Prince Zuko challenges Fire Lord Azula to an Agni Kai during the passing of Sozin’s Comet. 🍦

Fire-bender’s usually draw their strength from the sun, but the passing comet gifted Zuko and Azula otherworldly power during their duel.

An Agni Kai is a centuries old Fire Nation tradition, used as a method to settle conflicts and disputes. It is a fight to the death, or until one bender critically burns the other.
