19. Czar Dragon/Zombone

Series: Mario RPG/Final Fantasy Series
First Appearance: Final Fantasy VI 

Czar Dragon was the holder of the 6th star in Super Mario RPG. Though the Axem Rangers took the star after defeating this dragon, he is the rightful holder. Just when you thought you were finished with Czar Dragon, he dropped into the lava and reemerged as Zombone, even stronger and even more of a challenge.

You would have had a chance to face Czar Dragon two years prior to Mario RPG if he wasn’t taken out of Final Fantasy VI. Let’s thank the fanboys for finding that boss fight.
