Ivan Isaacs

Priest (or Ivan Isaacs in the graphic novel from which the movie is very loosely based.) is the protagonist of both the movie Priest and the graphic novel. As a faithful follower of God, and being highly skilled in combat, he decides to hunt down the vampires who kidnapped his niece, Lucy. However, in order to do this, he has to break the vows he made to give up vampire hunting. He joined the church after the last Vampire war and the Veteran Warrior Priest is living in one of the Church's cities.
