Detective Sergeant Ángel Juan Marcos Batista (usually though in Spanish ) is a fictional character in the Showtime television series Dexter and the novels by Jeff Lindsay upon which it is based. In the television series he is portrayed by David Zayas. Angel is a Detective in Miami Metro Police Department's Homicide Division. Batista works closely with Dexter Morgan during cases, often teaming up with him for his expert advice on serial killers, and considers himself Dexter's best friend. Batista, while unable to share Dexter's fascination with blood, appreciates the art of murder. In the novel series, Batista is not a detective, but a forensic officer who works alongside Dexter. He is also referred by himself and others as "Angel no-relation" in reference to former Cuban dictator Fulgencio Batista. Batista is basically good-natured, with a dry sense of humor.
