The characters have more than a few passing similarities, it must be said. Both are insane (Kefka, due to the magitek trials, Deathwing due to Old God whispers, possible Demon Soul corruption), both just want to destroy the world for the sake of destroying the world, both have actually caused a cataclysmic event. Both have held possession of a magical artifact containing all the energies of magical beings of their world (Kefka=espers, Deathwing = Dragons). Both were initially trusted members of their groups, but fatally betrayed them (Kefka assassinated the emperor, Deathwing all but exterminated the blue dragon race). *tongue placed firmly in cheek* So the question is, who reckons the developers at Blizz were playing FFVI during the time they were pitching ideas for a new expansion
