10[[folder:''Tyrannosaurus'' in general]]
11* TheAce: ''Tyrannosaurus'' is often depicted in the series as easily the most capable and majestic dinosaur, or at least second only to the ''Velociraptor''. With a massive size, intimidating expressions, incredible strength, adequate speed, and is well-equipped to deal with nearly everything that can get in its way, ''Tyrannosaurus'' is an ace compared to nearly every other dinosaur it could compete against. While the ''Velociraptor'' has the Tyrant Lizard King beaten in intelligence and ferocity, the ''T. rex'' still has an advantage in a direct fight.
12* 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 smarts 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.
13* AdaptationalWimp: Very {{downplayed|Trope}}; ''Tyrannosaurus'' in the series is treated as an apex predator and a force of nature that is nearly unparalleled by any animal. That said, it has one weakness, that being its eyesight is limited to only being able to see objects that move and thus cannot perceive anything that is motionless. In reality, ''Tyrannosaurus'' is determined to have excellent eyesight according to paleontologists, arguably among the very best in the animal kingdom, more accurately. Even so, this slight disability doesn't stop ''T. rexes'' from being dreaded by anybody who dares to encounter them.
14* ArtisticLicensePaleontology:
15** 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 brow 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).
16** The first film depicts ''Tyrannosaurus'' as being able to reach speeds of at least thirty-two miles an hour. While some earlier speed estimates had higher-end top speeds, depicting such a massive animal being fast enough to keep pace with a speeding car was absurdly optimistic, even back then. Most modern estimates put an adult ''T. rex'''s top speed at only around 15 to 11 miles per hour (although juveniles would've been much faster). So while ''T. rex'' could probably outrun the average human on foot, an Olympic athlete is still faster, so it definitely couldn't catch up to a vehicle.
17** The series has infamously depicted ''Tyrannosaurus'' as being a LivingMotionDetector, only seeing its prey if it's moving (although it was quietly dropped by ''Jurassic World''). This is of course absolute malarkey and isn't based on any fact that ever existed. Studies of ''T. rex'' vision have instead shown the animal likely had superb vision, even greater than the acuity of modern birds-of-prey (and even if somehow they couldn't ''see'' their prey, they could obviously still ''smell'' them, because tyrannosaurs also had exceptional olfactory capabilities).
18** Another minor error regarding the eyes are their size; the eyeballs as depicted in the films are way too big. Real ''Tyrannosaurus'' would've had eyeballs about three inches wide at most, and only about half of that would've been visible. Although obviously still much larger than a human's eyes, on an animal larger than an elephant holding its head some fifteen feet off the ground, it would've appeared positively beady-eyed.
19** The series depicts ''Tyrannosaurus'' as having thunderous steps as a way to herald its arrival menacingly (unless it's plot-convenient for them to suddenly be stealthy). FridgeLogic ensues here: why would a predator have footsteps loud enough to be heard and felt as it approaches? Indeed, studies have indicated that it's likely ''Tyrannosaurus'' and other large predatory theropods had fatty tissue on the undersides of their feet to dampen their footfalls. There are thankfully some scenes where the rexes are capable of muffling their footsteps, indicating that they can control how loud their steps are.
20** The ''Tyrannosaurus'' is depicted with a MightyRoar and basically codified the idea of ''T. rex'' having a thunderous scream, but there was never any real evidence for it, besides [[RuleOfCool being cool]]. Most modern studies on dinosaur vocalizations suggest tyrannosaurs could not roar, but may have bellowed or hissed like a crocodilian.
21* BadVibrations: A ''Tyrannosaurus'' is often heralded by the thunderous footsteps they make, a low boom with still water rippling in a rhythmic beat. Despite being a very bone-chilling sound to hear, it's far better than their alternative introduction, [[StealthyColossus a sudden ambush out of nowhere]] and a quick trip down its bone-crushing jaws.
22* {{Determinator}}: A ''Tyrannosaurus'' is a very determined animal and often doesn't give up on what actions it wants to take part in. In fact, the only times it stopped was when it chased away a rescue Jeep or when an [=InGen=] worker was able to escape via a helicopter, though around that point, Rexy was more interested in driving them out of her territory rather than wanting to eat them. For extra points, their own offspring can be a sensitive spot for them, and they will go to the ends of the Earth if it means finding their young and punishing whoever threatened or kidnapped them.
23* TheDreaded: Discounting the raptors, ''T. rex'' is unquestionably among the most dangerous and frightening dinosaurs in the series, with the cast and most other dinosaurs expressing panic and dread at the very thought of having to encounter or think about the Tyrant Lizard King. Its reputation is well-earned, considering ''Tyrannosaurus'' can turn out to be quite persistent and resilient in its pursuit of either prey or whatever provoked the dinosaur first.
24* GoodParents: ''T. rexes'' are often shown to be attentive and caring parents for their young, which is best shown with the tyrannosaur family in ''Film/TheLostWorldJurassicPark'' and Big Eatie and Little Eatie in ''WesternAnimation/JurassicWorldCampCretaceous''.
25* HandicappedBadass: The fact that the in-universe species vision is based on movement does not stop them from being fearsome and competent apex predators.
26* ItCanThink: To a lesser extent than the raptors, but the ''T. rexes'' are shown to have intellect beyond basic instinct.
27** Rexy "tests" whether or not the electric fence is on with her claws before breaking through it. It's implied she does this every time she feeds near the fence, as it's very unlikely this was spontaneous.
28** Rexy, more than once, has shown that she knows 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''.
29** The Tyrannosaurs are able to muffle their footsteps when they want to be stealthy, as multiple scenes of them sneaking out from nowhere show.
30** Buck and Doe are smart enough to sneak into In-Gen's camp at night ''without anyone but Ian and Sarah noticing''. Buck does this again at the end when he sneaks up on Ludlow. 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.
31** Buck also stays completely quiet while stuck in the cargo hold of the ship transporting him, only smashing out the moment the doors started to open. He knew that no one was aware he was stuck down there, and so patiently waited for someone to open the doors. This also implies Buck had figured out how the cargo door worked when he watched it trap him.
32** 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. Not only that but she's also able to recognize that Blue is more of an ally instead of an enemy in this fight and once it's over, strides off without attacking the raptor.
33* LightningBruiser: ''Tyrannosaurus'' is a massive carnivorous dinosaur with what is arguably the most powerful bite of any land animal that has ever existed. For its size, it's also quite fast and reactive.
34* LivingMotionDetector: In both film and novel, ''Tyrannosaurus'' is often depicted as having a form of impairment with its eyesight, namely that it can not perceive motionless objects and sightings. However, with modern science and paleontology having determined that the animal has one of the best eyesights of any animal, this comes across as a form of AdaptationalWimp, but this doesn't stop ''Tyrannosaurus'' from being a feared dinosaur.
35* MightyRoar: It boasts one of the most iconic in film history, and has even managed to find its way into all sorts of DinosaurMedia. A ''T. rex'''s roar in the series is made out of a baby elephant's call mixed with that of a tiger and an alligator, with the breath being taken from a whale's blow. For the record, [[ArtisticLicensePaleontology it's probably unlikely]] the real-life ''Tyrannosaurus'' had a roar as depicted in the films.
36* NoisyNature: ''Tyrannosaurus'' makes a lot of roars and stomping sounds throughout the series. Heck, they can even be heard at a faraway distance, and they don't even need to be shown even once.
37* NonMaliciousMonster: Unlike the ''Velociraptors'' that are mostly portrayed as uber-territorial and savage murder machines in the novels and the first two films, the ''T. rex'' is mainly shown to mind its own business and doesn't really care about anything else. It only targets its quarry if it's hungry or provoked.
38* StrongAsTheyNeedToBe: The speed of the Tyrannosaurus usually varies depending on what is convenient for the plot, sometimes they can chase a car and in other cases non-athletic humans can run away from them.
39* TerrifyingTyrannosaur: ZigZagged with ''Tyrannosaurus'' in the series. Its novel counterpart, as well as film versions on some occasions, portray the dinosaur as a ferocious, territorial animal that asserts itself as a dominant predator that few, namely the ''[[SavageSpinosaurs Spinosaurus]]'' and the ''[[TRexpy Indominus]]'', can hope to threaten. On the other hand, ''Tyrannosaurus'' in the films is shown in a more regal and triumphant fashion whilst retaining its nature as a predatory beast, with Rexy being seen as a loose [[AntiHero Anti-Heroine]] at best.

45!!''Tyrannosaurus rex'' ("Rexy")
46A dinosaur that lived in North America during the Late Cretaceous period around 68-65 million years ago.
47----
48* AmbiguousSituation: Via {{retcon}} from the sequel ''Literature/TheLostWorld1995''. In the original novel, Rexy's inability to see motionless objects is theorized by Grant to be a natural trait of the species based on paleontological findings at the time. But in the sequel novel, it's mentioned that Grant proposed an alternative theory that torrential downpour can confuse a ''T. rex'' because it's not used to a wet climate, which just so happens to be the weather condition during the breakout. Both theories are derided by Dr. Levine, who indirectly suggests that Rexy wasn't hungry when it encountered Grant. Suffice it to say, no one knows why Grant wasn't killed that night, although Rexy is shown eating a goat in its first appearance.
49* AxCrazy: Both of the cloned tyrannosaurs are excessively brutal in the amount of damage and kills they commit. For specifics, the adult has a sadistic tendency of stalking and hunting Alan and the kids whereas the juvenile seems to take her time toying around with Ed Regis before mauling him to death.
50* CreepyChild: While being a predator is to be expected, the way the juvenile tyrannosaur reacts to Ed Regis is very unnerving because she initially ''doesn't'' act predatory towards him. It actually plays around with him for a while, which makes it all the more frightening when it does attack and kill Regis.
51* DiskOneFinalBoss: The novel makes it seem that Rexy is the [[BigBad main dinosaur antagonist of the story]], as her rampage cause devastation across the park and she's hunting down Grant and the kids. But then she succumbs to the tranquilizers shot by Muldoon before she has a chance to reach the Visitor Center; shortly after her sedation, the park's power shuts down and it's revealed that all of the electric fences have been off for hours. It's then the readers realize that the ''Velociraptors'', [[TheDreaded regarded as even more dangerous]] than the ''T. rex'', are the true dinosaur antagonists of the novel.
52* TheDreaded: Well, this ''is'' a ''T. rex'' we're talking about after all. Rexy's presence scares the living daylights out of everybody, human or dinosaur, and the only option upon encountering one is RunOrDie. Unless you have a hefty amount of tranquilizers of course.
53* EvilSmellsBad: Rexy's smell and habits are presented in nauseating detail. She is described as smelling like a garbage dump and her tongue stinks of urine. While asleep, she's covered in buzzing flies and lets out a disgusting belch after eating a dead hadrosaur.
54* TheHeavy: Aside from the raptors, Rexy causes the most trouble for the park. She breaks into several enclosures to eat the dinosaurs living there, forcing the park staff to focus all of their attention on her (and ignoring other issues like auxiliary power), and she hunts Grant and the kids as they try to make their way back to the Visitor Center.
55* InSeriesNickname: Robert Muldoon is the one who calls the adult ''T. rex'' "Rexy."
56* LightningBruiser: Rexy is powerful enough to bring down a fully grown ''Apatosaurus'' and she can run incredibly fast, almost catching up to a gas-powered Jeep.
57* LivingMotionDetector: Rexy's vision is based on movement. A fortunate trait for the scared-stiff Grant when he finds himself completely exposed before the beast. However, the ''T. rex'' family on Isla Sorna can see motionless figures just fine, as [[EatenAlive poor George Baselton finds out]].
58** Worth noting that the one instance in the first book is made a little more plausible by the circumstances: at night, under pouring rain interfering with Rexy's senses of smell and vision, with Grant standing right by a car that she could have trouble distinguishing him from. And at a time where she had recently gotten out of her enclosure and was probably more confused by her new environment than hungry.
59* NotSoHarmlessVillain: The juvenile ''rex''; while it appears less of a threat than the adult and not quite steady on its feet yet, [[spoiler:it actually succeeds at killing a human, unlike the adult]].
60* OverlyLongTongue: She has one that she attempts to snatch Tim with when he is hiding out of reach.
61* RedIsViolent: Her species' primary color here is brick red. And she follows Grant and the kids to no end.
62* ReptilesAreAbhorrent: Her reptilian qualities are really played up.
63* RoarBeforeBeating: Rexy often roars at her potential prey before going for the kill, likely to make up for her motion-based vision impairment.
64* {{Sadist}}: The adult and juvenile in Isla Nublar show shades of this, though it's not to the same levels the ''Velociraptors'' exhibit. Both like to take their time in killing human prey, but their methods differ; the adult constantly hounds Alan and the kids and keeps itself sheltered until the trio either feels they're safe or have outrun the predator, after which Rexy shows up unexpectedly. The juvenile decides to toy around with Ed Regis partly out of amusement and curiosity. For a while, it seems the juvenile tyrannosaur would be somewhat docile towards Regis before lunging for the kill.
65* ScaryTeeth: To be expected from a dinosaur with teeth like ''steak knives''.
66* SheIsTheKing: Even more so than the films. While Rexy's gender in the films is emphasized as female, the novel often refers to Rexy as a male, which is {{lampshaded}} by John Arnold during the tour of the control room.
67* SuperPersistentPredator: Unlike in the film, Rexy is clearly hunting down Grant's group for the majority of the novel, particularly when they try to reach civilization through the river system. She immediately disregards her freshly killed hadrosaur and goes after Grant and the kids in the lagoon, despite the hadrosaur carcass providing her with enough meat to keep her occupied for hours. She even waits for them at the base of the waterfall with jaws wide open, hoping for the humans to fall into her mouth. Ironically, unlike the film version, this ''rex'' fails to actually eat any humans (although she does [[spoiler:lethally injure Ian Malcolm; however, [[OnlyMostlyDead he got better]]]]); it's the juvenile ''rex'' who [[spoiler:devours Ed Regis]].
68* TerrifyingTyrannosaur: Rexy is the crowned attraction of the park and the most dangerous dinosaur on [[ExactWords public]] display, so much so that the park staff prioritizes subduing the animal alive and unharmed rather than checking to see if they're running on main power or if the raptors are still in their holding pen. She spends most of the novel as a constant, terrifying threat to Grant and the kids as they make their way to the Visitor Center through the park, stalking them from a distance before attempting an ambush time and time again.
69* TongueTrauma: The adult is hit with tranquilizers that only start to take effect an hour later, as she's using her long tongue to pull Tim into her mouth. It collapses and falls asleep right then and there, and the massive teeth clamp right down on her tongue, with the text emphasizing the thick, red blood now bubbling out.
70* UncertainDoom: Well, more like most definitely doomed but the circumstances are unknown. Did Rexy die from the napalm bombing at the end of the story, or did she already drown in the pool she's in after being tranquilized by Muldoon?
71* UnwittingInstigatorOfDoom: Her rampage across the park distracts the entire Jurassic Park staff from noticing that they've been running on auxiliary power the whole time, thus causing a power failure that allows [[TheDreaded the raptors]] to break free. Additionally, her hunting of Grant and the kids has forced them to take the river route, which has no motion sensors to signal back to the control room.

88An old ''Tyrannosaurus rex'' and the face of Jurassic World; she was one of the dinosaurs who escaped during the initial disaster at Jurassic Park and is now relocated to Jurassic World as something of a mascot. Queen of Jurassic Park and World--a title definitely earned and ''not'' just given. Following the fall of Jurassic World, she retook her place at the top of the food chain before the destruction of the island resulted in her being released into the wilds in the western United States.
89----
90* AccidentalHero: Rexy is a superpredator only interested in feeding or defending herself and her territory, but she has a long history of unintentionally pulling people's butts out of the fire.
91** In ''Jurassic Park'', her timely attack on [[spoiler:the two surviving raptors saves Alan, Ellie, Lex, and Tim]].
92** Decades later in ''Jurassic World'', she had no idea that the big predator intruding on her territory was a sadistic monster, but the ''Indominus'' would have killed the heroes without her unwitting aid.
93** A few weeks later in ''Camp Cretaceous'', she would chase off [[spoiler:trophy hunters Mitch and Tiffany]] from Main Street, where they were holding Darius and Sammy hostage, and would later [[spoiler:[[JustDesserts eat one of the hunters]] when they became [[HoistByHisOwnPetard caught in one of their own traps]] while attempting to poach the dinosaurs.]]
94** In ''Fallen Kingdom'', she has several, since her predatory instincts not only [[spoiler:save Owen from a pissed-off ''Carnotaurus'']], but afterward she knocks the Gyrosphere Claire and Franklin are hiding in, sending it rolling down the hill ahead of the eruption to safety. At the end of the film, she eats [[spoiler:Mills, who is an unambiguous villain and murderer. She even gets in an unknowing dig at the ''Indominus'', smashing the only recovered piece of its skeleton and therefore limiting what research Wu can carry out in the future]].
95* ActionGirl: She's a female rex, and with every appearance she makes, she proves herself to be a worthy adversary in combat against other territorial carnivores. [[spoiler:The Big One, a ''Carnotaurus'', the ''Indominus rex'', and a ''Giganotosaurus'' all fall to her, even if the latter two make her work for it.]]
96* AdaptationalHeroism: In the novel, she could come off almost as sadistic as the ''[[Film/JurassicParkIII Spinosaurus]]'' or the ''[[Film/JurassicWorld Indominus]]'', though still more realistic. By contrast, in the films, she clearly operates on territorial and predatory instincts, culminating in her VillainousRescue moment at the end of the first film. [[spoiler:In ''Film/JurassicWorld'', she's upgraded to full AntiHero status when Claire releases her to help fight the ''Indominus rex''.]]
97* AdaptationalJerkass: While still a huge threat who kills several other dinosaurs and is indirectly responsible for the death of [[spoiler:Hammond]] in the novel, she doesn't actually straight-up kill anyone, as opposed to the film where she rips Donald Gennaro in half. [[JustDesserts Then again]], [[AssholeVictim Gennaro had it coming]]. And in the end, Rexy actually ignores the humans in favor of bigger and more interesting prey: two ''Velociraptors''. Her only confirmed human kills afterwards can be counted in one hand: none other than [[spoiler:Eli Mills and Mitch, who more than had those deaths coming]].
98* AdaptationalVillainy: Rexy is depicted in a more antagonistic light in video games, most notably Telltale's ''VideoGame/JurassicParkTheGame'', where she constantly hounds Dr. Gerry Harding and his daughter Jess, not to mention she's more persistent than her appearance in the movies. Older ''Jurassic Park'' games like the arcade game licensed by Creator/{{Sega}} as well as ''Rampage Edition'' also follow this direction, making Rexy an unstoppable predator hellbent on eating the player.
99* AdvancingBossOfDoom: She's this in Grant's final level in ''Rampage Edition'' whereupon surfacing, there is no turning back, and players are forced to use any weapons they have to keep Rexy at bay as she relentlessly chases after Grant's raft. Failure to stop her would result in Rexy chomping down and devouring Grant, costing the player a life. She plays a similar role in the T.rex Carnage mission in ''Jurassic Park 2: The Chaos Continues''- here the player has to keep her from getting to close to their jeep.
100* AdvertisedExtra:
101** She appears in Platform/PlayStation version of ''VideoGame/TheLostWorldJurassicPark'', but only in the special edition ''and'' in the first level, which takes place in Isla Nublar, [[ATasteOfPower with the intent to allow players to demonstrate the awesomeness of playing as a]] ''[[ATasteOfPower Tyrannosaurus]]''. After that, you're playing as a ''Compsognathus'' and Rexy is never seen again, with the main playable tyrannosaur being the Buck.
102** Despite heavy advertisement showing her in ''Camp Cretaceous'', her only appearance in Season 1 is in a video game during the pilot. Justified, given that she would be locked in her enclosure for most of the season.
103* AnimalsNotToScale: Downplayed. She's portrayed as noticeably larger than the largest known ''Tyrannosaurus'' specimens in real life, particularly in the later films. The largest real-life ''T. rex'' is estimated to be about four meters tall and just under thirteen meters long, but Rexy is portrayed well over five meters tall and closer to fourteen meters long. Notably, while she's (fairly) consistently portrayed as being unusually huge ''in canon'', being the only tyrannosaur to outsize the ''Spinosaurus''[[note]]Interestingly, it's recently been proposed that the maximum size range of ''Tyrannosaurus'' was likely up to 50% larger than the biggest known specimens, meaning it would be entirely possible (if exceptionally rare) for an individual ''Tyrannosaurus'' in real life to rival or even ''surpass'' Rexy in size[[/note]].
104** Interestingly, while she's definitely very long for a T. rex, her canon weight of 7 tons is actually quite a bit lighter than a T. rex of her prodigious size would be. She should weigh in the ball park of 11 tons ''at least''. This is a case of ScienceMarchesOn as scientists have found that T. rex was considerably more bulky than they were thought to be in the 90s.
105* AntiHero: While a ferocious predator, she does indirectly play the role of a hero who ends up saving human lives, if mainly because there's a much more dire threat that even she sees as more trouble than competition and generally doesn't care much for human lives unless they either piss her off too much, or they leave her territory. Due to her being the most recurring dinosaur, Rexy is also the main anti-heroine of the franchise
106* AntiVillain: In times where she's the biggest and most active threat to the protagonists, Rexy doesn't recurringly antagonize them and instead prefers to scare them away from her domain. At the end of the day, she's a natural apex predator who hunts for sustenance and is a wild animal with her own needs.
107* AwesomeMomentOfCrowning: In a way, she gets one for each film she's in:
108** In one of the most iconic scenes of ''Jurassic Park'', Rexy--[[spoiler:after throwing the Big One into the ''T. rex'' skeleton]]--turns around and roars in triumph while the "When Dinosaurs Ruled The Earth'' banner falls down as if it's a crown bestowed upon her.
109** At the end of ''Jurassic World'', where [[spoiler:she stands atop the highest heliport and roars victoriously, reclaiming her kingdom]].
110* BadGuysDoTheDirtyWork: Rexy's responsible for killing the Big One and the [[spoiler:''Indominus rex'']], both battles resulting in some unpleasant injuries. On the human side, she ate both [[spoiler:unrepentant murderer Mills and a would-be big game hunter Mitch.]] However, she's not much of a baddie since her only motivation for attacking humans is hunger or them being in her territory.
111* BadVibrations: Her footsteps cause these, heralding her memorable BigEntrance in the first movie.
112* BadassInDistress: Rexy is basically this due to her old age in the ''Jurassic World'' trilogy.
113** In the climax of ''Jurassic World'', Rexy is slowly getting her ass kicked by the ''Indominus rex'', who would have killed her if Blue had not arrived just in time to distract the hybrid.
114** Rexy spends the bulk of ''Fallen Kingdom'' out of action, she is one of the dinosaurs that Claire and Owen have to rescue from an erupting Nublar [[spoiler:before she is captured by Wheatley and subsequently imprisoned in Lockwood Manor, escaping only at the very end]].
115** [[spoiler:In the climax of ''Dominion'', Rexy is briefly knocked unconscious by the ''Giganotosaurus'', and she would have been killed if Kayla had not lured the ''Therizinosaurus'' to distract the larger theropod.]]
116* BashBrothers: ''Bash Sisters'' in this case, but Rexy does cooperate with Blue during their battle against the ''Indominus rex'' once the latter saves the former from being killed. Not only do the duo win, but they even leave on amicable terms, despite Rexy's bad experience with raptors in the past.
117* BehemothBattle: Specifically, Rexy has one against a ''Triceratops'' in the Telltale game, the ''Indominus rex'' in ''Jurassic World'', a ''Giganotosaurus'' in ''Dominion'', and a ''Tarbosaurus'' in ''Jurassic World Camp Cretaceous: Hidden Adventure''. They're about as grand and intense as they're marketed to be.
118* BehindTheBlack: In ''Film/JurassicPark1993'', she shows up without sound or anyone even seeing her 'till she snags a raptor out of midair during the climax. Both the raptors and the humans only notice her the moment the viewer does.
119* BigDamnHeroes: This is her main entrance in case she's playing the role of an AntiHero.
120** While not really paying them attention, Rexy saves the remaining survivors by suddenly ambushing one of the raptors and chomping down on her. With The Big One having diverted her attention to avenge her partner, this allowed the survivors enough time to exit the Visitor Center and leave the island.
121** {{Inverted|Trope}} in the fourth film where it's Rexy who has to be saved by someone else playing this trope straight, in this case, Blue, who charges at the ''Indominus'' before she could land a killing blow, allowing Rexy to recover and fight back.
122** In ''Fallen Kingdom'', Rexy ambushes a ''Carnotaurus'' who was attacking a gyrosphere with Claire and Franklin being trapped in it, inadvertently saving their lives alongside Owen's.
123* BigBad:
124** {{Subverted|Trope}} in the first film. Despite being ''the'' star dinosaur, even InUniverse by [=InGen=] as well as presenting the first sense of horror and danger, Rexy is ultimately overshadowed by The Big One and her ''Velociraptor'' pack, who end up being more recurring and actively malicious threats. If anything, Rexy ends up becoming the franchise's primary AntiHero.
125** Played straight in the [[VideoGame/JurassicParkArcade arcade version of the first film]], where Rexy is the main dinosaur threat, chasing you throughout Isla Nublar, and being fought thrice in the first, second, and last levels alongside a second tyrannosaur in the latter. Even then, she remains a NonMaliciousMonster, merely chasing you because, as far as she's concerned, you're easy food and she ends the game being tranquilized and transported, likely to her exhibit.
126** Also played straight in ''Ride/JurassicParkRiverAdventure'', where Rexy is the main predator throughout the ride, and it's stated that she's stalking the visitors throughout the ride. She makes an appearance towards the end, attempting to attack the raft before it plunges down an 85-foot drop from a waterfall. In the ''Jurassic World'' retheme, Rexy is replaced by the ''Indominus rex'', with Rexy herself only making a cameo.
127* BigEntrance: In ''Jurassic Park'', Rexy has one of the most famous Big Entrances in cinematic history, [[spoiler:preceded by impact tremors and culminating in everyone present looking on in horror as she effortlessly breaks free. In ''Jurassic World'', her entrance is equally epic but tonally distinct. As a combination of ominous drums and an increasingly heroic overture play, her paddock door opens and she strides out of the darkness. The whole scene balances the sense that this animal is as dangerous as the ''Indominus'' yet is still presented in the film in a heroic light.]]
128* {{Bookends}}: Rexy manages to have these every once in a while.
129** In the first film, the crisis at Jurassic Park begins with Rexy breaking loose and attacking the guests. It ends with her breaking into the Visitors' Center and attacking the Velociraptors that threaten the surviving guests.
130** In the fourth film, Rexy is in her paddock at the beginning. The final shot of the film is her walking up to a helipad and giving out a triumphant roar, signifying her newfound independence as a free animal.
131** Franchise-wide, Rexy is a solitary animal and is never seen with anyone of her own kind, with the implication that Rexy had never encountered a fellow ''Tyrannosaurus'' in her life. [[spoiler:One of the last shots in ''Dominion'' is her encountering two ''Tyrannosaurs'' at the Biosyn Valley, namely the ''Tyrannosaur'' Buck and Doe from ''The Lost World'']].
132* BreakoutCharacter: In a sense. She was always intended to be a big part of the film but once the raptors were introduced, she originally disappeared from the rest of the film. When searching for an ending, Spielberg supposedly realized that Rexy was the true star of the flick, and had her endgame rescue added in. She went on to be the most recurring dinosaur in the franchise, appearing in numerous non-canon comics and video games, before returning to the films with the World films.
133* TheBusCameBack: There were several other ''T. rex'' specimens who appeared in ''Film/TheLostWorldJurassicPark'' and ''Film/JurassicParkIII'', but the ''T. rex'' in ''Film/JurassicWorld'' is this original ''T. rex'' who is being featured after a 22-year absence.
134* CampingACrapper: By the time Rexy demolishes the restroom stand thanks to Malcolm's botched attempt at distracting her, Gennaro is still sitting on a toilet. Quivering at the sight of the tyrannosaur, Gennaro immediately gives away his position, prompting Rexy to swiftly devour him, with the toilet getting broken down upon impact.
135* ClifftopCaterwauling: At the end of ''Film/JurassicWorld''. It's exactly as awesome as it sounds, and the triumphant music that plays during the scene makes it even more awesome.
136* CombatAndSupport: In her team-up with [[spoiler:Blue, Rexy acts as the Combat by dealing hard blows on the ''I. rex'' while Blue distracts it from fighting properly]].
137* CombinationAttack: Linking to CombatAndSupport above, Blue's distraction tactics against the ''Indominus'' allow Rexy to capitalize on her strength and weight, knocking the monstrous hybrid several times whilst not being able to pay attention to two predators attacking and distracting at the same time.
138* CompositeCharacter: There were two ''Tyrannosaurus rex'' in the book, an adult and a juvenile. While Rexy is primarily based on the adult ''T. rex'', she also fulfills the juvenile's role of eating the assigned caretaker who abandons Hammond's kids during the breakout. Interestingly, ''Film/JurassicWorld''[='=]s [[AllThereInTheManual website]] mentions that the old ''T. rex'' paddock was intended to house both an adult ''T. rex'' and a juvenile one.
139* CoolOldLady: By the time of the ''Jurassic World'' trilogy, Rexy is very old by ''Tyrannosaurus'' standards, but she is still a powerful and experienced predator [[spoiler: as the ''Indominus rex'', a ''Carnotaurus'' and a ''Giganotosaurus'' all learned the hard way.]]
140* CoveredInScars: Over her thirty years, Rexy has been in the wars once or twice. There are the injuries on the left side of her back, neck, and jaw gained from The Big One in ''Jurassic Park''. She's also got a large number of small scars around her nose and eyes likely gained from living in the wild and several big cuts along her right side and her legs, corresponding to some of her ''Indominus'' wounds.
141* CurbStompBattle: Her "fight" against The Big One can easily be summed up as this. The only reason Rexy has blood drawn on her is that The Big One attacked first in a moment of distraction when the tyrannosaur was to feast upon her raptor companion that she killed. The moment Rexy lands a good bite on The Big One, the fight is immediately over.
142* CurbStompCushion: Her fight against the ''Indominus rex'' is this. Unlike Owen's Raptor Pack, Rexy manages to score a few good rams and bites, even drawing first blood on her opponent. Unfortunately, the ''Indominus'', having literally been designed to be stronger than a ''T. rex'', manages to overwhelm and pin down her adversary shortly after. Rexy would have died had it not been for Blue's sudden interference.
143* DemotedToExtra: In ''Fallen Kingdom'' Rexy doesn't get as much screen time or focus as she does in the previous film, spending most of it in captivity by Mills' goons. Even then, she does get the killing blow on Mills, if mainly by sheer coincidence.
144* DiskOneFinalBoss: Much like her novel counterpart, Rexy is introduced to be the main dinosaur threat, having come ''very'' close to killing the heroes on two occasions. However, she takes a backseat and the ''Velociraptors'' end up becoming the primary threat to be dealt with. Unlike the novel, Rexy isn't put out of commission, but rather makes a [[BigDamnHeroes sudden anti-heroic move by killing the remaining two raptors when they got the heroes covered]].
145* DestructiveSavior: Rexy and Blue are the ones to defeat the ''Indominus rex'', saving the heroes and allowing the survivors to return to their homes peacefully and the dinosaurs to once again claim Isla Nublar for themselves for the next three years, albeit at the cost of Rexy destroying several buildings in Jurassic World, though by that point, the park was forced to become completely defunct.
146* DisneyDeath: [[spoiler:She appears to have died in the climax of ''Dominion'', getting trounced by the ''Giganotosaurus''. But when the ''Therizinosaurus'' draws the Giga's attention, Rexy's motionless body suddenly moves and attacks the Giga while it is distracted.]]
147* TheDogBitesBack: [[spoiler:After being bullied out of her meals by the ''Gigantosaurus'' in Biosyn's Sanctuary, Rexy gets her revenge by driving the Giga into the piercing claws of the ''Therizinosaurus''.]]
148* TheDreaded: She inspires a nervous silence in the control room even before she breaks out. Once she does, everyone on the island soon decides to nope the hell out of there the minute she shows them she ''really'' means business. This saves their lives. [[spoiler:The Big One, who, for some reason, decides ''not to run away from the very large and very dangerous dinosaur'', dies at her hands -- well, teeth, anyway.]] [[spoiler:Later, during the events of ''Camp Cretaceous'', she's very much at the top of the food chain on post-abandonment Isla Nublar, and so much so that a mixed species herd of dinosaurs (including giant ''Brachiosaurus'') which had been stampeding in one direction promptly turn around the other way the moment they see her.]]
149* EarnYourHappyEnding: [[spoiler:Rexy has lived in solitude for more than 30 years, surviving against the odds multiple times. After finally defeating her most primordial rival, her story ends with her encountering members of her own species for perhaps the first time in her life, with the implication being that she will spend her final years as part of a family.]]
150* EnemyRisingBehind: [[spoiler:Rexy gets a great one of these after recovering from the ''Giganotosaurus''[='s=] assault, slowly rising into view behind the larger theropod as it's distracted by the ''Therizinosaurus''.]]
151* ExitPursuedByABear: Seemingly a favorite of Rexy, being the eventual dispatcher of the main villains in ''Jurassic Park'' and ''Fallen Kingdom''. Subverted in ''Jurassic World'', where Claire attempts to [[SummonBiggerFish invoke this]] against the ''Indominus rex'', but it's ultimately the ''Mosasaurus'' that gets the honor of finishing it off.
152* FearsomeFoot: Its first appearance puts a particular emphasis on her foot, particularly when she has Grant and Lex cornered and is curious about them. Its currently the Trope Image.
153* FinalBoss: In licensed games based on the first film, Rexy is often the last opponent Dr. Grant has to deal with. Notably, there's no way to actually kill her, all Grant can do is stay far away from her until the end of the level.
154* FirstBlood: [[spoiler:In the fight against the ''Indominus'']], Rexy draws first blood.
155* FoeTossingCharge: After getting a second wind in her fight against the ''I. rex'', [[spoiler:Rexy hurls it against the fence around [[AlwaysABiggerFish the Mosasaurus' lagoon]]]]. [[spoiler:She pulls this out again after recovering during her fight with the ''Giganotosaurus'', taking the opportunity to tackle it when it's distracted by the ''Therizinosaurus'' and throws it onto the other dinosaur's claws.]]
156* ForceAndFinesse: In the battle against the ''Indominus'', Rexy serves as the force to Blue's finesse, utilizing her great strength and weight to deliver damage and knockback while Blue is lithe, but acrobatic and intelligent, using her wits and agility for distraction.
157* GenerationXerox: Just like her Cretaceous ancestor, Rexy has a rivalry with a ''Giganotosaurus''. [[spoiler:However, her ancestor was killed by her rival, while Rexy survives and is able to kill hers.]]
158* GeneticMemory: The Extended Edition of ''Dominion'' implies that Rexy remembers how her Cretaceous ancestor [[spoiler:fell to a ''Giganotosaurus'' millions of years ago, and that memory is enough to give her HeroicSecondWind against her modern adversary]].
159* GiantEqualsInvincible: Rexy is this in the older ''Jurassic Park'' licensed games where all the player can do is shoot and bombard the tyrant lizard in an effort to daze or slow her down. No matter how much is thrown at her, Rexy isn't going to die.
160* GoFetch: On the receiving end of this, twice in a row. [[DrawAggro Grant draws a flare and throws it away from the jeep Rexy was attacking]], saving Lex and Murphy. Malcolm tries the same thing, and it fails horribly, resulting in Malcolm getting injured and Gennaro getting eaten.
161* GodzillaThreshold: She's the "Godzilla" in this case as while Owen, Claire, and Lowery are desperate in bringing down the ''Indominus'' after she kills most of the raptors, Gray suggests "more teeth", giving Claire the idea to release Rexy in an effort to better their chances of fighting the ''Indominus'' back. It pays off with Rexy and a surviving Blue contributing to the ''Indominus'''s death, saving Isla Nublar, the dinosaurs, and survivors of Jurassic World.
162* GoodScarsEvilScars: Her scuffle against The Big One in the first film, while one-sided on Rexy's part, saw her endure everlasting scars from where the raptor attacked her. Nevertheless, the scars show off her age and reputation as a battle-hardened dinosaur, predator, and an AntiHero. She gains more scars after her fight against the ''Indominus''.
163* HairTriggerTemper: Her Aggression Index is listed as "High". The former statement is ''not'' an understatement [[spoiler:and comes in very handy in ''Jurassic World'' in the fight against the ''Indominus rex''.]]
164* TheHeavy: She's the most recurring dinosaur and the first one to attack the protagonists, splitting them up, but she's DemotedToExtra in favor of the raptors. [[spoiler:She ironically helps save the protagonists in the end by killing the raptors attacking them.]]
165* HellIsThatNoise: She has two of note in the first film; one includes the loud, thunderous footsteps she makes to announce her arrival, which all characters treat with quiet dread when they hear it. The other is her roar, which is shown to be deafening up close and likely to strike terror in any human who hears it.
166* HeroicSecondWind:
167** [[spoiler:She takes a severe beating in the opening blows of the fight with the ''Indominus rex'' (getting body slammed, savagely mauled on her flanks, and thrown headfirst into a souvenir booth). Blue's intervention not only saves her life but when Rexy re-enters the fight, she's slamming the ''Indominus'' through buildings and throwing it like a ragdoll.]]
168** [[spoiler:Similarly, after getting knocked unconscious by the ''Giganotosaurus'', the intervention of the ''Therizinosaurus'' keeps her from being finished off and she comes back into the fight and quickly takes advantage of the situation.]]
169* HistoricalBadassUpgrade: ZigZagged. Rexy has [[LivingMotionDetector vision problems]] in the first film unlike the real deal and scientific studies since the film's release suggested the real-life ''T. rex'' was just as tough if not tougher than Rexy when it comes to combat. However, Rexy has two key advantages over her real-life counterpart: 1) As Zia Rodriguez points out, she can live significantly beyond the lifespan of a real ''T. rex'' thanks to modern healthcare provided by her caretakers. And 2) She can run up to 32 MPH while the real animal is generally believed to have been only capable of about 12 MPH.
170* HowTheMightyHaveFallen: [[PlayingWithATrope Played With]]; Rexy was the dominant carnivore on Isla Nublar for almost 3 decades. At the Biosyn facility in the Dolomites, she's suddenly in direct competition not with a psychotic killer but another apex predator; one that's bigger, younger, and fitter than she is. When she attempts to defend a deer carcass from the Giganotosaurus, she's quickly driven off. [[spoiler:But as she demonstrates in the finale, she's not willing to fully give up the crown without a fight and demonstrates she's capable of taking it back using her experience as much as anything else.]]
171* TheJuggernaut: Once she gets going, she is relentless and completely unstoppable, smashing through any obstacle that gets in her way, whether it be a tree while chasing a Jeep, or a ''Spinosaurus'' skeleton while pursuing Claire.
172* JustDesserts: As a known Man-eater, she has been on the delivering end of this onto several human Villains/{{jerk|ass}}s including [[spoiler:Eli Mills, Mitch, and Gennaro.]]
173* KnowWhenToFoldEm:
174** During the jeep chase, Rexy gives up on chasing the vehicle as soon as it reaches a speed she can't match, rather than waste the energy.
175** In a Dino Tracker video, Rexy attacks an ''Apatosaurus'' herd. When the adult member she engages into battle hits her with a powerful warning tail whip, she promptly retreats afterwards, recognizing they're too dangerous to hunt.
176** After being bitten in the snout by the ''Giganotosaurus'' when fighting it over a deer carcass, Rexy figures it's too much trouble to be worth it and merely walks away before she can receive further injuries from the larger theropod.
177* LargeAndInCharge: Rexy is the largest ''Tyrannosaurus'' and the third biggest theropod in the franchise (only the ''Giganotosaurus'' and ''Indominus'' are bigger. The ''Therizinosaurus'' is slightly taller but not as heavy). She's also regarded as the uncontested top of the Isla Nublar food chain, dwarfing all other predators and capable of bringing down even the giant sauropods on the island.
178* LastOfHerKind: Born in 1988, the oldest among seven ''Tyrannosauruses'', Rexy has outlived all of her known "siblings" and is the last known surviving dinosaur from the [=1980s=] and the original park. It was thought she was the last of her species due to reports that Isla Sorna's ecosystem had been destroyed, as was believed and reported on by the Dinosaur Protection Group; but this was revealed to be untrue with Mantah Corp's captured ''Tyrannosaurus'' being from Site B. [[spoiler:She later encounters the Buck and Doe ''T. rexes'' in the abandoned Biosyn Valley.]]
179* LetsYouAndHimFight: Rexy is bought into this by Claire in a desperate plan to release and bring along a large predatory dinosaur to fight the ''Indominus rex'', who has been wrecking Isla Nublar nonstop since her escape. When the two finally confront each other thanks to Claire throwing a flare she used to guide the tyrannosaur unto the hybrid dinosaur, Rexy starts off with a bellowing roar before drawing first blood.
180* LightningBruiser: Hammond clocked her at 32 miles per hour. She's also very big... and apparently resilient to trees. [[spoiler:Throughout the ''Jurassic World'' trilogy, she is incredibly fast and vicious for a ''rex'' of her age and size.]]
181* LivingMotionDetector: Dr. Grant once touted a scientific theory that the vision of a ''T. rex'' is based on movement, and Rexy seems to prove that theory when she fails to find the motionless Grant and Lex. But since this theory has been the subject of ridicule in real life, Rexy's vision problems have been quietly dropped since her return in ''Jurassic World''.
182* MadeOfIron: [[spoiler:Even though Rexy took a rather savage beating from the ''Indominus'' at the beginning of their throwdown in the climax, once she got a [[HeroicSecondWind moment to recover]], she was unhindered and, if anything, just seemed more pissed off by her injuries than anything else. Likewise, the final scene of ''Jurassic World'' shows Rexy to be in excellent shape in spite of her age and injuries from the ''Indominus'']].
183* {{Mascot}}: The face of Jurassic World. In fact, when Dr. Wu talks about the motivation for engineering the ''I. rex'', he says that the park "needed a new ''T. rex''".
184* MascotVillain: {{Downplayed|Trope}}; Rexy does try to kill the kids and is an extremely dangerous force of nature in the first film, but that's because she's a predator who's acting out of her own natural instincts, not to mention it's the Big One and her ''Velociraptor'' pack that are the main threat to the protagonists. Further {{subverted|Trope}} when Rexy ends up becoming an AntiHero, though she does have her moments of being an AntiVillain.
185* MightyRoar: She unleashes one of the most [[SignatureRoar well-known]] (and [[StockSoundEffects most used]]) in cinema. [[spoiler:She still has it by the time of the ''Jurassic World'' trilogy.]]
186* NeverMessWithGranny: Almost three decades old by ''Jurassic World'' and the oldest known living dinosaur. An elder by ''T. rex'' standards (the longest-lived ''T. rex'' found was 28), Rexy's a bit more gaunt and scarred, she's missing a few teeth, and her walk is noticeably stiffer. In ''Fallen Kingdom'', it's even shown that her roar, while still sonorous, isn't quite what it used to be. [[spoiler:But she still puts up a better fight against the ''Indominus'' than any other opponent and plays a major role in finally defeating it. Interestingly, Zia noted that through a combination of a life half-lived in captivity and the cloning process, it's likely that Rexy will probably live beyond a natural lifespan. When she eventually encounters the ''Giganotosaurus'', she is 34 years old -- a minimum of 30 years older than the other dinosaur -- but puts up a solid fight and uses her experience to take advantage of an opening to quickly finish her opponent off]].
187* NiceJobFixingItVillain: She's not technically a villain -- she hunts only when she ''needs'' to -- but she noms the raptors in the first film. In that situation, nomming the raptors is a ''good'' thing. [[spoiler:Also, contributing to the demise of the ''Indominus rex''. This is a good thing, a ''very'' good thing.]]
188* NoHoldsBarredBeatdown: Despite getting the first hit and displaying a better fighting chance than the Raptor Pack, Rexy still ends up on the receiving end of the trope from the ''Indominus'', who proceeds to thrash the tyrant lizard around with a little effort and maul her to death's door, only being saved by a timely intervention from a still-living Blue.
189* NominalHero: While not exactly on the heroes' side, Rexy does see any antagonistic dinosaur as a threat and villainous humans as potential prey. Her killing The Big One, Mitch, and Mills is basically her putting a stop to a major threat. Of course, there's also her battle against the ''Indominus'' and the ''Giganotosaurus'' which ends up saving the heroes' lives.
190* NonMaliciousMonster: Although Rexy breaking out is what kicks off the start of the disaster in the first film, ultimately she's just a predatory and territorial animal rather than a true villain. [[spoiler:In fact, near the end, she saves Alan and the rest when she attacks and kills the ''Velociraptors'' that were about to attack them]]. Even in ''Fallen Kingdom'', when she and Owen wind up trapped in a container, her reactions are her understandably freaking out rather than trying to eat him.
191* OlderHeroVsYoungerVillain: [[DownplayedTrope Rexy is an anti-hero at most]], but given she's 30 years old by that point and a relic from the Jurassic Park days, she qualifies in comparison with any adversaries she faces off in the ''Jurassic World Trilogy''. In ''Jurassic World'', she competes against the ''Indominus rex'' who was recently created for the titular park to renew the titular park's popularity with hybrid dinosaurs, and in ''Dominion'', Rexy challenges a ''Giganotosaurus'' created by Biosyn a couple of years ago by estimate.
192* OneHitKill: Being a ''Tyrannosaurus'' having the most powerful bite out of any land animal means a single chomp makes nearly anyone a goner if they're caught. In video games, Rexy's bites will enforce that you will die instantly and start a level all over again.
193* QuizzicalTilt: She does this occasionally in the first film, mainly due to her curiosity in not having known about humans all that much. She does this to Lex and Tim's jeep to assess whether she could attack it and again to Gennaro upon exposing him by destroying the restroom, expressing curiosity upon him before lunging for the kill.
194* RecurringBoss: In the licensed arcade game of the first film, Rexy is fought three times, specifically in Levels 1, 2, and 4. For bonus points, she's the first ''and'' last dinosaur you fight against.
195* RetiredBadass: By ''Film/JurassicWorld'', Rexy is already past her prime and seems content with a semi-domesticated life. On a meta-level, Colin Trevorrow compares her appearance in the film and [[spoiler:her battle against the ''Indominus'' as her personal ''Film/{{Unforgiven}}'']].
196* RightfulQueenReturns: In ''Film/JurassicWorld'', when she's called upon to help save the day.
197* RoarBeforeBeating: She roars occasionally before attacking her enemies and prey. She announces her presence in this way before the two jeep attacks in the first film and when confronting the ''Indominus'' for the first time during the 2015 Isla Nublar Disaster.
198* ScarsAreForever: The main clue that she is the same ''T. rex'' as always is the presence of scars corresponding to the raptor fight in the climax of the first film. [[spoiler:She picks up a bucketload more following her fight with the ''Indominus'', but Rexy gave as good as she got.]]
199* SheIsTheKing: "Rex" translates to "king", meaning ''Tyrannosaurus rex'' translates to "Tyrant Lizard King." Rexy is female.
200* ShownTheirWork: In ''Dominion'', she is redesigned with non-pronated hands just like real theropods.
201* SignatureRoar: Her roar is impossible to mistake for anything else and [[StockSoundEffects has frequently been recycled]]. Ardent fans of the film series will be able to recognize the sounds of the other dinosaurs just as well; some of the notable ones are ''[[GentleGiant Brachiosaurus]]'' and ''[[RaptorAttack Velociraptor]]''. Interestingly, the iconic high-pitched, almost pinched sound in Rexy's roar was provided by a baby elephant's first attempts at trumpeting. The rest of it was built out of a lion, a tiger, and an alligator.
202* SparedByTheAdaptation: [[spoiler:In the original novel, Rexy is taken out shortly before the novel reaches its DarkestHour, succumbing to the tranquilizers that Muldoon fired upon her two hours ago. She is never seen or mentioned again after she passed out and, according to Wu and later the population count, most likely drowned in the pool she was in. [[MakeSureHesDead The Costa Rica napalm bombings made double assurance of her demise]]. In the ''Jurassic Park'' movie, none of these two events occurred, which allows Rexy to reach the Visitor Center in time to rescue the protagonists from the raptors and later allows the Masrani Global Corporation to move her to a new exhibit enclosure in ''Jurassic World'' where 22 years later, she would be released to fight the ''Indominus rex''.]]
203* StealthyColossus: The ''T. rex'', whose presence throughout the first film has been indicated by earth-shattering footsteps, manages to get into the Visitor Center without anyone noticing, before attacking the raptors. In ''Fallen Kingdom'', she is shown to ambush her prey without warning, best demonstrated with [[spoiler:[[BigBad Mills]] at the climax of the film]].
204* StrongAndSkilled: The ''Indominus'' was a powerhouse with no real fighting experience that relied on its size and adaptability to win fights. Rexy is incredibly strong and has also lived in the wild for a decade before Jurassic World opened. She's much more experienced in a fight and shows it, being capable of completely changing her fighting tactics once she's recovered from her first round with the hybrid. [[spoiler:Shows this again when fighting the ''Giganotosaurus'' as rather than charging in once she's recovered from the initial takedown, she waits for the other theropod to be distracted and goes for a single hit kill]].
205* SuperPersistentPredator:
206** {{Subverted|Trope}}; Rexy does chase after anything she can sink her jaws onto, but she does show some restraint and will back away if the effort is not worth it. For example, she chases a rescue jeep sent out to rescue Grant, Malcolm, Lex, and Tim, but eventually stops after the jeep leaves her territory. In ''Dominion'' after getting her snout mauled by the residential ''Giganotosaurus'' over a deer carcass, Rexy leaves, figuring that fighting against a rival predator over a small corpse is pointless.
207** Played straight in ''VideoGame/JurassicParkRampageEdition'', where Rexy gives chase to Dr. Grant in the final level and ''won't'' stop until the player reaches the end. All Grant could do is use whatever weapons he has to slow Rexy down before she could catch and devour him.
208* SuperStrength: Even for a dinosaur her size, Rexy is monstrously strong. During the fight with the ''Indominus'', she twice demonstrates this, first by grabbing the 10-tonne animal in her jaws and physically hurling it several dozen feet and then following up by tossing it a similar distance using her head. Her being able to topple the ''Indominus'' is one thing but she's essentially able to lift her own entire body weight plus change and hurl it through the air. [[spoiler:In her final battle against the ''Giganotosaurus'', Rexy uses all of her strength to push the larger theropod into the claws of the ''Therizinosaurus''.]]
209* TagTeam: With Blue against the ''Indominus'' at the climax of ''Jurassic World''. They prove to be more formidable than the hybrid monster, bringing it close to defeat before the ''Mosasaurus'' claims the kill.
210* ATasteOfPower: A variant of sorts; the first level in the special edition of the [=PS1=] ''[[VideoGame/TheLostWorldJurassicPark Lost World]]'' game takes place during the 1993 Isla Nublar Downfall and with Rexy as the playable character to deliver the promise of players being able to play as a ''T. rex''. Upon completing the level, the play immediately switches to controlling a ''Compsognathus'' and while ''Tyrannosaurus'' would eventually become playable again, it is a different one, namely the Buck from Isla Sorna.
211* TerrifyingTyrannosaur: She invokes nervousness from the Jurassic Park staff and her literal breakout debut on the silver screen redefines what it means to be scared by a ''T. rex''. Rexy is also the most powerful ''T. rex'' of the franchise and even in her old age during the ''Jurassic World'' era, she can put up a fight against larger therapods and still hunt humans for a quick snack.
212* TheToothHurts: When she attacked Lex and Timmy's explorer, she struck the roof with such force that she snapped one of her front teeth off. This gives her a prominent diastema which serves as one of her distinguishing traits.
213* ThemeMusicPowerUp: A variant; the music during the ''Velociraptor'' chase in the Visitor Center is intense and scary, especially when the raptors have the heroes cornered... until Rexy suddenly kills one of the raptors, immediately followed by the ''Jurassic Park'' Theme playing, signaling some sort of hope and chance being given to the human survivors.
214* UnstoppableRage: [[spoiler:She's already furious when she sees the ''I. rex'' intruding on her territory. But after receiving a savage beating and Blue giving her a HeroicSecondWind, she goes full-on berserk and gives the ''I. rex'' an ''even more intense'' beatdown.]]
215* UseYourHead: She is willing to use her skull as a battering ram if need be. She does this to a ''Spinosaurus'' skeleton before encountering the ''Indominus'', and she uses it offensively against her as well as the ''Giganotosaurus'' in ''Dominion'' when they finally start throwing down. In ''Fallen Kingdom'', she headbuts an unsuspecting ''Carnotaurus'', inadvertently saving Owen, Claire, and Franklin.
216* VictoriousRoar: After defeating the ''Big One'', the [[spoiler:''Indominus'']], the ''Carnotaurus'', the [[spoiler:''Giganotosaurus'']] and the [[spoiler:''Tarbosaurus'']] across all of her film appearances thus far, she always lets off one of her [[SignatureRoar famous roars.]]
217* VillainKiller: [[spoiler:Rexy eats the DirtyCoward lawyer Donald Gennaro and the CorruptCorporateExecutive Eli Mills.]]
218* VocalEvolution: Her roars in ''Fallen Kingdom'' and ''Dominion'' sound deeper, more guttural, and more bellow-like to emphasize her old age.
219* TheWorfEffect:
220** Briefly, in ''World''; [[spoiler:the ''I. rex'' puts down a massive beating on the old girl when they initially face off. Justified since the ''I. rex'' was tailor-made with all of her strengths and ''more'', as well as because Rexy was initially fighting as she would in a territorial fight, whereas the ''I. rex'' was fighting to kill from the start; it takes an assist from Raptor Blue to give her a second wind]].
221** She's on the giving end in ''Fallen Kingdom''. As the ''Carnotaurus'' is menacing our heroes, Rexy comes out of nowhere, grabs it by the neck, and pins it to the ground. The real icing on the cake is that she doesn't deliver the final blow with her infamous jaws, she kills the ''Carnotaurus'' by simply lifting one foot to walk away, leaving all of her considerable tonnage on the poor animal's neck.
222** [[spoiler:When she first encounters the ''Giganotosaurus'', after a brief struggle she retreats rather than fight, highlighting the power of the new dinosaur while also setting up the later battle for the apex position]].
223* WorthyOpponent: She appears to regard Blue as this, as she shares a look with her after [[spoiler:they've defeated ''Indominus'']] and they peacefully go their separate ways.
224* WouldHurtAChild: Tim and Lex were the very first individuals that Rexy attacks on-screen. Interestingly, while a horrifying scene, it doesn't really villainize Rexy too much, so much as it displays how ferocious she is as a predator. She's acting more out of curiosity than any malice, but Grant and Malcolm thankfully put a stop to that... with a whole slew of new problems. On another note, Rexy does antagonize a baby ''Triceratops'' in the Telltale game as well as threatening the Campers in ''Camp Cretaceous''.

231
232->''"All I want in return for my services is the right to hunt one of the ''Tyrannosauruses''. A male, a buck only."''
233-->--'''Roland Tembo'''
234
235A [[ExactlyWhatItSaysOnTheTin family of]] ''[[ExactlyWhatItSaysOnTheTin T. rexes]]'', consisting of a father, a mother, and a baby.
236----
237* AntiVillain: While they do eat humans and the Buck goes on a rampage in San Diego, they are just a family trying to protect their baby.
238* AscendedExtra: Of a sort. While the ''T. rex'' in the first film was a major presence, the ''Tyrannosaurus'' family in this film is the driving force of many of its events and fills the ''Velociraptors'' roles as the primary dinosaur antagonists.
239* BadassAdorable: The baby.
240* 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''.]]
241* BattleCouple: Together, they are easily the most formidable creatures on the island.
242* BigBadEnsemble: With Peter Ludlow during the second film, however, the Buck becomes the biggest threat once it goes on a rampage in San Diego to find his baby.
243* TheBusCameBack: [[spoiler:After 25 years, Colin Trevorrow confirmed on Twitter that the Buck and Doe are the two ''T. rexes'' that welcome Rexy into their family in the abandoned [=BioSyn=] Valley.]]
244* TheComicallySerious: The adults are more serious antagonists than Rexy. This makes it all the more shocking when the Buck has silly moments like drinking out of a pool.
245* ContrastingSequelAntagonist: Most obviously by being a family and having a distinct reason to continue pursuing the characters, both of which contrast Rexy in the first film. They also contrast to the Big One and its pack while they are a pack of raptors born on Isla Nublar for the original park, the Rexes are obviously a family of ''T. rexes'', while the Big One and her raptor pack were killed, the ''T. rex'' family live by the end of the second film.
246* CubCuesProtectiveParent: See the baby? Don't touch it unless you ''want'' to become ''T. rex'' chow.
247* 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. Gee, do you think [[TooDumbToLive people messing around with their baby]] had something to with that?
248* TheDreaded: Two angry ''T. rexes'' who are also parents are the kind to seriously watch out for, especially due to their tracking skills and if someone tries to steal their baby.
249* DualBoss: In the [=PS1=] game, Sarah Harding has to fight against the Buck in the final level upon ending up in a cargo hold, who is then joined along by the Doe once the former receives enough damage.
250* EscapedAnimalRampage: In the final climax, the male gets loose from its holding cell on the cargo ship and, hopped up on stimulants, goes on a destructive rampage through San Diego.
251* 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 realizes what ''he'' [[PapaWolf would do if someone tried to hurt his daughter.]]
252* TheFamilyThatSlaysTogether: To the point where we see the father teaching his son how to hunt.
253* FinalBoss: The duo tends to be the final enemies to fend off against in any licensed video games of ''The Lost World''.
254** The Buck ''Tyrannosaurus'' is the last opponent the player fights against in the Arcade version of the game.
255** In the [=PS1=] game, the player as Sarah Harding has to fight against the Buck in the cargo. Once enough damage has been dealt, the Doe joins the battle.
256* GoodParents: Part of Sarah's dispute with Burke is their opinions on ''Tyrannosaurus'' nurturing habits. Burke's is that a ''T. rex'' would abandon its young at the earliest opportunity. Sarah's is that they were very involved in the development of their offspring. Over the course of this film, Sarah is proven right, as not only are both parents ''[[MamaBear pis]][[PapaWolf sed]]'' when their baby is taken but the father is even shown teaching the infant how to make a kill. [[spoiler:Said kill being Ludlow]].
257* HandicappedBadass: The baby after he's injured.
258* HeroKiller: The parents rip poor [[spoiler:Eddie]] in half and eat him.
259* KilledOffscreen: Since Rexy is confirmed as being the last ''Tyrannosaurus'' left by the time of ''Film/JurassicWorldFallenKingdom'', it was assumed these three are dead. [[spoiler:''Film/JurassicWorldDominion'' reveals that this is not true for the Buck and the Doe, as both appear in the [=BioSyn=] sanctuary. What happened to Junior, however, is still a mystery.]]
260* LightningBruiser: They are huge, strong, and very fast. The Buck can plow through a wall without even slowing down while keeping pace with a speeding car.
261* MamaBear[=/=]PapaWolf: The parents. If you mess with their baby, they will track you across the island to eliminate you as a threat. The moment the father, already amped up thanks to the stimulant cocktail it was given on the ship, sees Ian and Sarah have the offspring in their car, it instantly stops rampaging in San Diego and gives chase, roaring in rage.
262* NonMaliciousMonster: The parents just want to save their baby. All three of them want food.
263* TheNoseKnows: The father sniffs out some of the humans at some points. He's also shown catching a whiff of his nearby infant when Ian and Sarah attempt to lure him away amidst his San Diego rampage. This ends up being one of the reasons the Buck and the Doe continue to follow the humans around the island, due to Sarah idiotically still wearing a jacket stained with the blood of their injured infant.
264* NoSell: When attacking the hunters, they are shot at with automatic weapons. The guns aren't powerful to do any damage, the rexes don't even react to them.
265* OffscreenMomentOfAwesome: The Buck has one during his transportation to San Diego on the S.S. Venture when he manages to escape his containment and kill all the crew of the ship.
266* SequelEscalation: The first film had one ''T. rex'', which was enough trouble for the humans, but now there are ''two'' of them (plus a baby).
267* SequentialBoss: In the final level of the arcade game, ''Something has Survived'', the player battles against the Tyrannosaur Doe upon them retrieving their infant and destroying the trailer. Upon defeating the Doe, she calls her mate, [[RoaringRampageOfRevenge who reacts accordingly]] and becomes the game's FinalBoss.
268* SexShifter: 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.
269* SoProudOfYou: The father certainly appears to feel this way as [[spoiler:his son kills Ludlow]]. He even seems to be ''smiling''.
270* {{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 [[spoiler:Eddie]] very tasty and want more...
271** 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. Even when they attack the combined parties, it's still not exactly hunting behavior given that they could have simply started snacking on the mass of sleeping humans all around them and the Doe is simply chasing them out of what she considers their territory, only eating Burke when he literally runs right into her jaws.
272* SuperToughness: Displayed more so than Rexy in the first film, the adults are '''tough'''. The Buck, while wreaking havoc in San Diego, rams his head into a bus and smashes it without getting a scratch on him.
273* TerrifyingTyrannosaur: What's worse than a ''Tyrannosaurus rex''? A ''T. rex'' couple that will lay vengeance upon every human they see for getting close to their baby. Their terrifying reputation is also why [[GreatWhiteHunter Roland Tembo]] agreed to help [=InGen=] capture the dinosaurs of Isla Sorna. He wants to hunt what he deems to be the greatest predator that has ever walked the earth, the ''Tyrannosaurus rex''. Specifically, the Buck.
274* TrampledUnderfoot: The Doe squishes Carter underneath her foot in a puddle, whose body does not come off until after her third step.
275* UnstoppableRage: When they think their baby is in danger and kidnapped, barely anything can slow them down. The Buck plows through a large portion of San Diego in doing so.
276* WorthyOpponent: Roland Tembo sees the Buck ''rex'' like this.
277-->'''Roland:''' Somewhere on this island is the greatest predator who ever lived. The second greatest predator must take him down.
278* 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. Junior, who would now be a fully mature adult, his fate however is still uncertain]].

287A young adult male ''Tyrannosaurus rex'' that Grant and company run into while escaping the plane crash. It proceeds to chase them, only to run into the ''Spinosaurus'' and get into a fight with the larger predator. It puts up a good fight but ends up killed.
288----
289* AdaptationalBadass: In the arcade version of the third film, the Bull manages to knock the ''Spinosaurus'' off a cliff. While it doesn't kill its rival, the Bull did at least score some kind of win.
290* AscendedExtra: It only has a brief appearance before getting offed unceremoniously. In the arcade version of ''Jurassic Park III'', it manages to actually beat the ''Spinosaurus'' by throwing it off a cliff and remains to fight the player as the boss of Stage 4.
291* BehemothBattle: Has one against the ''Spinosaurus'', though in spite of putting up a good fight, it's defeated and killed.
292* CurbStompCushion: Despite only lasting about a half-minute against the ''Spinosaurus'', it still manages to get the first takedown and multiple hits in to make the ''Spinosaurus'' work for its win.
293* DemotedToExtra: After the ''T. rex'' being the star of the franchise for two films, this one exists essentially to be killed and replaced by the ''Spinosaurus'', to show how deadly the new dino is.
294* NeckSnap: How the ''Spinosaurus'' kills it.
295* RoarBeforeBeating: The tyrannosaur roars immediately upon seeing the ''Spinosaurus'', showing that he does not like to see a fellow predator intruding on his hunting grounds.
296* SpinosaurusVersusTRex: Despite its minimal role in the third film, it does end up being the TropeMaker alongside the titular ''Spinosaurus''.
297* 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 wanting to steal its meal, but even then it should've stopped chasing them long before it actually did.
298* TerrifyingTyrannosaur: Subverted ''hard''. Normally, a ''T. rex'' in a ''Jurassic Park'' film would be the top predator of the island feared by all. But to highlight how badass the ''[[SavageSpinosaurs Spinosaurus]]'' is to the audience, [[TheWorfEffect it gets dethroned very violently and quickly]] by its new superpredator rival.
299* UnskilledButStrong: Being 37 feet long, this ''Tyrannosaurus'' was a subadult and while it does have a sizable corpse, it's shown to be that of a hadrosaur. As shown in its fight against the ''Spinosaurus'', the ''T. rex'' is powerful, but it lacks any skill and experience to combat something that is around the same size as itself, let alone a ''predator'' that's ''bigger'' in comparison. As a result, the Bull ''T. rex'' is killed, despite putting up a good effort.
300* TheWorfEffect: An infamous example, the ''Tyrannosaurus'' is the face of the franchise and the filmmakers wanted a dinosaur that could replace it. So, the ''Tyrannosaurus'' of this film encounters and fights the ''Spinosaurus'' and despite landing several blows that would have killed or crippled it in a potential real-life scenario, the ''Spinosaurus'' wins the struggle and kills its opponent.
301* WriterOnBoard: Its treatment in the third film is largely a result of scientific advisor Jack Horner's influence. Horner believed that ''T. rex'' didn't "deserve" to be the face of the franchise, and suggested that it be "replaced" with a more suitable dinosaur. Consequently, it is killed off in its only brief appearance. It doesn't even kill ''anything'' in the film, only being shown scavenging on an already dead dinosaur-- no doubt a reference to Horner's theory that ''T. rex'' was a scavenger.

308
309A ''Tyrannosaurus rex'' appearing in a flashback taking place in the Cretaceous Period, showing the animal as it naturally looks without any [=InGen=] modifications.
310----
311* BehemothBattle: Enters one with the ''Giganotosaurus'' after it approaches and challenges it.
312* BullyingADragon: It tried to intimidate and attack the equally huge ''Giganotosaurus'', an act that didn't wind up working out for it.
313* FeatheredFiend: The most blatant distinction between this animal and the [=InGen=] stock cloned from it is the natural creature sporting a layer of short feathers across its neck, shoulders, and dorsum.
314* GoofyFeatheredDinosaur: Blatantly averted. The feathers on it are subdued, but not at all hidden, and it's made clear that this is just as much a bonafide apex predator as the [=InGen=] stock we had seen.
315* LegacyCharacter: [[spoiler:''Strongly'' implied to be the ''T. rex'' that contributed the majority of Rexy/Roberta's DNA, and possibly also all ''Tyrannosaurus'' made by [=InGen=] including Buck and Doe.]]
316* ShownTheirWork: This ''Tyrannosaurus'' isn't entirely scaly like the [=InGen=] version, as the genus was very firmly nested within a group known to have feathers. Since the fossil record has nevertheless demonstrated that ''Tyrannosaurus'' was predominantly scaly, the film's depiction has only a sparse coat of filaments along its neck, arms, and dorsum as opposed to the ''Yutyrannus''-like full-body covering seen in some obsolete reconstructions. It also lacks pronated hands.
317* TerrifyingTyrannosaur: Unusually for the franchise, [[SubvertedTrope subverted]] (albeit in a much more subtle manner than ''Film/JurassicParkIII''). While this ''Tyrannosaurus'' is definitely a fearsome and formidable carnivore just like the real animal [[spoiler:and its "descendant" Rexy]], it's clear that in its natural environment it's just another predator which (as its battle with the ''Giganotosaurus'' shows) is far from invulnerable and has rival predators to contend with.

323!!!'''Appearances:''' ''WesternAnimation/JurassicWorldCampCretaceous''
324
325A mother and daughter duo of ''Tyrannosaurus'' that formerly lived on Isla Sorna before being stolen and relocated to Mantah Corp island.
326----
327* AndroclesLion: Possibly. [[spoiler:Big Eatie arrives to fight the ''Spinosaurus'', who is under Daniel Kon, just as it is menacing Darius. Whether this was her intentionally trying to protect him or just wanted to settle the score with the rival predator is ambiguous.]]
328** It should also be noted that Big Eatie [[spoiler:takes a moment to look at Darius (who is in a vulnerable position after he freed her from Daniel Kon's mind control) before walking away, seemingly realizing that he freed her.]]
329* ArtisticLicenseBiology: Big Eatie should probably be more naturally aggressive to her daughter by this point, as large predators tend to kick their young out once they reach adulthood to avoid competition for scarce food. Even social predators like wolves, which evidence suggests at least some ''Tyrannosauruses'' were, usually have family fission during the point of the offspring's full maturity. Realistically, Little Eatie should become more independent and would try to start her own family.
330** Potentially justified as their unusual living circumstances as the only two rexes on the island and the constant steady supply of food may have impacted Big Eatie's instinctive need to chase off Little Eatie as perceived competition. Her extreme attachment to her daughter, however, is a bit anthropomorphizing.
331** The idea a predator could serve as the "alpha" of a mixed species group[[note]]especially one made of multiple other carnivore species, herbivores, and juveniles of prey animals[[/note]], like how Darius claims Big Eatie acts to the raptor pair, Pierce, and the baby herbivores; is completely infeasible in nature.
332** There are no "Water Hole Truces" in nature. Predators not attacking prey around water sources usually only happens when both parties are extremely desperate-- in severe droughts, for example. In a lush, wet environment like Mantah Corp's island, a predator would see no need to hold back, and would attack any prey animal that came near it. In fact watering holes are prime hunting territory most of the time as prey are potentially distracted when drinking. Herd animals frequently only drink when they have sentries keeping an eye out for ambushes. At the very least the circumstances are potentially justified in this specific and isolated semi-domesticated ecological situation because the Eaties and the other carnivores are being provided with a steady supply of meat by Mantahcorp and thus have no need to hunt the herbivores.
333* ArtisticLicensePaleontology: {{Handwave}}d by the cloning process (which accelerates aging while also extending the lifespan), but fossils indicate that ''Tyrannosaurus'' had an aging period equivalent to humans (start out small and grow gradually, puberty starts at 13, and adulthood reached about 18 years) and lived only to their thirties, so nearly adult-sized ''Tyrannosauruses'' like Little Eatie should have outlived their parents.
334* BecauseYouWereNiceToMe: Big Eatie repays Darius for his past kindness by both leaving him alone when he was vulnerable and [[spoiler:saving his life]].
335* BigDamnHeroes: [[spoiler:After being heavily wounded by the ''Spinosaurus'', Big Eatie recovers just in time to rescue Darius while Little Eatie devours Hawkes and helps her mother in chasing the ''Spinosaurus'' away.]]
336* TheBusCameBack: In the official trailer for ''Chaos Theory'' the campers are seen encountering a ''Tyrannosaurus'' who looks exactly like Big Eatie, indicating that she and the other animals on Mantahcorp island will somehow be brought to the mainland.
337* ChemicallyInducedInsanity: Both are driven mad by drugs slipped to them by Kash, causing them to wildly lash out at each other.
338* CoveredInScars: Both of them have scars riddled all over their faces and bodies.
339* DisappearedDad: It's unknown what happened to Little Eatie's father considering ''[[Film/TheLostWorldJurassicPark The Lost World]]'' established that both parents care for their young, presumably he is either dead or was left behind on Sorna.
340* ExtremelyProtectiveChild: Little Eatie is both a loving and protective daughter to Big Eatie.
341* GoodParents: Big Eatie might be a ferocious and territorial predator, but her affection for her daughter Little Eatie is very obvious and notable, with Big Eater doing anything she can to protect and provide for her child, even if she's an adult.
342* HeroicSecondWind: [[spoiler:After being wounded grievously by the ''Spinosaurus'', Big Eatie recovers fast enough to re-engage the larger theropod and chase it off alongside her daughter.]]
343* TheLeader: Once the watering hole is established in the Forest Biome, Big Eatie is viewed as the alpha by the island's dinosaurs. If she's calm, they're calm, and vice versa.
344* MadeOfIron: While fossil evidence shows that ''T. rexes'' could suffer serious wounds and survive, these two take it to a ridiculous extent and suffer more harm than any other ''T. rex'' in the history of the franchise (not counting the video games).
345* MamaBear: Big Eatie is both a loving and protective mother to Little Eatie, [[spoiler:and she is more than prepared to fight off a pack of mind-controlled dinosaurs to rescue her cornered daughter]].
346** To a lesser degree she ends up becoming this towards [[spoiler: Darius in season 5, not only leaving him be when he is vulnerable but also seemingly saving him from the Spinosaurus.]]
347* MonsterIsAMommy: The kids are pretty shocked to encounter a ''Tyrannosaurus rex'' on this new island, even more so when they realise there are two, on top of that Mae reveals that they are actually parent and child.
348* 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, who he is and how many other ''Tyrannosauruses'' from Sorna are still alive.
349* MythologyGag: The original novel featured a pair of ''Tyrannosaurus'', an adult and a juvenile, as one of the threats the heroes face. Here, another pair, this time explicitly mother and daughter, also menace the heroes for some time.
350* NonMaliciousMonster: While Rexy was never malicious she was still the fearsome ruler of Nublar, there is a greater emphasis on making Big Eatie and Little Eatie sympathetic by making them a loving family. Season 5 goes out of its way to show them as (relatively) benevolent with Big Eatie responding to Darius' efforts to communicate to the point where she clearly makes a choice not to attack him. Once the watering hole is established, the pair are shown to be non-aggressive as long as they aren't hungry (and since the campers are keeping them fed that's not an issue) to the point where Big Eatie becomes the alpha of the Mantah Corp dinosaurs, with even Pierce deferring to her. While not "safe" in the way Bumpy and Pierce are (while playing they both have no problem chasing Darius and Brooklyn), they are by far the most approachable ''Tyrannosauruses'' in the franchise.
351* SuperiorSuccessor: [[spoiler:Big Eatie puts up a ''much'' better fight against the ''Spinosaurus'' than the Bull did, being able to fight it pretty evenly for an extended period and recovering from a near-fatal knockdown, going in for round two when Little Eatie arrives to help drive it off.]]
352* SuspiciouslySimilarSubstitutes: Big Eatie and Little (Big Eatie primarily) serve as the resident ''Tyrannosauruses'' on the island, taking over Rexy's role from Seasons 2 and 3.
353* 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, Little Eaties Father and at least another two to four from Ingen’s original seven unaccounted for.]]
354* 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 sometime 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.
355* 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 and Little Eaties father are from Ingen’s original seven ''Tyrannosauruses'' or if one or both are hatchlings from a later generation themselves. The former seems more unlikely for Big Eatie as she did not live a partially captive life or in an environment without direct competition as Rexy did.
356* WhatHappenedToTheMouse: They disappear about halfway through the storyline of Season 4 (Little Eatie lying badly injured in the jungle and Big Eatie having been taken to the medbay after her fight with Pierce) and aren't mentioned again since. However, both of them return in Season 5 as eventual nominal allies of the campers.
