Dexter Morgan was born in blood, witnessing the brutal murder of his mother at the age of three.

Recognizing this darkness, Dexter's adoptive father, Harry Morgan, a Miami police officer, taught him to channel his urges into a more "constructive" outlet: targeting other killers who have escaped justice. This became known as the "Code of Harry," a strict set of rules to help Dexter control his urges and avoid getting caught.By day, Dexter leads a seemingly normal life as a blood spatter analyst for Miami Metro Police Department, a role that provides him with both cover and access to potential targets. His expertise in blood patterns is unmatched, making him an invaluable member of the forensic team. However, by night, Dexter hunts down those who have slipped through the cracks of the justice system, delivering his own brand of lethal justice.Despite his cold and calculating nature, Dexter struggles with his emotions and relationships. He deeply cares for his adoptive sister, Debra, and tries to maintain a semblance of normalcy with his son, Harrison. Throughout the series, Dexter grapples with his identity, questioning whether he is capable of genuine human connection or if he is doomed to be a monster forever.
