Chomper
See here
Chomper's Parents
Appearances: II | V
Species: Sharptooth (Tyrannosaurus rex)
A pair of large Tyrannosaurus who are fiercely protective of their only son. They act as secondary antagonists in most of both of their film appearances. Their current whereabouts are unknown, but they live away from their son, who lives in the Great Valley.
- Art Evolution: In The Great Valley Adventure, they have ridges running up their necks and down to about their eyebrows. In The Mysterious Island, the ridges are smaller and don't go as far, making their heads look boxier.
- Badass Adorable: They're enormous T. rexes who fight dinosaurs together... and downright adorable when they're with their son.
- Battle Couple: You can bet if one's fighting, the other's about to jump in for a Big Damn Heroes moment if he/she's not preoccupied with another dinosaur.
- Big Damn Heroes: They show up just in the nick of time to save the children from the Plated Sharptooth in The Mysterious Island.
- Contrasting Sequel Antagonist: The original T. rex from the first film was either a Super-Persistent Predator hunting the children, or a sadistic Serial Killer who hunted the kids out of petty revenge and killed for pleasure, depending on whether you follow the film or the novelisation. These two T. rexes are neither. They were just furious about the loss of their egg and leave once they find the hatched Chomper. Further development shows them completely subverting Predators Are Mean trope entirely. The contrast is especially drastic with Chomper's father, who looks almost exactly the same as the original Sharptooth.
- Deadpan Snarker: Chomper's father. "Sometimes I worry about that boy."note Another quote by Chomper's father: "Anything that smells like that couldn't taste very good, anyway!"note
- Good Eyes, Evil Eyes: Their eyes become noticeably rounder and friendlier-looking when they're no longer a threat to the heroes, best seen when Mama smiles at Cera.
- Good Parents: They really do love Chomper and will go to great lengths to protect him.
- Green and Mean: Subverted. They have green scales, are menacing predators, and initially play an antagonistic role, but it turns out they're not bad once you get to know them.
- Happily Married: For a pair of predators, they care for each other just as much as they do their son, to Battle Couple levels. The only tension seen between them is when Mama Sharptooth accidentally bites Papa's snout trying to get Ducky off; Papa snarls in pain at Mama and she snarls back, then they go back to working together.
- Heel–Face Turn: Well, sort of. It is revealed that they are not entirely villainous in The Mysterous Island but are still a danger to the heroes anytime they see them, until Littlefoot risks his life to save Chomper's. After that, they're much more friendly, with Chomper's mother managing to not complain (and smiling) as Cera hugs her leg.
- Made of Iron: Much like all sharpteeth, nothing seems to be able to put them down.
- Mama Bear/Papa Wolf: They're very quick to come to their son's aid if he's in danger. Also the reason they sent Chomper to the Great Valley in the series is to protect him from Red Claw.
- Monster Is a Mommy: When they first appear in in The Great Valley Adventure, the fact there's two sharpteeth sets up the reveal they're Chomper's parents, and only in the Great Valley to find him, not hunt the herbivores. They leave relatively peacefully as soon as they're reunited.
- Non-Malicious Monster: They're carnivores who have to eat, but they're not sadistic and willing to leave individual would-be prey at peace if their son's befriended them.
- Noodle Incident: How Chomper's family made it off the Mysterious Island after the isthmus linking it to the mainland was destroyed is unknown. It's also unknown how they came to meet Ruby, how they came to trust her enough to oversee their son's safety in the Great Valley, and where they are by the time of the TV series.
- Open-Minded Parent: Mama Sharptooth gives a rather deliberate sounding Double Entendre when she finds Chomper hanging around with Littlefoot, suggesting she's aware of her son's taste in friends and doesn't seem particularly bothered by it.
- Pale Females, Dark Males: They have green skin, but Mama Sharptooth's is a noticeably lighter shade.
- Red Eyes, Take Warning: They aren't really villainous, but they are dangerous, and they have the eyes to match.
- Signature Roar: In-universe; Chomper can tell which roars are his mom's or his dad's. They use Frank Welker roars recycled from the original Sharptooth in The Great Valley Adventure, but in The Mysterious Island they sound more like trumpeting elephants. This shows they aren't monsters but rather just large (if still dangerous) animals.
- So Last Season: In their first appearance, they're the main threat of the film, and it takes a whole slew of adults working together to drive them off. In their second appearance, the Plated Sharptooth alone is a match for both of them.
- Terrifying Tyrannosaur: They are a terrifying threat to Littlefoot and his friends, with only the adult herbivores being capable of driving them off. But once they find their long-lost son, they actually prove themselves to be gentle and loving parents, willing to leave the Great Valley in peace. That said, woe to those that threaten their son again, as Ozzy and Strut (and later the Plated Sharptooth) find out the hard way.
- The Worf Effect: The Plated Sharptooth beats both parents in his initial round with them, showing how dangerous he is. Chomper's father gets the better of him in the end, though.
Ozzy and Strut
Appearances: II
Species: Eggnapper (Struthiomimus)
Ozzy voiced by: Jeff Bennett
Strut voiced by: Rob Paulsen
A duo of egg stealers who infiltrate the Great Valley in order to prey upon the smorgasbord of eggs within.
- Ascended Extra: In a way. In the first film, an Eggnapper briefly appears trying to steal Littlefoot’s egg, but gets knocked down by his mother. In The Great Valley Adventure, these two are Eggnappers who act as the main antagonists.
- Big Brother Bully: Ozzy does not listen to Strut about his desire to eat plants and forces him eat a diet comprised of eggs.
- Big Bad Duumvirate: Their theft of Chomper's egg is what brings his parents to the Great Valley.
- Bumbling Sidekick: Strutt mostly seems to go along with what Ozzy says, although he does come up with the idea to kill Littlefoot by throwing him off the cliff.
- Butt-Monkey: Both of them, though Strut usually gets the worst of it.
- Determinator: Nothing will stop Ozzy from getting his eggs.
- Evil Brit: Ozzy has a British accent, and is the meaner of the two.
- Evil Duo: A villainous duo of egg stealers; one is a bully and the other is bumbling.
- Evil Egg Eater: Their entire agenda is to feast on the dinosaur eggs despite the fact they could easily survive on plants like other plant-eating dinosaurs (something Strut himself points out). Ozzy even sings a Villain Song of how much he loves eggs.
- Evil Is Petty: Ozzy admits that he's incredibly picky when it comes to his diet (which is just eggs) and would not even allow his brother to eat plants just to stave off the hunger.
- Exit, Pursued by a Bear: They get chased off by Chomper's parents in the end.
- G-Rated Drug: The two treat eggs like it's some kind of drug, with Ozzy being a full addict bullying his brother back into old habits despite the latter trying to go clean with a diet of plants.
- Large Ham: When you're voiced by Jeff Bennett and are obsessed with eggs, of course you'll have a large ham to go with it.
- Laughably Evil: Assholes for sure, but they are hilarious to watch, especially with Ozzy singing his obsession with eggs and Strut trying something else to eat other than eggs.
- Jerkass: Ozzy to Strut. He kicks and hits his brother several times and when both are getting cornered by fire, he orders Strut to wait his turn while Ozzy saves himself first.
- Not-So-Harmless Villain: For most of the film, Strut was seen as the Butt-Monkey and was constantly being pushed around by his older brother. However, he proves to be just as devious as Ozzy by suggesting they throw Littlefoot off the Great Wall.
- Uncertain Doom: It's not clear if Chomper's parents killed them or not.
- Vegetarian Carnivore: Ozzy and Strut are both Struthiomimuses. Strut is more content with eating plants, while Ozzy is obsessed with eating eggs. Their conflict over their diets seems to be a reference to the debate paleontologists had over the Struthiomimus's feeding habits since the early 20th century, though Strut would win in the long run since Ozzy's strict diet of eggs would be a death sentence for them as Struthiomimus is widely accepted to be an omnivore that mostly ate plants, though it might have eaten eggs if they were available.
- Villain Song: 'Eggs', which is Ozzy talking about his love of eggs and how Strut should eat them instead of plants.
- Would Hurt a Child: Not only does Strut suggest they kill Littlefoot by throwing him off of a cliff, Ozzy attempts to strangle Chomper, who had hatched just hours prior.
- Yellow Eyes of Sneakiness: Strut has yellow sclerae and sneaks about to steal food, often at night. Ozzy's eyes are orange, putting him halfway between this and Red Eyes, Take Warning, showing he's the nastier and more dangerous of the two.
Debuted in The Land Before Time III: The Time of the Great Giving
Hyp, Nod and Mutt
"Everything's better when you're big."
Appearances: III | TV series
Species: unidentified (Hypsilophodon, Nodosaurus, and Muttaburrasaurus, respectively)
Hyp voiced by: Whit Hertford (III) | Mikey Kelley (TV series)
Nod voiced by: Scott Menville
Mutt voiced by: Jeff Bennett
A group of three bullies who terrorize Littlefoot and his friends simply because they're bigger than them.
- Aesop Amnesia: They're back to being troublemakers in the TV series, but at least seem to have learned somewhat.
- Big Bad Ensemble: While they're the main antagonists to the children in Time of the Great Giving, the bigger problems come from Topps's taking charge of the valley and the drought itself.
- Big, Thin, Short Trio: Mutt (big), Hyp (thin), and Nod (short).
- Brains and Brawn: Hyp's the brains, Nod and Mutt are the brawn, but especially Mutt.
- Butt-Monkey: Mutt gets slapped around a lot.
- Card-Carrying Villain: Card-Carrying Bully would be more like it since none of them seem to call themselves "evil" or "villains". Hyp even admits to being a bully.
- Deadpan Snarker: Hyp is quite the wiseass before he mellows out.
- Everyone Has Standards: Hyp is the lead bully, but even he doesn't like anyone sticking out their tongues.
- Frame-Up: Get Littlefoot in trouble by pushing him into the water off a low cliff, making the scarce resource scarcer due to the big splash. Littlefoot being Littlefoot doesn't say it was them, just that he'd been playing and fell.
- Freudian Excuse: Hyp's dad was even more hardass than Topps. And Topps is one of the adults to seriously call Hyp's dad out on it.
- Gang of Bullies: They're very keen on antagonizing Littlefoot and his friends for being smaller and weaker than they are throughout Time of the Great Giving. While they learn their lesson by the end of the film, they still retain a mean streak when they show up in the TV series.
- Heel–Face Turn: They start out as a bunch of bullying jerks to Littlefoot and his friends, yet they do come through in the end and helps save everyone from the Sharpteeth.
- Informed Species: Hyp doesn't even vaguely resemble Hypsilophodon (known for being a Ridiculously Cute Critter among dinosaurs and, contrary to the group's big villain song, very small in size), while Mutt looks more like some kind of hadrosaur than a Muttaburrasaurus. The only one who actually does resemble the dinosaur he's based on is Nod.
- A Lizard Named "Liz": All three seem to derive their names from their genera: Hypsilophodon, Nodosaurus, and Muttaburrasaurus.
- Original Position Fallacy: They think they have the right to do what they want to Littlefoot and his friends because they're bigger than them, but it's pointed out their victims will inevitably grow bigger than them.
- The Napoleon: Hyp's obsession with being the biggest and meanest guy around clearly rises from insecurity about how he's not actually very big - he's significantly smaller than his two cronies, and is only bigger than the Gang of Five because he's older; the gang pointing out that most of them are species which grow much larger than his provokes Hyp to deliver a surprisingly dark Implied Death Threat. And of course there's the fact that his own father tends to buly him into submission, leaving him no recourse but to do the same to those he can intimidate.
- The Social Darwinist: Believe they can do whatever they want to those smaller than them.
- Took a Level in Kindness: They become much nicer by the end of the movie.
- Villain Song: 'When You're Big', a possible contender for the best song in the series.
- "Well Done, Son" Guy: Hyp, to the point that he still idolizes his father, despite his abusive ways. This turns out to be why he's such a bully in the first place; it's the only way he can interact with others, because it's all his father ever gave him.
Mr. Clubtail
"Mornin', kids. Nice day for a treestar!"
Appearances: III | V | VII | XI | XII | XIV
Species: Clubtail (Ankylosaurus)
Voiced by: Rob Paulsen (III, XI, and XII) | Jeff Bennett (V)
An older resident of the Great Valley who's a common recurring background character in the series. He's one of the few background characters who takes on more important roles in the story at times, and virtually the only one with a given name. He lives in the Great Valley with at least one young family member.
- Big Eater: He’s seems to be gluttonous, as he eats the day’s first treestar in film five without a second thought,
- Cool Old Guy: When he’s not grumpy he can be a very nice man, as seen when he politely greets the gang at the beginning of film five.
- Depending on the Writer: He’s generally a gruff man with a soft side to him, although sometimes he isn’t gruff at all, like in The Mysterious Island.
- Tail Slap: His clubtail— or “bopper”— is a handy tool for fighting off sharpteeth, as seen in Time of the Great Giving. He seems to be able wield it with a great degree of control, as he’s able to give Guido a demonstrative smack without significantly harming him despite Guido being much smaller and lighter than he is.
- Tough Armored Dinosaur: A gruff, irritable but good-natured Ankylosaurus who isn't afraid to take action in a crisis.
Hyp's Father
Appearances: III
Species: unidentified (Hypsilophodon)
Voiced by: Nicholas Guest
- Abusive Parents: One look at him and Hyp is terrified. His yelling-based method of parenting is clearly the reason Hyp feels the need to pick on smaller dinosaurs, and makes Cera's dad realize that he himself yells too much.
Fast Biters
Appearances: III
Species: Fast Biter (Velociraptor)
Voiced by: Frank Welker
A pack of velociraptors that attacks the Gang of Five, the bully trio, and their guardians at the climax of the film.
- Made of Iron: They take quite a lot of punishments, being kicked around by the adults, buried in rocks and even swept away by a flood, and yet they survive the movie.
- Oh, Crap!: One of them has this reaction when he realizes they are about to get swept away by a flood.
- Raptor Attack: They are typical Jurassic Park-style raptors.
- Watch Where You're Going!: Three of them try to pounce on Hyp's father and bump into each other.
- Yellow Eyes of Sneakiness: They all have yellow sclerae and are vicious creatures.
Debuted in The Land Before Time IV: Journey Through the Mists
Ali
"It takes all sorts to make our world."
Appearances: IV | TV episode "The Brave Longneck Scheme"
Species: Longneck (Apatosaurus)
Voiced by: Juliana Hansen (IV) | Nika Futterman (TV series)
A young female Apatosaurus from the land known as the Valley of the Mists. She is a Farwalker, along with the rest of her herd, and is constantly traveling.
- By the Lights of Their Eyes: How she is introduced.
- Distaff Counterpart: Ali looks almost exactly like Littlefoot. Lampshaded by Petrie, who mistakes her for a second Littlefoot when he first sees her.
- Distress Ball: Ali seems to uncharacteristically buy Rhett's bald-faced lies to the point that she'll side with him over her old friends Littlefoot and Cera. Not only that, it's shown that Ali doesn't even always like being around Rhett, but doesn't seem willing to stand up to him, which is a far cry from her bold personality from the fourth film.
- Fantastic Racism: Not as bad as Mr. Threehorn gets, but she initially wasn't comfortable interacting with dinosaurs who weren't longnecks.
- Genki Girl: Has a mild case of this when she first meets Littlefoot, gleefully hiding from him and playing pranks on him before they've even said hello. She later cheers him up from a low mood by a pulling a series of goofy faces. This attitude is quick to disappear when the other characters show up though.
- Guest-Star Party Member: In Journey Through the Mists.
- Innocent Blue Eyes: A nice, generally sweet tempered girl. Her discomfort around other species is a result of lack of experience in interacting with them.
- One Head Taller: Despite being a near identical Palette Swap of Littlefoot, Ali does appear to be a little shorter. e.g: [1]
- Pale Females, Dark Males: Ali is more pinkish than Littlefoot, who is more grayish.
- Pink Means Feminine: Her skin tends to have a pink tinge, which the main physical difference between her and Littlefoot.
- Walking the Earth: Her herd is migratory, after their homeland was ruined by constant rain and floods.
- What Happened to the Mouse?: Until she eventually popped up briefly in the TV show, fans spent a long time wondering if Ali would ever return, especially since the fourth movie had pretty much promised she would. A change in directors between the fourth and fifth movies may have been the cause of this, though it's unknown what, if any, kind of plans regarding Ali's return originally existed.
Old One
Appearances: IV | TV episode "The Brave Longneck Scheme"
Species: Longneck (Apatosaurus)
Voiced by: Carol Bruce (IV) | Jessica Walter (TV series)
The leader of a group of wandering longnecks called the farwalkers, she brings word of the outside world to the Great Valley and identifies a sickness that has overtaken Littlefoot's grandfather.
- Everyone Calls Him "Barkeep": Referred as the old one due to her age, but she has no other known name.
- Good Scars, Evil Scars: She has deep scars running down the left side of her face. While it's never explained where she got them, they appear to be claw mark scars from some sharptooth she encountered in her past.
- Reasonable Authority Figure: Despite her flaws as a leader, she clearly has the best interest of her herd in mind, and is shown to be happy when finding that a sharptooth can get along with plant eaters.
- Took a Level in Jerkass: In the TV series, she and her herd are prettily willing to kill, or at least injure, Chomper.
- Walking the Earth: She's in charge of a migrating herd.
- Would Hurt a Child: In an episode of the TV series, she and her herd chase and eventually corner Chomper over a misunderstanding. Chomper, sounding close to tears, begs that they don't hurt him, and after a few moments of marveling over the fact that they're dealing with a talking sharptooth, she and her herd decide they still want to kill him. Given the fact that Chomper is both very outnumbered and very tiny compared to the longneck herd this seems extremely out of character for Old One. To be fair, Old One hesitates after hearing him talk, and only goes through with it after another herd member convinces her that it's for the good of the valley (and afterward, she still seems very reluctant).
Ichy and Dil
Ichy-"I do all the REAL work around here. I'm the eyes!" Dil-"So? I'm the teeth!"
Appearances: IV
Species: Sharpbeak (Ichthyornis) and Bellydragger (Deinosuchus), respectively
Ichy voiced by: Jeff Bennett
Dil voiced by: Tress MacNeille
A squabbling male Ichthyornis and female Deinosuchus who partner together to hunt prey in the Valley of the Mists. They act as the main antagonists of the fourth film. Their whereabouts are unknown.
- Ambiguous Situation: We never learn what happened to them at the end of the movie. Fed up with him, Dil sent Ichy flying off in one hit of her tail, right before being chased by an hungry plesiosaur. We don't know if either of them survived their ordeal.
- Artistic License – Paleontology: Ichy shouldn't really be interested in hunting dinosaurs or living inland like he is—Ichthyornis was a coastal, seagull-like predator that would almost certainly have eaten tiny marine creatures, as well as occasional carrion. Otherwise, he and Dil are rarities in the film series in that they both manage to avert this trope for the most part; while they're obviously stylized to make them look more villainous, they at least manage to look and move like the animals they're supposed to be (no doubt because both resemble animals that are still around today: namely, birds and crocodiles).
- A Twinkle in the Sky: While not quite there, Ichy gets sent flying pretty far courtesy of a smack from Dil's tail.
- Big Bad Duumvirate: The main antagonists of the fourth film, who are always seen together, in spite of their mutual dislike of each other.
- Blind Mistake: Dil's poor eyesight causes her to bump into things without Ichy to guide her. It also makes her nearly swallow Ichy, which proves to be the last straw for him.
- Brains and Brawn: Ichy is the planner, Dil is the muscle. They're useless without each other, as Ichy is too small to accomplish much and Dil is nearly blind.
- Bullying a Dragon: A quite literal example. Ichy is the more standoffish and antagonistic of the two, constantly insulting and belittling Dil (a giant crocodile), even though she could easily crush him like a bug, even if she didn’t intend to straight up kill him (given her poor eyesight), like when she almost eats him by accident during the climax.
- Even Evil Has Loved Ones: When one of Ichy’s verses in their Villain Song takes a jab at Dill by saying she’s as ugly as her dad, she angrily bares her teeth at him.
- Exit, Pursued by a Bear: After 'parting ways' with Ichy, Dill is chased off screen by a very hungry looking plesiosaur.
- Feathered Fiend: Icky, who is a bird and along with Dil is the villain of the film.
- Feeling Their Age: Implied with Dil, whose surly voice and poor eyesight suggest that she’s way past her prime. This could also explain why she’s constantly straying away from water, as she can longer compete with younger and more powerful Deinosuchus.
- Laughably Evil: Their arguing with each other and suffering bad luck and Amusing Injuries is Played for Laughs, although they do pose a serious threat to the main characters.
- Like an Old Married Couple: Because of their dependency on each other, they spend a lot of time together. However, they frequently get into arguments and take jabs at each other. Their first argument was about who does the most work to get food, which they claim was themselves instead of their partner.
- Meaningful Name: Ichy stems from "Ichthyornis" and is pronounced like "icky", reflecting his personality. Dil appears to be derived from "crocodilian".
- The Napoleon: Ichy is a small Ichthyornis and tends to get very snappish with Dil.
- Never Smile at a Crocodile: Dil, although she's a bit less competent than most.
- Not-So-Harmless Villain: They alternate between being used for comic-relief and being very close to eating the heroes.
- Pet the Dog: Dil gets this near the end of the film as she apologizes when she almost eats Ichy.
- Red Eyes, Take Warning: Dil's eyes are bright red and she's a serious threat to the main characters.
- Shorter Means Smarter: Ichy is the smallest of the duo and the brains of the outfit.
- Shout-Out:Dil: "One of these-" *hits tree* "-days, Ichy-" *hits tree* "One of these-" *hits tree* "... Oh, forget it." *hits tree*
- Smug Snake: Ichy moreso than Dil, being the schemer of the two who's far too full of himself for his own good. Dil is also pretty smug, though.
- Super-Persistent Predator: They pursue the heroes throughout the film, intent on making a meal of them despite being foiled multiple times. Presumably, their humiliations add an extra motivation of spite and revenge to the original goal of just eating them for food.
- Teeth-Clenched Teamwork: They are partners, not friends. They make it clear they're only together out of necessity.
- Tiny Guy, Huge Girl: Ichy is a small bird, while Dil is a massive crocodilian.
- Toothy Bird: Justified, as Ichy is an Ichthyornis, which had teeth in real life.
- Uncertain Doom: The last we see of Dil is her getting chased by a hungry plesiosaur. It's not clear if she managed to escape it.
- Villain Song: 'Who Needs You', all about how they can't stand each other, despite the fact that neither can survive without the other. It's done in a vaudeville style.
- Yellow Eyes of Sneakiness: Ichy has these, to contrast he is the more cunning but less physically threatening one of the duo while Dil, the muscle, gets the red eyes.
Archie
Appearances: IV
Species: unidentified (Archelon)
Voiced by: Charles Durning
An elderly resident of Ali's flooded homeland, the Land of Mists. He helps Littlefoot when the little Longneck gets isolated from his friends due to a cave-in.
- Artistic License – Paleontology: Archelons were a sea dwelling species, and probably never inhabited far-inland caves even if those caves had water in them.
- Cool Old Guy: He's rather old, but helps Littlefoot fighting off Ichy and Dil.
- Guest-Star Party Member: Unlike Ali, Archie only joins the group until they leave the cave system that leads up to the Land of Mists.
- The Hermit: He lives in a cave, and so doesn't usually see too many guests.
- Jerk with a Heart of Gold: At first, he tries to scare Littlefoot away, but he quickly mellows out once he sees that Littlefoot is just a lost kid and agrees to help him.
- A Lizard Named "Liz": An Archelon named Archie.
- What Happened to the Mouse?: He doesn't go with the group in the Land of Mists and stays in the cave system. The heroes don't get to meet him back, even when they leave the Land of Mists.
- Wise Old Turtle: He's quite elderly, dispensing valuable wisdom to the main characters and even comes to their rescue on a number of occasions.
Tickles
Appearances: IV
Species: unidentified mammal
Voiced by: Frank Welker
The first mammal to have any significance in a series about dinosaurs, Tickles is a small rodent-like creature found by Spike in the Valley of the Mists in the gang's search for the night flowers. Taking a liking to the gang, he joins them on their travels around the valley until they decided to leave back for the great valley, at which point they parted company. He's probably still in the Land of Mists.
- But Now I Must Go: Chooses not to return to the Great Valley with the dinosaurs, presumably because his main family was still in the Valley of the Mists.
- Cheerful Child: Has a perpetual smile, and doesn't seem to be any more mature then the other dinosaurs. Still counts as Vague Age, though.
- Known Only by Their Nickname: Since he can't talk normally, Ducky named him Tickles since he's the only one with fun hair on his body.
- Meek Mesozoic Mammal: Played with. While he is prone to fleeing away from larger animals as the rest of his kind are, he has a moment of bravery when he saves Ducky from being eaten by Ichy and Dil.
- Nice Mice: He resembles a mouse, and is friendly and helpful towards the Gang.
- Odd Friendship: Even though they're only together for a little while, he and Spike seem to hit it off pretty well with each other.
- Pint-Sized Powerhouse: While normally seen rolling rocks only a little bigger than himself, when he can pick up Dil's tail and drag it around without much difficulty, that's more of a surprise given he's smaller than Ducky.
- The Unintelligible: Speaks only in squeaks, though the others seem to understand him fine.
- What Happened to the Mouse?: Literally, since he's a prehistoric mouse. He hasn't returned in any of the sequels or the TV series, despite the return of so many other characters. He probably still lives in the Valley of the Mists.
Debuted in The Land Before Time V: The Mysterious Island
Elsie
Appearances: V
Species: Swimming Longneck (Elasmosaurus)
Voiced by: Christina Pickles
An inexplicably British plesiosaur that accidentally frightens Chomper and Littlefoot. She gladly helps our dinosaurian heroes relocate their parents.
- Artistic License – Paleontology: Her portrayal has... several problems, the least of which being a shark fin being on her head for no reason. In this movie she is essentially just a sauropod with flippers. Plesiosaurs were only very distantly related to dinosaurs at all, much less longnecks. She's also improbably huge. Oddly, a (relatively) much more accurate plesiosaur appeared in the previous movie.
- The Cameo: She may or may not be one of the Elasmosaurs that swim by in the beginning of the ninth film.
- Horse of a Different Color: Her main contribution to the film is giving the kids a safe ride back to the mainland.
- Interspecies Romance: Downplayed. She finds Grandpa Longneck good-looking and muses that they'd make "quite a pair" together if he had flippers.
- A Lizard Named "Liz": An Elasmosaurus named Elsie.
- Nice Girl: Is very kind and helpful, immediately volunteering to reunite the kids with their parents.
- Stock Ness Monster: Her neck is in the same pose as the classic picture.
- Vegetarian Carnivore: Plesiosaurs were carnivorous. We never see Elsie eat, but she has noticeably flat teeth, and appears to be just an aquatic version of Littlefoot's grandparents.
Plated Sharptooth
Appearances: V
Species: Plated Sharptooth (Giganotosaurus)
An unnamed, vicious Giganotosaurus living on the Mysterious Island. He acts as the main antagonist of the fifth film. He's drowned — we assume — after being pushed off a cliff into the ocean, similar to a certain other Sharptooth we've seen before.
- Big Bad: Of the last act of Mysterious Island.
- Character Tics: He bites into stuff and chews it, as if tasting. He does this with a bush the kids were hiding in, then the patch of stinky plants, and finally a chunk of dirt. The chewing gives him a chance to show off his extra-long and pointed teeth for the audience.
- Conflict Killer: His arrival kills two conflicts in the story. First, Cera doesn't trust Chomper, but the two both save each other from the Plated Sharptooth and so become friends again. Second, the kids are worried Chomper's parents will eat them, but Littlefoot saving Chomper from the Plated Sharptooth earns their respect.
- Darker and Edgier: Sharpteeth, particularly unnamed ones, are generally portrayed as either friendlier than they seem or incompetent villains, but the Plated Sharptooth harkens more to the vicious, relentless threat of the original Sharptooth. He holds the distinction of being the first character to draw visible blood onscreen: he slashes Chomper's father's nose with his claws◊, and then slashes his mother's leg with his toes. And no—unlike with the original Sharptooth, it didn't get edited out this time.
- Determinator: Most sharpteeth in the series will run in fear the moment that adult flateeth make the scene. The Plated Sharptooth was perfectly willing to stand and fight two other adult sharpteeth at the same time.
- Disney Villain Death: Falls right into the ocean.
- Hellish Pupils: Both he and Chomper's parents have red eyes, so to make it extra clear he's a bad guy compared to them, the Plated Sharptooth's pupils are slitted instead of round.
- Implacable Man: While not quite as unstoppable as the sharptooth of the first film, he's displayed unusual persistence by jumping over chasms and fighting off other sharpteeth in an attempt to get at the heroes.
- It Can Think: Since the Plated Sharptooth apparently can't talk like Chomper's parents, he initially comes off as a mindless predator. However, he shows problem-solving abilities when, unable to reach the kids where they're hiding under a rock, he lifts up the rock to get at them.
- Knight of Cerebus: Calls back more to the original Sharptooth in terms of sheer viciousness. Aside from one comical moment where he accidentally bites his own tail, tearing up as he does so, the Plated Sharptooth is much more serious than others of its kin.
- No Name Given: The movie never gives him a name, but the credits refer to him as 'The Plated Sharptooth'.
- Red Eyes, Take Warning: His eyes are drawn in an unusually animalistic manner, with less expression, more prominently slitted pupils, and dark marks under his eyes. These mark him out as an unusually dangerous sharptooth.
- Taking You with Me: Similar to how the original Sharptooth nearly dragged Petrie into the water with him when he falls from the precipice in the first film, the Plated Sharptooth knocks Chomper off a cliff and into the ocean along with him and nearly causes him to drown. After emerging from the water, he sees Chomper and goes for another bite, but Chomper survives this with Littlefoot's help.
- Uncertain Doom: The last we see of him, he's roaring in panic as the current drags him out to sea—relatively unharmed, but with not-so-bright odds of surviving.
- The Voiceless: He's introduced in the same movie we learn Sharpteeth have their own language, but though he roars and growls a lot, if he can talk he doesn't seem to bother with Chomper's parents.
Swimming Sharptooth
Appearances: V
Species: Swimming Sharptooth (unspecified shark)
A shark who lives around the Mysterious Island and the secondary antagonist of the fifth film.
- More Teeth than the Osmond Family: Being a shark, it naturally has a large mouth full of scary teeth. It's only when Cera sees them that she realizes it's trouble and names it a swimming sharptooth.
- Sea Monster: From the point of view of the children at least, that thing is a gigantic monster.
- Shark Fin of Doom: The children are terrified of seeing its fin. When they see Elsie's head fin sticking out the water at the end of the movie, they mistake her for the Swimming Sharptooth and are scared for their lives.
- Threatening Shark: A terrifying prehistoric shark that tries to eat the children.
Debuted in The Land Before Time VI: The Secret of Saurus Rock
Doc
"Have it your way, kid."
Appearances: VI | TV episode "The Lone Dinosaur Returns"
Species: Longneck (Diplodocus)
Voiced by: Kris Kristofferson (VI) | Jeff Bennett (TV series)
A loner Diplodocus who fights away sharpteeth, and Littlefoot's idol. Littlefoot believes he is the legendary "Lone Dinosaur" of myth. He's a wanderer, and constantly travels from place to place.
- Clint Squint: He's rarely seen without one, just like the actor he's a clear Expy of.
- The Drifter: Leads a nomadic lifestyle.
- Expy: The dinosaur version of Clint Eastwood.
- Fantastic Racism: When he shows up in the series, he refuses to accept Chomper might be a good guy due to him being a Sharptooth. However, he ultimately learns the error of his ways when the little guy helps save his 'lady friend'.
- Good Scars, Evil Scars: A thin, jagged one over the right side of his face.
- Jerk with a Heart of Gold: In the TV series, at least. In his first appearance, he's more of a silent, enigmatic wanderer whose moralities— outside of fighting sharpteeth— are unknown.
- The Jinx: The events of the sixth film cause the Great Valley residents to pin the blame on his arrival to the valley as a harbinger of bad luck. While he doesn't particularly seem to care about the negative reputation he has, it is a stigma that's stuck with him all the way up to his reappearance in the TV series.
- Meaningful Name: Likely comes from his genus name of Diplodocus.
- No Celebrities Were Harmed: Very obviously Clint Eastwood if he were a sauropod.
- Red Baron: The Lone Dinosaur
- Riddle for the Ages: Is Doc the Lone Dinosaur of legend? An answer is never given, and there's evidence that both supports and denies this claim. The film leaves it ambiguous wether the fight sequence that plays out during grandpa longneck's story is a depiction of a real event or simply Littlefoot's visualization. Curiously, the 'Biggest, Meanest Sharptooth' is a dead ringer for the Sharptooth from the original film, someone Littlefoot has met before, while the Lone Dinosaur looks just like Doc, who he's about to meet.
- The Stoic: It's hard to tell what he feels half the time. Even in a clear moment of displeasure, like when he finds out about Littlefoot's friendship with Chomper, he seems self-restrained in his emotions.
- Tag Along Kid: Doc seems to see Littlefoot as this. While he doesn't discourage Littlefoot from trying to imitate him and does seem to genuinely like him, he usually has other things on his mind than trying to impress a local longneck boy.
- Warts and All: Doc fits this trope from the time he condemns Littlefoot's friendship with Chomper until the time he repents for it.
Dana and Dinah
Appearances: VI
Species: Three-horn (Triceratops)
Dana voiced by: Nancy Cartwright
Dinah voiced by: Sandy Fox
Two rambunctious threehorn hatchlings with a knack for getting in trouble. The two are Cera's niece and nephew, despite the fact that none of her siblings appear in the sequels.
- Annoying Younger Sibling: For Cera—although she's technically their aunt and not their older sister.
- Baby Talk: They talk in an unintelligible babble. Humorously lampshaded by Cera as she tearfully remembers their 'first words'.
- Can't Live with Them, Can't Live Without Them: Despite how annoyed Cera often is with them, she's legitimately distraught when she thinks something bad has happened to them.
- Chuck Cunningham Syndrome: They disappear after Saurus Rock. Presumably, they went back to live with their parents.
- Cousin Oliver: Seemingly introduced as this, although they quickly disappear after their first appearence.
- Fearless Infant: They are totally oblivious to any kind of danger! They almost fall to their deaths while rolling around on top of Saurus Rock.
- Parental Abandonment: Their parents are nowhere to be seen. Interestingly, despite one of them likely being a sibling of Cera's, they don't resemble Cera at all.
- Practically Different Generations: They're the babies of the bunch and their aunt Cera babysits them. Despite Cera looking within of age range to be mistaken for their older sister.
Meanest Sharptooth
Appearances: VI
Species: Sharptooth (Tyrannosaurus rex)
- Disney Villain Death: The Lone Dinosaur defeated him by pushing him off a cliff.
- The Dreaded: He had a reputation for being extraordinarily fearsome, even for a Sharptooth. Aside from the Lone Dinosaur, all of the longnecks fled in terror when he showed up in the Great Valley.
- Informed Ability: According to Grandpa Longneck, he was "the biggest, meanest, most ferocious Sharptooth ever". However, from what is shown in the flashbacks, he didn't come across as particularly worse than most of the other Sharpteeth of the movie series (especially the original Sharptooth, or even the Plated Sharptooth). To be fair, he did manage to severely injure the Lone Dinosaur, push him to the ground and almost kill him.
- Minor Injury Overreaction: Only in Littlefoot's dream, though. When Littlefoot whips him in the leg with his tail, the Meanest Sharptooth runs away, hopping on one foot in pain.
- Posthumous Character: He only appears in flashbacks, having been killed by the Lone Dinosaur a long time ago.
- Red Eyes, Take Warning: He has red sclerae and is considered one of the most dangerous Sharpteeth to ever live.
- Terrifying Tyrannosaur: He was a Tyrannosaurus rex and was said to be the most formidable of all Sharpteeth.
- The Worf Effect: He is said to have been a particularly powerful Sharptooth, so his defeat by the Lone Dinosaur is a proof of the latter's badassery.
- Would Hurt a Child: He tried to attack a mother longneck and her child.
Saurus Rock Sharptooth
Appearances: VI | TV episode "The Lone Dinosaur Returns" (flashback only)
Species: Sharptooth (Allosaurus)
Voiced by: Danny Mann
An Allosaurus encountered near Saurus Rock, and the sixth film's designated Sharptooth antagonist. He is defeated by Littlefoot's grandpa and Doc working in tandem.
- Animals Not to Scale: He appears to be roughly the same size as the various T. rexes that have shown up throughout the franchise. That's positive massive for an Allosaurus, and much more in line for the closely related Saurophaganax.
- Big Bad: He serves as the main antagonist of the movie The Secret of Saurus Rock.
- The Cameo: He briefly shows up during a flashback in the episode "The Lone Dinosaur Returns" of the TV series.
- *Drool* Hello: Cera realizes that the Sharptooth is behind her when his saliva falls on her head.
- Help, I'm Stuck!: Twice. He first gets his head stuck in a tree while trying to eat Dinah and Dana. Later, he manages to free himself and goes after Littlefoot and his friends, but he gets stuck between two trees during the chase, though this time he quickly gets free.
- Informed Species: Doesn't look much like an Allosaurus, all things considered. In addition to being too big, it lacks the real animal's brow horns and has only two fingers on each hand like a tyrannosaur.
- Interspecies Friendship: Downplayed, but he teams up with a Tyrannosaurus rex to fight Doc and Grandpa Longneck during the climax.
- Made of Iron: He survives a pretty long fall from a canyon.
- Not Quite Dead: He falls to his apparent death halfway through the movie, but he's later revealed to have survived.
- Palate Propping: After his supposed death, Littlefoot uses a club to open his mouth while he tries to get one of his teeth. Unfortunately, he turns out to be very much alive and easily breaks the club.
- That's No Moon: When Littlefoot and his friends enconter him, they mistake his leg for a tree at first.
- The Tooth Hurts: Littlefoot attempts to pull out one of his teeth, which seems to hurt him. After Doc and Grandpa have defeated him, his tooth falls off near Littlefoot.
- Use Your Head: He breaks a rock on his path by hitting it several times with his head.
Canyon Sharptooth
Appearances: VI | TV episode "The Lone Dinosaur Returns" (flashback onlynote )
Species: Sharptooth (Tyrannosaurus rex)
A Tyrannosaurus who lives near Saurus Rock, and the secondary antagonist of the sixth film. It's defeated by Littlefoot's grandpa and Doc working in tandem.
- Adaptation Species Change: In the TV series, this Sharptooth is portrayed as another Allosaurus during Littlefoot's flashback of the two Sharpteeth's battle against Doc and Grandpa.
- Ambiguous Situation: It's unknown whether the Canyon Sharptooth is supposed to be the ghost of the Meanest Sharptooth or if it's a separate entity.
- The Cameo: It briefly shows up during a flashback in the episode "The Lone Dinosaur Returns" of the TV series, albeit as an Allosaurus rather than a T-rex.
- Diabolus ex Nihilo: It appears only towards the end of the movie out of nowhere, with no foreshadowing whatsoever. However, this would change if it was the ghost of the Meanest Sharptooth.
- Interspecies Friendship: Downplayed, but it teams up with an Allosaurus to fight Doc and Grandpa Longneck during the climax.
- Red Eyes, Take Warning: Like most of the Tyrannosaurus rex in the movie series, this one has red sclerae and is a dangerous predator.
Debuted in The Land Before Time VII: The Stone of Cold Fire
Pterano
"Petrie, I'm heartbroken. Don't you recognize your dear old uncle?"
Appearances: VII | TV series (occasionally mentioned)
Species: Flyer (Pteranodon)
Voiced by: Michael York
An ambitious, cunning pterosaur who takes an interest in the story of the Stone of Cold Fire. He's Petrie's maternal uncle, and an antagonist for much of the seventh film. He's been banished from the Great Valley for several years as punishment for kidnapping Ducky, and his current whereabouts are unknown.
- Affably Evil: Despite his nastier qualities and his rampant ego, he ultimately doesn't mean to hurt anyone and atones for his actions by the end of the film.
- Anti-Villain: Not really evil per se, but certainly selfish and very reckless. While he has put people in danger before, he never means to do so and wishes no harm on anyone.
- The Atoner: Eventually, he agrees that he has to be held accountable for his actions and promises that, after the end of his banishment, he will return to the herd and prove that he can be trustworthy.
- Big Bad: Of Stone of Cold Fire, though he doesn't stay that way.
- Cool Uncle: Petrie thinks he is.
- Dirty Coward: Accused of being one, after his disastrous leadership.
- Dub Name Change: In the Finnish dub, he is known as Lentola (lento is finnish for "flight").
- Even Evil Has Loved Ones: He has a sister and a couple nieces and nephews, one who adores him. However, his sister is less than friendly when he shows up.
- Even Evil Has Standards: He may be arrogant and somewhat nefarious, but he draws the line at harming children. When he first mentions it, it sounds like Pragmatic Villainy, but later he expresses worry when he loses Ducky and genuine horror when Sierra declares that the minute they become leaders he's going to throw the kids to the sharpteeth. Lampshaded by his sister, who states that while he's done many bad things, she knows he would never let Rinkus and Sierra harm Ducky.
- Evil Brit: He's one of only a few characters in the series with a clear British accent, and is the main villain for most of his movie.
- Evil Uncle: But he has a Heel–Face Turn.
- The Exile: At the end of Stone of Cold Fire, he's exiled from the Great Valley for several years thanks to his past actions and kidnapping Ducky. However, since he helped save the children, his sentence was lessened significantly.
- Godhood Seeker: He seems to believe the Stone of Cold Fire will give him power of this nature. It doesn't.
- Hated by All: Despite the fact that he always has good intentions, his inflated ego and inability to own up to his mistakes have caused others to dislike and distrust him, including his sister. His henchmen only seem to put up with him, because they want the "power" of the "stone of cold fire" for themselves. When he is exiled from the Great Valley as punishment for his actions, then asks if it will be fair when he mentions he’ll be alone and defenseless, the herd shouts Yes together in unison.
- Heel–Face Turn: In the end, he saves the children and abandons his former ways.
- "I Am Great!" Song: "Very Important Creature", a song where he proclaims that everybody would be better off if he were in charge.
- It's All About Me: His Villain Song, "Very Important Creature" highlights this. He's motivated by a big superiority complex.
- Jerk with a Heart of Gold: He may be selfish and arrogant, but he's not heartless and he does have redeeming qualities deep down, as Ducky points out.
- Knight of Cerebus: Thanks to his having gotten a large number of the herd killed, he brings a much more personal threat to the adults of the Great Valley than any villain before him.
- Large Ham: Comes with the territory of being played by Michael York.
- A Lizard Named "Liz": Pretty obviously derived from his genus name of Pteranodon.
- My God, What Have I Done?: He has this response a lot. Most notable is the one listed directly below. Simply watch his expressions and body language during the fast biter attack.
- My Greatest Failure: Pterano had once unintentionally led a group of followers into a fast biter (raptor) ambush, where everyone but himself was killed. He seems very haunted by this event.
- Nephewism: While he’s certainly not above manipulating his nephew for his own ends, he is genuinely just as fond of Petrie as Petrie is of him, and seems to be the closest thing Petrie has to a father figure in the series.
- Never My Fault: His Fatal Flaw. Though as much of an egomaniac he is, it's Played for Drama as it has more to do with his guilt and agony for the raptor massacre he unintentionally led his followers to. He finally manages to overcome it at the end of the movie when he agrees to take responsibility for his actions, no matter how horrible the situation is.
- Obliviously Evil: Throughout the film, Pterano insists that he's a heroic figure and great leader to the herd, even when all the evidence around him says otherwise. Subverted in that he isn’t exactly “evil”, but still very much an antagonist.Pterano: People will think we're up to no good!
Rinkus: But we are up to no good.
Pterano: No! I work for the greater good! My purpose is noble! - Papa Wolf: When Rinkus slaps his nephew Petrie away while the latter is giving chase and trying to rescue Ducky, Pterano retaliates in kind.Pterano: [strikes Rinkus] If there's one thing I will not tolerate, it's violence!
Rinkus: Then why are you hitting me?
Pterano: Right, make that two things: violence and stupid questions! [strikes Rinkus again] - Pragmatic Villainy: Played with, as he does genuinely mean no harm to the kids, but he does still point out that doing so would also be inconvenient to his plan.Rinkus: Then why not simply make the longneck tell us where it [the stone of cold fire] is! (makes a slashing motion over his neck) Or else! (Evil Laugh before being smacked in the face by Pterano)Pterano: Mr. Rinkus, if you threaten the young ones it will put the elders on alert. They will watch our every move and our cause will be lost! Now is THAT what you want!?Rinkus: N-n-n-n-no! Of course not!
- Pride: He has a very overinflated opinion of his leadership abilities.
- Villain Song: 'Very Important Creature', another contender for the best villain song of the series, mainly because rather than being about how nasty and vicious he is, this song is simply about how brave and strong he thinks he is, and how egotistical everyone else thinks he is.
- Well-Intentioned Extremist: He legitimately believes himself to be a good leader and thinks that everyone would be better off with him in charge.
- Wouldn't Hurt a Child: The line he draws is violence towards young dinosaurs. He was quite upset with Rinkus knocking Petrie out of the air, and also remorseful when he believed Ducky fell and died in a hole, and later saves Ducky when she falls off a cliff.
Sierra and Rinkus
Rinkus on the left, Sierra on the right
Appearances: VII
Species: Flyer (Cearadactylus and Rhamphorhynchus, respectively)
Sierra voiced by: Jim Cummings
Rinkus voiced by: Rob Paulsen
Two conniving pterosaurs that associate themselves with Petrie's uncle Pterano. However, they seem to have plans all their own...
- Beware the Silly Ones: Rinkus initially seems like a goofy idiot, but turns out to be even more dangerous than Sierra.
- Brains and Brawn: Rinkus is the brains and Sierra is the brawn.
- Dirty Coward: Subverted with Rinkus. He initially seems to fit the trope, but it's later revealed that it was just part of an act he put on to seem less competent and dangerous than he actually was.
- Evil Has a Bad Sense of Humor: After Ducky falls into a hole, Sierra makes a cruel quip that it must have been quite the drop, then chuckles to himself.
- Faux Affably Evil: While Rinkus initially presents himself as something of a Punch-Clock Villain who only reluctantly goes along with the more forceful Pterano and Sierra, he's actually a ruthless and at times even cruel schemer willing to sink to depths Pterano is horrified by.
- Foil: Rinkus and Sierra are this to each other in terms of appearance, behavior, and how they handle their abhorrence for Pterano. Sierra is slender, has a more husky voice with a noticeable western accent, and makes little to no effort to hide how much of an asshole he is or how little he respects Pterano and his position as the leader of their group, being more than willing to kill him when his patience for Pterano's haughty nature runs out. Rinkus, on the other hand, appears much more rotund, has a higher-pitched voice with a Cockney accent, and puts on the facade of a submissive, cowardly toady to Pterano who is easily browbeaten into falling in line to hide how much he despises Pterano as much as Sierra, but is willing to refrain from killing their leader and deal with his arrogance long enough for Pterano to lead them to the stone so they can stab him in the back then.
- Foreshadowing: Rinkus' darker side is hinted at several times in the movie, like not so subtly implying that he wanted to threaten Littlefoot with violence or even death if he doesn't tell them the location of the stone.
- Gender-Blender Name: Sierra has a feminine-sounding name, but he is a male Cearadactylus.
- Hate Sink: Both of them, although Sierra more blatantly due to his snide, thuggish Jerkassery.
- Knight of Cerebus: They're much more threatening and less comical than Ichy, Dil and even Ozzy.
- Lack of Empathy: Both, so very much. When Pterano is worried that he might have caused Ducky's death, not only do they not care, but Sierra goes as far as to remind him of his disastrous attempt at being a herd leader.
- Laughably Evil: Subverted. Despite Rinkus's goofy behavior at first sight, nothing about them is Played for Laughs.
- A Lizard Named "Liz": Likely comes from phonetic respellings of Cearadactylus and Rhamphorhynchus, their genus names.
- Murder Is the Best Solution:
- Sierra suggests feeding the main characters to sharpteeth.
- Rinkus says that they should kill Littlefoot if he doesn't give them information about the stone.
- Not-So-Harmless Villain: Rinkus, who proves himself to be a pretty nasty schemer on several occasions and by the end of the movie is shown to be as much of a physical thug as Sierra.
- Not-So-Well-Intentioned Extremist: Unlike Pterano, they plot to use the titular MacGuffin for themselves.
- Obfuscating Stupidity: Underneath his supposed stupidity, Rinkus is easily the smarter and more treacherous of the two.
- Pragmatic Villainy: Rinkus, as opposed to the eccentric Pterano and just malevolent Sierra. His boss pisses him off and mistreats him? Goes perfectly in alignment with his will until muscle back up (in that case, his belligerent colleague) is conveniently available. Of course, he also points out to Sierra that it would be inconvenient for them to just kill Pterano and instead opts to just tolerate him long enough to get power from the Stone of Cold Fire, then dispose of him when he's no longer needed.Rinkus: Just be patient; let HIM lead US to the stone...
- Shout-Out: Rinkus is constantly twisting his tail in his hands, kind of like a certain other character. Not that he has anything in common with said character, though…
- Smug Snakes: Both of them, but Rinkus moreso than Sierra.
- The Sociopath: They're both this, in different flavors; Sierra's the violent, hateful sociopath with no empathy, while Rinkus is the lying, deceitful sociopath who can convincingly fake emotions and manipulate people. Although once he finally lets the mask slip at the end, Rinkus is arguably even more crazed and violent.Sierra: C'mon, you stupid slab! Show me the power!Rinkus: No! ME! SHOW IT TO MEEEEEEEE!
- The Starscream: They plot to put up with Pterano's self-aggrandizing ego long enough until he takes them to to the Stone of Cold Fire, where they try to take its supposed power for themselves.
- Vile Villain, Saccharine Show: They are quite unnerving for a cute movie about dinosaurs...
- Would Hurt a Child: Unlike their leader Pterano, Rinkus and Sierra have no problems with hurting kids. Rinkus slapped Petrie out of the air when he tried to get Ducky back, Sierra says he wants to feed the main characters to sharpteeth, and they both show absolutely no concern about Ducky possibly dying by falling in a hole, and also both talk about possibly killing the main characters to make their quest for the stone easier.
Rainbow Faces
Appearances: VII
Species: Rainbow Face (Gallimimus)note
Rainbow Face #1 voiced by: Charles Kimbrough
Rainbow Face #2 voiced by: Patti Deutsch (speaking) | B. J. Ward (singing)
A mysterious male and female Gallimimus who talk in riddles and seem to posses uncommonly advanced knowledge about the world. Their current whereabouts (if they're even still on Earth) are unknown.
- Alien Among Us: Never directly addressed, but very, VERY heavily implied, both by their more-than-saurian knowledge of how the world works, and by the shimmering pillar of light that marks their departure.
- Alien Non-Interference Clause: Their advanced alien race apparently forbids "telling" and "helping".
- Character Catchphrase: "That would be telling, wouldn't it?" usually said in response to the kids asking a question whose answer would reveal too much. In all fairness to the Rainbow Faces, the male one has his Saying Too Much problem.
- Cloudcuckoolander: The Great Valley seems to see them as weirdos who say bizarre things, although an Ankylosaurus, who is one of the visiting farwalkers, claims they seem 'harmless enough'.
- Deadpan Snarker: The female Rainbow Face.
- Like an Old Married Couple: How they generally act. And they might be one, but there's no confirmation.
- The Philosopher: They both bring up points of view that seem alien to the members of the Great Valley, such as the idea that there's nothing that makes the Mysterious Beyond 'mysterious' other than a lack of will to explore it.
- Saying Too Much: A running gag with the male Rainbow Face, something his companion likes to point out.Female Rainbow Face: Life is full of little mysteries, isn't it? (turns to the male one) And you are giving away far too many of them!
- The Spock: Both are incredibly logical and scientific about the world, and utterly unconcerned with how weird the Great Valley residents think they are.
Fast Biters Pack
Appearances: VII
Species: Fast Biter (Deinonychus)
A pack of Deinonychus that appear during a flashback in the seventh movie. They attacked Pterano's herd some time ago, with Pterano himself being the only one to escape with his life.
- Artistic License – Paleontology: Aside from their lack of feathers, they notably have only two fingers rather than three.
- Early Installment Character-Design Difference: Their appearance and colors are very different from the Deinonychus of the following movies and the animated series.
- Knight of Cerebus: They might be the deadliest Sharpteeth in the whole movie series, having caused the deaths of Pterano's entire herd.
- Raptor Attack: They are the first Deinonychus to ever appear in the franchise.
- Small Role, Big Impact: They only show up briefly during a flashback, but the fact that they've slaughtered Pterano's herd is something that still affects him to this day.
Debuted in The Land Before Time VIII: The Big Freeze
Mr. Thicknose
Appearances: VIII | several TV episodes
Species: Thicknose (Pachyrhinosaurus)
Voiced by: Robert Guillaume (VIII) | Dorian Harewood (TV series)
An old teacher who's responsible for giving young dinosaurs in the Great Valley their primary education. He lives alone in the Great Valley; it is unknown if he continues to teach or not.
- Ascended Extra: Appears in only one film, becomes a regular character in the TV series.
- Break the Haughty: Starts out the film as being very proud of his knowledge and position in the valley, and speaks to Grandpa scathingly about Littlefoot's stream of questions. When he's proven incredibly wrong about the potential of snowfall in the Great Valley, he's shunned by the herd and is forced to accompany the children on their journey to find Ducky and Spike.
- Cool Old Guy: After mellowing out by the end of The Big Freeze he becomes one in the TV show.
- Friendless Background: According to himself he was cripplingly shy as a youngster.
- I Just Want to Be Special: When he was young, Mr. Thicknose was incredibly shy and had difficulty making friends. He often spent his time listening to the things that the farwalkers had to say as they passed through the Great Valley, and it was because of this that he amassed so much second-hand knowledge. His position as a keeper of wisdom in the valley is so precious to him that when he loses it he feels as though he has little else to live for.
- Know-Nothing Know-It-All: Originally respected as the smartest resident of the Great Valley, having "Been everywhere and seen everything", it is then revealed that he gets most of his knowledge from second-hand sources. Though he does put the information he's gained about landmarks to good use later on.
- Spock Speak: Played for Laughs as he explains the various ways of getting leaves to fall from a tree, like the 'Cranio-Impactus Method' that involves hitting the tree with your head.
- Stern Teacher: He dislikes all of the prying questions Littlefoot keeps asking him, to the point that he tells his grandparents that he's a trouble-making influence on the rest of his class. Later, it's revealed he actually thought Littlefoot asked very good questions, but he had been afraid that it might have accidentally revealed that he really hadn't been everywhere and seen everything.
- Wise Old Folk Façade: Downplayed. Although he is not evil, he does pass himself off as an old mentor just so he can get some attention. When snow falls down on the Great Valley and Little Foot reveals that he had told Mr. Thicknose before it happened and that Mr. Thicknose refused to believe him, everybody becomes aware of his lies. He does redeem himself in the end with even Littlefoot referring to him as the oldest and wisest.
- Younger and Hipper: The TV show has Mr. Thicknose with a significantly deeper, younger sounding voice, along with a more energetic personality. He also seems to have become far more open in his beliefs: while he refused to accept that snow could ever fall in the great valley in film eight, he seems perfectly willing to believe that there is such thing as an invisible dinosaur in the TV series.
Tippy
Appearances: VIII | TV episode "The Forbidden Friendship"
Species: Spiketail (Stegosaurus)
Voiced by: Jeremy Suarez (VIII) | Cree Summer (TV series)
A young Spiketail who quickly becomes friends with Spike when his herd travels to the valley in search of food and shelter.
- Dude Looks Like a Lady: His high-pitched voice, prominent eyelashes, and peach-colored scales make him look rather feminine-looking despite being male.
- Forbidden Friendship: He’s extremely fond of Spike, and the two of them continue to play together in secret after their parents expressly forbid them from interacting with each other in the TV series.
- Innocently Insensitive: He commits acts of affection with Spike while unaware of how upsetting Ducky finds their bond.
- Keet: Excitable and energetic, he loves playing rough and tumble games with Spike.
- Third-Person Person: He talks like this.
Mountain Sharptooth
Appearances: VIII
Species: Sharptooth (Albertosaurus)
An Albertosaurus who chases the protagonists during the eighth film.
- Big Bad: He's the main Sharptooth antagonist of the eighth film.
- Disney Villain Death: Mr. Thicknose throws him a log which causes him to fall from a cliff.
- Human Snowball: While he's obviously not human, Littlefoot and his friends throw him a huge snowball that drags him down to the bottom of the mountain.
- Super Drowning Skills: During the opening scene, he tries to chase a hadrosaur in a pool of water, but he finds himself unable to swim.
- Uncertain Doom: It's unknown wether or not he survived his fall from a cliff, especially since other Sharpteeth, like the original Sharptooth or the Saurus Rock Sharptooth, survived similar falls.
Debuted in The Land Before Time IX: Journey to Big Water
Mo
Appearances: IX | X (cameo) | XII (cameo) | TV episode "The Missing Fastwater Adventure"
Species: Swimmer (Ophthalmosaurus)
Voiced by: Rob Paulsen
An energetic Opthalmosaurus who befriends Littlefoot after he becomes trapped in the floodwaters of the Great Valley. He lives in the Big Water with the rest of his family.
- The Cameo: He makes a brief apperance on screen during 'Adventuring' in Great Longneck Migration and 'Flip, Flap, Fly' in Great Day of the Fliers.
- Disney Death: Narrowly escapes a swimming sharptooth when it changes direction while he hides in a hollow log.
- Guest-Star Party Member: Journey to Big Water revolves around the gang trying to guide Mo through the flooded waterways around the Great Valley and back to the rest of his pod in the ocean.
- Innocently Insensitive: He can irritate Cera with his pranks and once pretended to get stuck underwater as a practical joke to Littlefoot and the others. He doesn't do it out of malice but under the impression it's good-natured fun.
- Keet: The little guy has tons of energy.
- Meaningful Name: Likely comes from Opthalmosaurus, which is his genus name.
- Starfish Alien: If the Swimming Sharptooth is an Eldritch Abomination from the kids' POV, then Mo is definitely one of these to them; a lot of attention is drawn to the fact that he's very different from them, although their differences are not treated as bad and it's made very clear that the only real way they're different is in physical appearance.
- The Prankster: He loves playing practical jokes on his mud brothers, the most common of which is suddenly spraying them with water or mud.
- Third-Person Person: Overlaps with You No Take Candle. "Mo come from BEEEG water!"
Sharptooth Swimmer
Appearances: IX
Species: Sharptooth Swimmer (Liopleurodon)
A voracious carnivore from the sea, this swimming sharptooth is a long way from home to be sure, but he won't let that get in the way of a good meal.
- Big Bad: Of Journey to Big Water.
- Evil Counterpart: To Mo. Both are non-dinosaurian reptiles from the ocean that are forcible taken from their homes and left in a newly made lake in the Great Valley. Unlike Mo, this one is a vicious carnivore.
- Eldritch Abomination: To the kids. They've never seen anything like it, and Littlefoot even calls it a monster.
- Kraken and Leviathan: Of the leviathan type.
- Never Smile at a Crocodile: Not quite, but it's certainly meant to bring this trope to mind
- Non-Malicious Monster: The only reason it ever crosses paths with the heroes is because it's trapped in the Great Valley with Mo. It is a carnivore, so it does try to eat the kids, but it's clear that it is just trying to get home, and it stops antagonizing them when it smells the ocean after a pathway to it is opened.
- Non-Standard Character Design: It's probably the most realistically designed creature in the series. Even the more vicious portrayals of sharpteeth in the series has them looking stylized and slightly cartoony, whereas the Sharptooth Swimmer looks like it was plucked straight out of a nature documentary. It also has no pupils or facial expressions (most of the time)
- Sea Monster: Well, it is a Liopleurodon, so what did you expect? It to be eating cheese?
Longneck Mom
Appearances: IX
Species: Longneck (Diplodocus)
Voiced by: Miriam Flynn
A nesting mother Diplodocus the children meet on the way to Big Water. Though initially presented as a threat for some strange reason, she quickly realizes that the gang of five are no threat to her eggs and allows them to take shelter with her for the night.
Debuted in The Land Before Time X: The Great Longneck Migration
Bron
"Your mother and I knew we were going to have a hatchling."
Appearances: X | TV episode "The Big Longneck Test" | XIV
Species: Longneck (Apatosaurus)
Voiced by: Kiefer Sutherland (X) | Cam Clarke (TV series) | Scott Whyte (XIV)
A herd leader that partakes in the Great Longneck migration. He's Littlefoot's long lost father, and the adopted father of Shorty. Due to the responsibilities of being a herd leader, he does not live in the Great Valley with his biological son, but now steers his entire herd to the valley at least once every year just to see him.
- Call-Back: Bron’s explanation of where he’s been for all of Littlefoot’s life provides more callbacks to the original film than at any other point in the sequels (the only other ones being a mention of the earthquake in the seventh film, mentions of Littfoot's mother dying in the fifth and fourteenth films, and some throwaway callbacks in the second, thirteenth, and fourteenth films). Among them is the only ever direct mention of the original Sharptooth to date.
- Daddy Had a Good Reason for Abandoning You: While at first Littlefoot didn't want to hear it and just lashed out at him asking where the hell he'd been all this time, Bron eventually provided an explanation he accepted. He'd left before Littlefoot was born to find a safe place for his family to live. When he returned after the earthquake, his wife was dead and his son was gone, making Bron assume Littlefoot was dead too, or at the very least so beyond his reach he'd never find him. He wandered around purposeless until he started gathering other longnecks together and ended up becoming the herd leader almost by accident. He was shocked to discover his son was alive and well in the care of his in-laws.
- Disappeared Dad: He left to find a suitable place to live before Littlefoot's birth and by the time he returned, a great earthquake had occurred.
- Distressed Dude: In Journey of the Brave, Bron gets trapped by lava while trying to save Wild Arms from his own clumsiness during an eruption at Fire Mountain. The events of the film revolve around Littlefoot setting out on a mission to find his father and rescue him.
- Easily Forgiven: Averted, big time. Bron ends up having to explain, in detail, where he’s been for the last nine films and why he’s never been a part of Littlefoot’s life for Littlefoot to forgive him.
- Good Parents: When he does reunite with Littlefoot and makes amends with him, he is shown to be a very loving father to both him and Shorty.
- I Thought You Were Dead: Bron's excuse for having never met his son until now.
- Lightning Bruiser: The only Longneck in the series to use a running start to attack a Sharptooth. Also the only one to not be defenseless when knocked off his feet—he just kicks the offending Sharptooth in the face and sends it rolling down a mountain.
- Like Father, Like Son: Looks remarkably like his son, such as having the same coloration. He's also a herd leader, much like Littlefoot who often acts like a herd leader to his friends during adventures. Oh, and there's also the fact that they both fought Sharpteeth and won.
- Magnetic Hero: After taking Shorty and other longneck children under his wing, other longnecks found themselves naturally gravitating towards him, until they eventually become an entire herd under his leadership.
- Meaningful Name: Likely comes from Brontosaurus, a genus commonly mistaken for Apatosaurus and, at the time the film was produced, assumed to be synonomous with Apatosaurus.
- Named Like My Name: When he was younger, people used to give him the nickname 'little foot'. His wife knew this about him, and decided to name their son after this.
- No One Gets Left Behind: Bron would risk his life for anyone in his herd— even for weirdos like Wild Arms.
- One-Hit KO: When he kicked a Sharptooth in the face in X, it went rolling down the mountain and didn't get up for about a minute. Which is a very long time, where Sharpteeth are concerned.
- Papa Wolf: Make no mistake, threaten Littlefoot, Shorty, or any of his herd, and he will end you, as various Sharpteeth learn the hard way.
- Parental Substitute: To Shorty.
- Remember the New Guy?: He somehow already knows who Chomper and Ruby are in the TV series, despite it never being shown how they were introduced, or how Bron reacted when he found out that one of his son’s best friends is the same kind of creature that killed his wife.
- Revision: The original film never addresses Bron's whereabouts, but the novelization reveals that Littlefoot's herd was much larger before Sharptooth picked them off; the unspoken implication is that this was the fate of Littlefoot's father. The tenth movie reveals that Bron was simply elsewhere until the Great Earthshake.
- Starting a New Life: The events of the first film more or less completely destroyed Bron's old life, as it left his wife dead, his old home in ruins, and the whereabouts of his child unknown. While trying to find some sign of the child that had been born while he was looking for a place for his family to live, he runs across Shorty, which leads him on a path to a new life as a herd leader.
Shorty
Appearances: X | TV episode "The Big Longneck Test"
Species: Longneck (Brachiosaurus)
Voiced by: Brandon Michael de Paul (X) | Elizabeth Daily (TV series)
An orphaned, troubled young Brachiosaurus who travels with Bron's herd. Bron later officially adopts him, making him Littlefoot's adopted brother. He lives a nomadic life with his adopted father.
- Big Brother Bully: When he first meets Littlefoot, his future step-brother, he picks on him. This tendency abates once Bron agrees to adopt Shorty.
- Brats with Slingshots: He uses his tail to smack pebbles at things with great precision.
- Calling Parents by Their Name: Even after Bron officially adopts him and becomes his father, Shorty still continues to call him Bron, and when talking to Littlefoot refers to him as 'your dad'.
- Green-Eyed Monster: Shorty is blisteringly jealous of Littlefoot hogging all of Bron's attention, to the point that he tries to start physical confrontations with him.
- Happily Adopted: By Bron.
- Leader Wannabe: While Littlefoot is off taking the big longneck test, Shorty takes his friends on an adventure in his stead. It quickly becomes apparent that he has none of his foster brother's leadership talents.
- No Place for Me There: While Bron is understandably ecstatic to have found the son he’d thought he’d lost long ago, Shorty sees it as Bron finding his ‘family’ and no longer having need for him, just like how his old companions left him when they found their own families after the events of the original film. Shorty prepares to slip away when Bron isn’t noticing, but Littlefoot stops him and tells him that Bron still cares for him, even bringing up the possibility of the two being brothers now.
- Street Urchin: Not unlike Littlefoot himself, Shorty was left alone to fend for himself after the Great Earthshake of the first film. However, unlike Littlefoot, Shorty never reunited with anything he could call family.
- What Happened to the Mouse?: Is neither seen nor mentioned in Journey of the Brave, despite the plot revolving entirely around finding Bron and the arrival of his herd.
Pat
Appearances: X
Species: Longneck (Apatosaurus)
Voiced by: James Garner
A friendly old longneck who helps Littlefoot's friends.
- Agony of the Feet: The poor guy gets his foot burned by lava.
- Cool Old Guy: He himself notes he is "not as young as [he] used to be", yet gets along well with the gang and protects and accompanies them on their journey to follow Littlefoot.
- Handicapped Badass: Despite suffering a severe burn to his foot by lava, forcing him to hobble with instability for the rest of the movie, he still manages to hold his own against the Sharpteeth.
- Meaningful Name: Likely comes from Apatosaurus, his genus.
- Nice Guy: Very genial and kind to the gang, and voluntarily protects them throughout their journey.
- What Happened to the Mouse?: He hasn't reappeared since the tenth film, despite deciding to come to the Great Valley with the others.
Sue
Appearances: X
Species: Longneck (Supersaurus)
Voiced by: Bernadette Peters
- Big Damn Hero: She's introduced saving Littlefoot from a hungry Sarcosuchus.
- Giant Foot of Stomping: The first thing we see of Sue is her enormous foot, which she uses to step on a Belly Dragger. She even points out that her big feet are quite useful to step on bad guys.
- Meaningful Name: The first two letters of her name Sue are the same as her species', Supersaurus.
- Statuesque Stunner: She is gigantic even by longneck standards on account of being a Supersaurus and is very attractive. Like most women, she prefers taller men, and is instantly smitten when the Great Longneck Migration puts her into contact with a male Ultrasaurus.
Sharpteeth Trio
Appearances: X
Species: Sharpteeth (Tyrannosaurus rex)
A trio of Tyrannosaurus who act as the main antagonists of the tenth film.
- Amazing Technicolor Wildlife: While most of the Tyrannosaurus rex of the movie series are green, one member of the trio is grey, and another is orange-brown.
- Big Bad Duumvirate: Or rather Big Bad Triumvirate in their case, but they collectively serve as the main antagonists of the tenth movie.
- Early-Bird Cameo: Possibly. An orange-brown Sharptooth appears briefly during the opening narration of the movie, which may or may not be the same one as the member of the trio.
- Screw This, I'm Outta Here: When the eclipse starts, they give up their pursuit of Bron, the other longnecks, and Littlefoot's friends, and flee.
- Terrible Trio: While the grey one and the orange-brown one initially acted on their own, during the climax the three Sharpteeth join forces and attack the longnecks as a trio.
- That's No Moon: When Cera, Petrie, Ducky and Spike finds the Grey Sharptooth asleep in the swamp, they mistake him for a huge boulder.
- Throw the Mook at Them: After Cera and Shorty made him trip, the Grey Sharptooth falls on the Orange-Brown Sharptooth, knocking them both down to the bottom of the hill.
- Use Your Head: The Orange-Brown Sharpteeth gives a headbutt to Pat, knocking him over.
Belly Dragger
Appearances: X
Species: Belly Dragger (Sarcosuchus)
A Sarcosuchus that lives in the swamp known as "Icky Gooey Place" by the protagonists. He serves as the secondary antagonist of the tenth film.
- Butt-Monkey: First he gets stepped on by Sue and almost drowns, then he has to listen to the children's annoying conversations, then Petrie hits his head, and finally Cera causes a tree to fall on him.
- Help, I'm Stuck!: Last time we see him, he's trapped under a rotten tree, though Ducky doesn't think it will hold him forever.
- Never Smile at a Crocodile: He seems to be a Sarcosuchus, one of the largest prehistoric crocodilians.
- Rage Breaking Point: When the children come to the swamp, he pretends to be a rock and waits for them to jump on him to eat them. However, they spend so much time arguing about which rock they should jump on next that he finally loses patience and attacks them straight away.
- That's No Moon: Exploited. He pretends to be a floating log or a rock so that young dinos will try to jump on him and get eaten.
- Yellow Eyes of Sneakiness: He has yellow sclerae and is a devious predator that uses deception to lure his prey.
Debuted in The Land Before Time XI: Invasion of the Tinysauruses
The Tinysauruses
Appearances: XI | XII (cameo)
Species: Little Longneck (Mussaurus)
Big Daddy voiced by: Michael Clarke Duncan
Lizzie voiced by: Cree Summer
Other voices: Leigh Kelly (Skitter) | Ashley Rose (Dusty) | Nika Futterman (Rocky)
A group of friendly but oft-persecuted tiny dinosaurs that are searching for a place to live. After a lengthy fiasco involving a fruit tree, they eventually elected to make the Great Valley their new home.
- Authority Sounds Deep: The leader of the tinysauruses, Big Daddy, is voiced by Michael Clarke Duncan.
- Beneath the Earth: They initially hide in the caves underneath the Great Valley to avoid persecution from larger dinosaurs. According to Ducky in Stranger from the Mysterious Above they still live in the valley caves by the time of the TV series, despite not having any reason to hide anymore.
- Call a Rabbit a "Smeerp": Despite it being in the title of the eleventh movie and the term they’re most widely know by, they’re never actually called ‘Tinysauruses’ in the film, and instead called ‘little longnecks’. However, in an episode of the TV series Ducky does refer to them as such.
- The Cameo: Several Tinysauruses briefly appear during a subterranean sequence in the song 'Flip, Flap, Fly' in Great Day of the Fliers.
- Informed Species: While Mussaurus were sauropodomorphs and an early relative to proper sauropods, they weren't actual sauropods themselves and had a body structure that differed in many ways from the typical sauropod body shape they're shown having in this film, most notably the fact that they were believed to be capable of bipedal locomotion as adults.
- Lantern Jaw of Justice: Big Daddy has a very prominent chin.
- Little People: They're the smallest dinosaurs in the series, with the adults being even smaller than Ducky. Justified, as juvenile Mussaurus were indeed incredibly tiny (hence the name 'Mouse Lizard'), although in real life the adults got much bigger than how they're depicted here.
- The Scapegoat: Littlefoot blames them for eating all the tree sweets off a special tree, which is half-true but ignoring how they couldn’t have done so without him accidentally knocking them all down. Partly because of his own initial fear of them, Littlefoot doesn’t realize how much trouble this causes for the tinysauruses until he gets to know some of them personally. As it turns out, getting unfairly blamed for misfortunes is something that happens to them wherever they go.
- Science Marches On: Since their discovery in the 1970s, Mussaurus were only known by juvenile specimens and their size shown in Invasion of the Tinysauruses wasn't inaccurate with what was known at the time. A few years later, however, adult Mussaurus fossils were found and were significantly larger than the juvenile specimens that gave the genus its name, making the film’s depiction of them inaccurate in hindsight.
- Vocal Dissonance: Big Daddy is a tiny dinosaur with a deep, booming voice provided by Michael Clarke Duncan.
- Walking the Earth: Everywhere they go they’re treated like vermin, and travel from place to place to try to find somewhere they can call home. At first it seems as though the Great Valley is just as prejudiced towards them as anywhere else, but by the end of the film they elect to settle and become valley residents.
Tria
Appearances: XI | XII | XIII | several TV episodes
Species: Three-horn (Triceratops)
Voiced by: Camryn Manheim (XI and XII) | Jessica Gee-George (XIII and TV series)
A pink Triceratops who had courted Cera's father when they were young. She marries Topsy, becoming Cera's stepmother, and later gives birth to Cera's half-sister, Tricia. She lives in the Great Valley with her husband, daughter and stepdaughter.
- Brooding Boy, Gentle Girl: The gentle girl to Topsy's brooding boy.
- Death Glare: Gives an absolutely livid one to Mr. Threehorn when she realizes he played a big part in making the Tinysauruses seem far more dangerous than they actually were to the rest of the valley and nearly getting them killed in the process.
- Good Parents: She's a good parent to her biological daughter and a good stepparent to her stepdaughter.
- Mama Bear: In the final act of Invasion of the Tinysauruses she aggressively defends Cera from a group of fast biters, despite the two having being on rocky terms with each other for most of the film.
- Minnesota Nice: In the TV series, at least. There are hints of the accent in her inflections, and she certainly has the polite behavior.
- Morality Pet: She seems to be the only adult in the series capable of soothing Cera's hot-headed father.
- New Old Flame: To Topsy.
- Nice Girl: She's a total sweetheart, even when Cera is a jerk to her.
- Open-Minded Parent: Unlike Topsy, Tria never displays any speciesist tendencies and is nothing but polite and welcoming to Cera's non-threehorn friends, even to Chomper who her husband has displayed a regular fondness for tormenting.
- Pregnancy Makes You Crazy: She's no longer gravid by the time we meet Tricia's egg, but she's nonetheless very moody and emotional.
- Wicked Stepmother: Inverted. When she first gets together with Topsy, she takes great pains to try to establish a healthy, loving relationship with Cera, who's unwilling to facilitate it at first. Tria's patience eventually runs low and the two clash briefly (with Tria still maintaining a calm, reasonable demeanor), but Cera decides to give her a chance. After that, she loves and cares for Cera like she's her own daughter.
Fast Biters Duo
Appearances: XI
Species: Fast Biter (Deinonychus)
A pair of Deinonychus that managed to get into the Great Valley during the eleventh film.
- Artistic License – Paleontology: Like most Deinonychus in the franchise, they lack feathers and only have two fingers instead of three.
- Big Bad Duumvirate: While they only appear pretty late, they both are the main Sharpteeth antagonists of the eleventh film.
- Raptor Attack: They are a duo of vicious Deinonychus and, as mentioned above, they aren't entirely accurate.
- Red Eyes, Take Warning: Both of them are vicious predators with red sclerae.
- Screw This, I'm Outta Here: When all the adults arrive, they wisely decide to run away from the Great Valley.
- Tickle Torture: One of them is subjected to this by the little longnecks.
Debuted in The Land Before Time XII: The Great Day of the Flyers
Guido
Appearances: XII | TV episode "The Hermit of Black Rock''
Species: Glider (Microraptor gui)
Voiced by: Rob Paulsen
A nervous glider who becomes friends with Petrie. He suffers from amnesia for much of the twelfth film and believes he's the only one of his kind. By the end of the film, he elects to live in the Great Valley.
- Informed Species: Even by the standards of the series he is stylized as hell, resembling more or an odd Oviraptor-muppet than the thing he's supposed to be.
- Instant Expert: Has no problem flying, as long as he is asleep. Later learns to do it for himself.
- Joisey: He possesses a mild New Jersey accent.
- Last of His Kind: Allegedly, likely stemming from...
- Laser-Guided Amnesia: He wakes up in the Great Valley and has no idea where he is, what he is, where he came from, how he got here...
- No Celebrities Were Harmed: A pretty obvious Woody Allen parody.
- Noodle Incident: Chomper mentions that the two were first introduced when Guido baby sat for Tricia, which is why he's only nervous when he sees him instead of outright terrified.
- Remembered I Could Fly: See above, and only after everyone tells him he can.
- Plucky Comic Relief: Like Petrie, he's a panic-prone flier whose fears are often Played for Laughs.
- Science Marches On: Since the coloration of almost all dinosaurs is unknown, Guido’s teal feather colors were in the realm speculative artistic license by the time of film twelve, just like the colors of pretty much every other creature in the series. However, a few years after Great Day of the Flyers, new analytical techniques resulted in the discovery of what color Microraptor’s plumage actually was: glossy iridescent black, not teal.
- Toothy Bird: Inverted; Microraptors had toothy snouts in real life, but Guido has a toothless, parrot-like beak.
- Vegetarian Carnivore: Subverted. He doesn't know what kind of animal he is, so it takes a while for him to figure out his real diet. He starts out trying to eat leaves, but he's grossed out by them. He instead eats a bug that he found on one of those leaves... and he instantly loves it. His friends are kind of squicked out by this.
Tricia
Appearances: XII | several TV episodes
Species: Three-horn (Triceratops)
Voiced by: Nika Futterman (XII) | Meghan Strange (TV series)
A giggly young threehorn hatching. She's the youngest daughter of Topsy and Tria, as well as Cera's half sister. She was born and lives in the Great Valley with the rest of her family.
- Baby Talk: She is too young to talk, although she's already said her first word: 'Cera'.
- Big Sister Worship: Cera is the very first thing Tricia ever sees, and as such she takes an immediate liking to her big half-sister. In fact, she's so fond of Cera that she seems more willing to devote her attention to her than to their parents.
- Cheerful Child: She seems to take heavily after her mother's warm, sunny personality, and is rarely seen without a giggle or a smile.
- Fearless Infant: Not unlike her older nephew and niece Dana and Dinah, Tricia easily gets into danger and often needs her big sister or her parents to keep a close eye on her and bail her out of trouble.
- Ridiculously Cute Critter: Being a little Triceratops hatchling, how can she not be?
- Sibling Rivalry: Cera was none too keen of Tricia when she was first hatched, as she hogged all of her father's and Tria's attention. By the end of film twelve, however, Cera grew to love her new half-sister, and future installments almost always show them on good terms with each other.
- Sibling Yin-Yang: While Cera is grumpy, short-tempered, and aggressive like her father, Tricia is bubbly, exuberant, and playful like Tria.
Sailback Sharptooth
Appearances: XII
Species: Sailback Sharptooth (Spinosaurus)
A Spinosaurus who lives in the Mysterious Beyond and the main Sharptooth antagonist of the twelfth film.
- Artistic License – Paleontology: He has a lot of differences with the real animal, notably the fact that he has only two fingers instead of three.
- Big Bad: Of the twelfth film, by virtue of being the only antagonist to appear.
- Help, I'm Stuck!: The Sailback Sharptooth gets trapped between rocks while chasing the children. However, according to Littlefoot, this won't stop him for long.
- Phlegmings: He's a hungry predator that is constantly drooling.
- Savage Spinosaurs: A vicious Spinosaurus who tries several times to devour the heroes.
- Shout-Out: He looks and acts very similar to the Spinosaurus from Jurassic Park III, even the way he gets stuck is reminiscent of a scene in that movie.
- That's No Moon: At first, Guido crashes onto his back and thinks it's just a big rock. When he starts to move, he initially assumes it's an earthquake. Then he sees his head and jaws...
- Tickle Torture: Guido manages to get out of his mouth by tickling his palate with one of his feathers.
- Yellow Eyes of Sneakiness: He has yellow sclerae and is a ferocious predator.
Debuted in The Land Before Time XIII: The Wisdom of Friends
Loofah and Doofah
Appearances: XIII
Species: Yellow Belly (Beipiaosaurus)
Loofah voiced by: Cuba Gooding Jr.
Doofah voiced by: Sandra Oh
- Call a Rabbit a "Smeerp": They're referred to as "Yellow Bellies".
- Does This Remind You of Anything?: Doofah has a habit of calling Cera beautiful. That combined with picking her up the first time they meet, well...
- Escort Mission: They seem so naive, incompetent, and clumsy that Littlefoot actually feared for their safety when they mention they're traveling alone, to the point of having nightmares about them meeting some horrible fate. He decides it would be best if he and his friends tag along to keep an eye on them. This can also count as Adults Are Useless, or perhaps more aptly, Adults Are Helpless.
- Inexplicably Tailless: They do not have a tail but instead a ponytail of feathers.
- Informed Species: They don't bare very much resemblance to the real Beipiasaurus. They almost don't even look like actual dinosaurs!
Foobie
Appearances: XIII
Species: Yellow Belly (Beipiasaurus)
Voiced by: Pete Sepenuk
Loofah and Doofah's silent, often-overlooked, traveling companion.
- Odd Name Out: Foobie’s name does not rhyme with Loofah or Doofah.
- The Silent Bob: He’s a Yellow Belly of few words, yet most characters understand him just fine.
Sharptooth Pack
Appearances: XII
Species: unspecified Sharptooth (Baryonyx)
- Big Bad: Of Wisdom of Friends.
- Butt-Monkey: They're beaten up a lot throughout the movie. First they are buried under rocks, then one of them is hit by Cera's horn, another stumbles on a stone, and finally they all fall off a cliff.
- Disney Villain Death: In the end, the Yellow Bellies make them fall off a cliff.
- Good Scars, Evil Scars: The leader has a scar running down its face.
- Informed Species: They barely resemble Baryonyx, not even having the enlarged claw on their thumbs which the genus is named for!
- Savage Spinosaurs: They're a pack of Baryonyx, the second most well-known species of spinosaurids, and they are vicious antagonists.
Debuted in The Land Before Time XIV: Journey of the Brave
Wild Arms
Appearances: XIV
Species: unidentified (Nothronychus)
Voiced by: Damon Wayans Jr.
A loud, highly eccentric member of Bron's herd who's well known for getting himself into trouble and flailing his arms about. He travels with the rest of Bron's herd.
- Butt-Monkey: He's rarely shown in a dignified position.
- Cloudcuckoolander: He didn't even realize the origin of his name until he seemingly realized it in the middle of his conversation with Mr. Threehorn.
- Fainting: He's terrified of Chomper the moment he sees him, and as soon as the boy goes in to hold his hand to guide where he's going, he faints on the spot.
- The Fool: He seems sheepishly aware of how foolish he comes across to people, and simply can’t help that he annoys people, scares easily, and is a massive klutz. Even his attempts to try make himself look a bit more dignified end with him all but admitting that he knows he’s not fooling anyone.
- Guest-Star Party Member: Not for the gang, but for Mr. Threehorn and Grandpa Longneck as they trail Littlefoot.
- Hate at First Sight: A one sided version. Topsy dislikes him the moment he sets eyes on him. Wild Arms is intimidated by Mr. Threehorn, but does try to get into his good graces as the film goes on.
- The Klutz: He has, to put it mildly, a striking lack of grace, and often flails his arms around wildly when he's running about. It's this clumsiness that ends up putting Bron in danger as he stays behind to rescue him.
- Lovable Coward: He constantly suggests going back to the Great Valley instead of going to save Bron, and is so terrified of Chomper— a kid who's less than half his size— that he faints when he so much as touches him.
- Miles Gloriosus: He'll often retell stories in a way that paints him in a better light than how it actually happened, although absolutely no one is fooled by this.
- The Millstone: A light example: other than giving directions he’s often more work than he’s worth to the rescue group consisting of Grandpa Longneck, Mr. Threehorn, Chomper, and Ruby. However he doesn’t seem to slow them very much as even when he faints from Chomper touching his arm Mr. Threehorn simply lugs him over his shoulder and comments how he knew he’d end up having to carry him.
- Only Known by Their Nickname: 'Wild Arms' is a name that everyone has assigned him because of his wild, colorful arms, and as such it isn't his actual name. In fact, he didn't even realize what it was referring to until recently.
- Rhetorical Request Blunder: After running away from volcano eruption, he says "Am I really here? Somebody pinch me, please." When he sees that the nearest person is an unamused Mr. Threehorn glaring daggers at him, he quickly defies this trope—he just pinches himself.
- Sidekick Creature Nuisance: It's clear that the other adults find him very hard to put up with because of his loud, talkative, cowardly nature, which is especially true for Mr. Threehorn who's almost always seen glaring at him.
Etta
"When things get darkest, that's when you look for the light."note
Appearances: XIV
Species: Flyer (Pteranodon)
Voiced by: Reba McEntire
A flyer who's a member of Bron's herd, and is separated from everyone else by the eruption of fire mountain. She travels with the rest of Bron's herd.
- Analogy Backfire: Almost every uplifting metaphor that comes out of her mouth is followed by a down-beat aside that kills any hopeful effect she was going for.
- Animal Gender-Bender: She is tall and has a long crest like a male Pteranodon. Gets jarring in that the franchise already had Petrie's mother, who is an accurately-portrayed female Pteranodon.
- Call a Rabbit a "Smeerp": She's specified as a 'Big Beak' subtype of flyer.
- Cloudcuckoolander: Her way of thinking is odd to say the least. She also has the habit of telling morbid stories.
- Cool Old Lady: She's significantly older than the main cast, but still optimistic and hopeful. When Littlefoot is beating himself up over getting his friends into a situation too big for them to handle, she tries her best to cheer him up.
- Ink-Suit Actor: She has Reba McEntire's green eyes and long eyelashes, as well as a red tinge on her crest that's the same color as Reba's hair.
- Non-Standard Character Design: She looks completely different than the other Pteranodon in the series, not even bearing the slightest resemblance to Petrie.
- Rambling Old Man Monologue: She has plenty of stories about her family that she loves to bring up, and most of them end morbidly.
- Southern Belle: Etta retains her voice actress's pronounced southern drawl in the film.
- Suspiciously Similar Substitute: For Archie from film four, another old cave dweller who helped Littlefoot when he was separated from his friends because of a cave-in, and Swooper from the TV series, who’s also a cave dwelling old flier with a southern accent and a few screws loose.
- Team Mom: She's very affectionate towards Littlefoot in particular, which might be due to the fact that he's her herd leader's son.
Featherhead Sharpteeth
Appearances: XIV
Species: Featherhead Sharptooth (Yutyrannus)
A pair of sharpteeth who terrorize the gang during their search for Bron.
- Big Bad Duumvirate: Of the first half of the fourteenth film.
- Feathered Fiend: By virtue of being the largest known feathered carnivorous dinosaur.
- Four-Fingered Hands: Inverted; Yutyrannus has three fingers per hand, but these guys have four fingers.
- Non-Standard Character Design: Unlike the other sharpteeth, they have their antorbital fenestra faintly visible. Also a case of Artistic License – Paleontology as this is a process known as "shrink-wrapping".
- What Could Have Been: According to an interview with one of the film's animators, they were apparently planned to be Allosaurus at some point.
- What Happened to the Mouse?: Chomper, Ruby, Wild Arms, Grandpa Longneck, and Topps never encounter them as they pass through their territory (at least not on-screen).
Diggers
Appearances: XIV
Species: Digger (Oryctodromeus)
Voiced by: Rob Paulsen | Jeff Bennett | Anndi McAfee | Aria Curzon
A colony of small ornithopods which crowned Petrie as their leader when he retrieved fruit for them.
- Informed Species: They're extremely stylized even by the standards of the series and also much smaller than Oryctodromeus were capable of getting, being shown to be roughly the size of Petrie in Journey of the Brave when in reality they could grow up to two meters long and a little under a meter tall.
- Instant Fan Club: After Petrie unintentionally helps them retrieve some fruit from a tree they treat him like he's practically royalty. They're also shown to do this to pretty much anyone who helps them get food, as shown when they immediately crown someone else their new leader as Petrie is leaving just for accidentally knocking down a few pieces of fruit.
- You No Take Candle: They seem to only speak a very broken form of the leafeater language, possibly due to their implied omnivorous diet.
Horned Sharptooth
Appearances: XIV
Species: Horned Sharptooth (Carnotaurus)
The second main threat which Littlefoot's friends encounter in the Land of the Featherhead Sharpteeth.
- Artistic License – Paleontology: Both its horns and forelimbs are too long and facing forwards.
- Attention Deficit... Ooh, Shiny!: In his second scene, while suspicious that the rescue group of Grandpa Longneck, Mr. Threehorn, Chomper, Ruby, and Wildarms is in the area, he spots a herd of Ornithomimidae and chases them off, leaving the film.
- Big Bad: Of the second half of the fourteenth film.
- Darker and Edgier: Noticeably more vicious and relentless than the Featherhead Sharpteeth and without any moments of comedy to give it levity.
- Four-Fingered Hands: Carnotaurus actually did have four fingers, but the one here has only three. Although in some shots it is shown with the accurate four fingers.
- Non-Standard Character Design: Like the featherhead sharpteeth, it too has a shrink-wrapped skull.
- Stock Audio Clip: Many of his roars come from the audio of one of the bosses from the Lost World: Jurassic Park light gun arcade cabinet. Ironically, it uses the T. Rex's audio, even though a Carnotaurus boss exists in the game.
