There aren't many differences to be seen on this model of Chica that isn't on the original, but what is notable is the endoskeleton is completely different from the original, with thicker wrists. Despite all promotional material and artwork depicting Liberty Chica's cupcake as on fire, in game it appears to only be slightly glowing orange. However, the springlocks in the suit suddenly malfunction (possibly due to the rain water seeping into the building), causing the locks to become loose, resulting in his brutal death. Scorching Chica's design is nearly identical to Chica, except she is now completely made of a scorching magma-like material, with fire spewing out of her body. As seen in FNaF 2 minigames, after five children had been killed by William Afton, their souls are put into the animatronics by The Marionette, including Chica.

Neon Chica's model is identical to her original counterpart, only colored in neon black with a slight purple outline that illuminates in the lighting within the level.She is seen to be badly damaged, having many tears in her cloak, a multiple scratches on her body and beak and a large gaping hole showing her endoskeleton. Her hair is swept over from the top of her head and held in place with a delicate pink bow, while her big purple eyes shine full of joy. While Chica looks very similar to her original version in the main FNaF games, she is now made of a shiny, glossy plastic, and her overall body has scratches and stains on it. These are Roman Numerals, and they translate to “July 4th, 1776,” the day the Declaration of Independence was approved and adopted by the Second Continental Congress. It has pink-frosting with two large yellow eyes, a yellow-striped birthday candle with a vinyl candle-light, buck teeth, no wrapper, and, like other animatronics (except Foxy and Golden Freddy), has black eyelids.

In the Five Nights at Freddy's 1 section, Chica will make her way to the player's office along with Freddy, Bonnie and Foxy, just like the original game in which she debuted. If the instructions aren't followed properly, like throwing away the pizza in her suit in the wrong place, failing to catch the cupcake quickly enough, or eating the pizza before you're told, Chica will jumpscare the player. As shown in FNaF 3 minigames, William Afton then found out about the trapped souls inside the animatronics, and decides to come back to the place and destroy them one by one. Due to the event getting delayed by multiple days, Illumix rewarded players with a free 3D avatar icon of Little Red Chica for their patience.Once the player enters the kitchen, Chica will appear and approach the pizza placed in front of the player. When she crosses past the office, she also might turn and enter the office instead of walking to the corner of the hallway. written in a bubbly, yellow font with a purple outline, also containing pink, blue, and yellow confetti-like triangles covering the rest of her bib. Little Red Chica looks identical to Chica however is now gray in coloration and is wearing a red cloak. To avoid being jumpscared, the player must locate her static, look away while she haywires, and shock her when she charges and materializes.
