My first OC and my newest mysteriously have the same name. Mariah.
I don't have any old drawings on hand of the first Mariah, but if I drew her today, this is what she'd look like:
Also, the old Mariah was a bully. Not sure how I managed to keep her in existence into middle school.
The new Mariah is much different. Not only is she nicer, she's also not human.
And while the old one was a school girl, the new one is an idol (though the only concept art I currently have of her is in her normal clothes)
