Sherlock Holmes, the famous consulting detective created by Sir Arthur Conan Doyle, is renowned for his intellectual prowess and remarkable powers of observation, deduction, and forensic science. Holmes is known for his cold and aloof demeanor, logical thinking, and preference for reason over emotion. His primary dislikes include the uselessness of emotion and general incompetence, often showing a lack of patience with those he deems foolish. Holmes has a complex relationship with his friend and biographer, Dr. John Watson, who provides the emotional counterbalance to Holmes's cerebral existence. His arch-enemy is the master criminal, Professor Moriarty.
