In a world where the Avatar wasn't found, the Fire Nation took over two nations and they strive to overcome the last one. Water Tribe warrior Sokka seeks to fight for his people's rights, but he's captured by his enemies. His life is no longer in his hands as he fights as a Gladiator, and his fate will eventually depend on the Fire Nation Princess, who needs him for her own ends...

Zuko and Piandao having a conversation.

Katara: two years of isolation chasing after her brother who vanished into the Earth Kingdom looking for work. Zuko: six years of isolation on an iron ship slowly losing hope that his horizon might ever change. After coming to realize his father never meant for him to return home, Zuko throws his fate in with Katara's side, but halting one hundred years of momentum isn't that easy.

The war is finally over but Aang is heart broken after seeing Katara and Zuko together. To avoid the pain, he makes a decision.

Katara is still angry at Zuko, but when he offers to help her find her mother's killer, she doesn't refuse. Things don't go as planned though, and Zuko and Katara are surprised they understand eachother much more than they ever thought possible. Set around the Southern Riders episode, follows the GAang until after the war. Everyone is aged up. Zutara.

Trying to rediscover purpose and reclaim his heroic stature, Sokka embarks on a mission to track down Azula, intending to bring her back to the Fire Nation and collect the bounty on her head. Just as he believes he has the upper hand, Azula shows him who's really in control. They say there's a thin line between lust and hate. Wait… that's not it.

Sequel to the canon-divergent and early-Zuko-join fic Catalyst, Catastrophe starts at the beginning of book 3 and follows the Gaang through to Day of Black Sun. Zuko continues to wrestle with his feelings toward the Fire Nation, his family, his friends, Katara, and the war as the time for the invasion arrives, and what it means to finally be "good."

The war was finally over, but there are now a lot of lose ends to tie up. Has peace really been achieved for the world? Will Aang and Katara finally get together? Was Ozai the last villain that the Gaang would have to face? Kataang, rated T for mild violence and romance.

Collection oneshots. Little stories based on advice for Aang given to him by one of his friends. Kataang fluff.

Working undercover to bring down a growing crime family in Republic City, the Criminal Investigation Bureau's top special agent finds herself in a spot of trouble...

An AU story. Zuko has managed to capture the GAang. With no options left, Katara picks up on Zuko's attraction to her and offers him a deal, one night with her in his bed for Aang's release. She convinces him to take the deal, but the experience may prove to be very different than what she expects. Can she resist the attraction between them, or will she succumb to temptation?

When Zuko and Sokka meet as children after the Southern Water Tribe is not only invaded, but conquered by the Fire Nation, they realize unlikely alliances can be formed in war. Now, the boys can let the differences between their families and cultures bring them together to stop the bloodshed or allow the years of hatred to win before the war is even won.

As the eldest son of the chieftain he was tasked with protecting the village & his younger siblings Sokka & Katara. After their mother's death too much changed. To keep his remaining family safe he had to close off his heart and train relentlessly. The Avatar wasn't coming back. Or at least, that's what Ayaan thought, until a bald kid with blue arrows showed up.

This was inspired by ATLA, specifically the Season 2 Finale. The story follows the Gaang in alternate storyline where Zuko finds the right path sooner. At "The Cross Roads of Destiny" Zuko decides to join Team Avatar after connecting with Katara over the loss of their mothers. Katara sees that Zuko has just been lost up until this point and uses the spirit water on his scar.

Aang shows Katara what color her eyes are. Kataang fluff.

Alice wakes feeling fuzzy, she awakes to see someone who looks a lot like Katara... But life like version of her... Is she dreaming or is it so much more... Can she save lives and change destiny! OC, FaninWorld OCxZuko

The exchange in Omashu goes anything but how Azula expected it to. Spirit shenanigans ensue, and suddenly the princess of the Fire Nation finds herself shrunken down to her child form.

Azula goes into hiding in the earth kingdom to escape imprisonment from Zuko and is being chased by the Avatar but after a strange ship from the sky crash lands Azula finds herself on board when it takes off unwillingly taking her into the stars with it. Now Azula finds herself amongst a crew of alien creatures traversing strange alien worlds.

Zuko has hurt Ty Lee and he doesn't know what to do. After being banished, Zuko makes it his personal mission to capture the Avatar so that he could return home reunite with Ty Lee, so he can make up for his wrongs. This is a Ty Luko story and a Rated M version of the original "I Love you and I'm Sorry."

Zuko had made the biggest mistake of his life. He didn't mean to hurt her, though. It happened at the wrong place at the wrong time. How will Ty Lee recover from her wounds and how would Zuko get over this guilty conscience? Only time will tell.

Aang has to return to the South Pole on the eve of the Winter Solstice because of the problems that have arisen. He is expected to meet Katara, who broke his heart three years ago. Will they be able to start all over again, or are they lost to each other forever. Kataang and platonic Azulaang.

Peace? What a pipedream. True peace only comes when you beat the other guys up so hard that they become part of you and never raise arms again. That's the only end to the 100-year war I'm willing to accept. (An SI into a fire bender OC in the middle of the war is forced to come to terms with the realities of the world he now inhabits)

Aang had always thought that Katara was the one he would end up with as the two of them got older, but he was very wrong. When tensions start to rise among the group, and Katara’s eagerness to help Aang with everything soon becomes too much for the young Avatar to handle, he finally snaps at her. Mounting stress causes Aang to go into the Avatar State and he loses control.

ATLA-retelling with an OC! After the first encounter with the Avatar at the South Pole, Zuko wants to repair his ship as quickly as possible. He did not expect to see a girl from his past come back into his life, not now when everything has to be focused on finding the Avatar. Yet destiny has a way of its own. /Book 1: Chapter 1 - 26. Book 2: 27 - 49. Book 3: Chapter 50 - ongoing

What would happen if in the events of Pohuai Stronghold Zuko instead of being knocked out, was hit with the arrow and his identity was compromised? His journey is about to take a whole different turn on early stage.
