If you’re talking about any story, then it would usually be the protagonist (the hero, the main character, and/or the humanitarian). On rare occasions the story will take place with a character that’s the antagonist (the bad guy, and usually has a lot of trauma that caused them to be the bad guy.) when the antagonist is the main character in a story it’s usually to show us the backstory of this person and what led up to them being bad.
