Cera is the deuteragonist and primary female character in The Land Before Time franchise. She is also the secondary antagonist of The Land Before Time. She was voiced by Candace Hutson from The Land Before Time to Journey Through the Mists, after which her voice was provided by Anndi McAfee. She is a Triceratops, which is known as a "Threehorn" to the characters in the franchise. Cera's most recognizable trait is her bossy, skeptical and proud demeanor, which covers up her caring and sensitive side. As seen in The Wisdom of Friends and the television series, Cera can also have a fun-loving side if given proper stimulus first, the yellow bellies admiring her horn in the case of The Wisdom of Friends and Tria's secret mud pools in the case of the television series. She has a father named Daddy Topps, whose personality is quite similar to hers, but much more severe. In fact, it is very likely that she learned her gruff, stubborn, bossy, and sometimes just plain mean side from her father. Her biological mother has not been seen since the original movie, but as of the eleventh installment, 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 Daddy Topps. Cera is friends with the other six main characters of the franchise: Littlefoot, Ducky, Petrie, Spike, Chomper, and Ruby (that are Cera's friends), 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".
