While I have admittedly slowed down on the Kre-O stuff, it was fun revisiting it and frankly this Optimus was pretty cool. The toy is mostly in translucent blue and clear plastic with some solid white colored pieces. He's pretty dang sharp looking.
I had a hard time finding this version on the TFWiki, so I have no clue what they're actually called. They've had them at Dollar General for a while and I've just now gotten this one. Basically you get a Kreon with the parts to add on to make a more 'deluxe' figure. With all the parts added the figure has knees and elbows and stands a little taller. It's a neat little thing and I'm pretty tempted to get more now.
He could be a Henshin Cyborg as well I suppose, but my mind goes to Microman first. I've taken to calling him Microman Orion. A different helmet for the more 'deluxe' figure and he'd make a fine Acroyear. Now that I have essentially that Kre-O Micronaut I wished I had all those years ago, I really wish they would have made that line. The proportions are just right as is the sculpting. Oh well, at least I have a cool Optimus Prime.
