Chuck's Reviews Transformers Robots In Disguise Combiner Force Activator Optimus Prime
 

Usually Optimus Prime is a wave 1 or 2 figure due to the name recognition so I was surprised to find it released later in the Activators sub line. Transformation is inventive and I really enjoy the armored truck mode and how everything opens. I feel that Prime's partner, Hi-Test is the best minicon released thus far, both its tank and gun modes are solid. Definitely worth a purchase.
