I had to do this when I seen the Incinerator at my Wal Mart. I originally just planned for a repaint with a new head not a Headmaster but ended up doing Highbrow and Gort. The hands came off of a SD Gundam Sandrock and were bored to fit the blade nubs. The hands can hold guns and the blades not to mention when the device is pulled on his back it spins the guns! I used one of the Minicons from Sideways for the head. I removed the covered mouth section and free sculpted the rest of his face in there. The face plate slides up to reveal his eyes. Painting was done with a Testors black base then fortress grey and Utrmarine blue for top colors. Robotics were done in chainmail silver. hope ya like 'em!
