Dr. Eyepatch

Dr Eyepatch is a mystery wrapped around an enigma poorly taped to the side of a time bomb. That is to say, he is a difficult character to summarize. The most I can say on his behalf is that he is that 1: most likely the creator, or at least took part in the creation, to all of the robots made at King's Idea Laboratory including Tetsuko and 2: He most likely has more influence on the world than he lets on, maybe even more than the president.
