Avatar: The Last Airbender AU (or even just headcanons, because the Host is Toph and no one can tell me otherwise)
(*internal screaming* My time has finally come!!)
Host as Toph makes my heart so happy that I’m actually about to shed a tear!
Bim as Aang most definitely.
Amy as Katara is also just so perfect that it hurts.
Wilford as Sokka even though Warfstache would be an excellent firebender.
BUT I refuse to have Darkiplier represent my beautiful sunflower child Zuko (Dark would be Azula and you know it).
So I’d say Mark as Zuko. I feel like post-redemption arch Zuko is a lot like Mark, and plus, Amy is Katara and ZUTARA SHOULD’VE BEEN A THING AND NO ONE CAN TELL ME OTHERWISE!!! (this is why I don’t discuss ATLA…)
