So here we have our second OC, entered by @DreamDragon84. Thanks for submitting your OC!

Name: Greta

This is a cool name.

Nickname: N/A, just Greta

Honestly, I also can't think of a nickname, so yeah.

Animal/Creature: Anglo-Nubian Goat

Specific. Very specific. Nice. I barely see goat animatronics, and even less such specific Anglo-Nubian goat! Searched them up, they're pretty cute.

Material: Cloth-like, metal (like the original animatronics)

Reading the rest of the form, this makes sense if she was made as a replacement.

Accessories: N/A

None is fine, but I imagine her in a cute collar with a bell on it.

Appearance: Slightly taller (and heavier) than Chica. Has a tangerine orange head with a long sepia nose plus a black triangle mouth and black thickish eyebrows. Emerald-green eyes. She has taupe tendril ears, which really give her away as an Anglo-Nubian goat. Her calves are a light grey (like a dusty Sister Location animatronic) and she has pecan brown hooves. Other than that, she has the body shape of Chica with brick-red torso, shoulders, upper arms, and hands; crimson thighs and kneecaps; and merlot forearms, underbelly, and hips.

This is one of those bios where people actually put effort into. Pecan brown? Merlot? Many people would use brown and reddish-brown instead of that. The colors specificities are great.
Wait... She's heavier than Chica? But Chica is as fat as a plum!
The rest of the bio makes sense, having it be similar to another female animatronic, them being from the same place and all.

Possessed: Yes

Nothing to say here.

Gender of Animatronic: Female

Okay.

Gender of Possessing Ghost: Female

Nice.

Name of Possessing Ghost: Julianna (Julie) Carter Ramirez

Nice name!

Preferred Gender: Female

It makes sense, in my opinion.

Sexuality: Pansexual (doesn't even care at this point)

dOeSn'T eVeN cArE aT tHiS pOiNt. I'm sorry I had to do that, the way you worded that made me laugh. No offense meant if anything seems offensive.

Preferred Pronouns: She/Her

Like I said, it makes sense.

Age of Animatronic: (I don't really know, I use her for roleplay and I don't exactly know when those take place, but I'll just say) 15 years

Many role play characters have their family heritage and age vary for different role plays, I have characters like that too. And 15 years? If the original animatronics were made in... *lots of weird calculating later* You know what? That's fine.

Age of Possessing Ghost: 16

For some reason, I get annoyed as heck when someone has their FNAF OC be possessed by a teenager or older child. THEY. ARE. OLD ENOUGH. NOT. TO DIE. Eh, you can keep it that way.

Personality: Greta is calm, blunt, and quiet. She is also pretty smart and observant, and attempts to be friendly. It never seems to work however, as most of them just ignore her.

I mean, the personality fits her, but the quiet kind of ruins the friendly attempt, or the opposite. In my opinion, quiet people don't try to make friends that much. Maybe make it a bit more specific or don't.

Strengths: Book-smart, cautious

Okay, maybe the cautious would've been helpful during her death.

Weaknesses: Passive, Submissive

Nothing to say, except for... nevermind, you can keep it the way it is.

Likes: Eating food, trying to make friends, collecting humans to give to the other animatronics, sulking in the Backstage, messing with the night guards

Eating food. She's more similar to Chica than ever! The making friends I sort of discussed earlier. COLLECTING HUMANS?! *epic sputtering* NOPE! I'm sorry, this makes sense given the others kill them and all so... Okay, she likes sulking in the backstage. That, for some reason, also makes me laugh. The messing with the night guards also makes sense, so that's that.

Dislikes: Being ignored (it happens way to often), night guards

Aw, she gets ignored? I know it said that earlier, but this is kinda sad. And the night guards? Nothing to say.

Date of Creation: (I don't know specifics but) About a year after the original animatronics' creation

Aight, that's fine.

Company: Afton Robotics

Of course.

System: Fazbear Entertainment

Yup.

Cause of Death: Julie was stuffed inside the animatronic (Greta)

Like all of them.

Status: In the Backstage, getting dusty and rusty, looking "lifeless"

dUsTy MuStY cRuStY rUsTy... I had to.

Performs At: N/A, would be at Freddy Fazbear's Pizzeria (first game location) but was never used

Reading the backstory, this makes sense but the backstory makes me mad. You'll see why.

Bandmates: N/A, doesn't perform

Nothing to say hereeeee.

Relationship With Bandmates: N/A (if you want to count the original animatronics, she's friends with Chica, but ignores everyone else)

Yup. Chica is her only friend. *Make Your Move starts playing* tHeSe HeLpLeSs RoBoTs ArE mY oNlY fRiEnDs.

Purpose: Was going to be an addition to Freddy, Foxy, Bonnie, and Chica, but is now a backup animatronic if Chica (or any animatronic) couldn't be repaired in time for the day.

Okay, that's good.

Fun Facts: She stares at the cameras at night

Doesn't everyone?

Possessed Ghost's Backstory: Julie went into Freddy Fazbear's Pizzeria to celebrate her little sister, Jenna, for her birthday. The curious teen wandered into the Backstage area right before closing time. It was her first time eating at Freddy's and she was interested in the animatronics. Normal pizzerias don't have robots in them, and she had the guts to ask an employee to show her the backstage. The worker, though confused, let her in, and she immediately took notice of the disregarded animatronic in the back. She empathized with the goat, feeling mishmashed and alone. Suddenly, as she tried to leave the Backstage, she was stuffed into Greta. This made the goat's black pupil's gain a green iris to match the girl's eyes.

This is a decent backstory, teens are curious kids and like exploring. My only question is who stuffed Julie into Grenda?

Backstory: The workers and designers of the animatronics at Fazbear Entertainment came up with the idea of a goat animatronic addition to Freddy, Bonnie, Chica, and Foxy. The head was prototyped and special features like hooves were created. The idea, along with the animatronic, was scrapped soon after since the designers didn't like the idea of an orange goat in a pizzeria.

Animatronic racism.

 After a couple weeks, William Afton returned to the metal goat head+hooves, and used a discarded Chica model and spare Foxy paint to finish Greta in secret. She never made a debut in Freddy Fazbear's Pizzeria, though William made up an excuse to keep her around, telling himself (and any employee that asks about the red Chica-shaped heap in the Backstage) that it's an emergency animatronic if Chica (or any animatronic for that matter) couldn't be repaired in time for the day. 

One of the only good things Afton ever did (for those who believe in the Afton is Purple Guy and the murderer).

Fortunately for the pizzeria that never happened. Greta has stayed in the Backstage area of the pizzeria all of her days, a lifeless heap of metal. After a few years, Julie possessed Greta after being stuffed inside. Greta now loves to roam around the pizzeria when it's closed but avoids people at all costs (unless they start looking at her, in which case she will go towards them, but get easily distracted). She spends a lot of time with Chica at night, especially in the kitchen.

Alright, so she's like the others now that she's possessed. That's nice.

Overall, this OC gets an overall rating of 8.9/10. Good job, and thank you for submitting your OC, DreamDragon84!
