I love both Avatar:The Last Airbender and The Legend Of Korra. My favorite characters include:
The cabbage man (of course!), Toph, Sokka, Suki, Uncle Iroh, Azula, The Foaming Mouth Guy, all the Ember Island actors (especially the one that plays Toph. That supersonic scream is music to my ears.), Korra, Tenzin, Lin, Jinorra, and Bolin.
My favorite episode of TLA is the Blind Bandit. So far, my favorite LOK episode has been episode 8, but 7 and 6 were close seconds. I love the agni kai between Azula and Zuko in Sozin's Comet and cannot contain my exitement everytime I see her crying and wailing while chained to the grate. That should have won an award for best scene in an animation.
Some of my favorite TLA moments are when Toph yells "Ya, let's break some rules!" and destroys half the house. Also when Sokka is high on cactus juice and when Appa talks to Aang in "Nightmares and Daydreams" and then starts to fight Momo. My favorite moment in LOK is when Bolin gets drunk off of noodles.
I love weird Avatar youtube videos. So here are some links.
