Answer:
In the story "The Most Dangerous Game." General Zaroff is the character foil for Rainsford.
Step-by-step explanation:
A foil character is made to contrast and highlights the main character, by being different from them or by being the same but having a different point of view.
Rainsford was a hunter and he enjoyed hunting as anything else, but when he starts to interact with Zaroff his role changes from the hunter to the hunted.
