Yeah, but while he is possessed Mal takes the screen time and drives the plot, and since Chris is obviously the antagonist due to him creating and giving the challenges, Mal is definitely the main character, pretty much the whole series follows him on his way to win the million.

Mike's role here is to be Mal's most dangerous enemy and challenge, and since he technically doesn't interac with the other characters due to being imprisoned by Mal on his mind along his other personalities, he fits the role is being the antagonist of Mal's evil journey.
