Angelo "Angel" Juan Marcos Batista (; Spanish ) is a fictional character in the Showtime television series Dexter and the novels by Jeff Lindsay upon which it is based. He is portrayed in the television series by David Zayas. Batista spends much of the series as a Sergeant before being promoted to Lieutenant in the final season. Character biography Angelo "Angel" Juan Marcos Batista is a Detective in Miami Metro Police Department's Homicide Division. He works closely with Dexter Morgan (Michael C. Hall) during cases, often teaming up with him for his expert advice on serial killers. He also functions as friend and mentor to Detective Debra Morgan (Jennifer Carpenter), Dexter's foster sister. Angel is a friendly, good natured man who provides a sense of humanity and compassion in Dexter's life. While he is prone to making rash decisions and acting on emotion, he does not harbor any resentment for even the worst fate hands to him and is shown to care deeply for those who work around him. He is also well known for his trademark fedora hat which he is almost never seen without. Due to his position as a divorced, lonely police officer, he considers himself a cliché. Season one When Angel arrives on the scene of a foot chase called in by James Doakes (Erik King), he finds the suspect dead. When first questioned by Internal Affairs, Batista lies for Doakes, saying the other man shot first. However, he later tells the truth, saying that he made a promise to his father that he would always be an honest man. When Batista cheats on his wife, he tells his wife about the indiscretion, which leads to their separation (something he tries to keep hidden from everyone). One night at a club Batista sees a woman with a prosthetic hand, the nails painted in the same manner as the victims of the Ice Truck Killer, a serial killer who preys on prostitutes. He investigates and finds out that the woman had a customer with an amputee fetish. In an attempt to chase the lead, he talks with prosthetic technician Rudy Cooper (Christian Camargo) about patients he may have that have the same fetish. Cooper — who is none other than the Ice Truck Killer — then stabs Batista. While recovering, Batista agrees to a divorce with his wife. He also helps to uncover Cooper's true identity by
