I can tell you why not add Zuko. In order to "properly" add Zuko to the game, he would need to be able to firebend without anything equipped. While it was fairly easy to make Toph able to perform work actions (mining, digging, chopping and... I want to say there's one other one) without tools, attack actions are a lot harder to work with. I've tried, and I can't figure it out for the life of me. It would take very intimate knowledge of how Don't Starve is laid out, and probably some weird workarounds. While it would be great to see the entirety of Team Avatar in Don't Starve, I just don't think that making Zuko happen is very practical.

Zuko was my favorite... Besides Katara and her "Hair Loopies" XD

Well, what about Sokka? Sokka! Everybody loves Sokka!

Oh... So that was his name... I forgot...

The ending where he painted that painting that angered everyone...

Ooh! Add Momo! Was that his name?... Monkey-animal-cute-thing!

Sokka done as a male wigfriend who cna eat veggies but gets more hp and stamina from meat, remove the kill bonus, keep bonus to stats in combat and you have a winner right there., ang would be pretty cool to see too, shouldnt be too hard to get air bending effects(speed,push things away wind blast,ability to use sound based attacks with instruments)

For Sokka, I imagine that he would get a bonus to science (he has a natural curiosity!), but penalties to magic, or just outright be unable to use it. I figure this means he would have increased maximum sanity and perhaps not be as horribly influenced by the sanity auras of various monsters. He would, of course, begin play with an unbreakable boomerang, and I imagine that he would gain additional sanity (or lose less sanity, as appropriate) from eating meat. I also suspect that he would dress warm, making him less likely to freeze in winter.

If you would ad Aang, you would have to make him a vegitarian. So no meat eating at all. But I guess because of his calm nature he would get a bonus on sanity and maybe even health and hunger. Maybe even able to befriend more creatures that are hostile to others

I had forgotten that he's vegetarian. Thanks for the reminder. That said, airbending is something that will be both hard to code and wouldn't have much impact in-game. IF I'm going to make more Avatar mods, Aang is going to be last.

Here is how i invision aang working from a modders perspective, realizing that i'm NOT a modder myself.

Simply generate him to start with his glider (in stick form) that has magic effects (similar to a wand in the game). While this wouldn't be 100% accurate, it would solve a lot of the problems.

1) Sokka isn't a bender at all. He has no bending powers.
2) When Epic said "ang", I'm guessing you read that as "and." Actually, what he meant was "Aang."

Wait... In some episode didn't he try to bend,and have it work in some way?

Pretty sure that didn't happen.

Hmm... He is a Metal Boomerang bender. He is officially a bender now. Now the world will love me for getting him in the bender class.
