Avatar‘s (the Last Airbender) history clash as the two biggest antagonists of the series compete against each other. Azula is the daughter of Ozai, the Fire Nation King (at the time). She’s a firebending prodigy, sadistic, manipulative, and obsessed with power. Over 100 years later, Amon (making his first appearance on the pile) is the leader of the Equalists, a group of Chi-Blockers whose ultimate goal is to create equality by ridding the world of benders. Despite being a non-bender, he has shown to be a very skilled, agile and nimble fighter.
Azula is before the Boiling Rock incident, so she is sane. They are each equipped with their standard load out. And the fight takes place in an empty Metropolis (from DC Comics).
Can Azula finish the job future firebenders failed to complete? Or will Amon prove that the past should be left behind?
6/24/12 EDIT: Found out Amon is a Blood Bender. To ensure a non-stomp, he is still under the watch of the Equalists, so he can not reveal he is one to Azula. No hidden place to secretly bend.
