon, Funtime Freddy's handpuppet, who does not contain Jeremy's soul. Using these experiments, he creates Circus Baby's Pizza E&R (Entertainment and Rentals), which also includes the original Circus Baby's animatronics, a pink Bon-Bon called Bonnet, and helpful AI assistant HandUnit (The Handyman's Robotics and Unit Repair System Model 5.) After dismantling the animatronics and developing the new ones, the leftover or 'main' souls of the originals not in the Funtimes attack William after being freed from the metal suits that trap their souls. Fleeing from the spirits, William escapes into the safe room where Spring Bonnie has been placed for storage. He donns the suit to hide from the ghosts, apparently fooling them. In his arrogance, William stands and laughs at the ghosts while inside Spring Bonnie. However, the faulty mechanisms within Spring Bonnie malfunctions, causing William to be crushed and sliced by the endoskeleton and gears, brutally killing him. Phone Guy's tapes also foreshadow this; he explains that the person wearing the costumes must not get moisture on the springlocks or make sudden movements to decrease the chance of injury. Afton breaks these rules; he makes sudden movements by jumping into the suit, and fails to notice the rainwater seeping into the building and onto the springlocks. On top of that, he is laughing at the spirits, thinking his plan has succeeded. This results in the locks becoming loose by moisture, causing his slow and agonizing (first) death. The room in which this is happened is sealed off, perhaps by Henry.
c. 1996: Chica's Party World opens.
c. 1997: Chica's Party World closes, and Funtime Chica is sold to the catalog Rare Finds Auction (She is available in this catalog in FFPS)
4th December, 1993****** or 2003^: The new and probably fourth Freddy Fazbear's Pizza opens, with the old, withered models restored to proper working order. Mike Schimdt, who some many fans believe is actually Michael Afton under a fake name, is hired as a night-shift security guard for it, and with the help of Phone Guy learns to survive the animatronics.
8th December, 1993 or 2003: Phone Guy is killed by Freddy while recording one of his messages for Mike.
11th December, 1993 or 2003: Mike Schimdt is fired for animatronic tampering, odor and unprofessionalism. Then it closes, probably due to employee deaths or being unpopular.
c 2010 or 2020: Henry is recruited by Fazbear Entertainment to clean up the mess they've made.
2023 or 2033 (Exactly 30 years after FNAF 1): The Freddy Fazbear location reopens as a horror attraction, Fazbear's Fright. Phone Dude discovers the hidden room and sets Springtrap free. Someone, probably Michael, hired to murder Afton, so they burn it down. Springtrap, however, survives. With the help of BB, Mangle, Chica, Golden Freddy and Shadow Bonnie (as seen in the minigames), The Puppet brings Freddy, Bonnie, Chica, Foxy, the Mediocre Melodies (see below), and an unknown blue animatronic together to recreate a childhood party, and the spirits of the children who died in the Missing Children's Incident are finally freed.
c. 1990-2034: Michael (According to Mikebot Michael V. 2.0 (Robot Michael)) searches for his dad for answers. At Circus Baby's Pizza World, he meets Baby, possessed by Elizabeth Afton, but becomes a victim to the plot of the Funtime animatronics, which together form a wild mash-up called Ennard, a mad amalgam of Funtime Freddy/Bon-Bon, Funtime Foxy, Ballora and Baby, and scoop Michael just like his sister. He survives, though. The new version of Henry designs Lefty to capture the Puppet, and comes up with the trap to destroy the remaining animatronics. Springtrap, after the fire, rots and decays into Scraptrap, a weaker and less powerful animatronic.
c. 2025-6 or 2035-6: Cirus Baby is kicked out of Ennard by Ballora, Funtime Foxy and Funtime Freddy, and they seperate as Molten Freddy (Ennard's remains) and Scrap Baby. Henry creates a bait restaurant, Freddy Fazbear's Pizza Place, featuring new Mediocre Melodies (Happy Frog, Mr. Hippo, Nedd Bear, Orville Elephant, Pigpatch), Trash and the Gang animatronics (Bucket Bob, Mr. Can-Do, Mr. Hugs, No. 1 Crate, Pan Stan) and Rockstar animatronics as stars (Rockstar Freddy, Rockstar Bonnie, Rockstar Chica, Rockstar Foxy, Lefty). Funtime Chica, the Music Man and El Chip are later bought by the security guard, the bait for the animatronics (Almost all fans believe this is Michael, who volunteered to join Fazbear Entertainment to help create the resteraunt, although the job was not intended for him). Finally, he burns but also frees the spirits of Molten Freddy, Scraptrap and Lefty, and kills William, who is either sent to hell by Golden Freddy (Willhell) or simply dies. (Mikehell)
c. 2027 or 2037: Either William or Michael (the general consensus is William due to UCN vocelines) gets trapped in purgatory or hell by Henry and Golden Freddy (AKA The One You Should Not Have Killed) where 62 seperate characters^^ torment him.
c. 2034 or 2044: Glitchtrap hires Vanny into his cult, a reluctant follower who wears an eerie bunny mask. Many fans believe that uher true name is Vanessa, and Vanny is a portmanteau of "Vanessa" and "Bunny".^^^ (However, this also being the name of another character makes this unlikely.)
c. 2037 or 2047: Fazbear Entertainment creates The Freddy Fazbear Virtual Experience in hopes of forgetting the past. They hire Silver Parasol Games as the development team. During some phase of development, a play tester named Jeremy begins to act erratically, eventually chopping off his face with a guillotine paper slicer after witnessing a strange bug appear in the game...William Afton's soul gets embedded into the code, becoming a sentinent virus called Glitchtrap, who escpaes the game. Fazbear Entertainment also open the Fazbear Funtime Service, an animatronic rental company. This features all of these mad guys: ^^^^ Most of these animatronics regularly attack customers, either because of malfunctions, or being possessed by new dead spirits.
c. 2036-2040 or 2046-2050 (Security Breach date very hard to pinpoint, probs after everything else): Freddy Fazbear's Mega Pizzaplex opens. The security guard, Vanessa, is hired on.^^^^^ The animatronics featured at this location are Glamrock versions of Freddy and Chica, Montgomery Gator, Roxanne Wolf, a moon-themed animatronic and a similar sun-themed one. Vanny begins killing kids at this location under Glichtrap's control, and, after possibly killing his friends she hunts down the boy Gregory. Glamrock Freddy lets Gregory hide in his stomach, having a similar design to Funtime Freddy, to escape Vanny.
*Depending on your idea of the timeline.
**The Survival Logbook basically confirms it to be Michael who we play as in FNAF 4 as he draws Nightmare Fredbear on one of the pages.
***Their names are Gabriel, Susie, Fritz, Jeremy and the last victim's name is unknown, as in Freddy Fazbear's Pizzeria Simulator the grave is obscured by grass.
****Gabriel into Freddy, Susie into Chica, Jeremy into Bonnie, Fritz into Foxy.
****The date can be calculated from the date on the final paycheck of FNAF 2 and minusing a day for each night to find where it starts.
******Some deleted faz-facts from FNAF VR as well as calculations based off of the FNAF 1 paycheck suggest this. Also see later FNAF 6 evidence (^^)
^ ".... If I were forced to sing those same stupid songs for twenty years and I never got a bath?..." - Phone Guy. He probably wouldn't go as far to exaggerate 20 years if it were only 10, although this was early on in the series.
^^Freddy's closed at the end of the year, meaning if it took place in 1993 this would make FNAF 3 and FNAF 6 take place in late 2023 for 30 years to have passed as the steam page says.
^^^In the Insanity Ending, an image reading HRY223 can be seen while Henry is speaking. This could mean that this game takes place in the year 2023.
^^^^The steam page for FNAF 3 says that it takes place 30 years after Freddy Fazbear's closed, which happened in either 1993 or 2003. This would make the date 2023 or 2033
^^^^^For some reason, some people (but not many) who think that fnaf 1 is in 2003 and fnaf 3 is in 2033 seem to also place fnaf 6 around 2036. There isn't really any evidence for this but it's possible it takes place around three years after.

*^Fans believe Golden Freddy is called Cassidy because if you put numbers hidden throughout the Survival Logbook into the wordsearch grid (52 = 5 across 2 down = C, 39 = 3 across 9 down = A, 15 = 1 across 5 down = S, 7 2 = 7 across 2 down = S, 5+4=9 then the 3 = 9 across 3 down = I, 10 11 = 10 across 11 down - D, 8 11 = 8 across 11 down = Y) you get CASSIDY, which fans believe is GF's name beacsue IT'S ME is throughout the wordsearch, and each page with the numbers on has MY NAME written by a spirit many believe to be GF. Also MY NAME on one page is written on a gravestone in which the imagery matches up to FFPS's 5th grave, and in The Fourth Closet Cassidy ("A girl with short black hair") is mentioned, and a Logbook page referencing the Happiest Day minigame, where the Puppet gives cake to Golden Freddy, it is seen giving cake to a girl with short black hair.
^^^^^^^^This is backed up by the fact that in Five Nights at Freddy's AR: Special Delivery, a character called "Ness" is introduced. Ness has been stated to search disturbing content, such as subjects related to torture, "self-compliance", and "help". It is possible that she may actually be the Vanny, and the name "Ness" is an alias.

^^^^^^^^^Technically, Vanessa and Vanny can't be proven to be seperate characters completely (They probably do share a connection), but because of the Vanessa + Vanny statue, it can be assumed.
Late 1970s-Early 1980s: Henry Emily meets William Afton. He creates the animatronics Fredbear and Spring Bonnie and open a pizza location starring them with William, who manages, the business...The first Fredbear's Family Diner, which is probably opened in Utah where William lives.
May 13th, 1980: Henry has a daughter, Charlotte Emily.
c. 1980-1981: In Utah, William Afton founds Afton Robotics, interested in creating animatronic characters designed to capture and/or kill children.
c. 1981: Henry creates the Security Puppet to watch over his daughter. He also creates a second, slightly different model to the catalog Rare Finds Auction, as seen in Freddy Fazbear's Pizzeria Simulator where it is available for purchase.
c. 1975-1985*: William Afton opens Circus Baby's Pizza World, featuring Circus Baby, Bidybabs, humanoid animatronic Ballora and her Minireenas. Some fans also believe this is where Balloon Boy (BB), JJ and Dee Dee where first feature. It closes on it's opening day due to the death of Elizabeth Afton, William's daughter, who gets scooped by Baby, the scooper claw opening out of her stomach, and possesses her. William pretends it is due to gas leaks, perhaps out of grief. In my opinion, this most likely happens either in 1983 before BV's death or between that time and fnaf 2, around 1985.
Early 1983: Michael Afton** is kept up at night by 'Nightmare' variations of his fathers' animatronics: Nightmare Freddy, Bonnie, Chica, Foxy, BB (The fact Nightmare BB is canon supports the theory he was present at Circus Baby's), and Fredbear, as well as Nightmare, an even more Nightmarish version of Nightmare Fredbear. He is also haunted by Plushtrap, who at least is real. The non-canon nightmare animatronics are Nightmare Mangle and Nightmarrionne as the animatronics they are based off not exist at this point so they are non-canon. There are also Jack-O Nightmare animatronics: Jack-O-Bonnie and Jack-O-Chica, who are probably non-canon. All of this could be of the design of William to keep his children safe after the Circus Baby's Pizza World incident, or just nightmares by Michael. The Bite of 83' happens: the Bite Victim (who fans debate to be either Michael or his implied brother)'s head is bitten off by Fredbear on his birthday after being shoved in by his brother, who could be Michael Afton if we say BV is the third child. Either way, Fredbear's Family Diner closes. Believers of the "Mikevictim" and "Mikebot" theories believe William either revives his son using remnant or puts him back together as a robot, and they eventually will become Michael Afton.
(Presmued) Late 1983: Fazbear Entertainment is founded by Henry and William. They open their second location together, Freddy Fazbear's Pizza. For unknown reasons, William murders Henry's daughter, Charlotte Emily, outside of Fredbear's or Freddy's. This could happen before or after the Bite but I think it most likely happened after.
June 26th, 1983 or 1985: William sneaks into Freddy Fazbear's Pizza disguised as a security guard, with a crank, and decides to kill five kids***. First, he lures Susie, who possesses Chica, to her death by telling her her dog is not dead. Fans of the Mangle theory believe that William first runs over Susie's dog while she's busy playing the arcade game Fruity Maze, then experiments with it using Remnant and creates Mangle. He then uses the Spring Bonnie costume to gain the trust of the other four and kills them in the back room of Freddy's. This becomes known as the Missing Childrens' Incident.
1980s: The Puppet learns the secrets of remnant, and gives life to the children's spirits by stuffing 4 of them inside the 4 core Freddy's animatronics**** and infusing their spirits within them, and tries to create a 5th for the spirit that possesses Golden Freddy (Who many believe is called Cassidy based on the evidence below*^), which works, except the suit is poorly-made and flickers in and out of reality. According to one theory, Golden Freddy also becomes possessed by the Bite Victim.
c. 1986: William continues to sneak into the Pizzeria disguised as a security guard, using his springlock suit and crank to kill kids. Henceforth the anaimtronics want revemge on him. They will distrust at anyone in a security guard uniform or people who look like him and attack them, thinking them to be William. Customers start noticing blood and mucus coming from the animatronics, which leads to Freddy Fazbear's Pizza closing down and the company to be sold to unknown buyers.

Part of it's power is physically manifested into the eyeless, glitching XOR, or Shadow Dee Dee, or else the XOR of UCN is just a hallucination or metaphorical dark side of Dee Dee. This resteraunt is haunted by "Shadow" animatronics: Shadow Freddy and RWQFSFASXC/RWQ/Shadow Bonnie. They could be the victims of springlock failures, manifested into these creatures and haunting the resteraunt out of spite, that we know happened before the opening of the pizzeria, which we know happened. A few fans believe instead that Shadow Freddy is BV, but cannot explain Shadow Bonnie.
1987: The second Freddy Fazbear's Pizza opens. William, apparently pretending to be a security guard, proceeds to kill five more children at the New Freddy Fazbear's Pizza Location, who are heavily implied to then haunt the Toy Animatronics. Afterwards, William once again vanishes. The new resteraunt abruptly closes due to the new murders, as well as possibly the haunting of the Shadow animatronics.
November 8th 1987*****: Jeremy Fitzgerald is hired as a night-shift security guard for the new pizzeria. Phone Guy, another security guard, begins to record messages for him to help him survive the nights. He is occasionally theorized to be Michael Afton, although his motive other then money would be unknown and it is unlikely considering the Bite of 87'.
November 14th 1987: After 6 nights, Jeremy is moved to the day shift. Fritz Smith is hired as a night-shift security guard for Freddy Fazbear's Pizza, but is fired due to tampering with animatronics and odor. Shortly after this, Freddy's closes, but not before Jeremy's career is ruined. The Bite of '87 takes place Jeremy gets injured but doesn't die when his frontal lobe is bitten off, resulting in a major drop in business for Fazbear Entertainment.

Late 1987: Perhaps already in hope of becoming immortal, William lures the original anamatronics to the back safe room, dismantling them, experimenting on them, and using them to create the Funtime anamatronics, with renmants of the souls of the original murdered children, except for Bon-Bon, Funtime Freddy's handpuppet, who does not contain Jeremy's soul. Using these experiments, he creates Circus Baby's Pizza E&R (Entertainment and Rentals), which also includes the original Circus Baby's animatronics, a pink Bon-Bon called Bonnet, and helpful AI assistant HandUnit (The Handyman's Robotics and Unit Repair System Model 5.) After dismantling the animatronics and developing the new ones, the leftover or 'main' souls of the originals not in the Funtimes attack William after being freed from the metal suits that trap their souls.

On top of that, he is laughing at the spirits, thinking his plan has succeeded. This results in the locks becoming loose by moisture, causing his slow and agonizing (first) death. The room in which this is happened is sealed off, perhaps by Henry.
c. 1996: Chica's Party World opens.
c. 1997: Chica's Party World closes, and Funtime Chica is sold to the catalog Rare Finds Auction (She is available in this catalog in FFPS)
4th December, 1993****** or 2003^: The new and probably fourth Freddy Fazbear's Pizza opens, with the old, withered models restored to proper working order. Mike Schimdt, who some many fans believe is actually Michael Afton under a fake name, is hired as a night-shift security guard for it, and with the help of Phone Guy learns to survive the animatronics.
8th December, 1993 or 2003: Phone Guy is killed by Freddy while recording one of his messages for Mike.
11th December, 1993 or 2003: Mike Schimdt is fired for animatronic tampering, odor and unprofessionalism. Then it closes, probably due to employee deaths or being unpopular.
c 2010 or 2020: Henry is recruited by Fazbear Entertainment to clean up the mess they've made.
2023 or 2033 (Exactly 30 years after FNAF 1): The Freddy Fazbear location reopens as a horror attraction, Fazbear's Fright. Phone Dude discovers the hidden room and sets Springtrap free. Someone, probably Michael, hired to murder Afton, so they burn it down. Springtrap, however, survives. With the help of BB, Mangle, Chica, Golden Freddy and Shadow Bonnie (as seen in the minigames), The Puppet brings Freddy, Bonnie, Chica, Foxy, the Mediocre Melodies (see below), and an unknown blue animatronic together to recreate a childhood party, and the spirits of the children who died in the Missing Children's Incident are finally freed.
c. 1990-2034: Michael (According to Mikebot Michael V. 2.0 (Robot Michael)) searches for his dad for answers. At Circus Baby's Pizza World, he meets Baby, possessed by Elizabeth Afton, but becomes a victim to the plot of the Funtime animatronics, which together form a wild mash-up called Ennard, a mad amalgam of Funtime Freddy/Bon-Bon, Funtime Foxy, Ballora and Baby, and scoop Michael just like his sister. He survives, though. The new version of Henry designs Lefty to capture the Puppet, and comes up with the trap to destroy the remaining animatronics. Springtrap, after the fire, rots and decays into Scraptrap, a weaker and less powerful animatronic.
c. 2025-6 or 2035-6: Cirus Baby is kicked out of Ennard by Ballora, Funtime Foxy and Funtime Freddy, and they seperate as Molten Freddy (Ennard's remains) and Scrap Baby. Henry creates a bait restaurant, Freddy Fazbear's Pizza Place, featuring new Mediocre Melodies (Happy Frog, Mr. Hippo, Nedd Bear, Orville Elephant, Pigpatch), Trash and the Gang animatronics (Bucket Bob, Mr. Can-Do, Mr. Hugs, No. 1 Crate, Pan Stan) and Rockstar animatronics as stars (Rockstar Freddy, Rockstar Bonnie, Rockstar Chica, Rockstar Foxy, Lefty). Funtime Chica, the Music Man and El Chip are later bought by the security guard, the bait for the animatronics (Almost all fans believe this is Michael, who volunteered to join Fazbear Entertainment to help create the resteraunt, although the job was not intended for him). Finally, he burns but also frees the spirits of Molten Freddy, Scraptrap and Lefty, and kills William, who is either sent to hell by Golden Freddy (Willhell) or simply dies. (Mikehell)
c. 2027 or 2037: Either William or Michael (the general consensus is William due to UCN vocelines) gets trapped in purgatory or hell by Henry and Golden Freddy (AKA The One You Should Not Have Killed) where 62 seperate characters^^ torment him.
c. 2034 or 2044: Glitchtrap hires Vanny into his cult, a reluctant follower who wears an eerie bunny mask. Many fans believe that uher true name is Vanessa, and Vanny is a portmanteau of "Vanessa" and "Bunny".^^^ (However, this also being the name of another character makes this unlikely.)
c. 2037 or 2047: Fazbear Entertainment creates The Freddy Fazbear Virtual Experience in hopes of forgetting the past. They hire Silver Parasol Games as the development team. During some phase of development, a play tester named Jeremy begins to act erratically, eventually chopping off his face with a guillotine paper slicer after witnessing a strange bug appear in the game...William Afton's soul gets embedded into the code, becoming a sentinent virus called Glitchtrap, who escpaes the game. Fazbear Entertainment also open the Fazbear Funtime Service, an animatronic rental company. This features all of these mad guys: ^^^^ Most of these animatronics regularly attack customers, either because of malfunctions, or being possessed by new dead spirits.
c. 2036-2040 or 2046-2050 (Security Breach date very hard to pinpoint, probs after everything else): Freddy Fazbear's Mega Pizzaplex opens. The security guard, Vanessa, is hired on.^^^^^ The animatronics featured at this location are Glamrock versions of Freddy and Chica, Montgomery Gator, Roxanne Wolf, a moon-themed animatronic and a similar sun-themed one. Vanny begins killing kids at this location under Glichtrap's control, and, after possibly killing his friends she hunts down the boy Gregory. Glamrock Freddy lets Gregory hide in his stomach, having a similar design to Funtime Freddy, to escape Vanny.
*Depending on your idea of the timeline.
**The Survival Logbook basically confirms it to be Michael who we play as in FNAF 4 as he draws Nightmare Fredbear on one of the pages.
***Their names are Gabriel, Susie, Fritz, Jeremy and the last victim's name is unknown, as in Freddy Fazbear's Pizzeria Simulator the grave is obscured by grass.
****Gabriel into Freddy, Susie into Chica, Jeremy into Bonnie, Fritz into Foxy.
****The date can be calculated from the date on the final paycheck of FNAF 2 and minusing a day for each night to find where it starts.
******Some deleted faz-facts from FNAF VR as well as calculations based off of the FNAF 1 paycheck suggest this. Also see later FNAF 6 evidence (^^)
^ ".... If I were forced to sing those same stupid songs for twenty years and I never got a bath?..." - Phone Guy. He probably wouldn't go as far to exaggerate 20 years if it were only 10, although this was early on in the series.
^^Freddy's closed at the end of the year, meaning if it took place in 1993 this would make FNAF 3 and FNAF 6 take place in late 2023 for 30 years to have passed as the steam page says.
^^^In the Insanity Ending, an image reading HRY223 can be seen while Henry is speaking. This could mean that this game takes place in the year 2023.
^^^^The steam page for FNAF 3 says that it takes place 30 years after Freddy Fazbear's closed, which happened in either 1993 or 2003. This would make the date 2023 or 2033
^^^^^For some reason, some people (but not many) who think that fnaf 1 is in 2003 and fnaf 3 is in 2033 seem to also place fnaf 6 around 2036. There isn't really any evidence for this but it's possible it takes place around three years after.

*^Fans believe Golden Freddy is called Cassidy because if you put numbers hidden throughout the Survival Logbook into the wordsearch grid (52 = 5 across 2 down = C, 39 = 3 across 9 down = A, 15 = 1 across 5 down = S, 7 2 = 7 across 2 down = S, 5+4=9 then the 3 = 9 across 3 down = I, 10 11 = 10 across 11 down - D, 8 11 = 8 across 11 down = Y) you get CASSIDY, which fans believe is GF's name beacsue IT'S ME is throughout the wordsearch, and each page with the numbers on has MY NAME written by a spirit many believe to be GF. Also MY NAME on one page is written on a gravestone in which the imagery matches up to FFPS's 5th grave, and in The Fourth Closet Cassidy ("A girl with short black hair") is mentioned, and a Logbook page referencing the Happiest Day minigame, where the Puppet gives cake to Golden Freddy, it is seen giving cake to a girl with short black hair.
^^^^^^^^This is backed up by the fact that in Five Nights at Freddy's AR: Special Delivery, a character called "Ness" is introduced. Ness has been stated to search disturbing content, such as subjects related to torture, "self-compliance", and "help". It is possible that she may actually be the Vanny, and the name "Ness" is an alias.

^^^^^^^^^Technically, Vanessa and Vanny can't be proven to be seperate characters completely (They probably do share a connection), but because of the Vanessa + Vanny statue, it can be assumed.
