The Gang of seven
A general list of tropes pertaining to the group of protagonists in the Land Before Time movies and TV series. They are: Littlefoot, Cera, Ducky, Petrie, Spike, Chomper, and Ruby.
- Amazing Technicolor Wild Life
- Berserk Button: Fuck with any of them and the others will be down on you like a very large and very heavy tonne of bricks.
- Big Damn Heroes:Littlefoot: "You came for me!"Cera: "Don't we always?"
- Brother-Sister Team: Ducky and Spike
- Call a Rabbit a "Smeerp": The kids are, respectively, a 'Longneck', a 'Threehorn', a 'Flier', a 'Swimmer', a 'Spiketail', a 'Sharptooth', and a 'Fast Runner'.
- Establishing Character Moment:
- A newly hatched Cera headbutts her way out of her egg.
- Ducky jumps around while she's barely out of the egg, follows an insect around, then peers curiously into the mouth of a snapping turtle.
- Petrie falls screaming from a tree, gets tossed around a bit, then excitedly asks if he flew.
- Spike eats his own nest.
- Fighting the Lancer: Littlefoot and Cera's fight in the first film.
- Fire-Forged Friends
- Five-Man Band: Formerly this, but gained two members in the TV show.
- Grief Song: 'Always There' (the final verse of which Littlefoot sings about his mother) from the fifth film is part grief song and part lullaby; along with 'Bestest Friends' from the tenth movie and 'If We Hold On Together' from the first movie, it's one of the best songs the long and musical series has ever produced.
- Group Hug: At several points, but most notably in the last shot of the first film.
- Headbutting Heroes: Littlefoot and Cera avert this in the usual sense (except in the first movie, where it's played straight, and very briefly in film five), but the trope holds true in the literal sense: at several points they've actually butted heads.
- Hero Recruitment Song: 'You're One of Us Now' from the second film. Definitely a Crowning Moment Of Heart Warming.
- Interspecies Friendship
- Kid Heroes: It's no question that all seven of them fit, but in terms of ages, it's never definitively stated. Ruby is assumed to be the eldest of the gang, while Cera claims to be the oldest of the original five. The order of Littlefoot's, Petrie's, and Ducky's births seems unclear. The only order that is definitely known is that Chomper is the youngest and Spike is the second youngest.
- Like Brother and Sister: Both Littlefoot and Ruby act like older siblings to Chomper.
- Masculine Girl, Feminine Boy: Littlefoot is soft spoken and polite. Cera is snarky and brash.
- Naughty Is Good: Rarely obey their parents' rules. Then again, considering not one of their parents rules has ever shown to help with anything, you can't exactly blame them.
- Nice Job Breaking It Heroes: Many of their adventures involves one or all of them screwing up in some way, and then rushing to fix their mistake.
- Odd Friendship: A soft spoken Apatosaurus, a hot headed Triceratops, a happy-go lucky Hadrosaur, a panicky Pteranodon, and a mute Stegosaurus somehow make a cohesive and tight-nit group. It gets even more bizarre when a friendly Tyrannosaurus and a whimsical Oviraptor get added to the crew.
- Pragmatic Hero: All of them; they're not adverse to fighting dirty when confronted with sharpteeth.
- Promoted To Parent: In the first sequel, the gang ends up having to raise the newly hatched Chomper until his real parents come to claim him.
- Rag Tag Bunch Of Misfits
- True Companions
- Unusual Animal Alliance
- Vitriolic Best Buds: Littlefoot and Cera.
- When I'm Gone Song: Inverted with 'Bestest Friends' from the tenth film (which is more of a 'When You're Gone' Song considering the context).
The Land Before Time (first film)
Littlefoot - Apatosaurus
A young male Apatosaurus born in the desolate lands east of the Great Valley. He's the main protagonist of the Land Before Time series. He lives in the Great Valley with his Grandparents and best friends.Appears in all thirteen films and the TV series.
- Badass: Dude once threw himself off a cliff to save Chomper without a second's hesitation. Now that's hardcore.
- Berserk Button: Don't insult his mother.
- Beware the Nice Ones: Qualifies as this in the first movie. After dealing with Cera's attitude for a while and then her remark about his mother being stupid, Littlefoot snaps at her to take it back, resulting in a fight.
- Big Brother Instinct: Towards Chomper and Ducky.
- Death Glare: Gives this to Cera in "The Great Day of the Flyers" when she seemed reluctant in rescuing Guido from the Mysterious Beyond.
- Disappeared Dad: Played straight until The Land Before Time X: The Great Longneck Migration.
- The Heart: Along with Ducky.
- The Hero
- Hero's Journey: At the beginning of the first movie, Littlefoot is a friendless, naïve child who's very much dependent on his mother to survive. By the end, he's become a strong, wise leader with more friends than he could have ever dreamed of.
- Heroic BSOD: After his mother dies, Littlefoot goes into a deeply depressed state. He refuses food when it's offered to him and seems to lose much of his will to find the Great Valley. The two things that snap him out of it is a chance encounter with the wise Rooter and running into another lost child like himself: Ducky.
- How Dare You Die on Me!: While talking with Rooter, Littlefoot tearfully says his mother should have known better than to fight the black sharptooth. This is likely just a statement out of intense grief, as her death leaves him completely alone in the world.
- It's Personal/You Killed My Mother: Not outright stated, but when the opportunity to kill Sharptooth appears, Littlefoot is the first to take it.
- Less so in the original ending - where he discovered the Great Valley and then went back to rescue the others - where it was more to prevent Sharptooth from following them into the Great Valley.
- The Leader: Classic Type II leadership.
- Nerves of Steel: If something's going wrong, Littlefoot's generally the one who keeps his head together.
- Nice Guy
- Only Sane Dinosaur: Usually. He does his fair share of unreasonable things as well.
- Raised by Grandparents: After Littlefoot's mom dies, his maternal grandparents assume guardianship of him.
- Red Is Heroic: His eyes are a shade of reddish brown that varies anywhere from mahogany to maroon between movies.
- Screw the Rules, I'm Doing What's Right: Frequently breaks the rules in order to fix a problem that the adults won't.
- Siblings Wanted:
- In the 9th film, Littlefoot laments that he has no brothers or sisters to play with. One movie later, he get's an adopted brother: Shorty.
- Chomper might technically be called his 'godbrother', considering he oversaw his birth.
- Mo and Littlefoot declare themselves 'Mud Brothers'.
- Street Urchin: The dour conditions of Littlefoot's first years of life are a clear metaphor for being born into poverty, and when he loses his mother, he perfectly fits the description of a desperate street orphan.
- Red Oni, Blue Oni: The calm, reasonable Blue to the hot-headed Cera's Red.
- Sympathy for the Devil: Given what the original sharptooth did to him, his friends, and his family, Littlefoot has plenty of reasons to fear and hate the newly hatched Chomper for what he is. However, he refuses to forsake a newborn child for what the rest of his kind has done, and is the most vocal proponent in the group to caring after him.
- Trademark Favorite Food: Mutha fuckin' treestars, bitch!
- Undying Loyalty
- What the Hell, Hero?: In Invasion of the Tinysauruses, Littlefoot accidentally knocks all of the fruit off of a special tree that no one is to eat from until everyone is there to share it. He proceeds to lay the blame on the innocent Tinysauruses, and the rest of the Valley inhabitants try to chase away and destroy the innocent micro-dinos. When Littlefoot admits he lied, everyone gives him a disbelieving reaction.
- Wise Beyond Their Years: Played fairly realistically. While he's still clearly a kid at heart and prone to making mistakes, his values, beliefs, and sense of duty are very advanced for his age.
- Would Hit a Girl: To be fair, the girl in question can shatter rocks with her head.
- You Imagined It: No one believes Littlefoot saw a mysterious blue stone fly over the Valley and land on Three Horn Peak in The Stone of Cold Fire. Except for two small dinosaurs that may or not be aliens in disguise.
Cera - Triceratops
A hot-headed female Triceratops. She's one of the main characters throughout the series. She lives in the Great Valley with her father, stepmother, and half sister.Appears in all thirteen films and the TV series.
- Action Girl: When you can shatter rocks with your head, you've earned this title.
- Big Sister Instinct: Towards her baby sister Tricia, as well as her friends.
- Break the Haughty: She spends most of the first film bragging about how she can take care of herself...until she nearly gets everyone killed following her way.
- Can't Live With Them, Can't Live Without Them: Despite constantly complaining about them, she seems to genuinely value her friends.
- Catch Phrase: In the TV series: "I'll believe it when I see it."
- Daddy's Girl: She is close to her father, which makes sense because of her mother's disappearance. Her relationship with him is part of the reason why she's so stubborn and tomboyish.
- Deadpan Snarker: A big one in the sequels and TV show. Provides a lot of the funnier lines in the series as a result.
- Fantastic Racism: Especially in the first film. She mellows pretty fast, though.
- Green-Eyed Monster: Cera seems to get extremely jealous when an outside character hogs all of Littlefoot's attention. This is most visible with Ali and Mo.
- Hair-Trigger Temper: It doesn't take much to anger Cera. But this is toned down greatly in the sequels... unless her friends or her baby sister are being threatened.
- Ineffectual Loner: In the first movie, before learning The Power of Friendship and becoming part of the group. In later movies she still has a tendency to storm off by herself after disagreements with the group, but her leave is never permanent.
- Jerk with a Heart of Gold: She's bossy, she's egotistical, she's short-tempered, and she'll always come through for her friends. Although in the first film she was bordering on Jerk Ass, only just redeeming her self in the final act.
- The Lancer
- Red Oni, Blue Oni: The Red to Littlefoot's Blue.
- Token Evil Teammate: In the first film. In some ways, she is actually more antagonistic than Sharptooth!
- Tomboy and Girly Girl: Tomboy to Ducky (and later Ruby's) Girly Girl.
- Ungrateful Bitch: For most of the first movie, she remains prejudiced against longnecks and goes so far as to call Littlefoot's mother stupid even after she'd given her life to save her and Littlefoot from Sharptooth. Like many other negative traits, this too fades out as time goes.
- Use Your Head: She is a Triceratops, after all.
- Welcome Back, Traitor: She's accepted as a friend after she helps to kill Sharptooth, even though she'd left Ducky, Petrie, and Spike to nearly die awhile back.
- Then again, Littlefoot was almost as bad, seeing as he used Ducky as bait for the Sharptooth.
- Why Did It Have To Be Heights: Cera doesn't do too well when it comes to cliffs, chasms, and anything involving crossing them. Unfortunately, they face this dilemma at least once a movie
Ducky - Parasaurolophus or Saurolophus
A cheerful female hadrosaur. She's one of the main characters throughout the series. She lives in the Great Valley with her mother and siblings.Appears in all thirteen films and the TV series.
- Catch Phrase: "Yep yep yep!"
- Cheerful Child
- The Chick
- Damsel in Distress: Frequently fits this role.
- Disappeared Dad: Her father appears in the first installment but vanishes in the sequels. Granted, this might be due to what happened to Judith Barsi at the hands of her father...
- Fly On The Wall: Her smalls size means she often walks in on important conversations unnoticed. See Spanner in the Works.
- The Heart: Along with Littlefoot.
- Jerkass Façade: In movie eight, Ducky attempts to pretend that she doesn't care about Spike when he starts giving his new friend Tippy more attention than her. In one scene, where Petrie casually mentions Tippy's herd is going away, the facade instantly breaks and she joyfully hugs a very confused looking Petrie.
- Nervous Humming: While trying to muster up the nerve to call Sharptooth's attention to her, she hums nervously under her breath.
- Nice Girl
- Motor Mouth: A mild example in the first movie, mostly due to her many verbal tics and outgoing personality, which goes along with the original name for 'swimmer': Bigmouth.
- Platonic Life Partners: With Petrie
- Spanner in the Works: It's quite amazing how such a little girl can cause so many problems for so many different villains. It's also the primary cause for her Damsel in Distress role.
- Team Mom: She always comforts and pep-talks everyone, and her plucky personality usually rubs off on everyone around her.
- Tin Man: In The Big Freeze, Ducky had to ask Cera what the strange emotions she was feeling towards Spike's constant snoring and keeping her awake were. When Cera told her she was feeling angry, Ducky was mystified, because she had never felt anger before, and Cera has to teach her (In song, no less), how to express anger.
- This is probably referring to explicit anger, as she's clearly shown to display annoyance and dislike before this.
- Tomboy and Girly Girl: Girly Girl to Cera's Tomboy, although she's pretty adventurous and is only really a Girly Girl when compared to Cera.
- Verbal Tic: Ducky has several. The first and most widely known is her tendency to repeat yes or no three times at the end of a sentence for emphatic effect. She does the same for 'he/she/it does' and 'he/she/it is', except she only repeats these phrases twice at the end of a sentence. Finally, she'll occasionally add needless tense modifiers at the end of words, resulting in phrases like 'scardeded' and 'foundeded'.
- What The Hell, Nice Girl?: The TV episode "Search for the Sky Colored Stones" shows that Ducky isn't without a dark side. During a hunt for sky colored stones (geodes), her brother gets stuck in a cave opening, and instead of running off to get help she proceeds to find and hoard all the geodes in the cave for herself, intentionally misdirects Ruby and Cera so they never find any themselves, and generally acts like a sneaky, paranoid nutcase.
- Why Are You Looking at Me Like That?: When Littlefoot explains his trap for Sharptooth, he realizes that they'll need bait to lure him into position. Cue a smiling head turn towards Ducky, the only one in the group who doesn't have a job yet. Naturally, she doesn't seem particularly thrilled, but seems to agree to it in the end.
- To give this context, it was a far safer job for her to do than it would been for the other three, given she just needed to lead the Big Bad to a pool of water that she could swim in and he couldn't.
Petrie - Pteranodon
A panic-prone male pterosaur. He's one of the main characters throughout the series. He lives in the Great Valley with his mother and siblings.Appears in all thirteen films and the TV series.
- A Day in the Limelight: He is the main character of "The Great Day of the Flyers".
- Acrophobic Pterosaur: Grows out of it by the end of the first movie, for the most part.
- Cloudcuckoolander: Has a pretty vivid imagination.
- Cowardly Lion
- Crouching Coward, Hidden Hero: Typically overcomes his fears during life-or-death situations, only to immediately react in horror afterwards that he ever did something so dangerous.
- Did You Just Flip Off Cthulhu?: When Petrie finally learns to fly, he celebrates by throwing rocks and laughing at the murderous sharptooth at the bottom of the ravine. This cockiness very nearly ends in tragedy when the sharptooth tries to pull him down with him.
- Disappeared Dad: His father is never seen, and we only ever see his mother and his many, multicolored siblings. Heck, unlike Cera and Ducky's unseen parents, he's not even seen in the original!
- Disney Death: He nearly dies when they kill Sharptooth, but he ends up ok.
- Fantastic Slur: When Petrie first meets him, he refers to Littlefoot as a 'flathead'. Given Littlefoot's reaction to this term, Petrie's lack of racist tendencies, and the fact that Petrie stops using this term soon after it's introduced, he may have unknowingly been using a racial slur that he innocently picked up from somewhere else.
- Hero-Worshipper: Idolizes his uncle and takes everything he says as absolute fact. Unfortunately, his uncle isn't the best of role models.
- Platonic Life Partners: With Ducky
- Plucky Comic Relief: The official website refers to him as "the clown of the group".
- Ptero Soarer: The original movie averted this slightly as while he was still outdated by modern standards the animators gave him features in accordance to then new theories like walking on all four. Unfortunately, the sequels throws all of those features into the trash bin.
- The Smart Guy: Though not so much because he's the most intelligent as he is the most cautious.
- Third-Person Person
- Toothy Pterosaur: While some pterosaurs do have teeth, Pteranodon (Toothless Wing) aren't among them.
- Vegetarian Carnivore: Petrie is a Pteranodon, which are known to dine on fish. Yet, he and other "fliers" are shown eating plants and there's no explanation as to why.
Spike - Stegosaurus
A quiet, ravenous male stegosaurus, and the adopted brother of Ducky. He's one of the main characters through out the series. He lives in the Great Valley with his adopted family.Appears in all thirteen films and the TV series.
- Big Brother Instinct: Towards Ducky (even though he's technically the younger of the two).
- Big Eater
- The Big Guy
- Gentle Giant
- God Guise: In the TV episode "Stranger From the Mysterious Above", a colony of horned gophers thought he was "The Big Wise One" from their religion.
- Happily Adopted: By Ducky's family.
- Inner Monologue: Through out most of the TV episode 'Through the Eyes of a Spiketail', we see the world through Spike's perspective and become privy to more details about his personality through his thoughts and feelings.
- Oblivious Adoption: Deals with issues related to this trope in The Big Freeze.
- Plot-Relevant Age-Up: He is born in the middle of the film while the rest of the gang have grown up to be kids, but grows to their age in a matter of seconds.
- Purple Eyes: During 'Through the Eyes of A Spiketail', a POV shot is given from his point of view, where everything he sees takes on a purple tint.
- Reluctant Hero: He apparently isn't enthusiastic about his friend's frequent adventures outside the Great Valley, and wishes his friends could be more content with staying home and eating.
- Scatting: Keeping in line with his muteness, he scat sings during musical numbers.
- Smarter Than You Look: In one of the TV episodes, Spike's thoughts are revealed. He's actually quite observant, and secretly rolls his eyes whenever Littlefoot and Cera get into a pointless argument.
- Tastes Like Purple: He can apparently "hear" songs from plants, and can even identify them based on their different tune. Given his unusually good smelling abilities shown through out the series, it's possible that Spike is demonstrating an olfactory form of synesthesia.
- The Voiceless: Except for two instances where he yells Ducky's name when she's in danger, and when he yells "Mama!" as he nearly drowns in a lake.
- Later revealed that he can talk but simply chooses not to.
- And, when he does "speak", it's usually unintelligible mumbling. Interestingly enough, in one episode of the series, it's shown that his thoughts are quite sophisticated.
- In several of the songs, however, he can be clearly seen and heard humming and hilariously enough, scat-singing at a few points.
Sharptooth - Tyrannosaurus rex
A vicious, relentless Tyrannosaurus who acts as the primary antagonist of the first film. He's responsible for the death of Littlefoot's mother. He's supposedly killed by Littlefoot and his friends after they drop a rock on him, knocking him into a deep water hole.Appears only in the first film.
- Ax-Crazy: Is noticeably unhinged and needlessly violent even for a tyrannosaurus.
- Badass: Being a Tyrannosaurus rex helps, but even for a T-rex, he seems superhuman.
- The Berserker: His face is always locked in one single expression; pure, unadulterated, pissed-off rage.
- At one point, Mama Longneck smacks Sharptooth with her tail and he smashes into a rock. He responded by pulverizing the rock with repeated headbutts before he does anything else.
- Big Bad: Considered this in the first film.
- Carnivore Confusion: He is a T. rex hunting sentient baby dinosaurs.
- The Dreaded: When even baby dinosaurs know your name, you're this.
- Also, when Littlefoot's mother intervenes, she orders Littlefoot to run. This is notable because baby animals usually stay near their parents during such instances (such as Wildebeest and Bison), and the chances that Littlefoot could run into another hazard without her presence. It also indicates Littlefoot's mother knew she would likely loose the fight, and that no other hazard in the area was as dangerous as Sharptooth.
- Disney Villain Death: Falls off a cliff into a lake and drowns. However, unlike most, his is an intentional one on the part of the heroes, though given the situation, it's hard to blame them.
- Eaten Alive: Possibly what he was doing to Littlefoot's mother during the fight.
- Eye Scream: Littlefoot accidentally stabs him in the eye with a thorn while trying to escape, blinding him in that eye.
- For the Evulz: Unlike most predators, he seems to kill other dinosaurs entirely because he wants to, not because he needs to.
- Hate Sink: When he kills Littlefoot's mother, it's very hard not to hate his guts.
- Hero Killer: Mortally wounds Littlefoot's mother, who, granted, puts up one heck of a fight, and almost kills the main group several times.
- Implacable Man: One of the most notable in western animation. Borders on slasher villain territory.
- Kill It with Water: Meets his end when the heroes use a rock to topple him into a lake. Due to having stubby arms, he can't swim and drowns.
- It's Personal: He hates Littlefoot because he accidentally blinded him on one of his eyes. It´s heavily implied that THIS and his hatred are the reasons why he is going to such extremes to kill dinosaurs that would be of little food to him.
- Knight of Cerebus: Oh yes. The movie was very soft until he showed up. He is arguably the only villain who was treated seriously in the series.
- Made of Iron: His stamina and strength were ridiculous enough, but he survived falling into a deep trench without any actual injury and can smash large rocks with his head with no pain involved.
- Non-Malicious Monster: Definitely averted; one of the things that made Sharptooth so incredibly terrifying was that he didn't just kill for food, he also killed for pleasure and more often, because he was ticked off.
- Not Quite Dead: Is seemingly killed when he falls off a cliff fighting Little Foot's mother. Cera finds out later on he survived and is ticked off!
- Roaring Rampage of Revenge: In the novel version because while Littlefoot fled from him he sent a thorn flying into one of his eyes, half-blinding him.
- In most scenes he has his right eye closed, which supports this.
- Serial Killer: The Other Wiki had him listed among "Fictional Serial Killers". Make of that what you will...
- Super-Persistent Predator: Is dead set on killing the group. Justifed as only a few other dinosaurs are seen during the film, so they may just be the only thing to eat. Also see Roaring Rampage of Revenge.
- Taking You with Me: Bites down on Petrie's tail as he falls into the water.
- The Voiceless: Like almost every sharptooth in the series.
- Unstoppable Rage: He's in a psychotic fury for every moment of screen time. And it is terrifying'.
- Would Hurt a Child: Most definitely, as he literally spends his entire onscreen time trying to kill the five main characters, who happen to be baby dinosaurs.
Mama Longneck - Apatosaurus
A wise, maternal Apatosaurus who deeply loved her only son, Littlefoot, and hoped to lead him to the Great Valley where he could grow up in safety. She dies midway through the first film from injuries sustained by Sharptooth. Bron was her husband.Appears only in the first film.
- Almost Dead Guy
- Badass: She fights off a Tyrannosaurus Rex. You can't get more badass than that. She doesn't fight off the sissy Rexes that you see getting stomped on by the Great Valley adults throughout the rest of the movies. She fights the original Sharptooth, who is Nightmare Fuel in the form of a carnivore and capable of leaping onto her back.
- Family-Unfriendly Death: We never actually see what injuries lead to her death, and considering one of the scenes contains a horrifying shadow shot of Sharptooth biting a chunk of flesh out of her back, it's probably better that we don't.
- What's more, there actually was film footage made depicting more of the the fight between her and sharptooth. Considering Don Bluth had this footage burned, it's safe to say that her death was decidedly non-PG. Going by the footage of the shadow, Sharptooth wasn't just biting chunks of flesh from her back, he was eating them!
- Heroic Sacrifice: It's obvious that she ultimately sacrifices her life to save her save.
- Mama Bear: Oh yes. She protects her son by fighting off a bloodthirsty Sharptooth while an earthquake is tearing apart the land around her.
- Sacrificial Lion
Grandma and Grandpa Longneck - ApatosaurusTwo elderly Apatosaurus who helped Mama Longneck raise Littlefoot since he first hatched. When she dies, they take to raising him in the Great Valley. Believed to be the parents of Mama Longneck, making them Littlefoot's maternal grandparents. They live in the Great Valley with their grandson.Appears in all thirteen films and the TV series.
- Adults Are Useless: Averted. They are the most level headed, intelligent characters in the entire series, the only reason they aren't a bigger help is that they have to deal with the rest of the adults.
- Badass Grandparents: Grandpa can keep up with Doc when it comes to fighting Sharpteeth. And in a battle in a later film, he and Grandma team up to beat a sharptooth into the ground.
- Berserk Button: There are reasons why Bron is content to leave Littlefoot under their protection. Sweet merciful God help you if you fuck with their grandson.
- Big Damn Heroes: Once in a while.
- Cool Old Guy: Grandpa Longneck can hold his own against a Sharptooth. Not bad for an old dinosaur.
- Cool Old Lady: Grandma Longneck has been shown to do the same twice!
- Good Parents: Not only to Littlefoot, but they were also this to their daughter.
- Happily Married: They're very kind and loving to each other.
- Parental Substitute: They've acted as Littlefoot's parents since the first film.
Topps / Topsy / Mr. Three Horn - Triceratops
An aggressive male Triceratops with deep seated prejudice against dinosaurs other than his own kind. He's Cera and Tricia's father, and Tria's husband. He lives in the Great Valley with the rest of his family.Appears in every film except the fourth, appears in the TV series.
- Berserk Button: Lay a claw or horn on his loved ones — and you'll see why he can be incredibly dangerous!
- Divided We Fall: His stubbornness finally gets him and Cera into trouble in Time Of Great Giving, and they end up getting saved by Grandpa Longneck.
- Fantastic Racism: Prejudiced against longnecks. Seems to get along with Grandpa Longneck in the sequels well enough, however.
- Freudian Excuse: The reason why he acts like a grump is for the sake of his family and because his own father was as grumpy as him. The absence of his wife and all of his children besides Cera from the second film onward may also explain it.
- Grumpy Bear: Perpetually.
- Jerk Ass: Is the one who taught Cera her Fantastic Racism in the first film, and he repeatedly causes trouble for all the other grown-ups in the sequels and the series.
- Jerk with a Heart of Gold: He genuinely loves his daughter despite all his other flaws.
- Opposites Attract: It might be hard to believe, but a guy as hard as stone eventually falls for a woman as sweet as sugar. In addition, she's the only one who can calm him down.
- Papa Triceratops
- Antagonist Song: 'I'm Tough' could be considered this in the third film, given what he was doing at the time.
- Well-Intentioned Extremist: He will do anything to protect his family, going to violent lengths.
Rooter - Scolosaurus
A wise, mysterious wanderer among the wastes of the mysterious beyond. His whereabouts are unknown.Appears only in the first film.
- Callback: Possibly one in movie ten. Bron tells Littlefoot that he learned of his mother's death from a passing dinosaur not long after the Great Earthshake, and that this dinosaur also mentioned that Littlefoot survived. Given the timing, this dinosaur was likely Rooter.
- Do Not Go Gentle: Rooter's biggest impact in the series is helping soften the blow of Mama Longneck's death— both for Littlefoot and the younger audience— by confirming to Littlefoot that his mother will always be with him, and that the pain he feels right now will lessen in time.
- Jerk with a Heart of Gold: When he first runs into the crying Littlefoot, he treats him with gruff indifference. When he realizes the boy has just lost his mother, he immediately softens.
- The Obi-Wan
Mama Swimmer - Parasaurolophus or SaurolophusDucky and Spike's mom.
- A Day in the Limelight: Got some more attention in "The Big Freeze".
- Good Parents: All too happy to adopt Spike and is very loving to all of her kids (and there's like thirteen of them!)
- Mama Bear: Won't stand for any harm coming to her kids. Seriously, this mother dives under ice and risks her life to save Spike.
- Pink Girl, Blue Boy: She and her husband have this color scheme in the finale of the first film. She's given a more realistic green color from the second film onward.
Mama Flyer - PteranodonPetrie's mother.
- A Day in the Limelight: Has a bit more focus in "Stone of Cold Fire" and then in "Great Day of the Flyers".
- Deadpan Snarker: Has her moments.
- Good Parents: Especially noticeable in "Stone of Cold Fire", where she makes sure to set a better example for her children than Pterano.
- Mama Bear: Notice a pattern here? She flew through what was essentially a hurricane to find her missing son!
- Sibling Rivalry: Played with; she's set up to have something like this with Pterano, but she has enough faith in him to know that he won't let any harm come to Ducky. She still doesn't think too highly of him, though...
The sequel films
Chomper - Tyrannosaurus rex
A friendly young Tyrannosaurus who was hatched as an egg by Littlefoot and his friends. He later teaches himself the herbivore language, and becomes a speaking character by the fifth film. He and Ruby have been allowed to live in the Secret Caverns to keep safe from Red Claw, making him the only sharptooth living in the Great Valley. He becomes a main character in the TV series.Appears in films two and five, and every episode of the TV series.
- All of the Other Reindeer: It's not explored that much in the TV series, but many leaf eaters of the Great Valley don't trust him for being a sharptooth, and it's implied that this is the reason why he and Ruby have to sleep in the secret caverns separated from the rest of the residents. Chomper spends almost all of his time with his True Companions, so it rarely bothers him.
- Audience Surrogate: Chomper wasn't around for most of Littlefoot's adventures, so he and Ruby receive a lot of exposition whenever they meet one of the characters from the sequels.
- Breakout Character: Definitely the most popular character introduced outside of the original film.
- Carnivore Confusion: Actually addressed. Normal Sharptooth would try to eat the group, but he resolves to only eat bugs in order to stay around his friends, though they do find this disturbing as well.
- Cloudcuckoolander: Sometimes. He tends to forget that his friends are leaf-eaters and offers them insects to eat. He also tends to be naive. Lampshaded by his parents in the fifth movie.
- Compensating for Something: On more than one occasion, he's shown to be very sensitive about being called 'little'.
- Cute Shotaro Tyrannosaur: Especially evident in the TV series.
- Declaration of Protection: He and Ducky get trapped on a rock out crop in the middle of a ravine. With a Utahraptor. He assures Ducky that he'll protect her while openly declaring to the raptor that he will fight him if he tries to hurt her.
- Dino Bites Dino: Chomper chomps down on Cera's tail (by instinct) in the second movie and an Giganotosaurus's tail (to protect his friends) in the fifth movie.
- Double Entendre: He just loves having friends for dinner...
- Enfant Terrible: Averted, despite being an infant Sharptooth, he's a very nice guy. However he is often mistaken for this by dinosaurs that don't know him. In fact in one episode of the TV series spinoff, it almost gets him killed.
- Guest Star Party Member —> Permanant Party Member
- I Am What I Am: Says this word for word in the fifth movie, pointing out that nobody has any control over what they're born as, and that people of very different races can still be close friends.
- I Just Want to Have Friends: He seems to have been very lonely on his island before his old friends stumbled upon it. He's less like this in the TV show, but he does seem still seem vulnerable to feeling like the odd one out.
- My Species Doth Protest Too Much: His parents are the only Sharptooth he actually seems to like, otherwise he actually prefers to hang with the Great Valley dinos over his own kind. Probably because other adult Sharptooth seem to attack him on sight as well.
- Nervous Wreck: Not to the extent that Petrie is, but Chomper does have a habit to jumping to the worst conclusions when he's scared. After his first baby tooth fell out he thought that he was literally falling apart, and he assumed that Doc, the lone dinosaur and expert fighter of vicious sharpteeth, returned to the Great Valley with the intention to kill him, even though Doc couldn't have known he lived there in the first place.
- However, it makes sense that Chomper would be a bit worried about a supposed hostile longneck coming to the Great Valley after he was nearly killed by a herd of them when they also mistook him for a vicious sharptooth.
- Nice Guy: In spite of being a T. rex.
- Omniglot: He's the only known Sharptooth to be able to speak Sharptooth and plant eater. This comes in handy at times. Most dinosaur adults seem suitably suprised upon learning of this.
- Raised By Herbivores: Even though it was only for the first few days of his life, it's had a considerable impact on him.
- Red Eyes, Take Warning: Averted; Chomper has very red eyes, yet he's a good and kind person. People who don't know him, however, tend to take the trope to heart as soon as they see him.
- Ridiculously Cute Critter: In every appearance, but most obviously in the first one.
- Sixth Ranger (in animated series)
- Spotlight-Stealing Squad: Anyone who doesn't consider him an Ensemble Darkhorse thinks of him as this in the animated series. Of all the characters, he has the most number of episodes focused around him.
- Undying Loyalty: Dedicates his life to an altered diet so he can stay friends with his leaf eater companions.
- Vegetarian Carnivore: Played with, as he occasionally samples "green food" in an effort to fit in, but finds it disgusting.
- Wide-Eyed Idealist: After feeling isolated at being the only sharptooth in the Great Valley, Chomper convinced himself that he could to teach sharpteeth from the mysterious beyond to be nice. It doesn't work and it almost gets him killed.
Chomper's parents - 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.Appears in films two and five.
- Badass: Well, they are T. rexes. After being initially injured by the Plated Sharptooth, Papa Rex stands up and ends the fight with one decisive blow of his tail. It also took a group of at least four adult leaf eaters to chase them off.
- Badass Adorable: And they're downright adorable when they're with their son.
- Battle Couple
- Deadpan Snarker: Chomper's father. "Sometimes I worry about that boy."
- Good Parents
- Happily Married
- 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 part the reason they sent Chomper to the Great Valley in the series, to protect him from Red Claw.
- Monster Is a Mommy: They leave the Great Valley as soon as they find their son.
- 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.
- Red Eyes, Take Warning: They aren't really villainous, but they are dangerous, and they have the eyes to match .
Ozzie and Strut - StruthiomimusesA duo of bumbling egg stealers who infiltrate the Great Valley in order to prey upon the smorgasbord of eggs withinAppears in film two only.
- Bumbling Sidekick: Strutt.
- Butt Monkey: Both of them, though Strut usually gets the worst of it.
- Determinator: Ozzie.
- Evil Brit: Ozzie.
- Exit, Pursued by a Bear: They get chased off by Chomper's parents in the end.
- Large Ham: Ozzie.
- Laughably Evil
- Jerk Ass: Ozzie to Strut.
- Starter Villains
- Those Two Bad Guys
- Vegetarian Carnivore: Ozzie and Strut are both Struthiomimuses. Strut seemed more content with eating plants, while Ozzie seems obsessed with eating eggs. In reality, Struthiomimus and its relatives were omnivores, and having such restricted diets would probably be a death sentence.
- Villain Song: 'Eggs'.
Hyp, Nod and Mutt - Hypsilophodon, Nodosaurus, and MuttaburrasaurusAppears in film three and an episode of the TV series.
- Aesop Amnesia: They're back to being troublemakers in the TV series, but they're not as bad as they were in the third film so they probably at least learned something since then.
- Brains and Brawn: Hyp's the brains, Nod and Mutt are the brawn, but especially Mutt.
- Butt Monkey: Mutt gets slapped around a lot.
- Deadpan Snarker: Hyp is quite the wiseass before he mellows out.
- Frame-Up: Get Littlefoot in trouble by pushing him into the water off a low cliff, making the scare 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 Topsy. And Topsy's on of the adults to seriously call Hyp's dad out on it.
- Gang of Bullies
- Big Thin and Short Trio: Mutt (big), Hyp (thin), and Nod (short).
- 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.
- Jerkass —> Jerk with a Heart of Gold
- 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.
Ali - Apatosaurus
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.Appears in film four and an episode of the TV series.
- Distaff Counterpart: Ali looks almost exactly like Littlefoot. Lampshaded by Petrie, who mistakes her for a second Littlefoot when he first sees her.
- Fantastic Racism: Not as bad as Mr. Threehorn gets, but she initially wasn't comfortable interacting with dinosaurs who weren't longnecks.
- Guest Star Party Member: In Journey Through The Mist
- Pale Females, Dark Males: Ali is more pinkish than Littlefoot, who is more grayish.
- Walking the Earth: Her herd is migratory, after their homeland was ruined by constant rain and floods.
Old One – ApatosaurusThe 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.Appears in film four and an episode of the TV series.
- Reasonable Authority Figure: 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.
- Walking the Earth
- 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 decides they still want to kill him.
Ichy and Dil - Ichthyornis and Deinosuchus
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.Appears in film four only.
- 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.
- Exit, Pursued by a Bear: after 'parting ways' with Ichy, Dill is chased off screen by a very hungry looking plesiosaur
- Never Smile at a Crocodile: Dil, although she's a bit less competent than most.
- Teeth-Clenched Teamwork: They are partners, not friends. They make it clear they're only together out of necessity.
- Those Two Bad Guys
- Toothy Bird: Justified, as Ichy is an Ichthyornis, which had teeth in real life.
- 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.
Elsie - ElasmosaurusAn inexplicably British plesiosaur that accidentally frightens Chomper and Littlefoot. She gladly helps our dinosaurian heroes relocate their parents.Appears only in film five.
- 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.
- 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 Littlefoot & Co back to the mainland
- Nice Lady
- 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 - Giganotosaurus
An unnamed, vicious Giganotosaurus living on the Mysterious Island. He acts as the main antagonist of the fifth film. He's drowned after being pushed off a cliff into the ocean.Appears only in film five.
- Darker and Edgier: Sharpteeth, particularly unnamed ones, are generally portrayed as incompetent villains, but the Plated Sharptooth harkens more to the vicious, relentless threat of the original Sharptooth.
- He holds the distinction of being the only character other than the first Sharptooth to ever draw visible blood on screen.He slashes Chomper's father's nose with his claws◊, and then slashes his mother's leg with his toes.
- Determinator: Most sharpteeth in the series will run in fear the moment that adult flateeth make the scene. The Plated Sharpteeth was perfectly willing to stand and fight two other adult sharpteeth at the same time.
- He does have one Lighter and Softer moment where he accidentally bites his own tail, tearing up as he does so.
- Implacable Man: While not quite as unstoppable as the sharptooth of the first film, he's displayed unusual persistance by jumping over chasms and fighting off other sharpteeth in an attempt to get at the heroes.
- Knight of Cerebus: Calls back more to the original Sharptooth in terms of sheer viciousness. Aside from one aforementioned comedy moment, the Plated Sharptooth was 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 to the water with him when he falls, the Plated Sharptooth knocks Chomper off a cliff and into the ocean along with him.
Doc - Diplodocus
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.Appears in film six and an episode of the TV series.
- Clint Squint
- The Drifter
- 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'.
- Jerk with a Heart of Gold: In the TV series, at least. In his first appearance, he isn't very personified.
- Red Baron: The Lone Dinosaur
- Good Scar: A thin, jagged one over the right side of his face.
- Warts and All: Doc fits this trope from the time he condemns Littlefoot's friendship with Chomper until the time he repents for it.
- Whip It Good: What he uses his tail for.
Dana and Dinah - TriceratopsAppears in film six only.
- Annoying Younger Sibling: For Cera—although Cera's technically their aunt and not their older sister. * Chuck Cunningham Syndrome: They disappear after Saurus Rock. Presumably, they went back to live with their parents.
- Fearless Infant: They are totally oblivious to any kind of danger!
Pterano - Pteranodon
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.Appears in film seven only, though is mentioned a few times in the TV series.
- Affably Evil: He's a pretty nice guy, despite his nastier qualities.
- 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.
- Big Bad: Of Stone of Cold Fire, though he doesn't stay that way.
- Cool Uncle: Petrie thinks he is.
- Dangerously Genre Savvy:Rinkus: Why not simply ask the longneck to tell us where [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!
- Dirty Coward: Accused of being one, after his disastrous leadership.
- 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 genuine sorrow when Ducky appears to have fallen to her death 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
- Evil Uncle : But he has a Heel-Face Turn.
- It's All About Me: His theme song, "Very Important Creature" highlights this. He's motivated by a big superiority complex.
- Jerk with a Heart of Gold
- My God, What Have I Done?: He has this response a lot. Most notable is the one listed directly below.
- 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.
- Never My Fault: His Fatal Flaw.
- Pride: He has a very overinflated opinion of his leadership abilities.
- Ptero Soarer: Unlike his nephew, he was unlucky to be a sequel character, and hence whatever accuracy the original movie's pterosaurs had was not carried on.
- 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 as such.
Sierra and Rinkus - Cearadactylus and RhamphorhynchusTwo conniving pterosaurs that associate themselves with Petrie's uncle Pterano. However, they seem to have plans all their own...Appears in film seven only.
- Brains and Brawn: Rinkus is the brains and Sierra is the brawn.
- Dangerously Genre Savvy: Rinkus points out to Sierra that it would be inconvenient to 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...
- Dirty Coward: Rinkus. Or so it seems...
- Foreshadowing: Rinkus' darker side is hinted at several times in the movie, like not so subtley implying that he wanted to threaten Littlefoot with violence or even death if he doesn't tell them the location of the stone.
- Murder Is the Best Solution: Sierra suggests feeding the main characters to sharpteeth.
- Rinkus says that should kill Littlefoot if he doesn't give them information about the stone.
- Not So Harmless: Rinkus, who proves himself to be a pretty nasty schemer on several occasions.
- Obfuscating Stupidity/Beware the Silly Ones: 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 beligerent coleague) is conveniently availiable.
- Ptero Soarer: Same as above.
- 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.
- The Starscream
- Those Two Bad Guys
Rainbow Faces - GallimimusA 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.Appears in film seven only.
- 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.
- 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.
- 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 too many of them!
Mr. Thicknose - PachyrhinosaurusAn 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.Appears in film eight and several TV episodes.
- Ascended Extra: Appears in only one film, becomes a regular character in the TV series.
- Cool Old Guy
- 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.
- 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 - StegosaurusAppears in film eight and one episode of the TV series.
Mo - OphthalmosaurusAn 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.Appears in film nine, makes cameos in films ten and twelve, and appears in one episode of the TV series.
- Blood Brothers: Sort of. In the ninth film, he and Littlefoot become 'mud brothers', a PG equivelant.
- Disney Death
- Guest Star Party Member
- Heroic Sacrifice: Narrowly escapes a swimming sharptooth when it changes direction while he hides in a hollow log.
- Keet: The little guy has tons of energy.
- 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.
- Third-Person Person
Sharptooth Swimmer - LiopleurodonA 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.Appears in film nine only.
- 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 them, but its clear than it is just trying to get home, and stops antagonizing the kids after it smells the ocean.
- Sea Monster: Well, it is a Liopleurodon, so what did you expect? It to be eating cheese?
Bron - Apatosaurus
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 visits the valley very frequently.Appears in film ten and one episode of the TV series.
- Badass: Being the leader of his own heard doesn't mean he's gotten soft in how to fend off Sharpteeth. Must run in the family.
- Disappeared Dad: He left to find a suitable place to live before Littlefoot's birth and by the time he returned, the Great Earthshake had occurred.
- Genre Savvy: Bron is, to date, the only adult in the film series that told Littlefoot to go help fight a Sharptooth, instead of to run away. Apparently, when Littlefoot described his childhood of beating every Sharptooth he encountered, Bron was actually listening.
- 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.
- 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.
- Reality Ensues: Sorry, Bron, your son is not going to instantly accept you when he finds out you're his father. Indeed, Bron ends up having to explain, in detail, where he was for all that time and why he was never there for him to get Littlefoot to forgive him.
- 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.
- Parental Substitute: To Shorty.
- What the Hell, Dad?: Doesn't show up until the tenth movie. Littlefoot is understandably upset that he's been a no-show for almost NINE SEQUELS.
- The plot of the fourteenth film (yes, it is still going), involves him not appearing for a visit to his son when he was expected. This may or may not end in tragedy.
Shorty - BrachiosaurusAn 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.Appears in film ten and one episode of the TV series.
- 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.
- Happily Adopted: By Bron.
- Jerk with a Heart of Gold/Jerkass
- 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 step-brother's leadership talents.
Tria - Triceratops
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.Appears in films eleven, twelve, and thirteen, as well as multiple TV episodes.
- Beast and Beauty: She seems to be the only adult in the series capable of soothing Cera's hot-headed father.
- Brooding Boy, Gentle Girl: The gentle girl to Topsy's brooding boy.
- Evil Stepmother: Greatly averted. Despite an initial clash between them, Tria's been shown to genuinely love and care for Cera as if she were her own daughter.
- Good Parents: She's a good parent to her biological daughter and a good stepparent to her stepdaughter.
- Minnesota Nice: In the TV series, at least. There are hints of the accent in her inflections, and she certainly has the polite behavior.
- New Old Flame: To Topsy.
Guido - MicroraptorAppears in film twelve and one episode of the TV series.
- Butt Monkey
- Instant Expert: Has no problem flying, as long as he is asleep. Later learns to do it for himself.
- 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...
- Remembered I Could Fly: See above, and only after everyone tells him he can.
- Plucky Comic Relief: Pulled off decently for a direct-to-DVD character.
- 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.
Loofa and Doofa - BeipiaosaurusAppears only in film thirteen.
- Call a Rabbit a "Smeerp": They're referred to as 'Yellow Bellies'
- Cloud Cuckoo Landers
- Does This Remind You of Anything?: Doofa 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.
The television series
Ruby - Oviraptor
A whimsical female oviraptor who acts as Chomper's guardian in the Great Valley while he lives away from his parents. She and Chomper live in the Secret Caverns, a system of caves in the Great Valley. She becomes a main character in the TV show.
- Cloud Cuckoo Lander:Ruby: "I'm right here... Of course, I'm always "here", and "here" is where ever I am."
- Cool Big Sis: Ruby is the oldest of the kids and goes between this and Team Mom, especially for Chomper.
- Department of Redundancy Department: Often. See Verbal Tic.
- Nice Girl: She's always looking out for the group, and she always comforts Chomper when he's upset.
- Only Sane Dinosaur: Much like Littlefoot.
- Parental Substitute: She acts as a guardian to Chomper while they live in the valley.
- Promotion to Parent: Since neither Ruby and Chomper were accompanied by their families to the Great Valley Ruby has become a sisterly version of this to Chomper.
- The Reliable One: Chomper's parents leave her in charge of their kid for a reason.
- Remember the New Guy: She and Chomper are already with the main cast on the first episode without any mention of her past. Even though she gets more details explained later it's quite egregious.
- Shown Their Work: Her species are portrayed with feathers and as omnivores instead of egg-eaters.
- Seventh Ranger
- Tomboy and Girly Girl: Girly Girl to Cera's Tomboy. (One of two)
- Vegetarian Omnivore: Averted. While she likes eating plants (her favorite food is grapes, in fact), she's also seen eating a shellfish at one point, which would classify her as an omnivore. You know, just like real Oviraptors were.
- Verbal Tic: Tends to say things twice, but the second time switching the structure of the statement around. It can get a tad annoying, but does provide a thoughtful line here and there.
- Wise Beyond Their Years: Ruby, despite being only a little older than the main characters, has much more wisdom than the others because unlike them, she spent most of her life in the mysterious beyond associating with leaf eaters and sharpteeth alike.
Red Claw - Tyrannosaurus rexAn uncommonly powerful Tyrannosaurus who's terrorizing the mysterious beyond. He lives on the outskirts of the Great Valley.
- Big Bad: Of the TV Series
- Expy/Shout-Out: Of the original Sharptooth. Just like the original sharptooth, Red Claw causes such widespread fear that even other sharpteeth try to keep away from him. Also telling is his one discolored eye, likely a reference to the original sharptooth getting stabbed in the eye with a thorn.
- Evil Scars
- Informed Ability: He's said to be one of the biggest, baddest Sharptooth of all time, but he's constantly defeated by a group of children...though said children have a long record of beating Sharptooth.
- That said, he's never shown to be nearly as vicious as the original sharptooth.
Screech and Thud - Utahraptor
- Evil Is Dumb
- Evil Minions
- Makes Us Even: Not long after Chomper helps free him from a pile of rocks, Thud finds him and the rest of the gang trapped inside a small cave near a canyon wall. Instead of alerting Screech and Red Claw, he leads them in the opposite direction of where the kids are hiding.
- Raptor Attack: Besides lacking feathers, they have two fingers instead of three.
Rhett - Apatosaurus
- Break the Haughty: Brags that sharpteeth fear him...until he has to deal with an actual one. And said actual sharptooth isn't even bigger than him.
- Dirty Coward: The exact instant he's faced with a real sharptooth, he turns tail and runs. What makes this different from the other characters is that this sharptooth was about a tenth his size.
- Miles Gloriosus: He brags about outlandish feats of strength and bravery to impress people. Littlefoot and Cera aren't fooled by Rhett's stories, but Ali is.
Milo, Lydia, and Plower - Ceratogaulus
- Anachronism Stew: Ceratogaulus or horned gophers lived from the Milocene to the Pleistocene, after the dinosaurs became extinct.
- Nay-Theist: Plower was initially skeptical that Spike was "The Big Wise One", but becomes convinced when Spike inadvertently defeats the Great Hideous Beast.
- Seldom Seen Species: Probably the first time you see horned gophers in a cartoon.
Great Hideous Beast - Microceratus
- Killer Rabbit: Subverted. Due to his tiny size he can barely pose a threat to Spike, who defeats him and traps him in a rock pile by mere accident.
Dara - Diplodocus
- Love Interest: For Doc.
Scuttle - Crustacean
- Enraging the Ice Queen: Scuttle abuses the fact that the gang needs his help by sending them on dangerous fetch quests for his favorite food. Cera is aware she's being taken advantage of, and she is not happy about it. His third request which was to build him a nest becomes the last straw for Cera.
- Expy: A greedy, confrontational crab with long eyestalks, a pirate accent, a penchant for telling stories, and a chortling laugh? All he's missing is a burger-joint.
- Ice Queen Has a Point: When it becomes clear that Scuttle has no real intent on going to the Great Valley to help with the sand creepers, Cera points out that he'll have no one to tell any of his stories to. Unable to bear having no one to tell stories to, he abides by the gang's request.
- Omniglot: He's apparently the only crab capable of communicating with dinosaurs.
- Teeth-Clenched Teamwork: Because Scuttle is the only person capable of communicating with the sand creepers that have infested the Great Valley, the gang can't afford to refuse his requests. But as scuttle keeps asking for more favors, the gang's patience rapidly wanes— particularly Cera.
Crunch - Crustacean
- Arch-Enemy: To Spike, despite Ducky thinking otherwise. Crunch keeps snapping painfully onto Spike's nose whenever the oppertunity presents itself. Spike eventually gets so irritated that he chases Crunch out of the valley.
Swooper - Harpactognathus
- Cloudcuckoolander: All those years of living as a hermit (and possibly as well as his blindness) have caused him to become acquainted with some cave formations, even giving them names. This is even lampshaded by Guido.
- Cool Old Guy
- Ptero Soarer
