Edward Nashton (Earth-78)

Edward "Eddie" Nashton is a self-help guru who claimed he survived from the Joker's games, becoming a media sensation through London by selling his story. However, Edward was a fraud, and he had never been part of one of the Joker's "experimentations", something only his best friend Foggy Nelson, and his lawyer Jennifer Walters knew (and that even his wife Karen Nashton was oblivious). His lies and undeserved fame led him to be captured and used in a series of real Joker games.
