Ozai's personal airship

Fire Lord Ozai's Personal Airship is an enormous Fire Nation Air Force airship used by Fire Lord Ozai.

Crew
The crew, along with the inside of the ship, was never seen, but it is almost certain that it was piloted by Royal Guards and engineers like the rest of the fleet.

Design
The ship was designed after a standard Fire Nation Airship, but was much larger. On the front was a golden phenix instead of a bronze dragon head that the other ships had. The ship also had walkways on it's underbelly where Firebenders stood and burned enemy targets.

History
The ship was first made a while after the Battle of the Northern Air Temple. The battle was a loss for the Fire Nation, but afterwards an experimental War Balloon, made by the Mechanist, was captured. It was used for some time but eventually it was outdated and larger airships replaced it.

Ozai's airship was made shortly before the final battle where Fire Lord Ozai and Avatar Aang faced off. Before that, his airship was constructed at a secret island off coast of the Earth Kingdom. In episode "Sozin's Comet Part 4: Avatar Aang", when the Fleet was departing the island, Sokka, Toph, and Suki arrived and managed to jump onto one of the regular airships, which was used to destroy a small part of the fleet. At some point in the battle this airship was hijacked and was used to destroy another part of the fleet.

Only one airship survived the battle, but it wasn't Ozai's.
