ANTAGONIST: An opponent or adversary opposing action of another
PROTAGONIST: Principal character, supporter of a cause, from Greek = First Actor
Recently, whilst working on my WIP, I examined principal character interaction to solve some issues. Something interesting revealed itself. Let me explain (keeping names aside so as not to reveal plot spoilers!). There is an antagonist, one of my hero’s nemeses. He opposes the hero’s actions and becomes an untrustworthy adversary. However, he is opposing the hero because of something he believes in, a ‘cause’ (see ‘Protagonist’ above). Likewise I have a protagonist who, at the beginning of my story, opposes most things and people he comes across, including long-standing friends (see ‘Antagonist’ above).
