Five-Man Band: Formerly this, but gained two members in the TV show.
Grief Song: 'Always There' 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.
In the final verse, Littlefoot sings about his mother.
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), but the trope holds true in the literal sense: at several points they've actually butted heads.
Kid Heroes: 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.
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.
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.
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.
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.
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
"Threehorns never play with Longnecks!"
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.
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.
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.
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.
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.
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.
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.
Petrie - Pteranodon
"You've got a nice flat head, Flat Head."
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.
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.
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.
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.
"Dear, sweet, Littlefoot, do you remember the way to the Great Valley?"
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.
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.
Two 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 mother and father of Mama Longneck. 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.
"Come Cera, three horns never play with long necks."
An aggressive male Triceratops with deep seated prejudice against dinosaurs other than his own kind. He's Cera and Patricia'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.
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.
"It's nobody's fault. The great circle of life has begun. But see, not all of us arrive together at the end."
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.
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.
Declaration of Protection: He and Ducky get trapped on a rock out crop in the middle of a ravine. With a velociraptor. 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 Allosaurid's tail (to protect his friends) in the fifth movie.
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.
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.
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.
Bad Ass: 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.
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.
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.
Villain Song: 'When You're Big', a possible contender for the best villain song in the series.
Ali - Apatosaurus
"It takes all sorts to make our world."
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.
Walking the Earth: Her herd is migratory, after their homeland was ruined by constant rain and floods.
Old One – Apatosaurus
The leader of a group of wandering longnecks called the farwalkers, she brings word of the outside world to the Great Valley and identifies a sickness that has overtaken Littlefoot's grandfather.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.
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
Ichy-"I do all the REAL work around here. I'm the eyes!" Dil-"So? I'm the teeth!"
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.
Somewhere, a Palaeontologist Is Crying: 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.
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.
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.
The Nameless: 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
"Have it your way, kid."
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.
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'.
"Petrie, I'm heartbroken. Didn't you recognise your dear old uncle?"
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.
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.
Past Sins: 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.
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 Rhamphorhynchus
Two conniving pterosaurs that associate themselves with Petrie's uncle Pterano. However, they seem to have plans all their own...Appears in film seven only.
A mysterious male and female Gallimimus who talk in riddles and seem to posses uncommonly advanced knowledge about the world. Their current whereabouts (if they're even still on Earth) are unknown.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.
An old teacher who's responsible for giving young dinosaurs in the Great Valley their primary education. He lives alone in the Great Valley; it is unknown if he continues to teach or not.Appears in film eight and several TV episodes.
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.
Tippy - Stegosaurus
Appears in film eight and one episode of the TV series.
An energetic Opthalmosaurus who befriends Littlefoot after he becomes trapped in the floodwaters of the Great Valley. He lives in the Big Water with the rest of his family.Appears in film nine, makes cameos in films eleven 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.
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.
A voracious carnivore from the sea, this swimming sharptooth is a long way from home to be sure, but he won't let that get in the way of a good meal.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.
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.
"Your mother and I knew we were going to have a hatchling."
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.
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.
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.
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.
Shorty - Brachiosaurus
An orphaned, troubled young Brachiosaurus who travels with Bron's herd. Bron later officially adopts him, making him Littlefoot's adopted brother. He lives a nomadic life with his adopted father.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.
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 Patricia. 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.
Evil Stepmother: Averted. Tria has shown herself to be a good stepmother who loves and watches out for her stepdaughter Cera.
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.
Science Marches On: Averted. They don't bear even a remote resemblance to what Beipeiaosaurus actually looked like.
Technically speaking, the Yellow Bellies resemble generic therizinosaurs. Very, very cartooninised therizinosaurs. When they were concepted, there wasn't a lot of Beipiaosaurus material to go by, so their appearence wasn't so offensively backwards.
The Scrappy: The Yellow Bellies are the only characters that seem to be universally disliked by fans.
The television series
Ruby - Oviraptor
"Hello, my friends, my friends hello!"
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.
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.
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.
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.
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.
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.
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.
