Desna and Eska

I see these two as analogous to Sokka and Katara if their father had been evil, or to Zuko and Azula if both of them had decided to turn against their father. They're also kind of like Mai and Ty Lee in terms of being wild cards that could fall on either the protagonist's or antagonist's side.
