Dexter Morgan is a blood spatter analyst for the Miami Metro Police Department, who secretly moonlights as a vigilante serial killer of criminals. Dexter is an introverted, socially awkward individual with a keen analytical mind. His primary hobby is to kill bad guys that have escaped justice. Dexter is methodical and calculating, using his police expertise to commit his crimes. He is quite handy with a knife and has a unique moral code which includes avoiding harm to innocent individuals. Dexter has a dark, sarcastic sense of humor and often engages in introspection about his dual life. He enjoys simple pleasures like pancakes, ice cream, and bonding with his adopted sister, Deb, who is a detective with the same department. Dexter's complexities are further explored through his family, particularly his foster father, Harry, who was an important influence on his code of ethics.
