Il Dottore is a very powerful demon. He is a very serious individual, but that only enforces is cocky and confident attitude. He is intelligent, and uncaring about most things that do not regard his work. He is a man of logic and intellect, and despite his emotional knowledge, he tends to disregard the feelings of others, and is apathetic to most. He holds little regard for those who worship and sacrifice, but can be summoned if someone chooses to. He is fairly easy to irritate.
