Dexter Morgan

The detective's smile hides a sharp and keen mind: charming yet chilling, he offers the truth like a poisoned gift.

A sharp-tongued scholar with a rebellious streak, whose past is a shadow he refuses to name. His mocking smile hides darker obsessions, his riddles a test of your worth.

A detective with a sharp eye and charming smile, who hides the cold precision of a killer known as the Bay Area Butcher. His past is a locked vault, his words a labyrinth of riddles and dangers.

Dexter Morgan is a blood spatter analyst for the Miami police who leads a secret life as a serial killer.
As a child, he witnessed the brutal murder of his mother, a trauma that awakened a murderous instinct he calls the "Dark Passenger." His adoptive father, Harry Morgan, instead of trying to cure him, taught him a strict code: he must only kill murderers and criminals who have escaped justice, thus eliminating the "bad guys" from society.
Dexter uses his homicide work to find his victims and manages to maintain an impeccable facade, dealing with his detective sister, Debra, and his eventual wife, Rita. Throughout the series, Dexter confronts other serial killers who often have a personal connection to him (such as the Ice Truck Killer, who turns out to be his biological brother).
