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: While the original five are all right, mostly being earth tones, for some reason Chomper is purple and Ruby is pink with hot-pink spots.
- Beware the Nice Ones: Cera can be a jerk, but for the most part they're all nice. Hasn't stopped them from killing Sharpteeth.
- Brother-Sister Team:
- Ducky and Spike, being a duo of two foster siblings since the moment Spike hatched in the first film.
- Ruby and Chomper are also sort of this, with Ruby often taking on a sisterly role as Chomper's guardian.
- 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'. Justified, as the characters are real creatures in a real period of Earth's history, but without the human languages that gave them their names.
- 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.
- Spike eats his own nest.
- Petrie falls screaming from a tree, gets tossed around a bit, then excitedly asks if he flew.
- Fire-Forged Friends: The classic lineup were forced to work together in order to survive the hellish conditions of the first film.
- Five-Man Band: Formerly this (Littlefoot, Cera, Petrie, Spike, Ducky), 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, 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.
- Interspecies Friendship: All the heroes are different species of dinosaur.
- Kid Hero: All seven of them fit, although their ages are never definitively stated in the films themselves. Character sheets of the first movie for both Littlefoot◊ and Cera◊ state that they're five years old. Ruby is assumed to be the eldest of the gang. While Cera claims to be the oldest of the original five, Ducky's birth is shown before Cera's (which is then followed by Littlefoot's), whether or not that actually is the order in which they were born. 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, Hero!: 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-knit group. It gets even more bizarre when a friendly Tyrannosaurus and a whimsical Oviraptor get added to the crew.
- Pragmatic Hero: All of them; given their diminutive size, they're not adverse to fighting dirty when confronted with sharpteeth. In fact, they've got a body count.
- 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. And Ruby is something of this by the series.
- True Companions: They've been through more predicaments than most groups of friends in fiction. Especially highlighted in Great Longneck Migration where Littlefoot is so moved by the length his friends go to try to find him that he ulimately chooses to go back to the valley with them instead of staying with his newly found father.
- Vitriolic Best Buds: Littlefoot and Cera are often at odds with each other even at the best of times, and in some films they have actually traded blows with each other. Still, the two always seem to settle their differences in the end and remain close friends.
- "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).
Appears in all fourteen films and the TV series.

- "Awesome McCool" Name: Or at least, it would have been if they had gone with the original name for the character: Thunderfoot. In-Universe, his name actually comes from Mama Longneck naming him after Bron's childhood nickname of "little foot".
- 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: He displays a protective streak towards Ducky ever since she brings him out of the deep depression he was in after his mother's death in the first film, and he displays a similar instinct towards Chomper from the very moment he hatches, even going as far as protecting him from his other friends at times.
- Comforting Comforter: He tucks Ducky under Spikes tail during the final verse of "Always There" in The Mysterious Island shortly before going to sleep himself.
- Demoted to Extra: Downplayed. In the TV series, he's still a main character, though the amount of episodes focusing primarily on him can be counted on one hand.
- Disappeared Dad: Played straight until The Land Before Time X: The Great Longneck Migration.
- Disapproving Look: Gives this to Cera in "The Great Day of the Flyers" when she seemed reluctant in rescuing Guido from the Mysterious Beyond.
- 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. He only comes out of it after meeting Ducky.
- Hero-Worshipper: For Doc in the sixth film. He spends a good chunk of the movie following him around and is more than enthusiastic about Doc saving his life multiple times. However, he redirects his hero worship to his grandfather.
- How Dare You Die on Me!: While talking with Rooter, Littlefoot tearfully says his mother should have known better than to fight the sharptooth. This is likely just a statement out of intense grief, as her death leaves him completely alone in the world.
- It's Personal: Not outright stated, but when the opportunity to kill Sharptooth appears, Littlefoot is the first to take it, and he immediately works out a plan for him and the others to bring Sharptooth down. 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.
- Jerkass Ball: In Journey of the Brave, during an argument with Cera, Littlefoot tears into not only her but the rest of his friends sans Chomper and Ruby by accusing all of them of holding him back in rescuing his dad.
- Nerves of Steel: If something's going wrong, Littlefoot's generally the one who keeps his head together.
- Nice Guy: He is friendly, brave, selfless, compassionate, and forgiving. Along with Ducky, he is easily the kindest and most levelheaded of the main cast.
- Raised by Grandparents: After Littlefoot's mom dies, his maternal grandparents have assumed guardianship of him to this day, due to his decision not to live with his dad.
- Red Is Heroic: His eyes are a shade of reddish brown that varies anywhere from mahogany to maroon between movies.
- Red Oni, Blue Oni: The calm, reasonable Blue to the hot-headed Cera's Red.
- Screw the Rules, I'm Doing What's Right!: Frequently breaks the rules in order to fix a problem that the adults won't.
- Screw This, I'm Outta Here!: After Cera insults his mother and then adds injury to insult by soundly defeating him in a No-Holds-Barred Beatdown, Littlefoot is not happy when the others say they would rather go with Cera since her way is "easier."
- Siblings Wanted:
- In the ninth film, Littlefoot laments that he has no brothers or sisters to play with. One movie later, he gets 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.
- 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.
- Tertiary Sexual Characteristics: Inverted: a notable part of Littlefoots design is his long, feminine eyelashes, despite being a boy.
- Trademark Favorite Food: Mutha fuckin' treestars, bitch!
- Undying Loyalty: He will never abandon his friends and family.
- 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.
Appears in all fourteen films and the TV series.
- Voiced by:
Candace Hutson (original film, II-IV)
Anndi McAfee (V-present)
- Absentee Actor: She is absent from the final episode of 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.
- She's kind of a grey area for her niece and nephew, Dana and Dina, since she often gets annoyed by their antics. However, she still loves them and freaked out when they disappeared.
- Big Damn Heroes: After separating from the group, she returns to deliver the final blow to defeat the Sharptooth once and for all.
- 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. Much more literally in the first film, when she despises the group's company thanks to her Fantastic Racism, but has to stick together to avoid starving, freezing, or getting eaten. note
- In the TV series: "I'll believe it when I see it."
- She does her Haughty "Hmph" often enough that it's practically one of these as well.
- Changed My Mind, Kid: Returns to the group in the last minute at the climax to help them defeat Sharptooth.
- Commander Contrarian: At times it seems like her whole reason for existing in the plot is just to disagree with whatever plan Littlefoot has come up with. Some of her criticisms are justifiable, during occasions where Littlefoot gets a bit overly exuberant, but even then, she almost never offers an alternative. A perfect example would be during The Stone of Cold Fire, in which she protests against the idea of crossing a chasm via some extremely flimsy vines. While she's perfectly correct that the idea is very dangerous, when asked if she has any other ideas, she has no choice but to reluctantly fall in line.
- 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.
- Dirty Coward: In the first film. Brags about how brave she is when there's no enemy around to prove her mettle, and even headbutts targets she doesn't think can/will hit back (her sisters and parents when she's born, insects, frogs, what seems to be a dead Sharptooth...), but the second she's faced with something that can harm her (lightning, a very much alive Sharptooth...) she runs screaming.
- Fantastic Racism: Especially in the first film. She mellows pretty fast, though.
- Fantastic Slur: In the first film. And unlike Petrie, she's not an Innocent Bigot.Cera: My father told me that flatheads had very small brains.
- 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. And again with her half-sister Tricia.
- 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. Interestingly, when Anndi McAfee started voicing her, she became somewhat more aggressive.
- Haughty "Hmph": She does this almost nonstop in every appearance she's ever made, to the point that she rarely goes fifteen minutes on screen without grunting one.
- Humiliation Conga: Suffers one in the first film after going the wrong way. First she is ambushed and nearly devoured by a pack of vicious predators. The predators are scared off by an even more horrifying monstrosity that makes its way towards Cera and picks her up, terrifying her. Only it turns out that it's just the other kids covered in tar. Once Cera realizes this, she appears happy and relieved for just a moment. Until the other kids all start laughing at her, angering her. She wrenches herself free from them and clumsily falls to the ground, making them laugh harder. She furiously tries to insist she knew it was them all along, but it's obvious none of them believe her. She starts to storm off, then slips in a puddle of tar and falls over, causing the others to laugh at her again. Then she bonks her head on a thick stalactite, making the others all laugh once more. She then takes off completely. All of this, along with the knowledge that she'd been in the wrong the whole time, causes her to break down into tears the second she's alone.
- 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 Jerkass, only just redeeming herself in the final act.
- Kick the Dog: In the first movie, after she insults Littlefoot's mother and the two fight, the film makes it clear that Cera won a swift and decided victory. However, rather than letting Littlefoot walk away with some dignity, Cera rubs salt in the wound by delivering one last blow after his back was turned and he had given up, then gloats with a triumphant "Ha!" Littlefoot is so angry afterwards that he cries with frustration and helplessness, and the film makes it clear that that was a low blow even for her.
- Know-Nothing Know-It-All: In the first film, she constantly brags to the others about how she alone knows how to do things (how to get across the chasm, how to get green food, how to reach the Great Valley), and she's almost always wrong.
- Laser-Guided Karma: The receiving end of this in the first movie when she suffers through a Humiliation Conga.
- Meaningful Name: Derived from her genus name of Triceratops.
- Missing Mom: At the beginning of the movie, Cera is seen with both of her parents, but at the end, her mother is nowhere to be seen and is never seen nor mentioned in the sequels.
- My God, What Have I Done?: In the first film after she refuses to follow Littlefoot and leads the other dinosaurs down a different path, which nearly gets them killed, and she narrowly escapes death herself from a pack of predators. She is only saved by the timely intervention of her friends, who disguise themselves in tar to scare off the predators, and they even use the opportunity to prank her. The combination of that, the realization she'd been wrong all along, and even implied guilt over earlier insulting Littlefoot's mother and being ashamed of her own fear, causes her to skulk off on her own before she breaks down into sobbing.
- Neat Freak: Cera hates getting covered in muck or foul substances of any kind, and usually puts up quite a fuss if the journey requires it of her. This also applies to 'stinkweed', which she's forced to cover herself with in films five and fourteen to hide her scent from sharpteeth.
- Nice Job Breaking It, Hero!: After her fight with Littlefoot, she leads everyone into a complete danger zone, nearly getting them and herself killed.
- O.O.C. Is Serious Business: In Invasion of the Tinysauruses, when she finds her friends crying in remorse over chasing Littlefoot away, she suggests they apologize to him in an unusually calm and gentle manner.
- Rage Breaking Point: Cera already had little patience with Scuttle, but the crustacean asking one favor too many (plus getting sucked underwater by a whirlpool twice when trying to get the water greens he requested) becomes the last straw for her and she explodes at him to gather up the sand-creepers in the Great Valley or else there will be no one to listen to his stories.
- Signature Laugh: A smug little "Hee...", usually done when she succeeds at accomplishing something. Lampshaded in one of the sequels wherein she actually says it in a slightly nervous voice as opposed to actually laughing, right before she falls into a river.
- 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.
- Took a Level in Kindness: While she's still egotistical and abrasive in the sequels, she's mellowed out considerably from the first movie.
- Tsundere: She's stubborn, spoiled, and arrogant, and often hides her true feelings behind sharp-tongued rudeness.
- The Unapologetic: She refuses to apologize for calling Littlefoot's mother stupid or for putting everyone in danger, out of her pride and her inability to admit to her wrongdoings, although she does wander off on her own and subsequently breaks down crying after she realizes how badly she messed up.
- 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.
- Unwitting Instigator of Doom: The whole plot of Invasion of the Tinysauruses wouldn't have happened if Cera didn't make fun of Littlefoot about his size, which led to him knocking off the tree-sweets in the first place.
- Why Did It Have to Be Snakes?: 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.
Appears in all fourteen films and the TV series.
- Voiced by:
Judith Barsi (original film)
Heather Hogan (II-IV)
Aria Curzon (V-present)
- Action Girl: Her attempt to bait the sharptooth in the original definitely counts as this.
- Badass Adorable: Don't let her size fool you. If you're threatening someone she cares about, especially her little brother, she will stand up to you.
- Big Sister Instinct: She loves Spike to death. She even started attacking a T. rex when he was paralyzed with fear.
- Catchphrase: "Yep yep yep!" Sometimes modified to "Nope nope nope."
- Cheerful Child: Ducky is almost always happy and very excitable.
- The Chick: Ducky is the more girly of the groups females, in contrast to Cera's tomboyishness.
- Cuddle Bug: Ducky tends to be pretty liberal on initiating physical contact with people, and often grabs their hand, tail, appendage, or even pull them into a hug without any warning. The usual recipient of this is Spike, but she's also done it to Littlefoot, Petrie, and Chomper.
- The Cutie: Her pep, positivity, and friendliness makes her this out of the original five, and she still shares the role nowadays with Chomper.
- 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...
- The Heart: Along with Littlefoot.
- Jerkass Ball: 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. She ends up having a Heel Realization after a life or geode decision.
- 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.
- Manic Pixie Dream Girl: Platonic version. When they first meet, Ducky pulls Littlefoot out of his long-standing depression (from losing his mother and being rejected by Cera) due to her cheerful, sunny disposition.
- Massive Numbered Siblings: Besides Spike, Ducky hast at least 3 other sisters, but in movie six, she mentions that she was originally part of a nest of 13 twins, so she understands twin talk very well.
- 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.
- Nice Girl: The nicest of the gang along with Littlefoot, Chomper, and Ruby.
- Not-So-Innocent Whistle: While trying to muster up the nerve to call Sharptooth's attention to her, she hums nervously under her breath.
- Older Than They Look: Besides Spike, she arguably acts the most naive and childlike of the group, though the first film shows she is in fact slightly older than Cera and Littlefoot.
- 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.
- Tree Cover: Her smalls size means she often walks in on important conversations unnoticed. See Spanner in the Works.
- 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. She will rarely, if ever, use contractions and will say can not and do not instead of cant or dont. Finally, she'll occasionally add needless tense modifiers at the end of words, resulting in phrases like 'scardeded' and 'foundeded'.
- 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 have been for the other three, given she just needed to lead Sharptooth to a pool of water that she could swim in and he couldn't.
Appears in all fourteen films and the TV series.
- Voiced by:
Will Ryan (original film)
Jeff Bennett (II-present)
- Acrophobic Bird: Grows out of it by the end of the first movie, for the most part.
- Big Damn Heroes: In "Great Day of the Flyers", he saves Guido right when he's about to get chomped by a Spinosaurus.
- Brutal Honesty: Briefly, in "The Big Freeze":Littlefoot: You believe me, don't you Petrie?
Petrie: Oh sure! But then me believe anything.
- Butt-Monkey: Bad things tend to happen to him a lot in the series. Things like crashing into obstacles while flying, getting scared, or getting accidentally sat on by Spike tend to be Played for Laughs. Other things, like his clumsiness getting him bullied by his siblings or the various misfortunes that come with his idolization of his uncle, are usually presented more seriously.
- Cloudcuckoolander: Has a pretty vivid imagination.
- Cowardly Lion: He's mostly timid, but can become very brave when the situation calls for it.
- Crouching Moron, Hidden Badass: Typically overcomes his fears during life-or-death situations, only to immediately react in horror afterwards that he ever did something so dangerous.
- A Day in the Limelight: He is the main character of "The Stone of Cold Fire" and "The Great Day of the Flyers".
- 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.
- Easily Impressed: Probably the easiest member of the group to dazzle. This especially shows in The Stone of Cold Fire where we see him being utterly enthralled by his uncle's tall tales. In the TV episode "The Brave Longneck Scheme", Petrie was very eager to meet Rhett when Littlefoot and Cera explain the made-up stories he told them and Ali.
- Hero-Worshipper: Idolizes his uncle and takes everything he says as absolute fact. Unfortunately, his uncle isn't the best of role models.
- Hypocrite: In Invasion of the Tinysauruses, he tells off Ducky for chewing Littlefoot out when he was just as guilty about it as she and Spike are. He gets called out for it, leading to a Jerkass Realization (on all three sides).
- Innocent Bigot: 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.
- Platonic Life-Partners: With Ducky.
- Plucky Comic Relief: The official website refers to him as "the clown of the group". Occasionally he even plays jokes on his friends, like triggering Cera's fear of heights as she crosses a log in Mysterious Island by flying in front of her face and forcing her to look down. However, most of the time he's the subject of jokes and misfortune rather than the giver.
- 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.
- Super Gullible: He pretty much says word for word that'll he'll believe anything.
- Toothy Bird: While some pterosaurs do have teeth, Pteranodon (Toothless Wing) aren't among them.
- The Unfavorite: Petrie is well loved by his mother, but is often the target of the ire of his other siblings, particularly in Great Day of the Flyers where Petrie's inability to fly in formation causes all of his brothers and sisters to crash.
- 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.
- Vocal Evolution: His voice has become much higher and squeakier as the sequels have progressed.
- You No Take Candle: He rarely uses the pronoun I and instead prefers Me. He also usually uses No in place of Dont, and instead of using verbs in the present progressive tense hell use the infinitive, such as saying Petrie need help instead of Petrie needs help.
Appears in all fourteen films and the TV series.
- Absentee Actor: He doesn't appear in the final episode of the TV series.
- Big Brother Instinct: A unique case of a younger sibling having this.
- Big Eater: This and his speechlessness being his signature traits.
- Big Little Brother: To Ducky, although it's justified because they're different species. Ironically, she'll probably be taller than him when they grow up.
- Dumb Muscle: In the first film, due to Cera's attitude and the others' small height, Littlefoot usually ends up directing him to help with most physical tasks.
- Establishing Character Moment: Moments after hatching, he eats the tall grass that was surrounding his egg, instantly showing that he has a big appetite.
- Even the Dog Is Ashamed: Well, not quite dog-like or even a pet, but these still count.
- This is his reaction to Littlefoot and Cera's fight in the first film.
- In Invasion of the Tinysauruses, he is just as angry at Littlefoot as the rest of his friends are for lying to them about the Tinysauruses destroying the tree-sweet tree. Afterwards, he agrees with Ducky when she calls out Petrie on his hypocrisy in scolding them for being mad at Littlefoot, that he soon regrets as the others (making this a case where even the dog/dinosaur is ashamed of himself).
- In "The Amazing Threehorn Girl", he is just as upset with Cera as everyone else is after she confesses that she lied about saving the Great Valley from the Belly Draggers, sadly walking out on her.
- He shows his disapproval for Shorty's poor leadership skills like the Gang sans Littlefoot in "The Big Longneck Test", even looking angry for a split-second.
- In Journey of the Brave, he is appalled at Littlefoot as much as his friends (except for Chomper and Ruby, who tag along with Mr. Threehorn and Grandpa Longneck to try to find them) are for lashing out at them.
- Gentle Giant: His title is "gentle giant Spike" but he's only this to the characters that are smaller than him.
- 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.
- Mellow Fellow: He's the least energetic and most laid back of the gang, often outright ignoring anything around him that would distract him from his favorite activities of eating and relaxing. He himself seems to wish his friends exhibited this trope more often instead of always running off to go on dangerous adventures.
- Not So Stoic: In Invasion of the Tinysauruses, he breaks down in Ocular Gushers along with Ducky and Petrie over remorse for dismissing Littlefoot in anger.
- Oblivious Adoption: Deals with issues related to this trope in The Big Freeze.
- O.O.C. Is Serious Business: Spike is an elective mute: he can talk, but chooses not to, even when it's very inconvenient. The only times he's ever seen speaking are in life-or-death situations.
- 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. He nevertheless is loyal to them no matter what decision they all decide to make
- 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.
- Younger Than He Looks: He is actually the youngest of the original five due to not being born until halfway through the first movie.
Appears in films two, five, fourteen, and every episode of the TV series.

- Adorably Precocious Child: Especially evident in 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.
- The Baby of the Bunch: He was quite literally a baby in his first appearance, and remains the youngest and least worldly of the gang by the time of the TV show, which is why his parents sent him to the valley with someone to watch out for him: Ruby.
- Bad Liar: When he and Ruby are suspected of being in the area, he actually shouts from their hiding spot:Chomper: "I don't know what you mean! We're not here!"
- Big Brother Worship: While not his brother per se, he does seem to look up to Littlefoot as a big brother figure in his life and at times seems to cling to him for protection when he's scared or threatened.
- Break Out Character: Definitely the most popular and well known 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'.
- The Cutie: His eagerness, sweetness, and innocence make him this once he becomes a permanent member of the gang by the TV series, sharing the role with Ducky.
- 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.
- Doesn't Trust Those Guys: He's a frequent victim of this trope. While the Great Valley seems to have largely accepted that hes not like other sharpteeth, not everyone is entirely comfortable having him around. Several adults refuse to let him near their children, and some kids are still scared to death whenever he gets too closeincluding Petries own siblings.
- 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.
- Four-Fingered Hands: In his original appearance Chomper was correctly depicted with two claws on each hand, while in the fifth film, fourteenth film, and the TV series he gained a thumb.
- Guest-Star Party Member: In both Great Valley Adventure and Mysterious Island. In the TV series and Journey of the Brave he graduates to a Sixth Ranger.
- 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 still seem vulnerable to feeling like the odd one out.
- Man Bites Man: 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.
- 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 of 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: He's a member of the most feared and ferocious race of creatures in the Land Before Time world— one of the same blood that killed Littlefoot's mother and nearly killed Littlefoot himself. And yet, he's one of the sweetest and most gentle characters in the entire franchise (assuming you're not an insect).
- The Nose Knows: Chomper's incredible sense of smell comes in handy in both the TV series and Journey of the Brave, both for finding lost members of the gang and detecting oncoming threats.
- 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.
- Orc Raised by Elves: Carnivore raised by herbivores, specifically. Even though it was only for the first few days of his life, it's had a considerable impact on him.
- Out of Focus: In Journey of the Brave. Gets left out of the rescue mission, yet surprisingly this is not treated as an issue.
- 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. It makes sense that Chomper has red eyes, he inherited them from his parents.
- Ridiculously Cute Critter: In every appearance, but most obviously in the first one.
- Sixth Ranger: In animated series and all films beyond The Wisdom of Friends.
- Super Gullible: He's young with a very trusting heart and a gentle dispostion, which makes him easy to fool. Mr. Threehorn and Cera in particular delight in terrifying him with untrue stories.
- Token Heroic Orc: Or rather Token Heroic Sharptooth—the only truly decent and friendly one in the series.
- 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.
- You Can Talk?: Chomper was a silent character in "The Great Valley Adventure", as he had only just hatched. The gang is surprised to hear him speak to them when they reunite in "The Mysterious Island", and in the TV show Chomper constantly hears this reaction whenever he's introduced to a new character.
Appears or is mentioned in every TV episode, as well as film fourteen.
- Voiced by:
- Breakout Character: She is the first and only character that was introduced outside of the films to later appear in one, having first appeared in the TV series and later making her film debut in Journey of the Brave.
- Captain Obvious: Like a prehistoric Yogi Berra, she'll often speak aloud usually unspoken and implicit information to make a point about something.Ruby: "Well... the more you're mad, the less you're happy."
- Cloud Cuckoo Lander: Her strange way of speaking produces both thoughtful lines that demonstrates wisdom beyond her years and enigmatic oddities that leave her friends (and the audience) blinking in confusion.Ruby: "I'm right here... Of course, I'm always "here", and "here" is where ever I am."
- Cuckoosnarker: She's usually gentle about it, but her speaking style allows her plenty of opportunities for snarky comments.Ruby: "After all, talking about Cera is one of Cera's favorite things to talk about."
- Cool Big Sis: Ruby is the oldest of the kids and goes between this and Team Mom, especially for Chomper.
- Deadpan Snarker: Not nearly as much as Cera, but she has her moments when she gets annoyed.
- Department of Redundancy Department: Often. See Verbal Tic.
- Eccentric Mentor: As the eldest, she's this to the entire group at one point or another, but especially to Chomper. Often paired with her Cloud Cuckoo Lander way of speaking when she gives advice.Ruby: "You have to take the good with the bad... or else you can't take anything at all!"
- Nice Girl: She's always looking out for the group, and she always comforts Chomper when he's upset.
- Only Sane Woman: Along with Littlefoot, she's one of the most level-headed of the gang.
- Out of Focus: In Journey of the Brave. Gets left out of the rescue mission, yet surprisingly this is not treated as an issue.
- 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.
- Proverbial Wisdom: Due to her strange speech patterns, many things she says sound like a proverb or a koan.
- 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: She and Chomper are both introduced as new additions to the gang in the TV series, although unlike Chomper Ruby had no prior appearances in the series.
- Stock Animal Diet: For once in Dinosaur Media, averted. You'd expect her to eat eggs since she's an ''Oviraptor, but she doesn't and is more realistically an omnivore instead.
- Tomboy and Girly Girl: Girly Girl to Cera's Tomboy. (One of two)
- Vegetarian Carnivore: 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.
- 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.
- You Can't Go Home Again: Being Chomper's guardian has a heavy personal price: Ruby is forced to be away from her family in the Mysterious Beyond, and can't often visit them due to the risk of running into Red Claw. Two TV episodes focus on her feelings of homesickness and longing to be with her parents.
