* ''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 tyrannosaurids famously have only two.

* ''WesternAnimation/CarsontheRoad'' has the Tyranamissiasaurus rex and the Spinocrankshaftorex from the episode where Lightning McQueen visit a dinosaur park. Both are robotic dinosaurs sporting tractor tires instead of legs, car-shaped faces, and smokestack-like nose-horns.

* ''Fanfic/VowOfNudity'': The demonsaurus, essentially a T-Rex covered in spikes, is the alpha predator in the abyssal swamps, and its den is littered with half-eaten corpses of all the other creatures Haara and Fiora had encountered to that point.

* ''{{WesternAnimation/Dinotrux}}'' has the Tyrannosaurus Trux [[note]]Because "wrecks" would've sounded way too obvious[[/note]], robotic T. rex-like dinotrux resembling excavators featuring a head resembling its bucket, treads instead of legs, and a wrecking ball for a tail.

-->''It looked like one of the great carnivorous dinosaurs of the Cretaceous days. Its forearms were small, its tail was thickened for balance, and its hind legs were awesomely powerful machines of muscle and bone. Its incisors had developed into ferocious slashing weapons, to be deployed by thrusts of the heavy head. The mouse-raptor was a land shark, like a tyrannosaur, a body design rediscovered and made devastatingly effective.''

** The iconic bauplan of a bulky, big-headed predator with short arms also evolved independently in several other theropod lineages outside of the tyrannosaurs (with abelisaurids and carcharodontosaurids being perhaps the most notable examples).

* In the sci-fi season of ''WesternAnimation/{{Archer}}'', the crew crashes on a planet and are threatened by a tyrannosaurus-like alien adorned with rocky spikes along its spine and the ability to perfectly camouflage itself, similar to the titular creature from Predator.

* ''Tyrannosaurus rex'' was the largest of its family, but it was far from the only type of tyrannosaur. Belonging to the Tyrannosauridae family. ''T.rex'' was one of roughly a dozen known species in a family which all shared some very similar traits; enough a layperson could certainly mistake its relatives for ''T.rex'' itself at a glance if they aren't familiar with the differences. Tyrannosauridae are all fairly large bodied theropods with short arms, two-fingered hands, and large-skulled predators found across North America and Asia. Of the group, ''Tarbosaurus'' and ''Zhuchengtyrannus'' most resemble ''T.rex'' as its closest relatives.

* ''WesternAnimation/ABugsLife'' features a bird as a secondary antagonist -- it plays this role quite well, being [[GiantFlyer significantly larger than all the insect characters]], having a GiantFootOfStomping and a song that, from the bugs' perspective, resembles a MightyRoar. Likely pretty appropriate, as birds are themselves theropod dinosaurs.

* ''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.

** For decades, scientists tried enforcing this by arguing whether or not ''Daspletosaurus'' was ''T. rex's'' direct ancestor through anagenesis (which is very controversial as a concept). There have also been many scientists who have argued that ''Daspletosaurus'' was actually an early species of ''T. rex'', rather than its own genus. This was before later species like ''Lythronax'' and ''Teratophoneus'' were discovered, both of which were found to be much more similar to T. rex, while also being older than ''Daspletosaurus''. Close inspection of the three different species shows that Daspletosaurus only looked similar to ''T. rex'' superficially, which was likely a result of convergent evolution. If ''T. rex'' was a comparable to a bear, ''Daspletosaurus'' was the equivalent of a wolverine. Still, there are some who still argue the anagenesis hypothesis.

* ''WebOriginal/{{Serina}}'': On a number of occasions, some of the descendants of the canaries become adapted for life as large, flightless predators of megafauna. In the earlier periods of Serina's history, where the original avian form is still relatively unmodified, this results in forms reminiscent of the tyrannosaurs.

* ''WebOriginal/{{Amphiterra}}'': The Catastrophic Fraggon 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''.

* ''WebOriginal/{{Snaiad}}'': The See-Rex is one of these, right down to the name. It's a giant, bipedal theropod-like predator inhabiting a LostWorld of vaguely dinosaur-like creatures.
