History Characters / TheLandBeforeTimeFirstFilm

* CarnivoreConfusion: He is a ''T. rex'' hunting sentient baby dinosaurs.

* FlatCharacter: In the movie he only serves as the scary T-Rex antagonist who tries to eat the protagonist and nothing more. His personality or motivations are not further explored. Averted in the novelization where some of the narration it's told by his point of view indication that he's a sadistic and vengeful predator with a SerialKiller instinct.

* LightningBruiser: Ridiculously tough for a big Tyrannosaurus, but if pissed off enough, he lunges ''so incredibly fast'' he can't control that speed; he dives over and plows through everything, just barely missing the heroes. He can even leap to great heights and distances, soaring over Littlefoot's mother, and leaping from bottom to top of a very tall cliff in ''seconds''.

* GutturalGrowler: Speaks with a very coarse, gruff voice.

* FantasticRacism: He doesn't think highly of dinosaurs other than his kind, and is especially prejudiced against longnecks. Seems to get along with Grandpa Longneck in the sequels well enough, however.

* SuperNotDrowningSkills: Shares this with other "swimmers" in this setting, and most notably demonstrated when she saved Spike in the eighth movie.

* OffModel: He’s drawn with an almost lavender color palette in the final scene of the original film.

* PinkGirlBlueBoy: In a glaring case of OffModel, she and her husband are incorrectly drawn like this in the final scene of the first film.

* AbsenteeActor: ''Journey Through The Mists'' is currently the only film in which he doesn’t appear.

* KnightOfCerebus: ''Oh yes.'' The movie is initially very light in its tone. Then he shows up and kills Littlefoot's mother. Anytime he does appear on screen for the rest of the movie the levity stops and the heartwarming atmosphere screeches to a abrupt halt. Part of what made the sequels LighterAndSofter is that they didn't have any villains nearly as dark as him.

* PinkGirlBlueBoy: 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.

* BadVibration: He introduces himself to Littlefoot and Cera with heavy footsteps that shake the ground beneath them.

* HistoricalBadassUpgrade: Compared to a real tyrannosaur. The real ''T. rex'' was certainly a tough animal, but needless to say it still wasn't anywhere near as strong or durable as Sharptooth is shown to be.

* MamaBear and PapaWolf: They are both quite protective of their grandson and will fight off dangerous predators to keep him safe.

!!!'''Voiced by:''' Creator/PatHingle

!!!'''Species:''' Swimmer (unspecified hadrosaur)

* KingOfTheDinosaurs: It's a ''Tyrannosaurus rex'' and it's the [[TheDreaded most feared dinosaur]] in the land. Even Littlefoot's mother can barely fend him off (and she paid her life for it), and his primary prey are young dinosaurs who could do nothing but run [[spoiler:until Littlefoot comes up with a plan to drown the monster into a deep watery pit with a giant boulder]].

* PapaWolf: While a GrumpyBear to begin with, nothing makes him angrier than threatening his family.

* {{Expy}}: Of Bambi's mom, from giving birth to a son at the beginning, [[HeroicSacrifice to dying while rescuing her son from one out get him.]]

!!!'''Voiced by:''' Burke Byrnes (original film) | John Ingle (''II'' to TV series) | George Ball (''XIV'')

* GrumpyBear: Is perpetually in a bad mood. Even his daughter states he's always mad.

* {{Jerkass}}: His defining trait is his stubborn, unfriendly exterior. He taught Cera her FantasticRacism in the first film, and he repeatedly caused trouble for all the other grown-ups in the sequels and the series.
* JerkWithAHeartOfGold: He genuinely loves his daughter despite all his other flaws. He also points out to Hyp’s father in ''The Time Of the Great Giving'' that yelling at one’s children only hurts them more than helps as he realized with his interactions with his daughter. In ''Secret of Saurus Rock'', he actually felt bad about upsetting Littlefoot by blaming Doc for their recent misfortune in the Great Valley, while also conceding that Doc seems to be a perfectly fine fellow but for seemingly being "bad luck."

* BewareTheNiceOnes: The two are the kindlest and gentlest Longnecks in the series... yet both are capable of kicking major Sharptooth ass (and, indeed, ''do just that'' in ''The Great Longneck Migration'') and the look on Grandpa Longneck's face as he slides in to save Littlefoot from a Sharptooth is terrifying! Also, if you insult their grandson they will ''not'' be happy.

* MamaBear: They are both quite protective of their grandson and will fight off dangerous predators to keep him safe.
