Supporting and Protagonist
Unlike the supporting role who acts as a helper, playing a complementary role, the protagonist is the one who has a main role or function.
In the performing arts, for example, the protagonist is the
central character of the narrative. The supporting characters are all the other characters that are part of the story, but they are not targets of the central focus of the plot.
