Got this guy along with Rodimus Prime last night... Transformed him this morning, and some thoughts... Grimlock's T-Rex mode is just soooo bad. Well, everything from his waist down anyway as those combiner ports just make his tail and legs look weird. Not to mention that clear plastic for the robot chest/lower dino. I forsee a lot of broken PotP Grimlocks in the years to come cause of that flimsy clear plastic. Still, we got a new Grimlock...we're getting new Dinobots in G1 style again... Now the wait for PotP Sludge and Snarl to come out... Not for the combiner mode, just to have a complete set of Dinobots again. Could care less about Volcanus.
