Iconic. FNAF oc.
I have one other, but she doesn’t have a toyhouse + wasnt used as an oc until two years ago
Or the oldest OC that you have.
I’ll start with a classic - Spike. I’ve had him since I was four. Most of his art is digital & requires uploading to his page. (Just a word of warning lol once you look at his profile you’ll be slapped with lots of old art)
Out of the OC I have posted, I think Ophiel is the oldest. I believe I made him about 12-13 years ago now.
If not him, it would be Aternus. I made him right about the same time and it has been so long now I don't remember exactly who came first.
Can't remember the exact age I made her, but Zacharia is based on an OC I had in elementary school 💖 the brighter pink palette in her gallery is based off her original colour scheme
oh gosh, out of everyone ive posted? piss cat, currently. (almost a year old. happy early birthday!) though i have some wayyy older ocs that i dont use anymore. the oldest one in my gallery is this one-off amongus oc. might actually use him soon 
I don't know what's my first proper oc but here's all of them I made before I turned 13:
- Pips Pups, a growlith I made up when I was 10. He's on Pokemon Go and evolved, still love him.
- Disney Yoshis, made them when I was 5. The drawing of them are framed at my grandmas place, likely lost.
- A werewolf girl that wears a pink dress, I made her when I was 7 or 8. Lost the drawing.
- Max, one of my first humanoid OCs I made when I was 11. He's a 11 year old punk with a blond Mohawk and calls him mum fat, oh my god what a rebel!!!!
- Sarah, a fat 4 year old girl with long black hair, didn't know how to draw hair so she looked like she has a mullet. Don't know where the drawings are but likely lost.
- A shiny staryu I used to draw alot when I was 5 or 6. Technically an oc.
- Naomi, had since her since she was 12. She's a yandere and couldn't decide who can be her love interest until recently. She has a ToyHouse profile IC.
- Leon, Naomi's OG love interest. Made him when I was 12.
- Gregory, had him since I was 12 and looks very similar to Gregory from Security breach.
- Diana, a woman with a deformed face had her since I was 12.
- Phonix. Had her since I was 12.
- Snowball, my very first adopted character when I snuck on discord underage. Forgot who made him but all I remember is that he's a skeleton.
Him, he's the only oc I have that I made before I turned 18 and for good reason because all of the ocs I made as a kid just weren't good. Liev was the oc I happened to make for the first long term rp I ever did which gave me time to realize he was poorly written and that I needed to improve my writing skills. He's mainly the same as his original version just with more realism and depth to him now, before he was a boring edgelord.
This baby is my oldest OC... at least so far as I can remember. Made her to do warrior rps with my friends on wildfire. It was so sad when that site went down. We moved to google docs and I had so many stories and lore and pictures, but it was all on my highschool email and after I graduated they wiped the account so I don't have any of it anymore and I'm too heartbroken to try writing it all out again. Maybe someday.
