- Main article: Dexter Morgan
Dexter Morgan is the lead and title character of the Dexter Book Series written by Jeff Lindsay. Dexter is a charming yet sophisticated forensic blood-spatter analyst who just so happens to be a Serial killer.
Dexter is the foster-child of Harry Morgan and Doris Morgan, as well as the foster-brother of Deborah Morgan. He is married to Rita Morgan, has a biological daughter named Lily Anne Morgan and two step-children Cody and Astor Bennett.
The character and novel Darkly Dreaming Dexter inspired the SHOWTIME series DEXTER which follows the events of Darkly Dreaming Dexter throughout Season One with several key differences (notably Debra Morgan does not find out about Dexter's true life but Deborah Morgan does, Maria LaGuerta is alive while her counterpart Midgia LaGuerta is not and Dexter's biological brother, Brian Moser dies at the end of the season while Brian Moser survives and has returned in at least two novels to date). Season Two onward diverges itself from the Novel's timeline and makes the series a separate universe altogether with new characters, events, and deaths that have not occurred in the novels (thus far).
Dexter Morgan as far as difference in character is far more "human" in the TV series, starting to discover the importance of love for friends and family throughout midway into Season One and then each season after this tests his emotional state in one way or the other. Season Two tests his ability to accept his Dark Passenger after killing his brother Brian Moser while also dealing with the relationship issues with his girlfriend Rita Bennett, Season Three sees Dexter opting for marriage while also finding out he's a father-to-be (when Rita becomes pregnant) in addition to finding a friend that he shows the "true" him to but unfortunately finds that his friend merely used him for personal gain, Season Four has Dexter as a father and husband struggling to figure out how to survive for years to come and seeks assistance from Arthur Mitchell, a serial-killer family man who has murdered for over 30 years. Season Five provides Dexter the loss of his beloved Rita, with her dying at the end of the previous season he struggles to cope with this loss by first killing people but then deciding to aide a woman named Lumen Pierce who he becomes romantically involved with and in turn finally moves passed the grief and guilt of Rita's death. Season Six throws Dexter into religion and his relationship with just his son Harrison, also gaining a friend by the name of Brother Sam then losing him shortly thereafter while also gaining back his brother, Brian Moser.
When Dexter reaches a sexually mature age, he realizes that he is uninterested in sex and needs instruction by his father on how to act with women.
When Dexter was 18, Harry fell ill of coronary artery disease and was confined to a hospital where Harry spots a nurse who kills people by overdosing them on morphine. Harry gives Dexter his permission to kill her. However, Harry realizes he made a mistake when Dexter returns.
Dexter Morgan is the title character of each of the books in the series and as such has been the main focus of each novel, mostly told from his perspective.
Near the end of the first book Brian and Dexter meet in a storage container similar to the one they were held in as children, and Brian recounts what happened. He says that one of the bodies they were surrounded by could have been their father for all they knew. Deborah is awake when Dexter arrives at the cargo container, and she learns of Dexter's hobby as a serial killer. After the death of Detective LaGuerta, Deborah begins to accept Dexter.
During Dearly Devoted Dexter, Dexter is forced to 'wear' his disguise all the time after finding out that Sergeant Doakes is following him, trying to catch him in the act of killing somebody. In desperation, Dexter tries to find something out about Doakes that might be useful in getting Doakes off his tail. However, he finds out very little.
Dexter realizes that Doakes and Kyle Chutsky know each other after Doakes has Captain Matthews call in help from Washington when a still-alive and heavily-dismembered body is found. Dexter learns from Deborah and Chutsky that Doakes served in a black-ops mission in El Salvador, and he also learns about Dr. Danco, the man responsible for the mutilated body. However, Chutsky himself is taken and Deborah pleads with Dexter to find him.
Not long after, Dr. Danco sends Deborah Chutsky's finger with the ring still attached. Dexter keeps the ring to give back to Deborah, but Rita finds it and believes that Dexter was meaning to propose to her.
Dexter, Deborah and Doakes work together to try to find other members of the El Salvador unit. During a chase through Miami, Dr. Danco runs Dexter and Deborah off the road, and it is left to Dexter to find Dr. Danco and Chutsky. Dexter and Doakes set up a trap to lure the doctor. The trap works too well - Dr. Danco takes Doakes. Dexter traces Doakes' cell phone to an alligator farm where he finds Chutsky and helps him escape, but Dr. Danco escapes with Doakes. Deborah and Chutsky ask for Dexter's aid in finding Dr. Danco once more, however Dexter himself is captured by Dr. Danco and it is only due to the timely arrival of Deborah and Chutsky that saves him.
In Dexter in the Dark, the third novel of the series, it is revealed through third person narrative of an entity referred to as "IT" that the Dark Passenger is an independent agent inhabiting Dexter, rather than a deviant psychological construction. Later, Dexter realizes the Dark Passenger is related to Moloch, a Middle Eastern deity worshiped in Biblical times. The Dark Passenger is one of Moloch's many offspring; Moloch had many children (formed through human sacrifice), and learned to share its knowledge with them. Eventually, there were too many, and Moloch killed the majority; however, some of them escaped into the world. In the novel, Dexter learns of the Dark Passenger's true nature when it briefly "leaves" him, frightening him into researching possible reasons for its existence. Dexter comes to accept his role as stepfather to both children very seriously in Dexter in the Dark, albeit in his typical fashion. For example, while on a stakeout, he begins to wonder if Cody had brushed his teeth before bed and if Astor had set out her Easter dress for picture day at her school. These thoughts distract him from hunting an intended victim, which thoroughly annoys him.
Dexter by Design is the fourth book in Jeff Lindsay's series about Dexter Morgan, a Miami blood spatter analyst and vigilante serial killer. Here, Lindsay deviates from the supernatural subtext of the previous book, Dexter in the Dark, and focuses on the psychological suspense. The book opens in Paris, with Dexter and Rita on their honeymoon. There, while visiting an art gallery, Dexter and Rita are introduced to the concept of body parts being used as art by an avant-garde performance piece called "Jennifer's Leg" in which the artist amputates her own limb. When they return to Miami, Dexter crosses paths with two new enemies; a suspicious homicide detective, and a new serial killer in town targeting tourists.
In Dexter is Delicious, Dexter finally decides to give up his dark hobby after witnessing the birth of his daughter Lily Anne. He believes that for the first time in his life he is feeling genuine emotion.
During the novel, Dexter is reacquainted with his brother Brian, who knows about Dexter's child. Dexter struggles with the burden of feeling emotions while attempting to give up his serial killing life. At one point, Dexter indulges himself after getting angry, but he immediately vows not to do it again.
At the end of the novel, Dexter sets out to kill Bobby Acosta, the cannibal son of a city commissioner who gets away with murder and cannibalism, after Deborah realizes that Bobby's father will simply pay for the entire thing to disappear.
In this Novel Dexter is unwitting spotted while performing his Hobby. This person soon begins to torment Dexter while also begining their own killing spree. Dexter finds himself in a game of Cat and Mouse, as Dexter tries to find his tormentors Identity, because they do know his.

- Author Jeff Lindsay in talking about Double Dexter refers to Dexter as a man you shouldn't be seduced by. ""Some believe that Dexter cares about justice. Dexter doesn't care about justice, he cares about killing,""...this differentiates the serial killer in the TV series that appears to have some sense of justice (such as his actions in Season Two) from the one in the novels, making him more inhuman.
