->''"Tyrannosaurus is the most superb carnivorous mechanism among the terrestrial Vertebrata, in which raptorial power and speed are combined."''
-->-- '''Henry Fairfield Osborn''', the paleontologist who coined the new genus in 1905
%% One quote is enough, put any new one in the Quotes tab.

As noted in StockDinosaurs, ''T. rex'' is by far the most common dinosaur that appears in fiction. While it may not have been the biggest carnivorous dinosaur ever, it was probably among the most powerful and dangerous. It is certainly the most famous, mainly because it looks badass, and is also the ''only'' dinosaur popularly known for the whole scientific name (genus ''Tyrannosaurus'', species ''rex'') instead of just the first term. It helps the name was described by [[Webcomic/{{xkcd}} Randall Munroe]] [[https://xkcd.com/1056/ as]] [[AwesomeMcCoolName the most badass scientific name ever]] after ''Smilodon fatalis'' ([[PantheraAwesome Saber-toothed cat]]). The ''T. rex'' in general is often used as a RuleOfCool stereotype, and is a frequent target of the NinjaPirateZombieRobot trope. (Vampire ''T. rex'', [[https://www.youtube.com/watch?v=iAYf9YJSKXc anyone?]].)

In fiction, ''T. rex'', like all dinosaurs, seems to [[KillAllHumans really like the taste of humans]], despite the fact that we're fricking tiny compared to it (imagine passing on a turkey dinner to run a mile for Chicken [=McNuggets=]). Expect to see ''T. rex'' [[RoarBeforeBeating roaring constantly]] and [[BadVibrations shaking the earth with every step]] as well as always active and on the prowl, never stopping to rest in order to conserve its energy. RuleOfCool always wins, but in RealLife predators will tread softly and shut up while hunting; otherwise [[FridgeLogic how would they ambush their prey with success]]?[[note]] Palaeontologists now seem to think that ''Tyrannosaurus'' and other large theropods may not have roared at all and probably made hissing and growling sounds like crocodiles.[[/note]] It is also usually implied to be male, perhaps because ''Tyrannosaurus rex'' means "[[NamesToRunAwayFromReallyFast Tyrant Lizard King]]". Some scientists have suggested the females were larger; though this is plausible, solid scientific evidence for this hypothesis is not as strong as it used to be. In addition, large, adult ''Tyrannosaurs'' would hunt less and basically KillSteal the hunts of other carnivores and younger ''T. rexes''; the highly advanced olfactory sense of the creature allowed it to sniff out carrion from miles away. Said roar would have ''definitely'' helped scare off smaller dinosaurs from a kill.

In earlier fiction especially, ''all'' carnivorous dinosaurs on the bigger-than-a-human side tend to be confused with ''T. rex'', and ''T. rex'' itself will sometimes be depicted with non-tyrannosaur features, such as three fingered hands (tyrannosaurs only have two). Sometimes the authors will dismiss ''T. rex'' as "cliché" and use another large theropod as their DesignatedVillain. The attempt to be anti-cliché will usually be self-defeating, as the other theropod will tend to be used in such an inaccurate, Pseudo-Rex fashion that they might as well have just used the obligatory ''T. rex'' anyway. This tends to happen to poor ''[[StockDinosaurs Allosaurus]]'' most often, despite that fact that they really don't look that much like ''T. rex'', aren't that closely related, and aren't nearly as large. Fortunately, as new fossil evidence helps us straighten out how the various Theropods are related, this is becoming a lost subtrope. (See [[http://en.wikipedia.org/wiki/Theropoda that other Wiki]] for more information about this.)

In older fiction, tyrannosaurs and many other bipedal dinosaurs were typically portrayed in an upright "tripod stance" like a kangaroo (pretty much the only bipedal animal with a long tail early paleoartists could use as a model; see Franchise/{{Godzilla}}). ScienceMarchesOn, however, and by the '70s, it was generally agreed by the paleontological community that dinosaurs did not drag their tails. However, it wasn't until ''Franchise/JurassicPark'' came along in 1993 that this view managed to filter into pop culture: just the scene of a group of humans in a jeep being chased by a ''T. rex'' with that proper anatomic structure, and looking like she had a real chance of catching them, was enough to lock it in the public imagination. Even then, newer works still sneak in the tripod stance every so often, usually by showing ''T. rex'' in a "triumphant" pose that resembles the stance.

Its puny arms are a staple of ridicule. Very often they are thought of as useless, scrawny, and weak. Part of this is practicality; large arms would have gotten in the way of the ''T. rex'''s bite. Additionally, in spite of their size the arm bones show signs of large muscle attachment and thus, they were very strong and capable of lifting 200 pounds (90 kilograms). Because of this, ''T. rex'' might have used them to hold onto struggling prey while it dispatched it with its jaws. In addition, they could have also been used to help lift the ''T. rex'' from a sleeping position when it was waking up. Also, as with all theropods, its hands are almost always depicted as pronated, when this is now considered impossible in real life. They are supposed to face each other, like a person about to clap.

If a work of fiction involves TimeTravel, the probability of a ''T. rex'' appearing is directly proportional to the number of episodes. If the characters time-travel once in a series, they will either end up in a hilariously inaccurate version of the late Cretaceous and meet a ''T. rex'' or a hilariously inaccurate version of the Stone Age -- where they may meet a ''T. rex'' anyway. Likewise, a machine that merely pulls things out of the past, or other dimensions, seemingly has a 90% chance of grabbing a ''T. rex''. If the work of fiction supposedly ''doesn't'' involve TimeTravel, there's a good chance of the ''T. rex'' nevertheless [[AnachronismStew encountering critters from wildly different eras]], such as ''Stegosaurus'', which predates ''T. rex'' by a good 10 million years ''longer'' than ''T. rex'' predates us.

'''Note''' -- While we're here, a word about spelling, punctuation, and TaxonomicTermConfusion: the correct way to refer to the species is ''Tyrannosaurus rex'' or ''T. rex'' -- upper-case T, lower-case r, period after the T in the abbreviated version. And italicized. Not "T Rex", "T-Rex", "t-rex" and so on.

Also, there was far more than one kind of "tyrannosaur". The word "tyrannosaur" can be used to describe various relatives of ''T. rex'' belonging to the superfamily [[http://en.wikipedia.org/wiki/Tyrannosauroidea Tyrannosauroids]]. It turns out this group included members both large and powerful like the almost-identical Asian ''[[UsefulNotes/PrehistoricLife Tarbosaurus]]'' and the smaller North American ''[[UsefulNotes/PrehistoricLife Albertosaurus]]'' , ''[[UsefulNotes/PrehistoricLife Daspletosaurus]]'' and ''[[UsefulNotes/PrehistoricLife Gorgosaurus]]''. Earlier members were small and quick, such as ''[[UsefulNotes/PrehistoricLife Eotyrannus]]'' and ''[[UsefulNotes/PrehistoricLife Guanlong]]''.

Another important note: ''T. rex'' lived only in what is now central North America (ranging from about Alberta to Texas), so don't expect your time traveler to [[YouFailGeographyForever bump into them]] if they take off from anywhere else in the world ([[TimeAndRelativeDimensionsInSpace unless it's one of those time machines that can go to a different location]]). This is partly due to ScienceMarchesOn - specifically, the Asian ''Tarbosaurus'' was long suggested to be a species of ''Tyrannosaurus'', and in fact that's still debated among paleontologists.[[note]]The one known species, ''Tarbosaurus bataar'' ([[AwesomeMcCoolName Alarming Lizard Hero]]) is so similar to ''T. rex'' that the name ''Tyrannosaurus bataar'' might be more appropriate (though "Tyrant Lizard Hero" would be something of an oxymoron). Given the lack of surviving genetic samples from 65 million years ago to compare, it's probably impossible to know for sure.[[/note]]

In addition, ''Tyrannosaurus rex'' should never be confused for [[http://en.wikipedia.org/wiki/T._rex_%28disambiguation%29 another]] '' [[http://news.bbc.co.uk/2/hi/science/nature/8623332.stm ''T. rex''.]]''

* A large number of Dinosaur-type monsters, especially the more powerful ones, in the ''TabletopGame/YuGiOh'' card game are based on ''T. rex''. The menacing looking Black Tyranno, the inaptly named Ultimate Tyranno whose effect could backfire, Super Conducter Tyranno, who currently holds the title of the most powerful monster that can be normal summoned, and finally, Tyranno Infinity, [[ThereIsNoKillLikeOverkill whose effect can make him one of the most powerful monsters in the game]].
* While the ''Franchise/{{Zoids}}'' franchise has mecha based off all sorts of animals, one of the most common appears to be ''Tyrannosaurus rex''. Many of them are completely fantastic and bear no resemblance to the real animal (even accounting for their being huge robots), but even then they are supposedly "Tyrannosaurus-types". Oddly enough, several Zoids that aren't Tyrannosaurus-types, such as Deadborder, Gravity Saurer and Gojulas Giga are often mistakenly identified as Tyrannosauruses, both in English and Japanese (and, for the record, are ''Tarbosaurus'', ''Suchomimus'' and ''Giganotosaurus'', respectively).

There are also anthropomorphic armoured tyrannosaur warriors ([[Anime/DigimonAdventure WarGreymon]], [[Manga/DigimonNext VictoryGreymon]], [[Anime/DigimonSavers ShineGreymon]]). Digimon really, ''really'', loves the rex.

* ''Anime/{{Doraemon}}''
** The 2006 movie has a ''T. rex'' attack the main heroes and a herd of ''Alamosaurus'', only to be tamed by Doraemon with some Momotaro-esque dangoes.

* ''[[ComicBook/TwoThousandAD 2000 AD]]'' has rich people riding "tame" (and anatomically inaccurate) ''T. rex''es across Mars hunting poor people. Said ''T. rex''es were sourced by time travellers who went back to hunt dinosaurs for their "flesh".
* ''ComicBook/MonicasGang'': Horacio, a '''vegetarian''' ''T. rex'' created by Brazilian artist Maurício de Sousa (who is basically his AuthorAvatar, being the only of Mauricio's characters that continues to be only written by him).

* One of the many adversaries which ComicBook/JudgeDredd has to overcome during "The Cursed Earth" arc is cloned a ''T. rex'' named Satanus.
* Although set in the paleolithic era, ''ComicBook/{{Rahan}}'' sometimes features throwback dinosaurs, including a ''Tyrannosaurus rex'' in one issue. Rahan manages to kill it by planting a metal spear on its head during a thunderstorm, which then attracts lightning, frying the ''T. rex''.
* The Marvel Comics character [[http://en.wikipedia.org/wiki/Devil_Dinosaur Devil Dinosaur]] is a scaly, three-fingered red ''T. rex''. Along with his [[EverythingsBetterWithMonkeys ape-like]] partner Moon-Boy, he is a native of "Dinosaur World", a version of Earth in a parallel universe where dinosaurs co-exist with tribes of primitive humanoid beings.
* Called [[CallARabbitASmeerp shivats]] in ''ComicBook/XenozoicTales'', they make a few appearances. One saves Jack's life by eating an ''Allosaurus'' that has been pursuing him. Not on purpose, of course, Jack is too insignificant for the shivat to notice.
* ''ComicBook/PocketGod'' has Chicken, a ''T. rex'' who chases the pygmies in issue 3. He falls a cliff, but comes back as a zombie in issue 9, as part of the ''Infestation'' CrossThrough. [[CloudCuckoolander Nooby]] befriends him, but has to make him leave the island. When the pygmies are attacked by a giant octopus in issue 11, Chicken rises out the ocean to save them. The two disappear under the water and haven't been seen ever since.
* A ''T. rex'' made a brief appearance in ''ComicBook/MyLittlePonyFriendshipIsMagic'' Issue 16.
** Another ''Tyrannosaurus'' with Fluttershy's coloring and cutie mark appeared in the seventeenth issue.
* ''ComicBook/SuperDinosaur'' is a ''T. rex'' genetically modified to be smaller and smarter - close but not-quite-human in both respects. Also, many of the villains are anthropomorphic dinosaurs; and one of the major ones is Tyrannosaurus X.
* ''ComicBook/{{XTNCT}}'': The leader of the group of [[TurnedAgainstTheirMasters rogue dinosaur soldiers]] is a Tyrannosaurus Rex [[ADogNamedDog named Rex]].
* ''ComicBook/XMen'' has a couple of examples.
** In ''Uncanny X-Men #62'', the original five X-Men visit the Savage Land and find themselves face to face with a tyrannosaurus. Cyclops gives it a face full of optic blast.
** In ''Uncanny X-Men #19'' (of the 2010s renumbering), Magneto is attacked by a tyrannosaurus. This is actually not an example of the usual "inexplicable taste for human flesh" -- it's being mind-controlled by Psylocke.

[[folder:Comic Strips]]
* ''ComicStrip/TheFarSide'' has "the awesome Tyrannosaurus Mex" ruling the land SouthOfTheBorder. Of course, the king of the dinosaurs has been the subject of several other cartoons like one where a family is sitting around the dinner table. The father is holding a bowl of mashed potatoes and saying to his wife "Hey look, I am trying to pass the potatoes!...My arms are just as useless as yours."
* In ''ComicStrip/CalvinAndHobbes'', Calvin in his fantasies often imagines himself as a Tyrannosaurus gorging himself on hapless humans or picking a fight with the ferocious saber-toothed tiger (Hobbes). Later strips has him more accurately terrorizing other dinosaurs in the Late Cretaceous. Then there was also the strip where Calvin put [[NinjaPirateZombieRobot Tyrannosaurs in F-14s]].
* The titular character of ''Todd the Dinosaur'' is a 7-year-old ''Tyrannosaurus'' living with his adoptive human family.

* The main character, Rexy, and his mother from the Hungarian animated short ''Animation/PangeaTheNeverendingWorld''.

[[folder:Fan Works]]
* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfic ''[[http://www.fanfiction.net/s/8085799/1/Pinkassic-Park Pinkassic Park]]'', several ''Tyrannosaurus'' were accidentally released into the research compound and serve as major antagonists towards the main characters.
* The first dinosaur that appears in ''Fanfic/RiseOfTheGaleforces'' is Devil Dinosaur (see the Comics section above). Later chapters would introduce the tyrannosaur family from ''WesternAnimation/IceAge3DawnOfTheDinosaurs'', with the father being an adult version of Chomper from ''WesternAnimation/TheLandBeforeTime''. [[RefugeInAudacity And to top it off,]] [[spoiler:Violet later obtains a OneWingedAngel form called V-Wrex -- an armor-plated ''T. rex'' that speaks through {{Telepathy}} and is ImmuneToBullets.]]

[[folder:Films -- Animation]]
* One pops up in ''Disney/MeetTheRobinsons''. He's actually not so bad once the bowler hat comes off. He did hog up a lot of the ads, though. The focus on his only speaking scene lead to him becoming the EnsembleDarkHorse.
* ''Disney/{{Fantasia}}'' features a fight between a ''T. rex'' and a ''Stegosaurus''. Guess who wins? Though some fans mistake the creature for an ''Allosaurus'', they pretty explicitly call it a ''Tyrannosaurus'' in the intro to the Rite of Spring sequence, and concept art also refers to it as a ''rex''. It has three fingers simply because [[ArtisticLicense Walt thought it looked better that way]].
* Rex from ''WesternAnimation/ToyStory'' is an inversion of the usual depictions, as he is very timid and insecure. He does try to be fearsome, but he fears it might come across as annoying instead.
* ''WesternAnimation/IceAge3DawnOfTheDinosaurs'' features a mother ''T. rex'', who turns out not to be that bad at all. In fact, even she is afraid of the film's real BigBad, a huge white ''Baryonyx'' (related to ''Spinosaurus'', but lacking a sail) that goes by the unlikely name of [[FluffyTheTerrible Rudy]]. That still doesn't stop her from coming back in the end and [[CrowningMomentOfAwesome kicking his ass]].
* The ''Carnotaurus'' in Disney's ''Disney/{{Dinosaur}}'' is another example of the "Pseudo-Rex" trope in action. While much smaller than ''T. rex'' in reality, the filmmakers beefed it up to tyrannosaur size in the film. This issue is compounded by the fact that the animatics for the film depict a ''T. rex'' in place of the ''Carnotaurus'', suggesting that the filmmakers merely shoehorned the Carno's into a role originally written for ''T. rex''. Considering the film is set in North America, where the ''T. rex'' lived but ''not the Carnotaurus'', the ''T. rex'' would actually be more accurate. [[HandWave Handwaved]] by Kron being surprised about the Carno being "this far North". No kidding.
* A T. rex is the antagonist in ''WesternAnimation/TheLandBeforeTime'', referred to by all of the other characters as a [[CallARabbitASmeerp sharptooth]]. Chomper, a sharptooth who appeared in two of the sequels joins the cast in the TV adaptation.
* The protagonist of the film ''Anime/YouAreUmasou'' is a ''T. rex'' named "Heart", who raises a baby ''Ankylosaurus''.
* The BigBad of ''Animation/SpecklesTheTarbosaurus'' is a ''Tyrannosaurus'' named One-Eye.
* In ''WesternAnimation/{{Minions}}'', a ''T. Rex'' was the Minions' first master. Their incompetence led to its death.
* ''WesternAnimation/TheGoodDinosaur'' features a family of ''T. rex'' cattle ranchers as supporting characters.
* ''Animation/TheMindsEye'' treats us to a sequence with ''T. rex''. Made out of ''chromium''!
* ''WesternAnimation/TheSpongebobMovieSpongeOutOfWater'' gives us ''Squidasaurus Rex''.

[[folder:Films -- Live-Action]]
* The 1925 film ''Film/TheLostWorld'' marks ''T. rex'''s first ever appearance on the big-screen. Although ''Allosaurus'' is supposed to be the main predator of the film, the tyrannosaur shows up for one scene where kills an ''Agathaumas'' (a dubious genus of ceratopsian) that just gored the allosaur to death, proving to be the stronger predator.
* ''Franchise/JurassicPark''
** [[Film/JurassicPark The first movie]] has a ''T. rex'' chasing the heroes all over the place -- though it's somewhat of a subversion, as the real threat is the Velociraptors. Additionally, in the original film, she ''is'' seen hunting actual dinosaurs, and at one point gives up on chasing the protagonists when they outrun her in a jeep. And finally, she comes back at the climax of the film to [[spoiler:[[VillainousRescue save the protagonists from the raptors]]]].
** ''Film/TheLostWorldJurassicPark'' upped this by having ''three'', including a baby, and the [[PapaWolf Papa Rex]] goes on a rampage in southern California.
** ''Film/JurassicParkIII'' has the ''T. rex'' killed by the larger ''Spinosaurus'', which is more likely a [[ArtisticLicensePaleontology fish eater]] or [[http://en.wikipedia.org/wiki/Spinosaurus#Feeding_ecology generalist carnivore]] than the unstoppable BigBad the film made it out to be. The ''Spinosaurus'' falls under the "Pseudo-Rex" trope mentioned above. Somewhat justified, as Grant mentions, since these aren't real dinosaurs, but mutations. The animals were bred by [=InGen=] using non-dinosaur filler-DNA and raised in environments (and with other animals) they may have never otherwise encountered. This would lead to strange behavior at best, and outright mutation into new species at worst (which is essentially what happened).
** The park in ''Film/JurassicWorld'' has been successful enough for years to have regular ''T. rex'' feeding sessions without a hitch. However, the park has made dinosaurs so mundane over the course of a decade that [=InGen=] scientists decide to make a completely new hybrid dinosaur called ''[[NamesToRunAwayFromReallyFast Indominus rex]]'', whose DNA was mostly based on T-Rex but with additions from ''Giganotosaurus'', abelisaurs, cuttlefish, [[spoiler:and ''velociraptors'']]. Notably however, the film features the return of the exact same female Tyrannosaurus from the first film, still around on the island after 20 years and with scars on her neck from her encounter with the Velociraptors.
** It should be noted that despite the fact that ''T. rex'' had been appearing in media since at least half a decade after its initial discovery, the ''Jurassic Park'' franchise is easily the TropeCodifier for this dinosaur's modern image.
* In ''Series/{{Blackadder}} Back and Forth'', Blackadder and Baldrick briefly end up in the late Cretaceous period. Guess what's waiting for them.
* ''Film/KingKong''
** King Kong in the original [[Film/KingKong1933 1933 film]] battles a ''T. rex''.
** The [[Film/KingKong2005 2005 version]], and its various merchandise, actually subverted this trope. There, the family of ''T. rex''-like dinosaurs were called ''Vastatosaurus rex'', apparently a kind of Tyrannosaur that had been evolving for all the 65 million years the rest of the dinosaurs were dead, into the forms seen in the film. However it does have Kong fighting no less than ''three'' of them at once, all over one tiny little human. Who one of them chased for several hundred metres, despite carrying a perfectly good dead animal in its mouth most of the way. It tore half of it off in the process, the half it lost being BIGGER than the human it was chasing.
* Franchise/{{Godzilla}}'s design was based on a ''T. rex'', with the dorsal plates of a ''Stegosaurus'' and the forelimbs of an ''Iguanodon''. In the films, however, depending on the continuity, he is either a huge, prehistoric sea monster, or a mutated specimen of the fictional "Godzillasaurus". Incidentally, a theropod from the Triassic period was [[TheRedStapler later named Gojirasaurus]], after the movie monster, though it bears no resemblance to Godzilla beyond being a large, bipedal reptile.
** In the original script for ''Film/GodzillaVsKingGhidorah'', Godzilla was [[WhatCouldHaveBeen supposed]] to be a ''Tyrannosaurus'' before his mutation. Special effects designer Shinji Nishikawa decided against it and instead came up with Godzillasaurus.
* The Ray Harryhausen film ''Film/TheValleyOfGwangi'' features the title dinosaur, Gwangi, who was [[InNameOnly billed as an Allosaurus]] but was modelled after a Tyrannosaurus.
* The ''T. rex'' is the DesignatedVillain in the B-movie ''Film/PlanetOfTheDinosaurs''.
* The SoBadItsGood ''Aztec Rex'' featured what the [[{{Mayincatec}} Aztec]] InNameOnly local tribe called "Thunder Lizards", worshipping them and leaving sacrifices because they keep the valley free of intruders.
* ''Film/NightAtTheMuseum'' has the skeleton of a ''T. rex'' coming to life at night. But it's actually very friendly. It likes drinking water out of a fountain, playing fetch with its own rib, and generally [[AllAnimalsAreDogs behaves like a gigantic dog]].
* One ''T. rex'' appears in the 2009 ''Film/LandOfTheLost'', nicknamed "Grumpy" (the same nickname given to him in [[Series/LandOfTheLost the original 1970s TV series]]). Creator/WillFerrell's character, Dr. Rick Marshall, insults him, by claiming that his brain is the size of a walnut, causing a personal grudge to develop between them. Grumpy later tosses a huge walnut at the group during the night, bigger than a baby carriage, before slinking off into the jungle with a sinister smirk on his face. After a few further chases, Grumpy swallows Marshall whole, before returning at the end of the film with Marshall on his back [[BigDamnHeroes to save the others]]. Turns out, whilst Marshall was in Grumpy's stomach, he dislodged some sort of intestinal blockage, causing Grumpy to [[{{Squick}} literally poop him out]] and be in a much better mood afterwards. The walnut joke is perhaps made funnier in that it is actually false that Tyrannosaurus had a brain that size (it was actually almost as large as a human brain). The only dinosaur considered to have a brain the size of a walnut is ''Stegosaurus'', which is also false in that its brain was actually twice the size of a walnut.
* The ''Film/SuperMarioBros'' movie featured King Koopa, a tyrannical ruler whose ancestry dated back to the prehistoric ''T. rex''. This heritage gives Koopa a feeling of entitlement and divine right, which was the pretense under which he took control of the government. After a brief stint in a [[DevolutionDevice devo chamber]], Koopa periodically "flicks" in and out of a reptilian appearance before finally [[spoiler:de-evolving backwards through four different stages of ''T. rex'' and then primordial sludge.]]
* The 2008 version of ''Film/JourneyToTheCenterOfTheEarth'' has a ''T. rex'' chasing the protagonists. They later ride a boat made out of a T. rex skull.
** WordOfGod states it's a ''Giganotosaurus'', but it looks more like a ''T. rex'' with thumbs.
* The little-seen movie ''Film/TammyAndTheTRex'' has the brain of Tammy's boyfriend put into a robotic ''T. rex'' by a MadScientist for... some reason. Never really explained.
* The 2014 children's film ''Film/DinosaurIsland2014'' features a [[ShownTheirWork feathery]] ''[[ShownTheirWork T. rex]]'' [[ShownTheirWork with a chunky, birdlike body frame]]. There's also a brief TakeThat to ''Film/JurassicPark'' and its depiction of the ''T. rex's'' eyesight...
-->'''Kathryn:''' What are you doing!?\\
'''Lucas:''' It can't see us if we don't move!\\
'''Kathryn:''' Where did you get a silly idea like that!? It can see you fine, run!
* In ''Film/RebirthOfMothra3'', When Mothra Leo travels back in time, he encounters Cretaceous King Ghidorah terrorizing several dinosaurs. King Ghidorah is so huge that he can carry a ''T. rex'' in one of his mouths.

* Leigh Clark's novel ''Carnivore'' deals with a ''T. rex'' that goes on a rampage [[MisplacedWildlife in an Antarctica research station]] after being hatched from a frozen egg ''and'' exposed to radioactive waste.
* Sue, the ''T. rex'' at the Chicago Field Museum shows up in ''Literature/TheDresdenFiles'' book ''Literature/DeadBeat'', though mostly only as the display of bones you'd expect in a museum. [[spoiler:Until the climax, where Harry [[NinjaPirateZombieRobot reanimates it]] and ''[[CrowningMomentOfAwesome rides it into battle]]'' against a [[NightOfTheLivingMooks horde of zombies]] and necromancers.]]
* ''T. rex''es are featured in the ''Literature/{{Dinotopia}}'' books, obviously.
** The spinoff novel ''Dinotopia Lost'' explores the full implications of ''T. rex'' parents going MamaBear! James Gurney does his homework, though, and numerous other large theropods appear as well, including ''Allosaurus'' and ''Giganotosaurus''.
** ''Journey to Chandara'' also portrays some ''T. rex''es who are scavengers, and don't actually hassle the unarmored human and tiny ceratopsian passing through. Given that many smaller carnivores are apparently able to live in civilization and eat fish, one wonders if these might join them.
* Robert Sawyer's ''End of an Era'' featured ''T. rex''es.
* As did his ''Literature/QuintaglioAscension Trilogy''. Not only is the "Blackdeath" clearly a tyrannosaur, the Quintaglios themselves are HumanoidAnimals descended from the smaller Tyrannosauroids.
* The Literature/{{Animorphs}} encountered ''T. rex'' in the time-traveling Megamorphs special, and, of course, used it as their go-to battle morph once they managed to acquire one (that morph [[ResetButton was lost]] in the transition back to the present). Two of them, however, only had ''[[RaptorAttack Deinonychus]]'' morphs. [[BloodKnight Rachel]] complains about this.
* In ''Literature/ASoundOfThunder'', hunters go back in time to shoot a ''T. rex.''
* Creator/LSpragueDeCamp's "A Gun for Dinosaur" (more time-traveling big game hunters) features ''Tyrannosaurus trionyches'', a fictional cousin of "the famous ''rex''."
* The first book of Steve Alten's ''Meg'' series, has a ''Tyrannosaurus'' being killed by a ''{{Megalodon}}'' (a really big prehistoric shark supposedly related to the Great White) whilst chasing Hadrosaurs in the shallow sea. This scene is factually wrong, as not only did ''Megalodon'' not even live in the same time period as any dinosaur (try almost 50 million years after they went extinct), but the scene was clearly thrown in [[TheWorfEffect purely to try and present ''Megalodon'' as a more lethal predator]] (an oceanic predator being more effective in its element than a land predator? [[SarcasmMode Never!]]). No prizes for guessing what would happen if (in Alten's version of prehistory) a ''Megalodon'' beached itself on the shore whilst a hungry Rex was passing by.
* Nina Bangs's ''Gods of the Night'' series features 11 immortal men, 10 of which are fused with the souls of the ultimate prehistoric predators, among them (of course), a ''T. rex'' called Ty. It's worth noting that each of these characters were referred to by some shortened form of the dinosaur or predator they were fused with.
* In the first set of ''Literature/{{Dinoverse}}'' books, a boy ends up inhabiting the body of a ''Tyrannosaurus rex'', while three others ended up possessing different prehistoric creatures. On their quest to get back to their own time and bodies, they are menaced by a "''[[PrehistoricMonster Tyrannosaurus imperator]]''", a fictional dino even bigger than the rex but otherwise identical. This one is perhaps justified, since it was one of the Imperator's bones added to the time machine which got it to take the kids back to that period in the first place. Other books feature different kids in the bodies of different dinosaurs from other periods of time, but there's always someone in each group in a huge theropod - acrocanthosaurus, carcharodontosaurus -- which gets compared to ''T. rex''.
* The Museum of Unnatural History in the ''Literature/{{Nightside}}'' books at one point has a live one in a cage. The Collector moved the entrance to his hideout there, so he could use the creature to protect his most prized treasures.
* Subverted in ''Literature/{{Carnosaur}}'', in which a ''Tarbosaurus'' raised by a carnivore-obsessed billionaire is the main threat instead. Lampshaded in that everyone who sees it assumes it's a ''T. rex''. [[spoiler: Later in the end, a pair of ''Tyrannosaurus'' were cloned and hatched, and they deliver KarmicDeath to the billionaire's insane wife.]]
* The main antagonist of the first ''Literature/TheMagicTreehouse'' book is one. Also appears in the anime movie, where it was actually portrayed with [[ShownTheirWork non-pronated hands]].
* ''Of course'' a book titled ''Literature/TheDinosaurLords'' has Tyrannosaurs in it. There aren't many, but each of them (except for the old, toothelss and blind Imperial Executioner) is feared and causes awe in all onlookers - and for a good reason. The most commonly-seen example is [[FluffyTheTerrible Snowflake]], albino mount of vilainous count Falk.
* ''Primitive War'' features a family of ''Tyrannosaurus'', all of which [[ShownTheirWork have feathers]].
* ''Literature/KingOfTheDinosaursTyrannosaurusRex'': It's a small book about the T-Rex and to a lesser extent dinosaurs in general.

[[folder:Live-Action TV]]
* There were ''T. rex''es in all versions of ''Series/LandOfTheLost''. The original series (and the Will Ferrell movie) had him nicknamed "Grumpy".
* Any time ''Franchise/SuperSentai''/''Franchise/PowerRangers'' does a dinosaur theme, the ''Tyrannosaurus rex'' gets TheHero treatment as the [[LawOfChromaticSuperiority Red Ranger]]'s patron dino: ''Series/KyoryuSentaiZyuranger''/''Series/MightyMorphinPowerRangers'', ''Series/BakuryuuSentaiAbaranger''/''Series/PowerRangersDinoThunder'', and ''Series/ZyudenSentaiKyoryuger''/''Series/PowerRangersDinoCharge''.
** Also featured in ''Series/MiraiSentaiTimeranger'' / ''Series/PowerRangersTimeForce'', with the V-Rex/Quantasaurus Rex (or Q-Rex) mecha. And sure enough, when Wes and Eric visit {{Prehistoria}} in ''Time Force'', they encounter the real thing.
** There's also the ''T. rex''-like [=GouJyuJin=] (mainly [=GouJyuRex=] mode) from ''Series/KaizokuSentaiGokaiger'' which, fittingly enough, is intended as a InternalHomage to ''Zyuranger'', ''Timeranger'', and ''Abaranger''. ''Series/PowerRangersMegaforce'' takes it and even names it the Q-Rex in honor of the ''Time Force'' mecha.
** Other ''T. rex''-themed mecha include ''Go-Onger''[='s=] T-Line and ''Goseiger''[='s=] Tyranno Headder, both of which stick a Tyrannosaur head on a vehicle.
** Tie-in movies featuring the Kyoryugers have loved to play up their ''T. rexes''. ''Superhero Taisen Z'' includes a shot of ''all'' the various Rex mecha listed above ([[MyFriendsAndZoidberg and a sauropod from]] ''Shinkenger'') working together; and while the annual Versus movie is nominally ''Kyoryuger vs. Go-Busters'', the actual main selling point is that ''Zyuranger''[='s=] and ''Abaranger''[='s=] Red Rangers are showing up too and bringing their Tyrannosaur mecha to team up with Kyoryu Red and ''his'' Tyrannosaur.
* In ''Series/MrBean'', our hero sees a Nativity set in a department store and stages a special drama. Guess what menaces the Holy Family before being driven off by tanks and [[Series/DoctorWho a Dalek]]? [[http://www.youtube.com/watch?v=XDOO3FvGsZ4 See it to believe.]]
* On ''Series/{{Sliders}}'', the heroes sometimes slide into Earths where dinosaurs have survived (alongside humans or not). Initially averted, as the first big predator to chase them is an ''Allosaurus'' (and described as such). In a later episode, though, they meet the obligatory ''Tyrannosaurus rex''.
* The last episode of ''Series/WalkingWithDinosaurs'' focused on a mother ''Tyrannosaurus rex'' trying to raise her three babies in the unforgiving Late Cretaceous. [[ColonyDrop A meteorite]] [[RocksFallEveryoneDies fell, and]] [[DownerEnding everyone died.]]
* The first episode of ''Series/PrehistoricPark'' centers on Nigel's attempts to obtain a ''Tyrannosaurus rex'' for the park. [[spoiler:He does -- two juveniles who grow up over the course of the series.]]
* Speaking of Impossible Pictures and dinosaurs... it was refreshingly {{averted}} in ''Series/{{Primeval}}''... except for [[http://en.wikipedia.org/wiki/Extinction_Event one of]] [[ExpandedUniverse the novels]]. Finally makes an onscreen appearance in the penultimate episode of series 5. Of course, by this point the show had already dealt with other large predators like ''Giganotosaurus'' and ''Spinosaurus'', so the ''T. rex'' feels much less JustForFun/{{egregious}}.
* Referenced, but not seen, in an episode of ''Series/StargateAtlantis''. One particular member of the expedition have begun to suspect [[ProudWarriorRaceGuy Teyla]] of leading the Wraith to her team because of how often they seem to show up. When Sheppard's team is yet ''again'' running for their lives back to the gate, he immediately assumes this is the case again... when Sheppard and Ford inform him the Wraith had nothing to do with it, and they were just chased by something very much like a ''T. rex''.
* ''Series/DoctorWho'':
** [[Recap/DoctorWhoS11E2InvasionOfTheDinosaurs Invasion of the Dinosaurs]]" has a ''T. rex'' brought to London via TimeTravel.
** Subverted in [[Recap/DoctorWhoS33E2DinosaursOnASpaceship "Dinosaurs on a Spaceship"]]. The characters find a fairly young ''T. rex'' sleeping (although one still big enough to at least ''look'' menacing). It gets a brief OhCrap moment when they suspect they might have run into a nest, but wisely decide to get the heck out of there before any adults find them or the young ''T. rex'' in front of them wakes up. There's a brief but tense sequence involving their attempts to tiptoe around it, but we never actually see any other tyrannosaurs.
** In "[[Recap/DoctorWhoS34E1DeepBreath Deep Breath]]" the TARDIS is vomited up by a {{Kaiju}}-sized ''T. rex'' by the shores of the Thames. [[RentAZilla She's not the focus of the story]], however, and is perfectly docile. She just wanders around as a background element until she's abruptly killed by the episode's real antagonist.
* The final episode of ''Series/DinosaurRevolution'' focused on a family of ''T. rexes'' and an antagonistic ''T. rex''. [[spoiler:They all die.]]
* Never shows up in the flesh on ''Series/TerraNova'', but Taylor had a desk partly made out of a T. rex skull, because he was a badass.
* [[Series/BarneyAndFriends Barney]] supposedly is a ''T. rex'' or similar dinosaur, but acts nothing like the stereotype described above except for the tripod stance.
* Though not giving much focus to ''T. rex'', ''Series/DinosaurPlanet'' does have an episode featuring ''Daspletosaurus'', a smaller member of the same family. [[spoiler:The real deal eventually appears at the end of the episode in a cameo, explicitly stated as being evolved from ''Daspletosaurus''.]]
* ''T. rex: A Dinosaur in Hollywood'', a TV program which is all about the history of ''T. rex'''s discovery and role in popular culture.
* Double subverted in the documentary ''Series/PlanetDinosaur''. ''Tyrannosaurus rex'' never shows up in the series, with the focus largely being given to less well-known fauna of the Mesozoic. However, the king is very frequently mentioned as essentially a measuring stick for how strong every other creature is, showing that its legendary reputation precedes it.

* Best known for the GlamRock hit "Bang a Gong (Get It On)", Music/MarcBolan's band was originally ''called'' "Tyrannosaurus Rex".
* "[[http://www.youtube.com/watch?v=IfHzJU-Rlo4 Your two-penny prince, he'll give you hot love, oh-ho-ho...]]"
* Music/WeirdAlYankovic
** The FilkSong "Jurassic Park": ''"Someone let ''T. rex'' out of his pen I'm afraid those things'll harm me 'Cause they sure don't act like [[Series/BarneyAndFriends Barney]]...''" Cut to a ''T. rex'' chomping Barney's head off, later to puke it out after getting the Heimlich maneuver from a brachiosaurus.
** ''"A huge Tyrannosaurus ate our lawyer. Well, I suppose that proves they're really not all bad"''.
* A list here wouldn't be complete without listing "[[https://www.youtube.com/watch?v=fNeAINi9omo Mesozoic Mind]]", sung by a guitar-playing ''T. rex''.
** Also, "''I hid behind a wall of rock when Allosaurus roared''". Poor ''Allosaurus''. The [[PoorMansSubstitute Poor Man's]] ''T. rex''.
* ''WesternAnimation/SchoolHouseRock'' has a song called "Tyranosaurus Debt", which portrays America's national debt as a dinosaur that keeps growing larger and is always hungry for more money.
* "Gor-Gor" by Music/{{GWAR}} is about the [[CrazyAwesome title giant, mutant, crack-fueled Tyrannosaur destroying America.]]
* As you might be able to guess from the title "[[http://tgwtg.bandcamp.com/track/the-t-rex-song The T-Rex Song]]" (note: curse heavy) released by Music/TheGreatLukeSki and Creator/DougWalker in the wake of ''WebVideo/TheNostalgiaCritic'' review of ''Franchise/JurassicPark''. Mostly a spoken song about a talking ''T. rex'' living in modern times going about his day-to-day business till someone pisses him off and he then eats them.

* ''3-D Ultra Pinball: The Lost Continent'' has at least one, who can eat the pinball whole. To make matters worse, the protagonist is named Rex, leading a scientist to this: "That's interesting... Rex meets ''T. rex''."
* Atari's ''Pinball/MiddleEarth'' has one front and center on the playfield, as part of the game's LostWorld theme.
* Prominently featured on the playfield of Creator/DataEast's ''Pinball/JurassicPark'' pinball. He follows the ball during the game, and if the opportunity arises he'll bend down and grab the ball in his jaws.
** [[Pinball/TheLostWorldJurassicPark The sequel]]'s WizardMode has a ''T. rex'' rampage in San Diego, just like [[Film/TheLostWorldJurassicPark the film it's based on.]]
* In ''Pinball/PoliceForce'', the criminal BigBad is a ''T. rex'' named Mafiosaurus Rex.

[[folder:Puppet Shows]]
* Although many are loath to acknowledge it, [[Series/BarneyAndFriends Barney]] is (supposedly) a ''T. rex''. Indeed, the sight of one of the most badass animals ever being turned into a cuddly giant plush toy who is friend to children everywhere is certainly one of the reasons why Barney is so despised.
** Some sources claim that Barney is actually an [[RaptorAttack Utahraptor]], which sounds much more disgraceful.
** Some artists set out to [[http://th07.deviantart.net/fs13/PRE/f/2007/086/4/9/PC_Barney_by_lucky2563.jpg make things]] [[http://www.cracked.com/photoplasty_83_22-awesome-ways-to-reboot-classic-tv-shows_p22 right]], however.
** Lampshaded in Ian [=McDowell=]'s short story "Bernie". A cloned (and very well-trained, and sedated) mini-theropod is created to do public appearances as a Barney-{{expy}}. [[KillAllHumans It does not end well...]].
** It says something about America that, when brainstorming what creatures would be suitable hosts for a show aimed at the pre-''Series/SesameStreet'' demographic, Barney's creator thought ''a gigantic bloodthirsty carnivore'' was a perfectly rational choice.
** It's rumored that in one episode, someone called Barney out on this by asking "Aren't you a meat eater?" To which Barney replied, "Oh, now I only eat veggies."
* In ''Series/{{Dinosaurs}}'', Earl's best friend is a bachelor ''T. rex'' named Roy. He was not ferocious at all, a bit on the dumb side, and had a tendency to angst about his tiny little arms (which, like most of the show's dinosaurs, have an extra, opposable digit).
-->'''Roy:''' Why am I always picked last on the bowling team?

* The pixelated ''T. rex'' that appears when Google Chrome is unable to connect to the internet.

[[folder:Tabletop Games]]
* Partially subverted (like many things) in ''TabletopGame/{{Exalted}}'', where a Tyrant Lizard, while a seriously dangerous creature to mortals, is not only not the toughest of the animals in the world, it's not even a real challenge for an Exalt (you play an Exalt in most games). However, if you are one of the said mortals, then run. Run as fast as you can, 'cause this thing will eat you and your house [[AndYourLittleDogToo and your village]].
* ''TabletopGame/SmashUp'': The most powerful minion for the Dinosaur faction (and the most powerful minion for any faction that doesn't come with some sort of drawback) is the redundantly-named "King Rex".
* ''TabletopGame/{{Warhammer 40000}}'': While technically belonging to a birdlike species, [[http://images2.wikia.nocookie.net/__cb20080303213907/warhammer40k/images/b/b8/Greater_Knarloc_Model.jpg there is no denying a Kroot Greater Knarloc]] is just as badass.
* The [[LizardFolk Lizardmen]] of ''TabletopGame/{{Warhammer}}'' can use a Carnosaur as a mount, which is essentially a ''T. rex'' in all but name.
* Tyrannosaurs, along with various other well-known dinosaurs, appear in ''TabletopGame/DungeonsAndDragons'' as monsters. It is also possible for players to get them as allies -- high-level druids can take a ''T. rex'' as an animal companion, and casters can summon celestial or fiendish versions. Yes, that's right -- an evil cleric can quite literally summon a demonic ''T. rex''.

[[folder:Theme Parks]]
* The climax of the former ''Ride/BackToTheFutureTheRide'' at the Ride/UniversalStudios parks involved the riders getting sent back to a primeval Hill Valley, where they were briefly menaced by a ''T. rex''.
* In most versions of the ''Ride/BigThunderMountainRailroad'' coaster at the Ride/DisneyThemeParks, the ride ends with the guests zooming by an excavation site where the skeletal remains of a ''T. rex'' have been uncovered.

* Takara Tomy has released a fully articulated ''Tyrannosaurus'' [[note]]labelled as ''Tyrannosaurus'' instead of ''T. rex''[[/note]] figure as the first dinosaur figure under the ''Ania Animal Adventure'' line, with the mouth, legs and tail being moveable. It comes with three different colours as well as a feathered variant.
* ''Franchise/{{Transformers}}''
** "Me Grimlock most famous Transformer to have ''T. rex'' alt mode!"
** The original Grimlock turned into the more outdated "kangaroo"-postured ''T. rex''. More modern versions of the character, like in WesternAnimation/TransformersAnimated have more scientifically accurate builds.
** A number of others have had ''T. rex'' modes (or at least [[BroadStrokes ones that to a layman resemble a]] ''[[BroadStrokes ''T. rex'']]'') such as Trypticon, and ''WesternAnimation/BeastWars'' [[BigBad Megatron]], ''[[VerbalTic yeeeessss]]'' (albeit a ludicrously under-sized one).
** Despite [[CriticalResearchFailure how inaccurate]] the Bayformer quadrilogy could be in many sciences, the Grimlock in ''Age of Extinction'' is actually somewhat accurate to the real ''T.rex'', even down to the scaling between him and Optimus Prime being the same as the scale of a human to a normal ''T.rex''...and ''properly digitigrade feet in beast mode''! Granted, he has massive horns jutting out the back of his head and pronated arms (neither of which ''T.rex'' had), but the accuracy is fairly outstanding for a medium like Transformers (which has never really concerned itself with being on top of science).

[[folder:Video Games]]
* ''Franchise/SuperMarioBros'' features many dinosaurs, some of which are inspired by ''T. rex''; series staple Yoshi is a cutesy caricature of one, and is a sapient egg-laying frugivore rather than a carnivore. ''VideoGame/SuperMarioOdyssey'' features a photorealistic (if not completely accurate) ''Franchise/JurassicPark''-style ''T. rex'' for Mario to [[GrandTheftMe Capture]] and wreak (benevolent) havoc with.
* It wouldn't be ''Franchise/JurassicPark'' without one. The tie-in games all featured it as a boss, and ''The Lost World'' platformer had it as a playable character, wrecking havoc on the hunters. ''Warpath'' also featured it as a playable character, out of a lineup of similar big, badass carnivores (and four herbivores).
* The dinosaur hunting simulator ''VideoGame/{{Carnivores}}'' features the ''T. rex'' as the most dangerous game animal. As soon as it detects the player, it will sniff the air then start charging at a frightening speed. And it can be only killed via a shot in the eye; shooting it at any other spot will simply agitate it.
* ''Savage Quest'' is an arcade game where you play as a ''T. rex'' rampaging against other dinosaurs, big lizards, and cavemen to retrieve your eggs from a wizard.
* ''VideoGame/DeadOrAlive 4'' has a stage filled with dinosaurs, including a ''T. rex'', despite taking place in the modern day. A story-mode cutscene that takes place in the stage has the dino terrorize Hitomi before Jann Lee kicks it in the face and knocks it out with one punch, saving her life. Hitomi chastises him for hurting it, the ungrateful bitch.
* ''VideoGame/StarFoxAdventures''
** The [=RedEye=] tribe consists of ''T. rex''es.
** The [=SharpClaw=] tribe is based slightly more on ''Allosaurus''. Their leader, [[BigBad General Scales]], even seems to resemble a small, anthropomorphic ''Giganotosaurus'' a bit more than a ''T. rex''.
** Then there was the only enemy of the "Walled City"', the "Red Eye" tribe, and [[ExpositionFairy Tricky's Father]] was to be sacrificed to "King Red Eye", who lived under the city. Both were NightmareFuel, and unbeatable until one learned how to kill them properly.
* The appearance of Rexy in the first ''Franchise/TombRaider'' game was so iconic that he even made a cameo appearance in ''Tomb Raider II'', ''III'' and ''Golden Mask'', later returning in ''Anniversary''. Three guesses who's on the menu each time.
* A common enemy type in ''Franchise/FinalFantasy''. See also DinosaursAreDragons. To name a few:
** The ''Allosaurus'' from ''VideoGame/FinalFantasyI'', as well as the ''[[MetalSlime Tyrannosaur]]''.
** Tyrannosaurs from ''VideoGame/FinalFantasyVI''. The Earth Dragon also took on this form.
** T-Rexaurs from ''VideoGame/FinalFantasyVIII''. You will occasionally find one roaming the Training Area in Balamb Garden if you walk around long enough, which tends to be fatal if you attempt this at the start of the game.
** The Tyrant enemy class in ''VideoGame/FinalFantasyXII'' definitely count. Notably, the Earth Wyrm, which is larger than all the other ''T. rex'' types, and the ''T. rex'' boss from the demo.
* One of the more awesome segments of ''VideoGame/ParasiteEve'' takes place in a museum with a dinosaur exhibit. Her nemesis has control over a large quantity of mitochondrial goo that can apparently bring the fossilized dinosaurs back to life. The boss of the area is, of course, a ''T. rex''. [[DinosaursAreDragons That breathes fire.]]
* A recurring boss from ''[[VideoGame/JoeAndMac Joe & Mac: Caveman Ninja]]''. The last level took place [[WombLevel inside it, even]].
* ''VideoGame/ChronoTrigger'' has the heroes square off against a ''T. rex'' that [[DinosaursAreDragons breathes fire]] in the prehistoric era. Its descendent shows up in a later optional dungeon.
* ''VideoGame/PrimalRage'' has two ''Tyrannosaurus rex''-shaped gods named [[NamesToRunAwayFromReallyFast Diablo and Sauron]].
* ''Franchise/{{Pokemon}}'':
** Tyrunt and its evolution Tyrantrum are Rock/[[DinosaursAreDragons Dragon]]-type Pokémon revived from a fossil. As Tyrunt evolves into Tyrantrum, it gains a [[AwesomeMomentOfCrowning crown]] and a BadassBeard, making it look like a stereotypical king. Upon their introduction, Tyrunt and Tyrantrum were the only Pokemon with the ability [[ManBitesMan Strong Jaw, which powers up biting moves]], a clear reference to ''T. rex'' having some of the most powerful jaws of any terrestrial predator. [[ShownTheirWork They also have more feathers than half the depictions on this page combined,]] with Tyrantrum's in particular resembling a RegalRuff.
** Some other Pokémon have traits of ''T. rex'', even if not directly based on it like the Tyrunt line. Tyranitar is named after ''Tyrannosaurus'' in English, but is more of a ShoutOut to Franchise/{{Godzilla}}, who himself is based on dinosaurs. The Legendary Pokémon Groudon is an AnimalisticAbomination that resembles ''T. rex'' and similar dinosaurs.
* ''VideoGame/KingdomHearts3DDreamDropDistance''
** The Tyranto Rex dream eater is a [[AmazingTechnicolorWildlife very colorful]] [[DinosaursAreDragons fire breathing]] one, predictably packing a truckload of HP and attack power. You fight an appropriately sized one as a mini-boss, but the rest are small by ''T. rex'' standards (though still one of the largest normal dream eater varieties), looking around to be eight feet tall or so. [[VocalDissonance They also sound kind of like angry housecats.]]
** It also has a [[DemBones skeletal]] variant known as the Skelterwild, which is even worse/better, due to having freezing breath and the ability to detach their heads to have them attack independently of their bodies.
* ''VideoGame/KingdomOfLoathing'' has ''Tyrannosaurus "Tex"'' as a mini-boss you might encounter during the Naughty Sorceress quest.
* In ''VideoGame/WorldOfWarcraft'', beware of the [[BossInMookClothing Devilsaurs]] in [[LostWorld Un'goro Crater]]. Unless of course you're a hunter who has learned the "Tame Exotic Beasts" skill.
** Two are encountered in Northrend: A rare spawn in Sholozar Basin and an optional boss in Drak'tharon Keep.
** With the introduction of Zandalari Dinomancers in Pandaria, they've been turned into beasts of war. Oondasta was the most difficult world raid boss at the time of his release and Thok the Bloodthirsty is a boss in the Siege of Orgrimmar.
* ''VideoGame/{{Turok}}: Dinosaur Hunter''. The second-to-last boss is a HollywoodCyborg ''T. rex'' with armed FrickinLaserBeams.
* Burn Dinorex/[[ShoutOut Mattrex]] from ''VideoGame/MegaManX5'', which is yet ''another'' fire-breather. Well, he is a ''robot''.
** Another robot one shows up as a MidBoss in ''VideoGame/MegaMan7'' in Slash Man's stage. And the fossils (again, robotic?) appear in Freeze Man's stage in the same game.
** One of the Sigma Stage bosses in ''VideoGame/MegaManX1'', D-Rex, was intended to be a [[HumongousMecha humongous ''T. rex'' mecha]], but by the time the base was discovered by the protagonists, only the head was complete, forcing Sigma to convert it into a tank.
* Both ''VideoGame/DinoCrisis'' and ''VideoGame/DinoCrisis2'' (think ''Franchise/ResidentEvil'' meets ''Franchise/JurassicPark'') have the protagonists being pursued by SuperPersistentPredator ''T. rex''es. The [[VideoGame/DinoCrisis3 third game]] features ''mutant undead T. rexes.''
* Both ''VideoGame/FreedomForce'' games feature ''T. rex''es.
* In the end of the Soviet campaign in ''[[VideoGame/CommandAndConquerRedAlert2 Red Alert: Yuri's Revenge]]'', the defeated villain Yuri highjacks a time machine and attempts to escape. Soviets manage to override the controls of the machine and overload its core and send Yuri one-way straight to prehistoric times. Gues who's waiting for him there. Note that in this case the ''T. rex'' is actually a ChekhovsGunman, as in the first Soviet mission if you move really quickly when you're accidentally sent back there you can capture one and return it to the present -- where you can send it on a rampage in present-day San Francisco. It seems to have gained much tougher skin in the time travel tripe than the dozens you have no choice but to slaughter before you make the return trip -- you can take out most of the enemy base with "Rexy" alone.
* ''VideoGame/{{Lineage 2}}'' has an entire island of dinosaurs. The ''T. rex'' is a raid-boss like, aggressive mob that will, occasionally, eat other dinosaurs and be surrounded by a glowing blue effect. They normally wander around a set area (per 'rex) but there's one or two that walk around the whole Primeval Forest. And they're also aggro. The developers actually kept the poor eyesight of the ''T. rex'', and have given players a chance to run away: if you see the ''T. rex'' say "?" it means you have been noticed.
* ''VideoGame/FossilFighters'' uses ''T. rex'' as its mascot. However, the only way to obtain one without trading is during the PlayableEpilogue, ''after'' beating the game! It's also the hardest single dinosaur to find. The game treats it as an InfinityPlusOneSword, but it is much less so in comparison to the likes of [[spoiler:King Dynal]]. The sequels scale it back a bit; the ''T. rex'' is still powerful and makes it onto the packaging, but not quite ''as'' powerful or prominent as it was before. The third game, ''Fossil Fighters: Frontier'', also gives the player a sidekick that's like a little ''T. rex'' (but is instead a made-up species called a Nibblesaurus).
* The original ''VideoGame/ApeEscape'' has our protagonist travel through many different eras from pre-history through to the far future... in order to catch rogue monkeys with a net. One early level featured a mini-boss monkey astride a ''T. rex''.
* ''VideoGame/BanjoTooie'' features the Baby T-Rex and Daddy T-Rex transformations. The latter has a roar powerful enough to frighten cavemen away.
** [[GiantFootOfStomping Stomponadon]] is assumed to be a ''T. rex'' or some other large carnivorous theropod judging by the shape of his feet.
* ''VideoGame/{{Culdcept}}'' games feature a ''T. rex'' card as well as the "Mesozoic Song" spell which causes all of your placed monsters to become ''T. rexes'' in battle!
* ''[[VideoGame/PrehistoricIsle Prehistoric Isle in 1930]]'' features a Godzilla-sized ''T. rex'' as the final boss, the sequel has (sorta) normal sized ones as sub-bosses.
* ''Tyrannosaurus'' is one of the playable dinosaurs in ''VideoGame/PrimalCarnage'', and the [[SuperToughness toughest of any class]].
* In the UsefulNotes/PC88 version of ''VideoGame/DragonSlayer'', one of the enemies sort of looks like a Tyrannosaurus, and apparently is supposed to be one. Oddly enough, it's the second weakest enemy.
* In ''VideoGame/AdventuresOfDinoRiki'', the second boss is a fire-breathing Tyrannosaurus.
* The BigBad of ''VideoGame/LostEden'' uses ''Tyrannosaurus'', called Tyrann, as invading armies.
* ''VideoGame/EVOSearchForEden'' has ''Tyrannosaurus'' (called Tyrasaurus in the English version) as the boss of Chapter 3. They are very strong and hard to attack without the right features. They return again as survivors in later chapters, but are [[DegradedBoss reduced to mere enemies]] and humbled - after being hunted by a Yeti family in Chapter 4, they are saved by the FinalBoss and made into his servants. There are also ''Allosaurus'' (Omosaurus in the English version), which serve as TheDragon for the ''Tyrannosaurus'' in Chapter 3. While not as powerful, they are also hard to inflict damage.
* ''Dinosaur Hunting'' has ''Tyrannosaurus'' with a feather mohawk. Surprisingly, in this game they are mere mooks (although one is a mini-boss), and easy to bring down if you have the right formula. Later near the end, two ''T. rex'' corpses were found, torn to pieces by an unknown gigantic predator. [[spoiler:Implied to be a giant mutated ceratosaur who the final boss, which also kills a ''Spinosaurus'']].
* ''3-D Monster Maze'', the first 3-D game ever made, involves you trying to navigate a maze while avoiding a ''T. rex''. For a game with retro graphics, it is pure NightmareFuel.
-->''Rex has seen you!''
* Among the more wackier enemies to appear in ''VideoGame/SeriousSam2'' is the T-Mech, a cigar smoking T.rex biomechanoid. It's backstory reveals that it is the son of the Major Biomechanoid from the previous games, explaining the [[SuspiciouslySimilarSubstitute resemblance]].
* The BigBad of ''The Adventures of Bleeposaurus'' is a ''T. rex'' named King Tyrannus. Interestingly, the main character is a ''Triceratops''.
* ''VideoGame/SonicAndTheSecretRings'' featured a ''T. rex with horns and a spiked tail''.
** ''VideoGame/SonicRushAdventure'' gives us the Ghost Rex, which is basically a robotic ''T. rex''.
* ''VideoGame/RobotDinosaursThatShootBeamsWhenTheyRoar'', obviously, features a player character named Tyrannosaurus X.
* ''VideoGame/ViewtifulJoe 2'' has Drill Sargeant Big John, a '''T. rex''' wearing a military helmet and vest.
* In ''VideoGame/LiveALive'', O-D-O, the final boss of the prehistoric chapter is a ''Tyrannosaurus'' who is worshipped as a god by a caveman tribe. [[ArtisticLicensePaleontology Before your inner palaeontologist starts sobbing]], this is the ''only'' non-avian dinosaur seen in the level, making it likely that's it's the [[LastOfHisKind Last Of Its Kind]].
* The Dragos in ''VideoGame/{{Mother 3}}'' are essentially ''T. rex''es with small, pointy ears, though the baby ones look like an entirely different species. They're also friendly, unlike most of the examples, [[spoiler: at least until one of them is [[UnwillingRoboticisation transformed]] into a [[CyberneticsEatYourSoul cyborg]]...]]
* One appears in the [[{{Prehistoria}} Cascade Kingdom]] in ''VideoGame/SuperMarioOdyssey''. It can even be cap-tured and controlled by Mario! Other Tyrannosauruses appear in other kingdoms, but they have to be rendered unconscious (i.e. either sleeping, or dazed as a result of smacking into something while chasing you down) before you can actually control them.
* In ''VideoGame/WiiPlayMotion'', the final enemy of the ''Trigger Twist'' minigame is a Tyrannosaurus rex that will chase your Mii down.
* ''Videogame/MonsterHunter'':
** Tigrex, a type of Flying Wyvern. It has a head that heavily resembles that of ''T. rex'' from Jurassic Park, and as its name implies, is a wyvern version of both a tiger and a T. rex.
** "Brute Wyverns", [[DinosaursAreDragons a category of theropod dragons]]. One of them is the infamous [[NamesToRunAwayFromReallyFast Deviljho]] which is a ''T. rex'' mixed with {{RentAZilla}}.
** The Anjanath in ''VideoGame/MonsterHunterWorld'' is a Tyrannosaurusoid monster. While its head is the correct shape, its arms are incorrectly pronated and sized more appropriately for an ''Appalaciosaurus''. Unique to the game is its vulture-based feather coat, with its head bare and body coated in gray-black feathers. It also has the obviously fantastical addition of an expandable noseridge and fins along its spine in addition to [[DinosaursAreDragons breathing fire]].
* Adoptable in ''VideoGame/ZooTycoon'', in the Dino Digs or Extinct Animals expanions for 1 and 2. Very Popular. Very hungry.
* A ''Tyrannosaurus Rex'' is one of four StockDinosaurs to appear in the [[JungleJapes Amazon stage]] from ''VideoGame/{{Strider}}'', ressurected as part of the Grandmaster's experiments. There's also the fourth boss in the [[CanonDiscontinuity non-canonical]] ''Strider Returns'', which is a [[PirateNinjaZombieRobot fire-breathing, half-rotten cyborg alien Tyrannosaurus]] with a {{BFG}}.
* The FinalBoss in ''VideoGame/PrehistorikMan'' is the [[FossilRevival reanimated skeleton]] of a huge ''Tyrannosaurus Rex'' so big only its head is visible during the battle.
* One of Simmons's forms in ''VideoGame/ResidentEvil6'' has him transforming into a zombie ''T. rex'' in his battle against Leon and Helena.
* ''VideoGame/PuttPutt Travels Through Time'' had a timid but otherwise friendly ''Tyrannosaurus''. This is also probably one of the few works to remember ''T. rex'''s tiny arms [[ShownTheirWork are actually very powerful]].
* ''VideoGame/PlantsVsZombies2ItsAboutTime's'' Jurassic Marsh has them as one of the dinosaurs. They will use a MightyRoar to scare all zombies in its lane, [[StatusBuff making them move and eat much faster]]. If [[MookFaceTurn charmed by the Perfume-Shroom]], it eats the zombies for a OneHitKill, including Gargantuars. Strangely enough, said ''T rex'' has lots of inaccuracies, for one, it has pretty large arms and it [[AllAnimalsAreDogs sits down on all fours while panting and wagging its tail like a dog]].
* ''{{VideoGame/Saurian}}'' features one as one of the playable dinosaurs. Unlike most depictions, [[ShownTheirWork it is covered in feathers]], which it is believed to have possessed in real life.
* In ''VideoGame/HolyUmbrella'', the Donderasaurus is essentially a ''T. rex'' in spiky armor. It's TheDragon to Emperor Dondera, though not [[DinosaursAreDragons a dragon]].
* ''VideoGame/ArkSurvivalEvolved'' logically has a ''Tyrannosaurus'', being a [[DinosaurMedia video game with dinosaurs]]. ''However'', it's a ''T. dominum'' (that's "Tyrant Lizard Lord", to you!) instead of a ''T. rex''. It's a lot like a ''Franchise/JurassicPark''-[[ArtisticLicensePaleontology style T. rex]] though, except [[DomesticatedDinosaurs you tame it and]] [[RuleOfCool ride it around]].
* ''Franchise/SpyroTheDragon'':
** ''VideoGame/SpyroYearOfTheDragon'' features ''T. rex'' cowboys as enemies in the level "Dino Mines". There are two types: one is green and shoots with a pair of guns (very accurately, too) while the other is blue and throws dynamite sticks.
** In ''VideoGame/SpyroEnterTheDragonfly'', much of the [[{{Mook}} Riptocs]] are based on ''T. rex''. One in particular is the T-Rex 1000, robotic ''Tyrannosaurus'' that [[EyeBeams fire lasers from one eye]] with deadly accuracy.

[[folder:Web Animation]]
* Terry from ''WebAnimation/DinosaurOffice''.
* King Rexxtopher from ''WebAnimation/MightyMagiswords''. [[ShownTheirWork Commendably]], he may be the first cartoon ''T. rex'' to be portrayed with feathers, although he is very much cartoonish and stylized such as having a kangaroo-stance and an additional opposable digit.
* ''WebAnimation/DSBTInsaniT'': ???'s [[Franchise/{{Digimon}} Tyrannomon.]]

[[folder:Web Comics]]
* Webcomic/{{Poharex}} is one.
* A zombie ''T. rex'' shows up in [[http://www.th3rdworld.com/web-comic/Holiday-Wars/episode/Holiday-Wars-Episode-47 an episode]] of ''Webcomic/HolidayWars''.

* ''Webcomic/PennyArcade'': [[http://www.penny-arcade.com/comic/2007/11/7/ This is what happens]] when Gabe is left to write the comic on his own.
* If there was anyone out there who doubted that ''Webcomic/AxeCop'' is something truly special, it dissipated once [[http://axecop.com/index.php/acask/read/ask_axe_cop_8/ Axe Cop's pet]], Wexter the ''T. rex'', is introduced.
* In ''Webcomic/ElGoonishShive'', Dan's adventuring party is chased by a ''T. rex'' at the end of the [[http://www.egscomics.com/egsnp.php?id=119 "Dan in the MUD"]] storyline.
* King Samrick from ''Webcomic/CharbyTheVampirate'' has a talking ''T. rex'' named Benny, with a another head and mouth hidden inside the first, as his herald.

* ''WebAnimation/HappyTreeFriends'':
** Cro-Marmot gets attacked by a ''T. rex'' in "Dino-Sore Days".
** Disco Bear gets crushed by a ''T. rex'' and ripped apart by a raptor in his Halloween Smoochie.
* The website "[[http://trextrying.tumblr.com/ T. Rex Trying...]]" highlights the numerous problems of having such tiny arms.
* ''WebVideo/LoadingReadyRun'': The title [[http://www.youtube.com/watch?v=TTgUKCrkVoc Dinosaur]].
* Grarrls from Website/{{Neopets}}, which have the distinct ability (shared with Skeiths) to eat any item the user wishes.
* Mutated ''T. rexes'' ([[TheCoconutEffect intentionally misspelled "T-Rex"]] in keeping with [[Toys/LEGODinoAttack its source material]]) are one of the four major breeds of mutant dinosaur enemies in Roleplay/DinoAttackRPG. They have [[FrickinLaserBeams Frickin' Laser]] EyeBeams, [[BreathWeapon breathe nuclear radiation]], and are NighInvulnerable. Several notable Mutant T-Rexes include [[ItMakesSenseInContext one that is disguised as a human to be a spy]], a ''T. rex''/[[DinosaursAreDragons dragon hybrid]], a {{Cyborg}} ''T. rex'', and even [[ScaledUp the main villain's final form]]. Not to mention the several tyrannosaurs who appear and are shown to be ''extremely'' intelligent, having their own society, and a language that can be understood and "translated". There's even one or two that can fully comprehend English.

[[folder:Western Animation]]
* The main villain of ''WesternAnimation/TheLandBeforeTime'' series is Red Claw, the "biggest, meanest, most ferocious Sharptooth of all". Which is a HUGE example of an InformedAbility as Red Claw is probably among the least dangerous Sharpteeth to appear in the entire series (he retreated after having fruit catapulted at him), especially in comparison with the first film's antagonist, who famously killed Littlefoot's mother.
* There was a cartoon called ''[[http://en.wikipedia.org/wiki/The_Adventures_of_T-Rex The Adventures of T-Rex]]'', about a group of anthropomorphic ''T. rex''es that [[AnimalSuperheroes fight crime]]. Yeah.
* Naturally, there is a ''T. rex'' in ''[[ComicBook/XenozoicTales Cadillacs and Dinosaurs]]''
* In ''WesternAnimation/DinoRiders'', BigBad Krulos rides a ''Tyrannosaurus rex'' into battle. In one episode, the Rulons plopped a young ''T. rex'' in the middle of the Valorians' camp and let its parents wreak havoc.
* The BigBad of ''WesternAnimation/{{Dinosaucers}}'' was a ''T. rex'' named "Genghis Rex". Funnily enough, the leader of the heroes was an ''Allosaurus'', the first of many BashBrothers-ish counterparts that make up the cast, and the show also features Teryx, a very rare heroic maniraptor.
* ''WesternAnimation/{{Futurama}}''
** "The Scary Door" segment in ''Bender's Game'' features "the humblest of God's creatures: The ''Tyrannosaurus rex''" taking down alien saucers.
** Fry rides one in a kiddie park in "I Dated a Robot". He even feeds it a live pig (from a food dispenser). It eats his hands.
* Watch ''WesternAnimation/TeenTitans'', ''WesternAnimation/JusticeLeague'', and several other animated series [[Franchise/{{DCAU}} set in the DC universe]] and you'll [[EpilepticTrees eventually come to the conclusion]] that all the [[{{Animorphism}} animal-specific shapeshifters]] had a meeting and decided that ''[[DinosaursAreDragons T. rex]]'' would be their go-to OneWingedAngel equivalent.
* ''WesternAnimation/BatmanTheBraveAndTheBold'' has an episode set in Dinosaur Island. Guess what's the first species Bats and Plastic Man encounter?
* The one and only time-travelling episode of ''WesternAnimation/JonnyQuestTheRealAdventures'' features Jonny and Jessie spending a short time in the late Cretaceous being chased by a ''T. rex'', of course.
* ''WesternAnimation/SchoolHouseRock'' depicts the National Debt as a hungry Godzilla-sized ''Tyrannosaurus'' that sits on Capitol Hill, constantly eating money received from taxpayers. And "Tyrannosaurus Debt" is still growing.
* In ''WesternAnimation/XMen'', Xavier and Magneto find themselves trapped in the Savage Land, an island that contains dinosaurs, among other oddities. The two wind up being chased around by a ''T. rex''.
* T-Bone from ''WesternAnimation/ExtremeDinosaurs'' is an anthropomorpic ''T. rex'' and is the leader of the heroes.
* Because it {{lampshades}} on the idea of [[TeenageMutantSamuraiWombats Secret Hero Mutant Team]], ''WesternAnimation/KungFuDinoPosse'' has one being the leader.
* Tina from ''WesternAnimation/TheAmazingWorldOfGumball''.
* Completely subverted in ''WesternAnimation/DinosaurTrain'' where all of the ''T. rex'' characters are friendly.
* In the ''WesternAnimation/PhineasAndFerb'' episode "It's About Time" (not the only time travel episode, but the only one where they go into prehistoric times), Phineas, Ferb, Candace, and eventually Isabella's entire [[ScoutOut Fireside Girl troop]] go back to 300 million BC and almost get eaten by a ''T. rex''. 300M BC is waaaaaay too early to meet a tyrannosaur, but [[WhereTheHellIsSpringfield Danville]]... ''might'' be in Central North America...
* Tyrannor from ''WesternAnimation/DinkTheLittleDinosaur''.
* ''WesternAnimation/GeneratorRex'' follows the TimeTravel corollary. In the episode "Lions and Lambs", Providence faces off against an EVO with TimeTravel powers. She opens a portal and brings forth, yeah, you guessed it. Our hero, not knowing yet that he's facing a TimeMaster, assumes that what looks like a Tyrant Lizard King is actually an [=EVO=], and tries to [[BroughtDownToNormal Bring It Down To Normal]]. Yeah, that's not going to work, because it's a real [[IncrediblyLamePun Tyrannosaurus, Rex]].
* A ''T. rex'' wearing a wristwatch and sipping tea makes an appearance in one episode of ''WesternAnimation/{{Bonkers}}''.
* One episode of ''WesternAnimation/XiaolinShowdown'' featured a ''T. rex'' that spoke with a British accent.
* In the "Death of the Dinosaurs" episode of ''Albert Asks'', a ''Tyrannosaurus'' shows up and chases after Albert while Zora tries to manipulate the Tempus Fidget to save him. Fortunately for Albert, an ''Albertosaurus'' shows up and battles the ''T. rex'', giving enough time for Zora to pick him up and save him. Surprisingly, the ''Albertosaurus'' manages to win the fight.
* One of the one-time villains of ''WesternAnimation/DarkwingDuck'' is a motorcycle-riding ''Tyrannosaurus'' named Johnny T. Rex.
* ''I'm a Dinosaur'' has a ''Tyrannosaurus'' with a crown... and three fingers.
* ''WesternAnimation/{{Stanley}}'' made an episode dedicated to ''Tyrannosaurus'', which is pretty much the only episode about dinosaurs (not counting the TV movie). Interestingly, the ''T. rex'' in this cartoon shifts from the obsolete tripod stance (without tail-dragging) to the more modern horizontal stance. Too bad it has [[ArtisticLicensePaleontology alligator belly scales, a bendy tail, and the standard three fingers]]. They also state it to be solitary, possibly due to ScienceMarchesOn
* ''WesternAnimation/TheMagicSchoolBus'' has one episode where the class travels back in time and starts hanging out with dinosaurs, except for the most part it's primarily plant eaters. Partially subverted in that when a ''T. rex'' '''does''' appear, it's just taking a nap and upon waking up, turns out to just want a quick meal without too much trouble.
* One episode of ''WesternAnimation/DanVs'' has Dan trying to take down a giant dinosaur that destroyed his car.
* ''WesternAnimation/TimonAndPumbaa'': A ''T. rex'' appeared in the episode "Timon Alone". However, even it is scared of Pumbaa's UnstoppableRage.
* In ''WesternAnimation/TheAngryBeavers'', Dagget brings home a marine park orca that terrorizes him, Norbert, and their friends. At the end, the orca gets eaten by a ''Tyrannosaurus rex'', which Dagget also brought home.
-->'''Norbert:''' Where in the name of DeusExMachina did that ''T. rex'' come from!?
* ''WesternAnimation/{{Ben 10}}'': In "Washington, B.C.", Dr. Animo uses his gadget to bring ''Tyrannosaurus'' bones to life.
* ''WesternAnimation/TheFairlyOddParents'': ''Tyrannosaurus'' appeared in the episodes "The Big Bash" and "Land Before Timmy". Wanda even turned into one in the into of the TV movie ''WesternAnimation/AbraCatastrophe''.
* Surprisingly averted in ''WesternAnimation/TheFlintstones''. ''T. rex'' never shows up at all. That is, until ''The New Fred and Barney Show'' and ''WesternAnimation/TheFlintstoneKids''
** ''Tyrannosaurus'' does make a cameo at the beginning of the made for TV movie ''I Yabba-Dabba Doo''. It is used by the workers at the quarry to grind down huge stones into tiny chunks thanks to its powerful teeth.
* General Galapagos from ''WesternAnimation/EekTheCat''.
* ''WesternAnimation/FamilyGuy'':
** In a CutawayGag, Peter has owned a T. rex named Patches and played fetch with it... only for Patches to bring back a screaming human. Peter tells the dinosaur to repeatedly drop him, and when it does, Peter only remarks "Eww, it's got spit all over it."
** Another scene has a ''T. rex'' preparing to watch internet porn only to find out that his arms were too short to let him masturbate. In a rage, he destroys the computer and storms off, making a random guy sing about the dinosaur.
* In the fifth "Treehouse of Horror" episode from the ''WesternAnimation/TheSimpsons'', when Homer [[ItMakesSenseInContext travels back in time using a toaster]], a big Tyrannosaurus is the first thing to attack him. In a subsequent travel, Homer sneezes on him...and causes the extinction of dinosaurs ([[AndZoidberg and a few Pteranodon]])
--> '''Homer'''': "''This is gonna cost me... ''"
** A resurrected and trained ''T. rex'' with a teddy bear and a sleeping cap appears in "Days of Future Future" where it is told by a grown-up Bart to do a juggling act, which it fails at due its tiny arms and even sheds a tear from it.
* The StopMotionAnimation short ''WesternAnimation/PrehistoricBeast'' features a ''T. rex'' stalking and attacking a ''Monoclonius'' in ancient Alberta (an anachronism, as ''Monoclonius'' was long extinct before ''T. rex'' lived).
* Noah from ''WesternAnimation/ProjectGeeKeR''.
* Tyrannosaurs appear numerous times in ''WesternAnimation/TransformersRescueBots'', starting with "Trex", a bio-mechanical dinosaur designed as a museum exhibit. A Tyrannosaur appears in the flesh in the season 3 opener, "The Land Before Prime", as an escapee from an underground LostWorld. Optimus Prime himself adopts a Tyrannosaurus form after scanning Trex. Optimus Prime's form is somewhat "retro" in design: walking in "kangaroo" stance. The "real" tyrannosaur is more accurately posed and, rather fancifully, has horny protrusions around its eyes. The toy of Optimus in this form is properly stanced.
* ''WesternAnimation/{{Super 4}}'': In the "Origins" four-parter, a ''T. rex'' is terrorizing the village TeamPet Alien is coming from. The newly formed protagonist group manages to lure it away back into the LostWorld it originated from.
* ''WesternAnimation/MiraculousLadybug'': In episode "Animan", the eponymous villain can take the form of any animal. For the final confrontation, he takes the shape of a ''T. rex''. Cat Noir protests that it's cheating, while Ladybug points that, even extinct, a ''T. rex'' is still an animal.
* The ''WesternAnimation/CatDog'' episode "Dem Bones" had Dog [[DinosaurDoggieBone trying to eat the bones of a dinosaur in a natural history museum]]. Guess which species of dinosaur?
* The ''WesternAnimation/GravityFalls'' episode "Land Before Swine" has the gang travelling to an AbandonedMine and discover dinosaurs trapped in tree sap, and naturally ''Tyrannosaurus'' is among them. [[spoiler:One of the sap-preserved ''T. rex'' later gets used as a fist for the Shacktron in the final battle against Bill Cipher.]]
