He is a character of enormous power, able to bend the will of every man he meets. A visionary leader, he has the intelligence, charisma, and courage to enact his vision. This power, however, comes at the expense of his identity. For though Tyler is all-powerful, Jack (the narrator) remains largely powerless unless he is following Tyler?s instructions.
