Mientras el mundo asimila que han perdido una vez más a su única esperanza, el corazón de Katara se vuelve de hielo. Zutara Fic.

But it was Azula and as soon as she mentioned it with the crazed look in her eyes that showed that her mental state was unstable, he should have known that his little sister would do what she had always done. Play dirty. (Zuko recovers from being struck by actual lightning)

Ursa's return brings many things to Azula's life, but pain is always front and center. Azula-centric, high school/modern AU

Chapter in progress, update coming soon! Zuko sets out searching for his mother, leaving Iroh in charge. Azula is still talking to shadows of her mother, Aang must rebuild an entire culture from scrolls, memories, and sky bison. Noncannon after the series, if you followed the comics.

Another wish fulfillment story of mine, where I call forth my original character Akiko to comfort me.

How he could never really get a full breath in without doubling over, how blood would coat his tongue and stain his teeth when he coughed if he overexerted himself, how he had to keep perfect posture when his chest was bound tightly so they healed correctly. It was practically routine at this point in his life. Takes place after The Boiling Rock

Things go a bit differently after Ozai's defeat. Heartbreak forces Aang to consider a different way to restore balance to the world and within himself. If you enjoy political maneuvering and world exploration and angst and romance, you might like this. Eventual Kataang, but it'll be a bit bumpy on the way.

Multi-chapter.

"Aang was in a tough spot, he wasn't ready at all to heal someone spiritually when he needed spiritual healing himself, the things that he's been through hurt him, he had this nagging feeling that this would end up no different, but he had to do it for Zuko." Aang thought as he knew what he was going to do was nothing short of insanity. [Azulaang story].

It's a busy day in the emergency department for Dr Katara, but the day takes a sudden turn for the worse when the code red alarm rings. Someone must've been in a horrific accident.

Bitter and conflicted feelings arise.

Katara runs into Zuko after the Ember Island play and accidentally admits that she finds him attractive. Fluff ensues in which Katara tells Zuko exactly what she thinks of his scar in more ways than one...

SI/OC After an apartment fire leaves him stranded in the world of Avatar, Alec must decide what to do with his knowledge of this world.

Rated M for Language, Violence, and Mature Themes (NO LEMONS).

Avatar the last Airbender told the story of Aang, of his journey from just a lowly airbender to the lauded Avatar. But what if he wasn't the last Airbender? After all, the Air nomads were an entire country of people, a few of them were sure to slip through the cracks. 100 years later, you get the protagonist of our story, Feng, and the changes his presence makes.

But could things be totally different? When was the moment where things started to shift? Follows canon, but adds a Zutara story. COMPLETE! (Art by beanaroony)

Aang is grievously injured when a peaceful mission goes wrong. Kataang, feat. platonic Zukaang.

/AU-ish/ "You're my brother. That's got to count for something. Right, Zuzu?" If Azula and Zuko had always cared for each other, how different would their live's paths have been?
