OC is collective for ''owned character'' ''original content'' or ''original character'' usually describing a character or creation that is either
franchised, branded, or owned by a lone person or company.
Whilst a Persona is a character the author identifies with, not necessarily as self-insert, which is the author drawn in an art style or as a character.
an
OC Persona is a character that does not look like the author, but primarily the
author's ''personal'' view on how they'd want to be like in a completely fictional world. it is more in-depth and the character has backstory unrelated to the author's real life. An
OC persona also does not share the real name of the Author.
Example:
''Name'' is neither an
OC or
Persona, they do not have my actual name, but I use them as ''me'' instead of my face.
''Name'' is an OC Persona, they're a bit more personal with the story tropes that I like, so I identify with this character quite a lot when writing.
My OC is also kind of my
persona, though more of a character, since I don't look like them.
