History TheOuterLimits1995 / TropesQToZ

* ShapeshiftingSeducer: In "First Anniversary", the protagonist's wife is actually a foul shapeshifting alien, whose power makes her appear as every man's perfect woman. Unfortunately, the power starts to fade when used too much on someone, such as her husband.

* TheUnFavorite: In "Sandkings", Dr. Simon Kress has felt like this for his entire life as his father always favoured his brother David over him.

* TerminallyDependentSociety: In "The Haven", people have become incredibly dependent on the artificial intelligence Argus, which controls every aspect of life in the buildings in which it is installed. Many people try to avoid contact with others unless it is absolutely necessary. As a result, normal social interaction is rapidly becoming a thing of the past. Considering that its mandate is to promote the health and welfare of the people in its care, Argus deactivates itself in buildings throughout the city so that people will be forced to rely on each other for survival.

* RippleEffectProofMemory: In "A Stitch in Time", an already-unbalanced scientist uses her time machine to go back and execute notorious serial killers before they hurt anyone. Each time history changes, and she remembers each and every change, driving her crazier and crazier. In the end, [[spoiler: she (and a homicide detective following her murders) go back in time to save her younger self from the sexual assault which originally caused her problems. The scientist loses this (having essentially erased herself), but the detective gains it and realizes that her best friend was killed by one of the serial killers whom the scientist had no motivation to kill in the current timeline. The detective then starts killing serial killers...]]

* TeleportersAndTransporters: Important to the plot of "Think Like a Dinosaur".

* TimeCrash: In "Déjà Vu", a time travel experiment goes wrong [[spoiler: after an attempt to weaponize it by a corrupt military official]], which results in a GroundhogDayLoop...a rare GroundhogDayLoop with a time limit. Each iteration grows shorter, and eventually there will be no hope of preventing the Time Crash from destroying the world. [[spoiler: In the end, the disaster is averted, and the man responsible suffers a Karmic Fate Worse than Death, as he's caught forever in the moment of his own annihilation by the malfunctioning time machine.]]

* TrustPassword: In "Tribunal", the elderly Karl Rademacher from 1999 is brought back to Auschwitz in 1944 by Aaron Zgierski and Nicholas Prentice and forced to dress in the clothes of an inmate. When he is brought before him, he tries to convince the younger Rademacher that he is him from more than 50 years in the future by relating what happened on his tenth birthday: his father gave him a green bicycle and beat him when he drove it into a lake. [[spoiler: The younger Rademacher is disturbed by this since, as far as he knows, there is no way that this elderly Jewish prisoner could have known about that incident. He then shoots his older self in the head.]]

* ToServeMan: {{Subverted|Trope}} in "What Will the Neighbors Think?". From reading her mind, Mona Bailey comes to the conclusion that Tory Beth Walters killed Beck Sanders after a disappointing date and has used his body to make meat pies. Tory Beth is arrested and the pies are confiscated by the police. However, it turns out that Tory Beth was not being literal when it came to thinking about killing Beck. He had simply left the Clackson Arms in a hurry because he had been intimidated by Tory Beth's aggressive manner.

* TechnicolorEyes: In "I Hear You Calling", the strange man is identified as an alien by his purple eyes.

* TheWarOfEarthlyAggression: In "Tempests", Earth's offworld colonies sought their independence but lost the ensuing war against Earth. Many colonists feel that Earth authorities treat them poorly because of the war.

* TranslationConvention: "Promised Land" begins with the Tsal-Khan Dlavan and his grandson Ma'al speaking in their native language before it switches to English. From this point onwards, the audience hears the two of them, Krenn and T'sha speaking in English when they are interacting with each other and speaking in their own language when they are being observed by the escaped human slaves. The Tsal-Khan language also sounds quite aggressive to human ears, which serves to make them appear all the more intimidating.

* SinisterMinister: Father Claridge from "Fear Itself" murdered a little girl and burned her corpse before blaming her brother, turning the boy into a traumatized wreck for most of his life and haunted by the experience. [[spoiler:He ends up driven to madness by the brother's psychic powers, imagining himself burning alive.]]

** In the final scene of "Blank Slate", Hope is strapped to an operating table about to have her memory erased by Dr. Tom Cooper, with whom she had a brief relationship when his memories were erased.

* StrappedToAnOperatingTable: In "Last Supper", Frank Martin's flashbacks show Jade strapped to an operating table being experimented upon and tortured by Dr. Lawrence Sinclair to test the extent of her HealingFactor.

* TransferableMemory: A bit of a variation in "Donor". After Dr. Peter Halstead receives Timothy Laird's body in a full body transplant, he experiences flashes of Timothy's memories and related attributes. The first sign is a craving for a cigarette in spite of the fact that he has never smoked a day in his life. About six weeks later, he sees visions of Timothy's wife Deirdre and daughter Kylie, which he at first mistakes for an hallucination. One day while driving aimlessly, he arrives at Timothy's house, having been drawn there, and sees Deirdre and Kylie in the flesh. Under the pretext of being an acquaintance of Timothy, Peter starts to spend time with them. He assists Deirdre in coaching Kyle's soccer team, having essentially inherited Timothy's soccer skills. Peter eventually comes to share Timothy's love for Deirdre and tells her the truth about his identity. She is extremely upset at the revelation but she comes to terms with it after a while.

* TimeTravelEpisode: The time travel-based episodes are "A Stitch in Time", "Worlds Apart", "Falling Star" and "Vanishing Act" in Season Two, "Joyride" and "Tribunal" in Season Five, "Breaking Point", "Decompression", "Gettysburg" and "Final Appeal" in Season Six and "Patient Zero" and "Time to Time" in Season Seven.

** An episode has a member of a post-human extinction android society trying to resurrect the species through cloning. One of its comrades eventually betrays it, having concluded that the best way to serve the human race is to prevent the species' greatest threat: The existence of the human race.
** Another episode of the series featured an AI that totally controlled every feature of an apartment building with the purpose of looking after the complete welfare of the residents. This enabled the tenants to live without any other human contact. After an elderly resident died of a heart attack while the other tenants ignored her cries for help and the AI's alerts, the AI seemed to malfunction, invoking what looked like an AIIsACrapshoot incident. [[spoiler: As it turned out, the AI was trying to force the residents to work together and to ultimately destroy it, as it reasoned that its very existence, and the resulting human isolation, was detrimental to the welfare of the residents.]]

** In "Alien Radio", the controversial KXVY ShockJock Stan Harbinger takes great pleasure in belittling people who believe in conspiracies, predominantly involving aliens but also concerning more down-to-earth topics such as WhoShotJFK, on his radio show "The Harbinger of Truth". An encounter with an alien, which he at first tries to ignore and deny because it is inconsistent with his view of the world, turns him into a believer.

** In "The Grell", escaped Grell slaves start a rebellion against humanity to secure freedom for their people.
