[[folder: Gideon]]
A large male stegosaurus. Rescued alongside two other adult male stegosaurus, plus a larger herd of females and younglings, he is also amongst the very first animals rescued and brought back to the park.

* BadassInCharge: Is the leader of his small group of male stegosaurus, and he is not an opponent to be taken lightly in the event of a battle.
* BewareMyStingerTail: As expected of a stegosaurus, his tail comes with the famed thagomizer spikes.
* BigEater: A large amount of plants he and his kind like to eat are successfully used as bait to get him and the other stegosaurus through the portal, and he is shown once again taking part in a meal during his next appearance in ''All Creatures Great and Small''.
* CanonForeigner: While his species was rescued in ''Prehistoric Earth'', there is no explicit evidence that he himself was amongst the group rescued in the former fanfic.
* InterspeciesFriendship: Has shown signs of potentially someday forming a bond with Drew.
* LargeAndInCharge: Appears to be the accepted leader of the small group of adult male bachelor stegosaurus, and is naturally the usual size for the species.
* ReasonableAuthorityFigure: He is well aware of the authority of the larger stegosaurus herd's matriarch, and is perfectly happy to respect her group's boundaries as long as she does the same for his own.
* StealthyColossus: Manages in ''Glorious at the Top'' to avoid detection by Drew until he's close enough to him to allow the enclosure's wall to be the only thing preventing him from coming into position literally right next to him.
* TailSlap: This, combined with BewareMyStingerTail, is his most common means of defense.
* ToughArmoredDinosaur: He is a stegosaurus after all.

[[folder:Arlo]]
A lone male juvenile apatosaurus. First found trapped in quicksand, heavily wounded on his back from an attack by a Saurophaganax, and at risk of getting hunted and eaten by a pack of Ceratosaurus as well as a combined float of Amphicotylus and Diplosaurus. He is subsequently rescued and sent to the park, where he receives proper medical care and later shows signs of bonding with Linda.
----

[[folder:Broken Jaw]]
A male allosaurus europaeus who was first rescued alongside his mate and two hatchlings during ''All Creatures Great and Small''. Came to the park with a previously broken jaw that hadn't set properly after healing, which was subsequently given proper treatment and 'healing' by the park vets.

[[folder: Gideon]]
A large male stegosaurus. Rescued alongside two other adult male stegosaurus, plus a larger herd of females and younglings, he is also amongst the very first animals rescued and brought back to the park.

[[folder:Newter]]
One of the adult scapherpeton rescued from Hell Creek for the park.

* AmphibianAssault: Beats up Spiny the dimetrodon when he accidentally lands on him over the course of one of his ill-fated attempts at hunting Larry.
* AmphibianAtLarge: He is at least three feet long, which makes him noticeably longer and bigger than most modern day amphibians.
* BigEater: Is noted by Aaron to love to eat sizable portions of the food that he and his kind receive during their feeding times at the park.

* InterspeciesFriendship: Has formed a bond with his primary keeper Aaron.
* PoisonousPerson: Subtly implied in that, while there is no guaranteed explicit information of him being poisonous like some modern species of frog and salamander, his keepers nonetheless wear protective gloves on their hands when handling him and his species, just in case.
* UseYourHead: The first thing he does to beat up Spiny after the young dimetrodon lands on him and incurs his wrath is to ram his head against his chest.

[[folder:Toby]]
One of the axestemys rescued from Hell Creek for the park.

* BigEater: Is always eager to take a bite or two out of both his regular feedings and any extra treats that Carmen likes to give him.

* FasterThanTheyLook: Noticeably manages to travel a sizable distance in between gazes at him from Colette in a very short time despite being a turtle.
* InterspeciesFriendship: Has formed a bond with his primary keeper Carmen.

* BewareMyStingerTail: As expected of a stegosaurus, his tail comes with the famed thagomizer spikes.
* BigEater: A large amount of plants he and his kind like to eat are successfully used as bait to get him and the other stegosaurus through the portal, and he is shown once again taking part in a meal during his next appearance in ''All Creatures Great and Small''.
* CanonForeigner: While his species was rescued in ''Prehistoric Earth'', there is no explicit evidence that he himself was amongst the group rescued in the former fanfic.
* InterspeciesFriendship: Has shown signs of potentially someday forming a bond with Drew.
* LargeAndInCharge: Appears to be the accepted leader of the small group of adult male bachelor stegosaurus, and is naturally the usual size for the species.

* ToughArmoredDinosaur: He is a stegosaurus after all.

[[folder:Arlo]]
A lone male juvenile apatosaurus. First found trapped in quicksand, heavily wounded on his back from an attack by a Saurophaganax, and at risk of getting hunted and eaten by a pack of Ceratosaurus as well as a combined float of Amphicotylus and Diplosaurus. He is subsequently rescued and sent to the park, where he receives proper medical care and later shows signs of bonding with Linda.

* BadassInDistress: With his species' size and strength, he could easily fight off threats if he puts his mind to it/needs to. However, he is first introduced in need of rescue from carnivores as a result of him being both already wounded as well as trapped in quicksand.
* CanonForeigner: Was not explicitly present amongst the representatives of his species that were rescued in ''Prehistoric Earth''.
* CowardlyLion: Despite weighing more than a bull African elephant, he isn't really confrontational and sometimes has to rely on Shorty to stand up for him. However, in ''Hell's Labyrinth'', he took on a saurophaganax to protect Linda, Jack and Collete from it... and ''won''.
* {{Foil}}: To Shorty, the other main Morrison sauropod.
** Physically, Arlo is a long, lightly built diplodocid, who is a solid grey, whilst Shorty is a tall, bulky brachiosaur with red skin with black patches.
** In regards to their personalities, Arlo is a CowardlyLion, whilst Shorty is a BoisterousBruiser.
* GentleGiantSauropod
* InterspeciesFriendship: With Shorty the Brachiosaurus.
* LikeASonToMe: From the way she acts when it comes to him, Linda is heavily implied to view him as this; something that does not escape Collete or Jack's attention (and the former is [[DisapprovingLook heavily implied to not at all approve of]]).
* QuicksandSucks: Is introduced trapped in quicksand.
* SensitiveGuyAndManlyMan: The Sensitive Guy to Shorty's Manly Man.
* ShoutOut: Is named after the protagonist of ''WesternAnimation/TheGoodDinosaur'', and is even of the same species to boot!

[[folder:Gertie]]
The elderly female leader of the park's resident apatosaurus herd.

* AuthorityInNameOnly: A variation. She may be the officially accepted leader of the herd, but most of the heavy lifting is left to the comparatively younger adult male Bron.
* BadassInCharge: While she may have her enforcer Bron do most of the heavy lifting, age has nonetheless done nothing to diminish her ability to be a capable leader of her herd.
* CanonForeigner: Much like Arlo, there is no evidence that she was present amongst her species representatives rescued in ''Prehistoric Earth''.
* GentleGiantSauropod: When she's not rejecting would-be newcomers to the herd that is.
* LargeAndInCharge: Is the leader of the apatosaurus herd, and is of appropriate size for her age and species.
* ShoutOut: Is named after the titular sauropod from ''WesternAnimation/GertieTheDinosaur''.

[[folder:Bron]]
A fully grown adult male apatosaurus amongst the park's resident herd. Acts as Gertie's enforcer.

* ActionDad: According to WordOfGod, he has a son named Littlefoot, just like his namesake.
* BadassInCharge: Is more than capable of fulfilling his position in the herd as Gertie's enforcer.
* CanonForeigner: Never appeared in Prehistoric Earth prior to his appearance in this story.
* GentleGiantSauropod: Around his son Littlefoot and the rest of their herd; but not towards any hopeful newcomers to the herd that Gertie doesn't accept.
* TheLancer: To Gertie.
* LargeAndInCharge: Is of appropriate size for his age and species, and acts as an enforcer for Gertie.
* ReasonableAuthorityFigure: It is revealed in ''Two Sides of One Coin'' that, in the months that have passed since Arlo's initial rejection from receiving membership to the larger apatosaurus herd and subsequent befriending of Shorty and the brachiosaurus herd, he and the other apatosaurus have come to eventually start allowing Arlo to eat and drink alongside them at the very least (complete with Bron himself only letting out annoyed snorts upon catching sight of Arlo instead of angrily bellowing and trying to chase him away like before).
* ShoutOut: Is named after Littlefoot's father in ''WesternAnimation/TheLandBeforeTime'' ([[WordOfGod and he himself may very well have a son amongst the herd named after his namesake's own son]]).

[[folder:Baylene]]
The elderly female leader of the park's resident brachiosaurus herd.

* ActionMom: Still has enough energy in her to personally discipline would-be usurpers in her herd despite her old age, and has a fully grown son named Adin.
* AsskickingEqualsAuthority: Much like [[Literature/WatershipDown the Threarah]], she still has enough energy in her despite her old age to personally discipline any whippersnappers and would-be usurpers in her herd, usually by [[CorporalPunishment smacking them with her tail]], almost as if to say, 'I may be old; but I'm not ''that'' old'.
* BadassInCharge: Is the alpha female of her herd, and still has enough energy in her despite her old age to personally discipline whippersnappers and would-be usurpers in her herd.
* CanonForeigner: Never appeared in Prehistoric Earth.
* CorporalPunishment: Her default tactic for dealing with whippersnappers and would-be usurpers in her herd is to [[TailSlap smack them with her tail]].

* LargeAndInCharge: Of appropriate size for her age and species, and is the leader of her herd.
* NeverMessWithGranny: As old as she is, she's still perfectly capable of personally disciplining any whippersnappers, upstarts, and would-be usurpers in her herd dumb enough to try to challenge or openly defy her.
* ShoutOut: Named after a similarly elderly brachiosaurus from {{WesternAnimation/Dinosaur}}, and utilizes a punishment technique for whippersnappers and would-be usurpers in her herd similar to the one used by [[Literature/WatershipDown the Threarah]] (complete with the seeming justification of her doing this to say 'I may be old; but I'm not ''that'' old').
* TailSlap: As mentioned above, she usually prefers to discipline would-be usurpers and whippersnappers in her herd by smacking them with her tail.

[[folder:Shorty]]
One of the juvenile males amongst the brachiosaurus herd, and an unexpected ally to Arlo [[spoiler: after the latter's rejection for membership amongst the larger apatosaurus herd]].

* BigBrotherInstinct: He becomes rather protective of Arlo.
* BoisterousBruiser: He's always up for a scrap or two.
* CanonForeigner: Was not present in Prehistoric Earth.
* {{Foil}}: To Arlo, the other main Morrison sauropod of their age group.
** Physically, Arlo is a long, lightly built diplodocid, who is a solid grey, whilst Shorty is a tall, bulky brachiosaur with red skin with black patches.
** In regards to their personalities, Arlo is a CowardlyLion, whilst Shorty is a BoisterousBruiser.
* GentleGiantSauropod: A bit of a prankster, but is nonetheless fairly amicable.
* InterspeciesFriendship: Forms one with Arlo the apatosaurus.
* IronicName: Much like his namesake, he's destined to be quite large once he's fully grown (and he's already the exact same size, if not slightly larger, as a fully-grown giraffe despite still being a juvenile).
* SensitiveGuyAndManlyMan: The manly man to Arlo's sensitive guy.
* ShoutOut: Is named after the young brachiosaurus character from ''WesternAnimation/TheLandBeforeTime''.

[[folder:Broken Jaw]]
A male allosaurus europaeus who was first rescued alongside his mate and two hatchlings during ''All Creatures Great and Small''. Came to the park with a previously broken jaw that hadn't set properly after healing, which was subsequently given proper treatment and 'healing' by the park vets.

* AppetiteEqualsHealth: Linda and Yolanda take the fact that he's eating healthily without any trouble several weeks after his jaw correction surgery as a sign that he's still recovering well.
* CanonForeigner: Didn't appear in Prehistoric Earth.
* GoodParents: He and his mate are implied to be this to their son and daughter.
* HandicappedBadass: His jaw was broken and improperly healed when he was first brought back to the park, and he still has a slight underbite after getting his jaw successfully corrected in surgery, and he's still very much a force to be reckoned with.
* HappilyMarried: To his mate.
* MeaningfulName: See above description for why he's named ''Broken Jaw''.
* ShoutOut: Named after another allosaurus with a similar jaw injury in ''Series/DinosaurRevolution''.

[[folder:Nemo]]
A young male nothosaurus that is encountered during ''New Blood''.

* CanonForeigner: Was not present in Prehistoric Earth.
* InterspeciesFriendship: Has formed a small bond with Stavros the Ancient Mariner captain.
* RidiculouslyCuteCritter: His adorable appearance is enough to convince the crew of the Ancient Mariner to agree to Drew, Alice, and Jack's idea to let him stay on board the ship until the mission is finished and its time to go home during ''New Blood''.
* SeaMonster: Averted. He behaves like an ordinary sea animal, and he is also only a youngster at that.
* ShoutOut: Named after [[Literature/TwentyThousandLeaguesUnderTheSea Captain Nemo]].

[[folder:Sid]]
A male megatherium. Rescued alongside his mate Camille during ''Red in Tooth and Claw''.

* AdaptationalNiceGuy: A downplayed example when it comes to his species. In ''Prehistoric Earth'', his species served as a partial KnightOfCerebus over the course of the chapter in which they were rescued. Here, he and the rest of his kind are 100% [[GentleGiant gentle giants]].
* BattleCouple: With his mate Camille. In fact, they are first introduced in the story viciously defending themselves from an adult female [[BearsAreBadNews arctotherium]].
* BearyFriendly: Whilst not truly a bear, he's often compared to one - and he's a GentleGiant.
* BewareTheNiceOnes: Whilst he's a GentleGiant, he still weighs four tons and has seven-inch claws - piss him off at your peril.
* BigEater: Loves to eat. It's reached the point that he'll gladly shake any tree branches he's just finished eating from to see if any more leaves will come down for him to eat. He'll even do this to the branches of the mechanical feeding trees.
* CanonForeigner: While his species was rescued in Prehistoric Earth, he himself was not explicitly confirmed to be amongst the megatherium rescued in the former fanfic.
* CloudCuckooLander: He can be rather goofy and a tad dim at times.
* CrouchingMoronHiddenBadass: Can act rather goofy and dim outside of combat, but as can be attested by one of the rescued adult female arctotherium, he can be a real force to be reckoned with when he's in serious danger.
* GentleGiant: When he's not fighting for his life of course.
* HappilyMarried: Is happily mated to Camille (who just so happened to be rescued alongside him).
* InterspeciesFriendship: Has formed a bond with Linda the head veterinarian.
* MightyGlacier: Almost never moves faster than a slow 'shambling' when ever he actively moves around anywhere. But given just how big he is and the utterly massive claws he has on his 'hands', his slow speed is hardly all that much of an impediment.
* ShoutOut: Twofold. He is named after both the ground sloth character from the ''WesternAnimation/IceAge'' franchise and the titular protagonist from the novel Siddhartha by Creator/HermannHesse. His mate Camille is likewise named somewhat similarly to Siddhartha's sort of love interest Kamala from the same novel.
* SluggishSloths: Ziz-zagged. On the one hand, he can swing his arms very swiftly indeed when in the midst of a battle. But otherwise, he is commonly described as moving in a slow shambling gait.

[[folder:Dermot]]
A male doedicurus. Rescued alongside three others of his kind during ''Red in Tooth and Claw''.

* BewareMyStingerTail: Has a large tail with a spiked mace-like bludgeon at the tip.
* BewareTheNiceOnes: Can be plenty friendly when in a good mood. But regardless, his thick armor and powerful bludgeoned tail are ''not'' for show.
* BruiserWithASoftCenter: Wears a thick armored shell, has [[BewareMyStingerTail a tail with a spiked bludgeon at the tip]], and is about the size of a small Volkswagen, but is also perfectly capable of acting like a happy child playing with toys whenever he gets the chance to play with the exercise balls he and the others of his kind get to use as enrichment.
* CanonForeigner: There is no evidence that he personally was amongst the animals rescued in Prehistoric Earth.
* EpicFlail: What his tail essentially serves as.
* GentleGiant: When in a good mood of course.
* InterspeciesFriendship: While 'friendship' may be pushing things considering the rules of animal care, he has formed a bit of a bond with hoofstock keeper Horace Northup.
* MightyGlacier: Is not the fastest of animals amongst the park's animal repertoire by any means. But with his thick shell and large spiked tail, he hardly needs to be all that fast.
* UncattyResemblance: Big, stocky and tough, but with a soft center, much like Horace.

[[folder:Smokey]]
A single solitary male arctodus. Was first encountered and rescued in ''Oozing From the Pit'' over the course of a territorial battle he fought against Diego the smilodon fatalis.

* BearsAreBadNews: Downplayed. Whilst he's not evil or even malicious, he's still fierce and menacing - and is introduced pummeling Diego near to death. And he becomes even more aggressive than normal while infected with the HatePlague.
* CanonForeigner: Never appeared in Prehistoric Earth.
* EvilIsBigger: Downplayed - whilst he's not evil per se, his enmity with Diego makes him one of the more antagonistic park creatures... and he's 11 feet tall on his hind legs.
* {{Foil}}: To Dag. Both are the comparatively more antagonistic rivals to a Pleistocene La Brea predator (Diego for Smokey and Nero for Dag). But while Smokey is a big, strong, and tough bear that would be more than capable of killing Diego (and, indeed, very nearly did), Dag is a thin and comparatively weak coyote that would have no chance in a fair fight against Nero the dire wolf.
* TheHermit: He's not exactly the most social of bears, and seems to heavily prefer living alone in the arctodus enclosure instead of hanging around the larger sleuth of his kind.
* MightyRoar: He is a bear after all.
* NoSell: Easily shakes off the minor bite wounds to his shoulder that Diego inflicts upon him during their duel in ''Oozing from the Pit''.
* TheRival: To Diego the smilodon fatalis.
* ShoutOut: He is named after the famous forest fire prevention mascot.

[[folder:Diego]]
A male smilodon fatalis. Was first encountered and rescued in ''Oozing From the Pit'' after a vicious territory battle he fought against Smokey the arctodus. Now lives at the park alongside a female named Shira.

* AdaptationalEarlyAppearance: Was first rescued in ''Prehistoric Earth'' in the penultimate mission to occur before the two part 'series finale'. Here, he's rescued in the 5th episode of the 1st 'season'.
* AndroclesLion: Was narrowly prevented from getting killed by [[BearsAreBadNews Smokey the arctodus]] by a timely intervention from Leon, who subsequently spent a decent amount of time personally watching over him and taking care of him during both his recovery period and his subsequent time as a healthy resident of the park. Much later, during the Shutdown, Diego manages to save Leon from getting mauled by Smokey when the bear ambushees him
* AscendedExtra: Only appeared for a few brief scenes at the park after his rescue in ''Prehistoric Earth''. Here, he plays a prominent role in the story several episodes after his initial rescue and even forms a bond with Leon.
* BabiesEverAfter: Has three cubs with Shira.
* BadassInDistress: Is a capable fighter, but just happened by sheer bad luck to be up against a considerably more badass opponent at the moment in which he was first introduced in the story.
* BirdsOfAFeather: Implied to have bonded very well with Shira over the course of their time together at the vets after their respective rescues.
* CurbStompBattle: Is ultimately soundly defeated by Smokey in their duel in ''Oozing From the Pit'', and would have been killed [[BigDamnHeroes if not for a timely intervention from Leon]].
* CurbStompCushion: That being said though, he ''was'' able to put up quite a fight against Smokey even after receiving multiple wounds while barely even giving so much as a scratch to the bear.
* {{Determinator}}: As evidenced by how he was behaving over the course of his battle against Smokey, he clearly does not give up easily.
* HappilyMarried: Is revealed in ''The D-Bags'' to now be happily mated with Shira.
* ICanStillFight: Still refused to give up in his first battle against Smokey even after receiving multiple serious wounds. And he was still working to get himself back up onto his feet even after getting sent flying and engaging in a painful impact against the side of a tree after being sent flying towards it as well as an equally painful landing, and probably ''would have gotten back up all the way'' if Smokey hadn't been fast enough to charge on over in time to smack him back down before he'd finished getting back on his feet.
* InterspeciesFriendship: Forms a bond with Leon.
* MadeOfIron: He was still actively putting up a serious fight against Smokey during their first battle against each other even after receiving multiple serious scratches, bites, bruises, and other wounds. And as mentioned in ICanStillFight above, he was still able to make a conscious attempt to get back on his feet even after getting sent flying right up against the side of a large tree.
* MightyRoar: He is a smilodon, so he naturally engages in this during his duels against Smokey, and occasionally even during times of peace.
* PantheraAwesome: Again, he is a smilodon.
* PapaWolf: Proves to be viciously protective of his cubs three weeks after they're born by fighting his second ever duel against Smokey immediately after he catches the latter dangerously close to his and Shira's paddock over the course of the storm in ''Hell's Labyrinth''.
* PunchedAcrossTheRoom: Sent flying a small distance, and slamming against the side of a large tree, by a swing of one of Smokey's paws.
* TheRival: To Smokey the arctodus.
* ShoutOut: Is named after the famous saber-toothed tiger from ''WesternAnimation/IceAge''.
* UncattyResemblance: He and Leon are both very guarded and wary when around people or animals they don't know all that well and can give off antisocial vibes when on their own, but immediately let down their walls when around those they really care about.

[[folder:Shira]]
A female smilodon fatalis. Was first rescued alongside multiple other animals in ''Oozing From the Pit'' from sinking to her doom in the La Brea Tar Pits.

* AdaptationalEarlyAppearance: Was rescued in the penultimate rescue mission before the 'series finale' of ''Prehistoric Earth''. In this story, she is rescued in the 5th episode of the 1st 'season'.
* AscendedExtra: Only underwent a few minor appearances at the park after her rescue in Prehistoric Earth. Here, she plays a much more prominent role at the park alongside Diego after her rescue.
* BabiesEverAfter: Has three cubs with Diego.
* BadassInDistress: Is a capable fighter and hunter, but just happened to be unlucky enough to go wandering into the La Brea Tar Pits.
* BirdsOfAFeather: Is implied to have bonded very well with Diego over the course of their time together at the vets after their respective rescues. They even share an exhibit together.
* GoodParents: Is a very doting and caring mother to her and Diego's cubs.
* HappilyMarried: Is revealed in ''The D-Bags'' to be happily mated with Diego (and even carrying his cubs).
* MightyRoar: Lets off one of these to announce her turf at the end of ''Oozing From the Pit''.
* QuicksandSucks: Was trapped in the La Brea Tar Pits at the time of her rescue.
* PantheraAwesome: She is a smilodon after all.
* ShoutOut: Is named after Diego's love interest in ''WesternAnimation/IceAgeContinentalDrift''.

[[folder:Nero]]
Alpha male of a dire wolf pack rescued in ''Oozing From the Pit''. Was one of the lucky victims rescued from sinking in the La Brea Tar Pits.

* ActionDad: An implied case in that the four members of his pack that are still youngsters might very well be his own pups.
* BadassInCharge: Is very much capable of holding his own as the leader of his pack.
* BadassInDistress: As capable of a leader as he is for his pack, he was just as helpless as they were in the La Brea Tar Pits.
* CanonForeigner: Neither he himself, nor his species, ever appeared in Prehistoric Earth.
* HappilyMarried: To his mate Lara.
* InterspeciesFriendship: Has formed a fairly close bond with Colette.
* NamedAfterSomebodyFamous: Named after the famed Roman emperor.
* NobleWolf: Acts very honorably as the alpha of his pack. Won't stop him from occasionally acting [[SavageWolves rather vicious]] though...
* PapaWolf: Literally.
* QuicksandSucks: Was trapped in the La Brea Tar Pits alongside his entire pack.
* TheRival: Views Dag the alpha male Pleistocene coyote as this. And it's very much a mutual feeling on Dag's end.
* SavageWolves: Will gladly show off his more fearsome side to those who get on his bad side; [[TheRival especially]] [[AnimalJingoism against]] [[ThoseWilyCoyotes Dag the Pleistocene coyote]].
* UncattyResemblance: Much like Colette, he can be very tough, firm, and seemingly aloof, but cares strongly for and is viciously protective of those he has bonded closely with.
* YellowEyesOfSneakiness: He is a wolf after all.

[[folder:Eshe]]
A lone female American Cheetah rescued by Alice in ''Oozing from the Pit''.

* BadassInDistress: She may be a fairly decent hunter, but she was still able to get seriously wounded by ''something'' prior to Alice first catching sight of her, and was subsequently left too weak and helpless to defend herself from [[CirclingVultures a hungry pair of teratornis]] that decided to try to finish the job and eat her.
* CanonForeigner: Neither she, nor her species, ever appeared in Prehistoric Earth.
* FragileSpeedster: Can run pretty fast, but was clearly not durable enough to avoid getting seriously wounded by whatever creature gave her the serious scratch wound across her side that she has when Alice first encounters her.
* InterspeciesFriendship: Has formed a decently close bond with Alice.
* PantheraAwesome: She is an American Cheetah.

[[folder:Dag]]
Alpha male of a pack of Pleistocene coyotes rescued in ''Oozing From the Pit''. Much like Nero and the other dire wolves, he and his pack were amongst the lucky victims rescued from the La Brea Tar Pits.

* BoisterousWeakling: He spends most of his scenes in "Hell's Labyrinth" picking fights he can't win - and humiliatingly losing.
* BullyingADragon: His frequent antagonism of Nero counts, since Nero could kill him easily, and [[spoiler:kicks his ass during the Shutdown]].
* ButtMonkey: "Hell's Labyrinth" does not represent his finest hour - in quick succession, he gets sprayed in the face by a fire extinguisher, gets his ass kicked by Nero, before fleeing, attempts to raid the dromaeosaurus nest, before being curbstomped by Duke and, finally, having Nero snap at his tail as he retreats.
* CanonForeigner: Neither he, nor his species, were present in Prehistoric Earth.
* DirtyCoward: A strange combination of this and FearlessFool. Whilst he's perfectly happy to [[BullyingADragon pick fights he can't win]] he's very quick to run when he realizes he's going to lose.
* FearlessFool: A strange combination of this and DirtyCoward - whilst he's perfectly happy to go round picking fights he can't win, he's very quick to run when he ends up humiliatingly losing.
* {{Foil}}: To Smokey. Both are the comparatively more antagonistic rivals to a Pleistocene La Brea predator (Diego for Smokey and Nero for Dag). But while Smokey is a big, strong, and tough bear that would be more than capable of killing Diego (and, indeed, very nearly did), Dag is a thin and comparatively weak coyote that would have no chance in a fair fight against Nero the dire wolf.
* OhCrap: His eyes noticeably widen at one point as if in horror while temporarily pinned to the Hell Creek forest building floor by Nero over the course of ''Hell's Labyrinth''.
* QuicksandSucks: Was trapped in the La Brea Tar Pits alongside his entire pack.
* TheRival: To Nero [[AnimalJingoism the dire wolf]].
* ShoutOut: Is named after the BigBad from ''WesternAnimation/{{Barnyard}}''.
* ThoseWilyCoyotes: Averted in his debut episode, as he was too busy being at the mercy of a tar pit at the time. But once he's safe in his new home at the park though, he shows heavy signs of this in his rivalry against [[SavageWolves Nero]].
* YellowEyesOfSneakiness: He is a coyote after all.

[[folder:Rocco]]
One of two teratornis rescued over the course of ''Oozing From the Pit''. Is first introduced alongside his mate Laverne attempting to straight up kill an already seriously wounded Eshe the American cheetah so as to not have to wait until she dies naturally before eating her and proves rather difficult to work with even after he's been sent to the present and placed amongst the park's animal repertoire.

* AnimalsNotToScale: He and Laverne are portrayed as far larger than their species was in real life (only slightly bigger than an Andean condor) - closer to the size of ''Aiolornis''. The author has admitted that this was for RuleOfCool.
* BrutalBirdOfPrey: Whilst not evil per se, he is very aggressive and pugnacious.
* CanonForeigner: Neither he, nor his mate Laverne (or even their species for that matter), ever appeared in ''Prehistoric Earth''.
* CirclingVultures: He and Laverne are first introduced descending down from the sky after having flown in circles above the severely wounded Eshe.
* EscapedAnimalRampage: Downplayed in that he doesn't really cause all that much damage when he temporarily escapes his enclosure in ''Dogfight''. Nonetheless, he does prove rather difficult to detain over the course of the park's subsequent efforts at recapturing him.
* FeatheredFiend: He and Laverne are very aggressive and unpleasant to work with even before they get rescued and sent to the park from out of their home time period.
* HappilyMarried: For all his faults, he seems to at least have a healthy relationship with his mate Laverne.
* VileVulture: Whilst not evil, he's rather aggressive and pugnacious and plays an antagonistic role in ''Dogfight!'' and the Shutdown.
* YellowEyesOfSneakiness: Comes with being a vulture, and rather appropriate when considering his [[BrutalBirdOfPrey aggressive]] [[VileVulture nature]].

[[folder:Duke]]
Alpha male of a dromaeosaurus pack rescued in ''Return of the King''. First met by Jack alongside Kaa the dinilysia while hiding in a log from a hungry family of t-rex.

* ActionDad: It is implied that four of the youngsters in his pack are his own hatchlings, and he is very much a capable leader of his pack, especially when it comes to action.
* CanonForeigner: Never appeared in Prehistoric Earth. And his species wasn't even rescued in the former fanfic either.
* CompositeCharacter: He has elements of Red (dromaeosaur who forms a close bond with Jack) and the allosaur squad (dinosaur trained by major character for security purposes).
* EnemyMine: He, Kaa, and Jack show absolutely no signs of natural enmity to show between them while they're mutually hiding in a log in fear of a hungry family of t-rex.
* FeatheredFiend: To his prey.
* HappilyMarried: Can be reasonably implied to be the case with his mate Cassie.
* InterspeciesFriendship: Has formed a pretty strong bond with Jack.
* ItCanThink: Is at least smart enough to both seemingly regret leaving Jack and Kaa in the log when he takes the opportunity to escape and seemingly recognize Jack when they encounter each other again while Duke is alongside his pack.
* MomentKiller: Lets out a low throaty squawk of amusement while watching a moment of ShipTease unfold between Colette and Jack during ''Feather and Scale'', which embarrasses the two enough to end their meeting and get back to work. And he does it again in ''Alien Empire''.
* RaptorAttack: Averted. He and his pack are portrayed exactly as up to date with real paleontology as possible.

[[folder:Kaa]]
A dinilysia first encountered by Jack alongside Duke while she is hiding in a log from a hungry family of t-rex in ''Return of the King''.

* AdaptationalEarlyAppearance: Was first rescued in one of the last missions of 'phase 2' in ''Prehistoric Earth''. Here, she is rescued during the 'mid-season finale' of phase 1.
* AscendedExtra: Only appeared in two minor scenes in ''Prehistoric Earth''. Here, she has much more screentime and more time is devoted to her bond with Jack.
* EnemyMine: She, Duke, and Jack show no sign of natural enmity to show between them while they're mutually hiding in a log in fear of a hungry family of t-rex.
* InterspeciesFriendship: Has formed a close bond with Jack.
* MoralityPet: Whilst Jack isn't a bad person per se, Kaa certainly brings out his better side.
* PlatonicLifePartners: An interspecies example with Jack.
* ShoutOut: Named after the iconic snake character from the various incarnations of ''Literature/TheJungleBook''.
* SnakesAreSinister: Very much averted - she's one of the friendlier park creatures overall.
* UndyingLoyalty: To Jack. Even when cornered by a saurophaganax, she refuses to leave him.

[[folder:Cirrus]]
A quetzalcoatlus found heavily wounded in the Cretaceous before being successfully rescued and given proper medical treatment at the park in ''Return of the King''.

* AdaptationalEarlyAppearance: His counterpart in ''Prehistoric Earth'' was first encountered and rescued in around the middle of 'season 2'. In this story, on the other hand, he is rescued during the 'mid-season finale' of 'season 1'.
* AdaptationRelationshipOverhaul: His counterpart in ''Fanfic/PrehistoricEarth'' formed a close bond with Linda and largely wasn't seen to interact all that much (if at all) with Adrian. Here? Adrian is the one he shows signs of forming a close bond with while Linda has only appeared to interact with him about as much as was necessary over the course of his medical care following his rescue.
* AdaptationalSpeciesChange: Unlike his counterpart in ''Fanfic/PrehistoricEarth'', he is a quetzalcoatlus instead of an ornithocheirus.
* AgeLift: Is stated in ''Prehistoric Park: Extras'' to be an adolescent as opposed to the elderly male his counterpart in Prehistoric Earth was.
* AlwaysABiggerFish: To [[VileVulture Rocco the teratornis]]. [[SummonBiggerFish A fact that is immediately exploited]] when Rocco ends up successfully preventing the trained dromaeosaurus pack from successfully getting him captured and led back to his aviary exhibit during his escape in ''Dogfight'' by flying out of their reach.
* BadassInDistress: He's big enough to logically be able to put up a good fight, but is introduced in a state of severe injury and at the risk of dying.
* BigDamnHeroes: Shows up just in time to defend Adrian, Leon, Cass, Horace, and Mohinder from the HatePlague infected [[RaptorAttack pectinodon pack]] over the course of ''Hell's Labyrinth''.
* GiantFlyer: He's as tall as Adrian at the shoulder and he can fly.
* HappilyMarried: Is now happily mated with Nimbus.
* InterspeciesFriendship: Has formed a bond with Adrian.
* PteroSoarer: Averted. He's furry, quadrupedal and picks things up with his beak. He's also accurately depicted as a competent terrestrial walker, much like his species was in real life.
* TheRival: To fellow adolescent male quetzalcoatlus Zephyr. The feeling is mutual. [[spoiler: Until the latter is finally defeated by him in combat in ''The Oddities'' that is.]]
* UndyingLoyalty: To Adrian.
* UncattyResemblance: Somewhat aloof and reserved, but with a softer side, much like Adrian.

[[folder:Rexy]]
An adult female t-rex amongst an entire family rescued in ''Return of the King''.

* ActionMom: She is a mother of two, and still quite capable of kicking ass and taking names.
* CanonForeigner: Never appeared in Prehistoric Earth.
* FeatheredFiend: To her prey.
* GoodParents: Alongside her mate Tyrannor, she is very much a good mother to her son Terrence and daughter Matilda.
* HappilyMarried: To Tyrannor.
* KingOfTheDinosaurs: Proves TheDreaded alongside her family to the combined herd of local herbivorous dinosaurs in their mutual home time period in Hell Creek, and acts suitably ferocious over the course of hunting and later starts showing off her gentler side while she and her family are quietly feasting together alone (presence of the rescue team notwithstanding) on a freshly killed ornithomimus before eventually settling into a balanced mixture of both common portrayals of her species over the course of her time living at the park.
* KnightOfCerebus: Serves as this alongside the rest of her family when actively on the hunt in the Cretaceous Period.
* LightningBruiser: As massive as she is, she can move very fast when she needs to.
* MightyRoar: Technically [[ShownTheirWork more of a mighty bellow]], but the spirit of this trope is still present.
* ShoutOut: Is named after the iconic adult female t-rex from ''Film/JurassicPark'' (and, if you split hairs, after the skeletal male t-rex from ''Film/NightAtTheMuseum'').
* SparedByTheAdaptation: Her counterpart in the original Prehistoric Park series was killed by a rival adult male seconds before the infamous KT event meteor struck the earth. Here she is successfully rescued alongside her mate and offspring.

[[folder:Tyrannor]]
An adult male t-rex amongst an entire family rescued in ''Return of the King'', and Rexy's mate.

* ActionDad: Father of two, and more than capable of throwing his weight around.
* CanonForeigner: Never appeared in Prehistoric Earth.
* FeatheredFiend: To his prey.
* GoodParents: Alongside his mate Rexy, he is a very caring father to Terrence and Matilda.
* HappilyMarried: To Rexy.
* KingOfTheDinosaurs: Proves TheDreaded alongside his family to the combined herd of local herbivorous dinosaurs in their mutual home time period in Hell Creek, and acts suitably ferocious over the course of hunting and later starts showing off his gentler side while he and his family are quietly feasting together alone (presence of the rescue team notwithstanding) on a freshly killed ornithomimus before eventually settling into a balanced mixture of both common portrayals of his species over the course of his time living at the park.
* KnightOfCerebus: Serves as this alongside the rest of his family while actively on the hunt in the Cretaceous Period.
* LightningBruiser: Much like Rexy, he can move deceptively fast for a creature of his size and bulk.
* MightyRoar: Just like with Rexy, the spirit of this trope is present in the bellow he makes.
* ShoutOut: Is named after the main antagonist from ''WesternAnimation/DinkTheLittleDinosaur''.

[[folder:Terrence]]
A juvenile male t-rex rescued in ''Return of the King'', and Rexy and Tyrannor's son.

* AscendedExtra: Plays a major role in this story after having previously been adapted out of Prehistoric Earth.
* FeatheredFiend: To his prey.
* InterspeciesFriendship: Has started to bond with Drew and an adolescent male majungsaurus his age.
* KingOfTheDinosaurs: Proves TheDreaded alongside his family to the combined herd of local herbivorous dinosaurs in their mutual home time period in Hell Creek, and acts suitably ferocious over the course of hunting and later starts showing off his gentler side while he and his family are quietly feasting together alone (presence of the rescue team notwithstanding) on a freshly killed ornithomimus before eventually starting to showcase far more aspects of the noble portrayal of his species over the course of his time living at the park in contrast to his more fearsome sister [[BigSisterBully Matilda]].
* KnightOfCerebus: Serves as this alongside the rest of his family when actively hunting in the Cretaceous Period.
* MythologyGag: Named after one of the young t-rex rescued in the original ''Series/PrehistoricPark'' series.

[[folder:Matilda]]
A juvenile female t-rex rescued in ''Return of the King'', and Terrence's sister.

* AscendedExtra: Plays a major role in this story after having previously been adapted out of Prehistoric Earth.
* BigSisterBully: Becomes this to Terrence over the course of her puberty.

* GreenAndMean: Has sparse dark green feathers on her body and is one of the more antagonistic members of her family, [[BigSisterBully particularly to her brother Terrence]].
* TheHeavy: Out of all the escaped carnivores in ''Hell's Labyrinth'', she ends up arguably causing the most trouble over the course of the park's efforts at recapturing her.
* KingOfTheDinosaurs: Proves TheDreaded alongside her family to the combined herd of local herbivorous dinosaurs in their mutual home time period in Hell Creek, and acts suitably ferocious over the course of hunting and later starts showing off her gentler side while she and her family are quietly feasting together alone (presence of the rescue team notwithstanding) on a freshly killed ornithomimus before eventually starting to showcase far more aspects of the fearsome portrayal of her species over the course of her time living at the park in contrast to her more noble and majestic brother Terrence.
* KnightOfCerebus: Serves as this alongside the rest of her family when actively hunting in the Cretaceous Period [[spoiler: and also while under the influence of the HatePlague and outside of her paddock in ''Hell's Labyrinth'']].
* MightyRoar: Lets out a sizable number of these while infected with the HatePlague over the course of ''Hell's Labyrinth''.
* MythologyGag: Named after one of the young t-rex rescued in the original ''Series/PrehistoricPark'' series.
* RoarBeforeBeating: Noticeably hisses at the sight of Jack in the same clearing as her and her family before she goes charging after him. And she also goes so far as to outright ''roar'' immediately prior to her hunting attempts and battles she engages in over the course of ''Hell's Labyrinth''.

[[folder:Felix]]
An adult male arthropleura rescued in ''Alien Empire''. First introduced when he is accidentally startled by Leon stepping a little ''too close'' to him for comfort, and is subsequently sent through the portal once he's calmed down.

* AdaptationalNameChange: He was called Incursio in Prehistoric Earth.
* AscendedExtra: Plays a much larger role later in the story (including forming a bond with ''Nikolai'') compared to his barely present at all Prehistoric Earth counterpart Incursio.
* BigCreepyCrawlies: Subverted. His large size arguably robs him of creep factor instead of enhancing it.
* BigDamnHeroes: Appears to scare three pectinodon off when they'd cornered Jack and Duke in ''Hell's Labyrinth''.
* BigEater: An implied case judging by just how eager he appears to be to feast on plant matter in a large number of the scenes he's appeared in so far.
* CreepyCentipedes: See BigCreepyCrawlies above. Also, he's a milipede, not a centipede.
* GentleGiant: Despite giving the rescue team a good startling in his first scene(in all fairness, they startled him first), he's rather placid.
* InterspeciesFriendship: Has shown signs of forming a bond with Nikolai.
* MoralityPet: Arguably seeming to be set up as this for Nikolai.
* OppositesThemeNaming: Is named after the Latin word for 'luck', whereas the female arthropleura (and likely his future mate) is named Melancholia (which is arguably one of the furthest feelings from lucky one can feel).

[[folder:Selqet]]
A female pulmonoscorpius that is first captured in ''Alien Empire'' after being seen crawling on a sleeping Drew's back.

* AscendedExtra: Appears far more often in this story (and even bonds with one of the park staff members) compared to her comparative Prehistoric Earth counterpart Murasame.
* BewareMyStingerTail: She is a scorpion after all.
* BigCreepyCrawlies: While not ''Film/TheBlackScorpion'' level big, she is amongst one of the noticeably largest prehistoric species of scorpion, and her introductory scene is played for suspense.
* CanonForeigner: Her species was rescued in Prehistoric Earth, but the closest thing she had to a counterpart was a male named Murasame who never appeared in the story again after his debut episode.
* InterspeciesFriendship: With Bethany the veterinarian.
* LittleMissBadass: Downplayed in that she doesn't necessarily get the chance to do any serious damage to anyone, the seemingly quite angry response she gives after getting trapped in a bug cage indicates that she can at least be a bit of a spitfire.
* PowerPincers: Comes with being a scorpion.
* RedAndBlackAndEvilAllOver: Not evil, but certainly played for suspense in her introductory scene, and she has a black exoskeleton with red stripes on her claws and a red tipped stinger on her tail.
* ReligiousAndMythologicalThemeNaming: Is named after the Egyptian scorpion goddess.
* ScaryScorpions: While not necessarily portrayed as any more dangerous than any real life modern scorpion, her introduction scene is noticeably played for suspense.

[[folder:Neith]]
A representative of 'megalorachne', a newly discovered prehistoric species of spider. Also the first of her kind to be encountered by the rescue team (and by humanity in general) and subsequently rescued for the park.

* AdaptationalNameChange: Was named Pumpkin in Prehistoric Earth.
* AscendedExtra: Her Prehistoric Earth counterpart Pumpkin only appeared in her debut chapter in that story without ever appearing again. Here, she makes several other minor background appearances in both a main story chapter and a chapter in the spinoff ''Extras'' after her debut, and even starts forming a bond with one of the vets.
* BigCreepyCrawlies: Is certainly unnerving ([[WhyDidItHaveToBeSnakes at least to Leon]]), and is about the size of Leon's head.
* CrashIntoHello: Played with. While the rescue team (and the readers) don't get a proper full view of her or similar proper introduction until after she's already landed on the ground, she only lands there after getting shaken off from her initially landing on Leon's head.
* DeathFromAbove: Subjects a luckless hylonomus to this fate after lunging out of her burrow when it causes the webbing surrounding the entrance to vibrate while its running past said burrow.
* GiantSpider: As described in BigCreepyCrawlies above, she is at least the size of Leon's head.
* InterspeciesFriendship: With Bethany the veterinarian.
* RedAndBlackAndEvilAllOver: Not evil, per se, but she is described in seemingly unnerving fashion, and has a black body with scarlet red pincers.
* ReligiousAndMythologicalThemeNaming: Is named after the Egyptian goddess of the hunt.
* SpidersAreScary: [[WhyDidItHaveToBeSnakes Particularly to Leon]].

* StockDinosaurs: He is a stegosaurus.

* StockDinosaurs: He is an apatosaurus.

* StockDinosaurs: She is an apatosaurus.

* StockDinosaurs: He is an apatosaurus.

* StockDinosaurs: Specifically, a brachiosaurus.

* StockDinosaurs: He is a brachiosaurus.

* StockDinosaurs: While not of the most commonly known species, he is nonetheless an allosaurus.

* StockDinosaurs: He is a megatherium, one of the most commonly known 'ice age' mammals.

* StockDinosaurs: Is a doedicurus, a very commonly known species of glyptodont.

* StockDinosaurs: He is an arctodus.

* StockDinosaurs: He is a smilodon, the infamous 'saber-toothed tiger'.

* StockDinosaurs: Again, she is a smilodon.

* StockDinosaurs: He is a dire wolf, one of the 'ice age's' most commonly known mammal carnivores.

* StockDinosaurs: Downplayed. Whilst his genus is one of the stock pterosaurs, he is a member of the lesser-known smaller species, as opposed to the better known Quetzalcoatlus northropi.

* StockDinosaurs: THE stock dinosaur in fact.

* StockDinosaurs: He is a t-rex. Enough said.

* StockDinosaurs: He's a UsefulNotes/TyrannosaurusRex, need any more be said?

* StockDinosaurs: As already established, she is a t-rex.

* StockDinosaurs: He's a dimetrodon, one of the most commonly known synapsids.

* StockDinosaurs: He is a pachycephalosaurus.

* StockDinosaurs: A ''Dimetrodon''.

* StockDinosaurs: He is a triceratops.

* StockDinosaurs: He is an argentavis, a widely known giant prehistoric vulture species.

* StockDinosaurs: She is a pterygotus, one of the of most iconic eurypterids in media.

* StockDinosaurs: He's a cave bear - one of the "stock" Ice Age mammals.

* StockDinosaurs: She's a woolly mammoth - ''the'' [[MammothsMeanIceAge iconic animal of the Ice Age]].

* StockDinosaurs: He is a megaloceros, a fairly well known prehistoric deer.

* StockDinosaurs: Again, he is a cave lion, a fairly easily recognized animal from the Ice Age.

* StockDinosaurs: Again, she is a cave lioness, an easily recognized animal from the Ice Age.

* TurtlePower: Is an axestemys, a species of cretaceous turtle.

* TurtlePower: Is a basilemys, a species of cretaceous turtle.

* SeldomSeenSpecies: Nothosaurus aren't exactly the most prominent prehistoric ocean animals featured in media.

* SeldomSeenSpecies: When was the last time an American Cheetah was prominently featured in mainstream media?

* SeldomSeenSpecies: The Pleistocene coyote is nowhere near as widely known compared to the dire wolf.

* SeldomSeenSpecies: Compared to some of the more iconic Cenozoic birds of prey, teratornis isn't quite as famously known.

* SeldomSeenSpecies: He is a dromaeosaurus, which is not quite as instantly recognizable as others in the family such as velociraptor and troodon.

* SeldomSeenSpecies: Dinilysia haven't exactly been mainstays in most dinosaur media.

* SeldomSeenSpecies: Proterogyrinus is not exactly a mainstay in most media.

* SeldomSeenSpecies: He is a scapherpeton, which does not often come to mind when people think of prehistoric animals prominently featured in most media.

* SeldomSeenSpecies: Axestemys are not amongst the most commonly known prehistoric reptiles.

* SeldomSeenSpecies: Basilemys are not amongst the most commonly known prehistoric reptiles.

* SeldomSeenSpecies: Petrolacosaurus is definitely not one of the first animals that comes to mind when one thinks of popular animals from the Paleozoic Era.

* SeldomSeenSpecies: Compared to the likes of velociraptor, saurornitholestes are not the most famously known of 'raptor' dinosaurs.

* SeldomSeenSpecies: Palaeosaniwa are not exactly the most commonly featured in media.

* SeldomSeenSpecies: Denversaurus are one of the lesser known species of ankylosaur.

* SeldomSeenSpecies: Cryolophosaurus is hardly the most commonly featured theropod dinosaur in most media.

* AndroclesLion: Was narrowly prevented from getting killed by [[BearsAreBadNews Smokey the arctodus]] by a timely intervention from Leon, who subsequently spent a decent amount of time personally watching over him and taking care of him during both his recovery period and his subsequent time as a healthy resident of the park. Much later, during the shutdown in the 'season 1 finale', Diego manages to incidentally save Leon from getting mauled by Smokey when he chooses to engage in a rematch with the bear not too long after Smokey incidentally reveals himself to be worrisomely close to where Diego's mate Shira and their three relatively recently born cubs are lying asleep in the smilodon fatalis paddock.

* AndroclesLion: Leon plays a major role in getting him calmed down and in ideal condition for getting led through the portal after a wary first meeting. And from there, he spends enough time with Simba over the course of his subsequent recovery time from his surgery and getting settled into his new home at the park for the two of them to develop a fairly close companionable bond together.

* AscendedExtra: Only appeared for a few brief scenes at the park after his rescue in Prehistoric Earth. Here, he plays a prominent role in the story several episodes after his initial rescue and even forms a bond with Leon.

* HandicappedBadass: Is blind in one eye.

* AdaptationDyeJob: His technical counterpart in ''Prehistoric Earth'' had pale snowy white hair and can be inferred to have had a similarly colored sparse mane. Here, in a visual homage to his namesake, his fur is a tawny gold and his mane is a fiery auburn.

* AdaptationalHeroism: Downplayed. The closest thing he had to a counterpart in ''Prehistoric Earth'' was not by any means a true 'villain', but said counterpart was introduced hunting after a woolly mammoth calf alongside Nala's counterpart, proved ''very'' antagonistic and damn near killed Leon in ''Full Fathom Five''. Here, he is introduced wounded and afraid, but ultimately able to get calmed down by Leon and eventually even ends up forming a companionable bond with the boy.

* AscendedExtra: Played with. While the closest thing he had to a counterpart in ''Fanfic/PrehistoricEarth'' was never explicitly referred to as Simba, he ultimately gets set up to have a much larger role to play in this story than his technical counterpart in ''Prehistoric Earth'' did by virtue of ending up forming a bond with Leon similar to the kind Leon has with Diego.

* AdaptationalVillainy: Downplayed in that she's not truly a villain. However, while her counterpart in ''Prehistoric Earth'' got swiftly sent through the portal before she had a chance to really prove herself a particularly big threat to Leon and Drew, here she gets to act far more comparatively antagonistic and threatening towards Drew after he and Leon interrupt her (solo in this story) efforts at hunting a woolly mammoth calf and very nearly manages to lunge upon Drew before Leon intervenes with the portal.
* AscendedExtra: Played with. The closest thing she had to a counterpart in ''Prehistoric Earth'' was never explicitly referred to as Nala, but she ultimately gets implied to have a lot more to do in this story than her counterpart in Prehistoric Earth.

* KingOfBeasts: She is a cave lion, and a subject of great awe and respect from Leon.

* ShoutOut: Rather appropriately named after the deuteragonists and main love interest in ''Franchise/TheLionKing''.

* AdaptationalAngstUpgrade: Zig-zagged. In this story, her sister Ellie is SparedByTheAdaptation, and both an entire larger herd of woolly mammoths, plus a single adult bull mammoth, are rescued alongside her and Ellie, thus leaving her loneliness issues from the original Prehistoric Park series downplayed at best. But on the other hand, she does end up suffering from PTSD over the traumatic experiences she and her sister underwent involving the savage Kzamm tribe that tried to hunt them, which she never had to go through in the original series.

* BewareTheNiceOnes: Can be quite the GentleGiant in times of peace, but she's still about the same size as a modern day African elephant, and will NOT take kindly to getting antagonized or threatened.
* BigSisterInstinct: Is very protective or her sister Ellie.

* CruelElephant: Downplayed in that she initially behaves in rather hostile fashion when she first sees Jack and Nikolai outside a cave she's about to go walking into...but only because she's trying to defend her wounded sister. And she also proves understandably aggressive in a subsequent encounter with a Kzamm hunting party.

* ShellShockedVeteran: Ends up suffering severe 'episodes' of PTSD at night after the traumatizing experience she and her sister Ellie underwent from nearly getting hunted and killed by a tribe of Kzamm.

A young cave lion rescued in "Ice Time" after being found viciously wounded by an auroch in a cave by Drew and Leon.

* AscendedExtra: Played with. While the closest thing he had to a counterpart in ''Fanfic/PrehistoricEarth'' was never explicitly referred to as Simba, he ultimately gets set up to have a much larger role to play in this story than his technical counterpart in ''Prehistoric Earth'' did by virtue of ending up forming a bond with Leon similar to the kind he was with Diego.

* AdaptationAngstUpgrade: Zig-zagged. In this story, her sister Ellie is SparedByTheAdaptation, and both an entire larger herd of woolly mammoths, plus a single adult bull mammoth, are rescued alongside her and Ellie, thus leaving her loneliness issues from the original Prehistoric Park series downplayed at best. But on the other hand, she does end up suffering from PTSD over the traumatic experiences she and her sister underwent involving the savage Kzamm tribe that tried to hunt them, which she never had to go through in the original series.

* BearsAreBadNews: Zig-zags between this trope and BearyFriendly; whilst he normally isn't aggressive unless provoked, if you do provoke him... God help you.

* HappilyMarried: Is revealed in ''The D-Bags'' to now be happily mated with Shira (to the point that she's now even carrying his cubs).

[[folder:Baloo]]
A male cave bear, who was found, critically injured from an Ape Man hunting party, by Will and Alice in "Ice Time".

* BadassInDistress: He's a large, powerful cave bear... however, he's critically injured and on the brink of death, courtesy of an Ape Man hunting party.

* SnakesAreSinister: Very much averted.

* ButtMonkey: Where to begin? In his first appearance, he's bullied away from the lake by Rommel. And in his second, he gets stuck halfway in a gap in a fence, nearly gets eaten by a Torvosaurus, fails to jump a short distance and lands on Newter (who beats him up) and finally fails to recognize his own reflection and ends up jumping face-first into the Hell Creek crocodile viewing window.

* AmphibianAssault: Beats up Spiny the dimetrodon when he accidentally lands on her over the course of one of his ill-fated attempts at hunting Larry.
* AmphibianAtLarge: She is at least three feet long, which makes her noticeably longer and bigger than most modern day amphibians.
* BigEater: Is noted by Aaron to love to eat sizable portions of the food that she and her kind receive during their feeding times at the park.

* InterspeciesFriendship: Has formed a bond with her primary keeper Aaron.
* PoisonousPerson: Subtly implied in that, while there is no guaranteed explicit information of her being poisonous like some modern species of frog and salamander, her keepers nonetheless wear protective gloves on their hands when handling her and her species, just in case.
* SeldomSeenSpecies: She is a scapherpeton, which does not often come to mind when people think of prehistoric animals prominently featured in most media.
* UseYourHead: The first thing she does to beat up Spiny after he lands on her and incurs her wrath is to ram her head against his chest.

* DistressedDamsel: Is first introduced getting attacked by and rescued from a frenzied float of bracychampsa.

* AscendedExtra: Only appeared in one mission in Prehistoric Earth, aside from a brief BackForTheFinale cameo in the series epilogue. Here, he gets a Prehistoric Park: Extras chapter to himself and Nathanoraptor has implied that he will be a recurring character

* EarlyBirdCameo: He appeared briefly in the Prehistoric Park: Extras story "Two Sides Of One Coin", being bullied away from the Dimetrodon lake by Rommel, [[EstablishingCharacterMoment setting the stage for his later appearances]].

* PteroSoarer: Averted. He's furry, quadrupedal and picks things up with his beak. He's also accurately depicted as a compentent terrestrial walker, much like his species was in real life.

* GentleGiant: Despite giving the rescue team a good startling in his first scene(in all fairness, they startled him first), for an enormous millipede, he's rather placid.

* BloodKnight: Always willing to throw his weight around and prove his might if given the opportunity; [[UncattyResemblance a trait he has in common with Joe]]).

* PintSizedPowerhouse: At a little over ten feet long, he's comparatively small.

* UncattyResemblance: He and Joe both share a self confident swagger that indicate belief in being the toughest one in the room and eager to prove as much in a fight.
