Really good chapter, I feel like you wrote all the characters well, and the plot is very interesting. I really hope you continue this story, I believe it would be Amazing

This is great! keep up the good work. really hoping this isn't a one shot, love the premise and judging from this you have the skill to do it justice.

Loving it!

Make another one or add more chapters this deserves to be more than a one shot story arc

The way that this ended was really clever. Nice way of avoiding rehashing the original episode just with swapped names. The character work was pretty good for most of them, especially with Sokka, which is doubly impressive considering that he's not the POV character at all in this story. Azula I was a little spotty on in some parts, but then again her decision close to the end really clinched the deal for me. Nice work all around!

This is so cool! it is just different and I like it. Have you thought of making it into a story?

At first I was like, “The Water Tribe? What can The Water Tribe do that’s as bad as using a comet to burn the earth?” ...And then you mention blood bending. ...Yeeeeah... Katara blood bending would probably be comparable to Azula lightning bending. That type of thing makes the Water Tribe much more of a threat. Hmm... I wonder if they can drown nations... The Fire Nation might look like the Southern Water Tribe in this AU.
...I wonder what Sokka can do. And if he has something to teach Aang if he teams up... So far, it sounds almost like he’s a mix of Zuko and Sokka, where Azula notes how composed he is, yet he also got stuck in a chimney and was working on a plan to get out. Also... can’t Toph do her lie detector thing on him? Is he good at lying, like how Azula is in the series?
It’s an interesting thought that a non-bender might could teach bending if they understand it well enough. It might work for Aang, who’s naturally gifted, but I wonder if it’d be possible to teach some other bender... If this all works out, it would be interesting to see how a lesson would go. Also, when Toph mentions the need to find a water bending teacher, it makes me wonder if they’d run into a friendly water bending teacher back in season one. Like Pakku. (How big is this AU you‘re writing for?)
...I think it ended too soon. (pouts)
