This 80sTees.com exclusive Transformers t-shirt features an image of Grimlock in robot mode and transformed into a mechanical Tyrannosaurus. The discovery of dinosaur fossils inspired the Autobots to create the Dinobots strike squad. Grimlock was ruthless and powerful, and chosen as the leader of the Dinobots. In robot mode, Grimlock is dangerous with his energo-sword. Transformed, Grimlock is even more powerful and dangerous, as he can tear or bite enemies into pieces!
