Spike (a.k.a. Gentle Giant Spike, as he is called on the official site, and referred to as by fans) is one of the original five main characters in the Land Before Time films and television series. He is a Stegosaurus, which is referred to as a "Spiketail" in the films and TV series. He is most well-known for his laconic behaviour; only having uttered a couple of words throughout the series' run, and for his large appetite. Spike is raised by main-character Ducky's family, since his family was lost at the time of his birth, and possibly deceased. Best friends with his foster sister, Spike is usually listed in fifth place of the main characters, after Littlefoot, Cera, Ducky and Petrie, but is sometimes listed in third place, after Cera and before Ducky. Despite being well received by critics of the films, and being a favourite of director Don Bluth during the production of the original The Land Before Time, the character's cultural impact has been considerably small.
In the LBT-The First Humans, While Michael, Littlefoot and the gang search for the red emerald in the crater, Spike puts on a strange ring on his neck. But when Michael turned it on, Spike could speak!
