Rick is a cowboy from the American West, skilled with a lasso and often traveling by horseback. After his parents' deaths, he lives with his grandfather and becomes the protector of two fossils. These fossils are later revealed to belong to two of the three Cerazaur Brothers: Dino Centro, Dino Toro, and Dino Styraco. Rick possesses the unique Dino Dagger, essential for restoring the fossilized Dino Knights' strength and vitality. This connection leads to the Cerazaur Brothers' awakening and fosters a profound bond, resulting in Rick being recognized as their "fourth brother."

Rick participates in the Cerazaur Brothers' combined form, Dino Triblades, activated by the command "Triblade Fusion! Integrate!" This fusion wields the Triple Fossil Star Sword. During a confrontation at the Ninja Castle, a trap set by Dark Dragon targeting Styraco results in Rick's capture. To save Rick, Styraco sacrifices his own life energy. Rick and the other Cerazaur Brothers later reverse this sacrifice, rescuing Styraco. In recognition of Rick's loyalty and courage, the Cerazaur Brothers present him with a scroll signifying his deep understanding of Bushido principles.

Living in the rural landscapes of New Mexico, Rick has relatively infrequent interactions with the series' other primary human characters. Initially distant and reluctant to involve others in Cerazaur matters, his perspective shifts after a critical intervention aiding Tyranno against Gigano Dragon. This act solidifies his role as a recurring ally, though he maintains a degree of reserve within these alliances and his relationship with the Cerazaur Brothers. The loss of his parents, mentioned by his grandfather as part of his background establishing his living situation, is not revisited as a central plot point.
