Oh there it is, on the driver side!
Robot Mode is pretty neat too, even though I am a bit tired of the "Faux-Grill-Transform-Technique". Otherwise known as; his Torso turns to hide the vehicle grill behind his back, so that a more trimmed down grill version appears up front. I like my Prime with a square front.
This toy also begs for a matching mini trailer. Hasbro needs to release a million missing trailers now. It would be nice to bump him up in size just a bit too, as he stands about the same height as the other mini Autobots. Besides that, he is a wonderful miniature version of a Generation One Optimus Prime.
