It has to be Ivan, General Zaroff's assistant. Rainsford and Zaroff are the protagonist and antagonist, respectively. He is a Russian Cossack like Zaroff, but he's very large and brutal. He seems to enjoy killing, and Zaroff uses Ivan to kill if anyone decides not to be hunted.
its whitney. i know the other guys said ivan, but i took a course last year and we read that story. it is whitney, he is in the beginning simply to eventuall show how the main character rainsford changed
read it over and you'll see
Ivan definetly has to be the subordinate character. Rainsford has no other characters on his side. We had to read that in my english class too; good story.
