Chuck's Reviews Transformers Rise of the Beasts Battle Masters Optimus Primal
 

One of the best releases under the ROTB line has been the Beast Battle Masters. It's fun to have small representations of the classic beast Transformers that transform into weapons for the larger robots. With Optimus Primal for example you can have some inception level displays going on. The Optimus Primal Battle Master is a great looking Gorilla, I really appreciate the attention to detail of the curved back and the ball-jointed head, that allows the figure in beast mode to look forward. Transformation is simple and gun mode comes together solidly. If you see it on shelves it's worth the purchase.
