I got it from Hong Kong off Ebay, packaged and with both the catalogue and card insert. Slightly worryingly the instructions were photocopied though......
Vehicle Mode: Mainly dark green truck with the most massive Decepticon logo you have ever seen on the back in purple. Spark crystal in the bumper which - as someone observed at Hubday - doesn't fit the Energon Stars with the basics. Truck back tips back slightly, 2 minicon posts on the bit overhanging the cab.
Hyper Vehicle Mode: Fold the overhanging flap back - revealing 2 more minicon posts - and rotate out to the side revealing a huge ( 4 x 2 ) missile array. The bottom 4 missiles are active and can be fired by tiny buttons in the back of the truck.
Transformation: Separate the legs from the back of the truck, fold the feet up and origami the waist from behind the cab to lock in underneath it. More origami pulls the arms out from the cab, allowing the grill to rotate into the waist revealing the chest. Bend the truck/missile array back onto his back revealing the head.
Robot mode: still lots of green, but joined by some brown on the lower legs & upper arms, purple on the chest and transparent green on shoulders and forearms. Head looks very Rhinox..... in fact the whole toy screams Rhinox at you with it's green shades..... It's almost if the toyline has come full circle from Rhinox to Tankorr then (via the tank connection) to Armada Demolishor and then the Energon version of the same character. Hands can hold the Energon weapons the basics produce but like Snowcat he doesn't come with one. Some ankle, knees, bicep type joint above the knee, universal hips, 2 shoulder joints - one back and forth, the other to the side, a bicep joint and elbows on each side, plus a head on a jointed neck that allows for lots of poses.
Hyper Robot mode: Fold the chest forward a further 90 degrees, taking the head down on to the chest - here's where that neck is useful - and raising the missile pod onto the top of his body where it can be fired.
Overall: good bit of fun, but I'm preferring the Autobots and the combination gimmick
I got to play with Andy's Optimus Prime and Nick's Mega Zarak (Scorponok) at the weekend. Prime is nice, chunky and much better in the plastic than you think from the pictures. The interchangeable limbs are a good idea and work OK. However already owning a number of big Primes and being limited for space I'm going to pass on this till the UK release.
Scorps is smaller than you'd imagine, lots of annoying sounds that go off if you look at him wrong. Good scorpion, good robot - apart from the hands, something just isn't working right there even for a claw hand. Didn't see the jet. BBTS have them up for $30 at the moment which is a steal.
Demolishor was available in Superlink in Japan as SD-11 Iron Tread.
