The Triceratops is an enemy found in The Pre-History Channel in Gex: Enter the Gecko. This dino is a powerful enemy that attacks by goring with it's horn. The only to kill it is by attacking it's sides. Attacking it from the front does nothing.
Unlike the name states it has a unicorn horn, a predatory Dinosaurs mouth, and Spikes on it's back it is more of a creation of Rez.
