Dino-Riders
The most notable toy from this series was the "Brontosaurus", which was the largest toy in the entire range, measuring 34 inches long and 15 inches tall. In an effort to keep costs down, Tyco had to abandon several features that were originally intended to be part of the figure. These included motorized walking action, four figures instead of three, and an entirely different weapons system.
