As in...original characters in a story I've written? I've got a ton of them. In my most recent story, five characters are Nindros, Avriel, Kyrian, Arthax, and Brightbranch. It's fantasy, which is probably obvious, although I've written some non-fantasy stories.
TPBM has rewritten the ending to a book they read because they didn't like how the author ended it.
