Chuck Builds Transformers Kreo Age of Extinction Optimus Prime and Grimlock
 

This is a quirky little build that was given out a Toys R Us' a few Saturdays ago as part of a special Kre-O event. I was surprised that they used the Cityvile body mold for Prime but it kinda makes sense due to the size of Grimlock. It's going for some big money on the aftermarket so unless you "gotta catch them all" this set can be avoided.
