Chica

Chica (also fully known as Chica the Chicken) is an antagonist in Five Nights at Freddy's. Chica is an animatronic chicken and children's entertainer housed at Freddy Fazbear's Pizza, along with Freddy Fazbear and Bonnie. She is the backup singer standing on the right-side in Freddy's band. At midnight, she is left in a "free roaming mode" until 6 AM, to prevent her servos from locking up.

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

Five nights at Freddy's 1
Like Bonnie and Freddy, Chica starts the night on the Show Stage. When she leaves the Show Stage, Chica may then go to the Kitchen, Restrooms, Dining Area, and East Hall.

Her movements are somewhat random, but she always approaches from the right side. The player can activate the Hall Lights to check if she's in the blind spot.

As Chica gets closer to the Office, her jaw opens wider as she nears. Chica also seems to twitch wildly when she's at the East Hall Corner, though this only occurs on the fourth, fifth, and sixth night, as well as on the Custom Night.

She's also the only animatronic who can access the Kitchen area on the first two nights (as Freddy, who is the only other animatronic who enters the Kitchen, does not become active until the third night). A clashing of pots and pans will be audible, and Chica will not be visible in any other room.

Chica will generally head towards the night guard's position, similar to Bonnie, but she also wanders to the Kitchen and Restrooms. As opposed to Bonnie, Chica will show up at the door less often, but will generally linger there, waiting longer and stealing more of the player's energy, whereas Bonnie will show up more often but leave quickly.

Like the others, she becomes more aggressive as the nights progress, with the amount of time the player has to close the door before she enters decreasing.

If the player fails to check the right-side blind spot and close the door while she's at the window, she will sneak into The Office, though she cannot be seen. After she accesses the Office, the buttons to both the door and light on the right side of the Office will no longer function, but rather play an error sound when activated. Another indication that Chica has entered the Office is by listening for groaning sounds that both she and Bonnie make when waiting for the player to lower the Monitor.

During this phase, she will attack the night guard as soon as they lower the Monitor. The only way to survive the night after this occurrence is to not view the Monitor for the remainder of the night or to avoid lowering it if they're close enough to 6 AM, though Chica may still manually pull down the Monitor regardless as to whether or not the player pulls it down themselves.

On later nights, when Chica is in the East Hall Corner, her appearance becomes more erratic. Her head will twitch violently, her eyes will blink rapidly, her mouth will snap open and closed and she will emit the robotic voice sound byte regardless of whether or not the player has the Monitor focused on her.

Unlike Bonnie, who can teleport around the pizzeria, Chica can only move to adjacent rooms. This is especially noticeable with Cheat Mode enabled in the Android version.

Five nights at Freddy's 2
Chica's older model (also known as Withered Chica referred to in catalog as Chica the Chicken (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. She is replaced by her newer counterpart for the "improved" Freddy Fazbear's Pizza, Toy Chica.

Like Bonnie and Freddy, Chica is an incredibly active animatronic, as she 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, Chica follows a set path. She will begin moving from Night 3 onward, but can rarely make an appearance on Night 2. Chica starts with the other older animatronics in the Parts/Service room, moving to Party Room 4 and then Party Room 2 to enter the Right Air Vent. While in the Right Air Vent, as Bonnie does, she completely bypasses the vent's blind spot and may enter The Office while the Monitor is pulled up.

When she is in The Office and the player lowers the Monitor, or when she forces it down, Chica will stand in front of the desk as the lights constantly flicker before she vanishes. The player must immediately put on the Freddy Fazbear Head the moment they see Chica to avoid imminent death. Delaying or neglecting to put the Head on will cause the screen to black out as normal, only for her to return and kill the night guard after bringing up and lowering the Monitor or taking off the Freddy Head. She may also forcibly pull down the Monitor or remove the head if left on some time after failing to ward her off. Once the player equips the head and Chica leaves, she returns to Party Room 4, and her cycle repeats.

Five nights at Freddy's 3
Posters of Chica can be seen inside the Office, CAM 02, and CAM 05. From inside the Office, a drawing of Chica popping out from the cake can be seen at the far right.

From the Office, Chica's figurine can be seen at the right with two other figurines.

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

Chica also makes an 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 the third night, the player will play as Chica, now appearing all alone on the Show Stage. If 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 pizzeria, and the player will see Freddy and Bonnie's remains scattered on the floor from the previous minigames.

Shadow Freddy will enter a room which is inaccessible to the player (they will receive an "ERR" message if they try to enter it). As in the previous minigames, if they try to walk away, then Purple Guy will rush out and dismantle Chica, and the minigame ends.

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

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

Five nights at Freddy's 4
Like most of the other original animatronics, Chica herself does not make any major appearance in Five Nights at Freddy's 4. The plushie of her can be seen in some minigames after completing each night. The other appearance is when she 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 completing Night 5, one of the protagonist's older brother's friends is seen wearing Chica's mask.

Rather than appearing as herself, Chica is majorly replaced with her nightmarish counterpart named Nightmare Chica. Her Cupcake is also replaced by its nightmarish variant as well.

Appearance
Chica is a yellow chicken, has purple eyes, has orange feets and beak, wears a bib.
