Fire Nation Prince Azulon II aka "Azule"

(Basically I took Azula, and made her into a bratty pretty boy twink)

Azule is the Crown Prince of the Fire Nation, Son of Fire Lord Ozia and Fire Consort Urso.

He is the heir to the Fire Nation throne after his older sister Zuka was banished by their father.
