TF: TF'ing to robot is easy. Getting back isn't so take a good look at where everything is first when you turn the beast over: His right arm (your left) ends in the right rear leg, the left arm (your right) ends in the head. The robot legs are bent up so that the inside of the leg runs along the edges of the robot's lower torso, with the lower legs bent as far behind these as possible. The shell is slotted on to the top and bottom of the robot torso. Got that ? If you get a new one please take a photo of how the legs are arranged there and keep it in a safe place. Better yet send on to me as I'm still not sure I've got it 100% right ! Onward: Fold back the beast legs that aren't attached to a robot arm. Fold out the robot legs, spin the lower legs round at the knees and fold down the toes and heel spurs. Fold the head out revealing the robot's left arm. Unclip the back beast armour and swing the front beast armour onto his left shoulder. Fold out the right arm, and then the hand. Position the back and tail along the right arm. Flip up and turn the head. Remove the weapon from within the tail and place in the robot's hand - it can function as an axe or a gun.
Robot has the standard BW articulation of ball joints at neck, knees, hips, shoulders and elbows. His feet and heel spurs bend up as part of the TF. There's a purple/pink Destron (Predacon) spark exposed in his chest. The robot has some balance issue due to all the beast clobber hanging off.
I quite like the toy in both modes. I just dread turning it back into a beast.
