Jurassic World website

An 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.

This page revolves exclusively around the film iteration of Rexy. To read about the novel incarnation, see the character page of Tyrannosaurus.

    open/close all folders 

  • Accidental Hero: 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.
    • In Jurassic Park, her timely attack on the two surviving raptors saves Alan, Ellie, Lex, and Tim.
    • 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.
    • A few weeks later in Camp Cretaceous, she would chase off trophy hunters Mitch and Tiffany from Main Street, where they were holding Darius and Sammy hostage, and would later eat one of the hunters when they became caught in one of their own traps while attempting to poach the dinosaurs.
    • In Fallen Kingdom, she has several, since her predatory instincts not only 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 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.
  • Action Girl: 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. 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.
  • Adaptational Heroism: In the novel, she could come off almost as sadistic as the Spinosaurus or the Indominus, though still more realistic. By contrast, in the films, she clearly operates on territorial and predatory instincts, culminating in her Villainous Rescue moment at the end of the first film. In Jurassic World, she's upgraded to full Anti-Hero status when Claire releases her to help fight the Indominus rex.
  • Adaptational Jerkass: While still a huge threat who kills several other dinosaurs and is indirectly responsible for the death of Hammond in the novel, she doesn't actually straight-up kill anyone, as opposed to the film where she rips Donald Gennaro in half. Then again, 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 Eli Mills and Mitch, who more than had those deaths coming.
  • Adaptational Villainy: Rexy is depicted in a more antagonistic light in video games, most notably Telltale's Jurassic Park: The Game, 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 Sega as well as Rampage Edition also follow this direction, making Rexy an unstoppable predator hellbent on eating the player.
  • Advancing Boss of Doom: 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.
  • Advertised Extra:
  • Animals Not to Scale: 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.
  • Anti-Hero: 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
  • Anti-Villain: 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.
  • Awesome Moment of Crowning: In a way, she gets one for each film she's in:
    • In one of the most iconic scenes of Jurassic Park, Rexy—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.
    • At the end of Jurassic World, where she stands atop the highest heliport and roars victoriously, reclaiming her kingdom.
  • Bad Guys Do the Dirty Work: Rexy's responsible for killing the Big One and the Indominus rex, both battles resulting in some unpleasant injuries. On the human side, she ate both 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.
  • Bad Vibrations: Her footsteps cause these, heralding her memorable Big Entrance in the first movie.
  • Badass in Distress: Rexy is basically this due to her old age in the Jurassic World trilogy.
    • 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.
    • 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 before she is captured by Wheatley and subsequently imprisoned in Lockwood Manor, escaping only at the very end.
    • 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.
  • Bash Brothers: 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.
  • Behemoth Battle: 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.
  • Behind the Black: In Jurassic Park, 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.
  • Big Damn Heroes: This is her main entrance in case she's playing the role of an Anti-Hero.
    • 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.
    • Inverted 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.
    • 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.
  • Big Bad:
    • Subverted in the first film. Despite being the star dinosaur, even In-Universe 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 Anti-Hero.
    • Played straight in the 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 Non-Malicious Monster, 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.
    • Also played straight in Jurassic Park River Adventure, 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.
  • Big Entrance: In Jurassic Park, Rexy has one of the most famous Big Entrances in cinematic history, 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.
  • Bookends: Rexy manages to have these every once in a while.
    • 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.
    • 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.
    • 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. 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.
  • Breakout Character: 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.
  • The Bus Came Back: There were several other T. rex specimens who appeared in The Lost World: Jurassic Park and Jurassic Park III, but the T. rex in Jurassic World is this original T. rex who is being featured after a 22-year absence.
  • Camping a Crapper: 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.
  • Cat Smile: Not very obvious, but she does appear to have this (albeit a toothy one) when seen in the front, as do the other Tyrannosaurus in the films.
  • Clifftop Caterwauling: At the end of Jurassic World. It's exactly as awesome as it sounds, and the triumphant music that plays during the scene makes it even more awesome.
  • Combat and Support: In her team-up with Blue, Rexy acts as the Combat by dealing hard blows on the I. rex while Blue distracts it from fighting properly.
  • Combination Attack: Linking to Combat and Support 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.
  • Composite Character: 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, Jurassic World's website mentions that the old T. rex paddock was intended to house both an adult T. rex and a juvenile one.
  • Cool Old Lady: By the time of the Jurassic World trilogy, Rexy is very old by Tyrannosaurus standards, but she is still a powerful and experienced predator as the Indominus rex, a Carnotaurus and a Giganotosaurus all learned the hard way.
  • Covered in Scars: 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.
  • Curb-Stomp Battle: 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.
  • Curb Stomp Cushion: 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.
  • Demoted to Extra: 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.
  • Disk-One Final Boss: 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 sudden anti-heroic move by killing the remaining two raptors when they got the heroes covered.
  • Destructive Savior: 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.
  • Disney Death: 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.
  • The Dog Bites Back: 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.
  • The Dreaded: 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. 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. 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.
  • Earn Your Happy Ending: 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.
  • Enemy Rising Behind: 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.
  • Exit, Pursued by a Bear: 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 invoke this against the Indominus rex, but it's ultimately the Mosasaurus that gets the honor of finishing it off.

  • Fearsome Foot: 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.
  • Final Boss: 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.
  • First Blood: In the fight against the Indominus, Rexy draws first blood.
  • Foe-Tossing Charge: After getting a second wind in her fight against the I. rex, Rexy hurls it against the fence around the Mosasaurus' lagoon. 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.
  • Force and Finesse: 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.
  • Generation Xerox: Just like her Cretaceous ancestor, Rexy has a rivalry with a Giganotosaurus. However, her ancestor was killed by her rival, while Rexy survives and is able to kill hers.
  • Giant Equals Invincible: 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.
  • Go Fetch: On the receiving end of this, twice in a row. 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.
  • Godzilla Threshold: 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.
  • Good Scars, Evil Scars: 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 Anti-Hero. She gains more scars after her fight against the Indominus.
  • Hair-Trigger Temper: Her Aggression Index is listed as "High". The former statement is not an understatement and comes in very handy in Jurassic World in the fight against the Indominus rex.
  • The Heavy: She's the most recurring dinosaur and the first one to attack the protagonists, splitting them up, but she's Demoted to Extra in favor of the raptors. She ironically helps save the protagonists in the end by killing the raptors attacking them.
  • Hell Is That Noise: 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.
  • Heroic Second Wind:
    • 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.
    • 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.
  • Historical Badass Upgrade: Zig-Zagged. Rexy has 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.
  • How the Mighty Have Fallen: 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. 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.
  • The Juggernaut: 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.
  • Just Desserts: As a known Man-eater, she has been on the delivering end of this onto several human Villains/Jerkasses including Eli Mills, Mitch, and Gennaro.
  • Kick the Son of a Bitch: In all of the films she's in, she is responsible for the death of a sociopathic monster that is threatening our heroes in that respective film, be it the Big One, the Indominus rex, or Mills. And in the case of Jurassic World: Camp Cretaceous, Mitch.
  • Know When to Fold 'Em:
    • 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.
    • 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.
  • Large and in Charge: 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.
  • Last of Her Kind: 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. She later encounters the Buck and Doe T. rexes in the abandoned Biosyn Valley.
  • Let's You and Him Fight: 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.
  • Lightning Bruiser: Hammond clocked her at 32 miles per hour. She's also very big... and apparently resilient to trees. Throughout the Jurassic World trilogy, she is incredibly fast and vicious for a rex of her age and size.
  • Living Motion Detector: 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.
  • Made of Iron: Even though Rexy took a rather savage beating from the Indominus at the beginning of their throwdown in the climax, once she got a 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.
  • 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".
  • Mascot Villain: Downplayed; 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 when Rexy ends up becoming an Anti-Hero, though she does have her moments of being an Anti-Villain.
  • Mighty Roar: She unleashes one of the most well-known (and most used) in cinema. She still has it by the time of the Jurassic World trilogy.
  • Never Mess with Granny: 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. 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.
  • Nice Job Fixing It, Villain: 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. Also, contributing to the demise of the Indominus rex. This is a good thing, a very good thing.
  • No-Holds-Barred Beatdown: 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.
  • Nominal Hero: 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.
  • Non-Malicious Monster: 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. 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.

  • Off-Model: In the first film, her CGI model and animatronic are noticeably different from each other, with the animatronic having larger teeth, differently shaped eyes, and a slightly different coloration. The later films use an altered version of the cgi model for Rexy.
  • Older Hero vs. Younger Villain: 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.
  • One-Hit Kill: 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.
  • Quizzical Tilt: 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.
  • Recurring Boss: 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.
  • Retired Badass: By Jurassic World, 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 her battle against the Indominus as her personal Unforgiven.
  • Rightful Queen Returns: In Jurassic World, when she's called upon to help save the day.
  • Roar Before Beating: 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.
  • Scars are Forever: 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. She picks up a bucketload more following her fight with the Indominus, but Rexy gave as good as she got.
  • She Is the King: "Rex" translates to "king", meaning Tyrannosaurus rex translates to "Tyrant Lizard King." Rexy is female.
  • Shown Their Work: In Dominion, she is redesigned with non-pronated hands just like real theropods.
  • Signature Roar: Her roar is impossible to mistake for anything else and 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 Brachiosaurus and 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.
  • Spared by the Adaptation: In the original novel, Rexy is taken out shortly before the novel reaches its Darkest Hour, 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. 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.
  • Stealthy Colossus: 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 Mills at the climax of the film.
  • Strong and Skilled: 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. 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.
  • Super-Persistent Predator:
    • Subverted; 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.
    • Played straight in Jurassic Park: Rampage Edition, 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.
  • Super Strength: 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. In her final battle against the Giganotosaurus, Rexy uses all of her strength to push the larger theropod into the claws of the Therizinosaurus.
  • Tag Team: 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.
  • A Taste of Power: A variant of sorts; the first level in the special edition of the PS1 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.
  • Terrifying Tyrannosaur: 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.
  • The Tooth Hurts: 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.
  • Theme Music Power-Up: 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.
  • Unstoppable Rage: 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 Heroic Second Wind, she goes full-on berserk and gives the I. rex an even more intense beatdown.
  • Use Your Head: 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.
  • Victorious Roar: After defeating the Big One, the Indominus, the Carnotaurus, the Giganotosaurus and the Tarbosaurus across all of her film appearances thus far, she always lets off one of her famous roars.
  • Vocal Evolution: Her roars in Fallen Kingdom and Dominion sound deeper, more guttural, and more bellow-like to emphasize her old age.
  • The Worf Effect:
    • Briefly, in World; 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.
    • 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.
    • 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.
  • Worthy Opponent: She appears to regard Blue as this, as she shares a look with her after they've defeated Indominus and they peacefully go their separate ways.
  • Would Hurt a Child: 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.
