Transformers Construct Bots Grimlock and Optimus Prime Age of Extinction
Construct Bots are one of those toys that seem to fill up the shelves and never go anywhere, but sometimes they are actually kind of fun to pick one up. They have pretty good size to them, and are more durable than your regular Transformer.
Grimlock and Optimus Prime are a good duo to get, like in the new movie Age of Extinction, Prime does some Grimlock riding. They do this pretty good in toy form. Grimlock has both good robot and dinosaur forms as well (usually the alternate forms are pretty bad).
