There is Dr. Who audio drama by Big Finish Productions featuring (I think) the 7th Doctor that involves a villain from an in-universe movie or novel suddenly coming to life. He starts off just being a villain in real life until he learns he's fictional and his entire traumatic backstory was written by an author at which point he decides to kill the author because he can't fathom how anyone could subject someone to such cruelty.
