GRIMLOCK keeps a collection of the parts he's torn off his DECEPTICON enemies. His super-thick ultramantium skin - in both robot and dinosaur mode - is coated in energy-absorbing materials, making him nearly impervious to damage. There are many who might say much the same thing about his mind. He is actually quite smart, but a programming flaw in his speech centers gives him only the most basic communications skills. He dislikes the weak, but is dedicated to the protection of those he views as lesser creatures. The only thing he hates more than weakness, in fact, is those who exploit the weak.

Amazing robot figure changes into detailed dino beast and back! Figure features a guardian blaster that attaches to T. Rex mode and a tail that becomes a smashing whip!
