Angelo "Angel" Juan Marcos Batista (/ˈeɪndʒəl/; Spanish [ˈaŋxel]) 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 (Dexter, New Blood, and Resurrection), and as the younger version of Batista by James Martinez (Original Sin). Batista spends much of the original series as a sergeant before being promoted to lieutenant in the final season.

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 portrayed as a friendly and good-natured man who brings a sense of humanity and compassion to the show. Despite his tendency to act impulsively and make decisions based on emotions, Angel does not hold grudges, even when faced with difficult circumstances. Rather, he is depicted as having a deep sense of care for his social environment, particularly his colleagues. Angel is also notable for his signature trilby hat, which he is rarely seen without. Being a divorced and lonely police officer, he views himself as a cliché.

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 asking for Cooper's prints to be compared to mental institution files.

After three months of being on his own, Batista turns to spiritual enlightenment to lessen his pain. He claims to be Dexter's best friend, much to Dexter's confusion, as he has never given Batista any reason to think so. However, Dexter eventually admits that Batista is the closest thing he has ever had to a real friend.

In season two, Batista and the rest of the department try their best to alleviate the grief from families of the Bay Harbor Butcher victims. He becomes especially involved in one case of a suspected murderer named Oscar Sota. When he talks to Sota's widow (Bertila Damas) in his office, he ends up having a heated and frustrating argument with her about what her husband was actually doing to be targeted by the Butcher. Feeling guilty, he goes to her house and offers her a sincere apology. She begins to trust Batista, and offers him more details on the case.

He eventually takes an interest in Dexter's on-off lover Lila Tournay (Jaime Murray), and asks her out after she and Dexter break up. Unbeknownst to Batista, however, Lila is only using him to get close to Dexter. To that end, she takes Rohypnol after having rough sex with Batista, and then accuses him of date rape. Batista is terrified of being convicted, as it will ruin his career and his life. After Dexter kills Lila, the charges are dropped, much to Batista's relief. During an awkward but heartfelt conversation, Dexter tells Batista that if he were "normal," he would want to be a man like him.
