Mr. T-Rex is Galapagos's best soldier. He is a Tyrannosaurus who is based on (and voiced by) Mr. T. T-Rex is clearly a parody of Mr. T's characters Clubber Lang from Rocky III & B. A. Baracus from The A-Team, even saying "I pity the fool" and calling the Thunderlizards "fools" or "suckas." His anger frequently gets him into trouble resulting in the Thunderlizards having to save him. His two recruits are Nate the Dragon, a Velociraptor that uses a Bo staff and is clearly based on Bruce Lee, and El Gordo, a Spanish-like Ceratosaurus with the ability to use camouflage by putting any type of plant on his body
