Leader of Dinobots and loyal subject to Autobot! The tough Grimlock transforms himself from robot to steel apex predator Tyrannosaurus Rex. This Hasbro version of Grimlock from Fall of Cybertron - Voyager was bought for my son at the time when he was fond of dinosaurs. I personally think that it is well designed and I have seen people customised theirs, by dry brushing to make it look even more realistically metallic.
Armed with melee weapons such as the sword and shield give the toy a medieval feel out off its futuristic design. In robot mode, Grimlock looks muscular with large chest and huge arms. Grimlock also looks amazing in dinosaur mode, just that the tail seems kind of thick. Last but not least the toy comes with gimmicks like battery operated glowing eyes and mouth as well as Tyrannosaurus chomping jaw mechanism.
