History Main / TRexpy

The T-Rexpy is usually a generic dinosaur or dinosaur-like monster (occasionally a descendant of ''T. rex'' that [[LivingDinosaurs somehow survived into the modern age]]) but it can also be a fantasy creature like [[DinosaursAreDragons a dragon]], an alien or a mutant. It is typically bipedal, with a bulky body, long tail, relatively short arms, and a massive head with a broad mouth full of sharp teeth. However, it may have extra features that distinguish it from ''T. rex'' while potentially making it even more fearsome, such as horns, spikes, armor-like scales or feathers (which ''T. rex'' may or may not have had). As ''T. rex'''s puny arms are one feature that diminish its badass image, sometimes the T-Rexpy will have longer arms with massive claws instead; however, some portrayals double down on this visual element and may remove the arms altogether to make the creature a fully ArmlessBiped. In the most bizarre examples, it may even have wings. It will typically be at least as large as a real ''T. rex'' was, but there's no upper limit -- some T-Rexpies are {{Kaiju}}-sized.

* ''VideoGame/HorizonZeroDawn'': In-universe. All the [[MechanicalLifeforms machines]] are based on animals, especially extinct megafauna. The most violent and dangerous is the Thunderjaw, which is clearly based on the ''T. rex''. It has jaw-mounted laser cannons, shoulder-mounted explosive disc launchers, and scanning equipment. So the designer wasn't ''too'' worried about artistic accuracy.

* ''Franchise/{{Digimon}}'': The Agumon line is based on bulky, three-fingered ''T. rex''-like dinosaurs. Its most prominent members in this regard are Greymon, a tyrannosaur-like beast with an armored facial mask, and Tyrannomon, a more PrehistoricMonster-like take with giant claws and a row of Godzilla-like spikes down its back.

* ''Film/TheValleyOfGwangi'': Although it's meant to be an allosaur of some kind, the titular Gwangi is so heavily based on ''T. rex'' that even Creator/RayHarryhausen wasn't sure what species it was in the end, often going back and forth between ''Allosaurus'' and ''Tyrannosaurus''. Eventually, in his autobiography ''Ray Harryhausen: An Animated Life'', Harryhausen settled with the idea that it's a hybrid specimen of the two, classifying Gwangi as ''Tyrannosaurus Al''.

* The Quintaglio species in the ''Literature/QuintaglioAscension'' trilogy by Creator/RobertJSawyer are the descendants of small tyrannosaurs, transplanted to an inhabitable moon to escape the extinction of the dinosaurs. The species that did the actual transplanting genetically engineered them to have five fingers, the ability to regenerate severed limbs, and a high intelligence. They also have some peculiarities like muzzles that flush blue when they lie and the ability to rest on their tails, kangaroo-style. There are also actual tyrannosaurs (although probably not rex) they call "blackdeaths" for their solid black coloration.
* The Eaters in ''Son of Man'' by Creator/RobertSilverberg are huge, scaly, bipedal carnivores with oversized heads, dozens of fangs, tiny arms, a long tail . . . and they telepathically inform the main character that they are descended from humans, who genetically engineered themselves into a Tyrannosaurus-like form.
* The apex predators of the underground Antarctic LostWorld in James Rollins' ''Subterranean'' are monotreme mammals that convergently evolved the appearance (and size) of T.rex.

** [[https://sites.google.com/site/worldofserina/the-cryocene-50---75-million-years/tyrant-serins?authuser=0 The tyrant serins]] are enormous flightless apex predators with powerful bone-crushing beaks, wings reduced to vestigial appendages, and tail-like extensions of their pygostyles to balance their immense heads; over time, some species that endure into the next geologic epoch lose their forelimbs altogether. They are mostly adapted for preying on the similarly flightless, elephant-sized serestriders, which they kill with guillotine-like bites to the neck.

* ''VideoGame/{{Temtem}}'': Tyranak is based on a ''T. rex''. While it's not described as aggressive, both of its traits (Intimidator and Frightening) involve striking fear into its enemies, and it learns the attack-lowering technique Roar. Unlike many examples, it has a few feathers; or rather, [[{{Planimal}} leaves]] that ''resemble'' feathers on its neck and tail.

* ''Film/KingKong2005'': The fictional theropod ''Vastatosaurus rex'' is designed to resemble an evolved Tyrannosaurid with notable similarities to ''Tyrannosaurus'' itself. There are some obvious differences: instead of a prominent overbite, the V. rex has overlapping teeth like a crocodile, as well as hardened body armor and three fingers on its hands. They're also much larger due to island gigantism, with almost twice the body mass of a ''Tyrannosaurus'' (16 tons vs 9). All of these differences were very intentional, rather than the filmmakers just not caring, and particularly allude to the ambiguous identity of the theropod that Kong fought in the original 1933 film--the three-fingered hand in particular is a common mistake, when tyrannosaurs famously have only two.

* ''[[Series/TsuburayaDinosaurTrilogy Series/DinosaurGreatWarIzenborg]]'', the first antagonist is a ''T. rex''-like Kaiju known as Uuru.

* ''TabletopGame/{{Warhammer}}'' has the Carnosaur, one of the many kinds of dinosaur/pterosaur-like megafauna native to the jungles of Lustria. They look like exaggerated ''Tyrannosaurus'' (with a smidgen of RaptorAttack) and are one of the most prized war mounts of the [[LizardFolk Lizardmen]].

* ''Moon-Boy and Devil Dinosaur'' and ''ComicBook/MoonGirlAndDevilDinosaur'': The eponymous Devil Dinosaur looks like a ''T. rex'', but is larger, stronger, more intelligent (although not human-level intelligent), and colored bright red. Despite his appearance, he's never explicitly identified as a ''T. rex''. He is sometimes said to come from an alternate universe called Dinosaur World (Earth-78411), where it can be assumed dinosaurs continued to evolve after their extinction in most worlds.
