History Characters / JurassicParkTyrannosaurus

* WhatHappenedToTheMouse: It's unknown what happened to them after the events of ''Film/TheLostWorldJurassicPark''. [[spoiler:''WesternAnimation/JurassicWorldCampCretaceous'' has only confirmed that besides Rexy, Big Eatie and Little Eatie are the only known surviving ''Tyrannosauruses'' from Isla Sorna. ''Dominion'' reveals that the Buck and Doe are still alive, and that they were taken to the [=BioSyn=] valley. The baby's fate, however, is still uncertain]].

* UnknownCharacter: Little Eatie’s father, he is never seen or even mentioned and so his existence is only inferred because Little Eatie is Big Eatie’s daughter, meaning Big Eatie had to have a mated with a male prior to being relocated to Mantahcorp Island since we have no indication that ''Tyrannosauruses'', like the Scorpius rex and Blue in '' Film/JurassicWorldDominion'', have the ability to reproduce via Parthogenesis.

** While the skeleton is mostly accurate, they are shrink-wrapped with a conservative amount of fat and muscle tissue, with many of the fenestrae in the skull and features of the skeleton clearly visible.[[note]]While the topic of feathers is debated, given the position within coelurosauria and many of its basal relatives possess feathers, they probably should have some type of sparse feathering on their backs, if nothing else.[[/note]]. Real ''T. rex'' [[https://www.youtube.com/watch?v=j1rjEe9ERfY would have been]] bulky and sported lips covering their teeth. ''T.rex'' also had forward-facing eyes in real life, and while these rexes don't have eyes completely on the sides of their head like most large theropods, they're still a little too off to the side compared to the real animal. They're also shown with an arching ridge over each eye, which isn't ''totally'' inaccurate but somewhat oversimplified compared to the rather complex series of bony bosses that adorned the cranial region of a real ''Tyrannosaurus'' skull. The famously powerful bite forces of ''Tyrannosaurus'' appear to be downplayed, as anything that gets in the jaws of a ''T. rex'' would either shrug them off (if they are large) and need a few more bites to be killed (if they are small). Granted, it is possible the ''T. rex'' were just not biting down hard enough (as Rexy was able to kill a ''Tarbosaurus'' with a single bite to the neck).

* MysteriousPast: Aside from Mae telling the kids that Big Eatie and Little Eatie are a mother and daughter originally from Isla Sorna there is not much further information about them, how old they are, when they were taken from Sorna, what happened to Little Eatie's father and how many other ''Tyrannosauruses'' from Sorna are still alive.

* ThereIsAnother: The existence of Big Eatie and Little Eatie confirms that Rexy is not yet the last of her kind. [[spoiler: This is even more the case by the time of ''Dominion'' as both the Buck and Doe are confirmed to be alive and have formed a family unit with Rexy in the Biosyn valley, meaning that globally there are a total of five known surviving ''Tyrannosauruses'', Three in Italy and two on Mantahcorp Island with Junior and at least another three or four from Ingen’s original seven unaccounted for.]]
* VagueAge: Neither Big Eatie nor Little Eatie is given exact ages nor an indication of when they were each born (while a natural tyrannosaur their size would have to be at least 13 years old, the cloning process causes rapid maturity with Rexy reaching her larger adult size within 5 years). Little Eatie should still be quite young and the fact that Big Eatie is her mother means that she is at least a second or third generation ''Tyrannosaurus'' which would place her under 23 years old, but it's unknown if Big Eatie is one of Ingen’s original seven ''Tyrannosauruses'' or a hatchling from a later generation herself. The former seems more unlikely as she did not live a partially captive life or in an environment without direct competition as Rexy did.

* GenderBender: This applies to the Buck. Since Rexy, the Buck and the Doe (and potentially Big Eatie, whose exact age is unspecified) are the only known ''T. rexes'' old enough to have been from Ingen’s original generation of seven cloned ''Tyrannosaurs'', with the Buck being the only male out of the trio (or quartet). Meaning the Buck must have originally been female before undergoing the gender-swapping process prior to the events of ''The Lost World'' since all of Ingen’s animals were originally cloned as females.

* BadassFamily: They're a family of ''Tyrannosaurus rexes'', after all.[[spoiler: ''Dominion'' implies Rexy, the ''Tyrannosaurus'' from Nublar, joined in sometime after her arrival to [=Biosyn=] valley or her battle with the ''Giganotasaurus''.]]

* {{Super Persistent Predator}}s: Even after their baby has been given back to them, the parents don't go away and keep chasing the humans. Perhaps they found Eddie very tasty and want more...

** In fairness, it's stated that the ''rexes'' still see the remaining humans as intruders upon their established territory and that the kidnapping of their infant caused them to extend that territory wider. Plus, the infant's blood on Sarah's jacket ends up attracting them due to their strong sense of smell.

* DarkerAndEdgier: The parents are downright scarier than Rexy. They sound angrier as they are, they wouldn't leave the humans alone, and they caused more deaths than Rexy did.

* EvilCounterpart: While not evil, Buck is this to Ian, in that they are both highly protective of their children. The scene in the RV is a good example. When Sarah points out that her theories on ''T. rex's'' parental instincts are correct, Ian panics because he realized what ''he'' [[PapaWolf would do if someone tried to hurt his daughter.]]

* SuperPersistentPredator: Despite having a whole carcass in front of it, the ''rex'' decides that chasing and attacking the humans that stumble upon it is a much more interesting thing to do. This causes its death as while chasing them they blunder into the ''Spinosaurus''. Could be ''partially'' HandWaved assuming it mistook the humans for scavengers, but even then it should've stopped chasing them long before it actually did.

** In ''Jurassic World'', Rexy shows that she's a true GeniusBruiser when she thrashes the ''Indominus'' by smashing it into buildings, learns the larger theropod's attack pattern, and throwing it close to the ''Mosasaurus'' pool (even taking a few deliberate steps back) to finish it off.

** Rexy "tests" whether or not the electric fence is on with her claws before breaking through it.

** Rexy, more than once, has shown that she knowns how to throw objects to cause damage. This is ''very rare'' in the animal kingdom. The only animals that can do this (with something other than a body part or fluid) are all highly intelligent, like elephants, orcas, a few birds, and of course, ''primates''.

* ItCanThink: To a lesser extent than the raptors (and how smart they probably were in real life), but the ''T. rexes'' are shown to have intellect beyond basic instinct.
** Rexy "tests" whether or not the electric fence is on with her claws before breaking through it.

** Buck and Doe are smart enough to sneak into InGen's camp at night ''without anyone but Ian and Sarah noticing''. Buck also doesn't attack Sarah and Kelly in their tent because it smelled its baby's blood close to them, and was trying to figure out if its baby was in the tent.

* AdaptationalDumbass: In an interesting twist, from the first novel ''Tyrannosaurus'' was described as an unthinking, instinct-driven super predator who was ultimately less scary up close than the highly intelligent, reasoning ''Velociraptor''. However science moves on and it's now being argued that dromaeosaurs were fairly unremarkable in terms of their intelligence while some researchers are arguing ''Tyrannosaurus'' may have had comparable to higher order primates like baboons. As the franchise has continued this has been dialed back somewhat as the focus on Rexy as a character has resulted in her developing a distinct personality while coming across as more intelligent as a result.
