Bonnie

Bonnie (also fully known as Bonnie the Rabbit or Bonnie the Bunny, by fans) is an antagonist in Five Nights at Freddy's. Bonnie is an animatronic rabbit and children's entertainer housed at Freddy Fazbear's Pizza, along with Freddy Fazbear and Chica. He is the guitarist in Freddy's band, positioned at the left side. At midnight, he is left in a "free-roaming mode" until 6 AM, to prevent his servos from locking up.

Along with the other animatronics, Bonnie will try to forcefully stuff any human he sees after hours into a Freddy Fazbear suit, resulting in death.

Five nights at Freddy's 1
Bonnie's starting location is the Show Stage, along with his bandmates Freddy and Chica. Upon activation, he will move to any room on the left side of the restaurant, excluding Pirate Cove. This means he can appear in the Dining Area, Backstage, the West Hall, the Supply Closet, and the West Hall Corner. When looking into the Office, he appears, leaning into the left doorway from the blind spot directly behind the left door.

Bonnie is known for coming and returning to The Office more frequently than the other animatronics, and, like Foxy, he only approaches from the left side - though their similarities end there. He will stare through the doorway into The Office, unlike Chica, who looks through the window. As opposed to Chica, Bonnie usually shows up at the door more frequently, but leaves more quickly than Chica, thus draining less power.

On some nights, if the player does not look at Bonnie on the Show Stage, he will not move from that location. Although this is one of the best methods for surviving after Night 2, using this method leaves the player unable to check on Pirate Cove (as the Show Stage is the default camera when opening the Monitor), leaving the player vulnerable to an attack from Foxy.

On the 4th, 5th, 6th, and 7th nights, while standing in front of the camera outside the Office (CAM 2B), Bonnie's head and jaw twitch violently in a very paranormal manner. The Robotvoice sound byte can be heard while he is twitching, even if the player is not looking at him directly on the Monitor. These paranormal behaviors are also exhibited by Chica.

When Bonnie enters the Office while the player is viewing the cameras, quiet, raspy, groan-like noises are audible. Once the player lowers the camera view and returns to the Office, Bonnie will attack them and cause a Game Over. The same noises can also be heard in this situation if Chica is waiting to attack. Bonnie and Chica are capable of forcing the player to lower the Monitor to attack, meaning the night guard cannot necessarily survive by continuing to view the Monitor until 6 AM as previously thought.

Unlike Chica, who can only travel to adjacent rooms throughout the building, Bonnie appears to possess supposed teleportation abilities, which is noticeable with Cheat Mode (Android version only) enabled. This is seemingly responsible for him appearing at The Office door far more often than Chica does. Additionally, Bonnie is also capable of temporarily disabling the cameras as he moves to another area, as is Chica.

Five nights at Freddy's 2
Bonnie's older model (also known as Withered Bonnie and referred to in catalog as Bonnie the Rabbit (Withered Version) makes an appearance in Five Nights at Freddy's 2, along with the three other older animatronics who have all fallen into severe disrepair. He is replaced by his newer counterpart for the "improved" Freddy Fazbear's Pizza, Toy Bonnie.

Bonnie's old model has a very different design - like Freddy Fazbear, he also has two buttons on his chest. His face has been gutted, with most of it being removed, revealing his endoskeleton mechanisms and dangling wires. His lower jaw remains, featuring more teeth than he possessed in the first game. His eyeballs are gone, exposing glowing red irises. His left arm is missing entirely, baring a tiny strip on the topmost section, with a mass of torn wires in its place. The red layering of his mouth has been removed, making his teeth seem longer than before.

His suit has become tattered, particularly around the legs, and a few loose wires poke out of his body. The covering on his right hand and left foot have come off, revealing more of his endoskeleton. He also seems to have a bigger stomach, as it looks more rounded and bigger than his upper body. Also, his chin does not squash his bow tie now, and his suit seems to have changed to a darker shade of blue. Like his appearance from the first game, he also wears a red bowtie.

According to Phone Guy on Night 2, Bonnie's appearance is due to an attempted retrofit of the older animatronics that took place before they got scrapped for the newer models, such as Toy Bonnie.

Like Freddy and Chica, Bonnie is an incredibly active animatronic, as he can leave the Parts/Service room as early as 12 AM and can sneak into the Office around 3 times in an hour. Unlike in the first game, Bonnie follows a fixed path and no longer teleports along his attack route. He starts moving at Night 2 but is very inactive until Night 3. Bonnie starts with the other older animatronics in the Parts/Service room and travels to the Main Hall. He then heads to the hallway outside the Office, staring at the night guard from just outside. After that, he travels into Party Room 1 to climb into the Left Air Vent to enter the Office, completely bypassing the Left Air Vent's blind spot.

When Bonnie is in The Office and either the player lowers their Monitor or Bonnie forces it down, Bonnie will stand in front of the desk as the lights constantly flicker before he vanishes. The player has less than a second (even in earlier nights) to put on the Freddy Fazbear Head the moment they see him to avoid imminent death. Delaying or neglecting to put the head on will cause the screen to black out as normal, only for Bonnie to return and kill the night guard after they lower the Monitor. Just like the other animatronics, he may also forcibly pull down the Monitor or remove the Freddy Head if left on sometime after failing to ward him off. After he is warded off when the player equips the head, Bonnie returns to the Main Hall and his cycle repeats.

Five nights at Freddy's 3
Bonnie returns in Five Nights at Freddy's 3. Like the other animatronics, he appears as one of the attractions at Fazbear's Fright. His remains can be seen at CAM 02.

Unlike the other animatronics, his role is not majorly replaced by a phantom. His role is replaced by Springtrap, who is Bonnie's original version.

Posters of Bonnie can be seen inside the Office, CAM 02, CAM 05, and CAM 09.

There is a Bonnie-themed arcade cabinet located at CAM 06.

The drawing from CAM 08 and inside the Office appears to feature an unusual-looking Bonnie holding a cupcake, similar to Chica.

From the Office, Bonnie's figurine is seen on the desk along with two other figurines.

Bonnie's head, along with three (four during the Bad Ending), appears in the ending screens after completing all five nights.

Bonnie makes an additional appearance in the end-of-night minigames. Upon completing each night, the player will be taken to a short minigame with graphics similar to old Atari gaming systems, during which they must navigate a map of the pizzeria from the first game.

On Night 2, the player will play as Bonnie, appearing on the Show Stage accompanied by Chica. When they leave the Stage and enter any other room, they will encounter what appears to be Shadow Freddy, instructing the player to follow it. It will lead them to a room in the east side of the restaurant, and the player will see Freddy's remains scattered on the floor from the previous minigame.

Shadow Freddy will enter a room which is inaccessible to the player (they will receive an "ERR" message and be bounced back if they try to enter it). As in the previous minigame, if they try to walk away, the Purple Guywill rush out and attack Bonnie, dismantling him before the minigame abruptly ends.

During the end-of-night minigames on Night 3, 4, and 5, Bonnie's remains can be seen scattered throughout the same room he was dismantled in.

From the "Happiest Day" minigame, one of the children at the end of the minigame is seen wearing Bonnie's mask.

Five nights at Freddy's 4
Like most of the other original animatronics, Bonnie himself does not make any major appearance in Five Nights at Freddy's 4. The plushie of him can be seen in some minigames after completing each night. The other appearance is when he appears on the TV on the Night 2 minigame, on what is either an advertisement or TV show titled "Fredbear & Friends!".

From the end-of-night minigame after beating Night 5, one of the protagonist's older brother's friends is seen wearing Bonnie's mask.

Rather than appearing as himself, Bonnie is majorly replaced with his nightmarish counterpart, Nightmare Bonnie.

Appearance
Bonnie is a purple bunny, wears a red bowtie, and red eyes.
