A Thomas Edison
The ideal form of the world (America) that Edison's inventions led to. He can mass produce a nearly infinite number of soldiers to act as his subordinates. There seems to be some sort of balance being kept, but its being done by someone or something that is not around him. The resources being consumed are from a place unrelated to America, so he has no qualms with exploiting it fully.[1]
