Chessmaster Hex is an elderly man debuting in Session 14. He is over 90 years old and is quite skilled at the game chess. He admits that Ed was one of the greatest opponents he has ever played and appears to pass away after playing her for a week. He appears to be the main antagonist in the episode he debuts in, but he forgot about his evil scheme that was planned 50 years before. He isn't very good at remembering things other than chess.
