In a world filled with anthropomorphic dinosaurs, the five brothers—blue Bernie, pink Bruno, green Bubba, yellow Buck, and purple Bugsy—are born with unique abilities that they use to combat crime. Each sibling's power is tied to a specific body part: Bernie relies on his legs, Bruno on his arms, Bubba on his tail, Buck on his mouth and teeth, and Bugsy on his telekinetic eyes. Together, they ride out in their Rexmobile to take on “Big Boss” Graves, the crime lord of Rep City, along with his evil syndicate, The Corporation. Their younger sister Ginger is a member of their singing group, yet she remains unaware of her brothers' double lives.
