Artwork of "Dueler X" aka Mog from Final Fantasy Fables: Chocobo Tales. A recurring character in the Chocobo series, Mog has delusions of grandeur and is a friendly rival to Chocobo, traveling with him but always looking to steal treasure and glory for himself. In Chocobo Tales under his "Dueler X" disguise, Mog teaches Chocobo about pop-up duels. He reappears in Final Fantasy Fables: Chocobo's Dungeon using the similar alias "Dungeon Hero X". In both games everyone except Chocobo realizes who Mog really is, but he refuses to admit it.
