While many people dismiss the Titan figure line as glorified shampoo bottles, the sales of the various figures show their popularity. Expanding upon the 6" and 12" assortments, Hasbro has decided to add a simple transformation to the figures creating Titan Changers. The quality of plastic on Optimus Prime is nice with a metallic, marbleized finish. Transformation is simple but fun, resulting in truck mode that can roll easily. Obviously most adult collectors will pass on this line but for younger fans, or those looking to keep their hands busy, Optimus Prime is a fun figure.
