Sona

A representation of yourself as a human character, typically with a reference of a sort. Can be either an idealized version (ex funny, happy and charismatic) or realistic to yourself (ex a slob, depressed and socially awkward)

A subterm for this word is fursona, which is more specific for an anthro character.

Friend: Hey could I see your sona?
Me: Sure, but she's really bad.
