When does the new series start?? Do they already have the episodes of The Legend of Korra done with? (are they just waiting to air it?)
My hope for the new series is to bring back Azula I felt they didnt really finish her character in the Avatar series ( just allowing us to see her descend into madness).
My idea has Azula being trapped in like a cryogenic freezer for all those years (they were hoping with time that her mental condition would improve) she is released by a guy mercenary (fire bender/ maybe secret air bender idk) hired by a secret order to free her they get involved in the plot kinda how Zuko was a side story to the Aang's journey in season 2 Azula doesnt understand the new world so she has the guy who freed her guide her through as they find out the master plans of the villains to destroy benders (which would include them since they both bend). As they journey Azula learns how to be a regular person with the guy companion yet still has some troubles dealing with the past, anger, and trust but eventually she starts to trust her companion.
Eventually they decide to team up with Korra to take down the evil rebellion against benders. Like i said they would be like a adventure of their own building up the plot up in til the twist, while Korra discovers her own information about the plot through her adventures.
