TFAnimated Grimlock

Grimlock, Dinobot Leader

Grimlock (グリムロック, Gurimurokku) is a Tyrannosaurus rex in charge of a small, three-mech group of dinosaur transformers known as the Dinobots. Born from a fusion of Earth and Cybertronian technology, with some AllSpark intervention thrown in, he's a force to be reckoned with. A little short on brains (at first he didn't actually realise he was a Transformer) and a lot short on temper, Grimlock's answer to a problem is usually the simplest: squash it, slash it, bite it, burn it, or eat it.

Physically, Grimlock is one of the most powerful Transformers, with enough brute strength to give even the likes of Megatron pause for thought. In his beast mode, his powerful jaws and flame breath give him excellent short- and long-range combat abilities, while his flaming sword is an effective weapon in robot mode. Factor in his temper, and facing Grimlock can be a terrifying experience.

Currently, Grimlock and his fellow Dinobots are living on an island in Lake Erie, hidden there by Prowl and Bulkhead from the rest of the world. But don't think he's not willing to come to the mainland, find the biggest 'Con around and feed 'em their own chassis after he's eaten his fill of it. After all, Grimlock is a real beast.

Appearance & BiographyEdit

Voice actor: David Kaye (English), Keiji Fujiwara (Japanese)

Grimlock more than lives up to the reputation of his Tyrannosaurus Rex mode. Ill-tempered, powerful, and always ready for a fight, he loves to throw his weight around. He likes the way the ground shakes as he stomps around, and the way people scatter when he roars. He's happiest on Dinobot Island, where he can stomp and roar to his Spark's content, shattering trees with his tail, and breathing jets of flame into the sky. Every once in a while, though, he prefers to find the biggest, most powerful Decepticon he can, and smash its chassis to pieces.

While he has no Cybertronian vehicle mode, he does have the beast mode of a Tyrannosaurus Rex.

Weapons and AbilitesEdit

Aside from his brute strength, Grimlock can shoot superheated flames from his mouth in beast mode. In robot mode, Grimlock carries a sword, whose blade can ignite into a sword of flames. "Predacons Rising" showed that Grimlock can also shoot these flames from his sword.

Grimlock has a simple personality though, and is quite primitive. He can be manipulated through his emotions, as Blackarachnia and Meltdown has demonstrated, variously using love and fear of pain to control the mighty Dinobot.
