Chuck's Reviews Transformers Studio Series Core Class Shockwave
 

The introduction of the Core Class to the Studio Series opens up the line to smaller-scale characters from the live-action movies like Wheelie and Brains. Of course, the first figure released is Shockwave. Don't forget, Core Class is also meant to be a cheaper price point to get named characters into people's hands. Shockwave is a cool figure, the transformation is fairly easy but as is the case when dealing with ball joints, the tightness of the joints can be a factor in how enjoyable the transformation is. Overall, Shockwave is a good figure and while I believe we will see a larger version at some point, this Core Class version can hold you over for the time being.
