You don't call on Grimlock when the problem you're trying to solve needs something to be fixed, but if solving the problem means something needs to be broken, then he's the perfect Autobot for the task! This 3.75"" articulated Transformers ReAction figure shows him in his most recognizable Dinobot form, a ferocious mechanical Tyrannosaurus Rex. He's of the mightiest and most iconic Autobots, so if you're not roaring in delight at the chance to add the Transformers ReAction figure of Grimlock to your collection it might be time you get tested for low levels of Cybertonium in your cerebral processing unit.
