Chuck's Reviews Transformers Rise of the Beasts Smash Changers Rhinox
 

Out of the four Smash Changers we've gotten, Rhinox is the best. Combining the limited articulation of Optimus Prime, with the overall fun of Optimus Primal, Rhinox rocks! The cherry on this sundae is the removable Rhino head that can be used as a weapon or shield. You could wait for a sale to take some of the edge off this price, but since it's a late-line release you might be playing chicken with finding it.
