7	An adaptation of the [[ComicBook/ResidentAlien comic series]] by [[https://en.wikipedia.org/wiki/Peter_Hogan Peter Hogan]] and [[https://en.wikipedia.org/wiki/Steve_Parkhouse Steve Parkhouse,]] ''Resident Alien'' is a Creator/{{Syfy}} original series starring Creator/AlanTudyk as Dr. Harry Vanderspeigle, a semi-retired doctor in the small town of Patience, Colorado. Unbeknownst to all those around him, Dr. Vanderspeigle has a secret: he's an alien who has crash-landed on Earth and is now hiding among them.
8
9	Arriving with a secret mission to KillAllHumans, Harry starts off living a simple life... but things get a bit rocky when he's roped into solving a local murder and realizes he needs to assimilate into his new world. As he does so, Harry begins to wrestle with the moral dilemma of his mission and asking big life questions like: "Are human beings worth saving?" and "Why do they fold their pizza before eating it?"

11	The show premiered in 2021 and has aired two seasons, with a shortened third currently slated to premiere in early 2024. The season had originally been targeted for a fall 2023 premiere, but was delayed due to the Hollywood strikes, though filming had already been completed before the strikes began. An [[https://www.youtube.com/watch?v=s3xGm8rSX20 official trailer]] was released in January 2024, with a premiere date on February 14, 2024.

13	----
14	!!This show provides examples of:
15
16	* AccidentalMisnaming: Harry starts calling Ben "Mayor Snowflake" after hearing Sheriff Mike call him that, not realizing it was an insult.
17	* AdaptationalLocationChange: The series is set in the fictional town of Patience, Colorado. The [[ComicBook/ResidentAlien comics]] on which it was based are set in Patience, Washington.
18	* AdaptationalVillainy:
19	** In the original comic, Harry was a benign alien who crash-landed on Earth and was passing as human to keep himself hidden until rescue arrived. Here he murders the real Harry Vanderspeigle for his identity and was not only on a mission to wipe out humanity, but [[spoiler:fully plans to get back to it once he finds the device that his ship was carrying for that purpose.]]
20	** [[spoiler:The government agents hunting Harry in the comics were very much {{Punch Clock Villain}}s - people doing their job of tracking down alien life without malice, with the lead agent in the latest volume even making a point of non-fatally incapacitating a nurse at Harry's clinic while planting bugs. Here, Lisa murders a witness to Harry's arrival in only her second scene and implies it's on orders from above.]]
21	* AdultAdoptee: In the season 2 finale, Harry seriously considers adopting [[spoiler: the 28 years old son of the Alien Tracker who recently died. However, the man makes clear that he wants to leave on his own.]]
22	* AnAesop: Most episodes have a lesson of some sort that they are trying to teach, even if only mostly subtly. These are usually summed up in Harry's thoughts at the end of the episodes, such as "''Killing may make humans feel strong in the moment, but what I've begun to realize is, true strength comes from choosing not to kill. Maybe being truly human is about choosing to love instead. But with that love comes the pain I feel inside me.''" or "''Humans have discovered that there is strength in numbers. But maybe the strongest thing in their life is the person they are closest to. Everybody needs a friend, especially when they are in danger.''"
23	* AliensInCardiff: The series takes place in the small town of Patience which is apparently three hours from the nearest city with roads inaccessible most of the year. {{Lampshaded}} by Harry who points out no one in their right mind would choose to live in a place like that unless they were looking for somewhere to hide.
24	* AliensSpeakingEnglish: Just like in the comic, Harry knows English, only instead of being an experienced speaker, the TV version learned it in a matter of months by binge-watching ''Law and Order''.
25	* AppealToNature: Harry tries to justify his plan for genocide against humanity by saying everything dies in the end, and it's only humans that won't accept this as simply natural.
26	* ArtisticLicensePharmacology: [[spoiler:D'Arcy's]] painkiller addiction shows symptoms more consistent with a stimulant. Opioids in particular tend to present more as somnolence and central nervous system depression.
27	* ArtisticLicenseReligion: Sahar's explanation of Halloween being a holiday celebrating evil spirits and Satan stems more from propaganda to demonize it. In truth, Halloween is a holiday that has theorized origins in different traditions such as Christianity and Samhain. One belief of the holiday is to show reverence to the deceased. Another aspect that comes from Irish immigrants is the Jack-o'-Lantern, which is used to ward off evil spirits.
28	* {{Atlantis}}: Harry offhandedly mentions Atlantis was real, and apparently its destruction came about due to being overpopulated.
29	* AsHimself: [[Series/AncientAliens Giorgio Tsoukalos]] is one of the panelists at a UFO convention that Harry and Asta visit, [[AdamWesting shamelessly pushing his book]], and seeming to actually get a lot of details about Harry's galaxy right. He appears in the second season as a prisoner in General [=McCallister=]'s black-site on suspicion of being an alien. Harry, in his alien form, frees him, recognizing him from the convention. For his part, Giorgio is thrilled to see Harry again, as an alien, and shouts that he knew they were real.
30	* AutoErotica: In season 3, Harry gleefully tells Asta he and his girlfriend had sex inside her car repeatedly.
31	* AwLookTheyReallyDoLoveEachOther: Judy and D'Arcy are initially teased as bitter enemies until it becomes clear that they're actually good friends exchanging banter. They will regularly trade vicious barbs before transitioning to more amiable talk. In "Welcome Aliens," Judy seems truly upset that D'Arcy almost died, though she also uses it as an excuse to get a free drink.
32	* BadFuture: "The Alien Within" reveals the truth about Goliath: [[spoiler:He's actually Harry from a distant future where the bad aliens succeeded in destroying all human life and reducing the planet to a wasteland.]]
33	* BigBad: General [=McAllister=], who is ordering two agents - [[TheDragon Lisa Casper]] and [[MinionWithAnFInEvil David Logan]] - to find Harry the alien and ''kill'' any human who gets in their way.
34	* BlackComedy:
35	** So, so much of Harry's feud with Max, from his DoubleEntendre laden bar conversation with D'Arcy where he cluelessly cops to his various murder attempts (and that it won't be the last time, either) while she's flirting with him to his {{Indulgent Fantasy Segue}}s about killing him, including blowing up his house and dropping a piano on him.
36	** When Max tries to convince Sheriff Thompson about seeing an alien, the sheriff tells him in annoyance to go watch ''{{Series/Oz}}'' - a show famed for its violence and PrisonRape - to see what happens to people who wind up in jail.
37	** After being found drinking fresh milk from a live cow, Harry can only yell "it was consensual!" as he's chased away.
38	** Isabelle cooks meat for the alien who has assumed the form of her husband from a package that was part of a set covering the body of her ''real'' husband.
39	** When asked to name one thing he doesn't like about New York, Harry's blunt response is "9/11."
40	* BlatantLies:
41	** Harry brushes off Asta's bewilderment that he was able to smash her 220-pound ex-husband through a wall one-handed by telling her he does yoga. Later he tries to pass off being a squeaky-voiced adult on the phone to Max as having had a terrible tricycle accident in the past.
42	** The first guy to see Harry on Earth runs away in terror, leaving his hat and horse behind. By the time he recounts his story to [[spoiler:government investigators]] he's recounting it as some sort of [[Film/DirtyHarry Dirty Harry-esque standoff]], complete with absurd tough-guy dialogue.
43	** Sheriff Mike Thompson and Deputy Liv Baker come to the Patience Health Clinic and start questioning the nurse Ellen about the intern Jay, believing that Jay might have stolen one of the murdered doctor Sam Hodges's prescription pads. They ask Ellen what she thought of Jay and Ellen replies that she always thought that Jay was a bit shifty and quiet, like she was hiding something. Then, Asta Twelvetrees, Jay's mother (though that's not generally known yet because Asta had given her up for adoption) comes over and asks what's going on.
44	--->'''Ellen''': They think Jay stole the prescription pads. I said she was nice and would never do that.
45	* CouchGag: The openings start with ever-changing IKEA-like instructions on how an alien should act like a human, giving do's and don't's. Usually these instructions will also tie in to something that happens in the episode.
46	* DeadMansChest: After finally finding the real Harry's body, alien Harry hides it in a cooler in his basement, underneath a pile of frozen meat. The sheriff, Isabelle, D'arcy and the [[YouMeddlingKids meddling kids]] all try to get a look inside.
47	* DeadPersonConversation: After mixing sleeping pills and alcohol, [[note]]which his friends rightfully call him out on [[/note]] Harry passes out and argues with the corpse of the real Harry Vanderspiegle. [[spoiler:When he decides to disintegrate Dr. Vanderspiegle's corpse with his doomsday device, the body talks to him again.]]
48	* DeadPersonImpersonation: Harry is forced into this role when the townspeople of Patience need a new doctor.
49	* EveryoneWentToSchoolTogether: Asta, D'Arcy, Ben, Judy, and Liv grew up together in Patience. Old memories and classmates' names regularly come up in conversation.
50	** Justified in that Patience is a pretty small town with as far as we can tell only one high school, all the mentioned characters are of a similar age.
51	* FakeGuestStar:
52	** Meredith Garretson appears as Kate Hawthorne in every episode of the first season and has a fairly significant role but is nevertheless credited as a guest star. This continues to be the case in the second season, though she does eventually have an episode in which she doesn't appear.
53	** This is also the case for Elizabeth Bowen as Deputy Liv Baker. However, unlike Garretson, Bowen is credited as starring cast in the second season.
54	* FreeRangeChildren: Max and Sahar bike all the way to Harry's isolated cabin without notifying their parents on multiple occasions. Not even getting pulled over by the sheriff deters them.
55	* FurnitureAssemblyGag: The opening credits parody this - they are presented as IKEA-style how-to guides for real-life situations an alien [[HughMann masquerading as human]] would find himself in on Earth, with red Xs to depict comically failed results and similar checkmarks for how things theoretically should end up.
56	* {{Gaslighting}}: Harry does this to D'Arcy when she [[spoiler:discovers the body of the original Harry]] and she calls him out on it. Harry also tries this unsuccessfully on Max and, to an extent, Max's parents.
57	* GenreMashup: The promotional poster for the series describes it as being "The sci-fi murder mystery doctor dramedy Earth needs now."
58	* GlamourFailure: As in the comics, certain humans can see through Harry's disguise, and by what Harry terms "some bullshit" the mayor's son Max can see his true form. Harry even states the chance of a human carrying the necessary gene turning up in his tiny town in the middle of nowhere are one in a million.
59	** And, inversely, Max doesn't know what Harry's human "guise" looks like, and can't identify the picture of the real Harry as the alien.
60	* TheGreys: [[TheGhost While they do not appear on the show in the first season]], Harry does mention them by name multiple times, and considers them to be insidious assholes with an ass fetish. [[spoiler:From what is seen of the aftermath of their activities on Earth, Harry may have a point about them being assholes. Then comes the second season and they are revealed to be the new BigBad, who are planning to desolate the Earth and succeed in an alternate timeline.]]
61	* GreaterScopeVillain: TheGreys. Their actions play a crucial role in episode 9, as around the early 1990s they kidnapped multiple humans (for unexplained reasons) including an unborn baby right out of his mother's womb and so the vengeful father Peter Bach stalked and attacked Harry wrongly believing Harry to be responsible let alone ''aware'' of this infant kidnapping. [[spoiler:The second season establishes that their intentions are far more sinister.]]
62	* GreenAesop: The goal of Harry's KillAllHumans mission is to revert humans' influence on the Earth.
63	--> '''Harry:''' If a chicken sits on an egg for the right amount of time, you get a perfect little chick...but if you do not care about the egg, and you leave it in the sun, it rots and stinks. The Earth is the second one.
64	* HappilyAdopted:
65	** After her mom abandoned her, Dan had raised Asta (we don't learn what became of her birth father). She fully considers Dan to be her father, and they clearly love each other (he's a bit overprotective due to her {{domestic abuse}} from Jimmy though).
66	** Jay has an overall happy relationship with her adoptive mom (aside from the ordinary spats).
67	* HumanityEnsues: The whole point of the series.
68	* HumanityOnTrial: Harry is sent to Earth to KillAllHumans. By the end of the first season, he has changed his mind.
69	* HypocriticalHumor: When the foot of the original Harry is found in a lake, Harry is naturally keen to get rid of it, or at least get his hands on it. D’Arcy rebukes him:
70	-->'''D’Arcy''': [''to Harry''] Can you be a little less needy and a little more sensitive? Somebody’s died, so… [''to Sheriff''] Can we see the foot?
71	-->'''Asta''': What’s going on? Who does the foot belong to?
72	-->'''D’Arcy''': Yes, and can we touch it?
73	* IHaveThisFriend: Kate tries to ask Liv in Season 3 about some signs of having been abducted by aliens, talking about it "theoretically". Liv sees through this instantly though, and realizes Kate's worried she's been abducted.
74	* InsultBackfire: Harry's cluelessness about social interaction leads to a lot of this.
75	-->'''Asta:''' You want facts? OK, I'll give you two. One, you're kind of a dick.
76	--> {{Beat}}
77	-->'''Harry:''' [[ComicallyMissingThePoint That is just one]].
78	* IntergenerationalRivalry: Between Harry and ten-year-old Max. However, WordOfGod says Harry's [[ManChild emotionally]] around the same age.
79	* InterspeciesRomance: In Season 3, Harry starts a relationship with a woman from an [[BirdPeople avian species]].
80	* JurisdictionFriction: In the second half of season 2, Sheriff Mike has to deal with his counterpart from Jessup after Ben claims that a murder that happened in Patience actually happened in Jessup.
81	* KidsAreCruel: After Max creates his alien wanted posters, almost all his schoolmates either mock or avoid him. He makes a friend in Sahar by picking up the binder that a bully had knocked out of her hands.
82	* KillAndReplace: The real Harry Vanderspeigle is murdered in the pilot so the alien Harry can have a human form. Several episodes feature Harry's continuous attempts to keep the body hidden.
83	* KilledToUpholdTheMasquerade: The cowboy who encountered Harry in his alien form is killed by [[TheDragon Lisa]], whose orders were to deliver an alien to the general without anyone knowing about it. She comes close to killing various others who come too near the investigation for her liking.
84	* LocalHangout: Harry goes to Joe's Diner on a daily basis, which makes it easy for Max to find him. The 59 is also this due to being the one bar in town.
85	* MakingLoveInAllTheWrongPlaces: In Season 3 Harry starts having sex with his girlfriend all over the place, including the bathroom and up a tree.
86	* MedicationTampering: The town doctor who suffered from diabetes is killed by someone poisoning his insulin injections with botulinum.
87	* MurderIsTheBestSolution: Having NoSocialSkills and little idea of how humans operate in general, Harry's response to really aggravating humans is generally to try and kill them. In the space of the first episode alone he tries to kill Max for being able to see through his disguise and later comes within a breath of strangling Asta's abusive ex-husband to death after seeing him assault her, to which even Asta reacts in horror. Later on he immediately grabs a knife when [[spoiler:Max's mother comes to see him about his claims Harry's an alien, before realizing she thinks her son is making it all up.]]
88	* NeverFoundTheBody: One of Harry's many problems is finding the body of the original Dr. Vanderspeigle. After throwing him in the lake on the night he assumed his identity, he now worries the corpse will wash up on shore and expose his ruse. [[spoiler:It washes up in episode 3, with Harry managing to get to it before anyone else.]]
89	* NoTellMotel: Among Judy's jobs is working the desk at the Copper Ridge Motel, a seedy motel on the outskirts of Patience. In the second half of season 2, Harry and Asta dump a body there.
90	* NotStayingforBreakfast: Darcy struggles with this a lot and takes a major step towards opening herself towards intimacy when she reverses this trend.
91	* OddFriendship: Once the whole "trying to kill/expose the other" thing is put behind them, Harry enters this with Max (and by extension Sahar), with Harry using the boy to find his ship's components and Max coming over to see how he's doing the following episode.
92	* PerceptionFilter: PlayedWith. Initially, unlike the comics, Harry's human form is a physical transformation (and [[PainfulTransformation a painful one]] at that), but [[TheMirrorShowsYourTrueSelf his true alien form can be seen in any reflective surface]] - indicating it's a combination of illusion and physical changes.
93	* PragmaticAdaptation: In the original comic, Harry is always shown as an alien, while the show usually depicts him in his alien "disguise" so that the lead actor isn't saddled with wearing major prosthetic makeup through the whole show.
94	* PreviouslyOn: Each episode starts with a recap of previous events.
95	* PsychicPowers: Harry and his genetic relative Octopus both have psychic powers. Harry can alter memories, while Octopus speaks telepathically and can heal amnesia.
96	* QueerEstablishingMoment: It turns out that Jay is into girls when in Season 3 her adoptive mom mentions her new girlfriend.
97	* TheReasonYouSuckSpeech: Harry cruelly says Asta helps everyone simply to get love, while D'Arcy's a "bottomless pit of need", so the two feed off each other. Both however find his analysis all too accurate later, in spite of themselves. They get into a heated argument in the next episode over exactly these flaws, but it helps them to air their grievances.
98	* RevealingCoverUp: Even while he thinks killing Max is easier, Harry does realize that if something happens to the boy in a town this small right after he made such crazy accusations against Harry, it'll look suspicious.
99	* RunningGag:
100	** Harry's love of ''Series/LawAndOrder'', because he learned how to act human and speak English by watching episodes of the show.
101	*** Early on he makes a "chung-chung" noise when he makes a dramatic revelation.
102	*** In "Secrets" Harry mentions that he should have spent more time doing his job and less watching L&O marathons.
103	*** He describe his "hometown" of New York City by paraphrasing the intro.
104	*** When he imagines getting a job as a tattooist, he puts the face of Creator/JerryOrbach on his client.
105	*** When Harry mentions Creator/JerryOrbach to Max, Max has no idea who Orbach is.
106	*** In "141 Seconds," when he joins the Hawthornes on their trip to Yellowstone National Park, it is mentioned after they get there that he spent the whole trip reciting episodes of the show.
107	** Harry using vulgar terms in a medical context such as "tit" instead of "breast," or "prick" instead of "penis."
108	** Harry realizing too late that something is funny and gives a forced, awkward laugh.
109	** Harry saying something out loud, and then the audience being presented with his thoughts, these being the meanly comedic opposite of whatever he just said.
110	* ShoutOut:
111	** In the "Pilot," Max Hawthorne has a poster for ''Film/ETTheExtraterrestrial'' on the wall of his room and his father is mentioned as having let him watch ''E.T.'' ''E.T.'' was an Creator/AmblinEntertainment production and ''Resident Alien'' is from Creator/AmblinTelevision.
112	** Creator/NathanFillion is the voice of the Harry's cousin Octopus. Fillion and Creator/AlanTudyk were on ''{{Series/Firefly}}'' together.
113	** Everyone who realises what Lisa and David seems to describe them as Men in Black using dialogue from [[Film/MenInBlack the movie]]. General [=McAllister=] even snaps at David for "watching too many movies" when he calls them that.
114	** Harry and Asta discuss E.T. in "Girls' Night," in which Harry calls E.T. an idiot, albeit sexy and very attractive.
115	* SitcomArchNemesis: Initially an entirely one-sided example on Harry's part; he regards Max, the mayor's hapless young son, as a grave threat after it turns out he can see his true form through his disguise. Slightly darker than normal in that Harry then tries to [[AlcoholInducedIdiocy kill him when drunk]], while poor Max can only run away screaming. Following that, Max is still paranoid about Harry but otherwise has become more willing to stand up to him and even prank him out of spite, effectively becoming a more straightforward example of this. They finally grow out of it in episode 5, after some spectacular InsaneTrollLogic from Sahar Harry is unable to get past, calling a truce where Max stops trying to expose Harry and in return Harry calls off trying to [[spoiler:convince his parents he's insane]].
116	* SmallTownRivalry: Patience and Jessup, which is first brought to attention when the mayor of Jessup produces a tourism ad that takes shots at Patience's recent gruesome events.
117	* StrandedInvader: "Harry's" xenophobic people sent him as an advance scout to wipe out life on Earth for them, but things went haywire, he crashed his ship in middle of nowhere Colorado, and he lacks the resources to get back. Much of the show's comedy comes from his horrible attempts to blend in and his annoyance at how much he is GoingNative.
118	* StringTheory: Sheriff Mike builds a board of the crimes that had occurred (Sam's murder, washed-up foot, fake prescriptions). [[HyperCompetentSidekick Deputy Liv's]] secret board is much more detailed and offers new insights.
119	* SpecialGuest:
120	** Creator/LindaHamilton receives this credit for her role as General [=McCallister=].
121	** Creator/TerryOQuinn is so credited in "Welcome Aliens."
122	* SpiesInAVan: David and Lisa do their planning and monitoring from an RV.
123	* StealthInSpace: Harry's spaceship has a cloaking device that kept it from being discovered. That is, until the two agents track Harry to the landing location.
124	* TitleDrop: In the second season finale, "I Believe in Aliens," Deputy Liv Baker finishes her interview, part of a series of interviews of alien experiencers, with the phrase.
125	* TitleIn: Flashbacks are labeled with the time and location first in the script of Harry's language, then in English.
126	* TrojanPrisoner: Towards the end of the second season, an alien hunter gains access to a secret military base by bringing in an alien, namely Harry. This was all part of a ruse, and Harry breaks free once they are inside.
127	* TrueSight: In the first season, two people (Max and one-off character Peter Bach) have the one-in-a-million genetic mutation that allows them to see through Harry's human disguise.
128	* UnusuallyUninterestingSight: Very few people comment or look askance at Harry's bizarre behavior and speaking style, which normally would probably make them think he has a mental disorder or something.
129	* WhamEpisode:
130	** "End of the World as We Know It" sees [[spoiler:Asta finally discovering Harry is an alien, as well as Lisa discovering one of Max's posters of Harry's alien form.]]
131	** "Welcome Aliens" [[spoiler:has D'Arcy break into Harry's home - and discover the real Harry's corpse in the freezer]].
132	** "Alien Dinner Party" [[spoiler:sees an alien shoot and kill David Logan in the opening scene. This is followed up with the egg that Harry found in the previous episode hatching an alien baby. Said baby then clutches Harry's head and reveals a communication from a fellow alien that his people are ''not'' coming because there is another alien species already on Earth planning to try to take it over. Harry is shot by a man from human Harry's past, then Asta shoots and kills the man. However, in the process, D'Arcy stumbles upon the scene.]]
133	** "The Alien Within" reveals the truth about Goliath - [[spoiler:he's actually Harry from a distant future where the Greys wiped out all humans.]]
134	* WhamShot:
135	** If you had avoided most trailers, the opening scene of Harry in the back of the police car and the mirror showing his true alien form is jarring.
136	** In-universe for both Max and Harry as the boy sees the doctor in his true alien form.
137	** The flashback to the night "Harry's" ship crashed on Earth...and then showing that Asta witnessed it.
138	** The opening of episode 4 showing Harry dreaming of a nice day out on the town...then [[spoiler:activating his device which vaporizes everyone around him and showing what he's planning to do for the entire planet.]]
139	** The flashback opening of "Heroes of Patience," showing [[spoiler:the original Harry injecting Sam Hodges's insulin with botulinum, revealing that TheDeadGuyDidIt.]]
140	* WhatHappenedToTheMouse:
141	** Harry's backup job as Patience's therapist is dropped after "Homesick," though it is later revived in the second season.
142	** The idea of Harry having a job at all is dropped after "The Green Glow," even though that episode strongly implies that he needs one. "An Alien in New York" reveals that he discovered a "money bag" inside the cabin filled with numerous stacks of $100 bills, apparently a pay-off to the human Harry Vanderspeigle for [[spoiler:having killed Sam Hodges]]. But this still doesn't explain why he was so worried about getting a job, unless the money bag was a later discovery. Once again, it ends up coming back in the second season when Harry again agrees to be the town doctor.
143	* WorldOfJerkass: Played with; while most of the main characters have unpleasant edges initially, there's reasoning for it shown as the series goes along. Asta's initial snappishness with Harry is shown to be down to his replacing her ParentalSubstitute Sam, D'Arcy's being a complete prick to her patrons is because she never wanted to be a bartender in the first place, Max's increasing weirdness is understandable considering Harry tried to kill him (twice), Mayor Hawthorne's incompetence is because he's a well-meaning ExtremeDoormat, and Deputy Liv is more tragic than anything else. Even the sheriff's dickishness is eventually explained as having a DarkAndTroubledPast.
