These terms and links will help you answer.
From Wikipedia:
A protagonist is a term used to refer to a figure or figures in literature whose intentions are the primary focus of a story. Classically protagonists are derived from good will, however, this does not always have to be true. Protagonists cannot exist in a story without opposition from a figure or figures called antagonist(s).
Topic 2:
Who is the antagonist in “Stranger Than Fiction?”
These terms and links will help you answer.
From Wikipedia:
The main character is often faced with a "foil", a character known as the antagonist who most often represents obstacles that the protagonist must overcome. As with protagonists, there may be more than one antagonist in a story. (Note that the term antagonist in this context is much more recent than the term protagonist, and rests on the same misconception as the use of protagonist to mean proponent. See below.)Sometimes, a work will initially highlight a particular character, as though they were the protagonist, and then unexpectedly dispose of that character as a dramatic device. Such a character is called a false protagonist.
