Cera

Cera is the triceratops in Land Before Time. She was having a conflict with Littlefoot in the first film. 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.
