Ionia is now the Last Airbender universe?

Noxus / Fire Nation - want to conquer for the sole purpose of conquering, disregard harmonious relation with nature that Ionia/the other nations have

Karma/The Avatar - The reincarnation of an ancient spirit that passes wisdom down through the generations and grants the current person near limitless raw power

Yasuo/Zuko - 'betrayed' his family, exiled from his clan and committed to regaining his honor, had to cut off ties to his own family and fight his sibling who's been hunting him down (Zuko probably woulda killed Azula like Yasuo killed his brother if it wasn't a 'kids' show)
