Jimmy chica

Her older, withered form, Withered Chica, first appears in Five Nights at Freddy's 2, then later returns in Ultimate Custom Night and Five Nights at Freddy's VR: Help Wanted as an antagonist. She, along with the four other older animatronics have all fallen into severe disrepair and she is replaced by her newer counterpart (Toy Chica) for the "improved" Freddy Fazbear's Pizza due to going through an attempted retrofit and subsequent abandonment of the older model, in favor of Toy Chica, according to Phone Guy on Night 2. For a start, the feminine features have been toned down, and she appears more androgynous as a result, to contrast her more with Toy Chica. Her body seems to have minimal changes. Her beak has a jaw similar to the ones Withered Bonnie and Withered Freddy have, which appears to be completely unhinged. Her beak is also more pointed, like that of an actual chicken, and she has even more teeth on her upper and lower beak. The infamous second set of teeth from the animatronic endoskeleton is also clearly visible and covered in blood. She has two stumps where her hands used to be, with long wires pouring forth.

Personality
Based on the Freddy Fazbear's Pizza Theme Song song, Chica is a pushy, gluttonous but lovable singing animatronic bot who has love for food, especially pizza. The Pizza Party level in Night Terrors also demonstrates this by actively eating pizza from a room that appears to be the kitchen, and in the first game, one can hear clanging sounds emanating from the kitchen. In both occasions, she was distracted by her goal of killing the player, implying that her gluttony can distract her at times. According to HandUnit's instructions in "Parts and Service: Chica", she still maintains her gluttonous tendencies as she is covered in pizza.

Chica also seems to be very pushy and determined, as when she gets to the night guard's door, she will stay there for long periods of time far longer than Bonnie would.

As Withered Chica, in Ultimate Custom Night, she seems to be a contemptuous survivor, feeling strangely aware of the fact that she is damaged. Her voice has a lot of ominous buzzing and fan-like noises in the background. One of her voice lines heavily imply that she was the first murdered victim from the Missing Children Incident.

Functionality
In Help Wanted, she has technology similar to the funtime animatronics, although her mechanical inside parts are not seen, and she has a beak that can pop open immediately like most funtime animatronics at the push of two buttons.
