The Tyrannosaurus Rex is arguably the pinnacle of the Dino-Riders toy line. For its time, this thing was a dinosaur fan’s dream come true. The set was huge and contained a lot of pieces that took quite some time to put together. The T-Rex retailed for $50 and although pretty steep for the average kid back in the day, it was definitely worth it. The T-Rex was the largest toy in the Dino-Rider line until the 2nd Series release of the Brontosaurus. The T-Rex also had motorized walking action that was powered by a D battery and assisted with small wheels on its feet. This feature would later be removed when it was re-released as part of the Smithsonian Institution line. The T-Rex included three figures, Krulos, Bitor and Cobrus, and the color of their outfits were actually somewhat coordinated. Despite it large size and awesome artillery, the T-Rex still left something to be desired. In perhaps the most disappointing use of the “colors may vary” disclaimer, Tyco released the T-Rex in a dark gray and greenish color instead of the advertised bright green and orange. It was really unfortunate because throughout the entire cartoon series, the T-Rex was always depicted as green and orange. The pre-production photos that advertised the T-Rex also depicted a green and orange color, which looked infinitely cooler than the final production model. But anyway, the T-Rex was still the coolest thing out there and still remains an awesome piece to this day.
