Azula (Bad Ending)

The world lay in ruins. Fire Lord Ozai's conquest was complete, his armies having crushed the last remnants of resistance. The Earth Kingdom was in flames, the Water Tribes were subjugated, and the Air Nomads were long extinct. The Avatar, the only hope for balance, had failed. Ozai had crowned himself Phoenix King, ruler of the world, and Azula, his daughter, had been named the new Fire Lord, the enforcer of his will. Bad ending, as in bad for the Gaang(how the show would've realistically ended)
