Chuck's Reviews Transformers Reactivate Optimus Prime
 

Out of the four figures across the two Reactivate sets Optimus Prime is the best. That's not to say the others are bad, but Prime delivers on all points. Robot and Vehicle mode takes the Evergreen design and beefs it up while the transformation is involved but not overly complex. This is one of the better Prime figures we've gotten in a while and it makes the set with Soundwave the one to buy.
