This is a fully transformable Optimus Primal MOC made strictly from Hero Factory 2.0 parts. No partsforming here, and everything hold together pretty tight. Transformation is more complex than it looks, the torso does a lot of morphing and rearranging. Of course I would like to have used Surge's blue helmet, and I wish we had the hero head/feet and Nitroblast/Jetbug head in silver, but whatchagonnado.
EDIT: Here's a couple photos to illustrate proper (photoshopped) colors and the level of maneuverability in the spine of the ape mode.
EDIT: Here's a folder of images that I just uploaded to Flickr that should assist you in replicating this. Hope some people do.
