Visitors to Jurassic Park
Dr. Alan Grant
- Adorkable: When geeking out over dinosaurs, to the point that his excitement occasionally leads to him being distracted from potential danger. For example, in the middle of him and the kids being attacked by a flock of bad-tempered pterosaurs, he takes a moment to internally Squee! over the realization that they're quadrupedal.
- Badass Beard: Inspired by the real Dr. Robert T. Bakker.
- Badass Bookworm: He kills three raptors, using his wits. The first he tricks into eating a poisoned egg, the second is wounded by the dying first, and the third is directly injected with poison.
- Cool Old Guy: See above.
- Determinator: And how! Once he got lost in the desert when his truck fell into a ravine. He broke his right leg and had no water, but walked for four days until he found his way back to civilization (as a rule of thumb, human beings can survive three days without water).
- Friend to All Children: Grant has a fondness for kids, finding their love for dinosaurs endearing. He gets on very well with Tim and Lex. Interestingly, he starts the first JP movie as a bit of a Child Hater but grows out of it as the film goes on.
- Only Sane Man: Alternates the role with Malcolm and Gennaro.
- She Is Not My Girlfriend: With Sattler. This is very literal because Sattler 1) is his assistant and student (and he sees it as wrong to see her in that way) and 2) going to marry a doctor in Chicago. He also mentions at one point to have been married (but is currently a widower).
- Walking Tech Bane: Doesn't particularly like or understand computers.
Dr. Ellie Sattler
- Action Girl: Outruns, outsmarts, and fights off various Velociraptors, The Dreaded among the Park's dinosaurs.
- Bare Your Midriff: She wears a midriff-bearing outfit for most of the book.
- Hot Scientist: Ian Malcolm and Donald Gennaro certainly think so. See "Who Wears Short Shorts."
- Idiot Ball: Briefly carries it when she is attempting to distract the raptors. Wu repeatedly demands she come inside in a panic but Ellie, who up until this point had been sane and rational, keeps declaring that she knows what she is doing and doesn't get what the problem is. This leads to Wu dying and Ellie herself almost being killed by the raptors.
- The Lad-ette: One of the first things we see her do in the book is chug a whole can of beer.
- Ms. Fanservice: More or less all the male characters comment on her to themselves privately.
Ian: You're extremely pretty, Dr. Sattler. I could look at your legs all day.
- Or out loud, in the case of Ian Malcolm.
- She's Got Legs: Ian Malcolm and Tim Murphy both take note of them.
- Took a Level in Badass: Well, fighting off two Velociraptors qualifies her for this trope.
- Who Wears Short Shorts?: Ellie does. Lampshaded when Gennaro offers to stay with Ellie and Harding when they stop to investigate the sick Stegosaurus on the tour.Malcolm: Why would our dear lawyer stay behind?
Grant: Probably because of Dr. Sattler.
Malcolm: Hmm. The shorts, you think?
Grant: It's happened before.
Dr. Ian Malcolm
- Brutal Honesty: Several times. It's one of the reasons Hammond doesn't like him.
- Breakout Character: As played by Jeff Goldblum in the film adaptation, he was so popular — and, conveniently, Spared by the Adaptation — that his death is retconned in the next book, The Lost World, so he can be the protagonist.
- Cloud Cuckoo Lander: Especially while high on morphine.
- Cool Shades: Wears them.
- Deadpan Snarker: Sometimes.
- Dented Iron: Survives being bit and flung away by the T. rex. His injuries, however, made him bed-bound for the rest of the book and complications from them (temporarily) kill him off for real.
- Ignored Expert: Hammond hires him to predict the park's future, using mathematical models. Malcolm comes to the conclusion that the park will unavoidably collapse, but Hammond refuses to believe him.
- Jerk with a Heart of Gold: Is insensetive and a little obtuse, but is a nice guy deep down.
- Killed Off for Real: Dies from rex-inflicted injuries and their complication by lack of treatment (by a real doctor-Harding, as the Closest Thing We Got (a vet), does his best, but he couldn't do enough for him) by the end of the book. His status as a Breakout Character and being Spared by the Adaptation in the film had him upgraded through Retcon to having been Only Mostly Dead and having recovered by the events of The Lost World.
- Mad Mathematician: For a given value of "mad". (He cheerfully calls himself "mad as a hatter"). His field of research is chaos theory, and many of his filibuster speeches throughout the book are pretty much about how the park is doomed because dinosaurs are a gigantic unknown factor.
- Meta Guy: Mildly.
- Only Sane Man: Shares the role with Grant and Gennaro.
- Southern-Fried Genius: A Texan, he is one of the best mathematicians.
- Tall, Dark, and Snarky: Yup. He explains early on that he only wears black and grey clothes so that he never has to waste time deciding what to wear.
- Amoral Attorney: Averted. Gennaro is no saint, and to some degree, he's responsible for the catastrophe, but he's far from being evil.
- Bus Crash: Dies between Jurassic Park and The Lost World from a bout of dysentry.
- Cowardly Lion: While he's clearly afraid when he hears that the raptors escaped, he pulls himself together and goes to help Muldoon to fight them.
- The Everyman: Serves as the "token normal" in the cast.
- Jerk with a Heart of Gold: Variant. Borderline Dirty Coward that continuously whines about the dangerousness of the situation and understandably doesn't wants to risk his life if he doesn't see the need (Grant has to strong-arm him into coming along to find the raptor nests, for example, once the park is back online), but still works on trying to put the park back in function so rescue can be called, and is determined to check the park's functionality with a magnifying glass when he first arrives because he agrees with his firm's beliefs that Hammond is either full of crap or working on very dangerous stuff.
- Only Sane Man: Has his moments.
- Took a Level in Badass: Namely, in the part where a Velociraptor pounces on him, and he stands up and flings the bloody beast off him!
Alexis "Lex" Murphy
- Annoying Younger Sibling: To Tim. She is a whiny and irritating tomboy who is more interested in sports than dinosaurs (in fact, she hates them), and she teases Tim about his love for dinosaurs. (Tim thinks she's being particularly obnoxious because she's upset over the divorce of their parents.)
- Bratty Half-Pint: And how. Not only she complains all the time (even before things go wrong with the park), she acts as self-righteous or then cries, teases her brother about liking dinosaurs (even going to the point of saying he's not their dad's favorite kid as if it's nothing) and at times disregards Dr. Grant's instructions even after it almost gets her killed.
- The Chew Toy: If something is large and carnivorous, expect her to alert it into attacking her..
- Fluffy Tamer: For some bizare reason, she is the only one who can approach the young raptor (who she names Clarence) they found. She also befriends a young Triceratops they meet (whom she names Ralph).
- The Load: Does not particularly do anything important, aside from a brief Fluffy Tamer moment with a young raptor.
- Tomboy: Lex is a big baseball fan and her best relationship is with her father.
- Tomboyish Name: Alexis, while considered to be internationally male, is a popular tomboyish name in America.
Timothy "Tim" Murphy
- Big Brother Instinct: Though he finds Lex annoying, he still tries to protect her when there is danger.
- Hero-Worshipper: He's a huge fan of Dr. Grant.
- In-Series Nickname: Lex calls him Timmy and everyone else calls him Tim.
- Male Gaze: He checks out Ellie's legs.
- Playful Hacker: In addition to his love for dinosaurs, he is also computer-savvy. This becomes useful when the park's computer system needs to be rebooted and all of the adults are busy fending off raptors. In the film, this was given to his sister Lex as to prevent her from being The Load like her novel counterpart.
- The Un-Favourite: His backstory regarding his parents, especially his father. The man is a hard-core sports fan and Tim's pursuits are not sports-related (especially his dinosaur obsession-his father flat-out dismisses it as kids' stuff and only gives a token glancing at the exhibits of a museum that they are visiting of a flashback), while Lex is a baseball-loving tomboy. Played with in that not only does Lex, later in the book, assure him that their Dad does love him too, but an earlier scene recounts Tim realizing that the museum they saw a T. rex in had the wrong number of vertebrae in it. Tim's Dad is genuinely impressed that Tim knew that (after checking the facts with the nearest security guard).
Jurassic Park Staff
- Asshole Victim: His death is well deserved.
- Bad Boss: Treats his employees with derision when they say what he doesn't want to hear.
- The Barnum: Has shades of this, being mentioned to be very much a showman. His backstory with the flea circus and his tactics to bring sponsors to the Jurassic Park project (which included bringing along a one-of-a-kind and (unknown to the sponsors) highly fragile dog-sized elephant to showcase the wonders of genetic engineering) are good examples.
- Big Bad: He's the main human antagonist of the novel thematically, being the CEO of InGen and creator of Jurassic Park. Virtually all of the problems that happen in Jurassic Park can be traced back to Hammond's decisions, from the insistence of displaying "real" (but dangerous) dinosaurs over the safe "domesticated" version to the over reliance of the park's automation system to the inadequate security measures meant to keep visitors safe from the dinosaurs (as well as keeping the dinosaurs from escaping the island, including Muldoon's requests for extra and more powerful weapons). Even Nedry's betrayal that kickstarts the main incident can be linked to Hammond blackmailing him to work overtime on the park's automation program and being underpaid. He is determined to open Jurassic Park one way or another (even after the disaster had made it virtually impossible) in order to make his dream of bringing joy and wonder of dinosaurs to the children of the world... so he make a profit off of them. If you can't afford it, well... there's nothing he can do.
- Corrupt Corporate Executive: And how! The man made Cutting Corners an important part of his plans to create the park: high automation to not have to pay much in personnel costs, short-changing the man who created the automation program, and using a DNA reconstruction process that was bound to create mutations (like making the dinosaurs fertile) but was cheaper in time and money are three examples. He was also not above defrauding investors and using blackmail on employees he had undersold the job to, either. Or potentially endangering people (he vetoed Wu's idea of using just tame, herbivorous dinosaurs for the park, insisting on wanting a "real experience" with the dinos).
- Cutting Corners: Does this all the time because he thinks it will save money. It just causes more problems for him and the people around him.
- Eaten Alive: He is completely paralyzed by Procompsognathus' venom by the end of the book, but is still blissfully aware of the compys on top of him nibbling his fingers and neck.
- Fatal Flaw: Greed. To the point he is more worried about the safety of the dinosaurs then people endangered by them because they cost so much money to make.
- Faux Affably Evil: He can be charming and charismatic, but he's prone to fits of childish rage whenever things don't go his way. He also has a tendency to blame others for his mistakes, treat his employees with derision when they try and tell him what he doesn't want to hear, and he'll happily stoop to blackmail and cost-cutting to get what he wants.
- Friend to All Children: Hammond claims that Jurassic Park was primary meant for children and that he couldn't wait to see the look on their faces when they see real live dinosaurs for the first time. It's subverted, once it turns out that Hammond only cares about making a profit off the rich and only brought Tim and Lex as means to convince Gennaro from shutting down the park. By the end of the novel, he curses own his grandchildren for being nothing but trouble after he broke his leg fleeing from recorded T. Rex call that Tim and Lex were playing at the control room.
- Hoist by His Own Petard: All of his actions come back to bite him in the ass. To wit:
- His recruitment of Henry Wu leads to the creation of incredibly flawed dinosaurs because Wu doesn't know as much about them as he should and is just as unwilling to admit his mistakes as Hammond is - although, at least Wu knows that making Carnivores was a terrible idea.
- He blackmails Dennis Nedry into creating a massive automated security system for an unfairly low pay, leading the understandably embittered Nedry to do a sloppy job out of spite and later attempt corporate espionage for a rival company, shutting down the park and letting the animals escape in the process.
- His decision to rely completely on automated security (because he doesn't want to pay a security team to patrol the island) results in several compys escaping on board a supply boat via the jungle river because it isn't monitored. This leads to several attacks on the mainland, which prompts his investors to demand an inspection of the park to ensure its safety.
- He brings his grandchildren to the island because he thinks their presence will deter Gennaro from ordering the park's destruction. Near the end of the book, they get into the control room and start fooling around, which causes Hammond to suffer a severe leg injury that prevents him from fending off a pack of compys when they attack him.
- Jerkass: In stark contrast to the film's version, Hammond comes off as an obnoxious, greedy man who bluntly ignores any criticisms to his park and quick to blame everyone but himself for any of its shortcomings or problems.
- Jerkass Has a Point: He does point out that Arnold and Wu's failings (as detailed below) were largely responsible for the downfall of the park.
- Wu's obsession with improving on the creatures he had made, using a reconstruction process that was bound to create mutations, leading to the issue with the dinosaurs breeding in the first place; his anger at Wu when he finds out the dinosaurs are breeding is justified.
- Arnold's worrying about trivial things (such as the gearshifts on the Landcruisers not working) led to serious problems being ignored.
- Jerk With A Heart Of Jerk: His one redeeming quality appears to be his love for his grandchildren, only for it to be revealed the reason he brought them to the island was to use them as emotional blackmail if Gennaro tried to shut down the park. He knowingly put his grandchildren at risk just to keep the money flowing.
- Karmic Death: Dies at the hands (or, rather teeth) of a pack of compys (the first dinosaurs to get off the island, the discovery of which kick-started the the plot).
- Manipulative Bastard: Managed to convince the Costa Rican government, Grant, Sattler and even his own grandchildren that he was entirely trustworthy. He's not.
- Never My Fault: Near the end of the book, Hammond has a long internal monologue, where he blames everyone except himself for the disaster.
- Amusingly, his excuses for why certain people were at fault grow more and more flimsy as he goes on. . . but pretty much every single one is valid, which says something about Hammond himself that he hired these massive screw-ups because he honestly believed (at the time) that they were the best men for the job.
- Only in It for the Money: In a conversation with Wu, Hammond outright says that the goal of InGen is to make money above all else.
- Screw the Rules, I Have Money!: The "rules" being the biological and technological drawbacks of the park, some of which are inherent, others by deliberate cost-cutting. Hammond is utterly convinced that he can interpret the reality of the park disaster any way he wants, simply because he's the one writing the cheques.
- Villainous BSoD: Has one after everything hits the fan.
- Vast Bureaucracy: Hammond also says he doesn't want to use genetic technology for the benefit of mankind (such as creating better drugs) because that activity is monitored and regulated and restricted by governments to the point where the end product may never even reach the people who need it and there's no real profit margin in it anyway. Genetic technology used for the entertainment industry however, is not regulated by anyone at all.
- Visionary Villain: Zig-zagged. Whilst he states that his dream is to see the entire world watch in awe at dinosaurs, it's clear he merely plans to make a profit of the rich. He states to Wu during their bungalow dinner conversation that he has already made plans to build Jurassic Park Europe and Jurassic Park Japan shortly after Jurassic Park is open to the public. However, his sinking into depression after everything hits the fan and his discussions with Malcolm after that indicate that some of his vision may have been genuine.
Dr. Henry Wu
- Asian and Nerdy: As if his last name didn't tip you off.
- Break the Haughty: His ego and sense of always being right are damaged severely when he is given strong evidence that the dinosaurs are breeding, and both are wrecked beyond repair when he is given total confirmation of it, to the point of feeling that everything about the park is called into question.
- Character Development: He starts out rather smug, but when he's forced to accept the fact that the dinosaurs got around his failsafes to keep them from breeding, his arrogance goes out the window.
- Cruel and Unusual Death: Not quite as bad as Nedry's, but he's still Eaten Alive.
- Death by Irony: One of the raptors he created eats him.
- Eaten Alive: After being attacked by the raptor, Wu desperately tries to push the raptor's head away from his body not realizing he's already been disemboweled and the raptor is now eating his guts.
- Fatal Flaw: Pride.
- Gone Horribly Right: His view of the events. Sure, the dinos are deadly and are breeding, but that means he recreated them successfully, right? Technically, this is true.
- Ignored Expert: Wu knows that the cloned dinosaurs are not really real, merely constructs of one version of the past, and that he could genetically modify them to be slower and docile. He purposes to Hammond that this direction would make the park safer and fit people's expectations of tail-dragging, sluggish reptiles.note Hammond rejects it, believing that the dinosaur clones are "real" and should be "real," completely missing the point altogether.
- Insufferable Genius: Rather smugly shoots down Grant and Malcolm's doubts about the quality of his modifications.
- Mr. Exposition: A role he shares with various other characters regarding the park. His bigger focus is explaining the science behind the dinosaur cloning.
- Never My Fault: Like Arnold, he points out there are mistakes, yet he never admits his role in them.
- Smug Snake: While not necessarily a full-on villain, he repeatedly insists that his genetic modifications to the dinosaurs are infallible and the way he reacts when Grant points out that the dinosaurs are breeding would have you think that any failure in the system is a completely alien concept to the guy.
- Too Dumb to Live: Wu gets munched by a raptor while standing just outside the wide-open door of the Visitor's Center, yelling for Sattler to get inside. He does this knowing that the building is under siege by raptors at the time. Muldoon's narration privately comments on how stupid he's being, but the raptor beats him to the punch before he can say anything to Wu.
- Eaten Alive: He is pinned down and mauled by a raptor in his attempt to start up the power generator.
- Everyone Has Standards: His backstory was that he used to build nuclear missiles for the Navy, but could no longer stomach doing so after his first child was born.
- Good Smoking, Evil Smoking: He is described to be a chain-smoker.
- Mr. Exposition: A role he shares with various other characters regarding the park. His bigger focus is on the systems that run the park.
- Failed a Spot Check: He failed to notice that, when they initiated the reboot, only the auxiliary power kicked in, not the main generator. By the time he does notice, the park is literally seconds away from losing power again.
- Mr. Fixit: His role alongside Nedry, at first. Once Nedry's bug starts to make the park's systems go haywire (and then he dies), most of Arnold's screen time is him trying to make the park work again and be Mission Control to the people on the field.
- Never My Fault: Points out that there are problems, however, denies he has any role in them.
- Tempting Fate: After a couple of tense hours fixing Nedry's sabotage, he declares they've regained control of the park. Then the auxiliary power fails...
- Too Dumb to Live: He might have survived and even saved the day early on had he not used his shoe as a doorstopper to let a little light in the maintenance shed (because an underground building during a power outage won't have any lights inside). One of the raptors notices the shoe and immediately picks up Arnold's scent inside the building.
- The Alcoholic: Yup, he's a notorious one on the park. Which is not helpful when chasing down a T. rex or putting down Velociraptors.
- Awesomeness by Analysis: Thanks to his background as a safari hunter and consultant, Muldoon is able to piece together the scene of an attack with great accuracy. When investigating the aftermath of the T. rex breakout, he deduces that the kids are still alive and have fled with Grant deep into the park contrary to what Gennaro initially believes. He likewise figures out that Dilophosaurus were the ones who got Nedry as opposed to the compys scavenging his corpse, and where Rexy is heading.
- Badass Mustache: A steel gray mustache to be precise. And unlike the film, he's badass enough to survive the whole ordeal.
- Drowning My Sorrows: Several times, likely due to the stress caused by dinosaurs breaking out of their cages and killing the employees.
- Drunken Master: Is an alcoholic, yet he can still take down Velociraptors.
- Great White Hunter: Sort of. He used to be a guide for big game hunters in Africa, but went on to work for conservation groups and zoo designers as a wildlife consultant.
- Icy Blue Eyes: He has deep blue eyes and a cold, cynical attitude towards dinosaurs.
- Ignored Expert: As warden of Jurassic Park, Muldoon has been calling for heavier reinforcement and weaponry than what he's been provided, citing how dangerous and unpredictable these dinosaurs could get. Hammond ignores most of these requests and only relents on bringing in one lethal rocket launcher when Muldoon threatens to quit and expose the Jurassic Park project. When Rexy breaks into the Apatosaurus paddock, Muldoon gets to chew Hammond for it. He also notes the problems with the park in that they are dealing with animals that haven't existed for millennia, and thus they know next to nothing about them biologically.
- More Dakka: Muldoon demands this after an incident during construction where one of the raptors got loose, killing two construction workers and fatally maiming a third before it was recaptured, noting from his own experience how difficult it is to bring down animals like elephants in the wild, and that some of the dinosaurs in the park are far larger and infinitely more dangerous.
- Nice Hat: Similar to Indiana Jones.
- Only Sane Man: Out of all the prominent park employees, Muldoon is the one who has the most realistic grasp on the situation at hand. Unlike Wu or Hammond, he is under no illusions of what these dinosaurs, especially the raptors, could do, and was the one calling in for higher security (for which Hammond only provides the bare essentials) and unlike Arnold he's physically been through the park and is acutely aware that the security that does happen to be in place can only do so much (especially as it breaks down). The only time when he's not in this mode is when he drinks up till he's drunk during situations like the raptors trying to get in the Safari Lodge. But considering how many people stupidly run to their deaths when it comes to the raptors, perhaps getting drunk is the only sane option.
- Rare Gun: Carries round a rather large one known as M72 LAW. Said weapon which was designed to take out tanks, is the only thing in Jurassic Park's arsenal that can reliably kill a velociraptor in one shot.
- Shame If Something Happened: When park management refused his demands for greater firepower on the island to deal with potential problems, Muldoon blackmailed them into a compromise by threatening to quit and take his story to the press.
- Sole Survivor: Of the core Jurassic Park management, he is the only one that makes it out alive. Justified, as he was the only one who correctly anticipated the danger of the animals (especially the raptors) and acted accordingly.
- Asshole Victim: His death is well deserved, even if he was being blackmailed by InGen. Nobody really feels sorry for him and when Muldoon finds his corpse, he doesn't even bother to pick it up.
- Cruel and Unusual Death: He gets his gut slashed open, and is left holding his entrails before getting his head bitten off.
- Eaten Alive: Nedry is still alive when the Dilophosaurus spills out his guts and puts its jaws around his head.
- Eye Scream: You know he's not getting out of this alive when the Dilophosaurus spits venom in his eyes, blinding him.
- Fat Bastard: He's a fat, overworked computer programmer for the entire system of Jurassic Park and he deliberately sabotages the system to give himself cover to smuggle the dinosaur embryos to InGen's rival for $1.5 million. The fact that his plan would have put many lives in danger (and open Nedry for lawsuit) has never crossed his short-sighted mind.
- Fat Idiot: He's not a complete idiot per say (as he did programmed the entire network as well as creating blackmail material in case his employer Dodgson backs out paying him), but he is really bad with finances and planning ahead. He took Dodgson's offer of stealing the embryos for $1.5 million, not realizing that the embryos are actually worth $2-10 million. He also didn't take in account of the tropical storm affecting visibility on the road, or otherwise he would have chosen a different date to pull off his heist.
- Fat Slob: Hammond and Arnold both refer to him as this.
- Jerkass: He's quite unfriendly to everyone else working in the park.
- Just Desserts: Is torn apart and devoured by a Dilophosaurus.
- Karmic Death: Killed by a dinosaur that would, probably, have not escaped if it were not for his sabotage. When Muldoon and Gennaro find his corpse, Muldoon even remarks: "Maybe there's justice in the world after all."
- Mistreatment-Induced Betrayal: InGen demanded he create a gigantic computer system far more ambitious and time consuming than any project before, and refused to give him the full details of what the system was actually for, leaving Nedry to work in the dark. Inevitably, this leads to glitches and bugs but the company blames Nedry for "poor programming" rather than them not giving him all the necessary details needed to create the system. And top it all off, they refused to pay Nedry extra for all the time it would take untangling the bugs, because from InGen's point of view their were Nedry's fault in the first place. Instead, they began to harass and defame Nedry to his other clients, so Nedry had to swallow the overtime for him and the rest of his company if he ever wanted to work again. It's no wonder that he is willing to steal dinosaur embryos and give them to a rival company for a million and a half dollars.
- The Mole: For Lewis Dogdson. It didn't take much for Dogdson to recruit the best inside-man he could have in Jurassic Park at the cheapest price.
- Nothing Is Scarier: Nedry gets permanently blinded by the venom of Dilophosaurus and the novel describes his death from his perspective. He could sense the Dilophosaurus coming to finish him off through sound, smell and touch but his inability to see renders him helpless to ward off any attack.
- Revenge: He's stealing dino embryos for a rival company because InGen gave him such a hard time when they hired him, such as forcing him to write huge amounts of software without telling him what it was for, demanding software rewrites and patches without paying extra for them, and then blaming all the glitches on him.
- Significant Anagram:
- "Nedry" "nerdy."
- His full name: "Dennis Nedry" = "Nerdy Sinned".
- Smug Snake: He is a rude fellow and full of himself, believing that he could fixed all of the bugs in the Jurassic Park computer system within a weekend only to pale when he saw the full list. He also thinks himself to be a clever planner who thought of every factor in his smuggling operation... except for checking the weather forecast.
- Too Clever by Half: His plan to steal the embryos and made sure that Dodgson didn't backed off from paying him, even if not high on potential "perfect crime" material, was still pretty clever and would have put egg on Hammond's and Dodgson's face. Too bad that he got lost en route to the embryo drop-off point...
- Villainous Glutton: Is very fat, and very villainous.
- Adapted Out: He was in a few early drafts of the movie's script, but ultimately nixed entirely to reduce the number of actors, with his more unpleasant traits given to the film's version of Gennaro.
- Child Hater: He is annoyed at Hammond's insistence that he babysit Lex and Tim, since he felt that he "wasn't a damn babysitter", and he had more important things to do since he was the publicist of Jurassic Park. However he is professional enough that he never takes it out on the kids, and even plays catch with Lex.
- Death by Genre Savviness: Although he considers going back for the kids after hearing Lex, he is concerned that Lex's constant yelling will attract the Tyrannosaur. So he heads in the other direction, only to encounter (and be killed by) the juvenile T. rex that had escaped earlier.
- Dirty Coward: He abandoned Lex and Tim when the Tyrannosaurus rex escaped from its enclosure. In fairness, he does feel ashamed for doing it.
- Everyone Has Standards: Regis is legitimately ashamed of himself for abandoning the kids after the T. rex escaped.
- HeelFace Door-Slam: After realizing how shameful it was of him to abandon the kids, he tries to go back and see if they are alright... only to then change his mind and subsequently get ripped to shreds by the juvenile T. rex.
- Jerkass: And how! Condescending to everyone during the tour (even to the experts), acts like a smug prick throughout, and abandons the kids when the T. rex escapes.
- Jerkass Has a Point: He does at least have a point in that he is the park's publicist and not a tour guide, so however obnoxious he may be, his resentment at having menial tasks forced on him isn't entirely misplaced. He also calls out Grant quite vehemently for manhandling a baby raptor, since at that age they can be quite delicate and essentially die from shock. He's probably thinking more about all the expensive genetic technology that went into making the animal, but he's quite right that Grant has no right perform a full, rough, uncaring physical on it just because he's curious.
Dr. Martin 'Marty' Guitierrez
- Adapted Out: Has the dubious distinction of being the only character to appear in both books but none of the films, since the discovery of the compy remains are absent.
- Decoy Protagonist: One of two during the first act of the novel. Disappears completely once the narrative changes to the other characters and reappears near the end of the epilogue wanting to talk to Grant about the events on the park and the possibility that various raptors had managed to "migrate" out of it and into the depths of the Costa Rican jungle.
- Mr. Exposition: Several times.
Dr. Lewis Dodgson
- Big Bad: Of The Lost World (1995).
- Corrupt Corporate Executive: More so than Hammond, who was at least mildly benevolent.
- Cutting Corners: Dogdson promises $1.5 million to Nedry if he smuggles the dinosaur embryos to BioSyn. Unbeknownst to Nedry, the dinosaur embryos he stole are actually worth $2-10 million in total according to Dr. Wu.
- Eaten Alive: After being thrown into the Tyrannosaurus nest, Dogdson is devoured alive by three T. rex infants. The first infant clamps down on his leg with its jaws; the second leaps on his midriff and goes for the waist; and the third (the infant with the cast leg) tears a good chunk of his flesh from his face. Mercifully, the next bite is around his neck.
- Foil: To Hammond. Dogdson is ultimately the smarter one of the two.
- Faux Affably Evil: Unlike Hammond, any politeness he shows is definitely a facade.
- Greater-Scope Villain: Though he's the reason why Nedry sabotages the park to get the embryos, he disappears from the first novel altogether after his meeting with Nedry and doesn't return until the sequel novel, The Lost World (1995).
- Karma Houdini: In the first book, though he lost out on his investment, he's never busted for his role in the disaster.
- Karma Houdini Warranty: Finally expires in The Lost World.
- Karmic Death: In The Lost World. When he and some minions try to steal T. rex eggs, they break a baby T. rex's leg. Malcolm's team ends up putting the baby's leg in a cast. At the end of the novel, Dodgson gets his leg broken by the baby's parents who are teaching it to kill its own prey.
- He also attempts to murder Sarah Harding by pushing off her a boat to drown her, and when later both are reunited by hiding under a car from a T. rex, she pushes him out to get grabbed by it leading to his above fate.
- Mad Scientist: We are given exposition that explains he invented a variation of rabies that was airborne (allegedly useable as an airborne vaccine) and he unleased it on some unsuspecting townspeople in Chile for testing purposes (which he was not authorized to do, by the way) just to prove it worked. It caused an epidemic instead and his involvement in the plot of both books are him trying to do something to prevent being put on the chopping block.
- The Man Behind the Man: To Nedry.
- Manipulative Bastard: Look at his previous projects (rabies tests, genetically engineered potato)and wonder why he is still in business.
- Meaningful Name: Averted. His name is clearly a portmanteau of the real name and pen name of 19th century mathematician/author Charles Dodgson/Lewis Carroll, but it has no significance beyond that.
- Not That Kind of Doctor: Exaggerated. We eventually are given exposition that says he never even earned a doctorate.
Dr. Roberta Bobby CarterAn American doctor in Costa Rica who treats the first known victim of the dinosaurs.
- Decoy Protagonist: Shes the pov character of the first chapter but afterwards disappears from the story.
Daniel RossGennaros Voss at the law firm getting Hammond investors.
- Honest Corporate Executive: Ross orders Gennaro to pull the plug on the operation and destroy the dinosaurs if theres any sign that their hurting people.
- Know When to Fold 'Em: Ross has a lot of money invested in the park but is prepared to sacrifice it rather than attach himself to a dangerous and/or doomed venture.
- Properly Paranoid: Hes worried that Hammond is either lying or wrong about none of the dinosaurs escaping and hes absolutely correct to feel this way.
Mike, Ellen and Christina Tina BowmanA family from Texas who encounter an escaped dinosaur on vacation and provide one of the first eyewitness descriptions.
- Adorably Precocious Child: Tina is portrayed as a nice little kid eager to draw animals for a school project, although she is capable of recognizing a joke directed at her and pretends not to hear her mother calling her to out in suntan lotion.
- Adult Fear: The pretend are worried by their daughter wandering off then coming back with several bad bite marks.
- Cosmetic Horror: Ellen is described as being unhealthily obsessed with unnecessary plastic surgery in the first place and (unknown to her husband) first wanted to come to Costa Rica for another operation.
- Free-Range Children: Tina is allowed to wander off a beach by herself and is bitten by a dinosaur she finds.
- Hyper-Awareness: Tina has a good memory for details of appearance. She is able to give a very good description of the dinosaur that bit her. While her doctor initially thinks it must be a normal lizard she remembered some details wrong about he reconsiders after she notices that hes wearing a different shirt but the same time the second time he visits the family.
- The World Is Just Awesome: Mike is deeply impressed by the jungles and parks of Costa Rica.
- An EPA agent who interviews Grant about some odd purchases made by Hammond.
Alice LevinA lab tech associated with Grant and Ellie and the first person to suggest dinosaurs in regards to the Costa Rica incidents.
- Always Chaotic Evil: The eight raptors in the holding pen are all equally vicious, eager to pounce on any living thing whenever opportunity shows itself. It's subverted when the survivors discover the nest of the wild raptors. The wild raptors seem to tolerate their presence, to point of ignoring them in favor of finding a ship to get off the island.
- Ax-Crazy: The eight raptors will attack anything on sight, even if they're not hungry. In fact, if they're not pouncing on you on first sight, that means you're already dead.
- Chameleon Camouflage: Some of the wild raptors can change colors, most notably Clarence the male raptor that Grant and the kids discover on their way back to the Visitor Center.
- The Dreaded: The most vicious and dangerous of the creatures on the island. Muldoon believes the raptors to be too dangerous to be kept alive and would have them all destroyed had the park administration not worried about the money lost in these clones.
- For the Evulz: What makes the raptors stand out from other carnivorous dinosaurs is that they hunt even when they're not hungry and they kill for the sake of killing.
- The Heavy: The main dinosaur antagonists of the book, and the ones that cause the most trouble for the protagonists.
- Informed Species: They are officially identified by Dr. Wu as Velociraptor mongoliensis but they bear more resemblance to Deinonychus antirrhopus.
- In-Series Nickname: Often universally referred as "Raptors" for short.
- Made of Iron: A Velociraptor has a distributed nervous system, meaning it doesn't die fast, even with a direct hit to the brain. Its body is solidly built with thick ribs that protects its heart all too well. And it's difficult to cripple the raptor's legs or hindquarters. It's no wonder Muldoon wants rocket launchers on the island.
- Monstrous Cannibalism: Tim and Lex try to use the baby Velociraptor that they previously met back in the lab tour to distract the rampaging adults. They are horrified when the adults tore and ate the poor thing without second thought. Later, when one of the raptors is poisoned by Dr. Grant, it didn't take long for the other raptor to view its hapless companion as food.
- Raptor Attack: Like the film, they're the reason this trope exists in the first place.
- Token Good Teammate: One of them (named "Clarence" by Lex) befriends the heroes.
- Sadists: As Muldoon puts it, the raptors often kill for pleasure and never pass up prey. Some of their victims were found torn to shreds but otherwise uneaten. However, this only applies to the raptors held in captivity.
- Stock Dinosaurs: This book is what made the Velociraptor stock.
- Super-Persistent Predator: Raptors always hunt, even when they are not hungry. And humans are their favorite prey because of how easy it is to kill one. And they will not rest till they've hunted all of humans on the island.
Tyrannosaurus rex ("Rexy")
- Ambiguous Situation: Via retcon from the sequel The Lost World (1995). In original novel, Rexy's inability to see motionless objects is theorized by Grant to be the result of mutation side-effects caused by InGen's amphibian DNA splicing to fill in the gaps. 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 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 to say, no one knows why Grant wasn't killed that night, although Rexy is shown eating a goat in its first appearance.
- Decoy Antagonist: The novel makes it seem that Rexy is the 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 and shortly after her sedation, the park's power shuts down and it's revealed that all electric fences have been off for hours. It's then the readers realize that the Velociraptors, regarded to be even more dangerous than the T. rex, are true dinosaur antagonists of the novel.
- Evil Smells Bad: 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 gorging herself on her freshly killed hadrosaur.
- The Heavy: Aside from the raptors, Rexy is the one who 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.
- In-Series Nickname: Robert Muldoon is the one who calls the adult T. rex "Rexy."
- Living Motion Detector: A side-effect of the amphibian DNA splicing is that Rexy's vision is based on movement. A fortunate mutation 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 poor Baselton finds out.
- Overly Long Tongue: She has one, presumably because of the frog DNA.
- Red and Black and Evil All Over: Her species's primary color here is brick red. And she is follows Grant and the kids to no ends.
- Reptiles Are Abhorrent: Her reptilian qualities are really played up.
- Roar Before Beating: Rexy often roars at her potential prey before going for the kill, likely to make up for its motion-based vision impairment.
- Scary Teeth: To be expected from a dinosaur with teeth like steak knives.
- She Is the King: Even more so than the films. While Rexy's gender in the films has been emphasized to be female, the novel often refers to Rexy as a male, which is lampshaded by John Arnold during the tour of the control room.
- Stock Dinosaurs: THE Stock Dinosaur.
- Super-Persistent Predator: Unlike in the movie, 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.
- Tyrannosaurus rex: The name says it all.
- Uncertain Doom: 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 drowned in the pool she's in after being tranquilized by Muldoon?
- Unwitting Instigator of Doom: 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 the raptors to break free. Additionally, her hunting of Grant and the kids forces them to take the river route, which has no motion sensors to signal back to the control room.
- Family-Unfriendly Death: Their second on-page appearance involves gruesomely averting Infant Immortality, eating a newborn baby's face. By the time the nurse even opens the door, the baby is quite dead.
- In-Series Nickname: Compys.
- Karmic Death: They deliver this to Hammond.
- Killer Rabbit: Tiny and cute, but also deadly.
- Reptiles Are Abhorrent: Double subverted. The little girl who encounters one of them in the prologue is not scared of it at all, in fact she finds it adorable and thinks it would make a great pet. Then it bites her...
- Ridiculously Cute Critter: Though the fact that they kill people and like to eat fecal matter mitigates this somewhat.
- Road Apples: Their job in the park is to clean these up. How? Well how do you think?
- Small Role, Big Impact: They're not very prominent, but their discovery pretty much kick starts the story's plot.
- Zerg Rush: Not as much as the film though.
- Amazing Technicolor Wildlife: Described as having leopard-like spots and brightly colored, parrot-like heads.
- Ambiguous Situation: Grant and the kids encounter a pair of Dilophosaurus performing what seems to be a mating ritual, with one of them having a duller red crest than the other. The problem is that Dilophosaurus are not among the dinosaur species that have Frog DNA, which is how those dinosaurs were able to change sex and breed. Is it really a mating ritual or did life found another way for this pair?
- Artistic License Paleontology: Averted for the most part when compared to the film adaptation. The novel's Dilophosaurus are about 10-feet tall and the tour guide mentions they have weak jaw muscles, which is accurate to the real-life Dilophosaurus. They likely did not have venom in real-life, which is a deliberate invention on Crichton's part; mainly for Rule of Scary and to illustrate a point of just how little fossils can tell us about a dinosaur.
- Eye Scream: How they disable their prey before the kill.
- Failed a Spot Check: The park staff didn't realise the dinosaurs were venomous until they were observed hunting indigenous rodents on the islands, and no one knew they could spit venom until a keeper was nearly blinded. After that incident, park management tried to have the venom glands removed, but couldn't find them despite two rounds of surgery, and management refused to kill one of the creatures to allow an autopsy to be performed.
- Karmic Death: Delivers one to Nedry when he got lost in the park that he deactivated.
- Ominous Owl: While it's not an owl per say, it has a distinct soft hooting cry like an owl. Considering what a Dilophosaurus can do to a person, this is often a dangerous omen.
- Poison Is Corrosive: Their poisonous saliva (which can kill large rodents with a single bite) is also corrosive, able to burn skin and eyes.
- Super Spit: It spits venom and said-spit can reach its target with a distance of 50 feet.
- Beware My Thagomizer: Though she doesn't use it that much.
- Ill Girl: Remember the sick Triceratops? She was a Stegosaurus in the book.
- Sole Survivor: By the end of the novel, only one Stegosaurus had survived. A few hours later, she perishes along with the other dinosaurs from the Costa Rican Air Force's napalm bombings.
- Stock Dinosaurs: A particularly notable case.
- Adapted Out: Spielberg states that the aviary scene was too expensive and complex to put to film. It was later refitted for the third film, though the Cearadactylus were replaced by Pteranodons.
- All Flyers Are Birds: Referred to as such (they aren't actually) and have grasping talons that no real life pterosaur has.
- Death from Above: Played with; they attack Grant and the kids, but it's entirely for naturalistic reasons (they're territorial).
- Giant Flyer: As pterosaurs, this is to be expected. Especially since the aviary's frame is big enough for normal birds to fly out.
- Hair-Trigger Temper: They're viciously territorial, which is the reason the little hotel that was meant to be built in the aviary had to be cancelled.
- Kidnapping Bird of Prey: Subverted. One of them attempts to do this to Lex, but she can't because Lex is too heavy for her to lift.
- No Name Given: An odd variant. The Park's various technical and promotional lists never refer to them by their species name, instead calling them "pterosaurs" and "pterodactyls". Their species is acknowledged by both Grant and Arnold, however. This might be due to the fact that they're a Seldom-Seen Species and the Park management decided that people would be more familiar with the term "pterodactyl".
- Ptero Soarer: Of the "airborne terror" variety. They're also erroneously referred to as "dinosaurs" and "birds".
- Seldom-Seen Species: And seeing as they never made it into the movies (being replaced by their more famous cousins, the Pteranodons), they'll probably always stay seldom seen.
