Which couple?!?!

Kataang (Katara and Aang)
They're so good together! :) <3

I like Tokka better. Aang gets Katara. Their happy together. Zuko gets Mai and Suki can live a long, lonely life on Kyoshi Island with the Kyoshi Warriors.

Toph and Sokka! ^^
they are both funny, sarcastic and 《勇敢传说》 :]

Taang, just is.

im a zutarian and since aang might be sad about losing katara he needs someone else to make him feel better so im gonna pick taang :-]

Toph and Sokka! Aang has Katara, and Suki could 日期 Haru! :D

Out of the choices 你 gave.. Tokka.

There's at least something to them, I suppose. Something similar, at least a little bit 更多 chemestry. Aang and Toph have no sparks, and have nothing to them other than friendship.

I prefer all of them to be friends, but sinse 你 asked :)

As a side pairing I like Katoph. :) Because it doesn't at all interfere with my Zukaang!

I 爱情 Taang! :)

Aang and Katara <3

由 the way none of them,Sokka loves Suki and Aang loves Katara.

Dude, Toph is what, eight years old? She should not have a boyfriend. Aang goes with Katara, Sokka goes with Suki, that's how it is.
If we're just talking about couples we'd LIKE to see, I'd have to vote for Kataru, Katarra and Haru. But Haru seriously needs to shave that stache
