A character of mine that I haven't uploaded yet, Spooks (Or Terren is his other nickname), is based off of a cat toy I got at a fair once.
For example, characters based on toys, or fursuits, or really any personal object.
I'll start, this is Ivy!
She is a furby based on a real one I own!
This is not a recent image, she now has one brown eye IRL.
lunation (and her assistant matryoshka) are both irl things i got at a convention in like ... 2014 or 2015? lunation is a plush and matryoshka was a kil 3d printed figure ! matryoshka actually sits on my laptop but i’m on the bus rn so i can’t add a pic D:
I would have to try and figure out where a photo is because she's packed away in storage, but Fio here was originally based on a plush cow I've had forever, named (drum roll please) Cow!
They are still in the works but I have a character based off a badly translated sheriff badge I have.
I'm not sure whether this counts but it's like FellowPigeon's example ¯\_(ツ)_/¯
I came up with the idea for Nev (seal who's a security guard) because the spray paint I'd got for college had a security seal on it and my brain immediately thought security guard seal.
I based this boy off a phone case I had in 9th grade. I created him so I could have a cute matchy-matchy chibi boi to tuck into the case, but I turned out liking him for more than just his aesthetic. He actually got me back into making OCs and world-building whoops
This is the one!! (In the spoiler box!!)
(edit) god that image looks bad on the teal site theme ewwww but y'all get the idea
This is Lechuguino!! Its based on a... strange round cushion I have and love ;v;
So I made it a guardian of dreams sort of...
