* ''VideoGame/XenobladeChronicles1'' and ''VideoGame/XenobladeChronicles2'' have the Sauros enemies. In the first game, they look vaguely draconic, can be found at ''very'' high levels in Makna Forest, and have a Talent Art where they eat a party member and inflict Instant Death on them. In the second game, they're mostly found in Temperantia, but a particularly nasty one can be seen roaming Gormott in the very early game and will happily one-shot the party if it sees them. Another monster in ''[=XC2=]'', the Tyrannotitan Kurodil, is the strongest regular OptionalBoss in the game and looks somewhat dinosaurian, but it's more of a NotZilla despite its naming.

* ''WebOriginal/HamstersParadise'': The original draft of the project had a species of large carnivorous hamster descendants resembling theropods evolve into a muscular nine-foot-tall predator called a tyrat which, as the name suggests, converged heavily on a ''Tyrannosaurus rex'' in niche and appearance.
** In the current canon, the apex predator of North Westerna in the Middle Temperocene is the pterowrex, a large, vaguely dinosaur-like biped that hunts mammoth-like herbivores called maustodons. Curiously, this is a case of BizarreSexualDimorphism, as only the females are are T-Rexpy's: the male is a far smaller and flying species more akin to storks or azhdarchid pterosaurs.

* The Catastrophic Fraggon from ''WebOriginal/{{Amphiterra}}'' is a descendant of frog-like amphibians that fills the role of Tyrannosaurus, being a deadly apex predator. It’s even the same size as a ''T.rex''!

* Taken up to eleven in ''ComicBook/OldManLogan'', which featured a T-Rex bonded with the Venom symbiote.

In the first game, they look vaguely draconic, can be found at ''very'' high levels in Makna Forest, and have a Talent Art where they eat a party member and inflict Instant Death on them. In the second game, they're mostly found in Temperantia, but a particularly nasty one can be seen roaming Gormott in the very early game and will happily one-shot the party if it sees them.

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. Most T-Rexpies are outwardly reptilian, but some have feathers, whether sparse or body-wide, and may even be specifically giant predatory birds. More unusual examples of this trope, such as explicitly mammalian or robotic T-Rexpies, also exist.

* ''VideoGame/FossilFighters'', a dinosaur-based {{mon}}s series, features over half a dozen versions of ''T. rex'' as usable Vivosaurs, and they're all substantially different from the real thing due to their revival process. The basic version, known as T-Rex Sue in ''Fossil Fighters: Frontier'', has red-black striped skin and mohawk-like fur running down its body, and is [[PlayingWithFire Fire-element]]. Others include a [[SuperMode Super Evolved]] form that stands upright like how ''T. rex'' was originally speculated to stand, [[DemBones Boneysaur]] and [[NightOfTheLivingMooks Zombiesaur]] versions, and the [[BlowYouAway Air-element]] T-Rex Stan. Tellingly, [[spoiler:when actual ''T. rex'' appear late in ''Frontier'', the contrast of them being NonElemental with realistic brown skin is apparent]].

''UsefulNotes/TyrannosaurusRex'' is [[KingOfTheDinosaurs one of the most famous, fearsome and majestic creatures]] that ever lived on Earth. In a story featuring giant monsters, ''T. rex'' is an obvious choice. However, some authors just find that ''T. rex'' itself is a little ''too'' cliché and want something more original, or that using a real dinosaur species just wouldn't fit the setting. So instead of using the tyrant lizard king itself, they show an original creature that obviously resembles it, resulting in something of an {{Expy}} of ''T. rex'' -- a T-Rexpy.

SubTrope of PrehistoricAnimalAnalogue, when other extinct animals are used for fictional designs. For depictions of ''T. rex'' and T-Rexpies being portrayed as noble, dominant or majestic beasts, see KingOfTheDinosaurs.

** The Bahrag are twin [[KingOfTheDinosaurs queens]] of Bohrok Swarm, and they share more design cues with the ''T. rex'' than the Bohrok's beetle-like appearance, such as a giant set of jaws with sharp teeth, a therapod stance, and tiny two-fingered forelimbs.

* ''VideoGame/MonsterHunter'': Many monsters are based on ''T. rex''. Most are Brute Wyverns, a class of monsters characterized by bipedal stances, short forelegs, great physical bulk and strength, and heavy heads with strong jaws.

** In the third generation there's Deviljho, who debuts in ''VideoGame/MonsterHunter3Tri'', and its variant Savage Deviljho, who debuts in the expansion ''Monster Hunter 3 Ultimate''. Both monsters are Brute Wyverns with small arms and large heads, and extremely aggressive temperaments. They're also prone to repeatedly hunt preys to eat.

* ''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'' (17 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.

** The ''Zoids'' franchise has many, many other Tyrannosaur Zoids, such as its former mascot, the Gojulas, but these tend to be {{NotZilla}}s rather than proper tyrannosaurs.

* ''Series/UltramanNeos'': The Rock Eaters are a race of Kaiju that resemble an upright red ''T. rex''. They fight a KingKongCopy named King Bamos, to further the resemblances.

* In Creator/{{Filmation}}'s ''[[WesternAnimation/FlashGordon1979 Flash Gordon]],'' some of the assorted giant monsters running around Mongo are of this type. Episode Two features a couple of them getting in a fight with each other.

** In the second generation there's Tigrex, the flagship monster of ''Monster Hunter Freedom 2'', who has a ''T. rex''-like head and reputation, but is actually a Flying Wyvern.
** In the third generation there's Deviljho, who debuts in ''Monster Hunter Tri'', and its variant Savage Deviljho, who debuts in ''Monster Hunter Tri Ultimate''. Both monsters are Brute Wyverns with small arms and large heads, and extremely aggressive temperaments.
** In the fourth generation there's Glavenus, one of the flagship monsters of ''Monster Hunter Generations''. It has ''T. rex''-like traits while also drawing some others from ''Carnotaurus''. It also has a [[BewareMyStingerTail massive blade on the end of it's tail]], a firey spit, and the ability to combine the two by superheating the blade in its mouth. ''Monster Hunter World: Iceborne''(more on that below) also provides a variant living in the [[ElephantGraveyard Rotten Vale]] that secretes an acid from the tail that it uses to hone the blade.

* ''VideoGame/XenobladeChronicles1'' and [[VideoGame/XenobladeChronicles2 its sequel]] have the Sauros enemies. In the first game, they look vaguely draconic, can be found at ''very'' high levels in Makna Forest, and have a Talent Art where they eat a party member and inflict Instant Death on them. In the second game, they're mostly found in Temperantia, but a particularly nasty one can be seen roaming Gormott in the very early game and will happily one-shot the party if it sees them. Another monster in ''[=XC2=]'', the Tyrannotitan Kurodil, is the strongest regular BonusBoss in the game and looks somewhat dinosaurian, but it's more of a NotZilla despite its naming.

* ''VideoGame/{{Temtem}}'': Tyranak is based on a ''T. rex'', and is the last surviving relic of a pre-human past according to the Tempedia. 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.

For depictions of ''T. rex'' and T-Rexpies being portrayed as noble, dominant or majestic beasts, see KingOfTheDinosaurs.

* ''TabletopGame/SmashUp'' has the King Rex of the Dinosaur faction, which highly resembles a 100 ft tall Tyrannosaurus and has a power of '7', the strongest base power in the game that comes without a drawback.[[note]]Only the Elder Thing is more powerful, but you have to destroy two of your own cards to play it[[/note]]

Sometimes these creatures will be presented as the FantasticFaunaCounterpart of ''T. rex''. See also {{Whateversaurus}}, PrehistoricMonster and {{Notzilla}}.

* ''Franchise/{{Godzilla}}'' is inspired by a number of different dinosaurs, but he takes a large number of cues from ''T. rex'', being a bipedal, bulky, long-tailed monster with sharp teeth and claws.

** In the fourth generation there's Glavenus, one of the flagship monsters of ''Monster Hunter Generations''. It has ''T. rex''-like traits while also drawing some others from ''Carnotaurus''.

* The Catastrophic Fraggon from ''WebOriginal/Amphiterra'' is a descendant of frog-like amphibians that fills the role of Tyrannosaurus, being a deadly apex predator. It’s even the same size as a ''T.rex''!
