Dino Styraco is a Styracosaurus and the eldest brother of the Cerazaur Brothers trio, completed by Dino Centro and Dino Toro. Discovered by their human guardian and ally, Rick, these three form the Dino Knights unit known as the Cerazaur Brothers. Dino Styraco commands the "Triblade Fusion! Integrate!" transformation, merging with his siblings to become the colossal Dino Triblades. In this combined form, he comprises the head, main torso, and legs, wielding the Triple Fossil Star Sword against their foes.

Individually, Dino Styraco battles the Dragozaurs using his Styraco Sword of Stealth. His role as the oldest brother naturally emphasizes leadership within the trio. The Cerazaur Brothers, alongside Rick, occasionally undertook missions independent of the other Dino Knights and humans, starring in dedicated episodes focused on their exploits.
