The Arcade quotes of his opponent seem to indicate that Potemkin is a robot....is this an in-joke or for real?
Sin's win quote in particular seems quite sincere, where he shouts at him to come down and fight him for real.
I also read this about the meaning of Potemkin (wiki):
"The phrase "Potemkin village" (also "Potyomkin village", derived from the Russian: Потёмкинские деревни, Potyomkinskiye derevni) was originally used to describe a fake village, built only to impress".
Maybe I'm the only who found this interesting, and I apologise if speculation is not welcome here.
