The Kirby Family


Paul Kirby
"Ahem... I need change here, it only takes quarters, I think I've got... I've got about ten..."
Played By: William H. Macy

"Fine, go ahead and scream and when that Tricikloplots attacks you, don't come crying to me."

The owner of a paint & tile store who poses as a wealthy businessman in order to lure Grant onto Isla Sorna to help the Kirbys search for their son.
  • Bluff The Imposter: Paul is tricked by Billy into revealing that he never climbed K2, like he'd earlier claimed. From there, his lies quickly unravel.
  • Bumbling Dad: To Eric. Paul is a typical suburbanite father; he's well-meaning, but clumsy, lacking in useful experience or knowledge and is pretty far from an action hero. Still, he causes less damage than Amanda.
  • Chekhov's Hobby: He casually remarks to Amanda that he'd taken up swimming. It comes in useful when the group are attacked on the river by the Spinosaurus.
  • Disney Death: He seemingly falls to his death from a crane, but hilariously turns out to be okay.
  • The Everyman: Despite initially posing as a millionaire, he's more of an average joe and moderate businessman who owns "Kirby Paint and Tile Plus". He has very few skills that are useful when trapped on an island with dinosaurs.
  • First Father Wins: It's heavily implied that he gets back together with Amanda after escaping the island with her and Eric.
  • Papa Wolf: He might be a Bumbling Dad, but he's still a Dad. He expends enormous resources to find his son, willingly going through absolute hell to save him. This includes hiring mercenaries, tangling with dinosaurs on a hostile island, and being alone for long periods with Amanda.
  • Relationship-Salvaging Disaster: A few brushes with death helps push Amanda and Paul back together.
  • Took a Level in Badass: Paul is just a schlubby, divorced small-business owner. By the end, he's taken on a Spinosaurus and survived.
  • Working with the Ex: He's actually divorced from Amanda, despite them putting up a pretense when meeting Alan. They still snipe and bicker with each other; Amanda is slightly more vitriolic than him, however.


Amanda Kirby
"This is how you make dinosaurs?"
Played By: Téa Leoni

"We're not leaving without our son."

Paul's ex-wife who accompanies the group to Site B, feeling guilty for having lost Eric and Ben.


Eric Kirby
"The closer you get to the water the bigger things get."
Played By: Trevor Morgan

"I read both of your books. I liked the first one more. Before you were on the island. You liked dinosaurs back then."

The 12-year-old son of Paul and Amanda who ends up stranded on Site B for eight weeks, and must fend for himself.
  • Action Survivor: He survived a crash that killed his mother's boyfriend and spent the next 8 weeks surviving on an island of dangerous animals completely alone.
  • Giving Them the Strip: He abandons his jacket to escape a swarm of baby pteranodons. Subverted because it works for about half a second before they go after him again. Plus they can fly.
  • Noodle Incident: How he got the T. rex urine is never explained in the film or in the young adult book that tells of his 8 weeks on the island, Survivor. Seeing as how the book is written from his point of view its possible he left some of the more embarrassing situations out.
  • Wise Beyond Their Years: He's very practical for a kid his age, understandable considering he had to dodge dinos for over eight weeks. This makes him the only useful member of the Kirby family for much of the film.

Kirby's Mercenaries


"Nothing to worry about, sir. It's gonna be a walk in the park."
Played By: Michael Jeter

"If we split up, I'm going with you guys."

A meek but sardonic mercenary "booking agent" who travels with his two associates to the island when the man who was supposed to go falls ill.
  • Butt-Monkey: Nothing good happens to Udesky. He's trapped on an island full of deadly animals with a very annoying couple, gets tortured and killed by the raptors, and he isn't even a real mercenary. Hell, he wasn't even meant to be here today!
  • Cruel and Unusual Death: The raptors cripple him and leave him to lie in agony as bait to lure out the protagonists. When they realise the humans didn't fall for their little trap, they snap his neck.
  • Deadpan Snarker: He's one of the more sarcastic characters; it's the only way to stay sane around the Kirbys.
  • Exact Words: Not himself, but how the Kirbys interpreted some of his advice. He told them they needed someone who had been on the island before in order for them to be able to search for Eric (and avoid the dinosaurs). He did not tell them to lie to and trick someone into coming to the island and effectively end up kidnapping them. When he finds out about this, he is not happy. For bonus points, they didn't check their facts, and mistook Grant's experience on Isla Nublar for him being on Isla Sorna before.
  • Forgotten Fallen Friend: Grant never asks what happened to him or even notices his absence after he reunites with the group. He does in the junior novelization, though, but that's only because the book is told mostly from Grant's P.O.V. Consequently, the entire scene where Udesky dies isn't in it and so the reader has to learn of it by having Grant ask where he is and be told about the raptors' trap.
  • Mauve Shirt: Udesky exists largely to be killed to re-establish the raptors as a genuine threat, and dies accordingly. He gets more character than Cooper or Nash, however.
  • Nice Guy: Udesky is a rather polite man and isn't quite a ruthless mercenary. He reveals he wasn't supposed to go along as he's more like the booking agent of the small mercenary outfit and was filling in for another unseen mercenary who called in sick.
  • Only Sane Man: Mixed with Unfazed Everyman.
  • Suspiciously Similar Substitute: To Eddie in The Lost World: Jurassic Park.


Played By: John Diehl

A tough and quiet mercenary.
  • Alas Poor Jerkass: He's unpleasant, but not a villain. It's also hard not to feel sorry for the poor guy, betrayed by his cowardly friend and begging to be rescued as death approaches.
  • Cool Shades: He's seen sporting them on the plane, adding to his stoical demeanour. He notably lacks them after trying to escape the Spinosaurus.
  • Deadpan Snarker: Cooper has a rather sardonic sense of humor, as we find out on the plane:
    Udesky:Cooper! If you see anything, yell up!
    Cooper: Naw, I thought I'd keep it to myself!
    • And:
    Billy: How do you know the Kirbys?
    Cooper: Through our church.
  • Jerkass: He's needlessly sarcastic, seems pretty trigger-happy and knocks out Grant despite there being little need to.
  • Not So Stoic: Most of the time, he has a bored expression and a dry wit. When the Spinosaurus comes for him, his tough guy exterior melts away.
  • Tears of Fear: When trying to escape the Spinosaurus, he jumps in the path of the plane, begging them to stop and weeping when it's clear they won't.
  • Those Two Guys: With his pal Nash, who he calls 'Nashie'.
  • The Worf Effect: After establishing himself as rather formidable, having knocked out Grant, he's swiftly eaten by the Spinosaurus.
  • The World's Expert on Getting Killed: Cooper is supposedly a highly recommended and experienced mercenary. He's the first mercenary to be killed, not long after Udesky claims that, 'Cooper's a professional. He can handle himself'.


M.B. Nash

Played By: Bruce A. Young

Kirby's mercenary pilot.

Other Characters


Billy Brennan
"I don't remember that one being on InGen's list."
Played By: Alessandro Nivola

"That was Isla Nublar. This is Isla Sorna — Site B."

A young and overenthusiastic graduate student at Grant's dig site. He accompanies Grant to Isla Sorna and gets stranded on it with him and the Kirby's.
  • Alliterative Name: Billy Brennan.
  • The Atoner: As opposed to Nick van Owen, Billy knows what he did was wrong and caused a death and seeks to make up for it by saving Eric, even if he dies in the process.
  • Chekhov's Hobby: He mentioned being a proficient paraglider.
  • Disney Death: He's seemingly pecked to death by a pair of Pteranodons but somehow manages to survive.
  • Heroic Sacrifice: Subverted, he manages to survive his encounter with the blood-thirsty dinos.
  • Nice Job Breaking It, Hero!: Billy's theft of raptor eggs leads to numerous dangerous situations, ultimately resulting in Udesky's death.
  • Not Quite Dead: Again, seemingly killed by Pteranodons, still alive afterward.
  • Reckless Sidekick: To Dr. Grant. You don't get much more reckless than stealing Velociraptor eggs.
  • Redemption Earns Life: After inadvertently causing Udesky's death, he very nearly kills himself to save Eric, and is seemingly killed by Pteranodons, making it look like a case of Redemption Equals Death, but then he turns out to be alive on the rescue chopper.
  • Suspiciously Similar Substitute: To Nick in The Lost World: Jurassic Park.
  • Unexplained Recovery: After being supposedly killed by the Pteranodons, Billy turns up alive on the rescue chopper. It isn't explained how he survived the attack, escaped the aviary, made it all the way across the island with his injuries and got to the rescue chopper before the others.
  • Well-Intentioned Extremist: He steals raptor eggs, inadvertently getting Udesky killed.
    Billy: You have to believe me, this was a stupid decision but I did it with the best intentions.
    Grant: With the best intentions? Some of the worst things imaginable have been done with the best intentions. You know what, Billy? As far as I'm concerned, you're no better than the people that built this place.


Ben Hildebrand

Played By: Mark Harelik

"Make sure you get as close as you can! I'll give you something extra if you make it a good trip!"

Amanda's boyfriend.
  • Body Horror: There's really not much left of the guy when they find him.
  • Forgotten Fallen Friend: Despite being Amanda's boyfriend, she isn't overly concerned that he met a horrible fate. She screams when she sees his corpse, but that's her default reaction anyway. She then tells Paul she's not upset about Ben, but about her son, who's still missing. Justified in that any good parent is going to care more about their child then their short-term lover.
  • Peekaboo Corpse: Say hi to your boyfriend, Amanda.


Enrique Cardoso

Played By: Julio Oscar Mechoso

"Hey, I'm gonna get you close, my friend, but not too close, eh. You don't want to be eaten."

A Costa Rican boat captain who operated an illegal parasailing trip around Isla Sorna called Dino-Soar.
  • What Happened to the Mouse?: Exactly what happened to Enrique is a point of contention among fans. It's understood that he dies, but how? Word of God is that some Pteranodons killed him, but it seems odd that Ben and Eric weren't also attacked when they were high in the air. Another theory is that the Spinosaurus killed him, since it's shown as a powerful swimmer but Enrique was out relatively far from the island.

The Dinosaurs


"Obviously a super-predator."

Billy: That's a Tyrannosaurus.
Grant: I don't think so. It sounds bigger.

A super-predator that InGen secretly cloned on Isla Sorna. Very likely to have been the hybrid that Dr. Wu mentioned as having been left on the island, according to promotional material for Jurassic World.
  • Always a Bigger Fish: It kills the Tyrannosaurus rex after it starts to pursue the heroes.
  • Animals Not to Scale: The 44-feet long monster in the movie is actually shorter in length than the real animal! And ironically taller than the real animal, according to 2014 studiesnote . The length part might be justified if this animal is not yet fully grown, as it is currently unknown how long it has been on Isla Sorna prior to the events of this film.
  • Big Bad: It's the biggest carnivore on the island and the most threatening creature the team faces.
  • Breakout Villain: The most memorable thing this movie did was to put Spinosaurus on the map.
  • Cerebus Retcon: Possibly done in World. When it appeared in III, it was thought of as just another one of InGen's cloned dinosaurs that went loose after the island's breeding facilities were abandoned, deadlier yes, but still a normal dinosaur (relatively speaking). However, the official website of World implies it to be one of the hybrid projects that Dr. Wu created in cooperation with Hoskins. Specifically, hybrids that are designed to be much more powerful and intelligent than normal dinosaurs. This is probably why it goes through so much trouble in hunting the humans, and why that poor Tyrannosaurus gets offed so easily. As shown in World, it takes six dinosaurs in totalnote  to bring a hybrid down.
  • The Croc Is Ticking: Paul Kirby's satellite phone is still ringing in its belly... somehow.
  • Giant Swimmer: It can hunt the group in the water as well as on land. Nowadays this is considered its main hunting method.
  • Historical Badass Upgrade: The real Spinosaurus, despite being huge and powerful, preferred to eat fish over red meat (but would have eaten both, if it got the chance. After all, when you are aquatic you get to have more chances at a fish). Here, it's depicted as the ultimate superpredator who eats T. rexes for breakfast. It could have killed a T.rex, but on land it was just as likely to be killed. This is however justified if this dinosaur is a hybrid; hybrids are designed to be deadlier than the real thing. For example, the Spinosaurus survived being bitten in the neck by a T.rex and the I. rex survived getting hit in the head by the tail club of an Ankylosaurus. In real life, both of these events would have almost certainly been fatal to a large predator.
  • Historical Villain Upgrade: Jeez did they make this thing into a monster! Much like the raptors in the previous two movies, it comes off less as an animal acting on instinct and more like a bloodthirsty serial killer. If it is indeed a sister project of the I. rex, then it might as well be a serial killer. The I. rex does hunt other beings for sport.
  • Kaiju: Pretty much what it's been turned into.
  • Karma Houdini: It flees at the end of the final confrontation after getting burned.
  • Never Smile at a Crocodile: It has jaws like a crocodile, just like the real deal.
  • Non-Malicious Monster: Averted. This thing is almost sadistic in the way it hunts the main characters and seems to go out of its way to specifically target humans. Considering that the Spinosaurus on Isla Sorna may have been one of the hybrids that Dr. Wu created, then this is not far from truth, as its sister I. rex also has a thing for humans.
  • Prehistoric Monster: It doesn't so much act like an instinctual animal as opposed to menacing the humans apparently out of malice. The same humans who shredded part of its hide with an airplane's propellers.
  • The Sociopath: This thing is disturbingly vicious, and continues to chase after the humans even when the T. rex it killed would have kept it fed for a month. [[spoiler: Seeing how the I. rex killed off a whole herd of Apatosaurus in Jurassic World for sport and didn't eat them, then it's very likely the Spinosaurus is a hybrid.
  • Stock Dinosaurs: Became stock after this movie.
  • Super-Persistent Predator: To the point that this particular Spinosaurus used to be the page image. Previous dinosaur antagonists usually had plot-based reasons for following their human quarry, or only encountered them by coincidence. The Spinosaurus on the other hand hunts and stalks the group throughout the movie, following them for far longer than it reasonably should. Possibly justified, considering it may be a hybrid like I. rex.



Amanda: For what?

A roost of pterosaurs that live within a gigantic birdcage on Isla Sorna.
  • Adaptational Badass: In the books, the pterosaurs of Jurassic Park still had grasping talons but were too weak to lift Lex (a small child). Here they're capable of carrying full grown adults to their doom.
  • Adaptation Species Change: According to the Jurassic Park books, Jurassic Park had no Pteranodons. The park's token pterosaurs were Cearadactylus (erroneously referred to as "Cearadactyls")
  • All Flyers Are Birds: Possibly invoked.
  • Animal Gender-Bender: All of them have huge crests on their heads, despite the fact that in real life only male Pteranodons had large crests. Yet again, it could just be a manipulation of their DNA on InGen's part to make the female Pteranodons appear more formidable and eye-catching to potential park-goers.
  • Breakout Villain: Moreso than the Spinosaurus even. They were advertised just as much, but much less polarizing to the audience.
  • Death Glare: One of them gives this to Grant.
  • Giant Flyer: About the only accurate thing about them is their massive wingspans.
  • Kidnapping Bird of Prey: Poor Eric.
  • Killer Rabbit: The babies. They're so cute! And oh so deadly...
  • Historical Badass Upgrade: Much stronger and scarier than the real animal.
  • Historical Villain Upgrade: The real life Pteranodon was about as dangerous as a super-sized pelican (though then again...), but these ones are depicted as vicious human-killing predators.
  • Non-Malicious Monster: Much like Rexie in the first film, the Pteranodons were only attacking the group because they were hungry and/or wanted to protect their turf.
  • Ominous Walk: The first one we see does this after landing on the bridge Eric was standing on. Amusingly, an animal known for its flying prowess is introduced by walking menacingly.
  • Ptero Soarer: Probably justified because of the cloning process messing with their DNA. At least they're quadrupedal (unlike the Pteranodon from the previous movie).
  • Put on a Bus: They fly away at the end of the film. The next film reveals that Hoskins killed them.
  • Stock Dinosaurs: Not a true dinosaur, but the most iconic of the pterosaurs.
  • Toothy Bird: While many pterosaurs had teeth, Pteranodon (who's name means "Toothless wing") was not one of them.
  • Zerg Rush: The babies attack in this way.

    Tyrannosaurus rex 

Tyrannosaurus rex

A young adult Tyrannosaurus rex who is defeated by the Spinosaurus.
  • Demoted to Extra: After having a starring role in the franchise, here it exists essentially to be killed and replaced by the Spinosaurus.
  • Neck Snap: How the Spinosaurus kills it.
  • The Worf Effect: 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.



Paul: What are you doing? Those things are after us because of those!
Grant: Those things know we have the eggs. If I drop them in the river, they'll still be after us.
Paul: What if they catch us with them?
Grant: What if they catch us without them?

A pack of Velociraptors that inhabit Isla Sorna and have claimed part of the interior as their territory.
  • Action Girl: The alpha female, who is clearly the matriarch of her pack.
  • Big Bad: For once, averted. This time, they have a good reason for their attacks and don't do any more than is necessary to retrieve their stolen eggs. Everything they do is out of parental retribution and it's likely that they would've left Grant's group alone once they were out of their territory.
  • Feathered Fiend: Partially feathered anyways, though the males have more feathers than the females.
  • Foil: To the original park's raptors. Unlike the Big One, this pack's alpha female is shown to be level-headed and pragmatic, only pursuing Grant and co. to retrieve her stolen eggs. No aggressive behavior is displayed between pack members and they don't appear to be any more malicious than you would expect of their particular species. Overall, they're a well-adjusted and functioning family group, in stark contrast to the first film's psychopathic and Ax-Crazy trio.
  • It Can Think: The smartest iteration of the raptors so far. It's implied that these ones have slowly adapted to surviving in the wild, live in complex family groups, and don't kill packmates for the hell of it, functioning much more like their ancestors than the original park's isolated and sociopathic pack.
  • Mama Bear and Papa Wolf: Their motivation. Like the T. rexes in the second film, the raptors would've just stayed in their own territory and far away from humans if nobody had bothered their babies.
  • More Deadly Than the Male: Implied, seeing as the alpha male appears to be second-in-command to his mate, who is implied to make most of the decisions between them.
  • Non-Malicious Monster: All they want is their eggs.
  • Number Two: The alpha male, to his mate.
