gods i have a ton of OCs ive projected onto in some way - none in the comic im posting atm, theyre personified religions and that would be weird, but a lot of older characters definitely!
my oldest OC minda used to just be a carbon copy, mary sue version of me for the Doctor Who universe. she then changed to a generic carbon copy mary sue version of me, but now she's even less that which is good! here she is!
a bunch of OCs (including minda, but also others) i have are lgbtqa+ or have fashion styles id like to wear too, so those guys have a bit of my personal experience as well. i think it's partly to do with empathy and wanting to see people like you in the media, but for me it could mayyyybe also be the trauma lmao. a LOT more of my characters have an abusive parent than is probably healthy
