Cast and characters

Main

* Alan Tudyk as "Harry Vanderspeigle", the titular alien with an unpronounceable birth name who has crash-landed in Patience, Colorado, killed the real Dr. Harry Vanderspeigle, and assumed his identity. He has been sent to Earth to destroy the human race, believing that this would benefit the planet, but he begins to question the morality of his mission after involuntarily forming human emotions. He is fascinated by humans and has learned how to speak English, as well as how to masquerade as a medical examiner from watching reruns of ''Law & Order''. Although he attempts to blend in with people, he consistently stands out because of his misunderstanding of social cues and awkward speech and behavior. As the series progresses, he learns more about human emotions, behavior, and interactions, often closing episodes with a narration about what he has learned. He possesses superhuman strength, durability, and agility as well as advanced intelligence, shapeshifting abilities, and the power to alter or remove human memories. In the second-season finale, Harry is implied to be millions of years old, as he recalls seeing live dinosaurs.
