To Transform - swing the panelled halves of the doors to the sides, and fold out the fists, and then fold the arms down. Separate the back of the car down the middle and fold the entire back of the car under the front to form the legs. Fold the legs down, fold out the heel spurs and then open the panels on his legs to flip out the feet - quite similar to Energon Downshift IIRC. Fold back the car roof - which causes the head to pop up and the ears to pop out the side of the head. Yes once again Downshift is Wheeljack, especially in the head sculpt. The missiles launchers can then either be hand held or clip onto the shoulders.
The robot exposes two new plastic colours - black on the arms & feet and grey on the hands & upper legs. The robot's knees bend, plus there's a swivel below them, his hips are ball and socket joints, his shoulders move back & forth and (thanks to the TF) up to the sides and his elbow bends forwards. There is a neck joint but this is seriously impaired by the head being slightly recessed into the body - 1mm and there would be full movement. A bicep would have been nice too, as would a waist - lost due to the TF. His door shoulder pads make him as wide as he is tall and his chest is the car - the head sticks over the bonnet like G1 Prowl, with his eyes and Wheeljack ears But despite all this he's a really good robot - the green here isn't out of place making him look very militaristic with the big guns. For something that should look awful it's an excellent toy.
The original Big Daddy was a black Micromaster muscle car with some orange robot parts. It's use as a rename & recolour on this mould was an obvious with the black replacing the green and the orange replacing the grey (and being painted onto the head) The black & clear orange stay the same.
Great repaint. Worth having, and I'm sure the mould will be back again.
