Leading up the Assembly faction is odd-ball scientist Doctor Overbuild. Originally called Doctor Brickmaster, he was supposed to be a solid mix of Doc Emmett Brown from Back to the Future and Egon Spangler from Ghostbusters. Later, we moved him in to a much more tech feel to get cooler accessories, also taking some cues from Spiderman's Doc Oc.

The tech re-design. We ultimately eliminated the two lower mechanical arms due to technical limitations. The colors of the Assembly faction also switched from a red theme to the final orange. This sheet also shows plans for various head accessories for Doc.
