Several figures fill this role. First, the role is taken on by the big game – the lion in particular – who stand in the way of Macomber proving his manliness on the hunt. But it quickly becomes clear that Macomber has bigger problems on the home front, with a nagging, hostile wife and a hunting guide who has his eyes on Margot. In the end, Margot and Wilson seem like the clear enemies of the story. After all, Macomber says outright that he hates Wilson. Oh, and there's that whole to-do in which Margot shoots Macomber. You don't get much more antagonistic than that.
