So this thing was entirely based on me thinking of gears spinning really fast and grinding and heating up and creating fire and stuff, and wanted to be a little different. Motor Drive gives it immunity to Electric Moves, including the ever present Thunder Wave. The new moves are based on the overheating idea. Boost to defenses are useful with the change in type, and of course it is a physical attacker. Other possible abilities are Bulletproof, Flame Body and Turboblaze.
