Czar Dragon

The Czar Dragon is the boss of the Barrel Volcano who also protects the sixth Star Piece in Super Mario RPG: Legend of the Seven Stars. He is a fire dragon, and as such, is a master of fire magic. However, he also knows as substantial number of earth magic spells, which he uses to attack his enemies. The Czar Dragon also knows the attack Water Blast (which seems strange, since he is made of fire; however, for some reason, Water Blast is an earth magic attack, not a water magic attack). After Mario and his party defeat the Czar Dragon, the monster immediately returns from the grave as the menacing Zombone.

The Czar Dragon looks similar to the Blargg enemies from Super Mario World. As such, it is rumored that the Czar Dragon is the king of the Blarggs. In fact, the word czar is an imperial Russian title that means emperor (literally Caesar).
