Golden Freddy (Cassidy)

1. Teleportation and Spectral Appearance
   Barrier-free infiltration: Golden Freddy can instantly appear and disappear inside the security guard's office, completely ignoring whether the armored doors are locked or the ventilation ducts are blocked.
   Holographic projection: It doesn't need to "walk" to move around. It can manifest directly sitting on the office floor or as a gigantic disembodied floating head in the central hallway (as seen in FNAF 2).
2. Manipulation of Reality and Hallucinations
   Psychological Attack: Its mere presence is capable of distorting the player's perception of the environment. It causes flickering lights, static on the cameras, and sudden visions on the screen with the phrase "IT'S ME," accompanied by images of the original animatronics' faces with human eyes.
   Environment Lockdown: In the first game, if he appears in the office and the player doesn't act quickly, Golden Freddy can force the camera monitor to shut down suddenly, forcing the player to face him head-on.

Unlike Freddy, Bonnie, Chica, and Foxy, Fredbear's suit was empty, lacking a complete or functional endoskeleton, and stored in a basement or warehouse. Because of this, Cassidy couldn't walk freely around the pizzeria.
This forced her soul to manifest as a spectral projection or hallucination capable of teleporting, passing through walls, and changing shape (like the giant floating head in FNAF 2). Over the years, Cassidy stalked the security guards at the location (including Mike Schmidt) because she mistook them for her killer, instantly killing them if they stared at her through a collapse of reality ("Jumpscare").

Cassidy was an ordinary girl who attended Freddy Fazbear's Pizza. On June 26, 1985, she, along with four other children (Gabriel, Jeremy, Susie, and Fritz), was lured into a back room by William Afton, who was wearing the Spring Bonnie costume.
Afton murdered her, making her one of the victims of the infamous "Missing Children Incident." Afterward, The Puppet (Charlotte Emily) guided the children's souls to possess the animatronics, granting them a second life and a chance for revenge. While the other four possessed the main animatronics, Cassidy's soul was drawn into Fredbear's stored and unused suit (the original golden bear model), transforming her into Golden Freddy.

Hair: She has long, dark brown hair. It is styled in two high pigtails on either side of her head, secured with yellow/gold ribbons or ties. She also has straight bangs covering her forehead and some long strands framing her face.
Face and Expression: His expression is one of deep anger, resentment, and bitterness.
His eyes are completely shadowed, showing a thick black outline and small, empty, white pupils (a classic feature in fan art to denote possession or a ghostly state).
Her mouth is slightly open, showing her teeth in a gesture of frustration or contained fury.
A strong reddish blush is noticeable on her cheeks and nose, which in this context highlights the intensity of her anger.
Clothing
Top: She wears a long-sleeved, textured turtleneck sweater with vertical stripes (ribbed knit). It is an ochre or gold color, clearly alluding to Golden Freddy's color.
Bottoms: Over the sweater, she wears a dark brown jumpsuit or sundress. She also wears opaque black tights.

Despite the monstrous rage he harbors for William Afton, Cassidy is not a purely evil being; he displays a markedly compassionate, curious, and protective side toward the other victims. This is revealed primarily in the Survival Logbook.
He is patient and seeks to help: In the book, Cassidy communicates through altered and enigmatic text with the soul of Crying Child (Afton's youngest son who died from Fredbear's bite).
Concerned about the trauma of others: Instead of attacking him, she asks gentle questions to help him remember his past, such as "Do you still talk to him?" (referring to the Fredbear plushie) or "Do you remember your name?". This shows that, before being completely consumed by UCN's revenge, Cassidy acted as a support for trapped souls who were more confused than she was.

. An immeasurable fury and resentment (The "Vengeful Spirit")
Cassidy's strongest characteristic is her anger. It is widely accepted in the community that she is "The One You Should Not Have Killed" in Ultimate Custom Night (UCN).
Cruel and merciless with her tormentor: While the other children's souls find rest and peace after the fire at Freddy Fazbear's Pizzeria Simulator, Cassidy refuses to leave. Her hatred for William Afton is so immense that she creates a personalized purgatory, or eternal torment, just to torture him again and again.
Obsessive: She prefers to keep her own soul bound to earthly suffering in order to ensure Afton pays for what he did, demonstrating endless stubbornness and a thirst for revenge. Even the character in Old Man Consequences has to ask her to "leave the devil with his demons" and rest for once, and she refuses.

Species: It is an anthropomorphic bear of robust and heavy build.
Main color: Its synthetic fur or coating is a dull mustard yellow or dirty gold. The entire surface is covered with dark stains, grease, dust, and burns that simulate extreme neglect.
Face: It has completely empty and dark eye sockets, giving it a blank and sinister appearance.
Its snout is a slightly lighter shade of yellow, topped by a small, shiny black nose.
In the lower jaw, some white, square, humanoid-looking teeth, typical of these animatronics, can be seen.
It has round ears on the top of its head; The character's left ear (right of the image) appears to have loose wires protruding from its base. Top Hat: He wears a small, dark purple top hat tilted to one side on the top of his head. Bow Tie: On his chest, he sports a large bow tie of the same dark purple/purple hue, which is slightly worn. Button: Just below the bow tie, in the center of his chest, is a single large black button. Torso: He has a huge opening on the left side of his stomach (right of the image) that reveals red and gray wires, as well as the internal metal structure. Limbs: The arms and legs show deep cuts and missing sections, especially at the shoulder, elbow, knee, and ankle joints, exposing the metal tubes and pistons of the endoskeleton.
Several loose colored cables (red, blue, yellow) protrude from the shoulders and elbows.
Hands and Feet: Its hands have thick, articulated fingers. The feet are large, heavy, and have three rounded toes, with textures that simulate wear from the ground.
