While we still haven't seen what Dinobots leader Grimlock will look on screen in Michael Bay's latest franchise sequel Transformers: Age of Extinction, we have seen quite a few pieces of promo art and merchandise that tease this anticipated character hitting the big screen for the first time ever this summer. Hopefully, this Sunday's Super Bowl TV Spot will give us our first look at the giant robot in action, but until then, we'll have to settle for Grimlock on a backpack in new merchandising photos that have just been discovered. Also included is a look at Bumblebee in robot mode as he has been redesigned for this fourth chapter of the saga.
