Azula and Ozai would kick all y'all asses! Im talkin like this bastard freakin Scarred his son for life LITERALLY! and his sister shes a cruel bitch you dont mess with her and ozai killed his WIFE. HIS WIFE. well maybe, im actually no 100% sure on that one.
I'm not sure about that. I personally believe that Yakone and his sons are by far the strongest known benders minus the Avatar. Their powers dont really amount to shit if they can control them. The only reason Korra beat Amon was because shoe caught him off guard (aka plot armor)
