Cera

Cera (a.k.a. "Sweet but strong-willed Cera" or simply "Strong-willed Cera", as she is referred to as by fans, and on the official Land Before Time website), (voiced by Anndi McAfee) is the antagonist turned-dueteragoinst in The Land Before Time 12&3 and television series and a minor character in The Land Before Time sequels. She is a Triceratops, which is known as a "Threehorn" to the characters in the films and TV show. Cera's most recognizable character trait is her bossy, skeptical and proud demeanor, which covers up a more caring and sensitive side. She has a father named Topps, who's personality is quite similar to hers, but much more severe. Her mother has not been seen since the original movie, but as of the end of the eleventh installment, The Land Before Time XI: Invasion of the Tinysauruses, she has a stepmother named Tria. She also has numerous siblings, but the only prominent one is her half-sister, Tricia, the daughter of Tria and Topps. Cera is friends with the other six main characters in the films and TV series, Littlefoot, Ducky, Petrie, Spike, Chomper, and Ruby, although her strongest friendships appear to be with Littlefoot and Ducky. In most instances in which the main characters are listed in order, she is placed second, after Littlefoot. The character has come under a comfortable public reception, and has spawned plenty of merchandise, along with being mentioned in many other media. Similarly to the character Ducky, there has been confusion over Cera's species, although it has not been labelled incorrectly as often as Ducky's. The spelling of her name, however, has suffered from much more dispute. She is most commonly mistaken to be a Monoclonius, while her name is frequently mistaken to be spelled as "Sarah".
