Grimlock

Grimlock is the name of several fictional characters in the Transformers universes. He is usually portrayed as a tough leader who turns into a mechanical dinosaur. In 2007, USA Today polled people as to which Transformer they want to appear in the next Transformers film; Grimlock came in tied for second with Devastator.[1]

Transformers: Generation 1
Grimlock is the most fearsome and powerful member of the Dinobots.[2] Grimlock can be cold, merciless and contemptuous of those he considers beneath him, such as human beings, and at times, even Autobot leader Optimus Prime himself, who Grimlock would gladly supplant as Autobot leader if he were able to, giving him a superiority complex as indicated by his Generation 1 tech specs. Nevertheless, he is a valiant warrior whose actions command respect from all who are witness to them, both friend and foe. One of his most distinguishing features is his famous speech impediment, resembling clichedcaveman speech, which leads him to shorten sentences and refer to himself constantly as "Me Grimlock", never "I" (i.e. "Me Grimlock no bozo! Me KING!") - the reason for this varies from depiction to depiction, with some making it the result of true mental limitations, and others vocal processor damage or a ruse Grimlock perpetrates to allow others to think of him as less intelligent than he actually is.

Grimlock is among the strongest of the Transformers, possibly an equal to, or even superior to Optimus Prime and Megatron in certain continuities. In Tyrannosaurus rexmode, his powerful jaws can snap virtually anything that comes between them - from steel cables to a Decepticon limb. He also can shoot an energy ray from his mouth. In robot mode, Grimlock wields an energo-sword, whose blade is sheathed in crackling energon and can slice a 2-foot-thick (0.61 m) concrete wall in one slash. He also uses a double-barreled, self-propelled rocket launcher. He is almost invulnerable in his Tyrannosaurus Rex mode as shown with his battle with Megatron due to Megatron's primary weapon, his arm-mounted fusion cannon having little or no effect on Grimlock.
