I'll appear in another novel, perhaps (8)
I believe the answer is:
antihero
I'm afraid I can't explain this answer.
Can you help me to learn more?
(Other definitions for antihero that I've seen before include "baddie" , "Principal character without virtue" , "Less than admirable character" , "Central character lacking traditional courageous attributes" , "Winston Smith in Orwell's 1984, for example" .)
