Well, I've got a fursona and a "true"sona:
Katja, my fursona
Are they an absolutely overpowered wish-fulfillment character? God yeah. Is that literally the point? Also yes. You can check out my FA for a bunch more art of them, though a lot of it is NSFW. ,,, But if anyone wants to hear me yell about them on here, well, let me know!
Eva, my "true"sona
They're kinda like if you took me and then changed a bunch of inconsequential variables in my history. But also if they were a foxdeer. They're as "me" as I can get without making a "true"sona that doxes me, more or less.
