History ReallySevenHundredYearsOld / LiveActionTV

** Ace Ukiyo of ''Series/KamenRiderGeats'' looks to be 21. He's actually almost 100 times that age, having been playing the Desire Grand Prix since 1 Anno Domini.

* On ''Series/ThirdRockFromTheSun'', "teenager" Tommy Solomon was actually the senior member of the alien team. Of course, his real age (and that of the rest of the family) was never revealed, so there is no way of knowing how much older Tommy was.

* ''Series/{{Sanctuary}}'': Helen Magnus used to date Jack the Ripper; she's 157 years old at the start of the series. For that matter, Tesla, Watson, and Jack the Ripper are also all older than they look for various reasons. The only member of the Five that isn't (The Invisible Man) is dead with a grown up granddaughter. Magnus' father is even older, and probably in his 180s-190s or so.

** In "[[Recap/TheTwilightZoneS1E24LongLiveWalterJameson Long Live Walter Jameson]]", the title character is more than 2,000 years old. He tells his close friend Professor Samuel Kittridge that he is old enough to have known Creator/{{Plato}} personally.
** In "[[Recap/TheTwilightZoneS3E90TheFugitive The Fugitive]]", Ben ruled his planet for more than 1,000 years before coming to Earth. He will live for at least another 4,000 years.
** In "[[Recap/TheTwilightZoneS5E143QueenOfTheNile Queen of the Nile]]", Jordan Herrick learns from Viola Draper that her mother Pamela Morris has not aged in at least 70 years. Just before she steals his LifeEnergy, Pamela herself tells him that she was once Queen of the Nile, making her more than 2,000-years-old.

** In "Monsters!", Emile Francis Bendictson appears to be in his early 80s but is a 158-year-old vampire.
** In "Welcome to Winfield", Weldon appears to be about 80 but will soon celebrate his 150th birthday. Most of the other residents of Winfield are also over 100 years old but look much younger. According to the closing narration, the median age of the townspeople is 112.
** In "The Last Defender of Camelot", Lancelot appears to be in his 60s but has lived for 1,000 years as a result of a spell cast by Myth/{{Merlin}}. Morgan le Fay is much the same age but she only looks to be in her early 30s.

* Henry Morgan in ''Series/Forever2014'' looks to be in his late 30s but is somewhere around 200 thanks to him being TheAgeless and possessing ResurrectiveImmortality. [[spoiler:Adam claims to be around 2000 in the second episode. In another episode, Adam asks Henry to locate an ancient Roman dagger that's 2000+ years old, implying that it's important to him. The dagger is later found and is revealed to have been one of those that killed UsefulNotes/JuliusCaesar, implying that Adam may be the ancient dictator himself]].

-->'''Kirk:''' You're a Metron?\\

* ''Series/GothamKnights2023'': The Talon turns out to be a [[spoiler:{{serial killer}} who supposedly was hanged for multiple murders over a century before.]]

* ''Series/MotherlandFortSalem'': Sara Adler is over three hundred years old, mentioning having made the Accord around 327 years earlier and served in the military ever since. She's played by a forty year old actress. {{Justified|Trope}}: [[spoiler:she's later shown to be a LifeDrinker feeding on the vitality of witches' called "biddies" which empowers her and stops Alder from aging physically.]]

* ''Series/MyDeadEx'': Madame Fortune relates that she was born in World War Two. After she'd died while around thirty however, Fortuna came back and stayed the same age ever since (though she uses makeup to disguise this too).

* Jadzia Dax (and her successor Ezri Dax) on ''Series/StarTrekDeepSpaceNine'' is an interesting case because, due to the symbiotic nature of her species she is both in her late 20s and hundreds of years old.
** Indeed, Sisko's teenage son Jake is quite pleased when urbane Jadzia turns into a ditzy twenty-something.
--->'''Jake Sisko:''' She is so cute.\\
'''Benjamin Sisko:''' She is also about 300 years too old for you.
* Adira Tal of ''Series/StarTrekDiscovery'' is another case of this being both a human teenager and also hundreds of years old due to their being the seventh host of the Trill symbiont Tal, who is several hundred years old by 3190.
* Guinan of ''Series/StarTrekTheNextGeneration'' is at least 500-years-old. At one point, Data's transported to the 19th century, where he spots Guinan having a conversation with Creator/MarkTwain at a dinner party. He assumes she was somehow sent back in time as well, only to quickly learn that this is actually her 19th century self. In the episode ''Rascals'', set in 2369, she says her father is 700.
** Tolian Soran, a member of the same race as Guinan and infamously the man to kill James T Kirk, was described as being "over 200 years old" by Dr Crusher (although interestingly he looked older than Guinan).
* Q from ''Series/StarTrekTheNextGeneration'' says that he and the rest of the Q species are "ageless" and "immortal." It’s also stated in "The Q and the Grey" that he has been in a relationship with another Q for at least 4 billion years.
* At the end of the famous episode of ''Series/StarTrekTheOriginalSeries'' "Arena" (the one with the [[PeopleInRubberSuits Rubber Suit]] monster Gorn), the Metrons are revealed to be HumanAliens.

** [[ComicBook/MartianManhunter J'onn J'onzz]] in ''Series/{{Supergirl|2015}}''. In the episode [[Recap/Supergirl2015S2E7TheDarkestPlace "The Darkest Place"]], he explains that he learnt a meditation technique back in the 1800s.

* On ''Series/{{Battlestar Galactica|2003}}'', [[spoiler:Galen Tyrol, Sam Anders, Tory Foster, Saul Tigh, and Ellen Tigh]] are really two thousand years old, though this is because of travelling on a relativistic ship. Even without that, they are OlderThanTheyLook, because their ship finished its journey at a time when Bill Adama was a teenager.
* Some of the vampires in ''Series/{{Being Human|UK}}'' fit this; Mitchell is over a century old, but looks mid-20s. His sire, Herrick, is even older, and looks middle-aged. Hal is considered one of the Old Ones and is over 500-years-old but looks to be in his 30s.

* Henry Morgan in ''Series/{{Forever|2014}}'' looks to be in his late 30s but is somewhere around 200 thanks to him being TheAgeless and possessing ResurrectiveImmortality. [[spoiler:Adam claims to be around 2000 in the second episode. In another episode, Adam asks Henry to locate an ancient Roman dagger that's 2000+ years old, implying that it's important to him. The dagger is later found and is revealed to have been one of those that killed UsefulNotes/JuliusCaesar, implying that Adam may be the ancient dictator himself]].

* ''Series/GothamKnights'': The Talon turns out to be a [[spoiler:{{serial killer}} who supposedly was hanged for multiple murders over a century before.]]

* In the DistantFinale of ''Series/{{Merlin|2008}}'', Merlin looks like he's in his 80s, but is probably well over a thousand years old. And his age could just be a magical disguise anyway.

* On ''Series/WonderWoman'', Steve Trevor comments, "You can't be more than 23 or 24," and WW responds, "I will be 2,527 years old on my next birthday." He doesn't believe her.

* ''Series/TheXFiles'': In "Tithonas" Alfred Fellig is revealed to be over two centuries old, while he looks around 65.

** Bennett Sutton, a drunk professor at Columbia, is actually the Count of St. Germain, born in the 16th century and made immortal by his brother Paracelsus in 1541. The same applies to Charlotte Dupres (the Countess) and Nick Powell (their son). Paracelsus himself survived by being bronzed (against his will).

* ''Series/{{Highlander}}'' featured two episodes about an immortal with the appearance of a 10-year-old. (Immortals stop aging whenever they are "killed" for the first time.) In his first appearance he claimed to have been immortal for only four years, but it turned out he was Really Eight Hundred Years Old and engaged in [[TheFarmerAndTheViper a repeated con job to gain other immortals' trust and take their heads]]. (This was his way of making up for combat disadvantage.)
** Of course almost every Immortal in ''Highlander'' follows the trope, because you just can't go around telling people you were born in 1592 when you look 30. If anything, the trope is sometimes ''reversed'' with some pretending they're older than they really are (eg, the man who pretends to be Methos).

** The oldest-surviving human in the franchise, meanwhile, is Koda, the Blue Ranger from ''Series/PowerRangersDinoCharge''. He looks like he's in his 20s, but is actually 100,000+ years old, due to a combination of being a HumanPopsicle and the blue Energem he held that granted him [[TheAgeless agelessness]].

** Armand is 514 years old in 2022, but he seems to be only in his 20s (his actor, 37-year-old Assad Zaman, is OlderThanTheyLook because he can still pass for a man in his mid-to-late 20s).
