Thanks to the Caves Of Narshe website we found out that in the code of Final Fantasy 6 is possible to find an unused enemy, called “Czar Dragon”. An unused dialogue related to this monster is hidden too:
“Mwa, ha, ha…. Humans and their desires! I’m free at last! I bring you destruction… I bring you terror… I am Czar! Prepare yourselves!”
Also as Dragonsbrethren and Deathlike2 from the Slick Productions Forum has noted, some beta screenshots shown that Biggs and Wedge were named Leo and Banon, and Maduin was frozen in ice instead of Tritoch. The pictures also show that the fight/attack command was available when the M-tek status is applied. There may not have been a Magitek status at this point in development, the armor could have just been for show, or it could be what’s giving them those high HP totals.
